Asphalt Shingle Blow-off

Asphalt Shingle Blow-off: It’s Causes and How To Fix It

Asphalt shingles are designed to resist hurricane-level winds. In fact, most asphalt shingles manufactured today have a wind rating of 110-130 miles per hour. Still, it is not uncommon for shingles to be blown off and most homeowners are quick to call in roof repair contractors to have the problem fixed. While this is, of course, the most recommended course of action when you are missing shingles from your roof, it is also important to understand why they were blown off in the first place. 

In today’s post, trusted roofers 3JM Exteriors, Inc. explain what could be causing your shingles to be blown off and what steps you can take to address it.

1. Too Much Overhang

Asphalt shingle overhangs are not only aesthetically pleasing, they also serve clever utilitarian purposes, like providing shade for windows and eaves and even regulate temperature. Asphalt shingles, when installed correctly, should hang over the edge of the roof between 1 to 1.5 inches. Too much overhang can make them susceptible to strong winds.

2. Incorrect Nail Pattern

Most manufacturers recommend a very specific nail pattern for the proper installation of asphalt shingles. In fact, most shingles will have a narrow strip to help roof repair contractors identify where to place the nails. If this pattern isn’t followed, then this will make your shingles more prone to blow-offs.

3. Your Roof Is Approaching the End of Its Service Life

Your average asphalt shingle roof is expected to last between 15 to 25 years depending on the quality and exposure to the elements. As your asphalt shingle roof reaches the end of its lifespan, the adhesive that helps seal the shingles begins to weaken and lose its effectivity making it more likely to be blown off during a severe wind event.
