Moss Removal for Your Roof

You’ve just had a beautiful, functional roof installed, and you notice it beginning to grow moss. It may feel inevitable here in the Pacific Northwest, but that doesn’t mean it’s any less frustrating. Or maybe you find that moss adds character to your home. Unfortunately, moss is more harmful than it may look. Moss removal and prevention are the keys to extending the lifespan of your roof.

Why Moss is Bad for Your Roof

The trouble with moss is that in wet climates like ours, the moss turns into a mat that can become several inches thick, which then acts like a sponge, soaking up every bit of water that falls. This then soaks into all sections of your roof, potentially wreaking havoc on your new roof. So as lovely as you might think it looks, it’s important to make sure that moss is eradicated.

A Gentle Approach to Removal

You may be tempted to take an over zealous approach in an attempt to rid your new roof of moss, but it’s essential that whether you decide to brush or scrub your roof too harshly as that can also damage your shingles. The same is true of power washing, as this could chip your shingles, or allow water to become trapped underneath your roof, which is the opposite of what we’re trying to do.

Once or twice a year, you can gently brush your roof to remove moss, or, if you’d prefer, there are chemicals that can remove moss.We recommend Bayer 2-in-1 Moss and Algae Killer, Wet & Forget, and Moss B Ware. You can apply these chemicals yourself or hire a professional to do so.

After Removal

Cleaning moss is a seasonal job. If you are proactive, you can take steps which make it harder to grow back after removal. Once your new roof has been cleared of moss, zinc strips or copper flashing can help prevent future moss problems, extending the lifespan of your roof. Additionally, keeping your roof clear of debris like leaves and twigs, which can provide nutrients for the moss, and facilitate its spreading and growth.

Pruning and thinning your trees to allow more sunlight through to your roof can also help prevent moss growth, since it allows your shingles to dry out more quickly after rain.
