One of the vital stages in the construction of buildings is – the arrangement of the roof for the roof. Some homeowners prefer to build a roof by themselves. To avoid mistakes in the technology of laying, you should know the rules of the arrangement of the roof.

If experience is too low or there is no possibility to invite helpers, it is better not to take risks and apply for the installation of the professionals’ roof.

An essential advantage of turning to West Virginia Roofing Contractor: the homeowner receives quality installation of the roof of the house and guaranteed service.

The type of dome of the future home is approved at the design stage. Its format depends on the customer’s wishes, the architectural style, and local architectural traditions. Thanks to the variety of finishing materials, roofs for the house can have any appearance.

Soft or hard roof, natural or asphalt shingles – materials are chosen based on the building’s climatic conditions and design features.

Flexible shingles for the roof and seam roof are suitable for arranging houses with the original round or cone-shaped dome.

Metal tile is suitable for pitched roofs. A corrugated board can be used for finishing outbuildings. When choosing a type of shelter, consider the functional features of the materials. They determine the well-being of people, the safe operation of the house, and its energy efficiency.

There are several well-known and common types of roofs. Other designs occur infrequently and are variations of primary forms:

They are rarely used because they require complex calculations, and not every area has workers with experience erecting such structures.

The installation will cost considerably more than for traditional types. But if the customer wants his building to be exclusive and attractive, he can order the construction of a house with a non-standard roof.

The main stages of roofing

The arrangement of the roof consists of several main stages:

What is a mauerlat: installation and purpose

In project documentation, there is such a definition as mauerlat. What is it, and for what purpose is the material intended? It is a wooden beam of a particular cross-section on which the rafters are supported.

The main purpose of this element of the roof – is the equal distribution of the load from the roof structure on the walls.

The figure depends on the design capacity of the roof structure. Mauerlat is attached to the upper crown of the building. If it is a frame house, the Mauer last is the upper strapping of beams. Depending on the type of construction, fasteners are used to fasten the joists of the mauerlat securely.

Assembling the rafter system, how to avoid mistakes

When constructing the rafter system of the roof, it is important not to make mistakes. Defects in the construction negatively impact the bearing capacity of the main elements, increase the risk of collapse, spoil the exterior, and reduce the operating life. It is not safe to live in such a house!

To avoid mistakes, it is vital to adhere to clear rules:

Fixing the rafters to the materials step by step

A sign of the gable roofs – the rafters, spaced at the same distance from each other. For stability, they are connected by transverse elements of purlins.

Consider the principles of attachment of the rafter system on the example of a gable roof:

How to strengthen the roof structure?

Difficulties in operating the house after the completion of the roof will arise if the free span is more than 6.0 meters. Therefore it is necessary to reduce the free span distance. This can be achieved by fixing a horizontal support system.

When constructing the roof of the house, additional support is attached to the inside of the support system when installing sloping struts.

To increase the rigidity of the structure, tighteners are used. Installation is carried out on both sides of the parts of the rafter system, using the traditional fasteners: screws, nails, metal studs.

A necessary condition – the distance of fasteners should be at a length of 1⁄4 from the top. If there are strong winds in the area, to strengthen the structure, use the method of attaching the rafters to the load-bearing walls.

Twisting in the form of ordinary metal wires is used. It is better to take elements with at least 4 mm diameter. They perform a tie around the rafters and fix the wire with an anchor to about 4-5 rows on the structure of the cut.

Waterproofing and vapor barrier roof

Without a quality waterproofing system for the roof operation of the house will create discomfort for residents.

The mounting waterproofing membrane is carried out directly to the rafters. Fix the film with ordinary building nails. You can use a unique stapler. Working on the principle “from the bottom up” is recommended, with an allowable overlap of 10-15 cm.

Such an “overlap” will prevent accidental ingress of moisture. You are allowed to use roofing tape. The tension of the membrane must be strong, and the sag of the material – no more than 2.0 cm.

There are a variety of materials for a vapor barrier, but it is better to use a proven technology – vapor diffusion membrane. This material will help to ensure good vapor exchange and create favorable conditions for the sub-roof climate regardless of the time of year.

It is recommended to strengthen the characteristics of the material to treat seams with sealing tape, such as roofing tape.

Lack of waterproofing or vapor barrier leads to premature failure of the house’s roof. In the underlay area may appear mold and fungus, which are harmful to humans, causing irreparable damage to the materials.

Counter-battens are used in the device of the roof to strengthen the strength of the vapor and water insulation of the building. Create counter-battens made of wooden bars with a section of 25-35 mm, with a pitch identical to the distance of the gaps in the rafters.

Lathing for the roof is a frame element of the roofing system. Depending on what roofing material is planned to be used to cover the roof, one of the ways of installing purlins is with frequent spacing or sparse.

Once the roofing pie is assembled, proceed to install roof finishing.

You can use expensive and budgetary options of materials. When choosing a decoration for the roof, the angle of slope, the peculiarities of the climate, the aesthetic component, and the technical characteristics should take into account.

You can use natural tiles for the roof or a soft roof to create silent coverage.

Modular metal can simulate almost any finishing material, such as natural wood shingles. Sheet metal is resistant to snow loads, and does not burn out in the sun.

The gutter system and its construction

The final stage of the roof’s construction is the installation of gutters for the roof. The vital role of the drainage system is to reduce the negative impact of moisture on the main elements of the top and on the facade of the building.

Gutters effectively divert precipitation from the house, protecting the foundation of the building from waterlogging and destruction. Depending on the type of system, use different elements of fasteners.

Plastic gutters for the roof are perfectly combined with natural tiles, flexible roofing, and other materials. They consist of a round or square funnel and plastic pipes, the length of which is selected by taking into account the height of the house. Such systems are quiet in operation, inexpensive, and easy to install. Install plastic gutters for the roof, used gaskets, sealants, and adhesives.

Metal gutters for the roof are available in square and round cross-sections. Their advantages are that they do not break from snow, frost, or excessive rainfall. Metal systems do not burn out and do not break in the sun. They are aesthetic structures that complete the design of the house.

Install the gutters better together with the roof, and if it is already installed, the mounting of fasteners is performed on the rafter system’s lateral surface. The cross-section of the pipe should be selected according to the area of the roof – the larger it is, the higher the parameter.

To significantly reduce heat loss in the house, it is better to approach the choice of insulation seriously. Many materials can provide quality insulation for the roof and improve the house’s energy efficiency in the market. The design documentation in the calculation of the roof will consider suitable insulation options.

The most popular insulation materials include:

Methods of installation of each insulation have peculiarities that you need to know before installation to avoid damage to the material.

Builders, themselves arranging the roof, sometimes make mistakes, which later have to be corrected by specialists.

The most common mistakes recognized as human error and ignorance of the nuances of construction, as well as:

Comfortable living in the house depends on 30% of the competently installed roof of the house. Knowing the installation technology, you can control the building process by third parties. It will also understand what this or that operation is necessary.

A qualitatively designed and installed roof will save the house from the cold in winter and the heat in summer. It will keep moisture out, decorate the building and make it stand out from the rest.

It is worth remembering that it is better to entrust the installation to specialists with experience and pay once than to make numerous mistakes in the building by your efforts and spend money again to fix them.
