Client Testimonials

Don’t take our word for it – here’s what our clients say:

Kaller Roofing rebuilt our fiberglass roof deck that was leaking in multiple places. They provided expert guidance leading up to the job, and did impeccable work. The crew were very professional, and the owner himself checked in multiple times to assure quality. Our new roof deck is not only more functional, but looks much better and will be a great space for years to come.

Mike O’Hara

Excellent workmanship, high professionalism in the entire crew, especially the foreman, Mike Austin. They were prompt, kept us apprised of the progress, excellent site cleanup at the end of each day, and upon job completion. Beautiful result. Will recommend to others. This is the second time Kaller has roofed our house, our experience 30 years ago brought us back this time.

Rob Nelson

Fine work. A great team. The guys (Rich, Carlos, Jake and Justin) were conscientious, professional and talented. It was a large job from a home owners view and they handled it well with an attention to detail. Hats off to Chuck and Ray also for their supervision and support. This twin is 120 years old and with care like this it can go another 120 years.

Jim Shugart

The roofers explained everything beforehand and were very prompt each day. They appeared to be very knowledgeable. We had a very bad experience with another roofing company and Keller was certainly much more professional and trustworthy. We will definitely use Keller again if we need a roofer.

I am the facilities manager of a large church in Greenville, Delaware. Kaller Roofing has been our roofing partner for over five years, and I highly recommend them. Ray Kaller is a skilled and experienced diagnostician, which I think is the most important part of the process of getting to a solution. The members of his team are also highly experienced and easy to work with. Give them a call!
