Why is heavy roof moss removal more expensive?
When moss has reached the pillow stage, which is common in heavily wooded neighbourhoods like Fairview, Spryfield, and the shaded streets of Rockingham, it cannot be cleared with a simple treatment alone.
What our heavy restoration includes:
- Manual De-bulking: We use specialized brushes to gently remove the moss “pillows” by hand. This clears the bulk of the growth without scrubbing away the protective shingle granules.
- Deep Root Treatment: Our custom ProCare formula is designed specifically for deep-rooted growth. We have refined this treatment to saturate the rhizoids settled under the shingle edges, killing the plant at the source without compromising the roof’s integrity.
- Heavy Moss Cleanup: This process creates a massive amount of heavy, wet debris. We clear the gutters, flush the downspouts, and bag up all the waste from your gardens and walkways.
The key factors that contribute to a roof cleaning quote
- Roof Size: More surface area requires more treatment product, more rinse water management, and more time on the clock.
- Roof Pitch and Access: We’re experienced with steep roofs and difficult access, commonly found in South End Halifax, Bedford, Fall River, and Purcells Cove. These types of properties require extra safety setup and specialized harnesses.
- Roof Growth Severity: Heavy moss and thick algae require a specialized treatment plan.
- Roof Material: Asphalt, cedar, and metal all require different treatment strengths.
- Roofline Complexity: Homes with multiple dormers, deep valleys, and complex gables take longer to treat.
- Property Protection: Safeguarding your siding and landscaping from runoff is an important part of the job.
- Quote Details: A professional quote must clearly define exactly which areas are being treated and what is included, such as gutter cleaning or warranties.
Before you hire a Halifax roof cleaner, ask these 5 questions:
- Are you cleaning the whole roof? Some low quotes only cover “spot treatments” of visible moss growth.
- Is the gutter cleaning included? Moss removal is messy and can clog the gutters and downspouts.
- What is your “Tie-Off” policy? If a technician isn’t following the 3-meter safety rule on a steep pitch, you’re looking at a massive liability on your property.
- How do you handle the moss? If they mention high-pressure washing, keep looking for a cleaner. Soft washing is the only way to keep your shingle warranty intact.
- Is there a roof wash warranty? A reputable local pro should stand by their work.

Halifax Roof Cleaning FAQ’s
How often should I have my roof cleaned?
Roof cleaning in Halifax varies depending on several things, including your location (for example, how close you are to the ocean), the amount of shade from nearby trees, and local weather conditions. Some roofs may need cleaning more often, while others can go longer between washes. ProCare offers a 2-year limited warranty on all roof cleaning services. We can also provide quotes for tree and branch trimming around your roof or home to reduce debris, shade, and the risk of moss or algae growth.
Is it algae or moss on my roof?
Moss often appears as small green, hair-like fuzz or patches. Moss will spread and grow up the pitch of the roof, which causes shingles to lift or curl. The lifting of shingles will eventually bring unwanted water into a building causing moisture damage, wood rot, and even roof leaks. Algae are flat black stains or streaks, with a slimy or slick green sheen. Algae thrives in damp areas and holds moisture, speeds up the rot that will cause your roof to leak
What time of year is best to remove moss from a roof?
While roof cleaning in Halifax can be done above 0°C/32°F, the ideal time of year to remove moss is mid-May through September.
What treatments do you use on the roof?
At ProCare Halifax roof cleaning and moss removal our soft wash solution blends carefully diluted chlorine-free bleach and eco-friendly soaps. It quickly breaks down into oxygen and salt, leaving no harmful residues behind.
Is your roof cleaner safe for pets?
We love our animals, so as a precautionary measure, we ask clients to keep all pets indoors for 3 hours after our roof cleaning process. After being exposed to sunlight and air our cleaning solution quickly breaks down to nothing more than oxygen and common table salt. Our service also includes a pre and post-rinse for any fallen solution.
Is it safe to pressure wash or power wash a roof with shingles?
No! Soft washing is the only safe method for Halifax roof cleaning and moss removal. Pressure or power washing can damage the shingles, resulting in a weakened roof susceptible to leaks and rapid deterioration. Pressure washing your roof could also void your roof manufacturer’s warranty.
Will a roof cleaning treatment permanently stop algae and moss from returning?
No. Roof cleaning and moss removal treatment is not a permanent solution. Unfortunately mold and algae spores can return to the same roof eventually. However, periodic cleanings (every couple years) will prevent them and all other organic growths from returning.
Will your solution kill my plants and grass?
No. We take the proper steps to ensure all vegetation is safe. We use biodegradable solutions which we rinse away thoroughly. This includes a pre-rinse, post-rinse, and cover if needed.
Do you clean all types roofs, including metal and cedar shake?
At ProCare Halifax, we service a variety of roof types. However, there are certain roofing materials and pitches we typically avoid due to safety and expertise concerns.
- Metal Roofs: Due to their slippery nature these are done by a case-by-case basis, ensuring the safety and feasibility of the cleaning process for each unique situation.
- Cedar Shake Roofs: These roofs require specialized care and techniques to prevent damage. Given that such expertise is currently outside our service range, we do not offer cleaning for cedar shake roofs.
- Roofs with a Pitch Steeper Than 6/12: Cleaning a steep pitched roof is also done on a case-by-case basis, factoring in specialized safety equipment and challenges in accessing and cleaning the steep surface, all of which are necessary for ensuring the safety of our technicians.
