We have used several roofing companies over the 30-odd years we have lived in our slate-roofed house, and Kaller is the... best of them all. They are pleasant, clean and professional. The quality of the work is top-notch. We will not use any other roofer.read more

The team, Chuck, Rich, Carlos, and Charlie was great. The guys were on time each day, worked diligently, and explained... what was going on each step of the way. Some potential issues that Chuck anticipated were in fact discovered; the team was responsive with providing materials and addressing the issues, without any delays. Carlos provided pictures when to show before and after conditions. The job was started and completed on time! Our neighbors have complemented us, saying they enjoy looking at the new roof.read more

I used R Kaller & Sons to install new roofs at my house (built 1920) and surrounding out buildings after seeing their... work on a nearby home. I am very pleased with the roofing and related carpentry work they did. It really looks beautiful. Project manager Chuck was very easy to work with, professional and highly experienced. Foreman Mike and his crew were great - friendly, courteous, always on time, and cleaned up at the end of each day on the project. I was very impressed by the craftsmanship and artistry of the cedar roofing work. A great job!read more

Since we bought our +/- 100 years old house, still with its original Vermont slate roof, the Kaller team has been on... site multiple times doing a variety of jobs ranging from full gutter replacement to copper dormer roof replacement, chimney repair and more. Chuck's assessment as to what was needed always seemed reasonable. The crews were knowledgeable, courteous and professional and executed the jobs in a timely manner. The quality of the work is excellent and competitively priced. Thanks to the Kaller team we are confident our beautiful slate roof will serve us well for decades to come.read more

I had Kaller come out and work on my porch roof that was handled poorly initially by another local contractor. From the... very beginning I experienced professionalism and true consultation throughout the process to consider each element the project, ensuring everything was handled correctly moving forward.Clint was the leading the job and was excellent in his attention to detail on each component of the project.Kaller may not have the lowest quote for the job but you are getting true professionals that don't take shortcuts.read more

Dont’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!

Michael Sayer

Our home’s slate roof and ice damaged gutters were in need of professional help. An exhausting search lead us to Kaller and Sons. Chuck made the whole process painless while Rich and Carlos’s high level craftsmanship along with quality materials yielded amazing results. We couldn’t be happier. Thank you gentlemen.

For many years, I have known and highly recommended Kaller Roofing to my real estate clients, learning each time that Kaller has delivered top-quality craftsmanship and impeccably excellent work. Recently, I had occasion to need them personally, and they were most responsive advising me of the best solution for the problem at this time. Ray Kaller is a most experienced/seasoned professional choosing his staff with that same resolve. If you are in search of a roofing firm which goes over and beyond to satisfy your needs, Kaller should get that call!
