Roof Cleaning & Moss Removal in Winnipeg
At a Glance
- Who: 204 Pressure Washing.
- What: Safe, low-pressure roof restoration, moss removal, and black streak eradication.
- Where: Serving homeowners across Winnipeg, specifically targeting heavy-canopy neighborhoods like River Heights and Linden Woods.
- The Bottom Line: We use a 60 PSI soft wash system to kill moss and Gloeocapsa Magma at the root. This prevents destructive ice dams and shingle lift caused by Winnipeg’s freeze-thaw cycles, without blasting away your protective UV granules.
Protect Your Roof from Winnipeg Winters
Your roof is the first line of defense against our harsh Manitoba climate. In Winnipeg, the weather swings from scorching, humid summers to deep-freeze winters. This cycle creates the perfect storm for roof damage if organic growth is left unchecked.
Moss and algae are not just cosmetic issues; they are parasites eating your roof. Moss acts like a sponge, soaking up moisture from rain and melting snow. With Winnipeg averaging over 100 freeze-thaw cycles annually, that trapped water turns to ice.
- The Threat of Shingle Lift: This expanding ice lifts the shingles up from the deck. Once a shingle is lifted, it catches the wind during brutal prairie gusts, leading to tear-offs and severe leaks.
- The Threat of Ice Dams: Thick moss prevents water from draining properly into your gutters. This creates massive ice dams on your eaves that force water backward and straight into your interior walls.
204 Pressure Washing stops this cycle. We remove the growth, restore proper drainage, and prevent ice dams to extend the lifespan of your roofing materials.
The Soft Wash Solution: Safe & Effective
Many homeowners—and even some inexperienced contractors—make the disastrous mistake of using high-pressure wands on a roof. A standard pressure washer causes premature granular loss, forcefully blasting away the protective granules on your asphalt shingles. Those granules are there to protect the asphalt from UV rays. Once they are gone, your roof ages rapidly, dries out, and cracks.
We use a Low-Pressure Soft Wash method.
Instead of relying on force, we use a specialized, biodegradable surfactant solution. This chemistry dwells on the surface and seeps deep into the root system of the moss and lichen, neutralizing the infestation at the source. The pressure we use is roughly 60 PSI—the exact same as a garden hose. It is enough to rinse the roof clean but gentle enough to keep every single granule in place.
Eliminating Black Streaks (Gloeocapsa Magma)
Have you noticed ugly black streaks running down your roof, especially on the north-facing side? That isn't dirt. It is a highly destructive bacteria called Gloeocapsa Magma.
This bacteria actively feeds on the limestone filler used in modern asphalt shingles. As it eats the limestone, it weakens the structural integrity of the shingle and destroys its ability to reflect heat, which spikes your cooling bills in the summer. Our soft wash process kills this bacteria instantly, restoring your roof to its original color and stopping the decay in its tracks.
Local Expertise: River Heights, Linden Woods & Beyond
We know the local landscape. Neighborhoods like River Heights and Linden Woods are beautiful because of their mature tree canopies. However, that heavy shade—combined with proximity to areas like the Assiniboine Forest—creates a massive breeding ground for moss and fungi.
The lack of direct sunlight allows moisture to linger on the roof and accelerate growth. If you live near Route 90 or in the older, tree-lined streets of the city, your home is at a much higher risk. We assess the exact level of shade and the type of foliage surrounding your home to determine the precise strength of the treatment needed for your property.

Frequently Asked Questions
Do black streaks affect heat retention in winter?
Yes, the black streaks are Gloeocapsa Magma, a bacteria that darkens the roof. This dark color absorbs more UV radiation, heating up your attic in summer and preventing proper snow shed patterns in winter.
Do you use pressure washers on asphalt shingles?
No, never. Pressure washers will blast away the protective ceramic granules that shield the asphalt from the sun. Losing granules cuts the lifespan of your roof in half.
Does moss ruin shingles?
Yes, moss roots lift the leading edges of the shingles. In Winnipeg, wind-driven rain or melting snow can then get under those lifted shingles, leading to leaks and rotted decking.
Will the roof chemicals corrode my aluminum gutters?
No, we constantly flush the gutters with fresh water during the process. While the cleaning solution is corrosive if left to dry, diluting it immediately prevents any reaction with the metal.
Is the runoff safe for my pets?
Yes, once the solution hits the ground and is diluted, it breaks down into salt and water. We ensure no puddles of concentrated chemical are left behind for animals to investigate.
Does zinc stripping work immediately?
No, zinc strips rely on rain to wash metallic ions down the roof over time. Our soft wash process works instantly to kill the infestation today, rather than waiting months for a passive system to work.
Does lichen grow faster on north-facing slopes?
Yes, in the Northern Hemisphere, north-facing roofs get less sunlight and stay damp longer. This moisture allows lichen to anchor deeply into the shingle, requiring a stronger mix to detach safely.
