Possible problem with loft conversion dormer roof Information, help and tips on many areas of roofing including trusses, tiling, venting, insulation etc....

Hi
I was hoping someone can offer me some advice please.
We had a loft conversion completed in Oct 2018 by a well known and reputable specialist in our area and we were really happy with the quality until we lost all the ridge tiles during storm Eunice. These weren't mechanically fix but I understand this isn't a legal requirement.
However the roofer I employed to replace them highlighted a potential issue with the dormer roof. It appears that sections of tiles haven't been overlapped enough and the roof has been "stretched" to finish on a full tile. He struggled to replace a few damaged tiles on the dormer roof because the were so tight and said this wouldn't of be caused by the storm.
I hopefully have included a few photos to show what i mean.
Does anyone have any advice as to whether this is acceptable or do i have a case to contact the company to discuss it further.
Any help would be greatly appreciated.
Thanks

Hi pavillion21,
You could try contacting the original contractor but since it is 4 year on I doubt you would get any positive response.
Your roof tiles should have been fixed in accordance with BS5534 (all ridge tiles must be mechanically fixed) but clearly they have not. Suggest you start by contacting whichever authority approved the building works.

Hi Stoneyboy
Thanks for the reply.
I thought I read somewhere that the BS5534 mechanical fixing wasn't a legal requirement.
I'll do as you suggest and contact the local authority.
Yes, so far no response at all from the original company.
thanks again
