GE Enduris Roof Coating Warranties

Momentive Performance Materials (Momentive) is the exclusive licensee for GE Silicones, and manufactures and sells Enduris roof coatings.  Momentive offers two (2) types of warranties, Limited Product Warranty and Limited Material and Labor Warranty.  Material and Labor Warranties are only available for commercial buildings done by a pre-authorized contractor.  Authorized Applicators are roofing contractors who become qualified based on their experience and training.

Limited Product Warranty

Ten (10) year Limited Product Warranties are available from Momentive for commercial or residential projects that use GE Silicones Enduris roof coating.  Upon completion of the work the Authorized Applicator sends the warranty application to Momentive, which will then issue the warranty.  There are no fees or inspection.  Specific conditions and limitations are identified in the warranty document, a sample of which is available upon request.  The remedy under this warranty is to provide replacement product.

Limited Material and Labor Warranty

Ten (10), fifteen (15), and twenty (20) year Material and Labor warranties are available for work done by Authorized Applicators on commercial buildings.  These warranties help provide peace of mind to a property owner that their roof maintenance coating project will not leak water into the building due to ordinary weathering.  Remedies under this warranty include material and the labor needed to repair a leak.  Specific conditions and limitations apply as shown in the warranty document.  A sample of the warranty will be provided upon request.
There is a fee to obtain a Material and Labor warranty that includes both a fixed base and an amount per square foot, which varies with the term of the warranty.  These warranties also require pre-approval by Momentive, an inspection of the completed job, and signing of the warranty document by the owner, the contractor, and Momentive.
Both types of warranties require that Enduris roof coating be installed to the thickness specified by Momentive for the term of the warranty.  The minimum Dry Film Thickness of coating specified is 21 mils, 28 mils, and 36 mils, for ten-year, fifteen-year, and twenty-year warranties, respectively.  Thickness of coatings and sealants will be higher over seams, joints, flashings and other details.
