Manufacturer
Material coverage
Covers defects in the shingles and accessories themselves. Standard limited warranties are prorated — coverage shrinks year by year, so a claim in year 20 is worth a fraction of the replacement cost.
Coverage
What your warranty actually covers
Most homeowners are handed a certificate they never read. Here is the plain-English version of how roof warranties work and where they fail.
Two halves
Material vs workmanship
Installer
Workmanship coverage
Covers installation errors, which is where the overwhelming majority of roof failures actually originate. A contractor-only workmanship warranty is worth exactly as long as the contractor stays in business.
The upgrade
50-year non-prorated system
When a complete manufacturer system is installed to manufacturer spec — starter strip, leak barrier, synthetic underlayment, shingles, ridge cap and balanced ventilation all from one manufacturer — the roof qualifies for an enhanced system warranty.
The meaningful differences: coverage is non-prorated for the first decades rather than declining from day one, workmanship is backed by the manufacturer rather than only the installer, and tear-off and disposal are included in a covered claim.
Coverage is transferable, which matters at resale — a documented, registered system warranty is a line item buyers and home inspectors both take seriously.
Fine print
What voids coverage
Inadequate ventilation
Nearly every manufacturer requires balanced intake and exhaust. Unbalanced attics are the most common denial reason we see.
Mixed accessories
Using another brand's starter, underlayment or ridge cap drops the roof out of system coverage.
Unregistered installs
Enhanced warranties must be registered after completion. We register yours and send you the certificate.
