Moss and algae on your roof may not seem like a serious issue, and passersby may even think it gives the home a picturesque storybook look at first glance. However, this growth can gradually cause serious issues that may result in extensive roof repairs. Here's a closer look at why removing these substances from your roof is essential.

How Do Mold and Algae Impact Your Roof?

Thick growths of moss grow shallow roots that dig into roofing shingles. Not only will this degrade the roofing materials, but it also retains moisture that can contribute to wood rot and rapidly spreading fungus on the roof. Removing moss and algae keeps water flowing off the roof and maximizes the useful life of your shingles.

Algae don’t have roots, so they usually aren't as destructive as moss. However, you might see green or brown streaks on the roof, which make your house look run-down and poorly maintained. Cleaning the algae off of your roof will boost your property value, which is especially important if you’re listing the property for sale.

How Are They Removed?

To remove moss from your roof and prevent unnecessary roof repairs, use a scrub brush to tear the growth away from the shingles. Dislodging the root structure can be tedious and time-consuming, and accessing the roof is dangerous, so most homeowners choose to call in a professional.

Removing algae growth is often much easier, often requiring no more than some oxygen bleach and a hose. However, it's best to avoid using chlorine bleach, which can degrade your gutters and kill beneficial plants in your yard.

Start by applying the oxygen bleach on a cool day without much direct sunlight. Give the cleanser about 20 minutes to kill off the algae, then spray the roof down with a hose. If you’re uncomfortable climbing a ladder, the best approach is to call in a roof maintenance expert to handle this job for you. They'll be able to clean the entire roof surface more thoroughly.
