How to raise a house roof

One way to increase the living space in the house is a penthouse unit in the attic.Unfortunately, it is not always possible due to the low roof situated.However, this problem too can be solved without resorting to the dismantling work.To do this, just need to know how to raise the roof of the house.If you solve this problem, it is possible to build any room, even the bedroom, even children, even though the study.

preparatory stage of work

Before starting to raise the roof it is necessary to strengthen the base of the roof itself.For this purpose, the most appropriate to apply the metal frame, which is made of channel.Cable-stayed stretch marks should be made of reinforcing rods with a diameter of 14 mm.As a guide rail special support legs will be used to provide an easy upgrade, eliminating the offset to the side.

To attach to the surface of the channel beam, it is necessary to prepare the screws 10 cm in length, 10 mm in diameter.Located in the center of the longitudinal channels directly attached to the beam, they are welded metal ears on the perimeter.Through them the channel will be attached to the beam by means of screws.Practice shows may need at least 70 screws with a diameter of 8 millimeters.U-sections used 2 times smaller, while their strength is sufficient to hold the roof.In addition, their continued use is quite acceptable for the installation of ceiling between the attic and the room of the first floor.Weight channels, which will be used to strengthen the roof at home can be up to 2.3 tons.

How to mount outriggers

Purpose supporting legs - is to ensure easy lifting and avoid bias in the side.The supporting legs can reach a weight of 1.4 tons.It consists of the fact that each of the four feet weighs 350 kg.The height is equal to 2.9 meters and feet are connected to each other by horizontal channel bars 8U brand.The product has a length of 0.385 m. The distance between the horizontal beam channels of support legs is 0.25 m. The spacers 10 brands have used to make the inclined U-sections.When tilted 45 degrees in length is one and a half meters.

If you observe the proposed size, you can get the support legs, which have the necessary strength.Acceptable wind loading for this design is 73 meters per second.These will keep the feet 100-ton roof without any problems.However, before the device is necessary to make the calculations for both horizontal and wind load.Placing the support legs should be in places where there is a main wall in the house or a partition in half standard brick.This will not have to worry about what design can destroy the floor of the first floor.

procedure for lifting the roof

To properly carry out the process of lifting the roof, you need to prepare the tools such as:

• jack with hydraulic drive.
• fittings of metal.
• pillars of reinforced concrete.
• Standard metal strip.
• Nailing.
• Hammer.
• Channel bars.
• screws with the required parameters.

Once the preparatory work is complete, you can begin to raise the roof.For this purpose the hydraulic jack is used which can lift the weight of at least 12 tons.You can take two jacks, but it can lead to poor stability of the structure, while the rise with 2 reference points.In the process of raising the security you need to use a special substrate which is made of a square pipe or channel bars from scrap.Sleepers, located on the pillars should be separated by no less than 25 cm. It is necessary to use 12 transverse rings for each leg.In order to achieve the desired height, space between the cross lay, made of square supports or channels, substrates.

roof of the house is raised not simultaneously but one by one at each corner about 5 centimeters in a single pass.Moving around, and making the alternate rise to different points need height of 25 cm. Cross members are welded to the supports Only after this height is reached.After raising the roof on the 185 cm, parallel to start producing brick masonry for exterior walls.Lifting this height takes at least 3 days.The clutch must be used a reinforcing belt.In the wake of the raising of the entire roof, raised and jack support.Set on the on the same basis on which rests the roof.To make a full attic, the roof should be erected to a height of about 287 cm. You will need about 12 days.All the space between the ceiling and the roof is filled around the perimeter brick walls.

device attic space

After raising the roof and the walls into place, determine the window units in the corresponding openings, the formation of which should be carried out simultaneously with the masonry walls.Insulation of roof space is made after a full installation of the walls.This should provide good protection against the ingress of water from outside.For the attic is necessary to provide good insulation, because the attic has a large area of ​​contact with the external environment.

most commonly used for this mineral wool, which is of a material with excellent thermal insulating qualities of the fibers.Waterproofing is arranged in the insulation not only outside but also inside.That it was necessary to use high-quality special membrane film.Insulation must have good quality as the attic will be used all year round.Loft itself should have a multilayered structure including a vapor barrier, waterproofing, insulation, roofing, and interior decoration.Make sure ventilation should be arranged, which will protect it from mold, mildew and dampness.Between the insulated layer and the roof needs a big gap, which should be the thickness of 2.5 to 5 cm. It depends on the roofing material.

The raised roof can be installed vertical or slanted windows, which are often used for attics.To build a vertical window is much more complicated than inclined, as it requires to construct a truss system for each window.The use of 2 variants has other advantages.Inclined windows allow plenty of light to enter the room.According to regulations, the window should occupy about 12% of the wall surface.

Operation to lift the roof and structures underneath living quarters is a fairly time-consuming process that requires significant material costs and the participation of professional builders.Therefore, the self-realization of these works need to carefully examine the theoretical basis of technology.It is advisable before starting any work to consult with experts.
