Moss and algae can cause many problems to your roofing, leading to the need for a roof replacement. Though a small layer of thin moss is not too troublesome, large clumps of moss will degrade shingles and cause leaks.
That’s why regular roof cleaning in Bellevue is important. Note that most moss removal techniques recommended online can further damage your roofing.
So, how can you safely remove roof moss? And, after removing moss on shingles, how will you prevent it from growing back? There are various moss removal solutions specifically made to kill moss.
So, if you’re intent on the DIY approach to cleaning your roof, keep reading to know how to get rid of moss from your roof.
Inspect Your Roof First
Ensure you have at least one professional roof inspection each year to check for developing problems. You can notice problems before they become expensive repairs and plan for regular roof maintenance.
If there is a huge patch of moss on the roof, the roof damage is already significant. In some scenarios, replacing your roof is better than wasting time trying to remove moss.
Take this time to check for leaks, repair shingles, and replace any compromised flashing. Professionals can identify any damage from moss and know how to use moss removal tools.
Removing Moss and Algae
If you settle for a DIY method, first take all the appropriate safety precautions. Ensure you’re using a rubber-footed safety ladder and have someone spotting you.
Also, don’t walk on the roof. Roofers use rubber-soled boots and a safety harness for maximum traction.
If you can’t undertake roof treatment from a ladder, you risk serious injuries. That can cost more than hiring an exterior cleaning service provider.
But, if you can reach the roof moss from a ladder, try following these three steps:
1. Scrub it Off
Be very careful here since it’s a delicate process, and you can damage your roof while scrubbing it. Also, asphalt shingles have tar and oils to protect them from moisture and UV light.
Applying too much force can knock off the shingle granules. Also, a metal roof has protective coatings to prevent corrosion.
Using the wrong brush or scrubbing too hard will shorten the roof’s lifespan. So, how will you clean your roof?
Use a gentle scrub brush and work slowly to avoid scratching your roofing material. Brush shingle roofing from top to bottom to prevent the shingles from lifting.
Note that scrubbing moss on shingles can aid in spreading the spores. You will start to deal with more roof moss in as little as six weeks.
Also, some bits of moss breaking off will still regrow. Missing even a tiny bit of moss with your brush will cause it to regrow fairly quickly.
2. Wash Your Roof
Clear the roof of any debris protecting the moss spores. Avoid pressure washing your roof since you can damage shingles leading to leaks.
Consider using a standard spray attachment for a hose. Watch out for water dripping down onto the ladder to avoid slipping.
3. Kill the Spores
There are several moss removal solutions you can use on your roof. But, it’s common for homeowners to use vinegar or a a mix of 50/50 chlorine bleach since they are very effective. But, they will also kill other plants.
Once the solution lands on your landscaping, it may cause a lot of damage by burning the leaves and disinfecting the soil. A nice way to offset this is by thoroughly wetting your plants before rinsing the roof. DAPrDAN uses a chlorine neutralizing agent in combination with natural fertilizing enzymes that actually benefit your plants significantly.
You can even spread plastic sheeting over sensitive plants and walkways to lessen their exposure, but be careful on hot days so you don’t bake your plants in the heat. Some people prefer leaving the sprays on the roof since bleach and vinegar evaporate fairly quickly.
But, if not mixed, or applied properly, chlorine bleach and vinegar can be harsh to your roof and may break down the protective coating. Also, there are other moss removal solutions on the market formulated specifically for DIY moss roof treatment.
The eco-friendly formulas use moderate ingredients such as zinc salts and baking soda. With several applications, these ingredients can be fairly effective at removing roof moss without further damaging your roof.
Preventing Moss Growth
Ensure your roof has sufficient sunlight throughout the day. That’s because sunshine is the best natural moss deterrent.
Trim all trees around your roof to prevent shade. You will also protect your roofing from falling limbs and animals seeking shelter in your attic.
Note that sticks, leaves, and any organic material attracts spores. Regular home maintenance will prevent moss spores from growing on your roof.
It’s vital to have proper roof drainage to keep things dry and maintain airflow. Consider galvanizing steel roofing panels and installing protective zinc coating to prevent corrosion. Zinc will also discourage plants and mold growth on your roof. If you have shingle roofing, install zinc strips along the roof ridges. As it rains, the water will carry tiny specs of zinc, which kills moss and algae growth before it turns into a problem.
