 We NEVER Pressure Wash any tile roof, no matter what. 

The black discoloration you see on your tile roof is not dirt. Actually, there is very little dirt and atmospheric pollutants on your roof at all. The discoloration you are seeing is a plant that has taken root, and is growing on your roof tiles. Pressure Washing does not kill this plant, it simply blasts it, and it's still living spores everywhere, where it will quickly grow right back!

It is not unusual for a person who was foolish enough to pressure clean their tile roof, to have to clean much of the home later on. The plant that was removed by the pressure cleaning and spread everywhere, has now started growing on the home, sidewalks, and driveway!

Here are some other dangers you face, if you elect to have your tile roof cleaning done with high pressure washing.

Pressure Cleaning a flat cement tile, ceramic tile, or barrel tile roof, will often break or damage your tiles. 
Pressure washing a tile roof requires walking all over it. 
If all that walking around doesn't bust up your roof tiles, the high pressure certainly can. 

Just try and get an inexpensive Tampa Roofing Contractor to replace roof tile, and/or do leak repair to the underlying roofing membrane ! 

Try this test, stand on a ladder with a pressure washing wand in hand and pull the trigger. 
The high pressure can knock you right off the ladder! 
Imagine what that harmful pressure washing is doing to your tiles, and/or your roof membrane ? 

The surface cleaning devices used by some Tampa Pressure Washing company's aren't any better. 
They were designed for pressure cleaning parking lots and driveways. 
They are just a pressure washing contraption with their own set of problems. 
They are designed to "ride on air" on a flat surface. 
A barrel tile roof is not a flat surface, and as the surface cleaner passes over the tiles, it can easily smack into the edges of them like a sledgehammer, causing breakage. 

We have been cleaning tile roofs in the Tampa Florida area w/o using any pressure for nearly 20 years.
