This detail is on a curved roof; consisting of insulated metal roof panel (curved) on structural roof beams/purlins/girder’s (whatever it’s called in your region of the world). It has an eaves junction with an external wall and requires a profile gutter (that matches the roof manufactures detail or is a commonly supplied element by the roof manufacture) and has a few other elements such as wall plates, cavity closers, fillers etc. The other cross section show the verge detail in which the side of the roof panel meets the wall, this joint needs to be covered with a verge board or special flashing piece. Below are the 2 initial sketch sections and a list of objects I think are in the detail.
The next post will be video modelling of this detail, will try have it posted by the end of next week.
