Roofs By Design | Roofing Services in Vancouver, WA 98684

Proper ventilation is key in our damp climate. During a new installation, we design and install a comprehensive ventilation system tailored to your attic space. This system, combined with high-performance underlayment and insulation, allows moisture to escape, preventing condensation that can lead to mold, wood rot, and reduced insulation effectiveness, protecting your home's structure and energy efficiency.

Flashing is the metal barrier that seals roof joints and valleys, areas highly vulnerable to leaks. Due to frequent rain, Vancouver roofs are prone to flashing corrosion. During a full roof replacement, we remove all old, corroded flashing and install new, heavy-gauge aluminum or galvanized steel flashing. This creates a watertight seal at the most critical points, preventing the leaks that often start at these weak spots.

For durability against Vancouver's weather, we recommend architectural asphalt shingles for their layered protection and longer warranties, paired with a synthetic underlayment that provides a superior moisture barrier. For flashing and metalwork, we use corrosion-resistant metals like aluminum or coated steel. These material choices, installed with expert craftsmanship, are your best defense against the specific moisture and corrosion challenges our local roofs face.
