Wooden roof - repair, installation , insulation

assembling wooden roof, as a rule, is carried out with the use of milled boards a maximum thickness of 2-2.5 cm. Pre on the surface doing a designed for water drainage shallow grooves.

If necessary, replace only one board, rotten due to gapping cover elements and the penetration of moisture into the cracks, damaged board should be carefully removed and in its place attach a new, carefully watching the laying step.

Professional Roofers against fixes such damage by means of a patch cut from the board.The service life of such inserts is very short, and after a short time again have to carry out repair work on the roof.

rotten rafters must be replaced completely, removing the old and new fixing bars.It is important to make sure that the new sticks closely match the desired size and plugged into the slots at the ends of cuttings are rafters.

roof, sagging due to rotting podstropilnyh bars, before the repair work should be leveled with a jack.It is possible for the same purpose and use rack with wedges.Then, under the rafters sum struts, connecting them with braces on the rafters.The final stage is the replacement of the damaged bar.

If it is impossible to replace podstropilny bar completely, can consolidate his wooden plates, which are connected by bolts with a damaged board.

to timely detect coating defects, periodically need to check the status of components attic space hardwood floors.This is accomplished using a conventional ax, tapping the butt girders.Deaf sounds coming after the impact indicates the presence of damage to the roof element and the urgent need to fix.

most common defect attic floor is all rotting beams fastened in the walls.To prevent further spread of rot, should be treated in advance using an antiseptic solution of the board or bar to strengthen the damaged beam.

cross-section of such a lining must coincide with the cross had come to the unsuitability of the beam and the length should be equal to twice the length of the element.

usually cover made from laminated or solid softwood and cranial bars - from aspen and alder.

main features of the installation of wooden roof

Dimensions new cranial bars, which are patterns of sawn timber blanks should be the same size of the old ones.By their beam is attached with nails, having a length of 10 cm and a diameter -. 0.4 cm to hammer nails, having them strictly in the middle of the bar.In the process, it is important to make sure that the nail necessarily entered into the beam.

variety of roof damage often provoke damage to boards and slabs.In most cases, you need to completely replace the cover, to correct such defects.The sequence of execution of these works is as follows: first of all removed warming layer, panels and boards, then removed the rotten beams, cleaning them from dust and dirt.At the final stage of examining beams, checking horizontal support and a breakdown of the axes.

Then the old beams are replaced with new, treating them with an antiseptic solution (bitumen or tar) and wrap the ends with roofing felt or tar paper.In case poorly allowed to dry wooden beams, do not plug the slots by securing them in place.To avoid damage to the material after drying is recommended to leave them open.

The frame and panel buildings beams attached to the upper trim of the walls, the wooden log cabins - on the outer walls, with bars like a cut in between the upper rims.

During the construction of brick houses beams are placed, be sure to strengthening them in the outer walls at a depth of 19-20 cm from the wall at intervals of 3 cm. Cement is necessary to cover the joints.The ends of the beams should be cut at the same time "NAIC" to between a wall and a beam formed airbag, contributes to a better evaporation of moisture from the ends.In operation first extreme fixed beams, and then verify their location and put the rest necessarily parallel.With horizontal level check, and then fastened with nails stacked beams, and then put them on the ceiling panels, covering them with a layer of roofing felt or tar paper and finally the insulating material.

When correcting damage to the panel overlap should first assemble the frame, and then attach them to the plate with nails and glue.This is followed by the end of the handle bar with an antiseptic solution and put roofing felt or roofing material in the wall at the point of attachment of the future, attaching it with the mastic asphalt.Then, positioning parallel to each other, secure the panel, joining them together with nails hammered on special inserts designed to mask the joints.The final stage involves the installation of a wooden roof coating layer of insulation panels, with both new and old.

As the insulation in the chopped wooden houses can be used boiler slag or coal slag.In their overlapping poured layer of 10-15 cm, and the perimeter - a layer having a thickness of 30-40 cm and a width of 1 m Coal slag must be dried before use, maintaining the air until complete disappearance of sulfur smell..Boiler slag periodically need to moisturize.

wood roofs often affects beetle-grinder.The result of his invasion are numerous small holes in the wooden elements, greatly reducing the life of the roof.An effective method of dealing with the bug - Processing of constructional elements of the surface with an antiseptic solution.With the same purpose can be used acetone and nitro.

in complete disrepair wooden roof come because of the appearance of the fungus on the surface.In this case, the best solution would be an antiseptic, prepared from 950 g of sodium chloride and 50 g of boric acid.Boric acid and salt are mixed, and then 5 l of boiling water is poured.

surface of wooden parts roofing wipe the resulting solution at least 4-5 times to completely destroy the fungus.
