Roofs of Long span structures are made of steel trusses. They are can be designed with glazing ( inclined glass panels towards north sky) on north side, since in northern hemisphere there is no direct or harsh sun light in north. It provides a very consistent light indoors. Now a days even south lighting is also used for a more intense lighting. Proper care should be taken for rain water draining at glazed panels.
A roof truss must be engineered to perform under specific load requirements. Normally, building codes require a structural engineer's stamp of approval on truss design. Trusses are usually built on a flat surface using various grades of wood, with plywood or metal gussets joining the various pieces of the truss together. Multiple identical trusses are built with the use of a jig.

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.
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.
