We replace and repair flat roofs every week. From inception, because of their neutral slope, flat roofs are designed to leak. Our proposition for most flat roofs is to completely remove the old roof system down to the original substrate. We then repair any rotted decking and/or wet insulation . We add a layer of tapered insulation to give the roof positive drainage. Then, we install a TPO membrane, complete with welded seams and flashings.
Thermoplastic polyolefin (TPO) is a single-ply roofing system that is one of the fastest growing commercial roofing products in North America. TPO's popularity is in part due to its heat-reflective quality and ability to absorb expansion and contraction impacts on a roof system.
