Asphalt shingles are among the most common roofing materials in the country. Their popularity among homeowners is undeniable. That being said, they are susceptible to the same issues as other materials, especially when subjected to extreme weather.
Damaged asphalt shingles remain a controversial subject in the roofing industry. Many of the problems with asphalt shingles are usually attributed to strong winds.
Wind Damage on an Asphalt Shingle Is Not Always Visible
Any sealed shingle damaged by the wind will leave evidence of the event. Creases, folds, tears, missing parts or any combination of these signs appear. Furthermore, this evidence is visible under careful scrutiny. A shingle that is not adhered is by itself not evidence of wind damage. It has to be creased, folded, torn or missing to prove wind damage.
A Shingle With Poor Adhesion Is Wind-damaged
Many people in the roofing industry imply that any shingle with inadequate adhesion is “wind-damaged.” This suggestion ignores the many other reasons why shingle adhesives fail. They include manufacturing inconsistencies, improper installation and deterioration. You must also consider installation in cold weather and the contamination of the adhesive. Cyclic thermal expansion and contraction are also factors that speed up deterioration.
Empirical Tests Can Show Shingle Deterioration After a Storm
ASTM and ICC have adopted wind ratings for asphalt composition shingles that range up to 150 miles per hour. Still, wind-related issues remain, as mentioned earlier. Many factors affect the sealing quality of shingles in the field. They include roof slope and interference by misplaced fasteners. It is not the target of the ASTM test methods to address such issues.
