Even though we had the photovoltaic roof array installed, I had a couple of items left on the roof project to do list:
The roof was waterproof since we installed the membranes and flashing. The same cannot be said for the parapet, which still needed a coping. We originally had clay tile coping on the parapet…
…but I opted for steel coping this time round to reduce maintenance and water infiltration issues.
The steel coping is secured by a cleat on the outside of the parapet, and as such has no visible fasteners. On the inside of the parapet, it needs to be fastened to a nailer that is anchored along the top edge of the parapet.
We used a pressure treated stud for the nailer, cut it to length, clamped it to the top edge of the parapet, and anchored it about every 24 inches.
