Is it normal for a roof to make noise. It s thermal expansion and contraction. Here we ll talk about the two most common reasons for a creaky roof. Or when it has come loose. The cracking and popping could also be from the joists or beams as they contract and expand.
Banging banging sounds generally occur when a part of the roof has not been properly fixed in place.

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. Taking as a given the noise is probably movement due to differences in thermal expansion or contraction as temperatures change rise fall across and through the roof structure in response to changes in outdoor temperature or sun exposure. This flexing is what s causing the popping noise.
The most common noise issues with flat roofs are banging loud rain snapping popping sounds heat related cracking and creaking. Metal roofs are major offenders but shingled roofs also can be quite noisy. The sound can be present both in mild weather and heavy winds.
