Why Moss Is Bad For Your Roof, And How Can You Prevent It

Having moss on your roof can interfere with your curb appeal, but that isn't the only thing you should worry about as far as roof moss is concerned. Moss can cause great damage to your roof, for example:

It May Lead To Water Leak

One of the worst things about moss is that it attracts and retains moisture; it keeps the roof perpetually wet. This means rain water or melting snow water will stay on your roof for a long time if it is covered with moss, giving the water time to soak through the tiles and leak into your house.

It May Lead To Roof Decay

Even if you have the most waterproof roof, it is still not safe from water damage if it is covered with moss. The longer the water stays on your roof the longer it has time to affect the roofing materials, such as wood and metal. Of course, this means the metal will corrode and the wood will decay, and pretty soon you will be looking at roof repair or replacement quotes. If this does happen though, you shouldn't hesitate to reach out to a place like M & M Roofing & Siding Co. 

It May Accelerate the Effect of Frost on Shingle Surfaces

Shingle granules are meant to protect the roof from cold weather damage by absorbing the brunt of weather related damage. In the process, however, the shingle surfaces are affected; the more the shingles are exposed to cold weather the more their surfaces are affected. Moss is culpable in this type of damage too because it traps frost and ensures it stays on the surface of the roof for a long time, accelerating the damage:

Due to the above problems and more, it's in your best interest to protect your roof by preventing moss growth. Here are some of the preventive measures that can help:

·         Use moss resistant shingles; such shingles are treated with chemicals that inhibit moss growth.

·         Install metal flashing or strips on roof edges; the chemical wash offs from the metal prevents moss growth.

·         Use moss-inhibiting treatments on the roof.

·         Keep the roof dry because moss grows better in moist places.

·         Keep the roof clean; keep it free especially of organic debris that encourages mold growth.

Things that grow on the roof, from moss to lichens, are all bad for your roof. If your roof still doesn't have moss, talk to a roofing contractor to help you prevent them. All isn't lost, however, if you already have a moss problem; there are effective ways of removing them.
