Here are 3 areas we recommend you consider in evaluating every remodeling contractor you talk to: 1.The Reputation and Business Stability of the Company 2.Their Experience and Methodology 3.Their Service before, during and after your project I encourage you to carefully review our site and then call us at for a complete copy of our consumer guide and step-by-step installation process prior to our meeting.

"George J. Keller & Sons are highly recommended. When Dan visited our house for an estimate he explained our options very well and is the nicest guy. A personal webpage kept us updated on our schedule for the roof installation. Materials and dumpster were delivered on the morning of installation and promptly removed when the job was completed. The employees were very neat, the company very professional and the roof looks fantastic."
"The team at George J Keller & Sons were great to work with. We contracted with them to replace our roof and siding and are very happy with the results. They were prompt, responsive, and completed the work well within the contracted dates. I recommend them to anyone looking for a great contractor."
"I'm incredibly happy with the roofing and siding job Chuck, Carlos and the other members of the crew just completed. A friend recommended Chuck to me and she was right. I'll bet even the market price of my home just improved. Thank you, guys!"

- "I purchased a home with a roof that was at end of life. After receiving several estimates and doing a bunch of research, I decided George Keller was the right company for my project. A roof is a big investment and needs to be done right. Being a GAF Master Elite contractor gave me the extra confidence I needed. While they were not the cheapest option, they were the best option. The product, service, and install was worth every penny. From the first call to meeting with Carl to the install, everything went great. The crew was friendly and professional. There were daily site visits from supervisors. They cleaned everything up. The roof is beautiful and leak free! I could not ask for more and highly recommend George Keller & Sons roofing."
- "Excellent siding work on our home. Beautiful trim and columns provide a nice finishing touch. They did exactly what we wanted and in a timely manner. We've stopped counting the compliments from our neighbors."
- "We used Keller for our roof installation. Despite a shingle shortage (due to COVID 19) the roof was completed in one day! We were impressed by the speed, and professionalism, and the quality. Well done!"
- "The Keller team set a date to do the new roof and ridge vent install.they first set up barriers to prevent damage from the old roof tear off and proceeded from there. Any questions I had were promptly answered as the work continued. When we neared the finish they began cleanup of the site removing debris and loading it into the provided Dumpster. Final cleanup included magnetically picking up nails that may have fallen during job. The roof on the house and garage were completed in one day and the Dumpster was removed the next day. I was very pleased with the work and the team that did the work Al Demarest 3 Brook Lawn Drive Long Valley NJ"
- "Mike installed my roof a number of years ago....had a minor problem, and mike and his crew was there to fix it. Hard to find men of integrity that are professional and stand behind their work. Mike Keller and his team are tops in my book"
- "After putting it off for many years, we finally did it and we’re so happy with how everything came out. We had George Keller & Sons install vinyl siding and replace/upgrade our 5” gutters with 6” ones. Everything came out great and we’ve received many complements from family, friends and neighbors on how amazing it all looks. We love the charcoal gray color siding that we chose, how our bay window looks now that its bumped out a bit with a dark metal roof, and the headers they installed above our front and garage doors. Thanks for a job well done, George J. Keller & Sons!"
- "After soliciting bids from multiple GAF certified roofers, George Keller & Sons provided the best price with zero hidden costs, explained the whole process from start to finish including timeline, delivered and installed as promised. Selection and styles offered were extensive which the end result looks great. Overall they were fast, professional, courteous, and wanted nothing more than my acceptance of the work being performed and after completion. They absolutely left a strong positive impression. Although I hope I don’t have to use them again (I mean that in a positive way) but if I had to, George Keller & Sons will be my go to roofer."
- "I have to say that I was VERY impressed with this company, as were my neighbors who watched the whole process. Brendan the salesman was so helpful and knowledgeable and honest! The roof crew was fast and thorough. They did everything they said they would do on schedule. The entire job only took one day! We had neighbors stopping and saying how amazing it was to watch a roofing job being done so organized. They also spent a lot of time cleaning up. I'm very happy with my new roof and skylight!"
- "I had a very unusual issue with mold created by another contractor who had done work prior. From a referral to mold remediation, inspection of what was causing problem to helping settle the issue by writing a dual contract one for half of roof that was effected by other contractor, the other half that I needed to replace (can't have a half of a new roof), the support I received was far beyond expectations. The crew were courteous, fast and cleaned up so well. Highly recommend this Company. Cindy Washington, Warren County"
- "I've lived in my home for 27 years and had the pleasure of using George J. Keller & Sons twice. First when we moved in they put a second layer of roofing on my house and again when that had to be replaced a few years ago they were the first and only call I made. They are always professional and have been very responsive over the years. When I thought there was problem with the roof they came right out and inspected it. I will definitely think of them again when we are ready to side our house as I know they will give me a fair price and do a professional job."
- "George Keller & Sons installed a new roof for my parents a few years ago and they were extremely happy with them, so I hired them for my new roof. They were very informative during the whole process and did an exceptional job. I would highly recommend them."
- "George J. Keller & Sons just replaced our roof, 6/2020, and we are so pleased! We had gotten quotes from three different roofers, and - of the three - Keller's was reasonable and fair for the high quality business practices and workmanship standards that they uphold. They updated us regularly for the timeline of when they were coming out, the work was done within a few hours, and any questions we had were addressed promptly and to our pleasure. The roof also looks great! A job well done!"
