Why is it beneficial to clear debris from a BUR roof?

Removing debris from a Built-Up Roofing (BUR) system is particularly crucial to prevent water ponding and possible leaks. When leaves, dirt, or other materials accumulate on the roof surface, they can obstruct proper drainage. This blockage may lead to standing water, which increases the risk of leaks over time due to the prolonged exposure of roofing materials to water.

Water ponding can weaken the roofing material, making it more susceptible to damage from environmental conditions such as UV rays and temperature fluctuations. If standing water is left unaddressed, it might lead to structural issues within the roof and necessitate costly repairs or even a full replacement of the roofing system. Thus, regular maintenance that includes cleaning debris is essential for prolonging the lifespan of a BUR roof and ensuring its integrity against leaks.
