4 Things That Can Void Your Roof Warranty

4 Things That Can Void Your Roof Warranty




Investing in a new roofing system is a big and expensive step. That’s why you need to make sure you have all your bases covered. You should, for example, understand the warranty included with your replacement roof. Check the fine print for actions that can inadvertently void its coverage. 3JM Exteriors, premier roof and window replacement expert in the area, details some of them here.

  1. Installing new shingles over the old ones. You’ll need a thorough understanding about your roof warranty coverage to avoid any pitfalls. One of the most common mistakes some homeowners make is getting a re-roof. This project involves installing a new roofing system over the old one. While this method can be more cost-effective than a completely tear-off, you’ll soon find that it’s more trouble than it’s worth. Reroofing not only voids your warranty, it can also shorten the service life of the new system. What’s more, it can damage the existing roof structure because of the additional weight and improper ventilation.

  1. Poor ventilation. When choosing a new roof for your home, make sure that a good ventilation system is in place. Otherwise, heat and moisture will build up in the attic and encourage mold growth. Additionally, the trapped heat can rise and cause premature aging in the new shingles above. Improper ventilation won’t be covered by the roof warranty, so it pays to have it promptly dealt with. 3JM Exteriors can help you with this. We’re not just your siding repair expert. As one of the trusted contractors in the area, we make sure every roof we install includes high-quality ventilation for improved performance and longer service life.

  1. Mounting a satellite dish or antenna on the roof. Installing these items will involve drilling holes in your roof, which makes it more vulnerable to water infiltration. When overlooked, these leaks can lead to extensive water damage in your roof and home. You should reconsider these installations to avoid nullifying the warranty, and to keep your roof leak-free.

  1. Subpar roof installation. Most roofing systems, no matter the brand, come with a warranty against poor workmanship. You’ll want to ensure your roofing system is installed according to manufacturer specifications to avoid nullifying it. For this reason, it pays to work only with an experienced and certified general contractor like 3JM Exteriors. We are an Owens Corning® Platinum Preferred Contractor, which means we can safely and efficiently install your new roofing to the brand’s high-quality standards.
