Roofing warranties are more complicated than most homeowners realize, and the gap between what's promised and what's actually covered can be significant. Understanding your warranty before signing a roofing contract protects your investment and sets realistic expectations.
Two Types of Roofing Warranties
Manufacturer warranties cover the shingle product against manufacturing defects. Many are prorated after the first 10 to 15 years. Premium warranty tiers offered through certified contractors like Blue Goat Roofing cover the complete roofing system including labor, material, and related components for extended periods without proration. Workmanship warranties are separate and cover defects in the installation itself.
What Voids a Roofing Warranty
- Improper ventilation: Most manufacturer warranties require attic ventilation meeting minimum standards.
- Non-certified installer: Premium warranty tiers from Owens Corning and CertainTeed require installation by a certified contractor.
- Unauthorized modifications: Antenna installations or satellite dishes made after the roof was installed without proper flashing can void coverage in the affected area.
- Failure to maintain: Most warranties require periodic maintenance.
