Cedar Shake Shingles – Common Problems

• Rot might be found in this material – especially if it is exposed to prolonged periods or moisture

• Cupping can occur – where both sides of the material lift

• Cracking or splitting is a defect that can create openings in unwanted locations

• Curling – where the bottom of the shake lifts up

• Burn-through is most often found near the center of the exposed area of the shake and can expose the felt underlayment to harmful ultraviolet rays – this can accelerate deterioration and can eliminate your second line of defense against roof leaks

• Exposed felt underlayment is an area of concern and might indicate improper installation of the roof

• Missing or damaged hip or ridge shakes are commonly found defects and will leave those areas open to the weather

• Exposed fasteners found anywhere in the roof surface are leaving unprotected openings in the roof and indicate improper installation practices

We suggest an absolute minimum amount of foot traffic, only when absolutely necessary and only by people knowledgeable about how to walk on these types of roofs.
