Thread: Truss supports??

You can buy a kit at bunnings which bolt to the trusses and penetrate the roof to support rafters for an exttension. you have to cut a hole in the tiles or metal roof and you get a seal to go round the post and seal the roof. It does rails the roofline of the extension/pergola above the gutter though. i have used a similar kit to fit a 50x50 steel post to support a sail without any problems. the special one to suppor a beam has a bracket on a post which is bolted to the trusses.

my paito is as Pusser said, above the gutter line. It has advantages by letting smoke out when you fire up the bbq, you always get a breeze through no matter wind direction. our roof size is 6X9 giving a floor size of 5X8. due to the house being an "L" shape, we filled in the L to make a square. due to this we had to raise the outer edge a little higher so that it remains above the gutter. But in saying that, for the size we have, it is approved for cyclone rating for Nth Qld and only has two posts that are attached to the floor.
one thing though, rather than use colourbond, see if you can get that composite stuff with the foam sandwiched inbetween colourbond and something else. a bit more expensive, but when it rains it doesn't deafen you. i wish i went that way. Then you can also run cables through the foam for fluros and speakers if you desire.
i got mine done by a national mob, so how to i can't give advice....
