Roof Cleaning 101: Prevent Algae, Moss & Lichen Growth

Algae, moss and lichen spores blow about on the wind. When you consider the wind storms we get here, those spores can come in great numbers from far away! So it’s only a matter of time before they find your roof and tuck in to quickly grow, spread, and start causing damage. Demossing with regular roof cleaning becomes a must to get rid of them.

But first, what damage do these organic growths cause?

Algae

Algae causes those ugly black streaks and stains often seen on roofs. This alone brings down curb appeal and makes the house look uncared for. Algae also holds moisture which damages roofing material over time–even shingles.

Moss

Moss traps moisture and damages shingles as well. Left untreated over the winter, the water in moss freezes and expands. This lifts the edges of shingles and leaves your roof susceptible to water ingression (leaks), particularly when wind blows water underneath them. 

Lichen

Lichen (and some algae strains) eat away the top layer of shingles, causing early degradation of your roof. It drastically reduces the lifespan of your roof. We all know, a new roof is not cheap!

There are ways to deal with these issues. You could install zinc or copper strips on your roof to kill these substances. Most people, however, are not at ease doing this. It’s dangerous and takes special skills and equipment.
