Your roofing is essential to protecting the exterior and interior of your home. If you see slimy or fuzzy green, brown, or black growth on the shingles or tiles, you have a mold problem that needs to be addressed. Here's what it means for your property and how to combat it.

What Causes Mold to Grow on the Roof?

Mold grows in shaded places, including under debris. If your home is in an area where the roofing doesn't receive plenty of direct sunlight, it's more likely to develop unwanted growth. 

Generally, growth develops in the rainy and humid seasons. Other common causes include clogged gutters, low-hanging trees, and low-pitched roofs with inadequate drainage. 

Why Does It Need to Be Removed?

In addition to being unsightly, the growth weakens the roof structure, which damages your home. Also, black mold poses health risks to people and pets if it invades the home. The airborne spores can affect breathing, cause skin rashes, and aggravate asthma.

How to Prevent Mold Growth

Pruning tree branches overhanging the roof and ensuring your home is ventilated properly helps prevent mold growth. Upgrading your roofing by using materials that resist moisture is another preventive measure. Options include built-up roofing or asphalt shingles that resist organic growth, including algae. 

You should also regularly remove leaves and other debris from the roof. This will prevent water from getting trapped on the structure. If you see or suspect mold is on the roof, it's wise to contact a professional to inspect, repair, or replace the roofing to address any existing issues.
