In Winnipeg, our roofs endure harsh winters and humid summers, creating the perfect environment for moss, algae (Gloeocapsa magma), and lichen to thrive. If left untreated, these organisms eat away at your shingles, leading to leaks and voiding insurance policies.
At Simba Management, we believe in transparency. Instead of waiting days for a quote, use our tool above to get a highly accurate estimate in seconds.
The average cost for professional roof cleaning in Winnipeg typically ranges from $0.25 to $0.45 per square foot. For a standard 2,000 sq. ft. home, homeowners can expect to pay between $400 and $800. Factors affecting the final price include the steepness of the roof, the type of material (asphalt vs. tile), and the severity of moss or algae growth.
Our calculator uses real-time local data from the Manitoba market. Here is what drives the cost of your quote:
We do not use high-pressure power washers on roofs. High pressure strips the granules off your shingles, shortening their life. We use a Soft Wash system—a low-pressure application of eco-friendly algaecides that kills spores at the root without damaging your home.
Most homes in Winnipeg require cleaning every 3 to 5 years. However, if your home is surrounded by trees or faces north (where moisture lingers), you may need treatment every 2 years to prevent moss regrowth.
No, provided it is done correctly. We use a "Soft Wash" technique that relies on chemistry, not pressure, to clean. This is the method recommended by the Asphalt Roofing Manufacturers Association (ARMA).
Insurance companies in Manitoba are increasingly sending cancellation notices to homeowners with mossy roofs. Moss holds moisture against the shingles, causing rot. Cleaning your roof is often required to keep your policy active.
Our base calculator estimates the roof treatment only. However, we highly recommend adding gutter cleaning (available as an add-on) because rinsing a roof often fills gutters with debris.
We take plant protection seriously. Our team pre-soaks all surrounding vegetation with fresh water and covers delicate plants before applying any solutions. We also rinse them thoroughly afterward.
We advise against it. Dry scraping can rip shingles. Furthermore, scraping only removes the visible moss, leaving the roots (spores) embedded. Our treatment kills the spores so the moss doesn't return immediately.
An average residential roof in Winnipeg takes between 3 to 6 hours to clean, depending on access and the severity of the debris.
Yes. Simba Management provides a "Moss-Free Guarantee" on full treatments. If organic growth returns within 12 months, we will re-treat the affected area for free.
This tool provides a highly accurate estimate based on our standard pricing. However, difficult access points or unlisted hazards may slightly alter the final official quote.
No. As long as we have access to a water spigot and the perimeter of the house, we can perform the service while you are at work. We will send you before-and-after photos once the job is done.
Don't let moss eat your investment. The price you see above is a solid estimate, but we'd love to give you a firm price and schedule your service.
