Have seen some fantastic aluminum coping online,having posted a similar question before,when I was thinking of using coping stone.

Aluminium coping comes with seals and looks all professionally desisgned to make the product water tight.

Have been told before with the stone coping,weep holes are required in roof parapet walls.


Does this also apply to the aluminum coping ??

Returning to my previous post, NHBC state 'where there is a exposed wall between the coping and flashing cavity tray should be installed..

If the epdm rubber membrane runs up and below the aluminium coping is there a need for weep holes on external render. (no exposed wall)

From top of coping to roof line is 200mm

Details on line so confusing, all I ever see is high parapet walls
