NW Subpros | Gutter Services & Roofing in Portland, OR 97202

In our wet climate, clogged gutters are a primary cause of water damage. Our thorough cleanout service ensures rainwater is properly channeled away from your roof, siding, and foundation. This prevents costly issues like basement flooding, wood rot, and soil erosion around your property, which are common concerns for local homeowners.

Absolutely. We use a specialized, low-pressure treatment designed to safely eliminate moss, algae, and organic stains without damaging your roofing materials. This gentle approach cleans your roof effectively while preserving the integrity of the shingles, which is crucial for extending their lifespan in our damp environment.

We frequently address roof valley leaks and nail pops, both exacerbated by our seasonal temperature swings and moisture. For valley leaks, we conduct a detailed inspection to locate the failure point in the flashing or underlayment and perform a precise, watertight repair. For nail pops, we securely re-seat or replace the fasteners and seal them to prevent future water intrusion and thermal movement issues.
