Sustainable Warranty Program




American WeatherStar offers both long term Material and Labor & Material warranty options on most commercial roof installations when an American WeatherStar system is installed by an Approved Contractor. Learn more about what an American WeatherStar Approved Contractor is.

Your American WeatherStar Contractor will work closely with you to choose the best system to match your roofing needs and budget. Often times the contractor will offer our material warranty along with his company’s workmanship. You should negotiate what type of warranty will be issued at the time of the contract.



Material Warranty

American WeatherStar offers a material warranty on any commercial installations installed by an American WeatherStar Approved Contractor/Contractor. The contractor must apply for warranty. Approval is based on the written application and before/ after job photos. All AWS material warranties cover our products against material defects and states that if our product is properly installed, AWS warranties it to last for the duration of the warranty. The American WeatherStar Material Warranty does not cover the building owner against leaks in the system and is limited to product replacement

Labor & Material Warranty

A labor & material warranty option that covers leaks to the AWS system installed is also available on most commercial roof projects. The American WeatherStar system must be installed by an Approved Contractor/ Contractor. A third party consultant hired by American WeatherStar will inspect and grade the installation. The installation of the American WeatherStar system must pass inspection before the warranty is issued.


To renew a warranty just contact American WeatherStar within 30 days after your warranty has expired. An AWS Contractor will survey your roof, and work with you to renew your warranty for an additional five or ten years depending on the system and environmental conditions. In most cases all it takes is trouble shooting the roof for any areas that need attention or water-proofing by following AWS application guidelines. For our Coatings or Spray Foam warranties, an additional coat or two are necessary to extend the warranty. A minimum of twelve (12) dry mils will be needed to extend the warranty ten (10) years. At completion of the project the system must be at or above the original dry film thickness. In our Single-Ply Division, we will waterproof the seams and penetrations and install the appropriate coating system to renew your existing warranty. Either way, the savings to you versus replacing your roof are significant.


All American WeatherStar warranties are transferrable to a new building owner. In order to transfer an existing warranty to new ownership please contact American WeatherStar to begin the process.

Warranty System Maintenance

Much like an automobile needs maintenance, so does your newly installed roof system. For the life of the warranty American WeatherStar recommends two inspections annually and requires a minimum of one inspection per year.
