Ponding water repair is what we do when water sits on a flat roof long after the rain stops. The usual industry test is 48 hours. If water is still standing two days after a storm on your building in Stockport, OH, that area is taking a beating.
Standing water adds weight, feeds algae, attracts debris and works into any small defect in the membrane. It also shortens the life of most coatings, though silicone handles it better than acrylic.
The fix depends on the cause. Sometimes a drain or scupper is clogged or set too high. Sometimes the deck has sagged or insulation has crushed. We might clear and reset drains, add crickets and tapered insulation, fill low spots with a leveling compound, or build slope with spray foam.
We look at the whole drainage path, from the high point of the roof to the downspout, before recommending anything. Ponding water repair in Stockport, OH is often done right before a silicone roof coating so the new coating starts life on a roof that drains. Call (833) 441-4944 and we will come map the low spots.
