What the Hail is Going on with a Metal Roof?
When the Storms Come, are You Protected?
Montana gets some pretty wild storms. This time of year, it’s not if we will get a hail storm, but rather when we get one. And that storm season has started already, and it is proving to be a bad one.
Just a few days ago, a storm dropped golf ball sized hail on small towns west of Billings. It was an odd storm, because the hail fell at 1 in the morning. And then yesterday, on May 20th, a storm struck the Miles City area only a couple hours east of Billings. This storm pummeled the land with hail up to the size of a tennis ball.
When these things happen, will your roof be able to handle it?
When Hail Hits Asphalt Shingles
Hail occurs when warm updrafts push the rain back into the sky causing it to freeze. Often these updrafts are weak and the hail doesn’t get much bigger than a pea. But strong storms cause strong updrafts, and the hail builds on itself getting larger and larger.
By the time it’s about the size of a quarter, it will have significant impact on an asphalt shingle roof. Hail damage from this size hail can be difficult to spot and a trained inspector should look the roof over.
When it gets bigger, about 1 to 2 inches in diameter, it will significantly damage the roof. The hail can blow out the back of the shingle causing water to find its way through.
Greater than 2 inches will always damage a roof. Shingles can even be torn loose from the top of the house.
Any time there is a storm that drops quarter sized, or larger, hail stones on the top of a house, the roof will likely need to be replaced. Even one that was replaced just a year ago will need torn off and redone.
When Hail Hits Standing Seam Metal Roofing
Here at Beartooth Metal Roofing, we specialize in standing seam metal. Metal roofing is tougher than shingles, and can obviously withstand more of an impact than its asphalt counterpart.
Quarter sized hail will have minimum impact. In fact, they may not even dent the metal at all. When you look at the roof after the storm, you will notice that it’s difficult, if not impossible, to find any dents on your metal roof.
1 to 2 inch hail is big enough to put some dings in your standing seam metal roof. However, the dents will be minor and they will almost certainly be cosmetic blemishes. The integrity of the roof won’t be damaged, and you won’t be susceptible to water leaks.
2 inch or larger hail is going to put significant dents in a metal roof. These dents will be unsightly, and you will likely want to have the roof replaced. But you won’t have to rush to have it replaced the way you would an asphalt roof. Metal is malleable, and can still maintain its function if dented. If the hail was large enough to crack or puncture the metal, then you need to take immediate steps to fix it.
It’s important to look the roof over after every storm. While metal will hold up better than asphalt shingles, it can still be damaged. This isn’t a guarantee that your roof won’t sustain any damage, but the most likely outcome.
