That is the question. And no one really knows, it seems. My plan for the spring/summer is to get a flat roof specialist to come and have a look (builder did the roof himself). There are two possible problems from my lay point of view. 1: I don't think there is insulation between the joists at...

Thanks for the advice. I thought I would add some photos, although it's hard to pick them up well on camera. Do these look like plaster shrinkage cracks to you? Seems strange that they track along the line of the steel. Also, the day the plasterer skimmed the ceiling it was very hot, about 35+...

He said he used the right amount of fixings. Now it's cold when there's a frost on the roof you can see the location of the fixings and there do appear to be quite a lot, probably not every 200mm though. As you mentioned though, obviously they can't fix the roof between the joists. In this cold...

Hello, We had a 37 square metre extension built this summer. This involved knocking down the full width ground floor rear wall and installing a steel box frame to support the first floor and new extension flat roof. The works were fully completed (decorated to finish) in September. Now we are...

I just spoke to the roofing system manufacturer (Cure it). They said creaking and banging is most often caused by using too few fixings. The boards should be fixed every 200mm to a depth of at least 40mm into the joists. Will be taking this up with the installer to find out what he did. Given...

Add another to the list... Had a ~35m extension built this summer with a GRP flat roof. Every time the sun shines it creaks and bangs, sometimes very loudly when the sun is strong. We have a warm deck -> no insulation between joists, T&G OSB boards with 100mm insulation sandwiched inbetween...
