Client Testimonials
Don’t take our word for it – here’s what our clients say:
During a storm last year, we unfortunately had a large tree branch that pierced our roof, ripped off gutters, and damaged cedar siding. Chuck and his team at Kaller did an excellent job repairing the damage caused so that you would never know there was a problem in the first place. The shingles matched our existing 20-year-old shingles perfectly and they matched the bead on the new cedar siding exactly. I would highly recommend Kaller for all roofing needs.
Shane Gregory
Kaller has been taking care of our slate roof since we moved here in 1987. They’ve always been fair with pricing, and have done excellent work. This last time Rich, Carlos and Charlie were on the job. When they went up on the roof to do some repairs on the 3rd floor dormer, they discovered that the problems, which weren’t visible from the ground, were much more extensive than originally anticipated . They took photos and showed us what needed to be done. They did a great job as always, and we were very glad that they saved us from water damage and expensive repair work down the road.
Michele Geraghty
We had our roof and gutters and some siding replaced thus winter. Final product looks great. We had some rotten wood and a few tricky areas that needed carpentry work and they were to handle all of it. Everyone was professional and courteous throughout. Big thanks to Chuck, Rich, Carlos, Charlie, and Angel. I highly recommend Kaller Roofing!
Benjamin Thomas
Ray Kaller and his colleagues recently completed a large slate roof/flashing/coping/ gutter job on our 100 year old Vermont Slate Roof. Their attention to detail and professional explanation of the issues were great. I would highly recommend the Kaller and Sons team.
Amanda Friz
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
I am very pleased with the new roof, gutters, copper flashing and concrete chimney crown installed by Kaller Roofing. The roofing team (Carlos, Rich, Charlie and Angel) were extremely profession and definitely experienced in their trade. Carlos keep me updated daily and made some excellent recommendations. I will positively recommend Kaller & Sons to anyone who is looking for a top of the line total roofing project.
