How does moss damage Vancouver commercial roofs?

Moss loves moisture. So Vancouver’s wet climate provides the perfect growing environment.

You know what doesn’t love moisture? Your commercial roof.

Moss on your roof is never a good sign and here’s why.

Commercial flat roofs are built to direct water off the surface into drainage systems. When water stays on the surface it starts to degrade it. As moss continues to grow it causes roofing materials to lift and pull away. Leaks become inevitable.

Your roof is out of sight. It makes it easy to forget to check for moss and deal with it. So what starts as a little problem that is quick and easy for commercial roofing services to deal with, becomes a bigger problem and a huge expense. There have been cases where inaction has resulted in the need for a total roof replacement and the loss of tens of thousands of dollars.

Blocked drainage systems don’t allow water to flow off your roof to the ground. Given the number of wind storms and trees Vancouver has, drains, gutters, scuppers can be easily overwhelmed by the amount of organic material blown onto commercial roofs. Needles, leaves, branches, twigs and other debris consistently build up over time to cause clogs.

Older roofs and roofs that are not in the best shape can have weathered areas with cracks, pooling and other damage that prevents water from draining. These little pockets and fissures of moisture allow mould to get a foothold. Since mould spreads by spores, it’s not long before it covers more and more of your roof, adding water, weight and lowering its life expectancy.

Commercial roof maintenance. Hiring professionals to get the job done right and efficiently is easy on your time, easy on your mind and easy on your pocketbook.

Ideally, commercial roof maintenance in Vancouver should be done twice a year, in spring and fall. Routine, proactive maintenance, including keeping drains free-flowing, trimming back surrounding trees, removing debris from the roof and spot-fixing damaged areas will keep your roof free from moss and extend its life.
