Avoid these common roofing installation mistakes
When investing in a new roof, understanding its warranty is just as important as selecting the right material. A roof warranty safeguards your investment by covering potential defects, workmanship issues, or material failures—but not all warranties are created equal. Knowing what’s included and what’s excluded can save you from unexpected expenses and confusion later on. This comprehensive guide explains how roof warranties work, what they cover, and what limitations you should watch out for.
A roof warranty is a written guarantee provided by either the manufacturer or the roofing contractor that promises repair or replacement if certain issues arise within a specific period. It ensures homeowners that the materials and workmanship meet industry standards. However, the type of coverage and length of protection can vary widely depending on the roofing material and the company offering it.
There are typically three main types of roof warranties:
A manufacturer’s warranty protects against defects in the roofing products themselves—such as premature cracking, blistering, or granule loss in asphalt shingles. Coverage duration varies by material, with asphalt shingles usually warrantied for 20–50 years and metal or slate roofs often covered for up to a lifetime.
The workmanship warranty focuses on the installation process. If leaks or damage occur due to improper installation, the contractor is responsible for repairs or replacement. These warranties generally last between 2 and 10 years, depending on the contractor’s policy and certification level.
A system warranty, often offered by roofing manufacturers, provides the most extensive protection. It covers both materials and labor as long as the installation meets the manufacturer’s requirements. This type of warranty may also include components such as underlayment, flashing, and ventilation systems, ensuring full-roof coverage against failure.
While warranties provide peace of mind, they don’t cover everything. Common exclusions include:
Some warranties can be transferred to a new homeowner, which adds resale value to your property. However, many warranties have limitations—such as allowing only one transfer or requiring a fee and registration within a set period after the sale. Always check the fine print if you plan to sell your home.
Most manufacturers require homeowners to register their roof warranty within a specific timeframe after installation. Failing to register can result in reduced coverage or complete loss of warranty protection. Keep all documentation, including receipts, contracts, and installation records, as proof of compliance.
Routine maintenance is essential to keep your warranty active. Schedule annual inspections, remove debris, and ensure proper ventilation. Document all maintenance and repairs with photos and receipts to prove you’ve upheld your end of the agreement should you need to file a claim.
If you encounter a problem with your roof, contact your contractor or manufacturer immediately. Provide all relevant documentation, such as warranty certificates, photos of the issue, and proof of maintenance. Most companies will send an inspector to assess the damage and determine whether it qualifies under warranty terms.
Conclusion
A roof warranty is more than a piece of paper—it’s a valuable form of protection that can save you thousands in repair costs. However, understanding its terms, limitations, and maintenance requirements is key to maximizing its benefits. Always read the fine print, keep thorough records, and maintain your roof regularly. By doing so, you’ll ensure that your warranty remains valid and your home stays protected for years to come.
