    Across the Greater Niagara Region, roofs are often left out in the cold – literally! These fixtures are constantly up against the elements, but they do not often get the attention that they deserve. There is clutter collecting with every day that passes by, but that doesn’t mean that you have to be buried.

    A routine Welland roof cleaning and moss removal helps to keep your space in great shape, boosting curb appeal and prolonging the lifespan of your roof. When you are looking for the best results, in the best time frame, combined with the best in customer service, just call a Gorilla!

    Why Should I Choose Roof Cleaning Services?

    Depending on the size of your property, it can be difficult to spot clutter building up on surfaces. The prime culprit for this buildup is organic castoff. Everyday items like leaves, sticks, pinecones, pods and needles fall onto roofing and sit there, layering over itself and collecting moisture.

    Damp, covered environments are an ideal place for moss growth. Even a touch of moss can be detrimental to roofing materials. Invasive growth, like moss and algae weave under and over shingles, damaging the vulnerable decking underneath. Softened materials can be worn away bit by bit, making way for water leaks, rot, mold and even pests.

    There is no doubt that moss is bad news but improper removal can be just as bad! Instead of scraping or pressure washing these areas, it is important to use a lighter touch to avoid damage. Whether you are dealing with a concrete structure or asphalt roof, our team of experts can handle it all!

    Building a Maintenance Program That Works

    Cleaning off clutter might improve the overall look of your property but it is not enough to keep it in great condition. Once surfaces are clean, our team of experts can assess and treat the level of moss growing underneath. The key to any successful service is a trained eye and great technique from start to finish.

    The right brushes or soft washing process is then used to remove moss. From here, the condition of roofing is assessed and reports are given to owners, where they can make a decision on how to move forward with contacting a roofing contractor or repairs or replacements, if necessary.

    Choosing local care means having a trusted technician who understands the needs of properties across the Niagara Region, from St. Catharines, Niagara Falls and beyond. If there are already Gorillas roaming your property, consider bundling other difficult services like window cleaning, power washing and gutter cleaning.

    Common questions

    Roof Cleaning — answered

    Will the crew return if I'm not satisfied?

    Return visits cover workmanship, meaning anything the crew missed or did not finish properly. Spotted a streak left behind or an area that was skipped? Call the office and we send a crew back at no charge. Environmental regrowth over time is a separate, maintenance matter.

    Do you use harnesses?

    Yes. For steep roof work, generally 8/12 pitch or steeper, crews use a harness with a secured anchor and lifeline. It’s standard safety practice that protects the crew and lets them work carefully rather than rushing across a surface where a slip would be dangerous.

    Do I need to be home during roof cleaning?

    Being present is optional, but a few things are not. The crew needs access to an outdoor water source and a clear path around the house, so unlocked gates and moved vehicles matter more than your presence. Flag any locked access or pets when you book.

    Are the chemicals biodegradable?

    Yes, and the reason is straightforward chemistry: sodium hypochlorite degrades to salt and water rather than persisting as a synthetic residue. Sunlight accelerates the process over a few days, which is why properly applied soft-wash chemistry leaves no lasting trace in the environment.

    Why is pressure washing bad for roofs?

    High pressure strips the protective asphalt granules that shield shingles from UV, which shortens roof life dramatically. It also cracks tile, lifts and loosens shingles, damages flashing, and voids most roofing warranties. The visible growth comes off, but so does the roof’s protection.

    Does my roofing manufacturer recommend cleaning?

    For Welland customers, most roof manufacturers recommend professional soft-wash cleaning, especially on asphalt shingles. Periodic cleaning removes algae and moss before they cause damage, which is exactly the kind of upkeep manufacturers expect to protect the roof’s life.

    Should commercial roofs be inspected during cleaning?

    Yes. Cleaning is the ideal time to inspect, since crews are already on the roof with the surface clear of debris. That visibility lets them spot membrane damage, ponding-water areas, and deteriorating sealant early, which is important for getting full life out of a commercial roof.

    What's soft washing?

    Where pressure washing relies on brute force, soft washing does the work with chemistry. The solution penetrates and kills the moss and algae at the root, so only a low-pressure rinse is needed to clear it. That is what keeps roofs intact.

    Can you clean roof edges and drip edges?

    The drip edge is the transition point where the roof hands water off to the gutters, so it stains and collects debris heavily. We clean these edges and fascia areas along with the main roof, leaving the whole lower band consistent.
