How To Remove Moss From Shingles On A Roof

Easy Moss Removal From Tarmac

So, youve noticed something fuzzy and green growing around the shingles on your roof. Sounds like moss. Dont panic, but its time to take action. Letting it stay on your home for an extended period of time will allow it to grow, loosen shingles, and let water leak through. This can damage the structural integrity of your roof. Fortunately, there are steps you can take to remove the moss on your roofing and prevent it from coming back. If youd prefer help from professionals, you can always hire a company to do it for you.

If youd prefer to do it yourself, ready to get to work? Its time to roll up your sleeves and show it whos boss. Heres how to get rid of moss on your roof:

How Do I Remove Moss From My Roof

There are numerous ways you can remove moss from your roof, depending on how significant the spread is already. If its only in the early stages, small patches of moss that havent rooted themselves into your roof space significantly can often be washed away with a hose pipe. Moderate pressure from most garden hoses should be enough to uproot juvenile moss, which wont have worked its way into your roof tiles just yet. However, the tiniest segment of root can soon become moss again, so its vital to remove every trace from your roof when cleaning it. No matter how significant the problem, you should avoid using a pressure washer, as this can cause damage to your roof tiles.

Clean Out Your Rain Gutters

Rain gutters should be cleaned out about twice a year or as needed, depending on how much debris they tend to accumulate. Trimming or removing trees should help, but leaves and debris can still get stuck on the roof or in the gutters, causing them to become clogged. If the gutters are clogged and overflow onto the lower roofs or stop draining altogether, this would be good news for the moss and bad news for your roof. Fortunately, you can prevent that from happening by staying on top of your regular gutter cleanings. Also remember to check your downspouts and make sure they drain at a safe distance from the house. You can either contact gutter cleaning professionals or grab a ladder and do it yourself.

Maintenance Solutions

To understand how to deal with the recurring problem of algae and moss growth on rooftops, it is important to learn what they are and how they grow and spread. Although some similarities exist, algae and moss are very different and require slightly different procedures to prevent or to remove.

Often mistaken as mold or mildew, the black discoloration and streaks visible on many roofs across the United States and Canada are actually algae. The algae can form w here moisture tends to dwell on roof surfaces. Coastal or humid climates create the most conducive conditions for algae growth. The most common type, gloeocapsa magma or blue green algae, protects itself from damaging ultraviolet rays by producing a dark pigmented sheath. The algae discoloration typically begins as small spots then quickly transforms into streaks on the roof plane. By the time the algae is visible, it likely has been present for several months or longer.

Moss is a non-vascular plant that obtains water through its leaves, unlike most plants that gather water through its root system. Moss must therefore have a moist environment to survive. In North America, moss tends to grow on north facing roof planes that receive less direct sunlight and stay damp longer than south facing planes. Overhanging tree branches provide additional shade and drop debris on the roof that further holds in moisture and acts as a food source for moss.

How Is Moss Damaging To Roof Tiles

Moss can cause significant damage to your roof in a number of ways. Tiny moss spores can land in the spaces between tiles, grow, and end up pushing up tiles, causing breakages and structural damage. Moss can also capture a lot of moisture which it will then cling on to. This can cause issues as the moisture leads to the production of mould and mildew, this can cause decay to form on areas of your roofing, and also can allow moisture to trickle into your home through the compromised areas.

Will Laundry Detergent Kill Roof Moss

Collecting & Identifying Moss

Do not put Tide or any other laundry detergent on your roof. Laundry detergent is a de-greaser. It loosens the tar and pulls oils out of the shingles, causing the loss of granules. Despite what some articles claim, avoid using laundry detergent. There are so many other formulas to use, like vinegar, bleach, and solutions specifically made for killing moss, why risk it?

Should You Remove Moss

When you get a roof replacement, you may want to have your roofers install the new roof over top of the old. In certain circumstances, this can help you save money. However, if your old roof has moss growth, can you still use this method?

You may need to deal with the moss before the full roof replacement. Your roofers will need to remove all the shingles on your old roof, or they may need to remove the largest chunks of moss with a pressure washer and then apply the new roof. It is only advisable to use a pressure washer because you no longer need to worry about the condition of the old roof. The new one will offer the protection your home needs.

Why Is There So Much Moss On My Roof

Moss thrives in cool, damp environments, and most of its spores tend to be produced during the spring and fall seasons. If there are parts of your roof that dont get much direct sunlight throughout the day, then they can be more susceptible to outbreaks of moss. The longer it is able to exist, the more it will grow across your roof and even between and under the shingles. Its best to have a roofing professional inspect it to see whether you need to replace your roof altogether or just remove the moss and make any necessary repairs.

    How To Prevent Moss On Your Roof

    Happily, there are preventive measures you can use to keep your roof moss-free. First, let the sunshine in. Trim any branches hanging over your roof, keep the gutters free of debris, and regularly remove moisture-collectorssuch as leaves, branches, and seedpodsthat pile up on the roof and encourage moss to grow. The best long-term solution is to attach strips of zinc or zinc-coated metal flashing strips just below the peak or ridge caps. When it rains, water flows over the metal strips leaching out moss-retardant zinc particles, which attach to roof shingles and/or tiles to stop new moss from forming.

    Working safely, smartly, and strategically guarantees your operations will run smoothly. These prevention measures mean you’ll be able to stay off the ladder and roof for seasons, if not years, to come.

    Prevent Moss On Roof?

    Moss can grow back remarkably quickly, which is very frustrating to see when you have either cleaned your roof or had your roof cleaned by a company. However, there are a few things that you can do to prevent moss from growing back so fast:

    • Trim back tree branches that are overhanging your roof this will prevent moss spores from being transferred to the roof tiles from bits of branches and leaves.
    • Regularly clean your roof and gutters This will take off any smaller spores before they have a chance to start growing and becoming bigger and harder to remove. Moss has a tendency to clog up your gutters too, so its important to make sure you dont neglect to clear them out.
    • Use a moss killer solution This can be applied after a thorough clean to make sure that moss growth is prevented for as long as possible. These types of solutions tend to prevent growth for a while, but can be dependent on factors such as weather and the type of solution you use. For instance, here at ProJet, once we have completely cleaned and cleared the roof of moss, we apply a professional and powerful moss killer which will prevent regrowth for around 18 months.

    These tips should help you to prevent moss growth on your roof for much longer. Keeping your roof maintained and professionally cleaned will help prevent damage and keep moss build-up away for longer.
