In areas where it’s rainy and winters are humid, moss growing on rooftops may be seen among rows of houses with shingles as roofing. Sadly, some homeowners don’t realize that these growths do damage which isn’t just superficial. Many even think that they add beauty, making the surroundings look fresh and natural. Yet, if you leave them untouched for too long, they could wreak havoc and the consequences could burn a hole in your pocket. According to roofing experts of Ohio, the earlier you deal with moss on roofs, the better for you.
What is moss and where do they thrive?
You will find moss on almost any outdoor surface that’s damp. Outdoors, you will stumble upon them on trees, pavements, on the ground, and even on your roof. It is a plant that gives of minute pores and when released into the air, they may land on any surface including the surface of your roof. Moss favors cool, moist places. During dry seasons, they change hues from green to rust. While algae and lichen may also grow on rooftops, moss is more difficult to scrub and could bring serious damage to your roofing.
Is your roof built with shingles? If so, look at the crevices between the shingles. Spores from moss would likely land on these spaces and when the wet season comes they grow rapidly, forming a somewhat green carpet that is thick and luscious. You will also notice upon roof inspection that there are certain areas of your roof that aren’t patched with moss. When a certain area is always exposed to direct sunlight, moss won’t grow in there. On the other hand, moss abounds in areas of your roof that are partly or totally shielded from sunlight.

Moss is similar to a sponge in that it readily soaks up large quantities of water. Now when this happens, your underlayment will also likely get soaked up too. Imagine if you have an underlayment of more than 20 pounds of felt that gets soaked in water. No doubt, you’ve got a big headache coming.
Consequently, your roof sheathing is also affected. Once it gets wet, mold will grow leading to a decayed sheathing. If the decay is so severe, your roof frame may also be affected. This damage often occurs in the attic area. As time goes by, your roof won’t give you the protection you need as it has been compromised by decay long been unchecked. Mold can also spread in your room’s interiors. This damage would need repair to be done only by the experts.
What can be done to prevent moss from growing on your roof?
Now that you know that moss can cause roof decays and can accelerate its age, you would probably ask what you can do now before it’s too late. The best inexpensive way is to religiously clean your roof using a broom at least twice in a year.
