Great Portland Construction | Roofing Services in Newberg, OR 97132

Roof valleys channel a lot of water, especially during our heavy Oregon rains. Over time, wear, debris buildup, or improper installation can cause leaks. We fix them by first clearing all debris, inspecting the underlying flashing and shingles, and then applying a durable, waterproof sealant or replacing damaged sections with precision to restore a seamless water channel.

Moss traps moisture against your roof, leading to rot and granule loss. We recommend a professional, low-pressure cleaning to safely remove the moss without damaging shingles. Critically, we then apply a zinc or copper-based treatment at the roof's ridge. As rain washes over it, this creates a protective zone that inhibits future moss growth for years.

Absolutely. As a full-service contractor, we manage the entire project. We'll start by permanently fixing the exterior roof leak. Then, our team can seamlessly repair any resulting interior damage—like stained ceilings, damaged drywall, or insulation—coordinating all the trades needed to restore your home completely, inside and out.
