The balance is "scattered'' among 39 other manufacturers. Each year CERTAIN-TEED rolls up a strikingly increasing number of advocates, because it is coming to be recognized as the most efficient covering for all kinds of build ings, with either flat or pitched roofs. CERTAIN-TEED is clean and sanitary, costs less to buy, less to lay, less to maintain and less per year of life. It is guaranteed for 5, 10 or 15 years, according to ply (1, 2 or 3). It actually lasts longer. CERTAIN-TEED is made of the best quality of roofing felt, and is thoroughly saturated with the General's own blend of soft asphalts, which keeps the inner saturation soft and prevents the drying-out process so destructive to the ordinary roofing.
