Concrete Roof Coating
Concrete is porous and susceptible to shrinkage cracks and ponds. The permeability of concrete lets moisture penetrate and stay in the slab. Concrete is also a heat battery. It absorbs the sun’s heat and takes as much as 4 hours at night to fully dissipate.
Your modbit roof may be APP or SBS modified. For roof coating applications, it really does not matter. Smooth modbit roofs are easier to coat and repair. Granulated modbit will just require more coating. No matter what type of modified bitumen roof you have, roof coatings are a very cost effective way of extending the life of your roof.
What about ponding water?
Large, deep ponding water should be corrected by installing additional area drains or raising the depressed area to create positive slope whenever possible.
Water weighs about 8.3lbs/gallon and a large pond will continue to add stress on the structure and create an unsafe condition for the occupants of the building.
