The best warranty in the construction industry is a single-ply membrane roof warranty (TPO or thermopolyolefin , E.P.D.M., P.V.C., Modified Bitumen).
Firestone Building Products is leading in this area with their “edge to edge” roof warranty which covers all the roofing accessory products installed (membrane, roof insulation such as poly – iso board, fasteners, flashings, metal drip edge or coping or gravel stop, etc. These are on commercial flat or low slope roofs with positive drainage.
Of course one can get just a material or a membrane only warranty, ( residential or commercial) accompanied by the roofing contractor’s labor warranty, but I am speaking of a workmanship (labor) and material warranty by a multi-billion dollar company. Firestone even inspects the roof to be sure it is installed as per their specifications. A contractor must be certified by them to obtain one of these warranties which means you are sure you have picked a good roofer. Any roofer can get a material warranty. Only the best are Firestone certified.
These warranties are non pro-rated, have a no dollar limit, and are available in duration of 5, 10, 15. 20, 25 and 30 year increments. Yes, they can guaranty a roof against leaks and other defects for 30 years! They do this because they know their roof system will perform and last.
You know what non pro-rated means. No dollar limit means that 29 years from now, on a 30 year roof, inflation doesn’t matter. If a repair costs 20 times more than it does now, they still have to provide material and labor to do it. And most of the time these warranty repairs are made in just a few days because we make them for Firestone and Genflex Roofing Systems and they pay us to do so.
I would say that these roof system warranties may even be the best in any industry and not just in roofing or construction. Can you get one like it on a car or a microwave oven? Nope. I don’t think so.
