Pine Shakes Information

This is from the Alberta Government Municipal Affairs website.

It is wise practice to have all roofs using wood shakes or shingles, including those made of untreated pine shakes, inspected by a qualified person at least annually.

If black spots or other indications of fungus appear on an untreated pine shake roof, a qualified person should inspect the roof promptly. As with other wood on or in a building, if shakes become infested with fungus, this could lead to safety and health issues.
