How Much To Charge To Do Roof Cleaning? Roof Cleaning Pricing

While clay and ceramic tile are not soft like asphalt shingles, they are not meant to withstand high pressure washing or the weight of someone walking on them! Clay is also somewhat porous, so high-pressure cleaning can damage its surface. Because a roofing contractor might need to use added caution when accessing clay and ceramic tile, he or she might charge a slight bit more than when cleaning asphalt shingles.

How Much Does Roof Cleaning Cost

Roof cleaning, like other roofing projects, is a job for professionals, not homeowners. When you hire a professional roof cleaner, expect to spend between $374 and $606 for a national average cost of $490.

How big is your roof? What material is you roof made of? These factors and others will decide your exact roof cleaning cost. Typical prices range from $0.15 to $0.68 per square foot.

How Often Do You Need To Clean Your Roof

Most homeowners would do well to schedule roof cleaning every other year or every three years at most. However, it might be beneficial to schedule this work more often for your home, if the roof should get especially filthy throughout the year.

As an example, if your house is located near a busy highway or airport, you might notice thick layers of soot and air pollution residues on the roof building up before too long! Annual power washing can clean those away and ensure the roof is clean and pristine.

If there are lots of mature trees on your property, you might also notice that your homes roof is consistently covered in leaves, moss, seeds, twigs, and other such debris. Homes and businesses near the beach are also typically covered in sand, silt, and other gritty debris! If this describes your house, schedule roof washing as often as needed to remove that damaging debris and keep the roof clean.

The Length Of Time Needed

The amount of time needed to clean your roof will largely depend upon:

  • How much moss, lichen and dirt have built up over the years.
  • The size of your roof
  • Other factors, such as ease of access and the difficulty of working up there

If you get an experienced roof cleaning company to take a look at your home, then they should be able to give you an accurate estimate of how long it will take to complete the work.

Why Should I Have My Roof Cleaned

Houses and buildings are regularly exposed to harsh exterior elements like pollution, road dust, wind, rain, saltwater and storms. The moisture of these elements that stick on the roof becomes a breeding ground for mould, mildew, moss, lichen, algae and other bacteria. Over time, the elements in combination with moisture build-up can form cracks, leaks, and holes in a roofing structure.

This unsupervised growth of bacteria and debris build-up is the number one cause of broken roofing materials and roof leaks. The best way to avoid these elements damaging your roof is to have your roof regularly cleaned to maintain the condition of the roofing materials, while simultaneously keeping your roof looking its very best.

Roofing materials are designed to withstand the elements, provide structural integrity, and protect the interiors of a home or commercial property. However, even the sturdiest of roofing structures will suffer from inevitable vulnerabilities and need regular maintenance. While your roof may not require frequent repairs, regular professional roof cleaning is the best possible route to keeping your roof safe from vulnerabilities.

On the other hand, a less professional roof cleaning company may charge just to pressure wash your roof for a lot cheaper. You should never pressure wash a roof. Pressure washing, or jet washing, will be detrimental to your roof and cause a great deal of damage to the tiles and shingles.

Roof repairs or even replacements will cost a lot more than just getting your roof cleaned by an expert in the first place. Pressure washing damages the shingle, stripping it of its protective layer, and can even cause water damage to your property. Remember to look at reviews and see what other customers have said about the company you are thinking of using before getting in touch with them.

    Faq About Roof Cleaning

    1. Can you power wash a roof?

    Most professional roofers dont recommend power washing roofs because the intense pressure can damage or loosen shingles and tiles. However, metal roofs are solid and durable enough to power wash.

    2. Can you clean your own roof?

    No. Most importantly, it isnt safe for you to get up on the roof. Another reason you should always hire professional roof cleaners is that they have access to better equipment and cleaning products than the DIY kits you can buy at the hardware store.

    3. How often should you clean your roof?

    Roof cleaning at least once every year can make your roof last longer. Your roof might need more frequent cleaning if you live somewhere with a lot of wet weather or another climate that exposes your roof to dirt, moss, or salt.

    4. Do you need to clean solar panels on your roof?

    Its true that dirty solar panels are less efficient than clean ones, but you usually wont have to worry about cleaning them because rain will wash off dirt and debris for you. If you live in a very dry climate where it doesnt rain often, you may need to clean your solar panels occasionally.

    Will The Moss On My Roof Grow Back

    Roof Moss Removal

    Unfortunately, yes. Moss is a persistent growth and will return to your roof, sooner or later. A north-facing roof will see the moss return in around three years. You can extend this time by up to five years if the roof is power washed and treated with a sealant.

    For a south-facing roof, you can expect to add an additional two years onto the time it takes for the moss to grow back. Lucky you!

    • Extra services. You might also want to opt for additional services. For example, you might decide to add on gutter cleaning. Keeping your gutters free of debris is another important part of home maintenance.
    • Roof replacement or repairs needed. When you hire a pro, they might find that you need some repairs or you need to replace it. For example, you may have missing tiles or shingles, cracks, damaged flashing or broken gutters that need to be fixed.
    • Location. Perhaps one of the biggest differentiators in costs is your location. The cost of living in your area plays a role in how much any service will cost.
    • Square footage. Before any accurate quote can be provided, a contractor might need to know your roofs size. Some projects are quoted on a square footage basis. If you arent sure how large yours is, ask the pro to provide an in-person quote.
    • Material. Certain roofing materials might be easier for the contractor to clean than others.
