A rubberized roofing membrane can protect and maintain your flat roofs from leaking for many years. If it’s properly maintained, your rubberized roof can even last 50 to 60 years! Firstly, you have to know that flat roofs are not exactly flat, but they offer slopes at such a low angle that water doesn’t flood your roof. As a result, the water gathers around the scupper, and hence the scuppers and the low side of the roof wear out ten times faster than the high side of the roof. 95% of all leaks on flat roofs is caused by scuppers.
The first step in reviving damaged roofing is to reinforce all the cracks and damages with the polyester roofing membrane to prevent them from cracking again. Also, check the parapet walls and patch the cracks, if any, with rubber cement. Secondly, installing a rubber coating membrane, an excellent sealant that prevents water from entering your roofing. Where the plastic dome goes under the aluminum frame is where skylights leak and must be siliconed each time a roof is coated. Finally, once the water barrier is fixed, an elastomeric coating is done on the roofing. The elastomeric coating is not only a water sealant but also an excellent UV block. All drip edges must be re-nailed each time a roof is coated.
