Prevent Moss From Growing
The best way to keep moss from growing in the first place is to take preventive steps. After removing all of the moss with a good roof cleaning, you can add copper or zinc strips to prevent moss from growing back. When rain hits these products, particles are released that kill moss before it gets a chance to gain a foothold.
Another great thing about the PNW? All of the big, lush, leafy trees we have! But if those trees are providing shade, or dropping leaves and twigs on your roof, that debris can hold water in place and give the moss a great environment for growth. Keep overhanging limbs away from your roof and that will help keep your roof nice and clean.
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.
- Always put on a helmet when heading to the rooftop
- 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.
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.
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.
The Benefits Of Removing Moss
While you may not necessarily have to remove the moss-covered shingles before a new roof installation, you should consider it. There are many benefits of removing the moss-covered shingles, including:
- Reduce long-term costs: By removing the old roof, you keep the opportunity to double-up roof layers during your next roof replacement. The maximum layers of shingles allowed to be on the roof, according to most building codes, are two. So, once you use this strategy, you must tear off both roof surfaces during your next roof replacement.
- Maintain home value: Are you planning on selling your home soon? A properly replaced roof is more likely to appeal to potential buyers, while a poorly replaced roof may negatively affect your home value.
- Avoid the risk of damage: You can avoid all of the risks listed earlier in this article by simply removing all of the moss-covered shingles.

How To Remove Moss From Your Roof
Greenery overhead should be limited to leaves flushing out tree canopies. If mossy foliage covers your roof, it’s time to get cleaning. Moss grows in areas untouched by sun, so it can develop at a speedy pace on tree-shaded and north-facing roofs. Spreading moss can quickly upholster to roof surfaces, filling in voids between shingles and tiles and reaching under and lifting up roofing materials. This heaving of shingles allows rainwater and other moisture to seep into a roof’s structure to cause decay and rot.
Before you clean moss off a roof, you’ll need to consider how you want to kill the plants and remove the dead layers of moss. After cleaning, you’ll also need to put some defensive measures into play to prevent roof moss from growing back.
How To Prevent It From Coming Back
Now that the moss is gone, how can you prevent it from coming back? Moss thrives in damp areas. Nine times out of 10, moss on shingles will be found on roof slopes that are under large trees. What happens is that tree is allowing organic materials to fall on the roof and is blocking the sunlight from ever allowing the shingles to dry out. By trimming back the limbs, or removing the tree, you will allow sunlight to dry out your shingles properly. Again, we recommend you call a tree expert to deal with the tree!

Tips For Installing Zinc Or Copper Strips
When installing the metal strip its crucial that you do not use nails to hold it in place this will cause leakage when rain drips down along the nail and through the roof structure. Its also essential to ensure the zinc or copper strips are lying thin and as close to the roof as possible, to prevent warping. When warping occurs, the area of the roof beneath it does not get treated by the strips because instead of running directly down the roof, it runs along the strip to a less warped area.
Whichever method you choose, its important to look at other factors that cause moss growth and try to remove these. For example, trimming overhanging trees and bushes will remove shade that moss needs to grow, as well as moving any satellite dishes to areas that wont create shade. The more sunlight your roof is exposed to, the less shade and moisture will be present, so the less likely moss is going to grow.

Moss Removal In Winter
Winter is also not a very good time for moss removal. However, the reasons are slightly different from summer.
First, the freezing conditions of winter, plus the snow , make it extremely dangerous to get on the roof. Of course, youre always required to wear a safety harness when getting on the roof. However, the risk of slipping and falling is still very high compared to other times of the year.
The other reason is that moss doesnt thrive in winter. The icy conditions easily kill moss without any help. So, although youll find traces of mold on the roof during winter, its usually colonies of moss that have been there for a long time. New moss quickly freezes to death when exposed to freezing conditions.
Above all, most moss removal techniques may not work so well during winter. Whether its cutting the moss layers or washing with detergent, your efforts will likely go to waste as the layer of snow on the roof makes it extremely difficult to reach the moss effectively.
Nevertheless, if you decide to remove moss during winter, consider the following
- Hire a pro: The safety risk is too much even with a safety harness. So, dont do it yourself. Instead, find a pro to handle the moss removal process.
- Select removal techniques carefully: This is another reason you should consider hiring a pro. The professional will know moss removal methods that work best in winter.
Washing Powder To Kill Moss
A widely believed approach is that sprinkling common washing detergent powder across the moss will kill it. Then, you can just spray or scrub the dead moss off the shingles to save on expensive professional services.
Experts from Roof Life of Oregon confirm that it is technically true that commonly available detergent will kill moss. In addition, they say, you can physically remove the treated dead moss by spraying it with a high-pressure hose or scrubbing and scraping, although this method is more complicated and expensive than it seems. It takes a surprising amount of detergent to kill moss.
In addition, the cost of a pressure washer or other high-pressure hose adds to the expense of such a project. Furthermore, misuse of such a powerful stream of water can lead to roof damage that would be quite costly to repair.

Why Is Moss Damaging Your Roof
First and foremost, why do you want to remove moss in the first place? Two reasons: 1. It makes the shingles look dirty and 2. It is actually damaging to your roof. Moss growing on a roof can give an impression to a neighbor or potential buyer of your home that the house has not been maintained. It sounds silly, I know, but your roof makes up roughly 70% of the outside appearance of your home. That means, a clean roof gives off a clean impression and a dirty roof does the opposite.
That being said, the real reason you want to remove moss is because, unlike algae, moss actually DAMAGES your shingles! Moss traps moisture which will cause the shingles to stay wet in those areas. This will lead to premature wear on those spots. First, the granules will come off . Then, the asphalt will be exposed and begin to crack and flake off leaving only fiberglass left! Once fiberglass is exposed, it can actually absorb water and lead to interior leaks. Moss also lifts the edges of shingles. This makes them more susceptible to wind damage!
Choose Effective Roof Moss Controls
When treating roof moss, it’s important to use effective products designed especially for roofs. Mosses don’t function like regular plants, so common weed killers and home remedies don’t work plus they can harm roofs. In the same way, keep products meant to kill lawn moss on lawns, but off your roof. Many of the best lawn moss products contain iron substances, which naturally leave rustlike stains behind. The best roof moss products kill roof mosses quickly and effectively without staining your roof or corroding gutters.
Effective roof moss products work on the same principle as lawn moss controls and prevent moss from retaining water. Without moisture, roof moss dries out, turns dark and dies. Highly effective, non-staining roof moss control products come in easy-to-use dry and liquid formulas:
Always follow product label instructions closely, and make sure the label lists your shingle and gutter materials before you treat. Cover any plants right below your roof line during applications. If the products drips down, rinse plants well.
Moss are often concentrated in roof areas shaded by overhanging trees.
