Winter has been unusual and the roof and gutter system has taken a LOT of extra weight of snow and water, let alone tree debris like branches, leaves, seeds, fluff, and so on. 

The system needs to be checked to make sure the gutters are still attached to the facia board.  That extra weight through our snowy winter could easily have detached the gutter.  If this happens, the gutter will develop a low area where water will pool.  This will cause more droop of the gutter, and more water to collect.

Vancouver and Richmond houses are under attack 24/7 by forces we have little control over, but must cope with to keep the value of our homes at their highest level.

 

The facts of being on the ocean, under a cloudy sky most of the year, within a forest and at the 49th Parallel all contribute to the changes we see in our houses and our neighbor's houses.

 

What is the black and green coloration that appears on all the concrete, walls, roof, chimneys, patios, walkways, driveways, and bricks?
