Seasonal Maintenance December 16, 2025

December brings colder temperatures, steady rain and occasional wind that can stress even a well-built roof. A simple maintenance routine helps protect your home during the wettest part of the year and prevents small issues from becoming costly repairs. Homeowners across Portland, Beaverton and Hillsboro can use this checklist to prepare their roofs for winter weather.

At PDX Roofing and Siding, we help Portland-area homeowners stay ahead of winter roofing issues with thorough inspections and reliable recommendations. Our team understands how constant rain, moss growth, and wind impact roofs in the Pacific Northwest, and we tailor every service to the needs of local homes.

Clear Debris and Check Gutters
Leaves and branches collect quickly in December. When gutters clog, water backs up under shingles and causes moisture damage. Inspect your gutters and downspouts, remove debris and confirm that water flows away from your home. This is especially important for homes near tall trees in neighborhoods like Murrayhill and Bethany.

Inspect Shingles and Flashing
Look for lifted shingles, cracked sealant or exposed nail heads. Rainwater can slip through small openings and reach the attic. Flashing around chimneys, vents and skylights should sit tight and show no signs of rust or gaps. These areas are common leak points during Portland’s winter storms.

Remove Moss and Check for Moisture
December moisture encourages moss growth. Moss traps water and accelerates shingle wear. If you notice green patches, schedule a safe removal. Inside your attic, look for damp insulation or musty odors. These often indicate early-stage leaks.

Schedule a Professional Roof Inspection
A winter inspection from PDX Roofing and Siding provides a clear picture of your roof’s condition. We identify hidden issues, document our findings with photos and offer practical recommendations tailored to Pacific Northwest weather.
