    A bit of moss growing on a stone fence or vines growing up a wall can give properties a rustic look but when you begin to notice moss on your roof, it is a problem. Throughout Ontario, homes and businesses are at the mercy of moisture. Invasive growth on your roofing not only starts to look awful, it can cause structural damage as well. Hiring a professional for your Newmarket roof cleaning and moss removal can help to improve visuals, prevent damage and protect your property.

    Roof Care: What Is Weighing On Your Roof System

    Roof clutter can collect over a period of months, or it can feel like it comes out of nowhere. All it takes is one strong gust of wind or heavy rain to dislodge organic debris from surrounding plants and trees. As leaves, sticks, seed pods, pollen, pinecones or other materials fall, they will need somewhere to land. Plants depend on water to survive so they are built for holding onto moisture and that is exactly what they will do, even when sat on your shingles.

    Piled up debris creates a blanket across your roofing surfaces. This blanket holds moisture, blocks out the sun and creates an ideal environment for moss and mold to form. Once formed, moss spreads across surfaces, weaving over and under asphalt shingles, until it reaches vulnerable areas. When moisture reaches wood decking, it can lead to rot and softening.

    Removing moss with a hard wire brush or power washing roofing, can strip away protective coatings and softened decking. This can contribute to water damage, infestations and other unexpected issues. Moss growth also makes surfaces slippery, paving the way for injury. All it takes is one misstep to fall off of a roof, but hiring a professional roof cleaning service means access to top of the line safety equipment.

Roofing companies are quick to install new roofs or provide repairs or replacements but when you want the best results for your regular cleanings, Gorilla is the way to go! Taking a DIY approach to roof cleaning can lead to damage, but it can also lead to personal injury from slips, falling ice dams or unexpected breakage.

Our multi-step approach uses environmentally friendly cleansers and moss killers, as well as customized treatment plans.

    Common questions

    Roof Cleaning — answered

    What is the black streaking on my roof?

    Gloeocapsa magma, a wind-spread algae species that streaks asphalt shingles dark grey or black. It is most visible on north-facing slopes. The algae holds moisture against the shingle which accelerates granule loss — visible streaks usually mean 3-5 years of shingle life lost if left untreated.

    What does a Gorilla roof cleaning include?

    Roof assessment from ladder and edge platforms (no foot traffic on the slope unless required), landscape protection at the eaves, soft-wash chemistry application with low-pressure rinse, manual debris removal where needed, and post-clean visual inspection for damage worth flagging.

    Do roofs here actually need cleaning?

    For most Newmarket properties yes, every two to three years. Even in continental climates the algae species that streak shingles (gloeocapsa magma) accumulates over time. Cleaning is partly cosmetic and largely about shingle longevity.

    Will roof cleaning void my shingle warranty?

    Only if done wrong. Pressure washing voids the warranty for every major manufacturer; documented soft-wash with appropriate chemistry generally does not. CertainTeed and GAF explicitly accept soft-wash. Ask for a written description of method and chemistry — that documentation protects you in any future warranty claim.

    How do you handle slate or cedar roofs?

    Slate cannot be walked on; crews work from edge platforms and ladders only. Cedar needs gentle bleach-based cleaning and oil treatment to prevent drying and cracking. Both require specialty crews. Standard asphalt-roof crews are not qualified for either.

    Will pressure washing damage my asphalt shingles?

    Yes, almost always. Direct high-pressure spray strips granules, voids manufacturer warranty for every major brand (CertainTeed, GAF, IKO, Owens Corning all exclude pressure-washed shingles), and shortens roof life by years. Soft-wash is the only safe method — chemistry-based, low pressure.

    What about skylights and solar panels?

    Skylights — soft-wash chemistry is safe on modern double-pane glass but rinse must be gentle. Older acrylic domes (15+ years) can cloud under chemical exposure. Solar panels are typically cleaned with deionized water and microfibre rather than shingle chemistry. Confirm both during the quote.

    Can I clean the roof myself?

    Strongly not recommended. The combination of roof slope, height, and shingle grit makes ladder-to-roof work among the highest-injury home maintenance tasks. Manual scrubbing of asphalt shingles dislodges granules even at light pressure. Professional soft-wash is also more effective than retail chemistry.

    How much should I expect to pay for roof cleaning near me?

    Pricing scales with square footage, pitch, complexity, and access. Single-storey simple gables are at the lower end; multi-storey with multiple peaks and complex valleys is several times higher. Slate or cedar requires specialty pricing. Site quote beats a flat rate.

    Best time of year for roof cleaning?

    Late May through September. Surface temperatures need to be above 5°C for cleaning chemistry to work. Frozen shingles are also more brittle. Peak window is late June through August.
