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.
under the overhang of the roof
The roof of a cave is referred to as the "ceiling" or "overhang".
A synonym for eaves is roof overhang.

eave The overhanging edge of a roof.
To ensure proper installation of a roof shingle overhang, it is recommended to follow these guidelines: Overhang the shingles by 1 to 1.5 inches beyond the edge of the roof. Use proper fasteners to secure the overhang in place. Ensure the overhang is straight and level to maintain a uniform appearance. Trim any excess overhang to prevent damage or water infiltration. Follow manufacturer instructions for specific installation requirements.
The recommended overhang for a roof shingle is typically around 1 to 1.5 inches. This helps provide proper protection for the edge of the roof and also enhances the overall appearance of the roof.
Truss
A 'Skylight' and a'Roof Truss' are 2totally different parts of a building. A roof truss is a timber or steel framework used to carry the roof cladding. A skylight is a panel in a roof which contains a panel of clear plastic or glass which allows the sunlight to shine into the room of the building.
a truss that is anchored at one end & overhangs a support at the other end
