There’s something very quaint and rustic about a moss-covered roof, like something out of a fairy tale. Unfortunately, the damage that moss can cause to your roof and shingles is genuine. Moss can degrade almost any surface on your roof, from wood to concrete. As moss grows on your roof, it gets underneath your shingles, pushing them up and allowing water to leak in and damage the material underneath. It can lead to costly Gutter repairs if not taken care of quickly. Luckily, removing moss from your roof is a fairly straightforward task.
Safety Considerations
The first thing you need to do is get up on your roof and wash away the moss. If the problem isn’t too severe, this might be the only step you need to take. Place a ladder where the moss is and run a hose up there as you climb. Just spray the moss with the hose at a downward angle to wash it away. Be careful not to fall as the roof gets slippery. Once you’ve sprayed the moss down, you can use a soft-bristle scrub brush to remove the rest of it. Be gentle with the brush to avoid damaging the shingles. You might be tempted to use a pressure washer to blast the moss away, but resist the urge – it could break your shingles.
Moss-killing products
If the scrubbing isn’t enough to remove your moss, you might need to try moss roof removal materials. You can buy some at any hardware store or make your own if you’re the DIY type. If possible, wait for a cloudy day so the solution doesn’t evaporate too quickly from your roof. Some cleaners are meant to be left for a while, while others are meant to be washed off immediately. Make sure you follow the instructions for the cleaner you end up using. It might also be a good idea to place a plastic sheet on the ground under where you’ll be working to prevent the cleaning solution from discoloring your lawn.
