  • "Unreal job on my roof. Guys showed up on time, worked hard, and did the job under quote. Couldn’t have asked for more. Appreciate the work. Will highly recommend!"

  • "First, we are pleased with their transparency (itemized list with specific products, explanation of process, etc.), simplification, quality workmanship, and professionalism. Second, we appreciate their reasonable pricing. After doing some research, we were persuaded to use Owens Corning shingles. We searched the manufacturer's website for contractors and contacted a couple of them for quotes. Not only did Sentry have the highest rating (Platinum Preferred Contractor) from the manufacturer, their quote was only 56.5% of a quote given by a competitor. Of course, this left me a little skeptical, so I created a spreadsheet for a side-by-side comparison. Nearly every line item was identical. The couple of differences (e.g., ProArmor synthetic underlayment vs. Owens Corning Rhino) were products of the same quality (or arguably better) and rating. Actually, the underlayment they installed is priced about 15% higher than the other at a major retail store. Finally, their customer service is great. Drew stopped by our home, answered our questions, and provided us a detailed quote. In fact, he came out a second time to show me samples of the actual product (instead of just pictures in a catalogue). Even though our scheduled install time was during several consecutive days of rain, they kept us informed throughout the process. They divided the project into two consecutive half days to keep things moving along. Brett and TJ were very thoughtful and helpful. It is quite a relief to have this major project completed. And it’s also a nice feeling to walk away feeling confident in all aspects of the decision – the materials, workmanship, and value."

  • "Everyone at Sentry where professional and great to work with. They did a fantastic job. The crew was very professional. We will use them again for other projects."

  • "Terrible customer service. VERY difficult to work with if looking for a just a repair. No one answers the phone during business hours. Employee voicemails are constantly full, online quote system errors out, emails ignored or incorrect email address listed on invoice. Overcharged for tarp placement and left debris. Friend had given me their name, should have read the reviews first. Going with better company to finish this job and 2 large upcoming replacement projects on my other properties."

  • "I was told my metal garage roof was short and it could be repaired and leak free by bring the existing metal down and adding flashing. When the roofers arrived they asked to borrow my ladder. One of them spoke to me and was very skeptical about the repair and stated the metal would still be short. I called the office and spoke with T.J. who was quite rude and said he was pulling his guys out that this job was too much of a problem and he did not want to do it. He was yelling and it was upsetting. I called and spoke with Paul who said some similar things as T.J., but did say by the end of the call they would return and do the job. I had to leave to pick up my dog. When I came back the roofers were gone and the job was not complete. The metal was short and sticking up/not nailed down in a number of places. They have refused to return my calls, texts, and emails to complete the work. It is very frustrating and upsetting and likely could be resolved if they would communicate. I sent communication to the BBB but they were unsuccessful in resolving this too. I hope no one else has to deal with this issue. I will probably have to hire another company to complete the work sadly. Beware of this company. They are not interested in providing customer care or working with the customer."

  • "My review is just about identical to the one left by previous reviewer Thompson. When I contacted Mary at this company she PROMISED someone would be here Thursday 2/25 for an estimate. Foolish me believed her as she appeared to be sincere. Late morning on Thursday I contacted her to be sure someone would be coming and again she assured me they would. Around 12:30 PM I contacted her again since no one appeared as promised and she again assured me someone would be here. I explained I can't waste another 4 hours waiting for a no show. She then said go do what you need to do? So I am supposed to only do local errands because they are inept? Told her that would not work. She then promised someone would be here Friday morning on 8/26 - as you are probably guessing again a no show. Called Mary multiple times explaining my time is at least as valuable as anyone's at their company. I let her know I am also a business owner and had now wasted 2 full mornings waiting for people that I believe Mary knew full well wouldn't show. She said to go out - again I explained when I go out it will not be local but then I relented when she said again that she promises Dave will be coming out and will give me a 30 minute heads up when heading my way. End result is I wasted and waited over 13 hours for repeated NO SHOWS. When a company can't be bothered showing up or be responsible and professional it is a big RED FLAG that there are many other issues than shows plaguing this company. DO NOT BELIEVE A WORD THEY SAY!!!"

  • "Called them to have someone come by and quote a new metal roof, made appointment for the afternoon on Wednesday and was told someone would call before coming, needless to say no call or visit. Called today to complain and was told I would get a call with answer to the no show, which never happened and told someone would come by today which again no show. Definitely would not use this company as others I've interacted with responded promptly."

  • "This is a fantastic company to use. They were neat, prompt, courteous and hardworking. We had a large commercial roofing job that they did for us. They did the job they said they would do and exceeded my expectations! Highly recommend!"

  • "I reached out via email for a quote, received a follow up within 24 hours. They had a knowledgeable representative on site within 3 days to look at the roof of my garage that needed shingle replacement. The appointment was scheduled for about 3 weeks later, which was satisfactory as this was not an urgent need. They kept me informed the week before of the exact date of arrival, and were on site that morning. The job was finished that afternoon and looks fantastic, exactly as needed. Efficient and no cleanup required. Thanks again!"
