Dagmar Pros | General Contractors & Roofing in Battle Ground, WA 98604

Yes, absolutely. In Battle Ground, proper integration is key. When we build a deck, sunroom, or home addition, we ensure the new structure's roofline and flashing seamlessly connect with your existing roof. This prevents water intrusion, ice dams, and debris buildup that can accelerate granule loss or create damp areas where algae thrives. Our construction approach always includes protecting the integrity of your entire roofing system.

We typically recommend addressing the roof first. Algae stains indicate persistent moisture, which can also accelerate wood rot in your deck's framing and ledger board (where it attaches to the house). By first evaluating and treating the roof—possibly with algae-resistant shingles—we create a drier environment. Then, during deck repair or replacement, we can properly inspect and seal the house attachment point, preventing future moisture damage from both directions.

Granule loss often stems from aging shingles or physical abrasion. During a deck replacement, we have a unique opportunity to inspect the lower roof edges and gutters that are usually hidden. We can clear years of accumulated granule-filled debris from gutters and roof valleys, which holds moisture against shingles. Furthermore, a new deck with proper drainage and spacing can reduce the amount of debris (like pine needles) that lands on your roof, minimizing abrasion and extending your roof's life.
