Octagonal roof

bet_ | Posted in Construction Techniques on April 27, 2003 09:36am

Hi

I’m building an octagonal cabin. Got the rafters figured out (and made a model so I know they work).

I’m hung up on some other details.I plan a metal roof (I’m in snow country) and I’ve nevr worked with metal roofs. I need help in figuring out the details of A) ventilation-how to put vents into meal roofing and waterproof it and B) how to finish off the peak-ie weathr proofing detail C) anybody got any bright ideas of how to best rope off when working-I’ll be alone alot and far from any help.

I hope someone out there has done this and has expriance to pass on……..

Thanks so much

Bet

    Will this be a raised rib type metal roof, standing seam, or metal shingles?

        Panel lays flat on roof decking surface with standing seam and there are no exposed fasteners. more time consuming and higher skill level.

        On yours, sheath and dry in with tarpaper, then, if you run 1x4 strapping horizontally, you have a chicken ladder to walk, a ventilation system built in, and a fastener location stipulated.

        cut sheets to fit angle to the hip. moist air will vent out there.

        apply the flexible gnarly ridge vent material and screw the metal ridge over it. Taht will keep most bugs out.

        After framing, install a large eyebolt at the top peak for your safety gear to couple up with. Design a cap to be welded up and painted to apply when finished. It could have an eye bolt in it too..

          thank you.

          'dry in'-not familiar with this term.?? means ?? (My guess is it means apply tarpaper for so many inches either side of hip??)

          I assume that you think 'standing seam' is a better choice than  standing rib because no exposed fasnrs..?

          Thanks alot  for your time-got some valuable ideas/info

            dry in, around here means felt on the roof and windows in so it if it rains it doesn't get wet inside.

            It's also a loose term around here because it doesn't mean roofing on which I find odd because water will ALWAYS find a way in even with felt on.

            To a framer or a abnker reading the draw scedule on the payment contract, dryed in means roof on and doors/windows installed.

            To a roofer - the subject under discussion, it means tarpaper on roof to keep 95% of rain out for a few weeks while the exterior trim carpenters tear it to shreds. About what he assumed..

            When I worked in st louis it meant roof on, here everyone I have talked to at the company I work for and the roofing subs we use consider it just tar paper

            along with windows and doors.

            Maybe its just the guys I'm working with....View ImageGo Jayhawks..............Next Year and daaa. Blues View Image

        "ummmmmmmmmmmm, well I was picturing raised rib-I..."

        Which made me think - Yummmmmmmmmm, braised rib eye steaks for dinner. I'm firing up the grill.
