Each roof truss is structurally designed for a particular situation. Where a truss overhangs or extends beyond a supporting wall, so that the truss is partly cantilevered (e.g. in a deep eave), the calculations by the truss designer will take this into account.
They each have their place, but on the same style roof, trusses would be stronger.
100 feet long 4 1/2 pitch
A truss is the triangler wood frame work for a roof. Rafters are the singular peices of wood put between them That make up the begining of the celing
Roof trusses are designed to counter the weight imposed on them. If your roof is completed tiled EC. and looks out of shape. I could be. Wrong design/ trusses too wide apart/ roofs 600mm apart tended to sag between/ the load bearing partition under truss higher than external walls. seen this before completely distorted the whole roof.
When talking about the area of a roof, remember that it is not the same as the square footage of the structure. For example a 20 x 30' building with a 12" overhang and a 4/12 pitch will have 736 sq ft of roof vs only 600 sq ft of slab. One square of shingles covers 100 square feet. 15 year shingles come 3 bundles to a square. 25 year come 4 bundles to a square.
A roof overhang is generally just called a roof overhang unless you are referring to a specific part of the overhang.
There is no "standard". It depends on the construction, dimensions, and the overall goal/intent of the roof overhang.
The roof of a cave is referred to as the "ceiling" or "overhang".
