The growth of moss on your roof is more than an unsightly blemish that detracts from the appeal of your home. Moss is a nuisance that threatens the integrity of your home and the health of you and your family.
The shingles on your roof offer an ideal environment for moss and algae to grow because it is an area of your home that is moist and humid, which when combined with the indirect sunlight of shade from trees, allows moss to thrive. The accumulation of leaves from the trees and other organic debris that collect on your roof give moss the necessary nutrients to grow.
Moss holds water on the surface of your roof like a sponge and, over time, the shingles crack and pull apart as the water freezes and thaws, allowing water to leak in and rot your roof. In addition, because moss flourishes near the edge of shingles, it can pry the shingles apart as it expands.
When it comes to moss and your roof, an ounce of prevention goes a long way to saving your roof. Proper care and maintenance can eliminate conditions that promote the growth of moss of your roof and regular roof inspections can detect the early signs of moss growth so you can take steps to discourage the spread of the moss.
Trimming tree branches that are near or touching your roof will deter the growth of moss or algae. Keep your gutters clean and remove any leaves and debris so water can drain properly, eliminating conditions that will allow moss to grow.
You should also ensure your roof is well-ventilated roof to promote air circulation in your attic, preventing condensation from forming in your attic and lead to the growth of moss on your roof.
