At Mr. Bubble Wash we use the soft wash method rather than traditional pressure washing. Soft washing relies on a biodegradable cleaning solution and a low‑pressure spray (typically under 300 PSI) to gently remove dirt, algae, and moss from your roof. Our technicians apply the solution, allow it to dwell for about 15–20 minutes to break down organic growth, and then rinse it away using the same low pressure. Because we’re using chemical action rather than brute force, we’re able to kill algae and mildew at their roots and keep them from quickly coming back.
Why we don’t pressure wash roofs
High‑pressure water, typically 1,500–3,000 PSI, is great for concrete or metal surfaces, but it can harm most roofing materials. On asphalt shingles, high pressure can dislodge the protective granules, causing premature deterioration. Clay or concrete tiles can crack under excessive pressure, and water can be forced up under the roofing material. Industry experts advise against pressure washing roofs for these reasons. Soft washing avoids those risks and is gentle on shingles, tiles and other delicate surfaces.
By using soft washing and manufacturer‑approved cleaning solutions, we safely restore your roof’s appearance and help extend its lifespan. We also protect surrounding plants and property throughout the process.
