Here is the last of the 3 part video of a shingle roof cleaning here in Tallahassee. We never use a pressure washer on asphalt shingles as it is highly discouraged by ARMA (Asphalt Roofing Manufactures Association). ARMA is the largest manufacturer of asphalt shingles in North America and we use the only methed of cleaning roof stains, caused by algae, recommended by ARMA to date. Feel free to give us a call for a free estimate!

Also, "A picture is woth a thousand words" blooper towards the end of the video should provide some comic relief for the forum members! (especially Pat)
