freder/c/f A L)Y1/7 der/: BY g 7 Patented Sept. 18, 1951 U N `:l TED .S T l OF F I CE ROOFING Fredericklk Sunderhauf, Rutherford, N.`J.,"as vsignor to Reynolds Metals Company, Richmond,
Va., `a corporation of Delaware Application January 6, 1948, Serial No. `'705 A "l =Thefpresent `invention relates to -atype of roofingadapted yto be handled andapplied 'from rolls, and which may be readily laid longitudinally on a roof, interlocking of contiguous strips of the roofing being obtained bymarginal seaming. My
roofing is so `formed-as to enable its manufacture from relatively'light `aluminum or other light metallic sheets, and the folding thereof 180, in a'seaming fold, without fracture even when the metal is of such character -as not to resist `such fracture'in usual fold-seaming. The roofing ernbodies, in `its `preferred form, `a ribbed facing which extends across the seaming lfold lines and strengthens vthe saidlines, and at the saine time,
provides Ya desirable rigidity to the roof-ing as a whole,` together `with a pleasing texture. As statedpmy roofing, at its lines of seam-forming fold is of special formation, not only to enable safe folding -intheuse of relatively fragile metallic sheets, but to provide, incidental thereto, registration abutments for foontiguous sheets.
The invention is particularly applicable `to light Weight aluminum sheets of which sheets `having a 'gauge of .010 is an example, and with such sharp seaming folds Vas to `fracture vcertain of the sheets in the absence of my fold-line formation. `Inasmuch as aluminum'and aluminum alloys are 4ideal roofing materials because of vease inhandling dueto lightness uin weight, 4its lower labor cost in application, itslower maintenance cost due to elimination of required painting, its reflection of the greater part of radiant heat in summer, and its generally long life, my invention affords a major extension in the use of light aluminum sheet or strip in the roofing field.
The invention will be described with reference to the accompanying drawings, in which:
Figure 1 is a plan view, broken away, showing part of a metallic sheet or strip of my invention;
Figure 2 is a transverse vertical section taken on the line 2--2, Fig. 1, and hence through one of the seaming-fold lines;
Figure 3 is a fragmentary view in perspective showing an end area of a roofing strip, as from a roll of my roofing, applied to a roo-f shown in dotted lines so that it projects over an end and a side of the roof, the roofing being folded under the roofing side ready for nailing;
Figure 4 shows a succeeding roofing strip placed in initial position and temporarily nailed down ready for folding over of a seaming flap carried by the iirst sheet at its upper margin;
Figure 5 is a view similar to Figure 4 showing the last named fold nailed down and a second strip or sheet ready for folding upwardly 180;
1 Claim. (C1. `10B-13) whole being indicated at 'l "Figure Gris a viewsimilarto Figure 5 showing the Asecond sheet folded upwardly and the sheet at the corner of the `roofing tucked `preliminary to "folding the seamed edges of contiguous `roofing sheets orstrips over and`- under the edge` of the roof for nailing thereto;
Figure 7 is a View similar to Figure 6 showing three of the roofing sheets or strips in nal posi-- tion;
Figure 8 -is a 4fragmentary perspective view showing the ridge area of `a roof, `a plurality `of my roofing sheetsor strips being shown in section;
Figurea ,is a 'perspective View of a suitable ridge cap.
v*Referring to the drawings, andparticularly Figures '1 and 2, itwill be seen that my roofing consists of sheets or strips, and preferably la roll of strip whichhastwoireversely formed marginal areas, in that one margin is inwardly bounded by an 'upwardly directed channelY rib Ix, whereas the second margin is inwardly bounded by a down-turn channel-rib 11cm, the roofing as Aa The roofing is faced with ribsfwhich extend across the channel ribs, in mypreferred form of the roofing.
Itis highly desirable that `my roong be made of aluminum strip of such `light gauge, say, .010" as to berolled and handled in that form. Not only may a given `:roof `surface be Acovered as quickly with my aluminum strip or sheet roofing as with composite rolled roong now generally sold and incorporating asphaltic materials, but my roofing will be substantially lighten, of far better appearance and long life, with substan tially no cost of maintenance.
As indicated in Figure 4, the seaming-fold channel ribs are of substantial depth and inwardly bound the margins of my rooflng strip or sheet. When the roof covering is started at the eaves or base of the roof, as customary. a roll of my roong may be placed so that it may be unrolled from edge to edge of the roof in such manner that at the edge of the roof, the downturned channel rib I will lie immediately above the roof edge, whereas the upturned channel rib lx will be above the same. Also the end of the rooiing strip may project beyond the edge of the roof.
With an initial strip of the rooilng in position at and over the roof edge, the lower margin a may be bent down vertically and thence turned under the roof for nailing as shown in Fig. 3. After nailing the initial roong strip the second strip is applied.
memes As shown in Fig. 4, the second strip is invertedv `in the sense that it will initially lie with its normal under-face exposed. Its channel rib Imm will be downward and its rib la: will project upwardly, an edge of said second strip abutting the upstanding channel rib la: of the initial roong strip.
When the two strips lie in the position of Fig. 4, the second and overlying strip may be tacked rearwardly of its channel rib lzc, as by the tacks 2, these tacks passing through the initial under-Y lying strip and serving to hold the assembly in,
The next connection with the roof surface 3. step will Abe the folding of the projected upper margin of the lower strip to the position of Fig; 5
'and the nailing thereof down to the roofing 3 by nails which preferably are spaced approximately four inches apart. The said folding involves movement of the metal approximately 180. y
` of said thickness.
With the assembly of strips as shown in Fig. 5, the upper strip is swung to the position of Fig. 6 ready to receive a third strip and continuation of -the method of laying successive strips, as before.
- At the corner of the roof the metal may be tucked inas shown at 5, Fig. 5, and the projected strips at the end of the roof may be folded down and'thence under the edge of the roof as indicated in Fig. .'7, ready for nailing.
lAs shownin Fig. 8, one of the uppermost strips is bent over the`ridge,l and at the opposite side of the latter a strip is bent back upon itself at the margin thereof, the assembly being nailed down as by the nails 1. The ridge can be capped with a ridge piece 8, which may be of aluminum, although thisv is not essential.
It will be understood that various modifications may be made in the form and arrangement of the elements constituting the embodiment of thc invention illustrated in the drawings, without departing from the spirit of the invention, For example the metallic strip may be unitary or in lamination with lone or more non-metallic webs. 4 Y
what I emmene desire to secure by Letters Patent is as'V follows:
A methodpof applying a roof covering formed as a metallic strip having opposed longitudinal margins, one of the margins being bounded by deformation'of the metal into a rounded channel rib having'aheight. above the face of the metal substantially greater than the thickness of the metal, said kstrip having its opposite margin bounded by a like channel rib projected in a direction opposite that of the rst named rib, which method consists in laying a first strip upon a support with the rib of its channel.. rib projected upwardly, laying a second like strip over the first strip with its longitudinal edge abutting the outwardly directed channel rib of the overlying strip and with the rib of its` channel rib projected upwardly, thence vfolding overl the margin ofthe first strip to abut the margin of the second strip adjacent the rounded'projected rib of the latter, tacking said margins of the superposed strips to the underlying support, and thence folding over the second strip into abutment with said support, whereby as to each strip the metal is moved on a plurality of linear areas of Yfold within each channel rib to provide distribution of the folding movement of the metal to prevent yfracture thereof and thefolding is in the direction of projection of each channel rib.
