Most homeowners don’t closely inspect their roofs on a regular basis. However, you should be aware of any changes that occur to it. One issue to be on the lookout for is mold. While mold growth isn’t uncommon on roofing structures, it is problematic. Here is what you should know. 

Why Is Mold Bad for Your Roof?

Mold usually forms in damp conditions without much sunlight. Thus, if your shingles are in a shaded area, it’s possible mold will develop, which retains moisture and can cause wood rot. This means the structural integrity of your roofing system can ultimately be compromised, resulting in a need for a replacement sooner. 

Mold can also invite rodents, as damp roofing materials can be an attractive food source for pests such as mice and squirrels. It’s also unsightly and challenging to eradicate, though professional cleaning can typically remove it if performed promptly enough. Finally, mold can travel into your home’s interior if left unaddressed, potentially leading to health issues. For instance, people with mold allergies or asthma may experience coughing, watery eyes, and congestion. 

How Can You Prevent Mold Growth on Your Roof?

One of the simplest ways to prevent mold formation is to trim back any trees extending over the top of your house. By eliminating shade, you’ll be less likely to experience mold problems. Clear away any debris that falls on your house, such as wet leaves, by using a leaf blower. 

Additionally, keep the gutters clean so moisture has a place to go instead of backing up onto your roofing materials. Finally, if you have older shingles and mold has been a recurring issue, you might consider upgrading to algae-resistant shingles. You could also have zinc or copper strips installed to keep mold growth at bay.
