Roof Cleaning Services: Boost Curb Appeal & Prevent Damage

You don’t have to hit those heights to see that your roof is in rough shape. Even from the ground level, it is possible to see clutter collecting against surfaces. Depending on the style of plant life around your home, commercial property or multi-unit space, roofs can quickly become cluttered up with leaves, twigs, needles, seed pods, pinecones and other items.

When a roofing system becomes covered in debris, it does not only look terrible but it can lead to moss growth. Even a bit of moss can grow rapidly, weaving itself over and around shingling, reaching down to the sensitive decking underneath. As moss begins to take over, it softens vulnerable materials, causing damage.

Hiring a roofing contractor in Halton Hills to have roofs installed is great but what happens to these fixtures afterward? Not all roofs are built the same way. From flat roofing to peaked styles, asphalt shingling, concrete roofing, aluminum finishes and beyond, these are complicated areas – so leave their care to the professionals.

Seeking Out Quality Roof Care

In order to get the best results for our clients, Gorilla crews have broken roof care into an accessible, multi-step approach. First clutter is removed and any moss growth is addressed. Instead of trying to tackle these problem areas with the wrong tools like wire brushes or dangerous soft washing, our experts cater our approach to your space.

Roof projects are a complicated business. It is always a question as to whether or not to leave your structures in the care of a large company or a family owned and operated business. Locally owned companies offer a distinct advantage in both customer service, results and access.

There are plenty of ways to upgrade your roofing but they do not always need to be full replacements or skylight installation. Routine maintenance is a way to improve the look and condition of your structure without a high price tag or unnecessary risk. Call our team of experienced Gorillas today for you free estimate.

Roof Cleaning — answered

Do you handle flat commercial roofs?

For Halton Hills flat commercial roofs, we service all common types: TPO, PVC, and EPDM membranes, built-up roofing, and modified bitumen. Low-pressure soft washing keeps seams and surfaces intact while clearing organic growth and accumulated buildup.

What's included in a standard roof cleaning?

For Halton Hills properties, a standard roof cleaning covers inspection, soft-wash chemistry across the affected areas, dwell time, and a gentle rinse, with gutter coordination so debris flows away properly. Low pressure throughout protects the shingles.

Is soft washing safe for older roofs?

Older roofs are precisely where method matters most. Aged shingles are more brittle and have already lost some granules, so high pressure can finish them off. Soft washing applies no such force, cleaning the surface gently while leaving fragile, weathered materials undisturbed.

Will roof cleaning extend the life of my roof?

Yes, significantly. Moss and algae actively shorten roof life by holding moisture against shingles and lifting them over time. Removing the growth and treating to prevent regrowth stops that damage and restores the roof’s expected service life. It’s one of the main reasons to clean, beyond appearance.

Do you clear roof drains?

Yes. Clearing roof drains and scuppers is a standard part of our flat roof service, not an add-on. Open drains are critical for water flow, since a single blocked drain can hold inches of water across the roof and overload the membrane.

Will the chemistry smell?

For Halton Hills customers, there is a mild chlorine smell during application that dissipates within hours as the roof dries. It is most noticeable while crews are on site, so some homeowners book the job for a day they will be out.

Why does soft washing work better than pressure washing?

It comes down to root versus surface. Pressure tears off what you can see but leaves the living organism behind to regrow, and it damages the roof doing so. Soft-wash chemistry kills the moss and algae outright, so the clean lasts and the roof stays safe.

Will roof cleaning brighten my home's appearance?

Yes, though the brightening comes from restoring the shingle’s surface, not bleaching it. Algae and moss form a dark film that absorbs light and dulls the roof. Lifting that film lets the original tone show and reflect daylight, which freshens the home’s overall look.

Will my home be cooler after cleaning?

Slightly. A clean roof reflects more sunlight than a dark, algae-covered one, so less heat transfers into the attic and living space. The change in indoor temperature is modest and most noticeable in hot-climate homes with limited attic insulation.

"We had Darcy and Cosmo from Halton do our gutters and clean the exterior of the gutters. I was amazed at the end result!!! My husband said “nobody can clean that” but Darcy proved him wrong! We are so happy with the job they did today, cleaned the gutters, soft washed the exterior, and because all the dirt started running down the siding…..they cleaned that also. My exterior looks like a new house now!! And they did it all with a smile! Darcy is very knowledgeable about what he is doing, explained anything that we needed, his communication is spot on. Also, as most of us know, in todays world, it’s hard to find honest help, and there are time when I have been taken advantage of. BUT! I have to say that Darcy does as Darcy says, and if you don’t need it, he is not going to make you think you do. I will be doing everything I can to let people know what fantastic people Darcy and his team is, but first and foremost, what an excellent job he did for us today. Below are the before and after photos from today, you can see how black the exterior gutters were…….then Darcy and Cosmo showed up with their magic and look at the end result…..OUTSTANDING!!!"

"We had some construction being done at our house and as a result our windows became very dusty. I had reached out to Darcy to see if he could hook us up with some window cleaning.... I've gotta say, working with Darcy and his crew was a real treat. Darcy seems to be big on communication ensuring our 'project' was attended to within our scheduling timeline and at the end of our window cleaning wanted to ensure we were satisfied with the service his company had provided. His crew was efficient, respectful, polite and did an amazing job. I have come to learn that Gorilla Property Services provides a myriad of home based maintenance services that we will enjoy exploring in the near future. Thanks Darcy for being so Awesome!!!"

Nancy WHITTEKER

"Excellent service! I have never seen our windows look so clean — they are absolutely sparkling, and even my husband noticed the difference right away. They arrived on time, completed the job in a very reasonable amount of time, and the pricing was fair compared to other companies we’ve used in the past. Very happy with the results and would definitely recommend them."

"I had an excellent experience with Darcy Blais from Gorilla Property Maintenance in Georgetown. He provided both dryer vent cleaning and window cleaning services, and from start to finish, everything was handled with professionalism and care. Darcy was incredibly organized and prompt, arriving exactly when scheduled and ready to go. He was courteous throughout the entire visit and took extra care in my home—something I truly appreciated, especially when he put on shoe covers to ensure everything stayed clean. What really stood out was his attention to detail and communication. Darcy clearly explained what he discovered during the service, walked me through the work he completed, and provided helpful guidance on how to properly maintain my appliances moving forward. That level of transparency and education is rare and very valuable. I wouldn’t hesitate to recommend Darcy to anyone looking for reliable, high-quality service. If you need dryer vent or window cleaning, you’ll be in great hands!"

"Darcy, from Gorilla Property Services, took time out of his Saturday morning to make sure that our dryer vent cleaning job got done, after the rainy weather kept him grounded all week. Excellent service and communication. He took time to explain the job and what was done, making sure that it was done right, not just "done". I'd highly recommend him for your next property maintenance job."

Carolyn Callero

"Highly recommend Gorilla Property Services! They cleaned out my eavestroughs, cleaned all of my interior and exterior windows, and removed the mold around my windows as well. Everything looks absolutely amazing now! The team was very professional, on time, efficient, and paid great attention to detail. It’s hard to find companies that truly care about the quality of their work, and these guys definitely do. Very impressed with the results and would absolutely use them again!"
