Roofing

We’ve been replacing roofs across Nassau County and Suffolk County. Zajac Home Improvement is fully licensed and insured to replace the roof on your home. Each and every roofing job is eligible for our financing promotion, and we provide free estimates. We install roofing materials from the following companies: CertainTeed, GAF, IKO, Owens Corning, and TAMKO.

Each and every customer receives a free estimate and a satellite print out confirming the exact measurements of the size of their home. No matter the brand of material you select, CertainTeed, GAF, IKO, Owens Corning, or TAMKO, we follow the manufacturer’s installation specifications in order to qualify for your manufacturer warranty. We offer a lifetime labor warranty on every job in addition to the manufacturer’s warranty.
