We're just building a single storey extension that will have a flat roof, with a parapet wall.
I'm having a bit of an issue with finding once weathered stone copings that will suit my needs and are within budget.
The width of the wall is 350mm, giving me a coping stone of 500mm, thus allowing a 75mm overhang each side.
Is there any reason why I can't use a flat coping stone (with the drip grooves), but use a thicker bed of mortar to create a slope towards the flat roof?
The building is of stone construction with around >25mm mortar joints, so won't look out of place if I thicken the external mortar bed up and slim down the mortar bed on the flat roof side.
Thoughts? Or is this a big no no? The coping stones, must be made from real stone.
