What If The Moss Appears Dead
If the weather has been consistently dry, moss may appear to be dead. However, some species of moss can stay alive when dried out for months. All it will take is one rain for it to recover and continue growing. If your moss has dried out, take the opportunity to have a roofer remove the moss from the roof.
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.
Roof Maxx Kills Moss On Your Roof
Our Roof Maxx treatment will kill existing moss on asphalt shingle roofs. After about 3-5 days post-treatment, the moss on your roof will turn brown and die. At this point, the moss on your roof will start drying out and eventually detach from your roof. Once this occurs, the moss will naturally come off your roof either from normal rains or wind. In heavier cases of moss, it will be necessary to still physically remove the dead moss using a soft bristle broom or rinsing with a garden hose. Roof Maxx doesnt guarantee prevention of future moss growth.

Prevent Roof Moss With Metal Roofing
The first and most expensive option to keeping your roof clear of moss is by choosing a roof type that doesnt naturally grow moss: metal roofing. The most common type of metal roofing seen in the lower Mainland are steel roofs, which can be a good option, albeit an expensive one. These roofs do not necessarily repel organic growth, but they dont provide a porous base for moss to establish itself on.
On the other hand, its common in Europe to use Zinc as the primary material in roofing. If youve been downtown Vancouver recently may notice that Christ Church Catherdral just put on a new Zinc roof. If you had seen the old roof you would have known that it had been torn apart by moss and algae.
Choosing the right roofing type may be an effective but expensive option for homeowners looking to prevent moss from growing on their roof, but what about homeowners with existing roofs?

How To Prevent Moss Growth

First, keep your roof clean. Removing buildup and debris on your roof goes a long way in ensuring that moss, algae and lichen have less of a chance of spreading. At least twice a year, be sure to clean out your gutters and downspouts. Remove fallen leaves, twigs, and branches from your roof. Look for punctures, broken shingles or tiles, and other kinds of damage that might allow in moisture. Patch all damage properly.
Second, hire a professional roof cleaning service to remove moss and algae buildup. A professional roof cleaner has specialized equipment that will remove all the grime, dirt, stains, moss and algae from your roof, and industrial cleaners that are environmentally friendly but will kill moss and algae down to the root. This kind of cleaning both removes restores the original luster of your roof and increases its longevity.

The good news is that you can do something about it! Regularly trim your trees so that theres less shade on your roof throughout the day, and remove any trees that are too close to your house or may present any problems in the future.

Do Not Use A Pressure Washer To Remove Moss From Your Roof
When I noticed moss on my roof, my first instinct was to rent a pressure washer and blast it away.
After a few minutes of research, I quickly learned that you should never use a pressure washer to remove moss or anything else from your roof.
High water pressure can damage your roof by lifting and loosening shingles and washing away the granules, which are the tiny pebbles on each shingle.
Maintaining granules is important because they make shingles sturdier and fire-resistant and protect the asphalt coating from UV rays.

How To Maintain Moss
Moss is a nasty little weed that loves to grow in shady and damp conditions and if it starts growing on your roof, can end up causing problems to tiles, gutters and even stop water draining correctly from the roof. Moss is most likely to build upon north-facing roof areas where there is less sunlight and plenty of moisture. If you have moss on roof tiles, then hopefully this article will show you how to achieve moss-free tiles.
It is best to deal with a moss on roof problem before it gets started but once you have a problem, the sooner you deal with the issue the better. Many people think power washers are the best option for dealing with moss on tiles but this has some really serious potential issues. Firstly, the tiles on the roof could be damaged, as could other roofing materials. Secondly, the force of the power washer could actually break through the protective membrane under the roofing material and flood your loft.
The good news is there are a number of moss killers for roofs treatments to get a moss-free roof and keep it that way and here are some of them.

The Negative Side Effects Of Moss
While moss may appear to be a seemingly unthreatening plant, moss truly can cause severe damage to a home. Like most plants, moss grows roots, and as the moss on your roof grows so does its root system, which can burrow under your homes shingles, lifting them and damaging your roof.
As an extremely moisture-absorbent plant, moss growing on a roof or burrowing itself below shingles can cause excess moisture to sit atop your roof and therefore damage the roof and the existing structure below with mold and rot.
Will Vinegar Kill Roof Moss
Yes, vinegar will kill the moss on your roof and is a natural substitute for the bleach and water mixture. The process of removing moss with vinegar is very similar to the process with bleach and water. According to Hunker.com, simply clear your roof of debris, pour distilled white vinegar into a bucket with a few drops of dish soap so it will stick to the moss, spray the mixture on the moss, wait a couple of days for the moss to die, then clear it with a brush or garden hose.

Moss Growing On The Roof
One of the most common signs suggesting that you need to repair or replace your roof is when you notice moss growing around your roof. Moss is not an appealing accent to find on your roof, but rather something that can weaken its structure. Moss may also cause breathing difficulties in some people, plus it can bring out further particles that can make the infestation worse.
But how does the moss develop on your roof? Lets look at what causes moss to grow. As you may notice, it does not take much for moss to grow, although the problem can become dramatic, depending on whatever might happen where you are.
Repeating Moss Killer For Roofs Treatment
How often you need to repeat the roof moss killer treatment you have used depends on what method you have opted upon. Some of the professional moss killing chemicals can keep a roof completely clear of moss for around 3 years without another treatment. Manually removing the moss on roof and using household products won’t last as long but don’t cost as much to do, so if you don’t mind going up on the roof, this might be the option for you.

Can Moss Damage Your Roof
So whats the big deal? A little moss cant cause any damage, right? Wrong.
A small amount of moss is harmless, but if its left untreated, it can cause significant damage and degrade the structural integrity of your roof.
As I mentioned before, moss typically grows in the cracks between each shingle. As it grows thicker, it lifts and loosens shingles and allows water to leak through.
Also, moss absorbs water when it rains and retains it for long periods, which can lead to mold, bacteria, and the decay of the roofs framing over time.

Does Moss Hurt Your Roof
Yes. 100% all moss, even if its a small patch or the width of a lawn, it can create irreparable damage to your roof if left untreated. This type of destruction can cost you hundreds or even thousands of dollars in roof replacement. But dont fret, you may not need to get an entire new roof just yet.
Understand Roof Moss And Damage
Cracks and crevices between roof shingles provide ideal spots for moss to grow and spread. These simple plants flourish wherever moisture collects, particularly on north-facing or tree-shaded roofs. Moss doesn’t need much light or nutrition, but moisture is crucial. In humid areas prone to foggy mornings and moderate winters, a slight dusting of moss can escalate to a serious roof problem.
Left unchecked, roof moss grows into a thick, resilient layer. Established moss acts like a sponge, soaking in moisture from below and above, and keeping your roof constantly moist. Moss creeps under shingle edges as it spreads, prying shingles loose and letting damaging moisture reach the layers below. Damage progresses from shingles to rotten underlayments and damaged framework. Health-threatening mold can develop and travel down walls to affect living areas as well.
Untreated moss gains a foothold in crevices and cracks as it spreads.

Why Shouldnt I Add A New Roof Over Moss
When you need a new roof, it may be tempting to add a second layer of shingles over your existing shingles. Doubling up your shingles can save time and expense on your roof replacement as your roofer doesnt need to remove and dispose of the old shingles. This strategy is convenient for homeowners because the replacement wont take as long or make as much of a mess. However, there are some circumstances where merely adding a new layer of shingles isnt a good idea.
For example, when you have significant moss growth on your roof, simply covering it up with new shingles isnt wise. Several potential problems may occur if your roofer simply adds a new roof over your existing, moss-covered roof. These potential problems include:
