Roofing Experts Who Provide Quality Craftsmanship 
Residential, Commercial, and Historical Buildings.
Serving Pennsylvania, Delaware and New Jersey

We recently had the roof on our historic house replaced by Kaller roofing and we were very pleased with the level of service and degree of craftsmanship from the team. The project manager, Chuck, communicated with us regularly and was frequently on site as was the owner. Our roofing team (Rich, Carlos, Charlee, and Angel) was not only very skilled but also very professional throughout our complex three week job. Kaller Roofing is a small family-owned company with employees that have been with them a long time-a fact that gave us peace of mind for such a big home project.

Kaller Roofing did an OUTSTANDING job of fixing our aging rooftop, gutters, flashings and drains! Chuck Keller and his crew (Mike and Rich) were fabulous. Chuck schooled me in all aspects of roof restoration, and his team worked hard through the coldest winter of this century!! The end result was beyond great! Friends and neighbors have commented on how impressed they are with the quality of the work. THANK YOU!

I needed complete roof replacement down to the original boards on my main roof and three sub-roofs. My new roofs were a 3 layer modified bitumen system with a white granule top sheet. I received new copper flashing at walls and new copings throughout. The quality of the work was top notch. The work crew were the same guys over the four long days so I saw consistency and great workmanship throughout and particularly around roof penetrations. The waste from the old roof layers was disposed off daily into dumpsters with a good clean up at the end of each day. They also removed an old unused brick chimney stack and roofed over the opening. Roof pitches (slopes) were corrected and made more positive towards the drains.

This is the second of two very good experiences with Kaller Roofing working on my 100-year-old slate roof. This job, Rich, rebuilt a lower section of one roof and flashed and covered the many vent pipes. He was professional, knowledgeable, timely, diligent, and explained his work throughout the project. And Ray, thanks for stopping by. When my next roofing need arises, I will be calling Kaller.

If you admire the architectural quality of some of the most historic and important structures in Philadelphia and want it for your own dwelling Kaller Roofing is your contractor. The quality and attention to detail is evident throughout their projects. Their craftspeople are experts in their field and highly trained. The process from estimate to completed install was highly professional and easy to follow. They arrived early and completed the job on-time. We highly recommend Kaller Roofing.

Very pleased with the workmanship and the quality of the service provided. Have had work done by Kaller several times in the past and they have always done quality work, been on time, and completely explained what was going on.

On the last occasion, they were here, they replaced the flashing on the valleys along with some additional. issues. Mike and Rich were here early, got the valleys replaced before a rainstorm stopped work. The job was timely completed and has withstood some major storms to date.

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.

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.

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!

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.

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!

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.
