    Brands the Gorilla Property Services network has worked with across Canada and the U.S.

    There are plenty of reasons to opt for a home improvement. Whether you are looking to add value to your home, create a comfortable commercial environment or are just looking to update for comfort, these things need to be done properly. While many Canadians love a DIY project, your roof cleaning should not be one of them!

    Depending on the area around your home or storefront, roof care and maintenance can be a full-time job all on its own – and a dangerous one! The higher you go, the more dangerous this chore becomes, but that won’t stop clutter from forming. Instead of struggling to hit those heights and get a great result, leave the heavy lifting to a Gorilla and our Calgary roof cleaning and moss removal services. When you enlist our Gorillas for help, keeping your roof clear of clutter and growth is a breeze!

    Roof Cleaning Services: Diagnosing Debris

    Little by little, your roof is collecting debris, all day every day. A cluttered roof not only looks awful, but it can be dangerous to your structure. The most common types of debris are organic but flat surfaces can’t fight off baseballs, frisbees or plastic bags when they come floating by. No matter what lands on your roof, our Gorillas can get it off.

    A simple clearing away can do a lot for the aesthetic of your property, but it can also do a lot for the structural integrity of your home or business. Moss and algae are bad news for roof shingles, but so are improper removal methods. Over time, moss thickens and grows, weaving under and around asphalt shingles and reaching decking. When you want to get rid of moss, a basic scrub brush and chlorine bleach can do more harm than good. There are plenty of property owners who learned the hard way that taking a wire brush to a patch of moss is not the right way to go!

    Harsh methods, like scrubbing or even pressure washing can strip away weakened materials and decking, leaving holes behind. Insects, rodents, and other pests sneak in through these areas, adding another issue to the mix. At the best of times, your roof can last decades before it needs an expensive replacement. Extend the life of your roof, through twice annual maintenance.

    Common questions

    Roof Cleaning — answered

    How much energy does roof cleaning save?

    Treat energy savings as a bonus, not the main reason to clean. The realistic range is a 5 to 15 percent cut in cooling costs, and only in homes where solar heat gain through the roof is significant. Hot climates see the upper end.

    What's the danger of DIY roof cleaning?

    Falls are the danger people underestimate most, and they’re the one that causes serious injury. The others are real too: shingle damage from poor technique, chemical burns from mishandled product, plant loss from concentrated chemistry, and a voided warranty. Together they make DIY a poor trade.

    What if my neighbor used pressure washing on their roof?

    A clean-looking roof next door does not mean pressure washing was the right call. The damage from stripped granules is rarely visible right away, but it shortens the roof’s remaining life. What looks like a win now can mean an earlier replacement later.

    Can roof cleaning be done in summer heat?

    Yes, though extreme heat shortens how long the chemistry stays effective on the roof. To work around it, our crews schedule earlier in the morning or work in shaded sections, which keeps the solution wet and active long enough to do its job.

    Are your cleaners environmentally friendly?

    Yes. On Calgary properties, our cleaning uses biodegradable chemistry at controlled dilutions, with rinse protocols that protect surrounding plants. It breaks down to inert components within days, so it clears moss and algae without harming the landscape.

    Should I bundle roof cleaning with other services?

    Yes, bundling is usually worth it. The common pairing is roof cleaning, gutter cleaning, and soft washing, all handled by the same crew on the same day. It is efficient to schedule, and since debris flows naturally from the roof down into the gutters, the order makes sense.

    Will the cleaning damage my landscape?

    The protection comes from technique, not luck. Pre-rinsing plants saturates them so they cannot absorb concentrated solution, and a post-rinse dilutes anything that drifts down. Done this way, landscape stays unharmed, which is exactly why low-pressure soft-washing is used rather than harsh runoff.

    How do I know if my roof is too old to clean?

    For Calgary homeowners, the clearest signs a roof is too old to clean are heavy granule loss, multiple bald patches, soft spots underfoot, and missing shingles. When several appear together, an inspector assessment tells you whether cleaning still helps.

    Does roof cleaning save energy?

    In Calgary’s hot summers, a clean roof can trim cooling costs. Once the dark algae and moss are gone, the surface reflects more sunlight instead of absorbing it, which keeps the attic cooler and eases the load on the air conditioning.
