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.
BROKEN SHINGLES – Damage can be caused by extreme wind conditions. Since shingles are supposed to shed water, broken, torn or missing tabs become 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.
