The new roof installation process in Vancouver and the Lower Mainland is a comprehensive procedure designed by Paragon Roofing BC to meet British Columbia Building Code standards and the demands of a wet coastal climate. The process follows these professional steps:
- Inspection and Preparation: The project begins with a thorough inspection of the existing structure for damage and leaks. This is followed by the removal of old roofing materials and an inspection of the decking to ensure structural integrity.
- Waterproofing and Underlayment: Builders install critical protection layers, including ice and water shield underlayment and metal flashing. These components are essential for preventing leaks in Vancouver’s heavy rainfall.
- Component Installation: Starter strips and specialized roofing materials are applied. For asphalt shingle installation, workers apply shingles row by row using proper nailing techniques. High-quality self-sealing shingles are often used to resist winds up to 110 mph.
- Compliance and Safety: Throughout the process, contractors must adhere to BC Building Code Section 9.26 regarding wind load resistance, fire ratings, and drainage. Safety protocols include using WorkSafeBC-mandated fall protection like harnesses and guardrails.
Professional installation typically takes into account local challenges such as urban density and strata rules, often yielding a roof that lasts between 18 and 50 years depending on the materials and warranty selected.
