Description

  The present invention relates to a waterproofing member for a roof that is constructed in a roof ridge and used for preventing rainwater from entering the attic.

  The waterproofing measures that have been applied to the ridges with tiled roofs have long been built by placing ridges and plaster on the top of the ridges, and then spreading the ridge tiles. As a result, not only waterproofing measures but also the so-called face door finish is beautiful and the design of the entire roof is excellent. However, ridges and plasters are prone to soiling other than the ridges of the roof during construction, and the moisture in the ridges will disappear after construction, and the parts that have become brittle after peeling or shrinking will peel off. Yes, it was not perfect as a waterproof member. In addition, because of its considerable weight, many studies have been made to reduce the weight.

  In recent years, the weight of roofs has been reduced, and so-called dry construction methods are becoming popular in the construction of roof ridges. As an example of the dry construction method, a sheet-like material having a water-stopping performance for covering between roof materials in place of plaster is used. According to the invention described in Patent Document 1, as shown in FIG. 12, the central strip 50 has a non-woven material 51 that allows air to pass through and repels water, and a soft and stretched metal material embedded therein. There is a sealing strip 5 that is made of a polyisobutylene sheet material 52 that can be formed and has elasticity in both the length direction and the width direction.

  With this configuration, butyl rubber or the like is in close contact with the roof tiles on the roof ridge, preventing rainwater from entering, and ensuring the ventilation of the ridge.

  The invention described in Patent Document 2 also has a roof waterproof member having a similar configuration. According to this invention, as shown in FIG. 13, the tear-resistant and heat-shrinkable elastomer sheet is bonded to the front surface side of the aluminum foil using an adhesive, and the resin coating is applied to the back surface side of the aluminum foil. There is a coated multilayer tarpaulin 7.

  With this configuration, the installation of waterproof sheets on roof ridges and walls can be adapted to the site installation shape in buildings with various types of roof materials and roof gradients, which makes it easy to construct and general-purpose. Excellent in properties.

  However, the inventions described in Patent Document 1 and Patent Document 2 have room for further improvement. When trying to construct a waterproofing member for roofing, install the waterproofing member for the roof in the initial state wound in a spiral shape in the longitudinal direction of the ridge rafter, but it can be bonded to the grounding part of the ridge rafter and fixed Since there is no function, it was necessary to work while fixing the ventilation part and the ridge rafter with a staple needle using a tucker or the like while aligning the center of the ventilation part with the center of the ridge rafter.

  Although the waterproofing member for roof can be constructed by this method, on the other hand, the staple-like one used when fixing the ventilation part and the ridge rafters opens a hole in the ventilation part. In addition, a screw for fixing the ridge tile to be installed on the ridge rafter also has a hole in the ventilation part, and rainwater that has entered from the screw etc. through the screw hole passes through the hole opened in the ventilation part. Wet the rafters and infiltrate the internal openings. As a result, there was a risk of causing rain leakage. As another problem, since fixing with the staple needle-like one is generally performed at a certain interval in the direction of the ridge rafter, the waterproofing member for the roof of the part where the periphery is not fixed is used. If it is going to fix a ridge tile to a ridge rafter, the waterproofing member for roofs will be rolled up by the rotation effect | action of a screw. This is because there is a slight difference between the timing when the tip of the screw penetrates the roof waterproofing member and the timing when it is screwed into the ridge rafter, until the screw starts penetrating through the roof waterproofing member This is because the waterproofing member for roof is attracted to the upper side of the rotating screw for this time. This state has a problem that the waterproof layer of the waterproofing member for roof is broken, and the construction is not firmly applied to the ridge rafter.

  As another issue, this kind of waterproofing member for roofs can achieve high design and high waterproofing performance only when the right and left sides are even with respect to the ridge rafters. It was particularly difficult to construct properly, as the length became longer.

  In view of the above, the object of the present invention is to provide a waterproofing member for roofs that can be fixed to a ridge rafter without using a fixing tool such as a staple needle in the ventilation part of the waterproofing member for roofs, and can eliminate any risk of rain leakage. Is to provide.

  In order to solve the above-described problems, the waterproof member for roof according to the present invention is wound in a spiral shape before construction, and can be expanded and contracted in the length direction and / or width direction at the time of construction. A waterproofing member for a roof constructed in a part, wherein the waterproofing member for a roof has an adhesive layer on both sides in the width direction, and a waterproofing adhesive surface is provided on a contact surface of the roofing waterproofing member with a ridge rafter. Adopt the configuration.

  By employ | adopting said structure, when fixing a ridge rafter and the waterproofing member for roofs, it can construct without difficulty, without using tools, such as a tucker. In addition, when fixing the roof tile to the roof rafter, even if the waterproofing member for roof is pierced by a screw, the water-blocking adhesive surface prevents water from entering from the hole through which the waterproofing member for roof is pierced. Can do.

  Moreover, in order to exhibit said invention more effectively, at least 1 or more construction reference line 16 corresponding to the width | variety of the center line 15 or the ridge rafter 33 extended over a longitudinal direction is provided in the surface side of the said nonwoven fabric layer. Adopt the configuration. By adopting this configuration, the waterproofing member for roofs, which was difficult to adjust to the right and left in the ridgeline direction in the past, can be easily centered on the ridge rafter with reference to the construction reference line. It does not take time and effort. Of course, even more so if you have a centerline.

  The roof waterproof member of the present invention makes it possible to fix the roof waterproof member to the ridge rafter without using tools such as a tucker, and to quickly fix the roof waterproof member. Furthermore, even when screws or the like break through the roof waterproofing member when the ridge tile is fixed to the ridge rafter, rainwater or the like that has entered the interior space of the ridge tile does not enter, and higher waterproof performance can be exhibited. And since the waterproofing member for roofs can be constructed with good balance with respect to the ridge rafter by the construction reference line, the construction accuracy is high and the work efficiency is improved.

  Examples of the present invention will be described in detail below.

[Basic configuration]
First, the basic configuration of the waterproofing member 1 for roof according to the present invention will be described. As shown in FIGS. 1, 2, and 5, the roof waterproof member 1 of the present invention is mainly composed of a nonwoven fabric layer 10, a waterproof base material layer 11, a metal film layer 12, an adhesive layer 13, and a release paper 14. It is made up of.

  As in the prior art, the basic shape of the waterproofing member 1 for roofs according to the present invention is long and band-like on one side, and is wound in a spiral shape in a normal state (state before construction). Moreover, although the cross-sectional view is generally a thin film, it is folded back in a Z-shape or an inverted Z-shape upward from both edges toward the center near the center of the width direction center and both edges. Is provided. This turn-back can be expanded and contracted in the width direction.

  The nonwoven fabric layer 10 is formed in the uppermost layer of the waterproofing member for roofs, and has a certain width and the same length as the length of the waterproofing member for roofs. The material of the nonwoven fabric layer 10 shall select suitably the material described in the well-known technique, and is comprised by nonwoven fabrics, such as polyethylene and a polypropylene, as an example. The non-woven fabric layer 10 is partly and entirely bonded to a later-described waterproof base material layer 11, and is highly waterproof as a primary waterproof layer so as to prevent rainwater or the like that has entered from the surface of the roof tile from entering the interior. Has water repellency. This nonwoven fabric layer 10 also has an effect of ventilating air rising from the back of the cabin through the opening. In addition, since the nonwoven fabric layer 10 should just be able to ventilate rainwater etc. without infiltrating into the opening provided in the ridge part, the full range is not provided in the width direction, but from the center line of a longitudinal direction. Although it should just be provided in the range of about 30-100 mm, and especially desirably about 50-80 mm, it is not limited to this and is provided in the necessary range as appropriate.

  Further, as another effect of the nonwoven fabric layer 10, it is a kind of printed surface such that various notations 10a as shown in FIG. 3 are drawn, and the notation 10a includes a product name, a model number, and a manufacturing date. In addition, there are instructions for the construction procedure and direction of construction. The roof waterproofing member 1 of the present invention is provided with the overlapped portion A continuous in the longitudinal direction, so that the longitudinal direction can be somewhat expanded and contracted, and is a surface of the roof material 32 having a complicated shape. Can be easily adapted (can be transformed into a shape that conforms to the shape of the roof surface, eliminates the gap with the roofing material 32, and is firmly waterproofed). In particular, when the roof material overlaps, for example, in the case of clay tiles, a step of about 25 mm at maximum may occur. Therefore, even if there is a high level difference, the overlapped portion A can be constructed without any gap by extending somewhat in the longitudinal direction (including partially extending in the width direction) (as an example, FIG. 9). This is not limited to the step, and the same applies to the case where the roof material surface is greatly curved. The overlapped portion A is preferably configured in a certain direction, and is repeated in such a manner that one side is overlapped with the other from the top, and the direction of the eave side at the time of construction overlaps from above. It is desirable that With this configuration, even if rainwater adheres to the waterproofing member 1 for roofing, the rainwater can flow smoothly, and even a slight amount of water leaks and corrosion of the waterproofing member for roofing itself can be suppressed. Can be expected. Since these are especially conspicuous in the corner building 20, the nonwoven fabric layer 10 needs the notation 10a of the construction direction.

  The waterproof base material layer 11 is formed below the nonwoven fabric layer 10 and is substantially integrated with the metal film layer by an adhesive. The waterproof base material layer 11 has a high waterproof performance as a secondary waterproof layer so as to prevent rainwater and the like from entering the back of the hut, similarly to the non-woven fabric layer 10, and bends easily in cooperation with the flexibility of the metal film layer 12. It has an excellent effect. A specific example is a thermoplastic elastomer or the like. The waterproof base material layer 11 preferably has a thickness of about 0.1 mm to 0.5 mm, particularly about 0.3 mm. The waterproof base material layer 11 is provided in the entire width direction of the waterproofing member 1 for roof, and in the range where the nonwoven fabric layer 10 covers upward, the metal film layer 12 and the vent holes 12a are desirably arranged in two or more rows in the width direction. Is provided with about 3 to 10 vents 12a having a diameter of about 5 to 20 mm per 10 centimeters in a length of 4 rows or more. This vent 12a can ventilate the air which has risen from the opening (not shown) between the field boards constituting the ridge. The vent 12a is entirely covered with the nonwoven fabric layer 10 provided on the upper portion, and is near the center in the width direction so as not to contact the upper surface of the ridge rafter 33 in the construction state of the roof waterproofing member 1. Arranged to avoid. Here, as for the length of the superposition | polymerization part A, the actual length (length when all the superposition | polymerization part A is fully extended) with respect to general length (the state of un-construction which unwound the spiral) is about 110-150%, especially Since it is provided to be about 116 to 133%, it can be expanded and contracted in the longitudinal direction. In addition, the overlapping portion A is repeatedly configured in a state where the waterproof base material layer and the metal film layer are integrated.

  The metal film layer 12 is formed between the waterproof base material layer 11 and an adhesive layer 13 described later. The purpose of the metal film layer 12 is to use the plastic characteristics of the metal film, so that when the waterproofing member for roofs of the present invention is applied to the uneven surface of the roof, the shape of the metal film layer 12 can be easily adjusted to the uneven surface of the roof. It is for putting it on. The metal film layer 12 is formed in a thin film of about 30 μm to 90 μm in consideration of being able to cut the waterproofing member 1 for roof by hand processing and adapting to the roof surface. As a material, a general aluminum foil is used as an example, but a material is appropriately selected in consideration of cost and workability. The metal film layer 12 may be provided with a vent 12a at the same location together with the waterproof base material layer 11 as described above.

  Although not shown, the metal film layer has a resin coating on at least the lower surface (the roof material 32 side), and in addition to the purpose of improving durability and corrosion resistance against metals such as aluminum foil, The object is to prevent the metal film from tearing easily against deformation or the like. The material of the resin coating is an epoxy resin type, an amino resin type, a melamine resin type, and the like, and the thickness of the resin coating is about 0.5 μm to 5 μm. Just choose.

  The adhesive layer 13 is a part that is provided below the metal film layer 12 and directly adheres to the roof material 32 of the ridge. Therefore, it is required to be provided in the vicinity of both end portions in the width direction, to be sufficiently adhered to the roofing material 32, and to be excellent in waterproof properties so that rainwater or the like does not enter the building from the adhesion surface. The adhesive layer 13 is preferably butyl rubber, for example. For example, the width of the pressure-sensitive adhesive layer 13 is preferably about 10 mm to 50 mm with respect to the width direction of the roof waterproofing member 1 and particularly preferably about 30 mm so that the adhesive strength and waterproofness to the roof material 32 can be sufficiently exhibited. Further, the thickness (height) of the pressure-sensitive adhesive layer 13 is preferably at least 0.5 mm or more, and sufficient adhesive force can be obtained for the roof material 32 having large irregularities if the thickness is within a suitable range of about 2 mm.

  The release paper 14 is formed in the lowermost layer of the waterproofing member 1 for roof and covers the adhesive layer 13. The release paper 14 is bonded to the pressure-sensitive adhesive layer 13 but is made of a highly peelable material that can be easily peeled depending on its use. Since the said adhesion layer has adhesive force, when constructing the waterproofing member 1 for roofs, possibility of making it adhere unexpectedly to a location unexpectedly is considered sufficiently. The adhesive layer 13 is in a state of covering the adhesive layer 13 before construction of the waterproofing member 1 for roofing, since it takes labor to peel off or remove the adhesive layer 13 when it is adhered to another material. A release paper 14 is provided so that it can be easily peeled off if necessary. Desirably, the release paper 14 is slightly wider than the width direction and slightly longer than the length direction so that it can be easily peeled off from the adhesive layer 13 so that it can be easily pinched with a finger. .

  The basic configuration of the waterproofing member for roof 1 according to the present invention has been described above, but these are easily configured by a known technique or the like. A feature of the present invention is that the waterproof surface 1 is provided with a waterproofing adhesive surface 13a on the contact surface with the ridge rafter 33 constructed in the roof ridge portion of the waterproofing member 1 for the roof, and the center line 15 on the nonwoven fabric layer 10 There are two features in that another construction reference line 16 is provided. These points will be described in detail below.

[Configuration of water-resistant adhesive surface]
First, as shown in FIGS. 1, 3, 4, and 5, the water-stopping adhesive surface 13a of the present invention has a longer longitudinal center than the other conventional waterproofing members for roofs. It is different in that it is provided in a strip shape over the direction. The waterproofing adhesive surface 13a of this part is located on the upper surface of the ridge rafter 33 when the waterproofing member 1 for roof is constructed on the ridge, and is not displaced from front to back and left and right by the adhesive force to the ridge rafter 33. effective. Further, since the roof waterproofing member 1 is fixed to the ridge rafter 33 by the water-proof adhesive surface 13a, it is not necessary to fix the roof waterproof member 1 with a staple such as a tucker. Furthermore, since the upper surface of the ridge rafter is covered with the waterproofing adhesive surface 13a, when the ridge tile 35 is fixed to the ridge rafter 33 with the screw 34, the nonwoven fabric layer 10 of the roof waterproofing member 1, the waterproof base material layer 11, Even if it penetrates the metal film layer 12, the water-stopping adhesive surface 13a exhibits a high water-stopping property so that rainwater or the like does not enter from the ridge. In short, the adhesive layer 13 and the waterproofing adhesive surface 13a of the waterproofing member 1 for roof of the present invention are provided in a total of three strips at the center and both ends in the width direction, and the waterproofing adhesive surface 13a at the center is the mushroom 33. The roof waterproofing member 1 is fixed by adhering to the upper surface of the roof, and even if the screw 34 penetrates by fixing the roof tile 35, rainwater can be prevented from entering. It can be adhered to the surface to prevent rainwater from entering from the surface.

  As shown in FIGS. 3 and 4, the basic structure of the water-stopping adhesive surface 13 a of the present invention is provided in a band shape from the center in the width direction of the waterproofing member 1 for roofs in the length direction. The width of the water-stop adhesive surface 13a is preferably about 20 to 50 mm, and particularly preferably 30 to 45 mm. This width is set to substantially coincide with the width of the upper surface of the ridge rafter 33 to be constructed in the ridge, but the water-stopping adhesive surface is substantially at a position where the screw is fixed to the ridge rafter 33 at least when the ridge tile 35 is fixed. Since 13a is sufficient, the width may be narrower than the width of the ridge rafter 33, and it is only necessary to have some width at a substantially central portion in the width direction of the ridge rafter 33. Moreover, the material of the water-stop adhesive surface 13a may be comprised, for example with butyl rubber etc. similarly to the adhesion layer. That is, it is desirable that the water-stopping adhesive surface 13a has a function that can be sufficiently bonded and fixed to the ridge rafter 33 and a waterproof function against rainwater or the like. Moreover, by having these functions, the waterproofing member 1 for roof can be constructed by the waterproofing adhesive surface 13a even in the step of passing the screw 34 for fixing the roof tile 35 through the waterproofing member 1 for roof and screwing it into the rafter 33. Since it is continuously bonded to the rafters 33, it has sufficient adhesive strength, and the roof waterproofing member 1 is not wound up by the rotating operation of the screws 34.

  Furthermore, almost the entire surface of the water-stopping adhesive surface 13 a of the present invention is covered with the release paper 14. Even if the waterproofing adhesive surface 13a is unexpectedly attached to the roof surface or the roofing material 32 by this release paper 14, it will not be caught or soiled at those locations. The release paper 14 is the same as or slightly wider than the width of the water-stopping adhesive surface 13a, or the same length or the same length with respect to the length direction of the water-stopping adhesive surface 13a. Is also slightly longer. Thereby, the release paper 14 can be easily peeled off when the waterproofing member 1 for roof is constructed. In short, the water-stopping adhesive surface 13a has the same properties as the adhesive layer 13, and the arrangement with respect to the waterproofing member for roof 1 is different.

  Here, as shown in FIG. 6, when the nonwoven fabric layer 10 in contact with the water-stopping adhesive surface 13 a is made of a peelable material in a state in which the waterproofing member 1 for a roof is wound in a spiral shape, The waterproofing adhesive surface when the waterproofing member 1 for the roof is made into a spiral instead of the release paper 14 so that the waterproofing adhesive surface 13a of the waterproofing material is not adhered to another part of the waterproofing member 1 for the roof itself. The structure which makes the layer provided in the upper layer further from the nonwoven fabric layer 10 of the site | part in contact with 13a or a nonwoven fabric layer as the peeling layer 14a with peelability is also possible. If it is this aspect, the waterproofing member for roof 1 itself will not be soiled without attaching the release paper 14 to the water-stopping adhesive surface 13a, and it can be applied immediately because there is no time to peel off the release paper 14. Moreover, the waste of the release paper 14 at the construction site is not generated. In consideration of the state in which the roof waterproof member 1 is stored in a spiral shape, the release paper 14 may be pasted for a length of the outermost circumference of the roof waterproof member 1 wound in a spiral shape. .

[Configuration of construction reference line]
Secondly, the present invention is also different from the prior art in that the construction reference line 16 corresponding to the width of the center line 15 and the ridge rafter 33 is provided on the surface side of the nonwoven fabric layer 10 of the waterproofing member 1 for roof. There are features. That is, in the prior art, only the center line 15 is often provided at the center of the waterproofing member 1 for the roof, and the center line 15 is aligned with the ridge core to adjust the left and right balance. In the construction work, there is a problem that it is difficult to match the ridge core and the center line 15. Accordingly, in the present invention, the construction reference line 16 corresponding to the width of the ridge rafter 33 is provided to solve this problem.

  The construction reference line 16 of the present invention is provided with a construction reference line 16 different from the center line 15 as a guide for construction at the center in the length direction on the surface side of the waterproofing member for roofs, which is an existing technology. As shown in FIGS. 3, 5, and 7, the construction reference line 16 is provided at the same interval from the center line 15 at least one, preferably two or three, on the left and right sides with respect to the ridgeline direction. The interval between the two construction reference lines 16 corresponds to the width of the ridge rafter 33 described above. As an example, when the width of the upper surface of the ridge rafter 33 is 42 mm, the distance from the center line 15 to the left and right construction reference lines 16 is preferably 21 mm, and the construction reference line 16 and the upper edge of the ridge rafter 33 are on the same line. It is desirable to be located at. In this manner, when construction of the waterproofing member 1 for the roof is started, the center line 15 is aligned with the approximate center of the ridge rafter 33 or one edge of the top surface of the ridge rafter 33, and the construction reference line 16 is aligned with the ridge rafter 33. If it is constructed according to the edge of the upper surface (the other edge), the roof waterproofing member 1 can be constructed on the ridge with reference to at least two lines (two points). As a result, the construction accuracy of the waterproofing member for roof 1 can be improved and positioning can be easily performed.

  Moreover, as another structure, as shown in FIG.4 and FIG.6, the line (center) different from the construction reference line 16 provided in the nonwoven fabric layer 10 on the adhesion surface itself with the ridge rafter 33 of the water-stopping adhesive surface 13a. Line and construction reference line). Thereby, when the operator of the waterproofing member for roof 1 constructs the water-stopping adhesive surface on the ridge rafter 33, while constantly checking the alignment of the center and the edge with the line provided on the water-stopping adhesive surface, Since construction can be performed, construction accuracy can be improved and construction time can be shortened.

  As for the width of the ridge rafter 33, various dimensions are used depending on the construction site of the roof, and even if examples thereof are 40 mm, 42 mm, 45 mm, etc., the above-mentioned construction reference line 16 has the above-mentioned dimensions and the like. You may provide about three types according to the width dimension of a containing ridge rafter. At this time, since there are no large differences in the width of the ridge rafter, the construction reference lines provided in plurality are close to each other, so when providing two or more construction reference lines, each construction reference line is identified. The line type, line color, line thickness, etc. are changed so that they can be easily determined, and the structure can be distinguished at a glance. For example, when there are three construction reference lines each on the left and right, when distinguishing by line type, solid lines, dotted lines, and alternate long and short dash lines, and when distinguishing by line color, black, white, and red (however, construction standards The color of the nonwoven fabric layer provided with a line is excluded), and when it is determined by the line thickness, it is 0.3 mm, 0.7 mm, or 1.0 mm. Alternatively, a combination of these three types of identification elements may be used. In addition, an identifiable method is selected by an optimum means.

[Example of construction]
As an example, a procedure for constructing the waterproofing member for roof 1 of the present invention will be described below. In this embodiment, the explanation will be given assuming the construction with the most standard dormitory roof with one large building and four corner buildings.

  The modified asphalt or other roofing is applied to the roof surface that has been constructed up to the base plate, and the tile piers for hooking the tiles are fixed at a predetermined pitch (all not shown so far). Next, the ridge bracket 31 is fixed to the ridge at a predetermined pitch in the ridge direction, and the ridge rafter 33 is fixed to the ridge bracket 31. Subsequently, the roofing material 32 is constructed from the eaves side and constructed to the ridgeline. Up to this point, the construction method is the same as that for ordinary tiled roofs. From here, the waterproofing member 1 for roof of this invention is constructed.

  As shown in FIG. 8, when both the large ridge 21 and the corner ridge 20 exist on the roof 2 to be constructed, the construction is performed in the order of the corner ridge 20 and the large ridge 21 in consideration of the waterproof surface. First, the width on the upper surface of the ridge rafter 33 is measured in advance, or the construction reference line 16 that substantially matches the edge of the ridge rafter 33 is confirmed while the waterproofing member 1 for roof is temporarily placed on the ridge rafter 33. Keep it. In addition, while confirming the notation 10a of the nonwoven fabric layer 10, confirm the direction in which the continuous fold-side of the overlapped part A is directed toward the eave side and the valley-folded side toward the ridge side (the state before construction is It is spiral, and when the end of the roof waterproofing member 1 is pulled out during construction, the direction of pulling out is always overlapped with the mountain fold side). Next, the end of the waterproofing member 1 for roof according to the present invention is somewhat protruded from the eaves side of the end of the ridge rafter 33, and folded so as to wrap around the end of the corner ridge on the most eave side (in the case of corner ridge construction). (The release paper will be removed as appropriate). When the construction of the corner ridge tip is completed, the water-stopping adhesive surface 13a is applied to the upper surface of the ridge rafter while peeling off the release paper 14 of the waterproofing member 1 for the roof in accordance with the center line 15 and / or the construction reference line 16. Then, the adhesive layer 13 is bonded in the same manner to the surface of the roof material 32 at the ridge (FIG. 9). At this time, according to the uneven shape of the surface of the roofing material 32 and the covering range of the roof tile 35, the roof waterproofing member 1 is appropriately expanded and contracted in the longitudinal direction and the widthwise direction so that there is no gap with the surface of the roofing material 32. And then install. And it repeats to this and repeats to the ridge side edge part of a longitudinal direction.

  When the construction has been completed up to the ridge top 22 (three branches) in all the corner ridges 20, the roof waterproofing member 1 is laid on the large ridge 21. As shown in FIG. 9, paying attention to the roof waterproofing member 1 constructed in the corner ridge 20 so that there is no gap in the ridge top 22, it is constructed on the ridge rafter 33 and the roof material surface in the same manner as the corner ridge 20. . When the construction of the ridge is completed, as shown in FIG. 10, a corner ridge roof tile, a ridge tile, a three-piece roof tile, etc. are constructed on the ridge rafter 33 and fixed with screws 34 or the like to complete the roof 2. In addition, since the waterproofing member 1 for roofs is firmly fixed to the ridge rafter by the water-proof adhesive surface 13a, the roof waterproofing member is rolled up when the corner ridge roof tile, the ridge tile, the three-piece roof tile, etc. are constructed. The finish is fully achieved.

  The roof waterproofing member 1 according to the present invention simplifies the construction work and improves the workability, and also only aligns the construction reference line 16 with the edge of the ridge rafter 33. It is possible to suppress variations due to. Moreover, as shown in FIG. 11, the waterproofing adhesive surface 13a is given to the upper surface of the ridge rafter 33, and the waterproofing member 1 (nonwoven fabric layer 10) for roofing by screwing the ridge tile 35 is damaged (a hole is opened). There is no problem with water stoppage even if there is a state.
