One of the most frequent questions homeowners ask us is if their metal roof will be noisy when it rains and hails. And certainly given the long life-span of metal roofing (50+ years), it’s a valid concern.
The short answer is, no they aren’t any noisier than other types of roofing.
Surprised? You aren’t alone. The confusion stems from the construction of the roof. When the roof assembly (decking/insulation/underlayment) match that of a shingle roof, the noise level is no different. But it’s no wonder folks miss this small differentiator.
If you’ve ever been in a pole building or garage with a metal roof that didn’t have a plywood deck and insulation under it, you likely noticed the loud noise caused by rain and hail. In fact, rain can sound like a downpour inside the building when in actuality it’s only a light shower. Without the roof deck, insulation, and underlayment, the metal panels can actually intensify the sound. But as soon as those building components are added, noise levels return to what could be generally expected with any other roofing material.
Some metal manufacturers have created systems that allow for metal panels to be installed over the top of existing shingles. For more on our system, check this out. In these applications, the existing shingles also serve as an additional insulator and even further reduce the noise that many homeowners falsely associate with “all” metal roofing.
And of course, increasing insulation in the attic airspace provides a double benefit for both shingle and metal roofing. Adding more insulation typically results in energy savings and also keeps the interior of the home quieter.
But on the other hand, if memories of waiting out a good storm to pass in grandpa’s shed are something you want to relive, just install metal panels directly over open framing without decking, insulation, and underlayment. You’ll be able to relive those fond memories every time it rains!
