Waterproofing is the primary function of a roof coating, so selecting a product with proven leak-stopping capabilities is essential. Look for coatings with strong elongation, low permeability, and specialized formulations for ponding water if necessary. PONDING WATER FLAT ROOF COATING - AGPW5G is engineered for areas with standing water, offering guaranteed leak-free protection for 15 years. ROOF COATING FOR TAR & RUBBER ROOFS boasts the lowest moisture transmission rating for maximum waterproofing. Starting with a coating that has a low permeability rating allows the coating to still have superior leak prevention as it ages and the pores of the coating start to open up from continued expansion and contraction. Open or stretched-out pores are often the reason your roof leaks, even without any visible signs of where the leak is. So no matter how hard you try you can't see or find the leak. It's because the microscopic pores of your coating have stretched open just enough to let moisture pass through, usually during heavy downpours or wind-driven rains.
