    I spoke to John from Barth roofing and I emailed them stating I needed “ALL” roof sidings replaced and when come to find out they didn’t change all sidings out. I emailed Jon and he stated they did the work he estimated for which are the barge rafters and I had stated “ALL SIDINGS” and emailed him pictures and he stated those are Facia boards! Excuse me you are the professional not me to know the names of these items. I was under assumption per his estimate and my clear conversation and email that “ALL” sidings would be included in his estimate. Miscommunication on their part was horrible and no resolution has come about this. Images were submitted to him and showed him they even changed some so called “Facias” and asked why would they change some and not all. Very Disappointed with these repairs.

    I tried several times to request someone to come out and give me an estimate for a full roof replacement. Crickets. I moved on to someone else.

    Keven arrived EARLY for his estimate of repairs I needed on my 35-year-old roof. Only new plashing and gaskets for roof vents were needed. Great price was offered after he showed me photos of the problem areas. Two days later the tech …

    Awesome service! I had to get my roof inspected for insurance. Barth Roofing was able to send someone out within 2 days. Keven showed up on time. He was kind and professional. After the inspection the office sent me photos of my roof and a letter of certification that I was able to send to my insurance company. Would definitely recommend!

    I recently called Barth Roofing for a full roof replacement on my home, and I couldn’t be happier with the results. From the very first call, their team was professional, responsive, and easy to work with. The sales rep. Keven took the time to explain all of my options clearly, and answered every question I had and provided a fair quote.

    Barth Roofing is a fantastic roofer. They kept me informed of the process of the project. They support Veterans organizations and are prompt to respond with information. I'll contract with Barth Roofing in the future.

  • 5 out of 5Ana Silva2 years ago

    Got a quote in 2 days. The person was professional, kind and knowelegable of what my roof needed and why. My neighbor got his roof done by barth and it looks great. I found them to be fair in cost.

  • 5 out of 5Joshua Brown3 years ago

    It was New Years weekend, and I noticed some water stains starting to form on my living room ceiling, right above my TV. This was also a weekend off historic rainfall and winter storms. So I had to wait an extra day for businesses to open back up, and then I called every roofing company in town to try and get someone out to my house to fix this leak. Other companies gave me wait times from one week to one month, Barth offered to be at my place in 48 hours. So the roofers showed up and had my roof repaired in about 15 minutes. I had a broken tile on my roof, they took pictures and showed me the before and after. I can confidentiality say that Barth roofing is the best company in town. They are professional and if it's an emergency they will not keep you waiting.
