Can anyone recommend a book or website that gives clear instructions on how to
build a roof and ?
I intend to do some roof alterations and build a porch that will fit into an
existing roof.( With valleys)
What I`m looking for is the correct and accurate method for the measuring and
cutting of the various lengths and angles/ bird-mouths etc . when creating the
I`m a reasonable D-I-Y`er so I feel fairly confident that I should be able to
construct it providing I know ( and understand) the correct way to do it.
Any suggestions welcomed.
As it states, when you buy a roofing square, you get instructions on it's use.
I've seen other websites but can't find the urls at the moment. Try a google
for Cut Roof or similar wording
Cut roofing is relatively straight forward. When starting out it is almost
inevitable that you will make some cutting errors.
Once you get you angles right, cut some plywood jigs to mark out the rest.Make
everything is level and plumb as appropriate.
Even if you cut to fit on a drunken roof, laying tiles on a roof that is on the
piss is a real pain.
When you fit the tiling battens, make sure you gauge off the top edges. Battens
notoriously variable the width and if you gauge on the gaps you get tiling that
wanders along the row. Been there, done it, taken it all off again!!
