Roofs at Structure
Structure member that’s constructed at top of the building to eliminate theeffect of rain, snow, wind, hot and cold weather.
Roof project must be consist of top (plan), front, right and left side views asfloor project.

Roof Plan, View and Surface Members
Roofs are categorized within the number and shape of sloped surfaces.Limiting lines of roof surfeces are given below.

Coordination of Roof
Inclined surfaces and places of ridges are designated and merged accordingto plan of structure. Separate the roof plan with rectangular shapes andcombine the angle bisectors at cross section points from rectangular shapes.

Roof Trusses
The roof member system called as roof truss that gives loads from slopedsurces of roof and transport these loads to the supports. Roof trusses aregenerate the main load bearing system and arranged by 2.00-3.00 m spaces.
Type of Roof Trusses1. Due to using material• Wooden roof trusses• Steel roof trusses2. Due to load bearing and transporting styles• Set roof trusses• Suspended roof trusses
Roof trusses -both steel and wooden ones- are designed by set orsuspended methods according to load bearing and transporting styles.
Roof Trusses
Materials and Size of Wooden Seated Roof Trusses are given below:
• Reinforced Concrete Slab• Post (8x8, 10x10, 12x12 cm)• Rafter (5x10 cm )• Purlin (8x10, 10x12, 12x14 cm)• Brace (5x10 cm)• Strut (5x10 cm)• Bearing plate (5x20 cm)
Seated Roof Trusses are named according to number of generated posts. The relationship between space of roof and number of post is given below;
• 4–6 m length have one post,• 6–8 m length have two post,• 8–11 m length have three post,• 11–13 m length have four post,• 13–14 m length have five post as generated.
