Loud popping in ceiling or attic since newer insulation and roof

M Miles | Posted in GBA Pro Help on

We live in the northwest. In the winter there is no noise. As soon as it starts to warm up there are very loud popping noises that sound like they are coming from the attic or ceiling. Wondering about heat in the attic. Workers said there is a lot of insulation – not sure what kind.

Any ideas what to investigate?

    100% normal in a wood frame truss ceiling home. Wood expanding and contracting and nails popping. I wouldn't worry about it.

    Do you have a metal roof?

    Thank you for responding.

    No, it is a composition roof. I have always had similarly built homes with composition roofs and have never heard anything like this - loud and often. Visitors comment on it.

    Thanks for any ideas.

    Well, next thing to do is inspect the attic. You want someone with lots of building and/or building inspection experience, perhaps a home inspector.

    SIP roofs can have this... here's a thread from 2011:

    "I have a SIP house (OSB skins) with an unvented metal roof (2.5 years old). It can be incredibly loud....think Nolan Ryan throwing a baseball against the roof. It's annoying enough that I'm considering pulling up the metal roof so I can add furring strips and ventilation between the SIP and the metal.
    As others have stated elsewhere, the problem seems to be most acute during mild, partly cloudy days. On these days, I can literally watch the sun go behind the clouds and tick off the seconds before the roof pops. Now that it's warmer here in Virginia, the popping frequency is less.
    There are plenty of reasons not to build with SIPS (I wouldn't do it again)...the roof pops just add to the list, in my opinion.

    Is it a SIP roof? I saw no mention of that.
