Attached below are 2 technical bulletins from the Asphalt Roofing Manufacturers Association. You will need adobe reader to view the files. The ARMA Technical Bulletin gives details about the approved cleaning solutions we will use to clean your Kissimmee Tile and Shingle roofs. The second bulletin talks about the disadvantages of "Roof Coatings" that many companies promote. Not only are roof coatings expensive (in some cases 6-10x the cost of a cleaning), your shingle manufacturer does not recommend the application of a roof coating system. This could void your shingle warranty. |
