Whether you’re having a new roof or siding installed, it’s important to hire a contractor who offers comprehensive warranties. A roofing warranty protects your new roof in case something bad happens to it. However, the things that you do and don’t do for your roof can void your warranty.

Here are some of the common causes of a voided roofing warranty.

Layering New Shingles Over Old Ones

Some contractors may claim that it’s more cost-effective and less labor-intensive to install new shingles over the old roof. But doing so can actually cost you more over time because this type of installation can void your roofing warranty. Without removing the old material, your contractor won’t be able to check if the material underneath the shingle is deteriorating. Also, the added weight of the new shingles can compromise the structural integrity of your roof. 

Poor Maintenance 

Your manufacturer’s warranty may state routine maintenance as part of the terms. This may include tasks such as keeping the roof debris-free and making sure that the drainage system is unclogged to ensure proper water flow. Regular maintenance can help prolong the life and avoid significant roof repair costs. 

Improper Installation

Roof installation is best done by professionals for a reason. This job requires the right equipment and proper training. Failure to comply with the manufacturer’s specifications for installation can void your warranty. Taking shortcuts can risk both the integrity of your roofing system and its protection. Working with a manufacturer-certified roofing contractor can help you avoid installation issues.
