The situation

What Brought Us to Stonegate Circle

The homeowner contacted us after wind damage caused several shingles to blow off their two-story home. The existing composition shingle roof was approximately 25 years old and had reached the end of its expected service life, making a complete roof replacement the best long-term solution.

The solution

What We Did

Our team removed the existing 25-year-old roofing system and installed a new GAF Timberline HDZ shingle roof. The new roofing system provides improved protection against wind and rain while enhancing the home’s appearance and long-term durability.

Scope of work

Top notch all the way around. Kevin did a great job on initial assessment and explanation. Dean was beyond excellent in talking us through every detail and answering all my newbie questions. Guessing not many people probably buy more than one roof in their lives, so it’s a learning process and Dean was great all the way through. He facilitated getting us samples of a dozen different shingles to choose from for color. Threw in some extras on installation that were not on the quote to make us happy with the details. Price quoted was the best we got, including no markup on permit fees. And without doubt best service you could hope for. His quote was also the only one with thoroughly detailed info on methods and materials. Most others were just a single line lump sum “trust us” kind of quote. But for $20k you might want some details! Dean delivered. Also certified for the best warranty in the business. Lots of other business charge extra for that, Acker included it in the cost. And lots of other installers advertise or say that they’re certified with various shingle companies, but surprise, they’re not! Buyer beware. I called and emailed the manufacturer to verify after getting quotes, and most weren’t authorized to offer the extended warranties. But if you didn’t check and then 20 years later you need to make a claim, surprise! Peace of mind, Dean and Acker are fully legit. Plus, Dean is a straight shooter no BS kind of guy, not a pushy salesman. Acker truly earn all those 5 star reviews, now including mine. Thanks guys!

Acker Roofing was a great choice. Dean Mouser’s quote was the second lowest out of 6. The lowest quoted company only had 10 reviews and 4 were horrible. Acker roofing has hundreds of 5 star reviews. Acker roofing did a great job for a reasonable price, and also updated the vents for a more sleek design. The roof looks great and is prorated for 30 years. Will recommend them to anyone I hear thinking about roof replacement.

Acker Roofing did a great job of replacing our roof. They listened to my specific needs, found a good solution, and troubleshooted problem areas. They were able to fit us into their schedule and the job was done quickly. They handled all the permits and inspections and provided me with a letter on letterhead that was easy to show my insurance company to prove we had a new roof. Great quality product and service. Would highly recommend.

Dean and Acker came recommended to us by a State Farm insurance agent, and we can see why. Dean quickly turned around a fair quote for roofing our house. Rodigo and his partner worked diligently on every detail of the job. Their professionalism was evident as I watched their efforts. We feel really good about the work done on our home.

We were extremely pleased with both the sales and the implementation experience. The quality of workmanship was top notch. We strongly recommend Acker and will use them again. In particular the Sales manager Dean was amazing to work with

We had a large pine tree fall on our home and feel incredibly fortunate we chose Dean Mouser and Acker Roofing over the big companies with flashy brochures and slick sales pitches. Dean was knowledgeable, honest, and guided us through every step—assessing the damage, navigating the insurance process, selecting the right materials, and answering all our questions. He never pressured us and only moved forward once we were comfortable. He was responsive, reliable, and followed through on everything he promised us. His crew showed up on time and delivered high-quality work, completed efficiently and professionally. We’re extremely happy with the results and highly recommend Acker Roofing.

I live in North Carolina but I needed to take care of my dad property after he passed. I contacted several companies some of which did not call me back. Dusten at Acker called me right back. He inspected the roof and sent me a written proposal right away. Acker gave me a fair price but more importantly they did a phenomenal job. They made the process very easy despite the fact that I was almost 3000 miles away. Dusten communicated with me via email, text, and phone and answered all my questions. This is a company with a lot of integrity and they do exceptional work. I wish I could hire them here in NC! 😀

These guys did a good job at a fair price. I called six different companies in the area, they were the most reasonable reputable company of all six I’m pretty happy with the situation. Their guys cracked a little plastic mini roof while they were working, and I told him about it, and they came out and fixed it immediately. The roof they put on looks like it’s gonna last a long time. Thx Acker

They were responsive and did a great job with the work needed on our roof repair! It took longer to finally get scheduled, but they responded and provided updates when needed. Before and after photos attached!

We did a complete tear-off and also had insulation blown into the attic. Dusten and his team, both office staff and crew, were professional, detail-oriented, patient and polite. Our old house has some peculiarities, but Acker Roofing rolled with it and got the job done fast and with precision. After an encounter with another roofing company, who shall remain nameless, Acker Roofing restored my faith in humanity. I would definitely recommend them to anyone wanting their roofing done right!
