Cut roof
Cut. Cut roofs are exactly what they say they are, the advantages of a cut roof, building can commence immediately, there are usually no structural members congesting the roof space so this type of roof is ideal if an attic is to be used as living accomodation. More complicated structures can be moreeasily constucted in the cut roof design.

Trussed roof
Trussed. This type of roof is made up of a series of "trusses" that are manufactured off site and brought to site and assembled, they can be extremely versatile and have the advantage of speed it is also possible with a trussed roof design to incorporate a partly cut roof , to include dormer windows or any variation on a theme.

Some roofing basics
There are three main types of roof construction
Flat . This is basically an out of level floor with a water resistant covering falling to a water outlet.
flat roof is a type of covering for a building. In contrast to the more sloped form of
roof,
a flat roof is horizontal or nearly horizontal.
The slope of a roof is properly known as its pitch: Roofs which are nearly
flat are known as low-pitch roofs (as the angle of slope increases, so the pitch
is said to increase).
Any sheet of material used to cover a flat or low-pitched roof is usually
known as a membrane and the primary purpose of these membranes is to waterproof
the roof area. Materials that cover flat roofs typically allow the water to run off from a slight inclination or
camber into a gutter system. Water from some flat roofs such as on garden sheds
sometimes flows freely off the edge of a roof, though gutter systems are of
advantage in keeping both walls and foundations dry. Gutters on smaller roofs
often lead water directly onto the ground, or better, into a specially made
soakaway. Gutters on larger roofs usually lead water into the rainwater drainage
system of any built up area. Occasionally flat roofs though are designed to
collect water in a pool, usually for aesthetic purposes, or for rainwater
buffering.

In architecture and structural
engineering, a truss is a structure
comprising one or more triangular units constructed with straight members whose
ends are connected at joints referred to as nodes. External forces and reactions to those
forces are considered to act only at the nodes and result in forces in the
members which are either tensile or compressive
forces. Moments (torques) are explicitly excluded because, and only because, all
the joints in a truss are treated as revolutes.
A planar truss is one where all the members and nodes lie within a two
dimensional plane, while a space truss has members and nodes extending into
three dimensions.
