If you have mold growing on your home's shingled roof, you may assume that the growth is just an eyesore that mars the beauty of your home. However, it can also be damaging to your roof. Below are three reasons why mold on your roof is more than an eyesore.

Mold Breaks Down the Shingles' Material

When you have mold growing on your roof for an extended period of time, the fungal growth can eventually make your shingles deteriorate. In moist, shady areas on your roof, the mold spores are able to find a home.

As the spores grow into mature patches, the moisture that led to them sprouting remains under the growth's cover. Because the shingles remain wet, they start to deteriorate rapidly.

Moisture is not the only thing that makes the roofing material break down. The mycotoxins that are released by the mold saturates the shingles, softening them so more spores can take root. Eventually, your shingles will fall apart.

Growth Shows Water Is Leaking under the Shingles

Another reason why mold on your roof is a bad sign is that the growth is often indicative of water leaking under the shingles. This scenario is especially true if you see mold growth sprouting up from under the shingles.

Since mold gravitates towards dark, wet environments, it can thrive in between your shingles and the underlying plywood if water is leaking under the shingles. Eventually, the chemicals from the mold and the constant moisture on the plywood will make it rot, leading to a leak in your home.

Leaks Can Bring Mold Spores into Your Home

A leaking roof is never a good thing in your home. However, if your roof starts to leak while the mold is growing on and under its shingles, the water coming in will bring mold spores with it. 

Once introduced into your home, the mold spores could cause health problems for you and your household. Compounded with the water damage to your ceilings and walls, you could have a major mold problem in your house on your hands because of the growth on your roof.

After reading about the dangers of having mold on your roof, you may be ready to have something done about it. If so, contact a residential roofing company to schedule an inspection so they can find out the extent of the damage and discuss with you what can be done about it. For more information, contact a professional in your area or visit a website like http://www.americanrenovationssc.com/.
