If flows ruberoid roofs and patching damaged areas has not brought tangible results, then there is the only right decision - to carry out the complete replacement of the roof, provided that the overlapping of the roof are in good condition.The easiest way to repair a pent roof of roofing material, but the steep roof to block the extension or garage that is adjacent to the house, will, most likely, the case more complicated, but not hopeless.Although the price of roofing and roof repair in the first and in the second case is attractive enough.

Features Ruberoid roofs
roofing material called building the web material, which refers to the waterproofing mater
new modification of this material is self-adhesive roofing material.Its lower part - a self-adhesive layer that is not firmly bonded and covered with a protective film.During operation, the film is rapidly removed to the adhesive composition does not have time to dry out, and press down well to the roof.
Ruberoid gained popularity in the regeneration of the roofs of various buildings because of its advantages, which determine the properties of such material:
- High water resistance - roofing material does not get wet for 72 hours;
- excellent heat resistance - not material swells at 80 degrees for 2 hours;
- high rate of water absorption - the level of moisture absorption roofing material is not more than 2%;
- low deformability - by bending the material at a temperature of 25 degrees cracks are not formed;
- great strength - the basis of modern roofing material reinforced that gives the material increased strength;
- resistance to aggressive chemicals and UV radiation;
- great flexibility - a property of the roofing material retains at very low temperatures;
- low weight of the coating composition - 500 grams per 1 square meter;
- cheapness.Price roofing tar paper, perhaps, the lowest among all roofing materials.
need to repair the roof of roofing material
Today roofing material is most often used as a waterproofing layer of roof pie.Due to its high water-resistant properties of roofing material has been applied on construction sites with a high level of humidity.They also decided to cover the wooden built before installation of roofing.But despite the advantages of roofing material, this material can last no more than 5 years, and at the expiration of this period, it has to be repaired.
Roofing felt is widely used as the top layer of roof pie.But look at it quite unsightly, so often it is chosen as a budget coating material outbuildings, the old village houses and cottages.In this situation, the main enemy of tar board roofing becomes frost, or rather the method of its removal: We decided to do it mechanically, using a steel scraper, which, together with the ice and removes all roofing.
On the flat roofs of multi-storey buildings are often used as roofing material, though it is not intended for waterproofing roofs exploited.But it most often chosen instead of the more appropriate and good material due to cheap, not even trying to find out what to replace roofing material on the roof.In this case, the material more quickly damaged by walking on his staff, for example, the people who control the state of the elevator shafts, installers antennas, advertising structures, or air conditioners.Again, it is necessary to repair the roof of roofing material.
sequence ruberoidnyj roof repair
After spring rains time or before the onset of autumn roof that is covered with roofing material, you must be sure to inspect for defects.If these are found, it is necessary to do the repair of tar board roofing.Methods by which the renovations are dependent on the level of damage and their dimensions.
Removing Ruberoid cracks
roof that does not leak, but covered with small cracks, it should be just dry thoroughly, cleaned of debris and dirt and cover with hot mastic.The consumption of bitumen is about 1.2 kilograms per square meter.
small holes you can eliminate follows.To begin, clean the place of the damage and the area around it from dirt and mastic - a substance with which the roofing material is attached to the roof surface.The smallest holes you can simply zashpatlevat specially prepared putty: mix the heated bitumen mastic dry sawdust and sand.
Mastic to repair the roof of roofing material is more preferable than the heated bitumen, since its formula is complex plasticizers and other additives to improve adhesion and a series of indicators covering in cold weather and in wet weather.
Parapet will prevent the removal of the roof with tar board leaves, twigs and other debris.But in the repair of the roof facing materials from entering this garbage under the carpet of roofing material inevitably provokes a violation of the integrity of the waterproofing mat or air bubbles.
repair small damages
If the area of damage is high, then this area is necessary to impose a patch made from a piece of tar paper.One side of the material should be greased generously with the same mixture.But it may be another complication.In the manufacture of the material ruberoid both its surface is treated with a special grit, which gives it additional strength and inhibiting adhesion of roofing material when stored in rolls.
This is a property of spreading that is to counter the bonding leads to the fact that on the roof ruberoidnyj apply patch is not too easy.Therefore, we first need to remove the surface layer of roofing material.If you do it without a pre-treatment, the need to work hard.
Such treatment is the following: put on tar board roofing brush or brush a layer of solar oil and wait for a while.Then, armed with a spatula should be - it is better to take a wooden tool so as not to damage the lower layers of roofing material, which is a major and scrape posypku cautious movements, which at this point would be soft and pliable.
This ruberoidnyj roof repair can be carried out solely on the dry roofing material, so if you can not wait until the roof is dry naturally as it should, you should use a hairdryer.It is also important to observe the proper technique for applying the adhesive mastic patch.Do not make too thick - it should be smooth and delicate, why not use a stiff brush or brush.
If you have not guessed the amount of mastic, and the edges of the patch when it squeezed out the imposition of excessive weight, then it must be smoothed with a spatula so that it turned out not frozen layer thinner and thicker of the roofing material.
Repair through holes
In more serious defects, such as through-hole, a more thorough renovation Ruberoid roofs.In this case, make an incision crossed on roofing material, and angles that have turned in his heart, peel back the sides, fully exposing the roof.Freed site need a good process: clean of debris and dirt, tear off the old dry paste.
Then you need to adjust the size of the new piece of tar paper, and removing posypku on one side and smeared adhesive composition prepared by the above technology.Such large patches need two.One patch of roofing material paste directly onto the surface of the roof, then lubricate the bent corners of roofing mastic and place them into place, gently stroking.Top
apply a second patch, which should cover even layer of mastic.Treat not only the ruberoidnyj patch, but the surface near her.To the roof of the house does not flake bonded pieces should be pressed boards or bricks, and on top of patches required to sand.
Overlap the roof with roofing material
often requires a complete renovation Ruberoid roofs, that is to remove old coatings and installation of new roofing.Remember that using tar paper can be repaired only Ruberoid roofs or old shingle roof.
Before build a new roofing material on the roof, it is necessary to dismantle the old stuff, who lost their properties to the base of the encircling, or has a lot of mechanical damage and bundles.Also the roof is necessary to remove all dust and dirt.
Very often in such work, a resin which is glued strips of roofing material.Under the influence of environmental factors over time begins to crack resin.If it is not removed, the cracks soon begin to accumulate water.So you should carefully remove all the tar on the roof under the roofing material.
If your building's sloped roof, then you should arrange before laying a solid roofing lath.To do this, use the edging made and edged boards, DSP and OSB boards and plywood.If a pitched roof and roofing material was blocked before, you should check the existing crate for decay, mold or mildew, remove the detected defects or clean up local areas and to cover special impregnation.
If the overlap was used reinforced concrete slab, the roof should be cleaned up concrete.On the basis there should be no large bumps and potholes.All excavation should be sealed polymer mixture.In the case of significant irregularities on the basis of need to make sure the weather is dry screed do with a bias towards the drain, which is created by increasing the thickness of the screed one centimeter per meter.To do this, use the normal water level or laser.
when he grabbed the concrete, you need a broom to sweep away all the garbage and brush or roller applied mastic.Remember that to work with mastic screed and all ruberoidnyj material is not suitable rain.On wet surfaces is not necessary to carry out any action that will happen because peeling material.Choose a clear, warm and sunny day.
Mastic is different composition, so you should look at the label during its "setting" and conditions of use (temperature and humidity).Do not rush to cover the roof with roofing material, you need to be sure to dry the applied wax and some grabbed the surface.
to work with roofing material you did not deliver a hassle, it should stand for days in the unfolded state.If it fails to do, just rewind the roll in the opposite direction.Before laying roofing material must be pre-cut pieces of roofing material to the desired size.
After the mastic dried, you can begin the process of laying of roofing material.It lay at least two layers of roofing tar paper.You have to use for the first layer prostilochny ruberoidnyj material without crumbs, and to create a second - coating with stone chips.The required number of layers will depend on the degree of slope of your roof.
on flat roofs is recommended to do at least 5 layers.If the roof slope up to 15 degrees - paved layer 4, if the angle of 20-40 degrees roof - make 3 layers, if the slope of 45 degrees and above - enough 2 coats.There are 3 methods of stacking panels, let's consider them:
- placement of panels across the line of slope.In this situation, it is recommended to begin the work from the eaves, and make sure that each row went to the previous overlapping 10 centimeters.Water seams will not be guaranteed to fall.
- Surface Ruberoid material along the slope.The water in this case will flow along the cloth and can not flow under the seams.Side overlap also make about 10 centimeters.Work carried out on the pediment overlaps and make the leeward side to the prevailing wind does not bullied delaminated coating.
- Using the first two methods of installation.The bottom layer is laid on the first method, the top - by the second, and vice versa.
If you choose the first or second method of overlapping roof with roofing material, the flooring material so that the seams do not coincide layers.On pitched roofs are most commonly used flooring panels across the slope, as in this case, you can throw a horse through a piece of roofing material, hook up, and then - at the bottom.
Bonding For bonding of roofing material to the base requires a gas burner with which the roofing material is heated, together with mastic.Positions on the sheet of material is heated up until the top film turns white and does not burn.This signal indicates that roofing and mastic ready for bonding.
heated strip should be well pressed to the roof, gently smooth the ride and special hand roller adhesion to quality.If there are irregularities, should be fit by hand to achieve a quality of the cloth to the roof surface.You can do a normal cloth.Do this - section by section.
If the surface having deep potholes qualitatively roller to roll such a surface, you can not.As a result, in those places with time will occur condensate, which provoke damage to the roof.So once again remind you that before the installation of roofing surface should be carefully prepared.
If you can not avoid irregularities, roofing felt in such problem areas should be pressed to the roof by any means available.It is generally recommended to strictly implement, since the material must fit snugly to the base.
It is recommended to carefully monitor the heating procedure.If you warm up very much, Ruberoid material may melt.Therefore, before you repair the roof of roofing material directly glued panel, costs a little "train" into small pieces.Keep in mind that the adhesion to the second layer can start only after the first completely hardens.
to provide insulation roofing pie vertical elements, for example, pipes, shafts, chimneys, we recommend waterproofing carpet factory on them to a height of nearly 40 centimeters.After attaching a further press of special clamping plate that is attached to the base of a good parapet.
Places drain boxes and other components that require a cut of roofing material, you need to further strengthen the flaps of material ruberoid in 2 - 3 layers on top of the notch.It is very important to stick to the edge of the roof sheets, or tear the cloth wind.To ensure greater reliability, cost to fix roofing material at the edge of the roof with wooden or metal rods.
Now you know how much new roof with roofing material, and how to repair the roof with the help of this material.The procedure for the roof decking roofing material ruberoid poses little difficulty even for exceptional builder.If you correctly perform all phases of work, the roof will get a trim elegant look, cover will last "faithfully" for many years, and you will not even know that such a roof leak.
