Dry Verge its the bain of my life

[Broadie451]

About 2 years ago I had our house re-roofed as part of an extension, and I was advised by the roofer that dry verge was the way to go. Since then I have suffered with drips from the dry verge systerm hittng the window ledges keeping me awake at night and also dampening the brickwork, not only this but when you go into the loft the is a draft from the gable end because the isn't any form of seal to the outside world.

Is there anything I can do about this I have given up on the original installer I have accepted the fact I will not get any joy out of him.

If I remove the dry verge system can I seal up the void space between the batons/under felt and the wall with morter/expanding foam???

Does naybody have any tips on refitting the dry verge system to prevent the rainwater spilling over the side and dripping down the walls.

Any help on this matter would be greatly appreciated.
