"Professional, Responsible, and very knowledgeable. This combination is becoming more and more difficult to find these days. Dennis is a man of his word. I am extremely impressed!!!"
"This company does not stand by their work. We purchased a home with the roof done by this company 7 years ago and there are already numerous leaks that they will not repair without charging an arm and a leg. Already have another company coming out to diagnose free of charge, when Dennis wants $375 just to diagnose his own issues. Good contractors stand behind their work, this one does not. **UPDATE** this was purchased through the Previous owner, not myself as I would not choose a company with an owner that is so rude. Luckily, we hired a very reputable company to fix your issue."
"Just called them and they don’t do free estimates/diagnostic...$375, unheard of . WoW"

- "After 9 years of hurricanes, ice dams and falling tree branches our roof had raised shingles and pieces of plywood that had shifted out of place. Dennis and his team were highly professional and did a wonderful job securing everything down again, extending the life of our roof and making it look great in the process. I would highly recommend Harmony Home Improvement and will certainly use their services in the future."
- "I’m giving one star because the beginning was ok. Estimate guy was on time, explained everything, all the pieces seemed to be in place. Also they worked with us in terms of rescheduling the installation of the roof. Pricing wise they’re average with everyone else. Now the day of the installation. The dumpster and materials supposed to be deliver first, instead group of guys showed up and started ripping my roof in 22 degrees weather (no dumpster or shingles on site). None of them speak any English to get any explanation. They worked long after dark with flashlights on their heads. I saw the results in the morning when I found my driveway covered in old nails, and front gutter smashed in two spots. Hubby gets in the attic and see the sky in two different places (no flashing on connecting roofs), no ridge vents which according to estimate guy are mandatory and included in price Called them and one guy came back and supposedly fixed it (didn’t have chance to check it yet). Also got extra bill for 16 sheets of plywood replaced (which could be true, my roof was old), but it would be nice to see some kind of receipt/proof of that. Lastly, I had to call the dumpster company for the dumpster pick up cause they just left it behind. After two days of waiting I figured nobody is coming to get it. Sure enough dumpster comp had no clue about picking up their container. I also had to clean my neighbor’s yard covered in plastic shingles wrappers In nutshell, If I could go back I wouldn’t go with them..."
