Having worked out the geometry of the green oak elements of the roof (see Roof Geometry), I looked again at the softwood part of the structure. As tends to be the case when faced with a challenge, I turned to Google and found this brilliant website which has ‘calculators’ for all sorts of roof types – blocklayer.com. I chose “Hip Roof Metric’ and entered the parameters for my roof:
And the calculator gives you all the information you need to build that roof right down to the angles of all the cuts of all the roof elements. This has saved me an awful lot of time and research.
Full dimension details for the common and hip rafters:
End detail of the hip and jack rafters:
And a useful summary of all angles:
Thank you blocklayer.com.
