Getting a new roof is a big investment for an important component of your commercial building. Even if you get the “best roof” and the “best roofing contractor,” there still may be some problems that arise. After all, there is no 100 percent guarantee that everything will go right with your roof for the next 15 years or more. Therefore, it is important to have a solid warranty for your new roofing system.
The length and extent of warranty coverage may depend on the type and thickness of material used. Typically, thicker membranes will have more options available with respect to warranty length and what’s covered. Basic warranties are usually provided at no extra cost, but some may require an upcharge, meaning the building owner contributes to the cost of the warranty at the time of purchase. Some warranties may require regular inspections by an authorized contractor to remain in effect.
There are “material” warranties and “labor” warranties, that cover what their names suggest. “Full system” warranties combine the two. Some warranties provide prorated coverage, based on the number of years the roof has been in place since installation. Some will cover the original cost of the roof. No-Dollar-Limit (NDL) warranties have no cost limitations for covered warranty claims. Most NDL warranties cover both labor and material defects. Some also cover contractor workmanship.
Before purchasing a new roofing system, part of your evaluation should include the warranties that are available, and which is best for your situation. A reputable commercial roofing contractor can help guide you, as the choices, obviously, can be daunting.
Ultimately, the quality of a roofing installation comes down to the craftsmanship of the installer on the roof, and some contractors will back their work with their own workmanship warranty. For your long-term peace of mind, choose the combination of a roofing system that has a solid manufacturer warranty and that’s installed by a contractor that provides a workmanship warranty.
