Hello. I'm installing cedar shakes ( 18" x 3/4, heavy resaws ) on a house that has a section with a 3.5 slope shed roof (22' x 14'). The application instructions recommend exposure of 7.5" for a 4:12 or steeper slope roof. What would you recommend the shake exposure to be for the 3.5" section?
Thanks for your help, Kirk
The Cedar Shake and Shingle Bureau Manual shows a detail for Shake Roof on low pitch (less than 4:12). The Detail shows a lattice built over a BUR or another Approved Roof System with shakes installed on the lattice in normal fashion. (see Attached)
