2._. A real Guarantee To be more than amerescrap of paper, a guaranteemustbeabso lute-and backed by a concern able and willing to make good. The General's guarantee on CERTAIN-TEED Roofing is not only absolute; it is backed by the world's largest roofing and building paper mills, making one-third of all the roll roofing made in America. The guarantee is for 5, 10, or 15 years, according to ply (1, 2, or 3). This guarantee is possible because the roofing is thoroughly saturated with the General's own blend of soft asphalts, and then coated with a harder blend which keeps the inner saturation soft and prevents drying-out. CERTAIN-TEED is made in rolls; also in slate-covered shingles. There is a type of CERTAIN-TEED for every kind of building, with flat or pitched roof, from the largest sky-scraper to. the smallest out building. CERTAIN-TEED is sold by responsible dealers all over the world, at reasonable prices. General Roofing Manufacturing Company World's Largest Manufacturers of Roofing and Building Papers.
