How would I know if my roof needs to be cleaned?

Being a homeowner, it's important to be mindful of your home, it's integrity, upkeep and basic maintenance. Scheduling regular roof cleaning and de-mossing is a preventative measure you should not skip! 

With all the lower mainland rainfall, climate plays a big role in the lifespan of your roof. The climate here is a prefect backdrop for algae that grows on your roof - which, is not at all good for your home exterior. 


Causes of Algae, Moss, & Lichen Growth
The primary factors for organic growth are:

• Moisture:  it's consistently present on your roof. When moss begins to grow, the roof will hold even more moisture and growth will be accelerated.
• Sunlight: the percentage of sunlight each particular area of the roof receives determines how long moisture will be retained after any Lower Mainland rainfall. Roofs facing north and properties which are heavily wooded will receive significantly more shade thus resulting in more unwanted organic growth. When trees are near your roof, they provide shade needed for moss growth and spores can quickly spread to your roof. 
• Leaves, pine needles and branches hold moisture on your roof. Having excessive roof debris buildup creates a playground for roof moss to grow.

How to know if your roof needs to be cleaned
