Flat roofs fail at the details.

A low-slope roof has nowhere to shed water quickly, so every seam, drain, and parapet termination has to be right. They rarely fail in the field of the membrane. They fail at a drain that was never flashed properly or a parapet cap that was never sealed.

We run TPO and modified bitumen on residential low-slope, and we build rooftop decks and vegetative assemblies over them. The Oak Lawn rooftop deck and the Kessler Park TPO and vegetative roof are both ours.

What the job includes

• TPO single-ply and modified bitumen systems
• Rooftop deck and terrace assemblies
• Vegetative and green roof build-ups
• Drain, scupper, and parapet detailing
• Ponding correction with tapered insulation
• Coating and restoration where the deck is sound

What it costs

We do not publish a price range, because a range that fits every house is a range wide enough to be useless. What drives your number: square footage, pitch, how many layers come off, how much decking is soft, the material you pick, and how complicated the flashing details are. We walk the roof, put all of it in writing, and the number does not move unless we find something and tell you first.
