Roof Washing (Soft Wash & Clay Tile) in Harlingen, TX

Spanish clay tile roofs are a signature architectural feature across Harlingen, McAllen, Brownsville, and the Rio Grande Valley. However, porous clay tiles under the blistering South Texas sun act as magnets for airborne mold, mildew, and black algae (Gloeocapsa magma). Standard pressure washing is catastrophic for clay tile roofs — it shatters brittle tiles, strips factory glaze, and causes massive interior leak hazards. Tough clay tile requires higher-strength, targeted chemical treatment combined with delicate soft wash application. Our specialized blend safely dissolves years of baked-on black discoloration without scrubbing or abrasive pressure.

Walking on clay tile roofs is the number one cause of broken, dislodged, or leaking tiles. Extreme Wash Pros uses high-output, long-distance soft wash equipment capable of shooting treated streams from ladders and gutter perimeters, minimizing foot traffic on your roof structure.

A roof blackened by algae absorbs excessive solar heat, forcing your air conditioning system to work harder during scorching South Texas summers. Restoring your roof's bright, reflective color reduces heat transfer into your attic, extending the life of your underlayment and saving you money on electricity.
