Roofing treatment when installation

Roofing treatment when installation is important factors that affect the integrity and durability of a house located on the roof of the residence located on the roof of the house. If there is damage to the roof of the house then the damage will spread to other parts of the building. For example, if there is a leak in the roof of another building section below it will receive the effects. The roof frame made of wood, for example, will rapidly decay if frequently exposed to water seeping through the field leaking roof. This decay occurs because the roof has become moist due to water. Even the ceiling will be damaged and appear with the ceiling that is not beautiful anymore because of the stain areas such as water droplets. Paint ceilings and walls may be dirty or even peeled off due to water seeping from the roof. In addition, termites will be easy to attack because of damp conditions. Yet termite attack is very dangerous.
Roof truss being attacked by termites will have porous. Even termites will continue to attack the frame house to the household furniture made of wood.

Roof treatment is not done after the house is complete, but should be started in the roof is done or installed. At the time of installation of the roof, things to note are as follow:

a. Splicing materials must be in accordance with predetermined criteria.
b. Installation must be careful. Installation is not careful pairing often occurs in the bunch, namely the inner bend connection. Eaves trough the size and lack of appropriate size causes batten installation would be less tidy and less flat so that the installation of tiled poorly or not the meeting.
c. Election materials must consider the durability of these materials, especially the attack of termites.
d. Termite prevention needs to be done in the following way:
1. Use of serum anti-termite. Serum was sprayed on the foundation hole and area floor coverings.
2. Wood materials for the roof and sills, windows, and doors should be given anti-termite liquid. Dyed by gift. Workmanship of the most inexpensive and simplest is to use the residue.

Roof construction

A simple ridged roof consists of inclined rafters that rest on horizontal wall-plates on top of each wall. The top ends of the rafters meet at the horizontal ridge plate or ridge beam. Horizontal purlins are fixed to the rafters to support the roof covering. Heavier under purlin are used to support longer rafter spans. Tie beams or ceiling joists, are connected between the lower ends of opposite rafters to prevent them from spreading and forcing the walls apart. Collar beams or collar ties may be fixed higher up between opposite rafters for extra strength.[1]

The rafters, tie beams and joists serve to transmit the weight of the roof to the walls of the building. There are a number of structural systems employed to facilitate this, including the use of wall-plates set at the top of the wall, hammer beam, which spread the weight down the wall and create an equilibrium between outward and upward thrust, king posts which transfer the weight of the roof ridge, and various types of trusses.

In cyclone and hurricane prone areas the main engineering consideration is to hold the roof down during severe storms. Every component of the roof (as of course the rest of the structure) has to withstand the uplift forces of high wind speeds. This is not normally a problem in areas not prone to high wind.

Modern roofing technologies, apparent in the accompanying photo of a house under construction in a cyclone-prone region of Northern Australia, include the purpose-made steel hook bracket which is bolted to the truss with M16 bolt. The bracket is bolted to an M16 bolt cast in situ, embedded 300 mm into the reinforced concrete block wall. This system is typically in place every 900 mm around perimeter.

Wood roof
Wood shingles are constructed for additional conventional grace houses. They are built from tempted wood also hold up in four season states where the weather does not get to the excessive. They are very beautiful also many people are favoring wooden shingles now for their houses.

For homeowners who choose a extended natural or rustic of, the best of the major forms of roofing is wood shingles or shakes. Machine-sawed from southern pine, cedar, or redwood, wood shingles are immense on log homes while wood shakes, with their irregular edges, acquire a recent sight to a roof.

Wood shingles and shakes, however, constrain factory treatment to construct them fire-resistant. Untreated wood shingles also shakes may not be accepted in some regions of the country.
