POP/CREAK SOUND from attic/new roof???

[infiniteMPG]

We own a block house in west central Florida built in the early 1980's and several years ago we had the entire roof rebuild with mostly new plywood and all new shingles. About six months ago we were in the living room and heard a rather loud CREAK or POP sound come from the front hallway. Almost like the occasional creaking sound you heard from a house settling, but after hearing it several times over the next several days we noticed it was coming from the attic area. Have noticed it's mainly when the temperature is changing, like after the sun has been up a while or after the sun has set.

Also have heard this in other parts of the house at different volumes but most prominent in the front hallway area. I have checked in the attic and seen no visible things out of sorts. Just never heard these sounds before and the roof work was done 5 or 6 years ago. Would like to find some way to determine where these sounds are coming from and take some precautionary measures if something needs work.

Thanks in advance for any and all assistance, Thanks!

does it occur when the temps are going up or down? if so, it's expansion/contraction.

It might also be plastic gutters expanding/contracting if they haven't been installed properly - they can make quite a noise, too.

Given that the OP's in Florida, I suppose we can rule out snow/ice falling from the roof ;)

Normal thermal expansion and contraction. Should work itself out and quiet down with time. Heard it on my siding when house was new. Siding has elongated grooves for nailing and should not be nailed too tight because of this. Roof not made the same but no surprise that there is occasional noise.

Seems to happen more when temps are rising (sun coming up) then when cooling (evening) but have heard it late at night occasionally. Would of thought the roof would of "settled" over the last 4 or 5 years of brutal summer heat and chilly winters (maybe just a week or two, but still below freezing). Anything that can be done about it (beads of contractor adhesive between roof plywood and 2x4's or something like that?) or just something to live with? Sometimes it's pretty loud and since it's in the front hallway it sounds like someone at the front door :O/

No gutters so can rule that out :O)

Look especially at the sunniest portion of the house when you hear it early in the day....ductwork, ac, pipes, rafters...something knocking when something else is warming/cooling. I lived a long time in Florida, but never had that sort of noise....only an occ. rattle, like mild earthquakes and I lived in sink-hole area :o) In a different location, I used to have clunking noise from aluminum siding as it warmed and cooled.

Did you just get new hearing aids??

[aemeijers]

Shrug. The roof on my addition talks to me as the sun goes down. Trusses sliding on the tops of the interior walls, I expect.

LOL.... nope. Didn't get old ones either. But did remind me of when my MOM finally won her battle to get my Dad to get his first hearing aids. She was driving him home on a nice day and he looked surprised and wanted to know what that noise was!!! My Mom explained it was the wind coming in the car window.... LOL

The creaking noise is most noticeable on the side of the house with the most sun exposure in the afternoons. What bothers me is the sound is like the sound you'd hear if you pried on a stuck nail and it first started to come loose... that *POP* noise :O(
