When you invest in a new roof, you expect protection against the elements and unexpected repairs. That’s where a roof warranty comes in. But not all warranties are created equal, and the fine print is easy to overlook. Explore what your roofing warranty may cover to help you avoid costly surprises and enjoy peace of mind for years to come.
Manufacturer vs. Contractor Coverage
A roofing warranty generally covers two main areas: materials and workmanship. The manufacturer’s warranty protects you against defects in the roofing materials themselves, such as shingles that crack, blister, or lose granules too quickly. On the other hand, the contractor’s workmanship warranty covers errors related to how the roof was installed.
In most cases, the manufacturer’s coverage lasts 10 to 15 years, during which time both materials and labor are covered. After that, it usually shifts to prorated coverage, which means the manufacturer pays only a portion of the replacement costs based on the roof’s age.
Some warranties also include system coverage, which applies if you install an entire suite of the manufacturer’s roofing components, including underlayment, ventilation, and shingles, rather than mixing and matching brands. This unlocks a longer protection period and more comprehensive coverage.
What’s Not Covered
Although roofing warranties offer strong protection, they don’t cover everything, including neglect, improper maintenance, or DIY repairs. That’s why it’s important to keep your roof in good condition and follow the manufacturer’s care guidelines. Specific warranty exclusions often include the following:
- Storm, hail, and wind damage
- Leaks caused by falling tree limbs or animals
- Issues with components not installed by your roofing contractor
- Damage from pressure washing or foot traffic
How Long Is a Roof Warranty?
The average roof warranty for material coverage is 25 to 50 years, depending on the brand and product tier. Many roof systems advertise “lifetime” warranties, but it’s worth checking the details. These often mean coverage for as long as you own the home, with the value decreasing over time.
Workmanship warranties are typically shorter. Some contractors offer one year, while others provide protection for five to 10 years. Higher-tier warranties offered through certified contractor programs may extend that coverage further.
It’s also worth asking whether your warranty is transferable. Some allow the next homeowner to receive coverage, which boosts your home’s resale value.
How to Protect Your Roof Warranty
Follow these best practices to make the most of your coverage:
- Hire a licensed contractor certified by the shingle manufacturer
- Register your warranty shortly after installation, if required
- Schedule regular inspections to catch minor problems early
- Avoid modifying or repairing the roof without professional help
- Keep records of all maintenance and service visits
