Moss On Roofs

When a roof is neglected, there are instances where moss will begin to grow on the shingles. In general, moss will grow in areas that are shaded and that have periodic exposure to moisture. While moss growing on a roof is considered to be a cosmetic issue, moss growth results in moisture retention and can cause the roof to age much faster. Additionally, damage could be caused to the shingles when the homeowner attempts to remove the growth. In order to extend the life of the roof, homeowners who are experiencing moss growth may wish to contact their local Ocean County roofing contractors for help.

If the shingles have been damaged to the point where they are cracking, worn out or fragile, a completely new roof will be needed. If the roof has not yet reached this point, there are ways that the roof can be cleaned without causing further damage. A power washer can be used, though the water pressure could cause the protective mineral granules to become loose and fall off. This will cause the roof to age much more quickly. A gentle cleaning using a soft brush may also remove the moss.

In some cases, a flexible leaf rake may be used to uproot the moss. As with the power washer, raking can cause damage if it is not done gently.

Additionally, this method often leaves quite a bit of debris on the roof, making it difficult to observe the integrity of the shingles. Once the moss is removed, the roof should be washed using a garden hose. If the debris is not removed, the gutters could become clogged.

Finally, there are chemicals available that could kill the moss. Due to potential environmental contamination and potential damage to the roof, this method of moss removal is not recommended unless there are no other options available. It should be noted that this method may not completely remove moss in areas that tend to retain water.

If moss growth is a big problem, a contractor may have methods of prevention. For example, if the roof needs to be replaced, they may have knowledge of moss resistant shingles or other roof products that prevent moss from growing. If the roof does not yet need to be replaced, the contractor may be able to install copper or other metal strips along the roof ridge. As water runs down the metal and onto the roof, the moss will be killed. Finally, trees blocking the sunlight can also be pruned back.

Question and answer from Ocean County roofing experts Fortified Roofing:

What are the conditions for moss growth on a roof?

For moss to grow on a roof, it needs three main elements: certain temperatures, shade and moisture. If a section of the roof is shaded and the temperature is between 32 degrees and 70 degrees Fahrenheit, it is likely that moss may grow. If the temperature rises above 70 degrees, the moss may become dormant but will not die.
