When you're choosing a new metal roof for your commercial structure, one of the options your roofing company may offer you is heat-welded seams. These are seams that are formed by welding together solidly rather than being attached together with rivets or an adhesive. While you may pay a bit more for heat-welded seams than for these other options, they are almost always the best choice for your commercial roof. Here are four reasons why:

Increased Longevity

When roofs experience wear, that wear usually starts along the seams. Welded seams are better able to stand up to changes in temperature, exposure to high temperatures, driven rain, and high winds than other types of seams. So, it will take longer for the wear to start setting in—and you may get a few more years out of your roof.

Greater Energy Efficiency

The seams created with rivets and with some adhesives are not always airtight. You may lose some heat through the seams, causing your energy bills to go up. With welded seams, your roof essentially becomes one large, consistent piece of metal. You'll experience less heat loss and your heating bills will go down in the winter. Even in the summer, less heat will leech into the building, so your AC unit won't have to work as hard.

Fewer Leaks

When a roof is brand new, the seams are generally pretty secure, whether they're welded, riveted, or attached with an adhesive. However, as the roof ages, seams that are attached with rivets or adhesives may start to corrode. Areas may lift up, allowing water to seep between the panels and eventually leak into your business. Welded seams don't tend to have this issue; you won't have to worry about leaks.

Easier Repairs

If a terrible storm or hurricane does blow through and damage your roof, it will be rather easy for your roofing contractor to repair any damaged seams with welding. They can just melt more metal on top of the existing structure without having to first adjust and smooth everything out like they may have to do with other types of seams.

Welding forms a sturdy bond between any two metal objects. It essentially joins them to make them one consistent piece of metal. This stands true for metal roofing panels, too.
