Read more about Roof Cleaning...
Roof cleaning is the process of removing algae, which can be mold, mildew, lichen and moss from roofs. Cleaning can extend the duration of a roof’s ability to function. Algae and other types of build-up often form on the north and west parts of roofs that are shaded or receive less sun, and can reduce a roof’s life expectancy. 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
Why Do It?
Only a really serious build-up of dirt, moss on roof tiles and other stuff is likely to cause you major problems with your roof. The life-span of the tiles may be affected eventually, but for most people cleaning their roof is a purely aesthetic decision.
The difference between a clean roof and one that hasn’t been cleaned can be night and day. It will probably end up looking brand new again after this work, which is a fantastic thing to see after years of it getting progressively dirtier and older-looking.
If you apply a fungicide/moss killer after the moss has been scraped off, it will soak into the tile and more importantly into the overlaps of the tiles and kill off any tiny moss spores. It will also kill off lichen and other organic growth on the tiles. This roof cleaning process can take some time after the excess moss is initially removed but there is no damage to the surface of the tile.
The application of roof cleaning chemicals will also prevent the moss from growing back for several years. As a bonus, this chemical will also kill lichen, so those black marks on the tiles will fade away a few weeks after the treatment.
