Customer Reviews

"Hired by contractor during flip that we purchased in August 2020. Replaced entire flat roof with PVC material. Started leaking in April 2021. They tried to not find our job in their records saying they got a new system and can't honor their 25 year warranty. Since we never got the opportunity to see a receipt cause the contractor hired and paid for the job as part of our purchase negotiations, luckily our realtor tracked down copy of the check in our home purchase papers. After proving they did the job, they came out to fix it after a week of trying to get them to make an appointment. Finally came through is better than nothing 😏."
"Professional, timely, honest, and competitive prices. I highly recommend the team at National Roofing for any of your roof needs!"
"The company came recommended from a realtor friend who had reported good experiences with other clients. I received a nice packet of info about the company which initially impressed me. The salesperson came out and was knowledgeable and recommended Gaco product for my roof and gave me what I thought was a very fair price. I had already talked to a couple other companies and felt comfortable so I signed an agreement on Nov. 1 2016. They said it would be a few weeks before install and products showed up on my roof shortly after. After the materials sitting on the roof for several weeks there was a truck at my house to take the products back, and the driver said it was too cold to do the job before winter was over. I was upset since I had been led to believe it would be done before it got too cold. I understand the product has temperature limitations, but it was a mild early winter and I was also told there were "two jobs ahead of mine" when I signed the agreement. I waited until the winter passed and weather was agreeable for the work. Again I called and was told there were "two jobs ahead". Waited and waited, called back and now there were "three large commercial jobs" ahead of me. Now in May of 17 still no installation date 6 months after signing contract. At no time did the company make an attempt to call me, I always had to call their answering service and wait for a return call. I found Schneider Roofing and they are doing the same work for the same price, and have a great reputation. Plus they actually showed up to do the work. I would never call this company again, they are disorganized and do not seem to care about the customer."
