Asphalt shingles are among the most popular roofing materials in this country, but why is that? One obvious answer is that the price is right, and that is definitely a large part of it. Asphalt shingles have the lowest price on the market being available for as little as $70 per square, but that is not the only thing that is appealing about this roofing material. Asphalt shingle roofing is one of the easier materials to install, and it can even be installed on top of an existing shingle roof. The lifespan of an asphalt shingle roof is not the longest, but with care it can be extended. There are some issues that are more common with asphalt shingles than other types of roofing, and the textured surface of the roofing has a lot to do with that. It allows moss and mold to get a foothold if not prevented.
Because of this, it is important to keep the roof clear of leaves or branches that will hold water and encourage growth. If you do notice that something is starting to grow, a mixture of 50% bleach and 50% water can be used to clean the roof.
