Tiles lifting?

[James-the-doubter]

Hi all,

I had completed my extension last year and all has been well so far, however I have done a post winter walk round to start on some of the finishing jobs and noticed some tiles that appeared to be lifting. Can anyone offer an opinion on whether this is anything sinister? My initial plan was to get up there and try to reset the position rather than give the roofers a call back for something that appears relatively straightforward

looks suspicious can you get a picture close up on the white edges?

Hi, thanks for the reply - yes i can but i'll need to get up there to get the photo. Will try and get this later today.

Hi, a couple of close up photos attached.

ok, looks to me like Redland 49 in 02 brown with third round hips.
im guessing the batten ends are not secure and floating.
when the dry hip was fitted they could have caused the floating battens to bend
I cant see any hip trays
