Flat and low-slope roofs in Kalamazoo
For flat and low-slope buildings in Kalamazoo we install TPO and PVC membranes. TPO runs $8.50 to $13.50 per square foot and PVC $9.50 to $14.50, before the things that move a commercial price, such as a concrete deck, tapered insulation or extra layers to tear off. We put down 60-mil membrane as standard. Our flat roofing page sets the systems side by side.
One Michigan difference shows up in every bid here. Michigan requires R-30 insulation under a new commercial roof, roughly 5 inches, where Indiana requires R-20. The upgrade adds about $100 to $115 per square (100 square feet), so a Kalamazoo bid should come in above an Indiana one for the same building. Where the deck and insulation under an aging membrane are still sound, we also apply Conklin roof coatings. The core sample we take at the inspection tells us whether yours qualifies.
Inside the City of Kalamazoo, the re-roof permit covers commercial buildings as well as homes, at $52 per structure, on the city's roofing and siding permit application. For a house in the area, see roofing in Kalamazoo.
