New Metal Roof Making Noise

The noise factor associated with metal roof has a lot to do with how secure the sheets are.

New metal roof making noise. I had a new metal roof installed on battens over existing shingles. Also roofing installed with few fasteners fasteners not firm or fasteners in the wrong place tend to move when hit by rain or hail. The sun hits your roof and heats it up. The wind is flexing the rafters or trusses.

The sounds are typically only audible if you re on or near the roof or if the underside of the metal decking is exposed to finished interior space. This is a step that must be taken during the installation process. Metal roof thermal expansion is something every roofer greatly accounts for during installation. In rare cases in one particular roof assembly with standing seam panels the expansion contraction sounds can become louder inside a building.

It makes popping sounds when it heats up. When we install a metal roof there is a sheathing that goes between the metal roof and the surface of your current roof. This movement creates the popping noise. No roof is quiet but you ll find that a metal roof controls noise from.

The sun might be the one causing it. However many instances of metal roof popping noise isn t because it s raining or birds are perching on the rooftop. Popping in the morning and evening is thermal expansion. Because this style of roofing sheets is lightweight they can easily be damaged and destroyed by wind.

And the answer is no they re not noisier. Popping in the morning and evening is thermal expansion. As the lumber expands it moves and it will rub against other pieces of wood that aren t moving at the same rate. The wind is flexing the rafters or trusses.

Installing an underlayment between the metal roofing and the roof sheathing is a key step to reducing metal roof noise. If your roof is installed without a proper roof underlayment you will experience the kind of noise that causes people to think buying a metal roof is a bad idea. Roof popping noise can be caused by the wind. I have contacted the contractor who said they don t know what.

However in a test by the acoustic group in sweden researchers found that metal roofs emit rain noise softer than normal conversation and only slightly louder than a soft whisper.
