How to remove moss from your roof


Moss on the roof of your houseMoss may look pretty, but when you see it growing on your roof, it’s time to be concerned. Moss can grow directly into shingles, and when it does, it can wreak havoc on your roofing system. Once moss starts to spread it can cause leaks. Once that happens, you may need to replace your damaged shingles.

Moss is particularly problematic for roofs because, unlike most plants that get water from their roots, moss gets water from their leaves. Once moss plants start growing on a large surface like a roof, they can attach their roots and grow rapidly. Unless you act fast, the moss growth can damage the shingles and your roof’s drainage system.

Five steps to remove mold from your roof   

When you see moss on your roof, it’s best to remove it. Luckily, it’s easy to get rid of it  with items you likely already have in your house and a cleaning mixture of chlorine bleach or detergent, and water. Take a look at the steps below.

1. Create a cleaning mixture of eight ounces of dish soap and two gallons of water. Or you could mix two cups of chlorine bleach with water.

2. Make sure your ladder is safely secured to your house and then spray the mixture on the moss. Let it sit and permeate the moss for 20 minutes.

3. After waiting, spray the area down with your hose on a low-pressure setting. Remember to be careful when spraying water on the shingles. If the pressure is too strong it can damage them.  

4. If some moss remains once you’ve sprayed the roof, manually brush the moss from the shingles and dispose.

5. Still have moss on the roof even after you’ve cleaned it? Resist trying to scrub or pressure washing it off. Instead, call a CertainTeed Roofing professional.

As the moss takes hold and the root system penetrates your shingles, the moss can seriously degrade the structural integrity of the roof, cause permanent damage to your shingles, and lead to even mor serious problems.
