Donahue Roofing has invested both time and money to participate in ongoing education, advanced training, and proof of compliance with several manufacturers. This advanced certification process ensures that we are always using the most up-to-date materials and installation techniques, and also allows us to offer enhanced warranties in many cases. We are certified with the following manufacturers:

Donahue Roofing is a proud Mule-Hide Warranty Eligible contractor
Mule-Hide offers an extensive warranty program with several options for commercial projects, including Membrane Warranties, Standard System Warranties and Premium System Warranties.
A Mule-Hide representative inspects all commercial projects for which a Standard System Warranty or a Premium System Warranty is requested prior to the issuance of the warranty. To be eligible for a System Warranty (either Standard or Premium), the installing contractor must be a Mule-Hide Warranty Eligible contractor.
Mule-Hide also offers a selection of Membrane Warranties that are available for residential (single family dwelling projects).

Donahue Roofing is a ShingleMaster Contractor with CertainTeed
CertainTeed offers multiple educational programs for their credential contractors. Through ongoing training with CertainTeed, we have gained ShingleMaster Contractor status. Ask us how you can get a 50-year non-prorated warranty covering materials and labor. This is currently the best warranty in the industry!
