Business ProfileforJ&M Roofing Services Inc.

We signed an agreement with J&M to have our roof replaced. This included new shingles and underlayment. We received a quote and paid a deposit of $3000 before the work began on September 11.After the roofing project was completed, it came to my attention that the underlayment, specifically the RhinoRoof U20, was not installed in accordance with the manufacturers installation instructions. I received installation instructions from J&M, and these clearly stated that the underlayment should be anchored with staples, cap staples, or roofing nails when covered with primary roofing on the same day. Contrary to these instructions, your company primarily used staples to secure the underlayment and left it exposed to the elements without protection for an extended period(4-5days), which, as I have learned, voids the manufacturers warranty.I have repeatedly raised these concerns with J&M, and while some attempts were made to address the workmanship and property damage issues, my primary concern regarding the underlayment and the voided manufacturers warranty has not been adequately resolved. I have spoken to the manufacturer and they stated the use of staples to secure the underlayment is not recommended.I would like a refund of my $3000 and in return I will return the faulty installed materials to the company. I provided J&M with a photograph which supports our concerns with the underlayment but they would not take accountability of the faulty installation.
