<p>Thanks for the information , At the vent it was stretched to a 14 " space the sheeting inside and out side is 3/8" exterior glued and screwed and the span is between the bathroom wall lowering it by 50% . The construction of the roof has made it a torsion truss as it is a single piece , the only hole is for the fantastic fan which will be elevated on a bevelled 1x4 frame .

<p>A little update , The new roof is coming along , the framing is complete and interior ceiling installed .

<p>A little update , The new roof is coming along , the framing is complete and interior ceiling installed . I framed the roof with 2x2 [ ripped from construction 2" stock ] in 4x8' sections on 1' centers and sheeted with exterior 3/8 rough plywood . The ply wood had all edges sealed with 4 coats of spar varnish the first 2 thinned to soak in far , the best face left rough and stained white the glued and stapled to the framing . The roof sections were then installed on the unit and secured to each other and the walls with 3, wood screws spaced on 12" centers . I am now installing the interior lights and wiring , testing , insulating [ 1 1/2 " foam ] , putting exterior sheeting on , fiberglass taping all seams and joints , and fiberglassing the complete roof . This roof will be able to be used as a viewing platform . It is hoped to have the exterior complete with in the next 30 days . </p>
