    Lethbridge Roof Cleaning & Moss Removal: The Do’s & Don’ts

    Removing loose clutter is the first step toward a clear roof. By getting rid of these obstacles, our Gorilla technicians have a clear view of the greater condition of your roof. This process, however, does not stop by just picking up debris, it must be taken away as well. If moss is present, it should be removed as quickly as possible. If moss is allowed to sit on damp surfaces, it spreads quickly and can squeeze under shingles. Moss might be pretty but it is also destructive. Once it finds its way under the outer layer of shingles, it begins to pull them away from the decking underneath, allowing moisture into the lower layers of your space. This means damaged decking and the wearing away of materials. It is a good thing that our Gorillas offer local, timely services to the Lethbridge area.

    Common questions

    Roof Cleaning — answered

    Does roof cleaning save energy?

    In Lethbridge’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.

    Will roof cleaning chemistry damage solar panels?

    No. Properly applied, our soft-wash roof chemistry does not affect solar panels. Crews avoid spraying concentrated solution directly onto the array, keep application to the shingle, tile, or metal around it, and rinse as needed so nothing pools or dries on the glass.

    Do you offer ongoing roof inspection?

    Yes, and pairing it with cleaning makes the most sense. Since the roof is clear and crews are already on it, an annual inspection adds little time but a lot of value, flagging small problems while they are cheap to fix rather than after a leak appears.

    Can you clean modern flat-roof homes?

    Yes, modern flat-roof homes are cleaned using a commercial-style approach. Flat roofs drain and weather differently than sloped residential roofs, so the technique follows what we use on commercial buildings rather than standard sloped-roof cleaning, adapted to the membrane or surface in question.

    What if my flashing is damaged?

    Damaged flashing gets flagged in our report. Cleaning can usually still go ahead, since flashing repair is separate work, but we’ll let you know so it can be addressed. Flashing seals the joints where water tends to get in, so we refer you to a specialist for the fix.

    Can you clean TPO or PVC roofs?

    Yes, TPO and PVC single-ply membrane commercial roofs are cleaned with an appropriate, material-specific technique. This is specialty work for commercial buildings, using low-pressure methods that remove dirt, biological growth, and contamination without degrading the membrane or weakening its welded seams.

    Does sodium hypochlorite damage roofs?

    No, sodium hypochlorite at soft-wash dilution does not damage roofs, and the worry usually traces back to confusing it with pressure washing. High pressure strips shingle granules; controlled low-pressure chemistry does not. Dilution and rinse, not the chemical, decide whether materials stay safe.

    Do you serve healthcare facilities?

    In Lethbridge, we clean roofs for hospitals and clinics with operations coordination built in. Because these buildings never close, we plan timing and access around continuous use and keep chemistry and runoff managed near intakes and entrances.

    Where does the runoff go?

    Runoff flows into the surrounding landscape and storm drains, but at safe dilutions by the time it gets there. Pre-rinse and post-rinse steps protect plants directly, and the chemistry is already diluted and breaking down, so it does not enter drainage at harmful strength.
