Roof Cleaning

Roof cleaning is the process of removing algae, mold, mildew, lichen and moss from roofs.

What is the black stuff on my roof? Answer. Those black streaks on your roof shingles are most likely an algae called gloeocapsa magma, or as it is more commonly referred to, a blue-green or black algae. Algae is a solid deposit of spores and dirt, another form of mold. Do NOT pressure wash your roof; one wrong angle and you can damage the shingles. Roof cleaning using a soft wash technique can eliminate this.

You can clearly see the gloescapsa magma streaking on this roof before treatment.

The results speak for themselves. A soft wash treatment will rid the shingles of the mold and prolong the life of the shingles. We use a biodegradable solution that effectively and safely eliminates all mold and algae on the shingles. Precautions shall be made in order to protect any vegetation prior to application. This can be a very confusing service for some so please contact us for further information as we will be more than happy to help out.

Should I remove mold from roof?

A small amount of moss is relatively harmless, but left unattended, it can grow and eventually damage your asphalt shingles. Moss should be removed. Algae actually fosters the growth of mold, which can lead to very serious issues. Algae, too, should be removed quickly and efficiently. Roof cleaning isn’t as popular here in Minnesota like it is in the southern states, But does that mean you shouldn’t do it? We don’t think so. The same mold appears here just as it does in the southern climates. Most noticeable will be any surfaces that face north and west as this area receives less sun light overall.
