oo2s <br /> ROOF PITCH AND EXPOSURE: Handsplit shakes should be used on <br /> roofs where the slope or pitch is sufficient to insure good drainage. <br /> Minimum recommended pitch is 1/6th or 4in-12(4"(101mm)vertical <br /> rise for each 12" (305mm) horizontal run). Maximum recommended <br /> weather exposure is 10" (252mm)for 24" (610mm)shakes. <br /> ROOF APPLICATION: Along the eave line,a 36" (910mm)wide strip <br /> of roofingfelt is laid overthe sheathing. The beginningor startercourse <br /> at the eave line should be doubled. After each course of shakes is � <br /> applied,an 18"(455mm)wide strip of roofing felt is laid over the top <br /> portion of the shakes and extending onto the sheathing, with the <br /> bottom edge of the felt positioned at a distance above the butt equal <br /> to twice the weather exposure. <br /> FASTENERS:Onlytwo <br /> approved corrosion re- <br /> sistant nails or staples <br /> should be driven into , <br /> each shake regardless <br /> of its width. Fasteners <br /> should be positioned <br /> approximately 3/4" <br /> (19mm) (1"(25mm) <br /> per UBC)from the side <br /> edges of the shakes <br /> and 1-1/2"(38mm)(2" •• � � � <br /> (50mm) per UBC) <br /> above the butt line of <br /> the following course. <br /> Fasteners shall be long <br /> enough to penetrate <br /> itlto the sheathing Individual shakes should be spaced apart a mini- <br /> 3/4" (19mm), or mum of 3/8" (9mm) to a maximum of 5/8" <br /> thYOUgh the thiCkness (16mm)to allow for possible expansion. These <br /> of the sheathing, joints or"spaces-between-shakes"should be bro- <br /> whichever is less. ken or offset at least 1 1/2"(38mm)in adjacent <br /> courses. <br /> LITERATURE:Complete details regarding recommended applications <br /> and uses of CERTI-SPLIT shakes are given in literature available from <br /> the Cedar Shake & Shingle Bureau, 515-116th Ave. N.E., #275, <br /> Bellevue,WA 98004.
