Moss is a flowerless green plant that grows without a stem system. Having no roots allows moss to grow where other plants cannot. Moss can grow naturally on almost any surface including roofs.
Roofs that are shaded from the sun, especially cool damp areas are perfect breeding grounds for moss.
Air borne spores produced by moss easily grow in between the cracks of the roof shingles.
Why is moss bad for my roof?
Moss absorbs moisture like a sponge. Normally, rain water will wash off your roof into gutter and drain away from your home. Moss will absorb the rain water soaking it into your roof. The water will eventually find its way under the shingles and through the roof underlayment (water resistant layer). Once soaked, the wood underneath will decay. This can lead to holes in the roof, or in the worst case scenario your roof collapsing.
This can also cause mold to form. If ingested mold can be very harmful and can cause serious illness. Removing mold can be very time consuming and extremely costly!
