Follow on Google News | Recent Rain In Atlanta and North Georgia Is Turning Roofs To Many Homes GreenA large increase in rainfall over the last several months has left many Georgia homeowners worried about their roofs turning green!
By: info@RoofContractorsAtlanta.com After some consoling, Crisp explains that the green roof effect is simply the result of the unusual amount of rain that Georgia has experienced in the last year and the resulting growth of algae. Algae growth causes a dark discoloration on roofs. The algae is usually brown to black in color which results in a streaked, dirty looking rooftop. It can be mistaken for soot, dirt or tree droppings, which typically produce only localized discoloration. It's caused by the growth of air-borne algae which deposits on your roof. The good news is that algae growth does not affect the service life of your roofing material. It occurs most often in warm, humid climates such as the Southeast (where algae-resistant shingles are available). Discoloration of roofs caused by fungus or algae is difficult to remove, but may be lightened by spraying a diluted solution of chlorine bleach, trisodium phosphate, and water onto the roof. Solutions range from one cup TSP, one gallon bleach and four gallons of water, to one cup TSP and 2.5 gallons each of bleach and water. This solution can then be rinsed from the roof in 10 to 15 minutes. Do not scrub. Scrubbing will loosen and remove granules. After spraying be sure to thoroughly flush the roof and the greenery around the home (grass, bushes and shrubs) with water. The effectiveness of this type of cleaning may only be temporary, and the discoloration may recur. High pressure washing is not recommended due to the possibility of removing granules, thereby shortening the life of the Roofing System. For a more permanent solution, RainTec roofing recommends re-roofing with Owens Corning Algae-Resistant Shingles. They are specifically designed to inhibit most algae growth for extended periods of time and are backed by the strongest product and algae resistance warranties available to homeowners. When asked if homeowners could install a new roof over their existing roof. Crisp explains, "Maybe - it depends on the structure of the house. Roofing over an existing roof is possible if the additional weight can be handled by the house support.
