UNITED STATES PATENT .o1-FICE nooFING Herman Lee Seymour, Jacksonville, Fla., assignor to The Philip Carey Manufacturing Company,
a corporation of Ohio Application December 9, 1929, Serial No. 412,600
3 Claims.
My invention relates to roongs, particularly to what are known as built-up roofings in which sheets of roofing material are applied to a roof deck in one or more layers'cemented together.
5 It is addressed especially to roongs applied to a structure where there is a roof deck and a parapet wall or other adjacent vertical structure requirng ashings. .j
By my invention, I provide a system of ashing that insures against leakage between theroof deck and the wall, maintains the dashing in position, provides for irregularities in wall or deck, overcomesV breakage of the roof at the intersection between a roof deck and adjacent walls, or adjacent angular portions of the structure, is
suiliciently plastic to absorb vibration, compensates for expansion or contraction, and provides a highly eicient iiashing system economical to apply and one that will remain waterproof and watertight.
In the drawings: y Fig. 1 shows the preferred form of my built-up roofing and flashing system applied, withportions removed to clearly show the method of application. y
Fig. 2 shows a modification of a portion of Fig. 1.
Fig. 3'is a modification of a portion of Fig. 1 showing a metal counter iiashing.
Fig. 4 is a section of my counter flashing material.
Fig. 5 is a view of my cave, `outlet or comer flashing block. Y
Fig. 6 is an enlarged view showing the layout of the Vcant strip and the adjacent sheet members.
In the drawings, I have shown my invention as' applied toa wood deck but I would have it understood that same may be applied to any type of deck such as a concrete, or brick, or any type 40 of parapet wall such as concrete or brick, or any other type of deck or parapet wall, or to any roof deck and adjacent wall or structure as the type of such structures do not form any part of my invention.
In the drawings in which like characters or like numerals refer to like parts, 1 is a roof deck, 2 an adjacent parapet wall. Over the roof f deck and extending up the vertical wall is applied a sheet of suitable flexible rooting 3 which may be cemented by bituminous cement or otherwise fastened to the roof deck and permitted to klay up against the parapet wall. As many sheets of suitable roofing may be applied as desired. At the angle between the roof deck and the parapet wall and over theroong, I place a flashing block 4 preferably using a block containing bituminous and fibrous materials preformed to the desired shape and having a plastic like form sustaining quality. This fiashing block may be nailed to the wood deck, where a wood deck is used, by nails passing through the block, the roof sheet and into the deck or may be cemented in place by using bituminous or other suitable cement 5. The flashing block 4 having been nailed, or cemented, or both, in place, Iv then apply over the exposed surface of the dashing block 4, and a portion of the top surface of the rooflng sheets 3 a coating of bituminous or other waterproof cement 13 into which is embedded a counter flashing sheet 6 of felted, bituminous saturated material. 70
This counter fiashing sheet 6 is preferably made by cementing a sheet of bituminous saturated felt to a sheet of woven material such as burlap by an asphaltic or other bituminous cement thereby` providing a strong waterproof 76 counter flashing sheet that may .be stretched without breaking and that will permit movement of the adjacent parts of the roof deck and wall or either oi' them due to contraction or expansion without breaking thiscounter flashing sheet. v This iiasLing sheet shown in Fig. 4 may be made in any suitable way and of any. suitable felts such as paper, wool or mineral felts 7 saturated with bituminous material and having cemented to its surface a sheet of woven textile material such as burlap 9 that has been waterproofed or that may be waterproofed by the cementing material 8 and over this may be applied, if desired, a sanded or similar surfacing 10 as shown in Fig. 4 which is an enlarged cross section of 90 this sheet.
Over this counter flashing sheet 6 is then applied a coating 13 of bituminous material such as asphalt or other suitable cement extending over the counter dashing and on to the roof so as to completely cover all joints and form with the coating on the roof a continuous sheet of waterproof bituminous material. In Fig. 1, I have not covered the counteriiashing sheet 6 with coating 13, having omitted a portion. so as to clearly outline the sheet 6. I prefer to use for this coating 13 a bituminouscement containing a brous material such as asphalt and asbestos bre.
In the drawings for simplicity I have shown but one sheet of roofing material applied to the surface of the roof deck but of course as many sheets may be applied one above the other cemented together and secured, by cement or otherwise, to the roof deck as may be desired. Several plies of counter hing may also he applied if desired. If it were desired, the counter flashing could be extended from a nailing strip 11 in the wall 2 to which it is fastened, as shown in Fig. 2, or from the top of the parapet Wall, being secured under the crown l5, down over the flashing block. In the application of the flashing block 4 it may be, if desired, cemented to the roofing sheet and not to the parapet wall, or to the parapet wall and not to the roof, but on a wood deck I prefer to cement it at both the top and the bottom.
In Fig. 2, I have shown a ilashing block 4 especiallyadapted for eaves or for outlets in which the flashing block nlls, when cemented in place and covered with flashing sheet 6, the angle between the roof deck and the wall and provides an unobstructed passage for drainage for an outlet, shown in Fig. l, or for an eave shown in Fig. 2 by having one or both ends cut so that the end surface I6, shown in Fig. 5 is oblique to the surface l'. The end surface I6 if cut at an angle of 45 degrees to the surface 17, which is to contact with the wall, will', with the next adjacent similarly cut block, form a corner joint, shown in Fig. 1, easy to apply and ready for the counter flashing or roofing sheets to be applied over same.
In Fig. 5, I have shown a detail of the block 4 showing the surface 16 at an oblique angle to the surface 17 and the opposite end at the ordinary angle of 90 degrees. For some purposes I have found it an advantage to provide the portion of the block 4 when made for eave and outlet construction, with the surface lli, connecting the vertical surface 17 and the horizontal surface of the block so as to provide a space for cement and for intimate contact with the roofing sheet that it sets over.
If desired, a roofing sheet material reinforced as shown in could be used for a base sheet of the roof and over this could be applied similar reinforced sheets or ordinary roong material. When a plurality of sheets of roofing are applied cemented in layers on the deck so as to give a roofing of several plies, one or more of the sheets or plies could be cemented on to the top surface of the flashing block and the counter flashing 6 cemented on to the roofing sheets so affixed to the top of the block In Figure 6, I have shown a roofing in which the two layers of felt roofing are shown cemented to the deck, one layer of which, at the parapet Wall, is turned up and contacts with the cant strip 4, and the upper layer of which is turned to overlap, contact with, and is cemented to, a portion of the upper surface of the cant strip 4. In this figure the cant strip is shown as cemented to the upper surface of the lower layer of roofing felt and to the parapet wall by asphalt 5. The flashing 6 is alixed to the parapet wall above the cant strip and extends down over, and is cemented to, the surface of the cant strip at the upper portion, and overlaps and is cemented to the second layer of roofing material.
In Fig. 3, I have shown a modification using a metal counter flashing 18, ilxed to Wall by screws I9, so arranged as to provide an apron 20 ove:` the hashing sheet 6 and a trough 2l into which may be placed any suitable waterproof cement or filling. If desired, the ordinary metal flashing having one edge embedded in wall and an apron extending down over the flashing sheet 6 could be used. In the application of my flashing system, the adjacent blocks may, if desired, be provided with any means to hold them in register and may be cemented together by a suitable cement 5 to form a watertight joint as shown in Fig. l when-the corner is formed.
I claim:
