Cottonwoods and flat roofs
Leaves in fall, seed fluff in spring and twigs year-round all end up on the roof and in the canales. Debris holds moisture against the coating and blocks drainage, so water backs up during storms.
Keeping roofs healthy here
- Clean canales at least spring and fall
- Wash the roof before recoating so the coat bonds
- Trim branches back from the roof
- Check after windstorms for fallen limbs

Common questions
