The majority of home owners never consider roof cleaning as part of their home maintenance upkeep. Home owner insurance policies are being canceled nationwide when insurance representatives notice moss on roofs. The moss is alive and eating its way thru the roofing material, causing water and ice backups that can lead leaks and costly repairs.

Once the moss spore has landed an attached itself to a roof it spreads like dandelions. A roof has food, limestone in asphalt shingles and wood particles in cedar roofs that moss seem to love. Moss usually can only be found under the shade of a tree or on the north side of the roof because direct sunlight will not allow the moss to grow, so given the right conditions, moss will spread and cause serious structural damage to any roof.

To most home owners to idea of climbing up on the roof to clean the moss off seems quite unnerving to say the least, which is probably the reason most people let it go so long that replacement is their only choice but with the right roof cleaning product and few common tools it can be easily accomplished without even stepping foot onto the roof.

Power washing or brushing moss off of your roof without pre-treating the roof with an effective moss cleaner will only result in topical removal, meaning that the roots will be left behind, still feeding and will soon bloom again.

Caution should be taken when using bleach to remove roof moss or for any reason on a roof. Bleach relentlessly dries the surface that it comes in contact with, usually resulting in stains; the stains are because the surface has been damaged. The damage bleach can cause on a roof can be in the form of discoloration and excessive drying that will result in cracking of the roof material. Bleach is something that I would recommend avoiding when it comes to roof cleaning.

An option if you want your roof cleaned completely that day and don’t mind spending $600-1,000 dollars is to hire a roof cleaning company, they are professionals and can safely remove the moss.

A second option that is very successful is to do it yourself, the right moss removing chemicals can just be sprayed on the roof moss, causing it to turn brown and dry up. Then with Mother Nature’s help, the wind and the rain will rinse the dry moss from the roof. The only downfall, if you can call it one is that it takes about 90 days to see the final results but you are saving hundreds of dollars and getting basically the same results.
