Thank you. I guess what I am really asking is can it be left as it is, or does it need remedial action. Is there an issue with wind driven rain. Is the mortar more likely to degrade with the the gap. Any suitable products to fill the gap?
Hope somebody can help.
My new build roof verge, has a small gap (purple dots) between the muck and the board. Is this anything to worry about? Does it need mastic or repointing or is it normal?
