Hi all had a roofer put a new roof on a chapel for me, few questions re the grp dry valleys.

1) Are they ok being cut as short as in the photo? There is lead below the remainder of the run however I thought the dry valley would extend a bit further down as they do on the rest of the dormers, Is it an issue or should i just ignore?

2) Also at the top of the dormer where the 2 dry valleys meet he's put some sort of sticky membrane over, is this sufficient?

Thanks

It's not unusual to cut the DV short of the fascia, then extend the remainder of the valley in lead, owing to the unbendable nature of the DV.
