Coquitlam’s boundaries stretch from the Fraser River all the way up to the Pitt River. This expansive land mass also includes mountainous regions including Eagle Mountain and Burke Mountain. Like North Vancouver, Coquitlam receives more precipitation than most areas in the lower mainland. This, along with tree cover will allow moss to develop on your roof much quicker than other areas across the lower mainland.


Coquitlam is made up of several different neighbourhoods such as:

  • Maillardville             

  • Cariboo                     

  • Burquitlam              

  • Austin Heights 

  • Harbour Chines        

  • Meadowbrook           

  • Dartmoor                

  • Chineside

  • Cassin                      

  • Harbour Village        

  • Ranch Park              

  • Essondale

  • Eagle Ridge              

  • River Springs          

  • Westwood Plateau   

  • Burke Mountain



Coquitlam, as described above is quite large, and often described as a “tilted hourglass” as two large parcels of land are joined together, connected by a smaller parcel of land. Homes and neighborhoods in the south portion of Coquitlam will have varied types of roofs such as tar and gravel and tile, but most roofs are asphalt shingle. Roofs in this area receive lots of sun exposure, which helps with preventing moss growth, however if you look at the north facing sections of the roof you will notice that your shingles are likely stained, this is caused by algae. This type of algae promotes black staining or discoloration; however, it is more of an aesthetic issue versus the damage of moss growth to a shingle. An application of our moss and algae roof treatment will kill the moss and gently lift the algae that is causing those black stains on your roof. In time, mother nature will gently wash away the black stains without any damage to your roof. Our moss removal and treatment process ensure no power washing or soft washing is ever needed.


Roofs in North Coquitlam, especially homes built up on Burke or Eagle Mountain are often constructed with concrete tile roofs. This type of roofing material, along with the steep pitch of the roof can make it extremely difficult to clean and often requires multiple days to complete. Due to this, it is paramount to always treat your roof every 3 years to ensure there is no moss on your roof. If your roof has been neglected for several years, and there is heavy moss accumulation, your options will be limited and the cost for removal will be significant.


Port Moody is a small municipality situated to the east of Coquitlam, however they both share Eagle Mountain, and in doing so, many of the roofs are the same type roofing materials used in North Coquitlam. Since most of the roofs in Port Moody are tile, it is crucial to have your roof treated every 3 years to remain moss free.
