water ponding


I have taken on a roof repair that involves getting rid of water ponding . I have found a Henry product that is like a self leveler . Has anyone used a self leveling product to get rid of ponding ?

Yeah, its called a sumped roof drain. Put a brick in what you think is the deepest part of the pond. Move it to the remaining wet area as the water evaporates. Put your roof drain there. SUmp it and use tapered edge strip to break down into the drain. Mount the drain's sump receiver on wood blocking sistered to the joists. I only use cast iron drains, usually Zurn Z-100 with sump receiver and CI drain, but there are options. Do not use less than 3 inch drain and pipe. No-Hub, Fernco under drain. You have to flash the drain per the roof type which you have not mentioned. You can use a type A (Side Outlet) if joist height is an issue. DO not screw PVC into a Cast Drain, you need a galvy nipple, then a fernco. Plastic threaded adapter into CI will crack, as CI expands and contracts much faster than Plastic.
