What Is The Best Time Of Year To Remove Moss From Roofs
If you want someone to remove the moss from your roof, the best time to do this is summer. The summer months, while the weather is dryer, is definitely the best time of year to any exterior cleaning work carried out. This is especially the case if you are planning on removing moss yourself, which we would not recommend, but certainly would advise against during winter or autumn.
How To Remove Moss From Your Roof
Clearing the moss from your roof is easy and only takes a few simple steps.
Instead of making your own solution, there are specially formulated moss killers like the Wet and Forget Moss Remover or the Bayer 1-in-1 Moss and Algae Ready-to-Spray bottle . Both products get high reviews, but in my experience, a simple DIY bleach and water mixture works just fine.
Another way to remove moss from your roof is to use a long, soft-bristled brush like this one.
Gently pull the brush down your roof towards the gutter. Never push the brush upwards because you could lift shingles and cause further damage.
First Things First: What Is Moss
Moss is a small, unassuming, and not well known as a flowering plant but is just as complex and extremely interesting.
It performs a vital role in the health and function of our environment.
It belongs to a diverse group of Bryophytes, including Liverworts and Hornworts.
Bryophytes are among the simplest of terrestrial plants.
It is one of the earliest plants to become adapted to live on dry land that has developed from algae.
Moss might be small in size, but it is one of the largest groups of land plants and can be found WORLDWIDE in various habitats.

What Are The Dark Streaks On My Roof
You may have noticed dark streaks across your roof. Given that moss grows upright on surfaces, and algae stays low and flush to the surfaces it grows on, its likely any dark streaks you see are algae.
Algae staining on roofs all start out being spread by wind, birds, and varmints, affecting homes across much of the United States.
This algae normally begins its lifecycle as airborne spores that will settle on your roof, especially those roofs that have asphalt shingles. The northern exposure of roofs has the most chance for algae to survive/thrive because that part of the roof is exposed to the least UV and dries last after morning dew and rain.
As the algae grows and spreads, it begins to look like large black streaks on your shingles.

Is Moss On Roof Tiles A Problem
Yes, moss can cause significant issues for your roof tiles. By growing in the gaps between roof tiles, moss can compromise the ability for your roof to keep out moisture.
It does this in two ways. If moss is allowed to grow on your roof, the moisture that the moss soaks up can cause roof tiles to rot. Secondly the growth of the moss and the moisture it brings will fill the gaps between the roof tiles, which can move & damage the roof tiles. This is because the moisture can compromise the bond between the adjoining materials that ensure the integrity of the roof.

How Does Moss Get On Your Roof
Moss likes cool, damp places that lack in the sunshine. If your roof is not fully exposed to the sun, then it stands a good chance of developing a moss problem. It does not matter the type of shingles you have on your roof, wood, asphalt, etc., If the roof is cool, damp and dark, then moss will take advantage of the situation.
At first, the moss may not seem like a problem. But as it grows, it becomes a natural jack and lifts up your shingles. This action can help water to get under the shingles and cause leaks. These leaks will lead to further damage to your home other than the roof.
The worst type of roof to have is the wood shingle style. Since the wood is porous moss can get a good hold on the shingle and not let go.

Why Should I Remove Moss On A Roof And How
Is moss on my roof a problem?
Moss thrives in damp areas, particularly in shade, where the roof stays wetter for longer. Before long it will spread rapidly and can cause degradation to the roof. Plants will penetrate the surface and retain moisture against the roof surface which can expand and contract in freezing conditions, speed up wear and tear, dislodge tiles, or take over certain roofing materials such as felt completely. Growth can block effective rainwater drainage and can be a reason for insurance companies to refuse a claim. Rainwater captured by moss like a sponge which then leaks through the roof can cause mould growth on interior surfaces. Moss is also attractive to birds which may dislodge it, blocking guttering.
Is it expensive to kill moss on the roof or should I pay a contractor?
SPCB manufactures and supplies our solutions to both contractors and individuals. Some prefer to pay a roofing or cleaning contractor to clean the roof for ease as such companies may have the necessary materials, such as sprayers and scaffolding, and the experience.
However, it is inexpensive to do the same work yourself.
You will need a brush for removing any heavy moss, a sprayer for spraying the moss killing solution, possibly a long reach lance , and perhaps a guard to protect guttering from dead moss fall and the moss killer itself. The equipment can be used again either for maintaining the roof or for other garden tasks.

Why Is Moss Growing On Your Roof
Moss thrives in a cool, moist environment and damp climate. Besides roofs, moss grows on:
- Trees
- Any damp surface
If you find moss on your roof, its likely because your roof is shaded by trees or a roof structure, allowing moisture to stay and causing moss to grow.
A non-vascular plant absorbs water through its leaves instead of roots.
Its seeds, called spores, are tiny one-celled reproductive units that form air-borne and find their way onto roofs via wind.
Once the spores get on the rooftop, they merge in the spaces between shingles and burgeon into thick spongy moss.
Since moss thrives in a damp climate, areas of the roof that get the least amount of direct sunlight, like north-facing sections or areas shaded by tree branches, make it an ideal spot for it to sprout.
Once it establishes itself, it soaks up rainwater like a sponge and can spread across the entire roof and grow a few inches thick.
How Do I Remove Moss From My Roof Tiles
To avoid costly repairs, moss should be removed from your roof tiles quickly. Usually it is best to avoid pressure washing your roof to remove moss. High pressure can cause damage to the tiles and lead to water getting into your roof.
Many people will wonder how to remove moss from a roof naturally. When they see moss on clay roof tiles, concrete or slate, many will try to find how to remove moss from a roof without chemicals. This can be done by gently brushing the moss from the roof or scraping the moss from the roof tiles. The issue with using no chemicals is that the moss is not killed in the process. This means that moss spores on the roof that have not been removed will grow back relatively quickly. Even if homemade moss killer for roofs is used the results are usually limited.

Moss On Roof Shingles: Faqs
If you have ever looked up at the top of your Clayton home and noticed that some patches are a little more green than they should be, you probably have a moss problem. Moss on roof shingles is a common issue, especially with older rooftops that have given moss and lichen plenty of time to grow. Not only does it look unsightly, but moss can also cause some serious damage. Here are some of the common questions homeowners have when they notice these green patches growing on their roofs.
What causes moss?
Moss needs a few things to grow namely, a porous surface where it can hold on, shade to protect it from the sun and a fairly regular supply of moisture to live and grow. Sometimes moss will grow where only one or two of these things are present, but all of them together spell trouble.
This means that moss on roof shingles is more likely with older asphalt shingles or wood slats. Your home is also more susceptible if surrounding trees cast a lot of shade on your roof or if you live in a damp or rainy climate. Dust and dirt that have collected and piled into cracks in your roof may also prove an excellent breeding ground. A patch of moss in the right conditions can easily grow and expand. Lichen, a similar type of plant life, often grows with moss.

Things To Consider Before Removing Moss From Your Roof
Now that you know the variety of issues that can arise when moss starts to flourish on your roof, how do you deal with it? Depending on the scale of the problem, you can try to tackle it on your own, or you might require professional moss removal. First, consider these items before jumping onto that ladder.
Chemical consequences
Trying to remove moss from your roof with household cleaning chemicals can cause more harm than benefits. Some cleaning products have properties that result in unfavourable outcomes like lead flashing when it interacts with roofing materials, which can end up staining both the lead and different parts of the roof. Instead, professional roof cleaners have exclusive specialist products that are better suited for roof cleaning.
Structural damage
Most people make the mistake of walking on top of their roof to clean or undertake any damages. However, roofs can’t carry the weight of a human being and can lead to broken tiles or worseinjury. Unless you’re a trained professional, it’s best to attempt the removal from the safety of your ladder.

Why Is Moss Bad For Shingles
You may feel that a bit of moss gives your roof some charm, just as ivy growing up the side of your house might. While moss may be beautiful, it is a detriment to your roof. Heres why:
Most plants gather water from their roots, but mosses gather water from their leaves. Therefore, they do not mind that shingles, unlike soil, are a dry and relatively nutrient-free environment. They will grow roots directly into the shingles, which can destroy the shingles and create the opportunity for leaks.
When it rains, moss will soak up water and retain it, creating consistently wet conditions on your roof. Moss growth will also interfere with proper drainage of water off the roof as water needs to trickle through or around the moss instead of running straight down to the gutters. The resulting constant exposure to water can degrade shingles.
Over time, moss can also work its way under shingles, lifting them up. This uplift creates opportunities for water to penetrate lower layers of the roof and, potentially, your home.
While minor moss infections may not cause many issues, it is likely to become severe over time. Once you spot moss growth on your roof, you should take steps to resolve it. If you have a severe infection, you may have no choice but to remove the shingles that have been damaged by it. A professional roofer can help you assess what kind of intervention your roof needs.
If Only Some Roof Sections Have Moss Does The Entire Roof Need Cleaning
Just because you cant see moss on certain areas of your roof doesnt mean its not already there and beginning to develop. In its early stages roof moss and algae are completely invisible to the naked eye. Remember, it only takes one moss or algae spore to land on your roof and grow then its off to the races.
