If your roof has moss, you’ll need to know how to deal with it. Here are the questions you need to ask and how to solve the problem.
Moss needs to be removed from your roof for several reasons. The moss will keep the roof damp, causing your shingles to rot. Moss on the roof can also catch debris, such as leaves, dirt and twigs, and this can make the roof rot even faster.
When you spot moss on the roof, the first thing that you will need to do is to take a closer look at your roof. Is the moss the only problem, or are there other condition issues with your roof?
Look at your shingles and see if they have surface cracks curled up edges, small blisters or smooth areas where the granules on the surface have worn off. If you do spot these problems, the issue with your roof might be bigger than just the moss. You probable need to repair or replace your roof. If your shingles are still in good shape, then the next step is to remove the moss.
First you will need to take a few precautions. Start with protecting your plants and the landscaping below the roof. Spray down your plants with water to keep them moist and then cover them with plastic tarps.
Another precaution is to make sure that you have a sturdy ladder, preferably with a roof standoff. Stay off the roof, because the solution you will use to get rid of the moss may also make the roof very slippery.
Mix up a solution of 50 percent bleach and 50 percent water. Use a pump sprayer to apply the solution directly to the moss. Wait 15 minutes and then rinse the roof thoroughly. The moss should die and dry out within a week. It will either wash away on its own, or it could be brushed off.
