of solar systems over its roofing does not void its manufacturer warranty. Nevertheless, the cost of removing installed solar systems to inspect the shingles is not warranty-covered.
1. Owens Corning
Owens Corning offers a straightforward warranty, which covers the manufacturing defects in their products and not other manufacturers’ products. The shingles warranty will remain when a solar system is installed. However, the standard warranty doesn’t cover the cost of removing the solar system in order to replace a faulty roofing product.
This company not only offers a manufacturing warranty but also a service warranty. The warranty provides 15 to 25 years for workmanship or manufacturing defects that results from installers from Master Installers or Credentialed. This is because the warranty coverage is integrated with its credentialed installer program.
3. Malarkey Roofing Products
In their technical bulletin, Malarkey allows solar installations on their roofing products and does not affect the warranty. The only issue is that the warranty does not cover damages as a result of solar system installation.
