That’s not dirt! It is roof-eating algae.  It is feeding on the limestone that provides strength to your shingles.  This algae causes about 80% of roofs to be replaced early.  Not to mention, these unsightly roof stains diminish the value and beauty of your home.
A dirty roof may prevent you from selling your home.  It can raise doubts with potential home buyers, real-estate agents and home inspectors.  Cleaning your roof before you list your home could save you thousands of dollars!  Even an attractive and well cared for property, cannot conceal this eyesore.
Roof cleaning is fast and affordable with dramatic results.  There are very few home improvement projects that can offer dramatic benefits quickly and affordably.  When done properly, the results are amazing!
