Moss Growing On Your Asphalt Roof? The Damage It Can Cause And How To Get The Moss Off

If you see green areas on your roof, you may have moss growing on it. Moss can cause a lot of damage, so you need to make sure you get the roof cleaned immediately. Below is information on what damage moss can cause, as well as tips on getting the moss off.

Damage Moss Can Cause

When moss starts growing, it first appears on the shingles and below the shingles. It starts out thin, but as it grows, it gets thicker and thicker. As it grows under the shingles, it will lift up the shingles. Once this happens, water gets below the shingles easily. Wood rot will then start, and you will have a lot of leaks in your roof and then down into your home.

Once moss gets on top of the shingles, the shingles will start to deteriorate, which will lead to even more damage as more water can easily get through. Over time, mold will start to grow in your attic. If the mold is not removed, mold spores could then get into your home, which can cause health problems.

If your roof is in a shady area, moss can grow more easily, as sunlight can kill moss. If you have trees close to your home that are creating a lot of shade, you may want to consider cutting them down.

How to Remove Moss

If you have a large amount of moss on your roof, you should contact a roofing contractor. This is because it will be very difficult to remove the moss on your own. The roofing contractor will remove the moss and then closely inspect your roof. If there is not a lot of damage, the contractor may be able to repair your roof. For example, if there are only a few shingles affected, the roofing contractor can remove those shingles and replace them with new ones.

If the roofing contractor finds a lot of wood rot, they will likely suggest that you replace your roof. This may be a good idea if your roof is old.

If you only see a small amount of moss, you can likely remove it on your own. To do this, spray your roof using a 50/50 mix of water and bleach. This will kill the moss, as well as any kind of algae that may also be growing on your roof. Never use a pressure washer, however, as you would damage the asphalt shingles. If you have plants close to your home, cover them up, as the bleach will kill them. Also, when you are finished, rinse your roof well with plain water so you remove all the bleach.

The roofing contractor can give you much more information about this, as well as tips on preventing the moss from growing back again. Contact a home roofing service to learn more.
