    Taking care of roofing is a tall order, in every sense of the word. Keeping both feet on the ground is the safer option but clutter and debris wont remove itself. Ignoring these problem areas can only mean damage and costly repairs over time. Instead of struggling to stay on your feet or navigating a careful climb – hand this job over to a Gorilla. Our team of specialists are expertly trained and outfitted to handle your Markham roof cleaning and moss removal. Let the professionals take care of the risk while you are left with the reward!

    What Makes Markham Roof Cleaning Services Vital?

    All across North America, nature runs rampant – as it should! There is nothing better than taking a walk in the woods or swimming in a lake. Plant life is great out in the opened but when it comes to city living, it can be a serious setback for any property maintenance program. With each change of season, heavy rain or wind storm, pieces of organic debris are left to fall onto the surface of your roof. It is true that having your home littered with sticks and leaves can drag down curb appeal but it also means moss, algae and lichens.

    Organics are designed to hold onto moisture. This is great while they are attached but when sitting against shingles, this can spell disaster. Invasive growth thrives in damp environments and your roof is no different. Once moss takes hold, there is no stopping it. This invasive growth will weave under and over shingling, softening sensitive materials underneath. Not only does this make way for repair costs and early replacements but it makes roof cleaning all the more difficult. Slippery surfaces make the cleaning process even more dangerous than it already is. This is where professional eavestrough cleaning comes in handy.

    The Gorilla Method

    There are certain tasks that are better left to the professionals. In the right hands, proper gutter cleaning, pressure washing and window cleaning can prolong the lifespan of your property in the same way that roof clearing can protect your home. Roofing services are designed to take care of your home’s greatest defence. Instead of just pushing organics from one place to another, our Gorilla specialists have a multi-step program for making your surfaces look their best. Any outdoor cleaning company can show up and scrape off moss. The tricky part is getting it done properly. When you call a Gorilla, any sitting debris is removed, bagged, and taken to proper care facilities to be recycled or composted. Once this is out of the way, a more clear view of moss growth (if any) is made possible. Protecting the life of your roofing begins with gentle removal. In addition to the fixtures themselves, there are other things to worry about at those heights. You might call it an eavestrough, gutter or perimeter drain but these systems are easily damaged without the right care. After years in the industry, our Gorillas know how to get the job done efficiently, safely and with excellent results.

    Common questions

    Roof Cleaning — answered

    Do you clean shed or outbuilding roofs?

    It is worth including them. Sheds and gazebos sit lower and often under tree cover, so they grow moss and algae faster than the house roof. Cleaning them alongside the main roof costs little extra because the crew and chemistry are already on-site.

    Will soft washing hurt my shingles?

    No, when properly applied soft washing actually protects your shingles. The chemistry does not dissolve asphalt or strip the protective granules; it targets the organic growth and nothing else. Pressure washing is what damages shingles, which is exactly why we never use it.

    Do you clean roofs on rental properties?

    Yes. We clean rental-property roofs across Markham for landlords and property managers as standard work. Soft-wash cleaning often slots into an annual or biennial maintenance plan, protecting the roof between tenancies without high-pressure damage.

    What about debris that washes off?

    Most debris that washes off the roof is caught in the gutters and downspouts, and our crews check that those can handle the flow before rinsing. Some material does end up at the downspout exits, and cleaning that up is included as part of the visit.

    Why does roof cleaning cost what it does?

    A roof cleaning is not just spraying and rinsing. The cost covers soft-wash chemistry, low-pressure equipment, fall-protection gear, crew training, and time on a pitched surface. When a quote looks too cheap to include all of that, it usually is, and the corners get cut on safety or chemistry.

    Do you offer roof sealing services?

    We do not apply roof sealants ourselves. That is specialized work, and forcing a coating onto a roof that still needs cleaning can trap moss and algae underneath. We handle the soft-wash cleaning first, then refer a sealing contractor if you want one.

    Can solar panels be cleaned in the same visit?

    Markham solar customers can usually have the panels and roof done together. We handle the moss and algae soft-wash on the surrounding roof, then give the array its own gentle clean in the same visit when access allows. Flag solar when you book.

    What if my roof has soft spots?

    Soft spots usually indicate structural decay underneath, often where moss has trapped moisture against the decking. If we find them, we flag the area and hold off on further cleaning there, because cleaning a weakened section can make the damage worse. Repair should come before more cleaning.

    Can you clean satellite dishes on my roof?

    In Markham, satellite dishes get careful cleaning attention. They hold sensitive electronics and an aim that is easy to disturb, so our crews use gentle, low-pressure technique around them while soft-washing the surrounding roof.
