Keller & Sons, LLC is a second generation family-owned home improvement company specializing in Roofing, Siding, Windows and Solar. We started as a “Mom & Pop” roofing company in 1980 working out of our Dad’s house in Flanders, with one truck and one roofing crew. We’re now one of the area’s most well respected small businesses with ten crews being directed out of our facility on Laurel Drive in Flanders. We’ve been here since 2004 and we’re not going anywhere, anytime soon! Brothers Mike and Dan Keller are partners in the business, having taken over from their Dad, George, upon his retirement in 2007. Both feel tied to the company with a huge sense of pride over the work that they do. Both Mike & Dan feel a huge commitment to doing the right thing for their customers, many of whom are repeat purchasers of the company’s services. With their commitment to the company and the Flanders area comes the knowledge that they’re not going anywhere. Their passion and drive to be the Premier Home Improvement Company in Northern NJ is reflected in their work ethic and their willingness to go the extra yard for their clients.

I would use them again in the future. **★★★★★ — Priscilla Densel, Jan. 2016** > George J Keller and Sons was recommended to us by another trusted contractor and also a coworker of mine. I’ve used George J. Keller for two roofing jobs now and been VERY satisfied with their work. They are thorough and their price has been moderate. The salesman was polite but not at all pushy. The work was done in a timely way and we were very satisfied with the outcome. We also had gutters and skylights replaced. I would highly recommend this company. ## Selected projects - [Mount Olive, NJ — GAF Charcoal Roof & Hardie Iron Gray Siding](https://www.houzz.com/hznb/projects/mount-olive-nj-gaf-charcoal-roof-and-hardie-iron-gray-siding-pj-vj~7195930) - Location: Mount Olive, NJ - Photos: 15 - [Port Murray, NJ — James Hardie Staggered Shake & New Decking](https://www.houzz.com/hznb/projects/port-murray-nj-james-hardie-staggered-shake-and-new-decking-pj-vj~7195904) - Location: Washington Township, NJ - Photos: 19 - Description: JAMES HARDIE - 7" SMOOTH - MONTERY TAUPE STAGGERED EDGE SHAKE - MONTERY TAUPE - [Randolph, NJ — GAF Charcoal Shingle Roof](https://www.houzz.com/hznb/projects/randolph-nj-gaf-charcoal-shingle-roof-pj-vj~7174504) - Location: Randolph, NJ - Photos: 9 - [Randolph, NJ — GAF Shingle Roof](https://www.houzz.com/hznb/projects/randolph-nj-gaf-shingle-roof-pj-vj~7174358) - Location: Randolph, NJ - Photos: 9 - [Basking Ridge, NJ — James Hardie Arctic White Siding](https://www.houzz.com/hznb/projects/basking-ridge-nj-james-hardie-arctic-white-siding-pj-vj~7174344) - Location: Bernards, NJ - Photos: 11 - [Randolph, NJ — Charcoal GAF Roof](https://www.houzz.com/hznb/projects/randolph-nj-charcoal-gaf-roof-pj-vj~7174352) - Location: Not specified - Photos: 8 - [Flanders, NJ — Certainteed Monogram in Herringbone](https://www.houzz.com/hznb/projects/flanders-nj-certainteed-monogram-in-herringbone-pj-vj~7152329) - Location: Mount Olive, NJ - Photos: 18 - Description: This home previously had a roof replacement with GAF Timberline HDZ in Barkwood.
