Why is it bad to have moss growing on your roof?
Written By: Matt Holmes ~ 9/14/2020

Moss and algae tend to grow in damp, shaded areas and can cause damage to your roof both directly and indirectly. If you allow large patches moss to grow on your roof, these patches hold water against the surface of the roof, which can cause the roofing materials to rot and deteriorate.  Therefore, having to replace your roofing more than needed. In addition, the water trapped in the moss pools in gaps between your roofs shingles, and as the water freezes and thaws it can pull the shingles apart, causing even more damage. The growth of moss on the shingles and the constant water underneath will also damage the shingles causing them to curl up on the ends. Over time if left untreated, the moisture will start to creep into the wood causing water damage and leaks in the roof.  We suggest having moss removed on a regular basis so that way none of these situations happen to you!  You can call us for a free estimate and our suggestions on a schedule to keep moss growth under control.
