Commercial low-slope.
Small commercial buildings, multi-family, shops, churches and outbuildings. We’re not a 200,000-square-foot outfit and we don’t pretend to be — but on a building up to mid-size, you get the same crew, the same photographs and the same warranty as everyone else on this site.
The systems.
TPO — a white, single-ply membrane with heat-welded seams. Reflective, so the building runs cooler in July; the seams are fused, not glued, so they’re as strong as the sheet. Our standard on most low-slope work.
EPDM — the black rubber roof. Forgiving in Colorado’s freeze-thaw, easy to repair, and the right choice on some older buildings and additions.
What’s under them matters more than which one you pick: tapered insulation so the water goes to the drains instead of sitting in the middle of the roof, cover board over it, and every curb, unit and pipe flashed into the membrane properly. A flat roof that ponds is a flat roof that’s failing, and most of the ones we replace failed there first.
Drains, scuppers and the things on the roof.
Low-slope roofs leak at the edges and the penetrations — the drains, the scuppers, the rooftop units, the conduit somebody ran across the roof in 2014. We rebuild the drain sumps, replace the scupper boxes, and flash the curbs. If your HVAC contractor needs to get on the roof afterwards, we’ll put walk pads where they’ll walk.
Working around an open business.
We schedule the loud parts around your hours where we can, keep the dumpster off the customer parking, and don’t leave a half-finished roof over a Friday. The building stays dry every night we’re on it.
Afterwards.
A flat roof wants looking at twice a year — drains cleared, seams checked, photographs on file — and it’ll last twenty-plus years if it gets it. We offer that as a standing arrangement, with the photos in your inbox each visit. It costs less than the first leak.
Go up after the next rain and look for standing water forty-eight hours later. Where it’s still sitting is where the roof is failing, and the photo of it is the most useful thing you can send us.
Got a flat roof that ponds?
Send us the photo. We’ll come look at the drainage before we talk about the membrane.
