Duro-Last® Installation
H. Treder & Sons, Inc. has been installing the Duro-Last roofing system on flat and low slope roofs, including new roofs, old roofs, damaged roofs, and even over failed metal roofs since 1985. The Duro-Last roofing system provides the highest quality and consistent watertight integrity that any building owner looks for. Our dedicated, cohesive roofing team offers top quality workmanship and great efficiency while installing a superior product.
Our commitment to quality and excellence is demonstrated by the actual installation of our roofs. As a contractor, we have received the highest inspection grade possible on every completed jobsite. This grade can only be given by an outside Duro-Last quality assurance inspector before any warranty on the roof is issued. Unlike other contractors who install Duro-Last, we use a two-man welding procedure. This process ensures you, the customer, the utmost perfect weld that can be achieved -- as evidenced by our high inspector grades. H. Treder & Sons, Inc. is the only Duro-Last company which has never had to return and repair a job we installed. We place extreme value in the satisfaction of our customers, and a high quality, professional installation at the most competitive pricing available is guaranteed.
