A TPO roof is known for its durability and energy-efficiency. Routine cleaning is important to maintain its white surface and reflectivity.
In today’s post, your local roofing contractor, Affordable Roofing Systems, discusses how to properly clean your TPO roof.
The Importance of TPO Roof Maintenance
Debris and dirt can accumulate in the low-slope roof and lead to algae and plant growth. The debris can also be food sources for birds and pests. Chemical contaminants can also settle in the roof and cause damage to the membrane and compromise its life span.
Since the membrane of the roofing system can be slippery, all fall safety requirements must be followed. Avoid walking in areas where the cleaning solution has not been washed out.
Test a small spot in the area where the run-off meets the facade to make sure that the cleaning solution doesn’t harm the exterior. Make space for the run-off cleaning solution to prevent damaging plants and contaminating groundwater. Local and federal requirements for water runoff should be consistently followed.
TPO Cleaning Tips
Several factors affect how often you should clean your TPO roof like rainfall frequency, dirt and dust accumulation, and roof slope and drainage features. Keep in mind that some roofs may require frequent cleaning.
When cleaning your TPO roof, the low curbs or areas where water could enter should be protected. Keep away plants, shrubs, and exterior faced from cleaning solution run-offs. A low-pressure washer should be used to clean and rinse the top layer of debris.
Prevent damage in the membrane by using a soft-bristled brush with a long handle or a floor broom. A mild household detergent and water should be used in cleaning the membrane’s surface. This should be followed by completely rinsing the roof using a low-pressure power washer.
After cleaning, the roof should be inspected for damage and any incidental damage should be repaired according to GAF’s guidelines.
