⚠️ PRO TIP: The “Granule Rule”
Read this before you hire anyone.
If you see piles of coloured sand (granules) in your gutters after a roof cleaning, the job was done wrong it is time for roof moss removal in Victoria.
Your asphalt shingles rely on those granules to block UV rays. Aggressive pressure washing strips them off. Never let a contractor use a high-pressure wand on asphalt shingles. It can remove granules and prematurely shorten roof life.
The only safe method is manual agitation followed by a gentle rinse. Understanding the difference between soft wash vs pressure washing is critical for protecting your investment. Industry leaders like ARMA (Asphalt Roofing Manufacturers Association) explicitly warn against high-pressure systems.
Being a small business owner myself it’s hard to find committed employees to deliver the final process ❤️. Aneisha went out of her way to retrieve my daughter’s toy that was in the gutter. It did get damaged during the process but she went and got 2 replacements at her own expense. Wow my daughter was super happy. I offered her a cash tip for the extra request but she declined. Very polite and professional 😊.
Aneisha is a fabulous professional who communicated clearly what to expect and did a terrific job.
On time, clean, and considerate. Wonderful job
We just had all our windows cleaned yesterday but Gorilla Property Services. The two teams worked hard and a very professional job was the result. Our 22 unit strata has some challenging windows in amongst tree and shrubs. So all in all a fantastic job for the 2nd year. This company clean all siding and soffetts a couple years ago that make the place look like new. Mike
Joel and Francise very efficent
I just wanted to share how pleased I am with the service our building hired. The team was professional, arrived on time, and worked efficiently. They did a thorough job, Great experience overall—highly recommend!
Aneisha was quick, thorough and friendly
Booking: Toni was fantastic! Went out of his way to find us an appointment time as soon as he could even though they were quite busy on the days that worked best for us. Appointment Day: Aneisha and her team member showed up early, were polite and very friendly. They got to work right away after showing them our dryer vent outside. Aneisha even had me come outside to explain how it was going, what type of venting we had and how often we should be maintaining this type of cleaning. Thanks for the great service!! Would definitely recommend and use Gorilla Property Services again.
Aneisha and her work partner did a fantastic job at our building clearing the gutters and removing moss from our entryway. The before and after photos were striking with our gutters completely cleared. Highly recommend this company. We will be using their services again for sure. Thanks Toni, Aneisha and Francis for an excellent job!! Diane
Gorilla Property Services was a wonderful company to deal with. Toni was on top of all communication, servicing and on budget! Thank you Toni and Team for the great service!
Aneisha was great. She did a fantastic job, even vacuuming behind the dryer to make sure all the dust and lint was gone. Both she and her partner were very polite and friendly. We would gladly have their service again. Thank you.
I am a strata manager, and I have been using this company for the past 2 years and they are great! Toni is very attentive and always goes the extra mile for my clients.
Gorilla just completed their first visit to my strata for dryer vent cleaning, and I was very impressed with Aneisha, their lead technician. She double-checked the location of my dryer vent as the most obvious one has been inactive for years. She took the time to ask questions and locate the active vent, instead of walking away, which I very much appreciate. Thank you for being so thorough, friendly and respectful!
Aneisha and her partner came and cleaned our dryer vents today and did a great job. They were very friendly and professional.
Aneisha and Francis were great. They were fast and efficient and very friendly. They also cleaned up above and beyond. I will definitely be using them for future projects moving forward.
Toni and his team took care of us. Easy to deal with and honest with their assessment of what they could do. Cleaned our dryer vent with little supervision or direction. Added some compressed air treatment to the roof to address excess lint in addition. Thanks so much! Will definitely be requesting the service again next year. Cheers!
Toni was recommended by friends . He put lights high up on a weeping beech tree for me . He communicates well, is very prompt and honest . He is open to ideas and works efficiently. It was a great experience and the prices are reasonable . Thank you Toni !🎄
Just a quick shout out to Aneisha & her side kick who just left our place. They were punctual and friendly,appreciated the floor being covered for them and explained what they had done after they had completed the task. These 2 are keepers! Thanks for the great service:)
Brown bros contacted Gorilla gutter cleaning for the property. I am really impressed with the services. Aneesha and Will did a wonderful job and I will definitely recommend them.
Toni had us do some parking lot painting work. He was great to work with and very professional.
Aneisha and the other worker that came to Hotel Zed were fabulous. We were very impressed with the detail to getting the job done correctly!
Gorilla Property Services was contracted by our strata to perform a variety of services. All services was done professionally, timely, and above our satisfaction. Toni was always available to consult with me. We will definitely use them for all our future needs.
Aneisha did a wonderful job of cleaning our windows! So nice to have clean windows again
Toni and crew did a great job of cleaning our vinyl siding and washing our windows and deck glass. Toni is professional and personable, and a good communicator. Pricing was very reasonable too. It was a pleasure to work with the entire Gorilla team. Highly recommend!!
Amazing work and customer service! We recently got our roof and gutters cleaned and the difference is incredible - looks new again. Toni and his Gorilla team were so efficient, thorough and friendly - I will definitely be booking with Gorilla Property Services again! Highly recommend and will be in touch soon for power washing services. Thanks again :).
Why Moss Loves Victoria (And Why You Should Care)
Victoria isn’t just rainy; it is consistently damp. Data suggests Victoria and the South Island see roughly ~150 wet days a year, depending on the specific weather station.
This constant moisture creates the perfect incubator for moss, algae (Gloeocapsa magma), and lichen.
You might think moss is just a cosmetic issue—a green fuzz that makes your house look like a hobbit hole. You would be wrong. Does moss damage shingles? Absolutely. Moss is a sponge. It anchors itself into the fibreglass matting of your shingles and holds water against the surface for days after the rain stops.
The Physical Damage Cycle:
- Rooting: Moss rhizoids (roots) work their way under the shingle edges.
- Lifting: As the moss swells with water, it physically lifts the shingle. ARMA notes that this lifting increases the risk of wind damage.
- Infiltration: Wind-blown rain is now pushed under the lifted shingle, reaching the wood deck.
- Rot: The decking softens, leading to expensive structural repairs.
If you ignore moss in Victoria or Langford, you aren’t just looking at a dirty roof; you are looking at a premature roof replacement.
The Victorian Gorilla Methodology: Manual Removal vs. Chemical Treatment
We don’t believe in “magic sprays” that promise to dissolve heavy moss overnight. They don’t exist. Real removal requires a hybrid approach: Mechanical Removal followed by Chemical Treatment. You can read our detailed breakdown on how to remove moss from your roof properly.
Step 1: The Manual Demossing (The Hard Work)
This is where most budget companies cut corners. You cannot simply spray a thick moss mat and expect it to die and fall off quickly. It will turn brown, turn into sludge, and clog your gutters for months.
We start by physically removing the bulk of the growth.
- Tools: We use specialised brushes and scrapers with plastic edges, not metal. Metal tools can slice through the bitumen layer of the shingle.
- Technique: We brush down the slope. Directing airflow or brushing down the slope prevents debris from being driven under the shingles, which could break the adhesive seal that protects against wind lift.
- Focus Areas: We pay special attention to the “valleys” (where two roof faces meet). These are high-flow water areas. If moss dams up a valley, water will divert sideways and leak into your attic within months.
Step 2: Air or Low-Pressure Rinse
Once the heavy clumps are bagged and removed, we need to clear the spores and loose debris.
- Air Cleaning: For dry moss, we use high-velocity air blowers. This is the safest method for the roof as no water pressure is applied.
- Soft Wash: If the roof is stained black with algae (often Gloeocapsa magma, which ARMA notes is largely aesthetic), we use a low-pressure rinse system to apply a cleaning solution. This kills microscopic spores without blasting the surface.
Step 3: The Inhibitor Treatment
This is the science part. Mechanical removal, one of the effective moss removal methods, gets 90% of the visible moss, but the roots remain microscopic. We apply a residual roof moss removal spray or inhibitor.
- Our Policy: We monitor the weather closely to determine the best time of year to remove moss. We typically do not apply treatment if heavy rain is forecast within 4 hours. The product needs time to soak into the pores of the moss and lichen.
- The Effect: This helps make the roof surface inhospitable for new spores. It turns any remaining organic matter into a dry powder that washes away naturally with the next rain.
The Cost of Roof Moss Removal in Victoria (2026 Guide)
Pricing in the construction sector can be opaque. We prefer transparency regarding what is included in roof moss removal.
The cost is rarely determined by the square footage alone. It is determined by “time on roof” and “safety complexity.” A steep, three-story heritage home in Oak Bay takes three times longer to rig safely than a walkable rancher in Langford.
Typical Price Ranges:
| Project Type | Estimated Cost | Factors |
|---|---|---|
| Standard Prevention | $300 – $600 | Light moss, walkable pitch, single-story. Mostly air blowing and treatment. |
| Full Removal (Avg Home) | $600 – $900 | Visible clumps, gutter clearing, treatment. 1-2 storey. |
| Complex/Heavy Moss | $1,000 – $1,500+ | Thick carpets of moss, steep pitch (requiring harness), difficult access, 2+ stories. |
What You Are Paying For:
- Labour Intensity: Hand-brushing a 2,000 sq ft roof is physically exhausting work.
- Safety Setup: Setting up OSHA-compliant anchor points and rope grabs takes time before cleaning even starts.
- Product: The best moss killer for roofs isn’t just cheap bleach; it is formulated to protect asphalt integrity.
- Waste Disposal: Heavy moss is heavy. Hauling hundreds of pounds of wet biomass to the compost facility is part of the fee.
Solar Panels & Moss: A Dangerous Combination
If you have solar arrays, moss is your enemy.
We see this constantly in Victoria: the roof looks clean, but the 6-inch gap under the solar panels is packed solid with pine needles and moss.
- The Heat Issue: Solar panels need airflow underneath to cool down. If moss blocks this airflow, the panels overheat. Uneven shading from moss can create “hot spots” that damage cells.
- The Shade Issue: Even a small amount of moss growing on the bottom edge of a panel can reduce output.
Our Solar Protocol: We use specialized soft-bristle brushes for solar glass. Manufacturers like Trina Solar recommend soft cloth or sponges and warn that aggressive cleaning can void warranties. We clear the gap under the panels to restore airflow.
Safety: Why DIY is a Bad Idea
I will not sugar-coat this. Roof work is deadly.
Between 2020 and 2024, local reports citing WorkSafeBC data indicate over 5,400 injury claims related to falls from heights in the construction sector. This includes almost 1,900 serious injuries and 35 fatalities.
Moss is slippery. Wet moss on a sloped roof is like ice.
- The Risk: WorkSafeBC regulations generally require fall protection for falls of 3m (10ft) or more. Without a proper system, a slip usually means hitting the ground.
- The Liability: If you hire a “handyman” who isn’t properly registered, you could be held jointly liable for their unpaid WorkSafeBC premiums. Always ask for a clearance letter before work begins.
Victorian Gorilla carries full liability insurance and WorkSafeBC coverage. Our crews are trained in fall protection. We tie off every single time. It is not worth saving $200 to risk a lawsuit or a broken spine.
Prevention: How to Stop It Coming Back
You cannot change Victoria’s climate, but you can manage your roof’s environment.
1. Tree Management (The Shade Factor) Moss needs shade to thrive. If you have a Douglas Fir branch hanging directly over your roof, you are fighting a losing battle.
- Action: Trim branches back at least 6 feet from the roofline. This increases sunlight (UV kills moss) and reduces the nutrient drop (needles/leaves) that feeds the moss.
2. Gutter Hygiene Clogged gutters hold water. This standing water wicks up into the roof edge (the eaves), creating a constantly damp environment where moss starts its march upward.
- Action: We recommend cleaning gutters twice a year in Victoria: once in late Spring (after the blossoms drop) and once in late Autumn (after the leaves fall).
3. Advanced Protection For homeowners looking for significant longevity, options like GoNano in Victoria BC can alter the shingles’ surface properties to better resist aging and growth.
4. Zinc/Copper Strips For long-term prevention, zinc or copper strips can be installed along the ridge cap to release inhibiting ions during rain.
- Warning: ARMA does not recommend adding strips to an existing roof if it requires lifting shingles or breaking sealant bonds. This is best done during a re-roof or by a professional who can ensure seals remain intact.

| Shingle Safety | Maximum. No granule loss. | Medium. Chemicals can dry out shingles. | Zero. Strips granules & voids warranty. |
| Instant Results? | Yes, bulk is removed immediately. | No, takes months to die/fall. | Yes, but at cost of damage. |
| Long Term? | Excellent (Treatment inhibits regrowth). | Poor (Roots often survive). | Poor (Surface is roughened, inviting moss back). |
Frequently Asked Questions
Q: Will the treatment kill my garden plants? A: We manage runoff carefully. If we are using a stronger treatment for heavy infestation, we bag the downspouts or dilute the runoff heavily with fresh water at the ground level to protect your hydrangeas and cedars.
Q: How long does the treatment last? A: In Victoria’s heavy rain environment, a treatment typically keeps the roof moss-free for 2 to 3 years. However, if you are surrounded by trees, you may need an annual “maintenance spray” to keep it perfect.
Q: Do you do repairs? A: We are cleaning specialists, but we inspect the roof while we are up there. If we see a cracked shingle, a rusted vent, or a failing pipe boot, we will take a photo and let you know immediately. We can often fix minor shingle tabs on the spot.
Q: Why not just scrape it myself? A: Beyond the fall risk, aggressive scraping by untrained homeowners often tears the shingles. We have seen homeowners use metal shovels and gouge holes right through the roof membrane.
