Is roof cleaning necessary?

One reason to clean the roof is to extend the life of shingles or other roofing material. While algae isn't harmful to asphalt shingles, moss is, according to ARMA. Moss can cause the edges of shingles to bend upwards, making them more likely to come off the roof when it's windy. Tiled roofs are durable, protective and beautiful, but are prone to algae growth.

That's right, the black stripes you see on your roof are made up of algae. Cleaning roofs removes these algae along with any other debris, such as leaves, dirt and road dust.

It's generally a good idea to have professionals clean the roof once a year. This is usually sufficient so that, if problems occur, they can be detected early on. If you have a roof that is in good shape or was recently installed, you may only need to clean it once every two years or so.

Mold, algae and bacteria like to grow wood and asphalt roof shingles as soon as possible.

A gentle wash occurs when a biodegradable cleaning solution is sprayed onto the ceiling, which penetrates all the cracks and the underside of the shingles. You may love to experience the four seasons of the year in the Pacific Northwest, but your roof doesn't. How often you should clean it really depends on several factors that affect its condition. The exceptions are ceilings made with ceramic or concrete tiles, which can be strong enough to withstand the force of pressure washing.

A new roof is a major investment, so of course you don't want to have to replace your roof sooner than necessary. As a general rule, it's best to avoid pressure washers or high-pressure washing of most types of ceilings. There are many other reasons why you may need to clean your roof more often or do additional roof maintenance than normal. The solutions will begin to break down lichens, moss and algae, as well as stains and discolorations on the ceiling.
