Cement Tile Roof Cleaning Done Right – Beyond the Surface in Vancouver, WA

At Wow Wash 360, we recently tackled a cement tile roof cleaning project in Vancouver, WA, that highlights exactly why not all roof cleaning is created equal. While many companies stop at a basic soft wash of the surface, we go much deeper—literally. Cement tile roofs are more than just tiles on top; they have layered water channels and felt underlayment designed to protect your home. If debris builds up in the valleys or water channels under the tiles, it can trap moisture, leading to soaked felt, premature deterioration, leaks, and even structural damage.

For this project, our team safely removed tiles in the valley sections of the roof to access the hidden channels beneath. We thoroughly cleaned out years of compacted debris, organic buildup, and blocked drainage paths—something that can’t be fixed with surface washing alone. Once the hidden channels were cleared and flushed, we carefully reset the tiles to ensure everything was sealed and secure. We then soft washed the surface of the roof with a biodegradable solution to kill moss, algae, and grime without damaging the tile or underlayment. The result? A fully restored cement tile roof that not only looks great but performs as it should, with proper water flow and long-term protection.

If you’re a homeowner in Vancouver with a cement tile roof, don’t settle for a surface-level clean. Trust Wow Wash 360 for deep, structural-safe tile roof cleaning that protects the integrity of your entire roofing system. We do it the right way—the only way it should be done.
