Hammonds Plains’ mature tree canopy provides excellent privacy, but it also prevents your roof from drying out after rain or morning dew. This persistent dampness, combined with organic debris like pine needles and leaves, allows moss and lichen to take hold much faster than in more open areas. A professional soft wash every few years is the standard for maintaining a healthy roof in this environment.
Roof cleaning & moss removal in Hammonds Plains, NS
The large, private lots in Hammonds Plains are a major draw for homeowners, but the dense tree cover creates a significant challenge for your roof. Constant shade and fallen debris trap moisture against your shingles, creating a “nursery” for thick moss and hardy lichen. These aren’t just cosmetic issues; they are biological organisms that can lift shingles and cause rot. We provide a professional soft-wash treatment that neutralizes growth at the source, preserving the life of your roof in one of the HRM’s most wooded communities.
Our treatment includes a complimentary gutter cleaning and is backed by a 2-year limited warranty.
Why roofs grow moss in Hammonds Plains
Roofs in HRM and Hammonds Plains neighbourhoods like Kingswood, Voyageur Lakes, White Hills, Pockwock, and Cedarwood are prone to moss due to the area’s wooded lots and shaded landscapes. Frequent rainfall, high humidity, and lingering fog create consistently damp conditions, while roofs shaded by trees or located on north-facing slopes stay wet longer, providing ideal conditions for moss to thrive.
These same damp, shaded conditions that encourage moss on roofs can also affect other parts of your home, including house siding, decks, and walkways. Moisture and limited sunlight create ideal conditions for algae, mildew, and moss to grow, which is why professional cleaning and preventative treatments help protect your entire home exterior.

Common roof problems we treat in Hammonds Plains
(Algae, Moss, Lichen)
Black streaks on roofs
This isn’t dirt or mold. It is a living, blue-green algae that travels on the wind and feeds on the limestone in asphalt shingles. In areas with dense trees and shaded, moisture-retaining roofs, the algae thrives. As it spreads, it creates dark streaks that gradually weaken shingles, making them brittle and shortening the roof’s lifespan.
Moss growth on roof shingles
Moss growth is very common on roofs in wooded and damp areas in Glen Arbour, Voyageur Lakes, Cedarwood, and White Hills, where shade and moisture allow it to spread easily. This pillowy plant works its way under shingle edges as it spreads. It can grow between overlapping shingles, curling them up and allowing water to seep underneath, gradually weakening the roof over time.
Lichen patches on shingles
Unlike moss or algae, lichen is a symbiotic organism (a combination of fungus & algae) that attaches to shingles, often in shady or damp areas. Lichen creates acid to form hard, crusty patches and uses its roots to feed on limestone in asphalt shingles. As it grows, it weakens the shingles, leading to leaks, rot, and structural damage.

Hammonds Plains roof cleaning FAQs
How often should I have my roof cleaned?
Roof cleaning in Hammonds Plains 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
How much does it cost to have your roof cleaned in Hammonds Plains?

- 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.
