A building owner invests a great deal into a low-slope roof, but the job doesn’t end after installation. It’s important. The post How to Clean a TPO or PVC Roof appeared first on GAF Blog. A building owner invests a great deal into a low-slope roof, but the job doesn’t end after installation.
Keeping the surface white so it can provide maximum reflectivity and its associated energy conservation benefits Preventing the accumulation of dirt and debris, which can act as a nutrient source for algae and other plant growth Preventing the accumulation of food sources for birds and other pests Preventing the accumulation of chemical contaminants on the roof surface that may harm the membrane and reduce its performance life
Because of safety concerns and potential for roof membrane damage, GAF recommends you take these precautions:
First, only trained professionals should be allowed on the roof to avoid any damage to the integrity of the roofing system. Fall safety requirements must be followed—a wet, single-ply membrane is slippery. Use caution and follow all fall safety requirements. Avoid walking on surfaces where the cleaning solution has not been rinsed away. Where the run-off may come in contact with exterior facades, test a small area to make sure there are no deleterious effects to the façade from the cleaning solution. Be sure to make accommodations for the run-off cleaning solution to avoid damage to plants and contamination of ground water. Always comply with all local, state, and federal requirements for water run-off.
So, how often should a low-slope roof be cleaned? It depends on several factors such as the severity of environmental contaminants, the frequency of rainfall, the propensity for dirt and dust accumulation, and the roof slope and drainage characteristics.
