We had Big Moose power washing clean our gutters and put up our Christmas lights. They are well priced and professional. Did a great job at both. Would definitely recommend.

Jon Marshall

Contacted them and he got back to me within about 5 minutes! Confirmed the price and time within 30 mins and then came by two days later. Would’ve been the next day if it wasn’t for the ridiculous heat! Best price I found, best response/communication, and the windows look great. Amazing job!

Our Roof Washing Process In Coquitlam

The results to expect from our roof washing service

Our roof washing and roof cleaning process consists of the same goal, which is to remove moss, treat moss, and provide a moss control plan for your roof. Roof washing should be done as soon as the first sight of moss is spotted on the roof, once you see the moss on the roof from the ground, it mostly likely means 70% of the roof has already become infested with moss, mold, algae, black streaks and mildew. 

Roof washing and roof cleaning in Coquitlam is extremely important as roofs become quickly taken over by moss, and mold. It is a snow ball affect, as the moss is left untreated it builds up more and more moss onto itself. Eventually your roof shingles begin to warp and can become permanently damaged as the moss finds itself further and further in and in between your shingles.

Removal of debris should be done periodically every year or multiple times a year, gutter cleaning in Coquitlam is very vital as well during this process, as the rain storms will cause your basement to flood if your gutters are not serviced on a routine schedule. Cleaning the big chunky moss and roof valleys full of leaves is the first step in keeping the rain from damaging your home. Gutters get clogged easily with an untreated roof full of moss and debris.

When you receive a moss treatment service for your roof you will be guaranteed at least 3 years of no moss or mold, if any signs of moss appear within that time frame we will come back free of charge to respray your roof. The roof washing and roof cleaning in Coquitlam provides some serious benefits for home owners, it prevents future and current water damage disaster from occurring.

Roof Cleaning

Replacing a roof can be a costly expense that everyone tries to avoid. How can you extend the life of your roof and avoid replacing it? By having a professional wash it for you. The best approach to extending the life of your roof is to clean it when it becomes unsightly. Roof washing is a commonly overlooked service as organic growth builds up over time and homeowners slowly get used to the look - however, this can cause serious problems. Having a clean roof goes beyond being an aesthetic service because structural components of your home become affected when there is organic debris flourishing on your home. We often get calls from homeowners that they need to get a roof cleaned either because their insurance policy is going to get cancelled or they are about to lose warranty coverage. ​

Trust the Process

At Big Moose Powerwashing Inc. we are certified in our craft. Our technicians use the soft wash approach to eliminate any organic growth on your roof. Typically, the first sign of life on your roof begins with mysterious black streaks that begin to appear. This is known as “Gloeocapsa Magma,” and it is a type of bacteria that feeds off of the limestone on shingles. Once this organic growth has made a foothold on your roof, moss, lichen, and mildew begin to grow as well. While the quickest way to get rid of this may be to directly powerwash the roof, the cost in damage outweighs the benefits. Using high pressure to remove any organic growth on a roof can lead to granules & shingles being dislodged, water getting behind sealing, and a huge mess. Powerwashing also only removes the top layer of growth, and doesn't fully resolve the issue as organic materials will start growing again in the matter of a few weeks. In contrast, the soft wash approach allows us to strategically eliminate anything alive that's feeding off of the shingles. We personally guarantee that nothing will come back for a minimum of three years time

Types of Roofs We Clean

There are many different types of roofs that organic growth will flourish on. We are fully equipped with the technology (and safety equipment) to tackle asphalt shingle, tile, metal, slate, and aluminum.
