Creaking noise from roof when windy, and intermittent cracking noise

New-build house 18 months old. When it is windy there is a creaking noise from around the edges of the roof area which is heard very distinctly in the bedrooms. The builder has brought in the roofing contractor who seems to have no idea what is causing it. They have decided to seal the joins in the roof lining membrane but I don't this is the problem, although it does visibly ripple in windy conditions. Wondering if there are issues with the roof trusses which extend out over the external walls.

There are also intermittent cracking noises from the roof - is this due to normal settlement and drying out of roof timbers, and will it go in time.

I am wondering if we should get a structural engineer in to check that all has been built correctly.

Thanks for any advice.

Hi I think you will probably find with the creaking is its just the guttering subtracting and expanding with the change of weather conditions but this is normal.
Hope this helps Keith.

sounds to me if this could be to do with expansion and contraction.
was the build timber frame?
does this occur during certain temperatures differential conditions? hot then cooling
one would assume that relevant inspections were made for restraint of floors,roofs and wind bracing.

Movement in guttering/soffit/fascia all been checked and secure? New property tiles roof verge caps moving/rubbing together?

Best of luck.

have you had this problem from the start since you moved in or is this something you have noticed more recently? is the builder being cooperative if so ask him who the architect/engineers were that did the original design works and try to get a consult from them (As this would probably be free) Movement in a breathable membrane would not cause cracking noises as you describe, I would also consider sitting in the loft with the lights on while the wind is blowing as this may make it glaringly obvious. Is is a constant noise or just occasional. Lots of different factors could attribute to this.

Potentially the timbers are contracting and expanding due to temperature changes and moisture changes. This could be timely with how you heat your property and external temperatures.

And, the wood used is usually from a different country, it needs time adjusting to Britain's climate. Without enough time to adjust prior to installation it could have a lot more retraction/expansion and risk the integrity of the roof.

Alternatively, the problem can be dependent on the property being properly ventilated.
Too much ventilation could allow wind to disturb your rafters, ridge beam or loft floor structure if not secured correctly.
Too little moisture, not enough ventilation
and a hot house dries your wood out too fast. You don't want your rafters to be too dry, rigid and unable to handle pressure well, causing creaking and affect integrity of the roof. You want a maximum of 20% moisture in your wooden roof structure, rot will take place given high moisture and time. About 10%-16% is best for roof stability.

I'd ask your neighbours if they experience the same problem. Checking if the wood used is the same wood, moisture levels. If it isn't a problem elsewhere with the house ventilation facing the same direction, perhaps the joiners/roofers that fitted the new build didn't correctly tie/nail/screw the structure together. If your neighbours aren't experiencing the same issue, possible red flag.

To check for expansion/contraction you'd measure gaps between joists to see if the wood is still spaced to size of the building regs and planning and if the require sized nails/screws/ties are used as per building regulations and planning.

A lot of cowboy roofers. Your roof could have been fitted on a Friday. Hopefully not haha. Get a professional out to investigate and I'm sure you'll find your answer.

Could be as simple as fixing a few joists more securely together and adding some draft exclusion.
