Even though the local weathermen are notoriously inaccurate, I was prompted by this morning’s “High Wind Warning” for the area to comment on one of the most noteworthy features of metal roofs: resistance to high winds.
Unlike other roofing material choices, most metal roofs have the advantage of fully mechanical attachment. This is opposed to say, asphalt roofs that use a perpetually deteriorating adhesive to remain in place, or concrete tiles which rely mostly on their sheer 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?
So if the weatherman is right this time and we are hit with roof-damaging winds again, causing yours to find its way from the roof to the ground, then I highly recommend you consider a fine metal roof as a replacement. Then you can rest well the next time the wind howls!
