Replacing a roof is one of the most significant investments a homeowner can make. With such a high cost, the warranty that comes with a new roof isn’t just a perk; it’s your protection against product defects and installation issues. Yet many homeowners unknowingly take actions that can void this warranty. Understanding what can void your roof warranty is key to ensuring your investment is secure for years.
What Does a Roof Warranty Include?
Most standard roof warranties fall into two parts:
- Manufacturer’s Warranty: Covers roofing materials and manufacturing defects.
- Workmanship Warranty: Offered by the contractor to cover errors during installation.
Across the different types of roofing warranties, durations often range from 20 to 50 years, but their validity is always contingent on adhering to the specified terms.
1. Adding New Installations Without Approval
Installing solar panels, satellite dishes, or skylights might improve your home, but they can interfere with your roofing system. If you allow work that cuts into the roof without using approved methods or technicians, your warranty could be canceled. Always check with your roofer or manufacturer before any rooftop additions.
2. Poor Attic Ventilation
Ventilation helps regulate temperature and moisture. When airflow is limited, heat and condensation build up under the roof deck, leading to damage over time. Shingle warping, mold, and shortened lifespan can result. Most warranties won’t cover this kind of damage since it’s considered a preventable issue.
3. Cleaning with High-Pressure Washers
While it may seem like a quick fix for a dirty roof, pressure washing can strip away protective granules and loosen shingles. This can lead to leaks and premature wear, which are often excluded from warranty coverage, complicating the warranty process in Minnesota if you need to file a claim for the resulting damage. Use low-pressure or soft-wash methods instead.
4. Using Non-Approved Materials for Repairs
If repairs are needed, using materials not approved by the manufacturer can void your roof warranty. Compatibility matters. Unapproved sealants, flashing, or shingles may affect performance and are grounds for denying a claim. Always ask for approved materials during repairs
5. Hiring Unqualified Contractors
Manufacturers require certified installers to guarantee quality. This means that if an uncertified contractor does repairs, your roof warranty could be invalid, even if the work appears to be good. This is a crucial reason to hire a certified roofing contractor. Choosing a cheaper, uncertified option can lead to significant problems and may void your warranty.
6. Skipping Routine Maintenance
Roof warranties don’t mean “no maintenance required.” Most manufacturers expect routine care. That includes clearing debris, checking for loose shingles, and cleaning gutters. Neglecting these basic tasks could void your warranty due to what’s considered homeowner negligence.
7. Waiting Too Long to Fix Storm Damage
After a storm, even minor damage should be addressed quickly. Most warranties have a window for reporting and fixing issues. If you miss that deadline, your claim may be denied—even if the damage would have been covered. Keep photos and act fast after severe weather.
Protect Your Warranty—and Your Roof
To avoid losing your coverage:
- Keep records of roof work and inspections.
- Use certified contractors and approved materials.
- Perform regular maintenance and inspections.
- Review your specific warranty terms carefully.
These steps will help make sure your protection stays intact.
