5 Claims, 12 Drawing Figures PATENTED SEP 1 6 I975 SHEET 3 I]? 5 INVENTOR. JOSGFH F ENE/56L ROOF FLASHINGS FOR USE WITH ROOF PLANKING 1 This is a continuation "of' application' Ser. No. 101,982, filed Feb. 28, 1970 and -now abandoned, which was acontinuation in part of applicantsapplication Ser. No.885,148 filed Dec. 15, 1969 and now US. Pat: No. 3,626,439.

BACKGROUND OF THE INVENTION The field of the invention is roof flashing. Flashing is commonly made up of sheet metal such as galvanized steel, copper, orother metal which may be further treated to reduce corrosion. More recently flashing has also been made from sheetsof plastic such as polyvinyl chloride. I

With increased labor costs there is continuing interest in developing roofing systems which are more quickly installed than wooden or asphaltic shingles. Many steps are involved in applying the typical roof to the rafters ofa'building. First, sheathing is nailed to the rafters. Such sheathing usually is in the form of plywood sheets, or 1 by 4 boards laid-several inches apart. Then, a layer of felt,-such as poundfelt, is laid over the sheathing. .F-inally, individual shingles, usually asphalt-or shake,- are nailed to the underlying materials, one at a time.

, 1 Roof construction of this nature suffers from a number of disadvantage in addition to the high cost of the various materials and installation. Such shingles do not seal themselves-on top of each other because both sides usually are rough. They tend to shrink apart and curl. Only the felt, which .serves as a membrane, prevents leaking; however, .the nails which hold the shingles puncture the felt giving rise to leaks. In order to facilitate more rapid installation, minimum;and insufficient nailing isa common practice. This gives rise to an unsturdy construction. Also,'in the eventof rain anda slight wind, water is easily blown underneaththe shingles and under. severe wind conditions the shingles can be blown completely from the roof.

vOther types of roof construction involve tar paper and rock, ceramic tiles, aluminum and so forth. The tar paper and rock'construction is relatively cheap but is less durable than shingle roofs-becausethe tar paper deteriorates from exposure to the sun. A ceramic tile roof. requires a very heavy rafter and sheathing structure, and still requires a membrane which is punctured with nails which hold the furring to which the tiles are secured. Aluminum shingles have most of'the constructional disadvantages of wood shingles plus the fact that they are extremely fragile and cannot be walked upon after installation.-

. Turning again to prior art shingle, paneor plank type roofs, several have been devised employing various types of joints between-roofing units. Each involves certain deficiencies. Typically, no provision is made for correction of accumulated error, without disturbing the integrity of. the joint. when laying the various courses a of the roof units. Subsequent shrinkage of the material renders the joint ineffective from both a structural and water proofing standpoint. Other roofing configurations have very complex joints, butthey involve water leakage problems and costly manufacture procedures and equipment. In many instances, the securing nails are exposed thereby giving rise to ultimate corrosion as well leakage problems. Others must beinstalled from found the roof ridge down which causes a problem at the cave line. Examples of patents illustrating joints similar to those which have been used in roofing construction are in US. Pat. Nos. 492,736; 2,013,218; 2,241,642; 2,390,087 and 2,659,938.

' During the construction of a building, various joints must be made water tight. These joints exist at the intersection of roof planes and around chimneys, vents, dormers and the like. Applicants parent application filed Dec. 15, 1969, Ser. No. 885,148 describes a new roof construction together with means for forming a water proof joint at the roof peak and the disclosure of this application is incorporated by reference herein. Various means have been devised to waterproof valleys which occur when two different roof planes intersect to form an angle less than Commonly a length of creased sheet metal is placed lengthwise along the valley and the shingles are subsequently laid over each edge of the sheet. When two roof planes intersect and form an exterior angle greater than 180, a roof hip is formed. These hips are commonly waterproofed by nailing shingles over the hip. These shingles are cut to form a joint composed of the longitudinal edge of one shingle with the underside of its abutting shingle.

1 The roof joints around chimneys and dormers are most commonly waterproofed by pieces of sheet metal together with a layer of mastic. The sheet metal underlies the shingles near the chimney edge. Similarly, vent pipes are commonly waterproofed by placing a flat metal sheet over the vent pipe which extends above the -roof plane. This metal sheet is then sealed to the vent pipe and shingles are placed over the extending edges of flat sheet.

While these prior art methods may be adapted for use with roof planking such as that disclosed in Applicant's parent application, the present inventive concepts involve new roof flashings which areparticularly useful with roof planking and result in a considerable labor saving together with improved waterproofing characteristics.

SUMMARY A novel and easily applied family of flashing members has been devised which forms a waterproof joint at discontinuities in roof planking. The term roof planking is used herein to refer to roofing of the general type disclosed in Applicants parent application. This general type of roofing is made from generally flat planks or-long boards. These planks are distinguished from common wooden shingles in that they are substantially longer in the direction parallel to the eaves and further they are substantially thicker. Roof planking may have decorative grooves cut in the outer surface and may be .pre-coated with a weather and fire proofing coating. The roof planking preferably is thick enough along its lower edge so that nails, staples or the like may be driven into the edge without splitting the planking.-

The family offlashing members of this invention have a generally flat roof-mating surface which lies along the surface of the roof planking. These members may also have reinforcing sections formed along one or two edges ofthe flashing. They also have a downwardly extending section which overhangs the lower edge or face of the-roof'planking and permits the driving of nails, staples or the like into the lower edge of the roof plankingso as to eliminate, leakage problems occasioned by the fasteners need. These flashing members are modified depending upon the particular shape ofthe joint to be sealed.

-In some instances the flashing members are bent or initially formed toconform to the slope of the particular roof to be sealed.- It. is preferablerthat one edge of the flashing abut against a head of resilient material located under the overhanging edge of the roof planking.

Thus, the upper edge of the flashing members has no verticallyextending section so that it may fit-up? under the overhang. Y

Accordingly. it is a principle object of the present invention to provide a new flashing construction;

It is another object of this invention .to provide a novel roof flashing whichmay be applied to roof valleys formed from roof'planking.

Another object of this invention is to provide .roof flashing for use over roof hips formed from joints in roof planking.

-It is yet another object of this invention to provide chimney and dormer flashings for use with roof plank- It is yet another object of this invention to provide vent flashings for use with roof planking. bent These and other objects and features of the present inventionwill become better understood through a BRIEF DESCRIPTION, OF THE DRAWINGS FIGS. la. lb, I and 1d are perspective views of the roof flashing of the present'invention as applied to an opening in roof planking.

FIG. 5 is a partial perspective view ofthe valley flashing of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Turning now to the drawings, and particularly to FIG. la there is shown a portion of a roof formed from roof planking which is described in Applicants parent application Ser. No. 885,148 which is incorporated by reference herein. Briefly, the roof planking is formed from longitudinally grooved planks which come in various lengths but a typical length would be feet. These planks indicated as 10, ll, 12, 13 and 14 in FIG. la may be applied directly to the rafters l5 and 16 of a building or other enclosure. Each plank typically is manufactured one foot wide and is of wood, which may either be solid, laminated as in plywood, or other construction such as that made from wood chips and the like. The upper surface of the plank may be textured to simulate a plurality of shingles or shakes as illustrated by numeral 17 in FIG. la. Joint drain clips 18 are inserted to prevent leakage at the end joints between planks. These clips are hammered into end grooves such as groove 19 formed in each end of the planks.

TheshingIes-may becolored and firc-proofed at the time of manufacture orafter construction is complete. Any suitable type of decorative and protective finish may be-applicd but a sprayable concrete emulsion coating manufactured. by Concrete Emulsion Company, Los Angeles. California isparticularly effective.

The planking'is cut to form an opening around the chimney, dormer or the like. Flashing members of the shape shown in FIG. 10 are used to form the flashing which is parallel to the rafters. This member may be made from metal since it is thus easily bent during installation on the job site as described below. The metal may be copper, lead, galvanized iron, zinc, tin, aluminum or any metal possessing the characteristics of weatherability and reasonable cost. It would be possible to form this flashing from a plastic such as polyvinyl chloride which can be deformed by heating, bending and cooling.

The flashing member 20 shown in FIG. IC has a vertical wall 23, a horizontal section 24', a second smaller vertical section 21 and a downwardly extending section 22. Section 21 gives additional strength to the member. Section 22 is provided with one or more holes for nailing to the planking. The flashing may also be made without holes and the nails are then driven through the metal. This is particularly useful-for soft metals such as aluminum.

In orderto cover an opening, a first flashing member 25 is cut to remove a portion of the vertical wall 23 dependent upon the distance of the opening from the end of the lowest plank through which the opening extends. This distance is shown by the letter a in FIG. la. The vertical wall section 23 and the horizontal section 24 surrounds the lower opening of the plank 10. The end of the horizontal section 24 abutts against the bead of resilient material 26 which is located underneath the lower edge of plank 11. A bead of mastic material may be placed under the horizontal section 24 to further decrease any chance ofw'ater' from leaking under the flashing. Only a small amount of mastic is needed because of the relativelysmooth even surface of roof planking. One or more nailsmay be driven through downwardly extending section 22 into the lower extending side of plank 10. Similarly, flashing members 20 are placed over planks ll, 12 and 13. A cut and bend is made in the last or uppermost flashing member which in FIG. la is placed on plank 13. The cut and bent flashing member is shown in FIG. 1d where the distance of the cut is determined by the distance from the upper end of the flashing member to the uppermost end of the opening. This distance is indicated by the letter b in FIG. la.

A length of metal or plastic flashing 27 is next laid across the upper side of the opening. This piece is preferably lent so that the vertical wall 28 is vertical when the bottom section 29 is placed against the roofing surface. This member may be bent on the job site by means commonly used in the prior art installation of flashings such as with a board and mallet in the case of metal flashing or by heating, bending and cooling for plastic flashing. The corner 30 is then bent at the dotted line to secure it to the flashing member on plank 13. A rivet may also be placed through an appropriate hole drilled beneath the bent portion. A strip of flashing material 31 is next placed under plank 14. The width of this section is determined by the distance from the end of the smaller'vertical section of the flashing on plank 13 to the bead of resilient material of plank 14. This strip of flashing material overlies flashing 27 and pre vents any leakage of water under flashing 27. E

A lower flashing member 32 has a vertical wall 33. a horizontal section 34 and a downwardly extending section 35. The end section of lowerflashing member 32 is shown in FIG. lb and has a'bent section '36which permits attachment to the lowest-flashing member shown in FIG. In on plankl0.-Once again the particular angle between walls 33 and 34 is dependent upon the slope of the roof and thisangle may be formed or altered at the job site. The lowerflashing member is secured to the lowest side flashing member by one or more rivets shown in FIG. Iu as 37 and 38. The portion of the flashing which is not shown in FIG. la is similarly treated except that the side flashing members are formed in a mirror image configuration. The flashing is completed by placing an overlap flashing 40 .over the side flashings 20. This overlapping flashing is most readily secured in a chimney bysawing a kerf in the chimney with a carbide saw parallel to the upper vertical wall of the flashing members. This overlap flashing may then be secured by nailing through holes 41 or by the use of an appropriate adhesive. The flashing members may be pre-painted or sprayed on the job.

Turning now to FIG. ;2, there is illustrated in FIG. 2a the application offiashing to a bermuda-type hip shown in the drawing near the roof ridge. section of hip flashing is shown in FIG. 2b; The flashing has two small vertical walls and 51 which add structural stiffness to the flashing. One of the two downwardly extending sections 52 is shown in FIG. 2b and contains ahole for a nail or the like.

The roof planking members 53 and 54 are first secured to the roof rafters and a buttjoint is formed at the intersection. The flashing piece is then placed over this joint as more clearly seen in FIG. 2:! over the joint between planks 55 and 56. The flashing is then secured by driving a nail into plank 56 through the'hole in the downwardly extending section 52 The flashing fits under the extending portion of the planking. This is shown in the broken away portion of plank'SS where the flashing covering the joint between 53 and S -I is shown abutting against the resilient member 57 which forms a portion of plank 55. The use of mastic is not necessary for this flashing but can be used to'provide additional insurance against leakage if desired. The method for joining the flashing over the roof ridge is described below.

Turning not to FIGS. 3a and3h there is illustrated the flashing of the present invention over a shingle type hip. Once again a butt joint is'formed between the intersecting rows of roof planking such as planks 60 and 61. Starting at the lowest plank in the hip'and working upwardly, a cap locking strip such as those shown in FIG. 3/7 and indicated by reference characters 62,- 63 and 64is nailed over the hip joint of the lowest plank. This cap locking strip is-formed from two lengths of wood 65 and 66 and may be joined atthecenter by a strip of water proof tape such as that sold under the name Tedlar. The inner edges of thestrips 65 an d'66 arc tapered as shown at 67 and 68 to permit installation over hips with different angles. Aapiece of shingle hip flashing shown in FIG. 3b-as 69'is then nailed over the lowest cap locking strip by driving nails through holes 70 and 71 into the ends of the-cap locking strip. The next cap locking strip is then nailed to thc=.next plank intersection and this similarly is covered with another shingle hip flashing piece.

The roof ridge is similarly first covered with a cap locking strip which may have a-waterproof tape such as that sold under the name Tedlar along its joint. This cap locking strip is attached by nails or adhesive to the uppermost planks. A layer of mastic may be placed at the end of the cap locking strip and the end cap 72 is water readily drains away from the hip flashing.

Turning'now to FIGS. 4a through 40 there is shown the novel vent flashing of this invention. Whereas normal vents are extended above the roof line prior to the Ishingling operation. the vents of the present invention are terminated below the roof line. A length of flexible venting is then attached to the upper end of this terminated vent and the other end of the flexible venting is attached to the novel vent and flashing of this invention. This permits the vent to be located in the middle of an'existing-plank rather than the arbitrary location resulting from normal prior art venting methods.

The flexible venting is indicated by therefcrence character in FIG 41. and may be plastic or steel flexible tubing whichmay be attached to both the upper end of the lower vent, now shown. and the section of vent 83 which will extend through the roof by a clamp 82. Various types of clamps are-useful for this purpose andany elampwill form a secure bond betweenthe flexible venting and the flashing vent may be used. The

flashing around the vent is shown most clearly in FIG. 4b where 84 and 85 are vertical sections which add structural strength to the flashing and the downwardly extending section 86 permits attachement to the grooved plank 87. This attachment may be carried out by driving. nails 88 through holes 89 into plank 87..l'he

flat portion 90 of the flashing has a hole therein throughwhich the vent section 83 is attached such as by welding or appropriate adhesives shown by reference'charactcr 91 in FIG. 41'. Any attachment means which will provide good structural strength together with a-leak-free bond may be used at 91. The method of installing the vent and attached flashing is shown best in FIG.- 4b where an oversized hole 92 is cut through plank 87. This hole is shown as an oblong in FIG. 412 but this'could also be an oversized circular hole. The purpose of having the hole larger than the vent piece is to permit an upward sliding of the flashing under the groove in plank 93 shown in FIG. 4a. The amount of oversizing is not critical but should be at least about 3/4 of an inch to permit the vent to be dropped in the hole and then slid upwardly against the gasket 94 of plank 93. In order to prevent lateral waterleakage two beads of mastic material 95 and 96 should be placed along the width of plank 87 prior to dropping the flashing into the opening 92. It has been determined that 26 gauge steel is sufflcient to form the flashing vent 83. I

Turning now to FIG. 5. there is illustrated the flashing of the present invention as applied to a roof \alley formed by the intersection of two rool' planes. Once again. the roof planks such as 100 and IOI are attached to the roof and the ends of these planks are cut on an angle to form an abutting joint. The valley flashing 102 has two smaller vertical sections 103 and 104 to give added structural strength to the flashing. It also has two downwardly extending sections 105 and 106 each of which has two holes therein for driving nails through the flashing into the planking. A bend is formed at 107 and this bend is dependent upon the pitch of the roof to be covered, the more steeply pitched roof requiring a greater bend. in order to apply the valley flashing, a strip of mastic 108 is applied to the upper surface of plank 101 and a second strip 109 of mastic is applied to plank 100. This mastic may be applied in approximately pencil diameter thickness and prevents lateral water leakage at the valley. Next, the flashing 102 is placed over the intersection of planks 100 and 101 and then pushed upwardly against the gaskets which underlie the planks above 101 and 102. This feature is best shown in the cut-away portion of plank 110 where valley flashing 111 abutts against gasketing material 112 which is attached to the underside of plank 110. The valley flashing is then secured by nailing through the holes in the downwardly extending sections 105 and 106. It is necessary that the roof planking be smooth enough so that a layer of mastic can form a waterproof seal between the planking and the flashing. The normal decorative grooves which are illustrated in the drawings and described in Applicants parent application do not inhibit the use of this flashing since the mastic may be applied in a line parallel to and not crossing a groove.

Note that there is a V-shaped opening between downwardly extending sections 105 and 106. It is preferable that this opening be covered by a small rectangular strip 113 which can be adhered to the underside of sections 105 and 106.

Sheet metal such as galvanized steel, copper, aluminum, hard lead, zinc, tin and the like may be used in the practice of the present invention. Likewise, it is possible to use formed plastic such as polyvinyl chloride, but, when this is done, provisions must be made to permit the bending of the plastic. This may be accomplished by warming the plastic in the area of the bend and then cooling the plastic after it has been bent the desired amount. When metal flashing is used, it is desirable to coat the exposed portions of the flashing with appropriate weather-proof coatings. One particularly effective weather-proof coating is a concrete emulsion sold under the name by Concrete Emulsions Company, Los Angeles, California. This coating may be done either before or after application to the roof.

The thickness of the flashing is dependent upon the particular material from which the flashing is constructed. For instance, when the flashing is galvanized steel, a thickness of 26 gage has been found to be satisfactory. In general. the flashing thickness should be about the same as that used in prior art flashing. While the flashing described herein is particularly effective with the roof planking described in Applicants parent application, it may also be used with any other roof planking which has the following characteristics. First, the roofing surface should be relatively smooth, that is smooth enough so that a bead of mastic will form a water tight seal with the flashing. Secondly, the roofing material should have periodic vertical surfaces into which the flashing material may be nailed. Thirdly. the roofing material should have a strip of gasket material or other soft material located at or beneath the overhang of each plank.

The present embodiments of this invention are to be considered in all respects as illustrative and not restrictive. the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims therefore are intended to be embraced therein.
