Roof Moss Removal and Treatment
Serving Vancouver WA and Portland OR
Although green roofs are becoming more popular with environmentally conscious companies, they are created following a specific plan and with appropriate support. A commercial roof growing its own greenery needs attention from a reputable roofing contractor as soon as possible. Roof moss removal and treatment will protect the structure from potentially dangerous or expensive repairs in the future.
How to Identify Roof Moss Problems
The number one way of identifying moss is through a simple visual inspection. Get up on the roof if it is safe or hire a reputable roofing contractor to perform an inspection. Moss forms green clumps or cushions in spots with high moisture. Seams and cracks sometimes collect moss spores more easily. Growth retains water in these spots and can contribute to increased chance of rotting or mold formation.
Lichens and small plants can also begin to grow on commercial roofs. Lichen, which is very flat and dryer than moss, poses less of a threat to the materials than moss. Plants such as baby trees and weeds growing on a roof can definitely cause problems and indicate a need for maintenance.

The Roof Moss Removal and Treatment System
As long as the roof material is sturdy enough, the roofing contractor will scrub or power spray the moss and lichen off of the shingles or sheets. Specially built rakes are most frequently used. All the moss is discarded appropriately so it does not regrow on the roof or elsewhere.
After the roof moss removal process is complete, regrowth is halted with an application of an earth-friendly yet highly effective solution. This stops moss spores from regenerating so any tiny bits left on the roof will not grow and cause problems all over again.
On commercial buildings with synthetic or metal roofs, moss is less of a problem than on wood or organic or asphalt shingles. For one reason, there is less for the tiny moss spores to root onto. Still, whenever plants are nearby and the moisture conditions are correct, moss growth can become an ever-increasing problem. Dealing with moss removal before it gets out of hand is the best bet for a roof’s long life.
