Here in northern Nevada, we're no strangers to high winds. And after one of our famous wind storms, it's not uncommon to see branches and, you guessed, bits of wood shake and comp roofing all over the place. It's one of the many reasons we've found metal roofs to be so successful in our area - one of the most noteworthy features of metal roofs is their resistance to high winds.
So what's the secret? Why are metal roofs, like these Energy Star certified finished steel shingles, so superior when it comes to high winds?
- Unlike other roofing material choices, most metal roofs have the advantage of a fully mechanical attachment. This is opposed to other other materials like asphalt shingles that use a perpetually deteriorating adhesive to remain in place, or concrete tiles which rely mostly on their extreme weight to resist high winds. With a properly installed metal roof, a perimeter or nails, screws, or mechanical locks affix the material to the structure and this allows most metal roof manufacturers to offer wind warranties of 100MPH or more.
- Best of all, the wind warranties for the better metal roofs don’t expire and are in place for the entire length of the warranty period (usually 50 years or more). Contrast this with most asphalt shingles – even those with “100MPH” wind warranties. Too bad about that inconvenient exception: their wind warranties expire in as little as five years! Remarkable statement about the confidence the manufacturers have in those products, wouldn’t you say?
- Another bonus to wind-resistant metal roofing? You'll enjoy the other benefits inherent to this material - the same features that protect it from high winds (strength, lightweight, interlocking design) make it a fantastic choice in earthquake-prone areas. Plus, it's incredibly durable, unbeatable in terms of longevity and lifespan, eco-friendly and available in an assortment of styles, colors and finishes.
