Lifting tiles and gaps near valley

[steveoelliott]

Hi Folks,

 

I hope I don't make myself seem stupid here but I am certainly no roof expert... However, I've noticed that on my roof where the old house meets the extension and there is a valley, that some of tiles on the original roof seem to be raised and have small gaps underneath. I know some of these tiles have been removed previously to allow timbers to go into loft.

 

Is this any cause for concern? Is this much work to resolve?

 

Thanks a lot in advance...

As long as there is felt or sparking under the tiles they should be fine 

Though the bottom section would

 benefit from pointing where they meet the lead

It looks like the bottom may be sitting on some stones or random bits of mortar and thus not sitting quite right.  Maybe lift them and remove any random bits so they sit better.  The bottom two could then do with pointing to fill the space underneath them with mortar like the others above them.

Never rely on sarking membranes to keep water out! 
 

tiles should really lap further onto the lead on the bottom Course but strong mortar pointing will likely suffice

Thank you for the feedback. So I presume it isn’t anything that major to worry about but I will get those valley bits repointed by a local roofing company and have them check the tiles lifting and gaps at the same time.
