Denny is professional and responsive, two traits I value when working with a contractor. Denny has managed two major projects for me over the last few years - the first being replacement of our hail damaged roof, and the second being a repaint of our house. He and his team did a thorough job on both occasions. When the work was done each time, Denny performed a walk-around with me to ensure everything was done to my liking. Pleasure to work with and highly recommend, thanks!

We bought a house recently and during the purchase inspection it was noticed that the roof had significant hail damage. We had Denny's Roofing come out to do the replacement work. I was extremely pleased with their work and the results. It was a quality job, done professionally. There were some issues both with the Insurance company and with how the original roof was done. Denny came in and drove every item to successful resolution. He was outstanding. I couldn't have been happier with how thorough and complete a job he and his team do. Great work! I would hire them again in a heart beat to do my next roofing project.

Denny runs a great business, operates with integrity, and communicates proactively. Our home roof replacement went without issue and Denny made certain we were happy with every aspect of the process. I would highly recommend Denny's Roofing!

Denny and his team of roofers, along with his contracted painters were awesome. I never had to wait more than a few short hours to receive a reply via text or email, and he was perfectly descriptive and upfront about all expectations and costs. His team moved fast and had the entire roof on our two structures replaced in one day. The painters sanded and caulked where needed and painted the house in just a couple of days, which impressed us considering how clean of a job they did in that short time! Perhaps not to be overlooked, was how prompt and thorough he was in dealing directly with our insurance company. He made the new roof and house painting so painless and easy, I cannot imagine having gone through this with anyone else.

I'm a detail oriented guy and when Denny put a new roof on my house he put me completely at ease. He always kept me in the loop with what was going to happen and when. He and his crew did a great job and I got a great roof at a great price. As if that's not enough, two years later Denny was driving through my neighborhood and noticed a couple of shingles out of place. He knocked on my door and asked me if he could fix it for no charge - what more could you possibly ask for…

Denny and his crew did an outstanding job on the roof, paint for the exterior of our house and replacement siding for only the area that needed it. He didn’t try to oversell us on more than we need. They were all very professional and polite, and the price was very reasonable. We highly recommend Denny’s Roofing.

I had my roof and skylights replaced in April 2021 by Denny’s Roofing. From Day 1 I was impressed by Denny’s thoroughness, warmth, and professionalism. He was meticulous with the insurance claim and because of his persistence with the adjusters, succeeded in getting me a claim that completely covered the replacement of the roof and skylights. He was patient, provided referrals to subcontractors for windows and skylights, and met with everyone involved multiple times to make sure that this more complicated job would go off without a hitch! I couldn’t be happier with the process and the final product. I highly recommend Denny and Denny’s Roofing!

I have worked with Denny twice now for full roof replacements due to hail damage. He has consistently been easy to work with and went to battle with my insurance company on my behalf to get the funds I required. He goes above and beyond to ensure our complete satisfaction!

Denny was fantastic to work with. He was punctual and very knowledgeable when we had to replace our roof due to hail damage. He was always available to answer questions and go the extra mile to make sure we had a great experience. When our solar panel company damaged our new roof he came over to do an assessment of the damage with no questions asked. I would highly recommend him for any work you need done.

Denny was very helpful - communication was excellent. Professional +++. Our new roof looks great and has handled this very rainy spring with flying colors! After the roof was installed, Denny came back to diagnose a leak in our garage near the entry door. We took his advice and my son was able fix the problem ASAP!

Have used Denny twice to repair a hail damaged roof - highly recommended for all roof work! Professional, on time, super-responsive and helped me navigate the insurance claims too. Local company with local roots - not one of those storm-chasing outfits from out of state. Be smart - go with Denny.
