For Portland roofs, timing your cleaning around leaf season depends on your situation. If you’ve got visible moss, algae streaking, or blocked drainage, don’t wait—act before fall moisture accelerates the damage.

Your driveway gets slippery overnight in the fall because cooling temperatures drop below the dew point, causing moisture to condense directly onto the pavement surface.

As days get shorter, dirty windows compound the problem by blocking up to 40% of your natural light.

Once fall rains arrive, your paver joints wash out faster because the rain hits in concentrated bursts, creating hydraulic pressure that forces loose sand out of joints almost immediately.

During Oregon’s darker months, your solar panels are already working with reduced sunlight—dirty panels make that deficit far worse.

Once fall humidity rises above 70%, your fence boards pull moisture directly from the air, not just from rain. Dropping temperatures slow evaporation, so wood never fully dries between wet cycles.

When wet leaves sit on your concrete, they release tannins that penetrate the porous surface within hours.

After the first heavy fall storm, you’ll want to inspect your roof from the ground using binoculars, checking for missing, curled, or cracked shingles, lifted flashing, and sagging sections.

Fallen leaves and moisture accelerate algae and biofilm growth, creating an invisible layer that strips traction from concrete, pavers, and wood.

Portland’s wet fall climate turns your gutters into a trap. Rain saturates fallen leaves, compressing them into dense, waterlogged mats that block drainage fast.
