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:

1. 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.
2. 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.
3. 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.
4. 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.
