The flashing has a malleable base member adapted to be mounted over the aperture made in the roof and on a surface of the roof surrounding the aperture and to match the shape of roof surface. The base member comprises a panel having edges adapted to be positioned on the roof and an opening large enough to allow passage of the chimney therethrough. The flashing also comprises a surrounding member being tubular in shape and extending upwardly from the base member to fit around the chimney. The bottom and surrounding structures are linked through a joining ring structure encircling a bottom opening of the surrounding member.
Description
- The present invention relates to a flashing useful for weatherproofing an aperture made in a roof. More particularly, it relates to a flashing adapted for use on a roof having different shapes.
- It is of common practice in the construction industry to use a flashing to seal the interstitial gap between the roof and a vertical member such as a pipe, a venting duct or a chimney passing through an aperture made in the roof. In addition to ensuring weatherproofing of the roof aperture, the flashing is usually also devised to ensure proper drainage of the water that can accumulate on the roof.
- However, due to the different profiles and overall shapes of-various roofing components such as tiles used on roofs, current factory-built flashings do not provide adequate sealing of the gap between the vertical member and the roof and, in several cases of tiled roofs, flashings are difficult or even impossible to install.
- It is common practice on construction sites to use lead flashings to be dressed to match the shape of roof tiles. Unfortunately, most pre-fabricated chimney installers are not familiar with this practice. Consequently, installation of the flat base of a pitched flashing positioned over an aperture made in a tiled roof and fastening of the flashing on a roof that does not have a generally flat surface becomes problematic.
- Certain prior art flashings have attempted to solve sealing problems between the vertical member and the roof by using combinations of malleable materials that are adaptable to different roof shape profiles. Such combinations use a surrounding member made of EPDM rubber or silicone to fit around the vertical member. The surrounding member is attached to an aluminum base member that can be adapted to the shape of the roof surface. Unfortunately, the use of rubber or silicone is not advisable when the flashing is used to seal the gap between a chimney and a roof, due to the high temperatures that may be attained at the outer surface of the chimney. Certification of the use of such flashings with chimneys is therefore complicated due to the choice of materials.
- Thus there is still presently a need for flashings that are easily adaptable and that can be easily installed on a variety of shapes of tiled roofs or the like having chimneys extending therefrom.
- An object of the present invention is to provide a roof flashing for use on a roof, different from known pitched flashings, more particularly for use on different shapes of tiled roof.
- More specifically, the object of the present invention is to provide a flashing for weatherproofing an aperture made in a roof, to allow the passage of a chimney through the roof.
- Like existing pitched flashings, the flashing according to the invention comprises a base member adapted to be mounted over the aperture made in the roof and on a surface of the roof surrounding the aperture, and a surrounding member extending upwardly from the base member to fit around the chimney passing through the roof.
- The base member is adapted to match the shape of roof surface and comprises a panel having a top edge adapted to be positioned on an upper part of the roof, a bottom edge adapted to be positioned on a lower part of the roof. The panel also has two opposite side edges and an opening. The opening is large enough to allow passage of the chimney therethrough.
- The surrounding member extends upwardly from the base member to fit around the chimney. The surrounding member is tubular in shape and comprises a top opening sized to fit around the chimney. The surrounding member also comprises a bottom opening coaxially positioned on top the opening of the panel of the base member. The bottom opening is sized to allow passage therethrough of the chimney.
- The flashing according to the present invention further comprises a joining ring structure. The surrounding member, the base member and the joining ring structure are joined together through fastening means that traverse the base member sandwiched between the joining ring structure and the surrounding member.
- Preferably, the fastening means is a series of spot welds or rivets.
- Thanks to its particular structure, the flashing according to the invention may be installed in a very easy and efficient manner on any kind of shape of roofs, including roofs with different tile configurations.
- In all cases, the installation problems mentioned hereinabove are solved. The flashing according to the invention can be prefabricated in a manufacturing environment rather than be built on site prior to installation. Thus, the flashing according to the invention is very efficient and versatile and can be used in an efficient way on any kind of shape of roof or tile thereon.
- The invention and its advantages will be better understood upon reading the following non-restrictive description of a preferred embodiment of it, made with reference to the accompanying drawings, in which:

The surroundingmember 11 comprises atop opening 29 sized to fit around the chimney passing through the roof and a bottom opening coaxially positioned on top the opening 23 of thepanel 9 of thebase member 7. Preferably, the top opening has a ¼ inch clearance from the chimney, but this clearance can be varied. Of course, the bottom opening must also be sized to allow passage therethrough of the chimney. The rigid surroundingmember 11 maintains required clearances between the chimney and surrounding combustible materials, as well as ensuring the structure's vertical stability. - As shown in
FIG. 8 , the surroundingmember 11 is preferably shaped as a funnel. Thus, itstop opening 29 is smaller in size than its bottom opening. - In as much as, in most constructions, the chimney, pipe or other member that have to pass through the roof, extend vertically and the roof on which the
flashing 1 is intended to be installed for weatherproofing purpose is itself inclined, the surroundingmember 11 has to be oriented at an angle selected as a function of the inclination of the roof. In other words, the central axis of this surroundingmember 11 will be inclined toward thetop edge 15 of thepanel 9 of thebase member 7. - In such a case also, the
top opening 29 of the surroundingmember 11 will be substantially circular in shape and the bottom opening of the surroundingmember 11 will be substantially elliptical in shape and sized to match the size of theopening 23 made in thepanel 9 of thebase member 7. -
FIG. 9 is illustrative of the shape and inclination that may have the surroundingmember 11 as a function of the actual slope or inclination of the roof.FIG. 9 shows the shape that the flashing 1 must have to fit on a roof having a pitch of 8/12 to 12/12. The expression “roof pitch” as used hereinabove refers here to a measurement used to quantify the steepness a roof. It is measured by the rise in inches for each 12 inches of horizontal run. The larger the fraction, the steeper the roof is. Of course, other shapes could be selected depending on the user's needs. - The following Tables 1 to 3 include examples of the dimensions that may have the flashing 1 according to the invention for different roof pitches.
