It is the roof that primarily protects homes from weather elements like strong, high winds. However, not a lot of homeowners realize that high wind pressure can significantly damage their roofs and cause leaks, cracked or missing shingles and gutter problems. But there are still plenty of misconceptions about wind damage.
Shingles With Insufficient Adhesion Are Wind-Damaged
There are a few possible reasons why shingle adhesive fails. Some examples are manufacturing deficiencies, improper installation, aging and thermal cycling. Not all poorly adhered shingles are caused by wind. However, strong winds can easily lift and tear off shingles with inadequate adhesion.
Wind-Damaged Shingles Are Not Always Visible
Heavy and sustained winds can cause the shingles to flutter and bend. This leads to the formation of creases. If the wind is strong enough, it can break off shingle sections, which are then carried in the direction that the wind is blowing. This phenomenon is common in areas that are susceptible to high winds, such as the eaves, hips and ridges.
A residential roofing system affected by wind will likely show signs of damage like creases, folds, tears and missing shingles. Make sure to choose a reliable roofer in order to properly assess the condition of your roof and timely repair issues to prevent bigger damage.
Empirical Tests Accurately Indicate Reduced Shingle Strength After a Storm
The Standard Test Method for Wind Resistance of Asphalt Shingles or the ASTM D7158 is referred to as a proper method to test a shingle’s strength after a storm event. It aims to compare field-measured strength to the rating originally determined by the manufacturing company.
Uplift forces are calculated using test results from an independent laboratory. However, laboratories that are capable of ASTM D7158 testing are rare and often expensive. This causes some people to use other inaccurate and improper methods to determine uplift forces. One thing you can do is consult a reputable roofing company for proper storm damage assessment.
