  This review is long overdue. As a local general contractor and roofing company owner, I truly appreciated the opportunity to work with DE Group. They took care of our team, communicated well, and worked with us in a way that felt fair and supportive from start to finish. They were a pleasure to work with and handled any issues or concerns more quickly and professionally than many companies we have dealt with in the past. Thank you guys!

  We just had our roof done by DE Group Roofing and couldn't be happier. Mark was fantastic to work with, he comes from a family of roofers and clearly knows the industry inside and out. From the very start, he was transparent, honest, and informative, walking me through every step of the process. The team showed up on time, worked quickly and efficiently, and the pricing was very fair compared to other quotes I received. They installed anti-bird spikes and even added extra at no additional charge. What really stood out was how professional and considerate they were with my home. The project was completed smoothly, with no surprises. If you're looking for quality work, great pricing, and a company you can trust, I highly recommend Mark and DE Group Roofing.

  I just had my roof replaced and thought the process was fairly easy. I did have trouble finding the right color of the shingles but had help from Mark in selecting what would look best on my house. He was totally right. The estimate was …
