    Hello,

    I recently had a new roof fitted to my property and I noticed a few new water stains on a gable wall.

    The scaffolding comes down this week and I haven't signed off on the project.

    3 areas are currently showing wet patches.

    Should the guttering be placed underneath the dry verge so it catches the water that is currently dripping off the slates and in between the guttering and dry verge?


    Water is running of the dry verge onto the lead and onto the wall.

    Should the dry verge have been extended so that it allows water to run

    onto the flat roof?


    You can see on the video that water is clearly dripping in between the guttering and the dry Verge. Which is then dripping onto the wall.

    Appreciate any help or suggestions as to what will solve these issues.

    Thank you

    Update:
    I adjusted the guttering so that it is now positioned underneath the dry verge.

    Water is still running down the exterior of the dry verge and then onto the walls. Is this typical of a dry verge system. I thought the whole point of the system was to carry water away and to prevent water from dripping onto the walls.

    I foresee issues with wall staining and a saturated wall during the winter months.

    Sheet lead under slates and draped over gutters.
    Did you point it out to the roofers?

    I haven't as yet. on other areas, such as the valleys there is lead that is under the slates and then is draped over the gutter.

    but

    my main concern is the dry verge... that is dripping onto the wall.

    The dry verge is too short and not running into anything and that lead thing at the end a bit of a mess.

    Thankyou Woody for confirming my suspicion that the dry verge has been cut too short. This is definitely the case at the bottom edge where you can see that it doesn't run the full course of the slates.

    But

    what about at the top end? is that the reason why water is running off the slates next to it and then onto the exterior of the dry verge?

    If you can't move the gutter end cap over, then it will need some lead as per Alastair.

    The problem with plastic eaves is that it lets water run off it and makes problems like this, whereas a mortar verge would not.

    That bottom section will need a proper joint clip and a section of plastic verge adding and the connection altered at the bottom where the it meets the lead
