Why is Moss on The Roof Bad?

Although the reasons are some what debated in the roof cleaning industry there is definitely one common conclusion and it is that moss is not good for roofs. We have posted a few of the reasons commonly accepted within the industry for why moss is bad for shingle asphalt roofs.

As the moss thickens and grows on an asphalt shingle roof it can raise the shingles up (much like a jack under a car). When the shingles get risen it allows water to go under the shingles causing the decking to rot and causing the roof to leak. The raised shingles also pose problems when heavy winds are present because they will catch the wind like a sail and this can cause shingles to be torn/blown off the roof.
A moss buildup on the roof causes more debris to get trapped on the roof. This debris promotes water buildup which makes the roof at risk of much more rotting and leaking.
Moss can actually damage the asphalt shingle components leaving it to break down faster.
