Sigma Development Group

Sigma Solar & Roofing is a roofing and solar contractor based in Livingston, NJ, serving homeowners across Essex County and the surrounding North Jersey region — Montclair, Maplewood, West Orange, South Orange, Bloomfield, Newark, Livingston, Belleville, Nutley, Glen Ridge, and the towns around them. Our work is concentrated in three areas: residential roof replacement, roof repair, and solar panel installation. As a GAF Certified contractor, we install roofing systems that qualify for extended manufacturer warranties — coverage that non-certified contractors cannot offer. Essex County's housing stock is unusually varied, and that variation drives how we approach each project. The methodology for a slate replacement on a Victorian in Montclair has little in common with an asphalt re-roof on a colonial in Livingston or a flat roof on an urban property in Newark. Roofing is not a templated trade, and we don't treat it as one. Services include full roof replacement and tear-offs, asphalt shingle systems, metal roofing, flashing and ventilation upgrades, storm damage repair, drone-supported roof inspections, residential solar installation, and insurance claim documentation. Every project begins with an inspection. The objective is a clear, accurate assessment of the roof's actual condition — not a sales pitch. If a repair will solve the problem, we recommend the repair. If solar doesn't make financial sense for a specific property, we say so. Most of our business comes from referrals, and that is only sustainable if the recommendations hold up. Sigma Solar & Roofing is licensed and insured in New Jersey, NJ HIC #13VH12599100, and a member of the Essex County Chamber of Commerce.
