Different roofing problems are misattributed to wind damage. This makes the topic of wind-lifted shingles controversial in the industry.
In this post, one of your leading roofing companies, Expert Contracting, discusses common misconceptions about asphalt shingle wind damage.
MYTH 1: Wind-Lifted or Wind-Damaged Shingles Aren’t Noticeable
High winds can cause shingles to flutter, bend, and develop creases. Over time, strong winds cause shingle sections to break off and get carried downwind. This is more noticeable on areas that are susceptible to higher wind forces such as the eaves, ridges, and hips. Failure commonly takes place at the top of the exposed area, below the butt end of the overlying shingle.
Wind-damaged shingles are likely to have a combination of creases, folds, tears, and missing portions. Shingles that are just not adhered and don’t manifest any of the said signs aren’t damaged by winds.
It’s important to fix small roof problems before they become bigger. At Expert Contracting, we offer quality roof repair services so your home stays protected against harsh weather and natural elements.
MYTH 2: Shingles With Insufficient Adhesion Is Wind-Damaged
Different reasons can cause shingle adhesives to fail even without the presence of strong winds. Poorly adhered shingles can be lifted and carried by the wind but poor shingle adhesion isn’t always caused by wind. Manufacturing defects, faulty installation, aging, cold weather installation, adhesive contamination, and thermal cycling can all affect a shingle’s adhesion.
MYTH 3: Empirical Tests Can Easily Determine a Shingle’s Strength Reduction
The ASTM D7158 or Standard Test Method for Wind Resistance of Asphalt Shingles is referred to by some as a proper and simple way to identify a shingle’s strength following a weather event. It aims to compare the field-measured strengths to the manufacturer’s ratings.
The uplift forces must be calculated using results from an independent laboratory. However, laboratories that are capable of performing ASTM D7158 aren’t easily accessible and may be costly. Instead of performing ASTM D7158, some choose to calculate the intended uplift forces through different methods. Keep in mind that there can be a huge difference between results using ASTM D7158 and other tools.
