Removing Mold From Your Roof

Having green moss covering your roof might give your home an old-world charm that’s reminiscent of a fairy tale, but in truth, moss is more of a nightmare if left unaddressed. The greenery looks lovely, but it can accumulate over time, become mold, and then cause degradation on your roof’s material. This is especially the case if your roof is made of asphalt, wood, and clay, but it can also cause damage concrete and metal. Although moss looks nice, you should remove it from your roof.

Generally, molds grow on the parts of the roof where the sun does not reach. This includes areas that are in the constant shade and in between shingles. Aside from causing discolouration, shingles can rot through the years if not checked. Also, by letting mold thicken and multiply, the bacteria can eventually enter your crawlspace or attic, thus risking the quality of the air you breathe inside.

There are plenty of ways to remove mold from the roof yourself, but if you find that it is beyond your abilities, it’s best to call a professional to get the job done correctly. ABOVE IT ALL ROOFING offers professional, reliable, and affordable roof mold removal services in the Greater Toronto Area and Ontario.

DIY Tips to Remove Mold From Your Roof

Before the problem gets worse, you can deal with the moss, algae, and mold on your roof yourself as a preventive measure. Here are five tried and tested tips to keep in mind when dealing with the mold yourself.

  1. A power washer is handy and easy to use but might damage your shingles if not done correctly. The amount of pressure from such a device can do more harm than good on your roofing. It could also reduce your roof’s water repellency and create more significant problems in the future. When cleaning the moss and mold off, it’s better to use a hose with a nozzle.
  2. If you’re using bleach to clean the algae off your roof, follow this solution: 1 part bleach + 1 part water. Spray the solution onto the problem sites and then let it sit for about an hour before rinsing it off. Use a brush for persistent moss, if necessary.
  3. In case the bleach + water formula does not cut it, even with some brushing, then you can upgrade your treatment to something stronger. Mix 1 cup of trisodium phosphate in one gallon of water and then spray as usual. Don’t forget to let it sit for an hour before washing it off.
  4. Install strips of copper or zinc-coated sheet metal on your roof to prevent moss and mold from returning. Copper is the better option against algae, but zinc will be less costly. When in doubt, consult a professional roofing contractor, so you don’t spend unnecessarily.
  5. Roof cleaning is risky, so be sure to take the necessary precautions. Secure your ladder or, better yet, use a safety harness in case of falls. If the roof is too high, better call the professionals who have the right equipment to ensure a thorough and seamless clean.
