Preventing Microbial Growth On Wood Shake Roofs

Posted on: 26 January 2022


Mildew, mold, moss, lichens, and algae all have one thing in common — they can grow on the surface of your residential roof and cause problems. If you have a wood shake roof, the odds of facing a microbial growth problem are even higher because wood is more susceptible to fluctuating weather conditions than its non-wood alternatives.

While there are a variety of ways to remedy microbial growth on wood shake roofs, the best practice is to be proactive whenever possible. With that said, here are some useful tips to help you prevent microbial growth on your home's wood shake roof.

Ensure Proper Roof Drainage

If the gutter, downspouts, and stormwater drains that are responsible for allowing fast and efficient drainage of roof runoff are clogged with debris, the water may remain on the roof's surface longer, increasing the risk of microbial growth.

One of the most effective ways to protect your residential wood shake roof against microbial growth is to make sure the roof drains are working properly, especially during the rainy season.

Ensure Your Roof Receives Enough Sunshine

Look around your house. If there are large trees growing near it, you'll need to make sure your roof isn't too shaded. 

Tall trees can form a canopy over your roof, making it difficult for the roof to get sufficient sunlight. This will make your wood shakes remain wet longer, thus encouraging destructive microorganisms to grow on your roof.

If you don't want to cut down the adjacent trees, be sure to trim them from time to time so that they do not block sunlight from reaching your roof.

Keep Your Roof Clean

A clean wood shake roof isn't just good for aesthetics but for preventing biological growth too. If left unchecked, falling leaves, bird droppings, and other foreign substances can trap moisture and encourage destructive microorganisms to grow on your wood roof.

To prevent this from happening, you should arrange a thorough cleaning of your roof on a regular basis.

Taking steps to stop destructive microorganisms from growing on your wood roof rather than responding to the problem after it has occurred can not only minimize your roof repair bills but also extend the roof's lifespan. It also helps you maintain the exterior appearance and beauty of your home.
