Hi all, new to using this but figured why not get some opinions.
i have built a flat roof extension with a parapet wall (block) and want to ask the simple (I hope) question … “can I lay stone copings onto roofing felt?”
The parapet construction from externals side inward is sand cement render, 100mm block, 100mm cavity, 100mm block. When I built the roof I had to vent it so I have a 25mm vent on the inside side of the parapet, I capped it with cavity closer and OSB. The roofer the three layer felted my flat roof up to the underside of my vent and the top of the parapet. Where no vent the felt runs up and over the top of the parapet as you’d imagine.
I was going to do ali coping but gone off it for a number of reasons, one cost.
Please let me know your thoughts and if what I’ve said is not clear let me know. Thanks in advance and appreciate any comments!!
