My name is Jeff Mathieson of Tartan Window Cleaning serving mid Vancouver Island.
Much of the moss removal is at the 7 to 10 year growth. Leaving it to this point takes significant greater efforts and chemical to correct resulting in higher costs.
Safety harness anchor installation, often 2 applications of chemical, and much more labour.
At the first sight of moss call us!
Your roof can be sprayed from the roof perimeter with the aid of ladders to kill the growths and removal can be achieved with sun and rain cycles.
Please visit our web site and call anytime from 9-9 if you have any further questions.
