  • These guys did a great job on our roof. I’ve worked with numerous roofers and these guys are by far my favorite. Patrick and his crew did great work and communication clearly.

  • Patrick of WestPro Roofing looked at my roof the day after I called and was able to write a bid before he left. He repaired the roof the very next day. I appreciate that someone answers the office phone so that I don't have to leave a message and wait for a response. The entire experience was very professional.

  • Patrick and his team are great to work with. Good quality installation and they left the yard clean of any construction materials. WestPro is clearly above the other companies that we interviewed for our roof work.

    Jonathan Hager
  • We had the pleasure of using West Pro for our roof, after speaking to and meeting with several other area roofers, the response we got from West Pro was by far the most professional and prompt. After the recent hail storms in the area, I expected West Pro to be very busy, the staff and owner were prompt and gave me the impression that despite this busy time for them, our needs were important to quickly address.

    Caitlin Dewey
  • WestPro did a fantastic job with a difficult roofing job that 3 other companies could not figure out. I highly recommend them!

  • Beck was great helping to deal with my insurance agency.

    Jennifer O'Brate
  • Patrick from WestPro was friendly, honest, and responsive. He identified that the leak on my deck was actually an easy fix that would cost $400 instead of the $2000+ that other companies had quoted. He fixed the problem that day in less than an hour instead of queueing up the work for weeks later. He also took the time to talk me through a separate issue and provide referrals. I can't recommend WestPro enough.

  • Owner Patrick Knackendoffel came to our home to evaluate a water leak which we thought may be a roofing issue. He did a thorough investigation including going into the attic where he found signs of condensation from the bathroom vent that was dripping onto the drywall causing the stain. Not a roof issue. Good diagnosis.
