Common Roofing Problems
Email To Friend | share this article | Posted by Dean on February 1st in Roofing.
Hopefully it doesn’t take a leak to motivate you to inspect your roof and look for potential problems. We have created the following guide to help you identify problems with your roof and what you should do about it. Be advised, this resource only provides examples of asphalt shingles.
The following will help you identify the potential for roof failure. Check your roof for these characteristics regularly, and don’t wait to take action!
Buckling
Buckling is a visible distortion or waviness in the horizontal lines of shingles, and usually runs in a straight line up the roof slope. Shingle tabs become exposed to wind and can be torn off. Very often, the problem is warping in the roof deck caused by poor attic ventilation. The use of thinner-than-recommended plywood and other non-plywood materials adds to the problem.
Flashing
Many problems occur at the flashings around vents, soil stacks, chimneys and vertical wall joints. Is the flashing cracked? Is the caulking around the flashing dried out? Are the shingles that lie over the flashing in good shape?
Bare Spots
The protective granular surface of shingles wears off as the asphalt, into which the granules are embedded, begins to harden over time. Bare spots are often accompanied by fine fissures on the shingles’ surface and by the accumulation of granules in the gutters.
Curling
The upward curling of shingle tabs makes them highly susceptible to wind and ice damage. This is a problem on older roofs where moisture build-up in the attic affects the underside of the shingle.
Broken Shingles
Damage can be caused by extreme wind conditions and snow removal. Since shingles are supposed to shed water, broken, torn or missing tabs become obvious entry points for water, especially on low slope roofs where run-off is slower and at the peaks of the roof where shingles are the most vulnerable to high winds.
Clawing
This is the curling under of the shingle tab’s bottom edge and is part of the normal aging process of shingles. The bulge created is susceptible to substantial damage by wind action, hail and ice.
