Moss will usually grow under moist conditions and in an area of your roof that doesn’t get a lot of sunlight. This can happen especially in areas where trees shade the roof. However, the subject of whether moss on a roof should be removed or not is a much debated subject, and a deciding factor is whether the moss is actually creating a problem. In our last post we discussed the damage that improper and reckless cleaning of a roof can cause, but how do you know if the moss itself is actually causing an issue?

To answer this, think about where the moss is located. Could it be blocking drainage points like gutters and downspouts? Is it growing in and around the gutters as well as on the roof? In cases like this, the moss could be preventing your gutters from working properly which could lead to damage to your roof. Structural problems could also arise as a result.

Another thing to think about is the type of roof shingles and the structure of the roof. If roof shingles are made are stone or clay, its probable that any green growth is not causing any damage at all. On the other hand, something you would want to check out would be the possibility that moisture from the moss is rotting either the shingles or the roof structure. Inspecting to see whether moss is causing damage to your roof or not, probably would benefit from a closer look from a professional. Please don’t hesitate to contact us for more information.
