Roof coating works by creating a seamless, self-adhered barrier over your current roof surface. Unlike a full tear-off, we clean, repair, and then apply a thick elastomeric coating that flexes with temperature swings—from the freezing ice dams of January to the 95-degree July afternoons near Davidson Mill Pond Park.
When you call South Brunswick Roofing, we first inspect your roof for rot, decay, or sagging decking. If the structure is sound, we can recover with a coating instead of replacing. We use ring-shank nails to secure any loose flashing, then apply the coating in staggered courses, starting with a starter course at the eaves. This method seals exposed fasteners and stops water from wicking into the substrate.
Roof coating costs between $3.50 and $7.00 per square foot, depending on the product and the condition of your roof. For a typical 1,800-square-foot home in Kendall Park, that's roughly $6,300 to $12,600—about half the price of a full replacement. Most coatings come with a 10- to 20-year warranty, and we back our work with a 5-year workmanship guarantee.
We've coated roofs on 1960s ranches in Monmouth Junction and newer builds in Dayton. One job in Franklin Park had a leaking valley that had been patched three times. We stripped the old sealant, primed the metal, and applied a self-adhered membrane—no more seepage, even during the heavy rains that roll off the Delaware and Raritan Canal State Park.
Roof coating is not the right fix for every roof. If shingles are curling, buckling, or losing granules at the end of their life, a coating won't stop the erosion. In those cases, we'll tell you straight—you need a replacement. But if your roof has 5 to 10 years left, a coating can add a decade of protection for a fraction of the cost.
