Hi DIY Gal - I know this is an old thread but I found it because we just moved into a new house and have tongue and groove cathedral ceilings and are having the same problem! It's driving me nuts! I'm wondering what, if any solutions you may have found to fix the noises?

 

This thread is fascinating. I'm in a stick-built home for the first time, and I'm hearing cracks and booms and such, but they are very minimal. My neighbor has a shingle roof, and hears it far more pronounced than me. My house has "concrete tile" on the roof. They're like shingles, but made of concrete and they're at lest 1" thick. The home is easy to cool, and there isn't a whole lot of expansion in the wood. It's a 50 year roof, and it's on 30 years now; however, when you do have to replace it... the cost is astronomical. Like over 45 grand for a 2,600+ square foot home.

To answer your question, it all has to do with expansion and contraction, so whatever you can do to slow and minimize the temperature changes in the beams, whether that's planting / growing a big tree, or insulating the attic (or the gaps between the roof shingles and the interior ceiling) is really your only option other than redoing the house. Whatever you can do to reduce temperature swings in the attic.

 

In South Florida, all the homes are made of solid concrete, and most of the roof trusses are made of slash pine / Miami Dade pine.

HELP!  Anyone have any other ideas on how to correct this expansion/contraction problem when there is no attic space.  Same issue.

I have a Tongue and Groove flat roofed Eichler built house with similar creaking, apparently with temperature changes. Trees cool the roof variably with the path of the sun. I have caulked a bathroom to prevent moisture getting into the foam board insulation under the tar and gravel. I have thought of caulking the rest of the house and even caulking the roof deck at the next replacement. My 6x8 bathroom was easy, and there are various colors of caulk available.

Came here to report the same thing -- cathedral T&G ceiling, and a symphony at sunrise and sunset!

The house was always a bit noisy, but the percussion section really got going when we had a new metal roof and a plywood deck sandwiched with insulation above the T&G (the old roof had no insulation, zero! That first oil bill...). It was ok in the summer, a bit of pinging now and then, but now that winter has hit, it's... a lot! Loud pops, from random locations. But only when the sun hits it or leaves... so it's for sure thermal.

Now that I see that others have the same issue I'm actually relieved! The new roof is darker than the old roof, so the boards must be adjusting to the new thermal situation (and the added weight may hinder movement that was freer before, making the plate tectonics more dramatic.)

 Sooo... the roof is... probably not going to fall in!?? :D

Every material moved. Especially with changes in temperature. The only place for insulation on a cathedral ceiling is on the outside. There should have been allowances for the movement of the metal. Metal will expand and contract move than wood. Larger holes around the nails would have not had that issue. Also an air gap under the metal would have helped a lot.

The noise will never stop, there will always be movement. This is where a small building, or even just a roof built for testing would have told you this.

In our case there is an air gap, per code. However it isn't the metal that's making the noise, it's the T&G boards moving against each other. If you get up close to the ceiling when the sun hits it, you can hear it.
