In our opinion, any roof surface brushing or raking should be done with great care to minimize damage to the shingles themselves. If there is any doubt about the condition of the shingles underneath the moss, work gently by hand on a small area first to see the condition of the shingles below.

If the roof shingles are fragile, brittle, cracking, curled, the risk of serious damage to the roof during moss removal is much more likely. The roof may look cleaner, but its remaining life may be reduced by aggressive cleaning.

Other recommendations include hand-scraping moss off your roof, yet hand-scraping is only a preliminary method in the many steps involved in removing moss. Similar to the pressure washer, hand-scraping will only remove the visible layer of moss and fails to get rid of spores and clusters that can spread and stimulate regrowth.

Bleach can also kill moss, but if not used properly, it can lead to discoloration and ruin vegetation on and around your house. Its important to be cautious when using bleach, especially if youre not familiar with the solution as it can irritate the eyes and/or burn your skin. Its often best to leave the chemicals to moss removal professionals like Clean Break Home Services, who use a 12.5% industrial standard bleach solution and know-how to create a safe mixture that offers maximum effectiveness.

While moss may appear to be a seemingly unthreatening plant, moss truly can cause severe damage to a home. Like most plants, moss grows roots, and as the moss on your roof grows so does its root system, which can burrow under your homes shingles, lifting them and damaging your roof.
