Roof cleaning is the process to remove dirt, algae[1] and moss from roofs.[2]Roof cleaning can extend the duration of a roof's ability to function.[2] Algae and other types of build-up often form on parts of roofs that are shaded, and can reduce a roof's life expectancy.[2] The presence of soot, dirt, or biomass can affect how much sunlight is absorbed by a roof and thus the amount of heat a building absorbs.[3] Cleaning may be accomplished with a bleachor vinegar solution, various cleaning products or commercial cleaning services. The addition of zinc strips near the roof's peak may reduce the regrowth of algae and moss.

Cleaning apparatus

Roof cleaning devices may use high-pressure water spray and revolving brushes, and some may have extensions to enable their use from the ground.[4] Roof cleaning devices exist that may minimize the spread of airborne radioactive materials (in contaminated areas) and other harmful materials, such as asbestos.[4] Specialized robots have been designed to facilitate cleaning roofs.[5]

For doctors trying to reach their patients online, using Google+ can provide surprising marketing benefits that help them be more “findable” on the web.
