Before you consider allowing a pressure washer to be used on your roof:

To brighten up/clean the roof

To remove algae / dirt that has built up on the roof

To protect Algae, fungus from human, animal airborne health hazards. Read below link by Doctor.  http://www.brightwaycleaning.com/uploads/roof_mold_health_issues.pdf

Why You Should NEVER ALLOW a Pressure Washer to be used on your roofing

Shingled roofs are pretty obvious. Cleaning them with a pressure washer will blow the granules off, in fact quite a large % of them!

Also, the most common roof tiles in Florida are made from concrete and have a sandy/granular finish on the exposed side of the tile, or a smooth finish and glazing.

Using a pressure washer may strip the surface of the tile and shorten it’s life expectancy.

The roofing manufacturers specify a chemical, self cleaning method, with instant results.

That's how I clean roofs.

It's gentle, the cleaning agents are bio-degradable { Green }

It lasts more than twice as long as a power washing job does.

Unlike the pressure washing method, the manufacturer method kills off all living algae spores, including the roots.

Power washing with a gun or a { circular } "spinner" "Rotary" surface cleaning machine, does not kill off the living algae.

It just blows it up under the tiles and shingles and may even blow it into the underlayment of your roof!

Also, that pressure will blow algae spores all over everything within 10' of your roofs edge-spreading the algae infestation to your house trim, walls, sidewalk, driveway and pool / lanai areas!

Pressure washers work with thousands of pounds of pressure. Soft Washing, as I do, uses a 60 psi pump, which is strictly for delivering the manufacturer specified cleaning agents, to the roofs surface.

Once applied, it often comes 100% clean and has no living algae spores left to continue growing.
