Hi and Thanks Frank.
Yeap i've definitely got the units of measure mixed. I've done as much research as I can on a lean to roof and i'm ok with the method without purling. guess i got some more work to do!
cheers!
Hi all,
I live in a mid terraced house which has an extension with a flat roof which I would like to convert to a lean to roof with two roof windows approximately 150mm by 100mm.
To my knowledge the max span of a lean to roof is 2.4 metres but what I want would exceed that by a metre or so...
