    Default Maximum gap between corry under ridgecap?

    What is the maximum gap I could get away with on a ridge roof (36 degree pitch) under a normal 300mm wide roll-top ridgecap? Like, the gap between the two sides of the roof? The gap at the top here: / \

    Reason is, there's some second-hand new corry up for sale and I might grab it -- only, it's a tad short and will need around 120mm - 150mm (5 or 6 inch) gap at the ridge. For a backyard shed.

    Edit/update -- well, I drew it out on paper, and looks like that gap still leaves plenty of roofing under the ridgecap, especially my steep roof angle, so I'll go with it.

    Fair enough, and for future reference, you could get the ridge cap rolled larger than normal if need be, at places such as Lysaght etc
