This is the step where most roofing contractors and cleaning contractors will agree that the most damage is done to the roof. The walking of the technician back and forth wielding a heavy high pressure washer dragging heavy hoses with steel quick connects and couplings across shingles and tiles.
As a Tampa homeowner you want as little walking upon the tiles as possible to reduce the risk of cracking the tiles. A roof cleaner using a pressure washer will be required to blast every square inch of the roof, requiring the technician to walk upon every tile. Also, the high pressure washing system uses force to blast the roof stains from the tiles. This can chip, fade and weaken the tiles and mortar integrity causing premature replacement.
Pressure washing only removes the visible portions of the algae and does not kill the spores that reinfect the tiles. Using the proper ratio’s of bleach with tsp ensures the algae is killed down to the root, including all of the spores that make more ugly black roof stains.

This causes the tiles to be pulled out of place and eventually the tile will crack or chip.
Surface cleaners or hydro-scrubbers are designed to be utilized with cleaning concrete. This tool resembles a floor buffer and has a spinning bar with high pressure tips angled under the broom.
