How metal roofing stands up against hurricane winds

Metal roofing has a reputation of lasting a long time. In fact, there are plenty of them covering old barns or early 20th-century homes, installed long before the latest updates and advances improved standing seam metal roofing into what it is today – and these old roofs are still going strong, well over half a century or more later! Asphalt, by comparison, rarely lasts 20 years. But where metal roofing used to lack in curb appeal, it’s now on par with other roofing materials for good looks. And nowadays when you go with standing seam metal roofing, you can expect low maintenance alongside a warranty that will average twice the age of an asphalt roof alone. As Home Advisor notes, metal roofing might seem more expensive, but it pays off in the long run, especially when you have it installed by a quality metal roof contractor.

But metal roofing does more than just last a lifetime – it offers your home the promise of security, even through the worst weather, from wildfires to hurricane force winds. Curious just how much metal roofing can stand up against? Construction Magnet has all the blustery info on how metal roofing stands up to the worst windy weather Mother Nature can provide.

How metal roofing makes a difference
The best way to install metal roofing and ensure it’s able to stand up against hurricane-force winds

is to work closely with the manufacturer. Both the materials and the installation itself should meet the code requirements for your part of the country. Miami-Dade county has notoriously stringent certification criteria and provides an excellent litmus test for just how well roofing will hold up against roaring winds.

The news source notes that many metal roofing manufacturers invest thousands of dollars into testing and certifying products. Usually, roofing products are rigorously subjected to both in​-house and third-party lab tests. This goes double for hurricane zone roofing, which is usually maximized for weather resistance. The news source explains some of the differences.

There are three main areas on a roof: the field, the main area, where there’s the least stress from wind; the perimeter, a roof’s outer edges, where wind wind uplift is a potential problem and has been known to sheer off shingles on non-metal roofs; and the corner, the spot where edges converge and wind uplift is at its worst. Since wind uplift is the primary concern, the source notes that the roof’s purlins should be grouped closer together. If they’re spaced 5 feet apart in the field section, they should be two feet or closer near the corner or perimeter where uplift is heavier.

Roofs aren’t only vulnerable to wind during hurricanes, the news source notes – they can also be damaged by what those winds carry. Flying debris can be extremely destructive, but it’s one more reason metal roofing wins over asphalt. Standing seam metal roofing can stand up to hail and driving rains or giant tree branches just as well as the flaming debris of wildfires. So homeowners with metal roofing over their heads – whether in Miami-Dade county or further up the coast – can rest easy throughout the most vicious of hurricanes and storms.
