Stop Roof Algae From Coming Back

How to clean moss off a roof for less than $15

To keep the algae from coming back, insert 6-inch-wide strips of zinc or copper under the row of shingling closest to the roof peak, leaving an inch or two of the lower edge exposed to the weather. That way whenever it rains, some of the metal molecules will wash down the roof and kill any algae trying to regain a foothold on your shingles.

You can probably see this same principle working on roofs in your neighborhood. Look for chimneys with copper flashing the areas directly below the flashing will be free of any algae stains.

The strips also work on roofs suffering from moss buildup. Just scrub it off first with a brush, then bleach as above.

Factors Affecting The Cost To Clean A Roof

Various factors impact the cost of cleaning your roof, starting with its size. Naturally, larger roofs require more time to clean on average, so professionals usually charge per square foot. Expect to pay a higher price if you have a larger-than-average roof.

Another factor impacting the roof cleaning cost is your location and the surrounding environment. If you live in a rainy area, there is a higher chance of algae and moss growing on your roof, so it may require more regular cleaning.

Those who live by the beach may also find that their roof may be regularly damaged by the salty air and needs to be cleaned more often. If you live in an area with lots of trees nearby, leaves and debris are more likely to build up on your roof, which also leads to the need for more frequent cleaning.

The labor costs also vary from one state to another, depending on the general economy and average income in each area. For example, the cost of cleaning a roof in California is different from cleaning a roof in Idaho.

There is also the roofing material to consider. Some materials like wood or tile need to be treated with more delicate care and attention than others.

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.

    Roof Cleaning Cost Everything You Need To Know

    One of the easiest ways to tell if a roof is likely to need some maintenance in the next few years is to find a roof covered in moss & algae.

    Once algae and moss begin to grow on a roof, it doesnt take long to get out of control. The roots of the algae will take hold in any weakness in the roof tile. As the roots grow longer, cracks will begin to appear in the roof tiles.

    The slates or tiles on the roof will become damaged or loose, and they will need replacing. Moss and algae depend on rainwater to survive. When it rains, these plants act like sponges, and theyll soak up as much water as possible. Its only a matter of time before the rainwater seeps through the cracks in your roof and causes water damage.

    When roof moss gets out of hand, it will begin to roll down your roof and fill up your gutters with moss. Once the gutters are full of moss from the roof, the rainwater will overflow. The water from overflowing gutters will splash on the floor below and cause damp.

    The cost of roof cleaning will depend on the size of the property, roof access, and cleaning method. The average roof cleaning costs are between £5 and £12 per square metre. Sealing the roof after cleaning would cost extra. The cost of sealing a roof after cleaning can be anywhere between £25 and £40 per square metre.

    How Often Should I Clean My Roof And Guttering

    How often a roof should be cleaned can depend on the location of your property. In general, a roof should be cleaned every two or three years, but you will know when your roof looks dirty or has moss or algae growing on it.

    Roof cleaning should not be a DIY job. Even a gently sloping roof will become slippery when water is applied. This is doubly true for heavily soiled roofs or roofs with algae or moss growing on them. Professional roof cleaners know how to clean roofs safely because they do it every day and will take all necessary safety precautions.

    Guttering should be cleaned at least once a year before the winter rains set in. You can’t see the inside of the guttering from ground level, but if you get on a ladder, you might be surprised by the number of leaves and debris it’s collected. Even small amounts can dam the guttering when rains come.

    If you have a single storey home, cleaning guttering can be a DIY job, but only if you feel comfortable working on a ladder and have a ladder high enough to work safely from. If you’re not comfortable working on a ladder, or you have a two-storey home, get professionals to clean your gutters.

    Gutter cleaning is not expensive. For a small home, it may cost around $100. For a larger home, it can cost $200 to $450.

Expect to pay more than the average.

    Roof size and shape

    Small roofs $90 to $150

    Medium roofs $150 to $300

    Large roofs $300 to $550
