ROOF WASHING

What is the importance of having a clean roof?  
 
Roof cleaning removes algae, mold, mildew, lichen, and moss from roofs. Moss and algae can make the edges of the shingles curl upward, making them more likely to blow off the roof during windy weather.
Cleaning can extend the duration of a roof's ability to function. By maintaining an adequately cleaned roof, you are prolonging the life of your roof.
