Noise from GRP flat roof

Grp is for boats

GRP is NOT a quick easy substitute for felt/lead/whatever. It can be successful but that relies on preparation, application and climate.

My roof is a cold roof still very noisey. There seems to be alot of people with gpr roofs that are very noisey why are they not been regulated by someone if there are problems with them why are they been still sold without customers been informed of how disruptive they can be to our lives and homes . They are not a cheap option either you think you are getting a better roof but unfortunately not

Ours is the same (approx 6x6m GRP warm roof built 2022). The expansion noise is horrendous.

I’d like to know what went wrong in the construction. Surely not all GRP roofs do this?

I am never getting a GRP roof again (or even any flat roof to be honest). Nightmare.

Our roof is a cold roof nightmare there should be someone regulating these kind of roofs . If you want to sell your home no chance now . Not cheap either think you have a better roof but not Have you resolved yours ?.

No nothing resolved. It is a case of living with it for now.

The crappy builders left me with several other substandard issues that take priority.

Interesting to hear you have same problem in a cold roof. If you get yours fixed please update this thread.

Interesting video on fixing the GRP noise problem. Also read the comments : noise blamed on not enough fixings/not hitting the joists, lack of expansion joints, absence of vapour membrane under the insulation.
