Semi-palm roof. Its structure and components

The roof is both a protection of the house from the weather and its decoration. In areas characterized by constant strong winds blowing from the front of the house, there is no better hip structure for the roof.
What is a hip roof?
A four-pitched roof with triangular end slopes extending from the ridge to the cornice is called a hip roof. If the end slopes (hip) do not reach the cornice and break off, then this type is called a half-hip.
The so-called semi-hipped gable roof differs from a simple gable roof by the presence of small overhangs at the ends. This design allows hip roofs to withstand severe wind loads. To its advantages, you can also add better protection from precipitation, less windage. Both the four-pitched and half-pitched gable roofs give the house a more aesthetic appearance.
Half-timbered roofs have a complex design that is not predisposed to saving material. Nevertheless, they are very common.
Components of a half-dome roof
The hip roof is very similar in design to the gable roof truss system, with the exception of the beveled edges. The so—called "roofing pie" is laid on the erected rafters, which includes the following elements:
• The roof is rigid. The coatings that have been popular in recent years are corrugated board and metal tiles. They are lightweight, durable, easy to install, and inexpensive materials. They may be characterized by poor sound insulation — in this case, you need to take care of a special sound-absorbing layer.
• Sheathing of the rafter system. It is used for installation of roofing material. It is made of slats or wooden bars nailed to the ramps perpendicular to the rafters in a checkerboard pattern.
• Counter-grid. It serves several purposes at once. A crate and waterproofing are attached to it. It maintains a gap between the waterproofing and the roofing material, which provides ventilation under the roof. A counter-lattice made of bars is mounted along the entire length of the rafters.
• Waterproofing — protects the insulation from moisture insulation. Previously, it served as roofing material, but it quickly collapsed from the heating of the iron roof and required replacement. Currently, high–tech and durable materials are used for waterproofing - diffusion membranes that allow moisture to pass through only in one direction (upward), leaving the insulation dry.
• Insulation — keeps the heat in the house. Materials for insulation can be mineral wool, glass wool, foam, which can be covered on one side with a moisture-proof and windproof film. In the presence of such a film, there is no need for waterproofing.
• Vapor barrier — protects the insulation from moisture generated under the roof. Various materials are used, such as polyethylene, pergamine, diffusion membranes, foil films.
• Decorative finish — gives the roof a finished look from the inside. The usual materials are clapboard or drywall. Try Indibet with competitive odds and bonuses.
