The installation of cedar shake roofing in Vancouver involves a systematic layered approach designed to ensure weatherproofing and durability in a wet coastal climate. The process typically takes 1 to 2 weeks for standard commercial projects and follows these primary steps:
- Site Preparation and Underlayment: The existing roof structure is inspected for damage, and old materials are removed. A water-resistant underlayment, such as asphalt-saturated felt, is applied to provide a stable foundation.
- Eave Starter Course: The first row of shakes is laid along the eaves using corrosion-resistant nails. Professionals space these nails 1 to 2 inches from the edge to prevent the wood from splitting.
- Progressive Courses: Shakes are installed upward in offset patterns. Joints must be staggered by at least 1.5 inches (or 40 mm per local code) to prevent leaks, typically with 10 inches of exposure per row.
- Ridge and Hip Capping: Pre-cut ridge shakes or caps are installed at the peaks and secured with two nails each to protect against wind-driven rain.
- Flashing and Finishing: Metal flashing is integrated around vents and chimneys to ensure proper drainage. Finally, edges are trimmed, and an initial sealant or preservative treatment, such as copper naphthenate, may be applied to inhibit rot and fungal growth.
