"I would strongly caution anyone considering this roofing company. We had our roof redone in July 2025, and by February we experienced water damage inside our home. After inspection, the issue appeared to be related to poorly installed flashing around a vent. Instead of taking accountability or even seriously investigating the workmanship, the company quickly dismissed the problem and claimed it was caused by an animal, therefore not covered under their warranty. This was disappointing, especially given how soon the issue occurred after a full roof replacement. A reputable company should stand behind their work and be willing to thoroughly assess potential installation issues rather than deflect responsibility. The lack of accountability and unwillingness to help resolve the damage left us dealing with repairs on our own. Based on our experience, I would recommend looking elsewhere if you want a company that stands by the quality of their work and provides reliable customer service."

"Amazing follow-up by by Darren Kretzer. I had Attic Construction treat my property last year. When I had a recurrence of issues (rodents) this year, I contacted Darren and he came out the same day and took the necessary time to identify and remediate the problem the same day. Excellent Service! I would not hesitate to refer them to all of my friends and family. There work exceeded all expectations."
