Have a look at how the fasia is pulling away from the rafters.
You are missing the liner, the 2x4 or 2x6 nailed to the end of the rafters that the 1x6 and fasia is nailed to.
Don't know if that's the noise but I wood knock that back in place and drive some very large deck screws in there.
 
That fascia is a brand new piece of wood installed just before we bought the house. They had an old patio cover attached the the original which was rough sawn. It isn't flush because the tiles and insulation are pushing it funny. I can try and suck it up but I don't think it is going anywhere.
 
So if they changed the fasia, the weight of the first row of tile is one the 1x6. The tongue and groove is what allows it to span the distance between rafters. The noise indicates a problem. all we can do is look for problems and that is one.

I'll take the 1% chance the 4" insulation is not there, maybe 2", The fasia don't seem to be wide enough to hide 4" but with foam I'll go back to wondering if there are sleepers to nail the tile to. If not how long do the nails have to be to hold the tile go thru the foam and go into the wood no more than 3/4". As the foam would give the nail no structual support the bending moment would be at the wood deck. With a few tremblers I could see the tile pulling at the nails, bending them in the downward direction.
Still don't no if anything here would cause noise everynight.
 
Yup, stupid sun.

I didn't get any pics but I did dig around a bit. My roof is 1" T&G with 4" of foam insulation then ply and paper then tiles. I'm 99% sure on this.

And how is the Plywood and foam fastened...screws, nails, washers, glue?

I think this is where the expansion is at different rates when it cools down...then it POPs and it moves on the foam. I have seen this happen before but with metal roofs.
 
The weight of the tile along the bottom edge should be bore by the bird stop. The bird sop is the half round pieces in each flute of the tile and they should be nailed into the roof deck, not the fascia.

Does this noise happen on cloudy days?
 
That's a view of the fascia, the tile flutes and bird stop.

must be camara angle, just looks strange.

Anyway, noise indicates something is moving, The weight of the tile is sitting on sheeting that is overspanned.

Would just add a 2x4 from the ground to the underside of that span, wedged just a little to see if that changed the noise.
 
Alcohol makes funny pictures.

Where should I wedge the 2x4? The noise is worst in the master and second the living room, the kids rooms not much at all. So worst is the east side gets better to the west.

Back of house faces south and gets sunn all day long.
 
In the photo the first 1x6 isn't supported between the trusses near the fasia, so just in the center of that 1x6 between each of the rafters.
 
no attic ? where do you store the Christmas decorations? grand mas old picture ?

that hideous sculpture crazy uncle gave you?
 
when I moved in here. I had to school the garbage man.

I put out 6 bags of garbage, He took five and left one. the next week,

the same bag was out on the curb, when he went to pick it up, the bag ripped

cause it is a cheap bag, been in the sun for a week. He lift the stank garbage on the ground.

So I called his supervisor, someone else was sent out to clean up his mess

evidently, his brass was chewed. because I can put out as many as I want and they picked up now


but, I hooked him up, before Christmas. pint of jack black on top of the can
with a red ribbon
