With falling leaves, nuts, and branches, one of the first things to address is your roof’s drainage: internal drains, scuppers, and gutters.
Debris will be washed to these areas and clogging can result. As rainwater backups, it can overrun gutters, curbs, and mechanical equipment causing leaks.
With flat roofs, standing water not only increases weight strain on your roof, but silt build-up also creates dark spots on the surface of the roof once the water evaporates.
On white TPO membrane roofs, these dark areas attract the sun’s rays and can raise the roof’s temperature to as high as 160 degrees. Over time, overheating of the TPO membrane will cause the fibers in the membrane to break down the material’s fibers. If not cleaned, this can eventually destroy the membrane completely.
