I had a leak, and got ahold of Nate. Nate showed up the next day, tarped the leak and had a crew for a permanent fix out within the week.
Cost was clear, quote was accurate, and the work was completed in a timely fashion. No BS, no scammy upselling, just fixed what they needed!
Very happy.

This past September, Koontz Roofing replaced my old roof. They have recently done several new roofs in my neighborhood. Every homeowner I contacted was totally pleased with the price and quality of their work. I can now say the same. Koontz Roofing did a great job. They are courteous and professional in every way. I highly recommend them.

Koontz did a thorough, excellent job replacing wood panels, vinyl siding and roofing. They came in way ahead of their own predicted timeline and we were very pleased with their work.

So glad I found Koontz when looking for window replacement. My sales contact was responsive and knowledgeable, the installation lead kicked it up another notch when scoping out, measuring and finalizing the job, and then when the installation crew stepped in once the windows arrived, it was a home run. They were great to work with! Professional, friendly, knowledgeable, experienced reps from start to finish. Highly recommend Koontz Construction!

After calling 2 different roofing companies and not getting anywhere, I called Koontz. They immediately got me on the schedule. When Adam (estimator) came out he went above and beyond to ensure my roof was in top shape. He was, helpful, friendly and knowledgeable. I should have called Koontz first, I won't make that mistake again.
