Moss on a roof degrades its value over time if left untreated. Not just to the shingles but also wood, metal, and concrete roofs. It often develops on surfaces that sunlight doesn’t reach. So if your roof in naples is under a tree shade or covered by a nearby building, moss can widely spread on it. It’s also common for the north-facing end of your roof to grow moss. You’ll notice it begin in between moist shingles, tiles, then quickly spread under to lift the roof materials. With this happening, more moisture finds its way underneath your roof causing decay and rot to the sheathing below. If a moss-covered roof gets to the point of rot and decay, you’ll have no option but replace it.

When you decide to clean off moss from the roof, you must determine how you want to kill and remove them. When you are through with cleaning your moss-covered roof, you’ll also have to protect it to prevent moss from growing back. The best way to go about this is to involve a roofing expert.

The Process of Moss Cleaning Roofing Systems

Step 1: Get Up on the Roof

Going up the roof is not for everyone. So if you are height phobic or unsure what you should do, it’s better to invite a professional to do the job. Put on anti-skid shoes, your cap, work clothes, rubber gloves, and goggles. A safety rope will also come in handy just in case you slip. Climb to your roof using a ladder. Place it next to the wall of the affected area.

Step 2: Brush Off Your Roof and Hose Off the Shingles

Once you are on the roof, you can brush it off with your bristled brush from the top moving down. Hose the shingles downwards using plain water to remove the remaining loose particles. Don’t brush and hose the asphalt shingles from down moving up because doing this might remove the shingles. Also, avoid pounding, scouring, and scraping the roof because you might cause breakages, cracking, and ripping. High powered pressure hosing is also a bad idea to protect your roof from damage. If you decide to power-wash, use the lowest pressure possible to avoid tampering with the roof.

If you are asking; how do I get rid of moss on my roof without chemicals? Brushing and hosing off the roof is often enough to remove all the moss for some homes. If this is the case for you, skip to the last step to protect your roof from the growth of moss.

Step 3: Use a Cleaning Solution to Eradicate Moss

Use cleaning chemicals to help you completely eradicate the moss problem. This is better done on a cloudy day to avoid your solution from evaporating too fast. Take note that homemade and commercial moss killing solutions may equally da plants. Therefore, remove your pot-grown plants and the flowers nearby then use plastic sheeting to cover all that the cleaning solution might reach. You also want to protect your walls and floors because the product can discolor and damage them.

To help you keep track of your work, section your roof, and work on each segment before moving to the next.

What is The Best Moss Killer for Roofs?

There are tons of popular moss killers out there you can use to remove and keep moss from growing. They come in two general groups: liquid moss killers and dry powder moss killers. You sprinkle dry powders and spray liquid moss killers. Here are some of the common moss killers out there.

Dry Powder

This moss killer requires hands-on use to disperse it on the affected areas of the roof. You need to be sure that rain is coming to take advantage of this product. So, after climbing your roof, you sprinkle it across the roof in several lines about 3 feet apart. The product stays on the roof until it rains and the water mixes with it to kill the moss. You’ll see the results after a week or so.

The downside with this moss killer is the difficulty to spread it evenly on the roof. Even after getting it right, a wind blow is enough to destroy your hard work and blow away your all investment. Another issue is that sometimes it takes several days of heavy rain to get rid of the chemical from your roof. Meanwhile, it will be white streaks on the roof surface.

Liquid Moss Killer

This moss killer is easier to sprinkle because you don’t have to climb on the roof as long as you have enough water pressure. It comes in a container that you’ll attach to a pipe and a sprinkler to remove moss from a roof. They are also much easier to evenly spread across your roof. What you want is to work on a dry roof to quickly be able to track your progress as you proceed. Some of the popular moss killers for floors include:

Bayer Algae and Moss Killer – Bayer is the best moss killer option if you are working on metal roofs. It’s a liquid product that contains potassium soap, acids, and inert components that do not react with metals. And considering that most roofs have metallic components like gutters, nails, cables, drains, and vents, this algae and moss killer is the perfect solution for most homes. Even though it’s easy to use owing to its spray nozzle you should be great at targeting the roof parts with moss, it flows quickly.

Moss B Ware – Zinc sulfate monohydrate contents form 99 percent of Moss B Ware making it a great option for clearing moss on roofs. It’s not just used for moss removal but also very useful in preventing it from growing. Just like you’d use zinc strips at the ridge of your roof, this product can utilize rainwater to protect your roof from moss growth. It’s popular among homeowners because it’s easily available and is less costly.

Moss Out – Another great moss killer is the Moss Out which contains 99 percent of Zinc sulfate monohydrate – just like Moss B Ware. The only difference is that it is less powdery, which makes it easier to apply.

Caution! Some states restrict the application of zinc in the rain because it discharges into local water reserves. Make sure you know what your local state laws say about zinc runoff before investing in such products.

Vinegar or Chlorine Bleach Solution is another affordable solution to removing moss from a roof. Mix one part of vinegar or chlorine bleach and four parts of water then spray it on moss on your shingles. You’ll see the moss breaking down and dying in about two to three weeks. This solution is also perfect to help avoid moss growth on your shingles in the future.

How to Prevent Moss from Growing Back on Your Roof

Regardless of how thorough your moss removal is, without eliminating the cause, you’ll still have moss problems in the future. You already understand that moss grows in wet conditions under shades, and so you should strive to allow enough sunlight to reach all corners of your roof. Observe what is creating these conditions. Then cut down the tree causing the shade or prune branches to let light access your roof.

If your roof is poorly done and traps moisture, you should repair or replace it. Contact a roofing expert to inspect your roof and inform you of the best course of action for a better roof structure.

Installing Strips of Coppers or Zinc to Prevent Moss Growth

To prevent moss from growing on your roof in the future, you should install copper or zinc on it. These metals are toxic to algae and moss. When rainwater runs over the strips and washes over the roof, the environment becomes inhabitable for moss.

The installation process is simple: Employ a metal cutting blade to cut copper or zinc into strips (about 3 inches wide and 3 feet long). Tuck them under the ridge of the roof with parts of it visible. Then secure the strips with nails to be part of the roof. Try your new installations by spraying water on them. Ensure they are in the right position and can withstand the heavy local storms.

Installing copper and zinc might be a stumbling block to the aesthetics of your home. Fortunately, the manufacture of roofing materials has revolutionized and you can now buy shingles with these particles in-built. With such roofing products and proper installation, moss would never grow on your roof.

Why is Moss on Your Roof So Bad?

There are many reasons you should remove moss from the shingles of your roof. Moss growth has the following effects on your home and those living in it.

  • Unlike algae, lichen, and mold, moss is harder to remove on a roof.
  • Their sponge-like nature absorbs gallons of water thus adding weight to your roof
  • Moss grows really fast to leach through the roofing structure and reaches the underlying structure to cause rot
  • It shortens the life expectancy of your roof
  • Reduces the market value of your home if you plan to sell it
  • Once moss has access to the interiors of your home, it can create a good environment for mold, algae, and lichen to grow
  • Can possibly lead to health problems for those who live under your property if it gets inside your home. Can even cause health emergencies for people with asthma and allergy
  • Depending on the extent of damage, moss can lead to a huge financial burden. You might need a remediation contractor and find a roofer near me to help fix the issues you are experiencing.
