EPDM Roofing

EPDM Roof Costs for Minnesota

The total cost for an average EPDM roof is between $11 and $16 per square foot. A typical assembly includes tear off and disposal off site, some insulation and the EPDM membrane. There are three ways to attach it to the flat roof: Mechanically attach it with screws and plates; Fully adhered with an adhesive; or Ballasted with river rock or pavers to the substrate. The perimeter is then secured by reusing the existing perimeter sheet metal or replaced with new sheet metal if needed. The seams are glued together with adhesive or adhered together using pressure sensitive tape and primer.

These prices would not include insulation to code. For example, if the R-value for a typical home is R-38, the requirement would be more than 6 inches of insulation. Most structures in Minnesota already have some insulation, so the price would be based, on the additional insulation required.

These prices fluctuate in terms of size and difficulty, and may cost more than noted above. Very small and difficult projects are more expensive, due to greater labor and possibly added material costs. With any of these membranes, more penetrations add to the difficulty and to the final cost. The cost is dependent on the amount of detail work required.
