GC III Contracting | General Contractors & Roofing in Portland, OR 97225

In Portland, the most common causes are worn-out flashing around chimneys or vents, and damage from moss or debris trapping moisture. We start with a thorough inspection to locate the exact source of the leak. Our repair process involves replacing damaged shingles or flashing, sealing any vulnerable areas, and often includes a preventative roof cleaning to remove moss and ensure long-term protection against our wet climate.

Absolutely. As a full-service contractor, we're uniquely equipped to manage the entire project. First, our roofing team will permanently repair the leak from the outside. Then, our drywall specialists will remove any water-damaged material, treat the area to prevent mold, and expertly patch, finish, and texture your walls or ceiling to match the existing surface, leaving no trace of the water damage inside your Portland home.

Preventative care is key here. We offer professional roof and gutter cleaning to remove moss, leaves, and debris that hold moisture and accelerate wear. We also install and maintain gutters to ensure proper water drainage away from your roof and foundation. For older roofs, we can provide a detailed assessment and recommend targeted repairs or a full replacement with materials suited for longevity in the Pacific Northwest.
