In British Columbia, 50-year shingle warranties are common but require careful verification of the fine print. While manufacturers do offer these long-term coverages, they are rarely "lifetime" guarantees in the literal sense.

Key details to verify include:

• Proration: Most 50-year warranties are prorated, meaning the coverage value diminishes over time. They typically provide full replacement costs only in the initial years and then transition to a diminishing credit for defective materials.
• Transferability: A 50-year warranty is not automatically transferred to a new owner. Verification involves notifying the manufacturer, completing specific forms, and paying a fee (usually $100–$200) within a strict timeframe after a property sale.
• Strict Requirements: These warranties can be voided by factors such as improper attic ventilation, unauthorized repairs, or lack of professional maintenance.

To ensure your warranty is verifiable and valid, you should request written documentation for all terms from your contractor and confirm the product registration was completed with the manufacturer.
