Most homeowners assume "warranty" means everything is covered. It doesn't. Understanding exactly what your warranty covers — and what voids it — before work begins is essential.
Workmanship warranty vs. manufacturer warranty
These are two separate things:
- Workmanship warranty — covers installation errors made by the contractor. Lasts typically 1–10 years depending on the contractor.
- Manufacturer warranty — covers defects in the shingles or materials themselves. Can last 25–50 years.
What workmanship warranties typically cover
Leaks caused by improper installation, flashing failures, improper nail placement, and other installation-related defects. They do NOT typically cover storm damage, normal wear, or damage caused by the homeowner.
What voids workmanship warranties
Walking on the roof inappropriately, installing solar panels or HVAC equipment without the roofer's involvement, or modifications made by another contractor can all void a workmanship warranty. Know the exclusions before you sign.
Transferability
If you sell your home, is the workmanship warranty transferable to the new owner? Get this answered in writing — it affects your home's value.
"We stand behind our work." Without written terms, that statement is worth nothing.
