-4 Claims. (o1. 108-13) The invention relates to roof structures.
The general object of the invention is to provide an improved roof structure in connection with that type of roof using a composite roofing material having a flexible fibrous backing layer, and a thin sheet metal facing layer. More particularly, one of the objects of this invention is to provide an improved. seam connection between strips of roofing material wherein the backing material extends over the metal joint between the strips to protect the same and prevent heat leakage along this seam and to provide an improved anchorage connection of the strip of roofing material to the roof frame members wherein the attaching nails pass through several layers of backing material in addition to the metal lug strips.
A further object of this invention is to provide a roofing structure in which the exposed parts of the strips of metal facing are provided with corrugations or score lines running normal to the ridge pole of the roof and adapted to reinforce the roofing materialayet permit it to be readily applied to the roof by unrolling it from a roll and which corrugations or score lines will permit expansion and contractions lengthwise of the roof of the portions of the roofing strips between anchoring connections.
A further object of the invention is to improve the roof structure more particularly shown and described in the prior U. S. patent to- John H.
Wahl and Paul H. Doe, No. 2,043,271, dated-June 9, 1936.
The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.
In the drawings:
Fig. 1 is a perspective view of a portion of a piece of roofing material that may be used in forming the roof structure embodying the invention;
Fig. 2 is a detailed sectional view taken on the line 2-2 of Fig. 1;
Fig. 3 is a detailed vertical sectional View through two strips of roofing material as initially positioned for forming a joint between them;
Fig. 4 is a view similar to Fig. 3 showing the metal facing strips partially joined together;
Fig. 5 is a view similar to Fig. 4 showing a section through the adjoining strips where an anchor or lug strip occurs;
Fig. 6 is a View similar to Fig. 5 showing the metal facing strips and an anchor strip fully joined;
Fig. 7 is a detailed vertical sectional view through a pair of joined or seamed strips with 55 such as asphalt cement. is corrugated and is substantially coextentive in the upper strip folded over to form the next course and showing the anchoring lath;
Fig. 8 is a perspective view showing parts of a roof structure in its completed form and other parts being laid.
'The roofing material used in connection with the roof structure embodying the invention is preferably the material shown, described, and claimed in my copending application Serial No. 384,862, filed March 24, 1941 and is of the composite type comprising a flexible fibrous backing sheet or layer I6 of paper or fiber board and a thin metal facing sheet or layer I I preferably thin sheet copper of two-thousandths to eight-thousandths of an inch thick, which sheets are bonded together under pressure with asuitable adhesive, The backing sheet I6 width with the facing sheet I I which is also corrugated or scored as determined by the corrugated backing except for marginal portions I 2 which are not adhesively secured to said backing sheet. The composite material above described is formed .as'a web or strip that may be rolled up into lengths sufficient to extend for any desired distance lengthwise of the roof.
In laying a roof embodying the invention with roofing material of the type above described, a roll of the material is unrolled lengthwise of the roof to bring this web or strip of material down flat against the roof boards or framing F with the backing layer on the inner side. Another roll of the material, to form the second course, is unrolled on top of the first strip with the backing layer of the top strip thus provided uppermost as shown in Fig. 3 in which the marginal edge portion I3 of the backing strip of the second course strip is bent upwardly to a position to expose the marginal edge portions of the adjoining metal facing strips of both courses whose marginal portions are seamed or interlocked together by first bending over these parts as shown at I4 to form a hook or single overlap into which at suitably lengthwise spaced intervals the hooked ends I5 of metal anchor lugs I6 may be inserted as shown in Fig. 5. Thereafter, the parts thus joined may be further interlocked with each other by 'folding them over again to form a double overlap joint I"! as shown in Fig. 6. For anchoring the adjoining edges of the two courses together the anchor lugs I6 are bent down over the marginal portion I3 of the backing layer of the first course, and the marginal portion I3 of the backing layer of the second course is then laid down over the tops of the anchor lugs I6 along this joint, thus providing three thicknesses of material through which the fastening means, such as the nail I8, may be passed to anchor adjoining edges of roofing courses to the roof base or foundation F and also providing an additional layer of heat insulating material over the seam between the twocourses.
In order to provide for lengthwise contraction and. expansion in these strips or courses, the total contraction and expansion of the strip is split up into a number of smaller fractional amounts by anchoring the strips firmly to the roof by a series of transversely spaced cleats or slats H which are arranged in staggered relation for adjacent courses and which have the efiect of producing a top roof surface comprising a series of elevations and depressions extending normal or at right angles to the ridge pole of the roof. These slats or cleats 19 are of a length slightly greater than the width of the course strips and, it will be noted from Fig. '7, are arranged to have their lower ends clampingly engage over the locked seam I1 and the marginal portion l3 of the backing strip forming the second course with the nail l8 passing through this strip back of said seam as shown in Fig. '7. The upper end of each slat extends under the backing material of a laid course and the backing material of a new course and is se-- cured to these layers and to an anchor lug I5, disposed beneath the two layers of backing material, and the roof by a nail 20. Thus the lengthwise expansion and contraction of the roofing courses is localized between the cleat anchorages with the result that the amount is not so great that it cannot be adequately handled within this area with the wave-like formation assisting in permitting any expansion and contraction between anchorage points to readily occur further assisted in the present invention by the corrugated or scored form of the metal facing, not shown in Fig. 8 but shown in Fig. 1. Thus lengthwise contraction and expansion is fully taken care of, and as the strips are relatively narrow, for example twelve inches in width, and there is a certain slack available at the seams, their expansion along their width may also be taken care of due toinclining of the surface from the high jointed lower end to the flat surface of the roof as shown in Fig. 8. Slats l9 may also be arranged under the first courseas indicated in Fig. 8 and as also shown in the above-mentioned patent with the lower end of this course folded about a wooden lath 2| which is nailed through the inner edge of the roofing course to the bottom edge of the roof base F.
I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.
What I claim as my invention is:
l. A roof covering composed of a plurality of narrow thin metal strips and backing layers of fibrous material substantially coextensive in width with said strips running longitudinally of the roof, the adjacent edges of the metal strips being folded over between the adjacent marginal edges of the backing material to join and interlock said metal strips, sheet metal anchor lugs interlockedat spaced intervals with the folded over edges of said metal strips, roof-fastening means passing through the marginal edges of said backing material for each metal strip and said anchor lugs, and means for localizing the longitudinal contraction and expansion of said metal strips.
2. A roof covering composed of a plurality of narrow thin metal strips transversely corrugated for a portion of their width and having uncorrugated marginal portions and a backing layer for each metal strip of corrugated fibrous material substantially coextensive in width with said strips and running longitudinally of the roof, the marginal portions of adjacent metal strips being folded over to join and interlock together between adjacent marginal edges of the layers of backing material for said strips, anchor lugs interlocked to the interlocked metal strips and extending between adjacent marginal edges of said backing material, and fastening means securing said lugs and marginal edges of the backing material for said strips to the roof.
3. A roof covering composed of a plurality of narrow thin metal strips transversely corrugated for a portion of their widths and having uncorrugated marginal portions and a backing layer for each metal strip of corrugated fibrous material substantially coextensive in width with said strips and running longitudinally of the roof, the marginal portions of adjacent metal strips being folded over to join and interlock together between adjacent marginal edges of the layers of backing material for said strips, anchor lugs interlocked to the interlocked metal strips and ex tending between adjacent marginal edges of said backing material, fastening means securing said lugs and marginal edges of the backing material for said strips to the roof, and means also secured by said fastening means in clamping engagement with the interlocked margins of the metal strips and the margins of the backing material for said strips to clamp said parts to the roof.
4. A roof covering composed of a plurality of narrow thin metal strips transversely corrugated for a portion of their widths and having uncorrugated marginal portions and a backing layer for each metal strip of corrugated fibrous material substantially coextensive in width with said strips and running longitudinally of the roof, the marginal portions of adjacent metal strips being folded over to join and interlock together between adjacent marginal edges of the layers of backing material for said strips, anchor lugs interlocked to the interlocked metal strips and extending between adjacent marginal edges of said backing material, fastening means securing said lugs and marginal edges of the backing material for said strips to the roof, and means also secured by said fastening means in clamping engagement with the interlocking margins of the metal strips and the margins of the backing material for said strips to clamp said parts to the roof, said means also extending widthwise of the strips at spaced intervals to provide for depressions and elevations lengthwise of the metal strips along each course of the roof and thus provide for longitudinal expansion and contraction of said metal strips.
