10 Warning Signs of Roof Damage Most Portland Homeowners Miss
Take a slow walk around your house this weekend with your phone or binoculars. Many Portland families overlook these subtle but important warning signs until water finds its way inside. Here are 10 common red flags we spot regularly on roofs across the Portland metro area:
Heavy Granule Loss
Granules collecting heavily in gutters or along the driveway after rain.
Curling or Buckling Shingles
Shingles that are curling, buckling, or lifting at the edges, especially on south and west exposures.
Moss and Algae Growth
Thick patches of green or black moss, particularly on the shaded north side and under trees.
Sagging Roofline
Sagging or uneven areas along the roofline or eaves.
Interior Water Stains
Dark water stains or discoloration on ceilings and walls inside the house.
Musty Attic Odors
Musty odors or signs of dampness when you enter the attic.
Damaged or Missing Flashing
Loose, cracked, or missing flashing around chimneys, vents, skylights, and valleys.
Debris Buildup in Valleys
Excessive debris or pine needles trapped in roof valleys.
Worn Ridge and Hip Shingles
Visible wear on ridge caps or hip shingles from years of wind exposure.
Excessive Indoor Humidity
Increased humidity or condensation on windows during rainy periods.
