Moss Growing On Shingles Of Roof

Once the spores get on the roof they gather in the spaces between shingles and grow into thick spongy moss.

Moss growing on a roof may or may not be considered attractive or quaint but there is no doubt that extensive moss on a roof can seriously damage the roof by growing under and raising or loosening. Over time moss can also work its way under shingles lifting them up. This lack of drainage not only helps the moss grow and thrive but also may damage your roof because it increases the risk of water getting under the shingles. It helps keep your roof wet by storing moisture and preventing proper drainage.

Hello wood rot and leaks. Since moss thrives in damp environments areas of the roof that get the least amount of direct sunlight like north facing sections or areas shaded by tree limbs make an ideal place for it to grow. Moss growth will also interfere with proper drainage of water off the roof as water needs to trickle through or around the moss instead of running straight down to the gutters. The seams between the shingles and the shingles edges also develop moss because they tend to be especially shaded.

Moss on a roof begins with a thin dusting of green that you may notice only from low angles. Moss and lichens are more than a cosmetic issue on many kinds of roofing materials asphalt shingles roll roofing wood shingle roofs wood shake roofs. You can apply the copper solution to new roofs to prevent any growth for a number of years. This moisture increases the weight of the roof which increases the risk of collapse decay leaks and water damage.

The resulting constant exposure to water can degrade shingles. Moss starts as a thin green layer on and between shingles but then it proceeds to lift those shingles up as it grows allowing water to seep underneath. Moss keeps the roof wet. Once under the shingles the moisture can reach the underlying structure.

Moss and green algae require dead organic matter for nutrients so you can prevent their growth by blowing off the shingles to remove junk from trees that tend to accumulate between the tabs.
