How To Prevent Moss

To prevent moss from growing on your rooftop, remember that moss is attracted to damp and shaded areas. Eliminating either of these items will help reduce moss growth.

Trim tree branches away from your roof to eliminate shading, as any overhang from branches will inevitably shed sticks, leaves, and seeds onto your roof. Remember to remove the twigs and other debris from your rooftop. You should also be sure to clear your gutters from any gunk that can collect in them. Clogged gutters can lead to a buildup of water, which leads to more mold growth.

Zinc and copper are excellent elements for keeping moss growth at bay. By installing zinc or copper flashing strips under you shingles, rainwater will cause a layer of these metals to roll across your roof and prevent or kill unsightly moss growth. Having a professional nail the flashing under the shingles will prevent damage from occurring to the shingle themselves.

Rinse Off The Cleaning Solution

After youve sprayed your cleaning solution on the moss, its time to relax for a little while. Let the cleaner sit for about 20-45 minutes. While its sitting, the chemicals in the solution are killing it and loosening its grip on your roof. After that, you should lightly scrub with a soft-bristled brush and then rinse with plain water using a hose thats on a low-pressure setting.

Its normal if it doesnt immediately come off of your roof. It typically takes a few days for it to dry off and blow away with the wind. If your home still has a lot on it, you might even want to use a leaf blower after a few days to blow off the remains.

Some roofing will require less maintenance than others. Choices include metal and slate. Some roofings types last longer than others, as well.

Twenty years ago I bicycled about 500 miles along the Oregon / Northern California coast and marveled at the number of asphalt shingle roofs carpeted with lichens and moss. The roof growth gave character to many seaside and forest cottages. Though the roofs looked cool, I knew the shingles probably wouldnt last too much longer.

Lichens and moss accelerate shingle deterioration by loosening shingle granules and exposing the asphalt and fiberglass base materials. The granules arent just there to color the shingles they protect the base materials from sunlight and weathering.

About five years ago, I noticed a few patches of lichens growing on the north side of my roof. Like most lazy homeowners, I ignored the problem. Then about two years ago, when the roof looked like those out in the Pacific Northwest, I knew I couldnt put off treating the growth any longer.

Removing moss and algae from a flat roof can seem like a never-ending task. Most homeowners will have noticed that their flat roof is regularly invaded by the green pest, and while it does no damage to flat roofing materials, it can retain moisture, which will accelerate wear and tear on the flat roof. It also doesnt look very nice.

Moss on Roofs

A flat roof of any kind of material can become a host to moss. While it does not directly damage the building, unlike termites, for example, it can shorten the life of wood, metal, asphalt, concrete or clay roofs, simply by encouraging water to stick around in its shallow root system. Moisture promotes wood rot and concrete decay, will erode asphalt in shingles, and can cause staining and buckling in a metal flat roof.

Moss is attracted to northern sides of buildings, where moisture stays for longer they are also prone to grow near large trees, that produce shade, and morning dew, or rainfall which does not move away quickly will also attract moss.

How To Remove Moss On Roof Shingles

If you decide to remove moss or mold from the roof shingles yourself, you need to prioritize your safety. Here are some of the safety measures to consider.

  • Wear soft, rubber-soled footwear for improved traction
  • Remove the moss while standing on a ladder, if possible

There are many methods to remove shingles from the roof, including scrubbing moss off the roof, washing the roof, and applying chemicals. Each method has its pros and cons.

  • Scrubbing Moss off the Roof Shingles
  • Since moss tends to grip shingles quite firmly, you may get tempted to scrub it off. Scrubbing roof shingles is a delicate process that can leave your roof damaged if not done the right way. The damage can be even worse when dealing with asphalt shingles.

    Asphalt shingles have granules that can get knocked off when you apply a lot of force during scrubbing. Using the wrong brush or scrubbing the roof shingles too hard will shorten the roofs lifespan. To avoid damages, use a soft-bristle brush.

    Using a long-handle soft-bristle brush, scrub the roof gently to avoid scratching the roofing material. Brush the roof slowly gently from top to bottom so you dont lift the roof shingles. Do not scrape or bang on the roof, as that may cause more damage.

  • Washing Moss off the Roof Shingles
  • Pro Tip: Be very careful of the water dripping down onto your ladder. It can increase the risk of slipping and cause injuries. Get someone to dry the ladder before you get down.
