Metal roof thermal expansion noise.
As the lumber expands it moves and it will rub against other pieces of wood that aren t moving at the same rate.
On 2017 03 01 by anonymous slate roof prone to cracking noises is a slate roof prone to cracking noises because of thermal expansion and contraction.
The sun hits your roof and heats it up.
As the lumber expands it moves and it will rub against other pieces of wood that aren t moving at the same rate.
I have a high moisture reading in the morning and but the attic temperature is close to the outside temperature and by mid day the spread between the attic and outside increases to around 20 degrees and the moisture reading will goes from wet to dry.
Exposed fasteners often perform poorly due to its likelihood to leak.
Roof noises may be described as those attributed to an obvious source.
As for the popping noise in the morning and evening that s a different mechanism.
Sounds can be amplified by friction between the components in assemblies with standing seam roof panels rigid board insulation and metal decking.
This movement creates the popping noise.
Installing an underlayment between the metal roofing and the roof sheathing is a key step to reducing metal roof noise.
How much depends on the structure system and installation.
Hidden and exposed fasteners create different environments for thermal expansions.
In rare cases in one particular roof assembly with standing seam panels the expansion contraction sounds can become louder inside a building.
It s thermal expansion and contraction.
This is a step that must be taken during the installation process.
My dwelling has cathedral ceilings and we have a problem with thermal expansion contraction causing a banging noise after sunrise and at sunset.
It is possible that the roof popping noise is due to your metal roof pushing against the exposed fasteners.
All metal is going to make some noise with expansion and contraction.
In addition its design does not allow metal roof thermal expansion.
Install a higher quality roof.
It s thermal expansion and contraction.
