What are the best chemicals to use when roof cleaning? Typically, a 3-4% sodium hypochlorite solution is used in conjunction with TSP or Tri-Sodium-Phosphate.

This is the go to source for roof cleaners of FL and beyond due to the availability and cleaning power.  The base of every cleaning solution is always SH. In fact in my experience cleaning thousands of roofs you absolutely do not need to add anything other than water to the bleach.

But, once you start cleaning a lot of roofs you get the feel for what you would want the solution to do.

When SH does not have a emulsifying agent mixed with it the solution runs and is 'wet'.  Kinda of like when a painter thins his paint for certain applications, it makes the paint thinner or 'faster'.  Well when SH is used alone it is fast and tough to keep up with the run-off and over-spray when roof cleaning Tampa FL hot sun.

The addition of TSP not only gives the SH more dwell time due to the emulsification, it dramatically contributes to the overall cleaning power of the solution.  This justifies the cost of adding the ingredient.  You use less SH and the client gets a better cleaning. 

Here is a picture of a business park complex that we
provide semi-annual exterior and roof cleaning services
for. You can see the solution was sprayed from one
spot and is highly emulsified, therefore the cleaner
does not run off of the tiles.
