A new roof is a significant investment — and like any major purchase, it should come with solid protection. That’s where your roof warranty comes in. But not all warranties are created equal.
Understanding what’s covered (and what’s not) in your roofing warranty can save you frustration, unexpected costs, and disputes down the road. In this guide, we break down the types of warranties, what they typically cover, and the common exclusions every homeowner should know.
Types of Roof Warranties
Roof warranties generally fall into two main categories — and some projects may include both:
Manufacturer’s Warranty (Material Warranty)
This warranty comes from the manufacturer of the roofing materials (shingles, tiles, underlayment, etc.).
What it typically covers:
- Defects in roofing materials (e.g., premature cracking, blistering, or granule loss)
- Specific product failures under normal weather conditions
Duration:
Ranges from 10 years to lifetime depending on the material and brand.
Important to know:
- It does not cover labor or installation errors
- Many warranties are pro-rated over time (value decreases as roof ages)
- Must follow the manufacturer’s installation guidelines for warranty to remain valid
Workmanship Warranty (Contractor Warranty)
This is provided by the roofing contractor and covers the installation of the roof.
What it typically covers:
- Mistakes made during installation
- Improper sealing, flashing, or underlayment issues
- Leaks caused by poor workmanship
