This invention relates to sheet metal roofing, and has special reference to improvements in lap-joints for sheet metal rooting, Vwhereby the passage through the joints of wat-er, snow and other substances is prevented.
An object of the invention is to provide an improved lap-joint for sheet metal roofing, in which the marginal portion of each of the sheet metal sections that is overlapped by the marginal por-tion of an adjacent section is corrugated to provide adrain groove between upwardly rounded corrugations, and in which a flat portion of the adjacent section spans and bridges said groove and seats upon the upper corrugations at the sides of said groove and forms therewith closed oints substantially preventing the passage of water and other substances into said spanned and bridged groove. To obtain this object, that portion of each sheet metal section overlapping the drain groove in the adiacent section has its edge curved downwardly to correspond with and fit against the correspondinglv curved corrugations of the latter section. while the flat overlapping portion of each sheet metal section extends stra-ight across between the upper surfaces ofthe two corrugations forming the covered drain groove` so as to cover and lea-ve said drain groove unobstructed. The overlapping portions ot' the sheet metal roof sections are pierced bv nails passing through them in a relationship in which the nails pass through the upwardlv curved corrugations of the underseoti on. thus forming nail holes above the bottom of the drain groove only.
Rv this improved construction` I provide an imperforate covered drain `groove having approximately the same unobstructed depth as the depth ot the remaining corrugations of the sheet metal sections, and it is nearly impossible for water and other substances to enter the drain groove to cause the close contact of the upper section with the upper surfaces of the corrugations at the sides of the, drain groove. l
Other objects of the invention will appear from the following description, reference bereao. sciiti no. 433494.-,

Whichy Fig. 1 is a cross-sectional view showing my iinproved'lap-joint construction.
' Fig. 2 is a perspective view.
` All ot the sheet metal sectlons are of dupli cateconstruction, each being long ritudinallyl corrugated to provide a downwardly extended marginal portion 1 having its edge in' thev same plane as the lower surfaces ofthe down-A wardly curved corrugations 2.- Thus,thecor rugations 2 and the edge of the 4marginal portion 1 bea-r against the roof supporting mem-- bers 3.
` All of the corrugations from themarginal portion l to the corrugationii are-alike-as to width and depth; :From the corrugation ,4, each `sheet metal .section Iis. extended to pro vide ai dat portion -terminating ina down.

The ,width of the, en porties "5 is quin to the distance between the crestso the two adjacent.- corrugations7 and.8,' which are ythe first `r`two, 4corrugations. inwardly from ithe marginal portionl of each sheet. s The flat portion 5 thus spans .andbridges the groove 9 formed Vby the corrugation ofVK thefsheet metal between the corrugations 7 and 8. This covers the groove 9 and leaves said groove unobstructed for the freedischarge of water.A The `sheet metalsections are assembled to. form a roof by arranging themin a relation ship in whichthe-lat portions overlap'the corrugations 7 and-8 of adjacent sections to cover and leave unobstructed `the drain grooves The, downwardly.. curvedmar.- ginal edges 6 seatclosely against `the corrugations 8, andthe lat portions 5 seatclose-v ly upon the crests of both corrugations 7 and 8 of the respective sheets; while the downwardly curved portions 10 ofthe corruga-V tions 4 seat closely against the curved edges l. The -lat portionsk 5 andthe crests of the corrugations 7 and 8 maybe provided with registering holes 11 through which nails 12 may be driven. Thus, these nails 12 are at the crests of the corrugations 7 and 8 and leaive unobstructed and imperforate the channe s 9.
These sheet metal sections for a sheet metal roof of the lap-joint type may be manufactured in large quantities at comparatively low cost and expense, because they are of duplicate construction. There is no diiliculty in assembling the sections to provide a roof, since the fitting of the parts 5, 6 and 10 of each section upon the corrugations 7 and 8 of an adjacent section will necessarily arrange the sections in their proper relationship. The holes 11 may beprovided in either one or both overlapping portions, or these holes may be omitted if desired. v
It is now apparent that my invention obtains its intended objects and purposes in an eicient. and economical manner.
What I claim is 1 A' sheet metal roofing section having a plurality of uniform corrugations parallelwith and covering the entire area between the longitudinal edges of said section and having one edge extending downwardly and ter- Vmin'ating yin approximately the same plane with the under sides of the lowest portions of all of said corrugations and having adjacent to and parallel with its opposite edge alfiat portion of a width equal to the distance bef tween the crests of any two` of said corrugations, the marginal ledge of said fiat portion being curved downwardly according to the downward curvature of saidcorrugations,said flat portionY being adapted to seat uponiand span any two` corrugationsfof an adjacent roofing section in a relationship in which the curved portionsA adjacent to saidriiat portion engage closely the curved portions of the corrugationsof the adjacent 'sheet..l
