Applying a protective sealant over an uncleaned cedar roof traps moisture and rots the wood from the inside out. π§
1. High pressure washing destroys soft wood fibers and accelerates water absorption.
2. Leaves left in the valleys hold moisture against the grain and prevent the shakes from drying naturally. πΏ
3. Stepping on wet cedar is extremely dangerous and easily cracks the brittle edges of older materials.
