Hi all. The architect has specified a zinc roof on my bungalow extension.It has a
6.1m square base and is pyramid form 15 degree angle-must get my trig tables out-. The spec for the zinc is upstand tray type 600mm wide. I take it this is basically a lego job the skill being in cutting the angles on the tray ends?. How do the trays join together-clip over joining profiles? How do they join at the "ridge"?. Painfull one this-how do you get a point a the pyramid apex. Why are they laid on 25mm boards with 5mm gaps-anchors?. Where do I get the zinc bits-my builders supply merchants-all 3 cannot get them.
