The simply arranged rooftops are from the closet to fit the foot of the feet on the horizon on a plate on the top of each wall.  The upper ends of the padded particles are often happy on the ridge but can be direct to other rafts to make a pair of scaffolding called the pair. Depending on the material of the roof covering, horizontal casting, coil or purlins for fixing on the cooking stove; or plates, plywood or oriented panel plates form a deck (also called foil or sheath) to support the covering. Harder under purlins or purlin plates is used to maintain a longer width of the rafter. Crane beams, which can also serve as a ceiling beam, usually connect between the lower ends of the opposite piles to prevent the spread and force of the wall. These beams or cow hangings can be repaired more than the opposite scissors for added strength. Shears, beams, and slabs are used to convey the weight of the roof on the walls of the building
Construction of a truss roof
A truss roof is with wrap and jar. The passage in the hill plate is a space that is designed to allow natural ventilation. Processed roof racks come in a wide range of style. Designed by the country of origin for each specific building. Wooden branches are created in different styles of wood use or metal joints. The economical woodworking processors are usually arranged between 8 feet (2.4 m) and 12 feet (3.7 m) separated by the mainframes. The main scissors can be mixed with common rafts or carry a common purlin
The roof framing should be designed to withstand the structural burden of students and loads called dead load, its weight and the weight of the roof cover and additional load is called environmental stress, snow, and wind. Fleet roots can also be designed for live loads if people can continue by their name. In the United States, citizen codes define loads in kilograms per square foot, varying across regions. The load and range (distance between the carriers) define the size and distance of the scissors and shoes.
Solar panels on the roof
Solar panel systems consist of state-of-the-art solar module modules or mounting frames for mounting roofs. Roof mounting brackets include:
- Poly racks, which are fastened directly to the roof structure and can use an additional rubber for fixing the rack module or frame.
- Ballast support brackets, such as concrete or steel bases that use weight to provide a system board in a position and not a sealed penetration.
