Here is a big South Tampa Roof (9500 sq ft) we cleaned recently.  This home is right on Bayshore Blvd, across from Tampa Bay!

The before and after the roof cleaning pics are not very good (my memory card was full). 

Because this roof was a light colored one, we used some TSP in our mix for maximum cleaning. Our monster sized air compressor and roof cleaning pumps (we had 2 trucks on this job) made quick work of this job for the well known Tampa Attorney who was doing the renovations.

Bayshore Blvd here in Tampa Florida is one of the most expensive areas to live. 

Many homes on Bayshore would be called mansions, and have lots of roof surface on them. Many of these roofs need cleaning, and do not have gutters, with tons of old, very expensive landscaping. 

Most roof cleaning work in this historic area of Tampa is done by reputation, and word of mouth.
