Roof Replacement
Our roof replacement service combines decades of expertise with manufacturer-certified installation techniques. We conduct comprehensive inspections using drone technology and attic assessments to identify structural issues. As GAF Master Elite contractors, we offer exclusive warranty protections and use premium materials designed for Northern New Jersey's climate. Each project includes ventilation optimization to enhance energy efficiency while maintaining aesthetic appeal through custom color matching and material selection.
Metal Roofing
We install durable standing seam metal roofing systems certified by Englert. Our on-site fabrication ensures perfect fit while Kynar-coated materials provide 35-40 year finish warranties. The energy-efficient design reflects 80% of solar radiation, reducing cooling costs by up to 30% while maintaining architectural integrity through customizable color options and seamless integration with existing structures.
Siding Installation
Certified James Hardie and CertainTeed installations feature fiber cement and vinyl options with ColorPlus technology. Our crews implement climate-specific HardieZone systems that resist extreme weather conditions. Each project includes trim replacement and window integration for cohesive aesthetics. We maintain 10-year workmanship warranties while offering specialized options like board-and-batten and cedar shake alternatives for custom architectural styles.
Window Replacement
Andersen-certified window replacements include energy-efficient vinyl, wood, and fiberglass options. Our master carpenters ensure proper fit through precise measurements and structural assessments. We coordinate simultaneous siding replacements for seamless transitions while maintaining strict compliance with local building codes. Each installation includes weatherproofing treatments and custom trim work to enhance thermal performance and curb appeal.
Gutter Systems
Custom seamless gutters are fabricated on-site using heavy-gauge aluminum for leak-proof performance. We offer gutter guard systems to prevent debris accumulation while maintaining proper water diversion. Each installation includes downspout extensions and splash block placement to protect foundations. Color-matching services ensure visual harmony with existing roofing materials while maintaining optimal drainage capacity through precise slope calculations.

George K. Keller and sons changed our roof twice (once in our previous house and once in our current house). We could not be happier with their services - they are very professional and efficient and kept us well informed. Can only recommend them. Services: Roof installation, Skylight installation

Report
Keller and sons recently installed new gutters and reroofed our back roof which had started leaking. I was very impressed throughout the entire process Amanda was very detailed and thorough with the estimate, the installers did great work and left zero mess. Would absolutely use them again and recommend there services to anyone needing gutter, roofing, or siding work done.

Report
The folks at Keller were a pleasure to deal with. Their quote was very close to two others I solicited, but was by far the most complete in explaining what it included. Their work was great. With the new roof and gutters, the house looks like new. For the most part, they were timely and cleaned up well and the people in their office were very responsive to any questions or concerns. Highly recommended.
