Molds can form on roofs placed under permanent shade. These mold stains will result to discoloration and will cause damage to roof shingles if not dealt with early and properly. If left alone, molds can also expose the interior of the attic and crawlspaces to mold spores. If that happens, the interior of your house will be susceptible to molds.
This article will show you the most common conditions why molds develop on your roof and some of the ways to prevent them.
Moisture and Humidity Cause Molds
If the place you live in has high humidity or if you are near a large body of water, mold can be a recurring problem. Mold can form not just on your roof but also on your walls and your entire home. You will notice that if the weather is very humid for a couple of days, molds will start forming. Severe molds will develop especially on roof sections that are shaded and periodically exposed to damp weather.
Molds hold moisture. As a result, the growth of molds on your roof will reduce the life of the roof covering. If you have asphalt shingles or wood shingles for roofing materials, the moisture accumulated on the roof will speed up wear of the shingles.
Houses in freezing climates are more susceptible to faster frost damage and cracking because of the presence of molds. Those in tropical climates are not free from these problems. The growth of molds on your roof will eventually penetrate and separate your shingles if you do not take care of them.
Cleaning Molds on the Roof
As we have mentioned, molds develop if a section of your roof or your entire roof is under permanent shade. If the molds on the roof is a recurring problem, it will be wise to cut the branches of the tree that’s shading your roof or eliminate the cause of permanent shade if possible. If you think that the mold on your roof is still manageable, brushing or raking can be done with utmost care to minimize the damage. It is better to clean a small area first so you will know the extent of the damage caused by molds on your roof.
It is possible to eliminate molds on your roof surface by using a power washer or a soft brush. However, if your roof is really out of shape and the mold has taken over, it is best that you leave the cleaning to professional service providers.
If you think that your roof shingles are really worn out and fragile, it is best to replace them entirely so you don’t harm even the professional roof cleaning company.
