Max Protection

Most asphalt shingle manufacturer warranties include maintenance conditions — and heavy, prolonged moss coverage can be used to deny granule-loss and shingle-failure claims. Understanding what BC manufacturers actually require helps homeowners protect their warranty coverage through regular professional treatment.

What BC Shingle Manufacturers Require

Major asphalt shingle manufacturers selling in BC — IKO, GAF, BP (Buildex), and Certainteed — all include maintenance language in their limited warranties. Common requirements: the roof must be kept "free of debris and biological growth that would prevent proper drainage"; granule loss caused by "improper maintenance" is typically excluded from coverage; algae warranty riders (included in many premium shingle lines) specify that "chemical treatment and cleaning as recommended by the manufacturer" must be performed. A professional biocide treatment record from Roof Labs Canada serves as documentation that you've met these maintenance requirements.

How Moss Coverage Affects Warranty Claims

If you file a warranty claim for granule loss, premature aging, or shingle failure, the manufacturer's inspector will assess the roof condition. Heavy moss coverage at the time of inspection — or evidence of extended untreated moss in photos — provides grounds to deny the claim as maintenance-related failure. The claim denial language typically reads: "damage attributable to lack of maintenance, including biological growth." Regular treatment (every 2–3 years) with professional documentation removes this risk entirely. A treated, moss-free roof at inspection time demonstrates proper maintenance regardless of the reason for the claim.

Protecting Your Warranty with Treatment Records

Roof Labs Canada provides a written treatment report for every job — date of treatment, products applied, areas covered, and guarantee terms. Keep this document with your home records alongside your roofing warranty. It creates a maintenance trail that demonstrates proactive upkeep. If you are preparing to file a warranty claim and your roof currently has heavy moss, professional treatment before the inspector visits is advisable — a clean roof at inspection removes the most common basis for denial.

Frequently Asked Questions

Can I claim warranty on a roof that has had moss?

Yes, if the roof was treated and is currently well-maintained. Manufacturers inspect current conditions and documented maintenance history. A treated roof with a professional record is in a much stronger position than one with active heavy coverage at time of inspection.

Do algae warranty riders cover Gloeocapsa magma on BC roofs?

Some premium shingle lines (IKO Dynasty, GAF Timberline CS) include algae-resistance warranties that cover staining from Gloeocapsa magma. However, these warranties typically require that cleaning be performed "per manufacturer recommendations" — which specifies professional soft-washing, not pressure washing or scraping.
