Duro-Last® Roofing

Allstate Roofing highly recommends the Duro-Last® roofing system. As a Roofing contractor Oklahoma area we understand the problem with flat roofs in the winter. The surface of the Duro Last® system is so slick that snow and ice can be removed with a broom. We have found this product to perform exceptionally well on older homes where the issue of some puddling occurs, Duro-Last® has no problems with standing water as the material performs almost like a swimming pool liner, but many times tougher.

The Duro-Last® system can be installed over current roof. Our Qualified roofers will inspect the existing roof for presence of moisture. If none is found, we then install an underpayment of 1/2 foam board to protect the Duro-Last® membrane from exposure to the old roofing material to protect your warranty and enhance the insulation on the roof.
