    A clean roof is one of the most important parts of home maintenance nation-wide. This structure is your first and greatest line of defence against the elements. Without protection, wind, rain, snow and even sunshine can act as major players in the destruction of your home or workspace. By making professional roof cleaning and moss removal a part of your routine, you can extend the life of your roof and improve curb appeal.

    An Overview of Your Roof Cleaning Service

    Removing moss and debris from the roof of your home makes the entire house look that much more beautiful. Even if the roof is older or in need of replacing, giving it that little bit of shine can make a huge difference. Whether you are selling your home or staying put, curb appeal is important. The presence of moss can be a huge red flag for potential buyers and home inspectors. Keeping it clear of debris and buildup keeps the roof clear to do its job, protect the home!

    Our Gorillas are prepared to tackle any job at any time. Safety is always first and foremost. Safety equipment maintenance is performed prior to commencing any project, big or small. The roof of your home is going to be one of the first things a potential buyer is going to see. Curb appeal plays an extremely important role in your home’s resale value. Keeping that roof clean and free of debris is a job that needs to be done regularly and properly. Let people see your roof as an asset, not an added expense or liability.

    Understanding Asphalt Shingling

    If your home is equipped with an asphalt shingle roof, and it is a little older, chances are there may be a moss and algae problem. Incorporating a proper maintenance program may be the difference between replacing the roof prematurely and getting the full life expectancy out of the roof. It is not uncommon to lose up to 40% due to moss & algae, or improper maintenance of an asphalt roof.

    The Gorilla rooftop cleaning process follows the “ARMA” procedures and protocol, (Asphalt Roofing Manufacturers Association). Two simple rules to follow when dealing with an asphalt roof:

    • DO: Treat your roof with a cleaning and disinfecting solution
    • DO NOT: Pressure wash your asphalt roof under any circumstance

    Canada has an ideal environment for moss, algae and lichen growth. Educating our clients on invasive growth is an important part of maintenance. Unfortunately, learning about moss, algae and lichen growth is about as fun as watching paint dry, so here are a few quick points to remember:

    Moisture: Moisture is consistently present on your roof. With this, moss and algae growth is inevitable. When moss begins to grow, it holds onto moisture, accelerating its growth rate.

    Shade: The amount of sun your roof gets will determine just how long the moisture is retained. North facing roof tops and/or heavily treed parts of the property will receive significantly more shade so these areas will require constant monitoring.

    Trees: Trees that are close to or overhang roofing provide shade and will allow moss spores to be easily transported to your roof.

    Debris: Needles, leaves and branches all retain more moisture on your roof and will create the perfect conditions for moss growth. Not to mention, the aesthetics of a home with debris build up on a roof can be easily turned around with a proper maintenance program.

    Common questions

    Roof Cleaning — answered

    Do you clear roof drains?

    Yes. Clearing roof drains and scuppers is a standard part of our flat roof service, not an add-on. Open drains are critical for water flow, since a single blocked drain can hold inches of water across the roof and overload the membrane.

    How much water does roof cleaning use?

    Modest amounts. A typical residential roof cleaning uses roughly 150 to 400 gallons, depending on roof size and how much rinsing it needs. That is comparable to a few loads of laundry, so most homeowners never notice it on the water bill.

    Will the chemistry damage my deck?

    The safeguard for decks isn’t avoiding chemistry, it’s bracketing it with water. We saturate the deck before any roof solution is applied, so diluted runoff can’t soak into dry wood, then rinse it again once the roof work is done. Properly handled, the deck is unaffected.

    Should I clean the roof of an inherited property?

    There is a practical reason beyond appearance. Inherited homes often sit with deferred upkeep, and a mossy roof hides whether it is sound or failing. Cleaning it first gives you an honest look at the surface before you decide to keep, sell, or repair.

    Do you inspect the roof during cleaning?

    In Burnaby, a basic visual inspection comes with every cleaning visit. As crews work, they note visible issues like damaged shingles, missing granules, or flashing problems and pass them along, so you learn about concerns early.

    Will the results last between cleanings?

    In Burnaby, soft-wash roof cleaning typically lasts 3 to 5 years between treatments. The chemistry kills moss and algae at the root, so they cannot simply spring back. Local conditions like shade and dampness influence where you land in that range.

    Do you handle estate or large-property roofs?

    Yes. We clean estate and large-property roofs across Burnaby, scaling crews to the job. Extensive roofs may run as multi-day work, but every section gets the same low-pressure soft-wash treatment, no high-pressure shortcuts.

    Do you clean office building roofs?

    Yes. For Burnaby office buildings, we offer commercial roof cleaning scheduled outside business hours. The typically flat roof gets a low-pressure soft-wash that clears algae and moss, with crews working around rooftop HVAC and drains so tenants aren’t disrupted.

    Will my roof look brand new after cleaning?

    For Burnaby homeowners, expect a significant improvement rather than a brand-new roof. Cleaning lifts the algae, moss, and lichen and brings back the shingles’ original colour, but it cannot undo normal age and weathering. The visible difference from the street is real.
