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.

Sounds like a cut, bend and solder job to me...

No its not a cut and solder job- these days are long gone--unless you own a
100 year old property.
The modern metal roof requires an absolute minimum of effort to
erect-but-its got fiddly bits in it eg steel panel roofs are held on by J
bolts on the upstand ridge-put the bolt on the flat-leak-J bolt should have
rubber gromet on it-no gromet-leaks again-these roofs go on fast but the
detailing is vital for a leak free roof.
