Moss Removal & Treatment

A moss-covered roof, left untreated, is unsightly. What’s more, it compromises the roof’s integrity, deteriorates the shingles, shortens the lifespan of the roof, can create leaks and most importantly can cause you to lose or have an increase in your homeowners insurance. Here in the PNW we are not shy to rain. Moss commonly thrives in environments that are cool, damp, shaded and usually seen on north facing roofs. Moss is a non-vascular plant that absorbs water through its leaves instead of roots. Its seeds, called spores, are tiny one-celled reproductive units that become air-borne and make their way onto roofs via wind, birds, squirrels, and other small animals. 

There are several different ways to clean roofs. We lightly brush the larger clumps of moss off the roof, then apply a wet or dry treatment to kill the remaining stubborn moss. Moss removal needs to be done once as long as preventative treatment is applied annually. To avoid the higher cost associated with removal, we recommend applying moss treatment once per year or immediately upon noticing any new moss growth. If you already have moss growing on your roof give us a call and one of our technicians can get your roof back to the condition it should be in.
