Questions about cedar shake installation.
Why are gaps required between cedar shakes?+
Wood expands and contracts with moisture. Proper gaps support movement, drainage, and drying.
What is cedar interlayment?+
Interlayment is a layer installed between courses of shakes to provide additional water-shedding protection.
Does cedar roofing require special ventilation?+
Proper roof and attic ventilation are important because wood performance depends heavily on drying and moisture control.
