Does a manufacturer warranty cover every roof leak?+
No. Manufacturer warranties generally focus on qualifying product defects. Leaks caused by installation, flashing, storms, maintenance, structure, or unrelated components may not be covered.
What is a prorated roof warranty?+
Prorated coverage reduces the available benefit as the roof ages according to the warranty schedule.
Does a material warranty include installation labor?+
Not always. Standard warranties may cover only qualifying materials, while some enhanced warranties include limited labor coverage.
Who decides whether shingles are defective?+
The manufacturer generally reviews the claim, documentation, samples, installation conditions, and inspection findings under its written warranty process.
