Q: How will I know if I need a tear-off or a re-roof?
A: Our estimator will perform an on-site inspection of your roof. At that time, he will core the roof to inspect the layers that are on your building. That inspection will reveal the saturation level of the roofing materials under your top layer of roof and help decide if you need a tear-off or re-roof.
Q: Why do I need at least 5.2" of polyiso insulation for a tear-off?
A: Michigan follows ASHRAE standards. The minimum R-value for non-residential buildings in our climate zone is R30 (climate zone 5 with insulation entirely above the roof deck). Currently, two layers of 2.6" polyiso insulation achieve a total R-value of R30.
Q: Do I need to achieve an R30 for a re-roof?
A: No. The code applies to tear-offs. It would be the customer's discretion to add R-value to the building in a re-roof application.
Q: Is M.W. Morss Roofing, Inc. a union company?
A: Yes. Our roofers are members of Local 149 and our sheet metal workers are members of Local 80.
