We've been in the business of delivering award-winning roof moss removal & treatment service for several years now and I'm always surprised at how many different answers customers get from different companies. So is there a best time of year? When is the best time to clean your roof? Let's answer these questions and try to clear up some myths and misconceptions about roof moss removal.

Spring typically signals the start of the roof moss removal season. Warmer weather and fewer rainy days means that this is the perfect time to get your service done. However, the official start isn't a fixed date. Each year, rain and weather plays a role in finding ideal scheduling for your service. 

Summer is the best time of year to get roof moss removal and treatment service done on your home or business. Hot, dry weather makes the moss crumble away easily which translates to better roof preservation overall. Summer is also the busiest season, so be sure to book early if at all possible.

Fall on Vancouver Island is typically still quite hot and dry, so roof moss removal and treatment is still ideal during most of the fall season. However, like spring, we can sometimes see unpredictable wet weather towards the last few weeks. If fall is approaching, get on top of booking your service ASAP. If you've identified a moss problem on your roof you can guarantee it will get worse over the wet winter months.

Winter is a very difficult season to book service. Typically during early winter we focus on getting customers gutters ready for the rain and wet. We wouldn't recommend booking a roof moss removal mid-winter, as the growth tends to be quite vigorous during this time. Removal during winter adds undue stress and wear to your roof and becomes quite difficult to reliably schedule. MossAway has an official off-season each year, where we rest up and ready ourselves for another busy spring, but you can always find someone out there, happy to make a buck, who might do work during the off season.

In the end, it's all about finding a business you can trust. MossAway takes great care to abide by WorkSafeBC regulations and our service has earned us quite the positive reputation throughout Greater Victoria.

This is a more complicated question than most homeowners realize. There are many factors that go into a roof moss quote including:

• moss effected area of roof (physical removal area)
• total roof moss treatment area (inhibitor area)
• pitch (steepness) of roof surface
• age and condition of roofing material
• overall height and complexity of roof area
• requirements for fall arrest safety anchoring
• moss removal process or method

​
There are many different processes or methods for removing moss from a roof surface. MossAway uses the process that we feel is the safest and most effective which we call the "Brush & Treat" method. Hand brush removal of the moss is labour intensive but the quality of removal is extremely high compared to any power form of physical removal. It is also considerably safer for your roof than other removal methods. We would never recommend that a homeowner allow a contractor to pressure wash or "soft wash" your asphalt shingles. We have plenty of photos of severely damaged rooftops that were pressure washed - stay tuned for that post later in the month.

MossAway has an average service cost of just $750 across all services conducted in 2018 with invoices ranging from just $350 to just over $2500. [Edit: June 2022] It's important to note that the global pandemic, rising fuel prices, and supply chain issues have dramatically increased costs since this post. In 2022, the average quote is currently closer to $1150, with the largest residential projects typically hovering around $3500. Since this post in 2018, we have also implemented the moss-free membership. Customers booking roof moss removal & treatment projects with MossAway are treated to free yearly reviews of their roof. MossAway catches moss growth early, aiming to spot-treat for around $150-250, only if you need it, every 2 - 4 years. This should greatly increase the longevity of our service and the lifespan of your roof. See our more recent articles for more details. [End of edit]

Are there even more affordable methods? This is quite reasonably the most affordable process possible to safely & effectively remove moss from an asphalt rooftop. Every so often a customer sends us a lower competitor quote, and almost every lower quote we've received was from a "guy with a truck and ladder" outfit. Do keep in mind - our industry sees some of the highest WCB rates of any industry, quality workers for this time of work do not come cheap, and if you employ someone who is not covered by WCB and/or doesn't carry liability insurance you could be in for quite the unpleasant experience. For more on that, check out our post about why WorkSafe coverage is so important when selecting a contractor, coming out later this month.

The best time in Victoria to remove moss from your roof is mid-March until late May. June and July are also good months to remove moss however by late spring to early summer moss has started to seed and spread to other areas of your property that might later become a nuisance.

We do not recommend removing moss in December, January, or February. In our climate, moss is full of life and quite difficult to remove mid-winter. If rains are bringing vigorous growth to your mossy roof the best thing you can do is wait until drier weather when the moss can be brushed away with relative ease.

Moss treatment can be conducted at almost any time of year. As you might suspect, a spray treatment should be done during an absence of wet weather so as to increase the overall efficacy of the treatment.
