Cleanliness is key to prolonging the lifespan of your TPO membrane roof. However, the washing process itself can pose risks if not approached with care. In this blog, we’ll look at four precautions you must observe to ensure a safe and effective TPO membrane roof washing experience.
- Sweep Any Visible Debris Before Washing. Loose particles like twigs can be abrasive to the TPO membrane during washing, which compromises its integrity. Therefore, take the time to thoroughly sweep away any visible debris from the surface before commencing the cleaning process.
- Protect Any Points Where Water Might Seep Through. Pay close attention to areas on the roof, like low curbs and base flashings, where water could potentially seep through. Protecting these vulnerable spots with appropriate coverings will prevent water infiltration, which can cause water damage to the underlying roof structure.
- Wash with a Mild Cleaning Solution and Low-Pressure Water. Soft washing is the best TPO membrane roof washing method since it uses a mild, biodegradable solution to emulsify dirt and grime. Once the solution has displaced the dirt from the roof’s surface, you can easily rinse the residue with a low-pressure washer. Unlike other cleaning methods, soft washing won’t erode the membrane’s seams or protective layers.
- Don’t Leave Standing Water After Washing. Ensuring your TPO membrane roof is free of standing water after washing is essential. Leaving standing water behind can promote the growth of mold and cause damage. Such issues may contribute to the roof’s premature deterioration.
While following these precautions will significantly reduce the risks associated with TPO membrane roof washing, we recommend seeking the expertise of a company that specializes in soft washing roofs. With their extensive knowledge of soft washing equipment and techniques, they’re better positioned to ensure thorough cleaning while maintaining the integrity of your valuable roofing investment.
