What cottonwoods drop
- Spring: seed fluff that drifts into corners and canales
- Summer: twigs and small branches, especially in storms
- Fall: heavy leaf drop that mats on roofs
Why it matters
Debris holds water against the coating, blocks canales and makes water back up behind parapets. A blocked canale during a summer downpour is one of the most common causes of flat roof leaks in Corrales.

A simple plan
- Late spring — clear fluff from corners and canales
- Early summer — check canales before storm season
- Late fall — clear leaves
- After big windstorms — look for fallen limbs
Trimming
Keeping limbs back from the roof reduces debris and branch damage. Large cottonwoods are best handled by a tree service.

Common questions
Does fluff hurt the coating?
Not directly, but it traps moisture and blocks drainage.
Can I clean canales from a ladder?
If you can do it safely. Otherwise, have it done.
