Like many things, roofs require regular maintenance to stay in peak shape and continue to function. If neglected, the build-up of moss, dirt, twigs, leaves, and algae can cause many serious issues. This is why we suggest you regularly maintain your roof by having it professionally cleaned at least once a year!
Roofs are exposed to a great deal of moisture and debris that can cause all sorts of problems, especially here in the Pacific Northwest. Outside of debris from trees, excessive rain and pooling water provide perfect conditions for moss, algae, and other microorganisms to develop on your roof. These not only look unsightly but can also cause potential leaks, wood rot, and other potentially costly issues.
