Ponding water roof solutions in Richmond Hill, Queens are a specialty of Queens Flat Roof Coating, in a neighborhood of aging early-1900s buildings with slow-draining flat roofs. Standing water is the fastest way to destroy a low-slope roof, and the old built-up roofs here hold plenty of it. We seal the surface with silicone built to withstand ponding and improve drainage where we can, all without a tear-off. Richmond Hill owners call us when water sits on the roof for days and the leaks have started.
Richmond Hill is a historic neighborhood of early-1900s wood-frame and attached homes, including grand Victorian houses near Forest Park in central-southern Queens, alongside older commercial buildings on its avenues. This aging stock carries flat and low-slope roofs of built-up asphalt and modified bitumen that have settled and sagged over the decades, so water ponds in the low areas. That widespread ponding on old, slow-draining roofs makes it a common problem here.
Standing water finds every weak seam and slowly works its way through, while its weight and constant saturation break down the membrane faster than anything else. Old built-up roofs that have settled over the years pond in the low spots, and that is where they fail. Solving the ponding is the key to making the roof last.
Silicone coating is the one system made to sit under ponding water indefinitely without breaking down. We clean and prep the roof, reinforce the seams and penetrations, and build the silicone up over the low areas into a seamless membrane. Where other coatings would fail under standing water, silicone holds its seal for years.
Coating handles the water that cannot drain, but easing the ponding helps even more. We clear and reinforce the drains and scuppers and, where practical, add tapered buildup to move water toward them. Better drainage plus a silicone coat gives the roof its best shot at a long, dry life.
