Do-it-yourself garage roof repair with bikrost

In detail: do-it-yourself garage roof repair with bikrost from a real master for the site my.housecope.com.

Violation of the integrity of the roofing of the garage sooner or later turns into leaks, serious destruction of the materials of the roofing, the appearance of dampness and mold inside the room. Ultimately, the vehicle and other property stored in the garage may be damaged. In order to repair the garage roof with your own hands to give the desired result, you need to choose the optimal work technology.

At the preparatory stage, you should carefully examine the surface of the roof. Based on the type of damage, the following measures are taken:

local repair (individual damage is eliminated);
restoration of the coating (filling numerous small cracks with bitumen material over the entire surface area or laying a new outer layer);
overhaul (replacement of the entire roofing cake with its high degree of wear).

Before starting repair work, it is important to thoroughly clean the roof surface of debris and dirt, dry well... Roof repairs should be scheduled for dry, warm, but not hot weather.

Local damage to the roofing carpet of flat garage roofs includes:

individual cracks;
swelling of the coating;
breaks on the surface of the coating;
delamination at seams, etc.

Damaged areas must be thoroughly cleaned of dirt and dried... For this purpose, the places of rupture are opened with a cruciform incision ("envelope"), the cracks widen. Small damaged areas can also be cut out with an ax, making a rectangular "window" to a depth of 3-4 layers of roofing carpet.

For local repair of a roof made of roofing material or materials to be welded, bitumen is used, which requires heating, or ready-made cold mastic, as well as a material similar to the top layer of the coating.

Cold bitumen mastic for local repairs is most suitable for filling deep cracks and minor damage. It can also be used to apply patches. Heated bitumen resin is poured into any damaged areas, including cracks and cut through "windows", while it is important to ensure that the resin penetrates into the most distant and hard-to-reach areas.

In order to repair the damaged area, opened by the "envelope", it is necessary to use patches. The first of them is cut to the size of the "envelope" and placed inside on the base, well coated with bitumen. The bent edges of the coating must also be thoroughly coated with bitumen and pressed tightly to the surface. The outer patch should extend beyond the edges of the area to be repaired by 150-200 mm. It is laid on a layer of bituminous mastic or heated resin and smoothed tightly.

The bulges of the outer covering must be cut, let out air, smeared with mastic and pressed firmly. Seams that have lost their tightness are cleaned of old mastic, dried, re-glued with bituminous material.

If the surface of the repaired area is covered with bitumen, it is recommended to pour a layer of sand on top to protect the bitumen material from ultraviolet radiation. UV radiation makes the bitumen brittle, which shortens the life of the repaired roof.

A flat garage roof covered with an affordable roofing felt requires regular inspection, even if there are no leaks. This material ages over time and can become covered with a network of shallow cracks. To prevent more serious damage, it is required to create a high-quality waterproofing top layer of the roofing carpet..

In order to extend the life of the roof carpet for several years without significant financial costs, it is recommended to seal cracks with bitumen resin. The technology of work is quite simple: the heated resin is poured onto the roof surface and leveled using suitable tools. The bituminous material fills in micro-cracks and creates a waterproof coating.

A more durable and functional finish can be achieved with a cold applied bitumen mastic. This material is a refined petroleum bitumen with various additives that increase the strength and elasticity of the material, reduce brittleness, and ensure the resistance of the coating to temperature extremes.

Such an insulating material will reliably protect the roof from moisture and subsequent biological destruction of the underlays of the roofing carpet. When repairing with mastic, the surface must be clean and dry. The working composition of cold application is leveled with a brush or spatula. After drying, a layer of mastic turns into a strong, durable coating, completely impervious to moisture.

If the roofing carpet is in good enough condition, but the outer layer has undergone serious wear and tear, it is sufficient to install a new outer decking for a quality repair. First, it is necessary to eliminate all existing local damage by filling the gaps and cracks with bitumen mastic, removing the bulges. It is important to clean the surface with high quality, removing old mastic and dirt, as well as dry the coating well..

Classic roofing felt or weld-on roofing material can be used as an external coating. It is much easier to repair the garage roof with Bikrost or other roll-on weldable material, since you do not need to use molten resin, but in this case, the financial costs for repairs are noticeably higher.

Roofing material is installed on a layer of tar (molten bitumen). The resin needs to be heated over an open fire in a tin bucket to the consistency of thick sour cream. The rolled material must be rolled out at least a day before laying so that it straightens out - this will simplify installation and significantly reduce the likelihood of air bubbles.

Sections of the roof are covered with resin as work progresses with the roll material. Roofing material strips are required to be mounted with an overlap of 100-150 mm, carefully coating the joint with resin.

During installation, air bubbles may appear under the already installed cover. In these places, it is required to make an incision with a knife, press the material tightly to the base, and then coat the incision well with bitumen. Using roofing material, you can create a high-quality waterproof canvas that can reliably protect the garage. If the covering is installed over an old roofing cake, it is sufficient to lay it in one layer.

Fusion-bonded roll roofing is laid using a gas burner. On the back of the material there is a special layer of oxidized bitumen. When heated, it quickly and efficiently adheres to the prepared base.

At the beginning of work, the roll should be carefully rolled out to 500-600 mm. Warm up the wrong side with a gas burner, and then press the material to the surface with a T-shaped stick. Then the roll is rolled out another half meter and the operation is repeated. The next strip is mounted with an overlap of 70-80 mm over the first one.

The weak point of the garage roof is the joints of the roof with the neighboring ones. It is at these joints that material delamination, cracks and ruptures primarily occur. During repairs, special attention should be paid to these edges of the coating.

When overhauling the roof, the old roofing carpet must be completely removed from the garage roof.The base of the roof is cleaned of debris and, if necessary, leveled with a screed. The roof carpet of a flat roof of a garage should consist of five layers, made of roll materials.

The lining layers are mounted from a non-covering material (lining roofing material, glassine) - there is no protective dressing on its outer side, which ensures the most dense and reliable adhesion of the layers.

For the installation of the top layer, a cover material is mandatory, equipped with an outer layer of refractory bitumen with a dressing that provides protection against mechanical damage and ultraviolet radiation. The dressing can be coarse, fine or dusty.

The installation technology of the roofing carpet is selected based on the characteristics of the materials used. This can be laid on molten bitumen or using a gas burner. It is important to install the strips of the covering of the upper layers with a shift relative to the lower so that the joints do not coincide - this guarantees the creation of a reliable waterproof roof covering.

Before installing the roofing carpet, the base of the garage roof must be treated with tar, heated bitumen or a mixture of these. This will ensure high adhesion of the roofing material and increase the reliability of the coating.

You can repair the garage roof alone, but it is recommended to work with a partner, especially when it comes to laying roofing material on tar. In addition, safety rules should be followed as:

an open flame is used to prepare the resin and when working with a gas burner;
work is carried out at a height of about two meters - falling from it is fraught with fractures, including life-threatening ones.

In order for the repaired roofing to last as long as possible, it is important to strictly adhere to the work technology and use high-quality materials.

Professional roofing renovations are expensive. It is quite possible to make repairs to the garage roof with your own hands with minimal cash costs. Rarely, when you need to cover the entire roof, you usually need redecorating, which is inexpensive.

Soft roof covering, which is most often used for a garage: roofing material, bituminous shingles, roofing material Euro or bikrost.

You will need several rolls of roofing felt or bitumen shingles and other materials and tools:

bituminous mastic for roofing material or resin;
tar, if you need a complete replacement of the old coating;
gas burner or hair dryer;
sharp knife.

It is better to take roofing material for repairs with some margin, since you will need to make patches in several layers.

First, the entire roof must be cleaned of debris in order to see all defects and damage. We especially thoroughly clean the damaged areas.

To ensure the best adhesion of materials, it is necessary to properly prepare the roof for repair:

the place where the roofing material is damaged, cut it crosswise with a knife and bend the edges of the material outward;
we clean out all dirt and dust and dry the surface with a construction hairdryer, a gas burner is also suitable for drying;
if a sheet of roofing material is badly damaged, then it is better to completely replace it, the masters advise not to patch the roof in small pieces, but to lay a new sheet of covering. Over time, under the influence of rain and wind, the repaired place will crack, and the repair will have to be carried out again.

Important. Several layers of roofing material are laid in such a way that the joints do not coincide. This will prevent moisture damage.

Repair should be carried out in warm, dry weather, the temperature is above ten degrees.

After the place of damage has been cleaned and prepared, we start repairing the roof:

cut out squares of roofing material according to the size of the prepared patches;
Lubricate the holes in the coating with mastic or resin and apply a patch;
it is important that the mastic or resin fills all the voids;
press the patch;
on top, once again apply a layer of mastic and close the previously bent edges of the patch, tightly pressing the edges to the adhesive base;
apply another layer of mastic;
it is very important that there are no voids and gaps left through which water will penetrate. Therefore, on top of the repaired area, you need to similarly glue another piece of roofing material of a larger size (the upper patch should overlap the lower patch on all sides by 15 centimeters).

Such partial repairs are not suitable for an old, dilapidated roof; the entire roof must be replaced.

Repairing a garage roof with roofing felt is an inexpensive but tedious process:

before laying, you need to let the material lie down and level out, this will take a day;
we begin the installation of roofing material from the lowest point of the pitched roof;
first, it is necessary to apply a layer of tar, on which we lay strips of roofing material;
we perform the actions in stages - we applied tar, glued the strip;
cover strips are laid with an overlap of 10 - 15 centimeters;
along the edges of the strip, we must insulate the joints with molten bitumen;
if the base is uneven and bubbles have formed, then they must be carefully trimmed with a knife and smoothed. It is imperative to apply a layer of tar on top of the cut;
depending on the slope of the garage roof, it is necessary to choose the number of layers of roofing material: a slope of up to 15 degrees - four layers, a slope of up to 40 degrees - three layers, a slope of more than 45 degrees - two layers of coating.

Advice. We lay out the bottom layer with tar paper or fine-grained roofing material, and for the top layer only coarse-grained roofing material is suitable, it is more durable.

Covering a garage roof with bikrost is simple, fast and inexpensive. Bikrost can patch holes in the roof quickly and easily with a gas burner. The sequence of repair with bikrost and installation is as follows:

we clean and prime the entire old roof surface;
roll out a roll of bikrost by 50 cm and heat it up with a gas burner. Pay particular attention to the edges and corners of the tape;
we press the heated sheet to the roof. It is convenient to use for firm pressing with a mop stick (like the letter T) or a heavy roller;
sequentially heat 50 cm of bikrost and similarly glue it to the roof;
the overlap of the strips of material should be at least 8 cm.

Bikrost is much more convenient and stronger than roofing roofing material, but you need to work quickly, the material hardens quickly. It is better to work with a partner - one rolls out and presses, the other heats the material with a torch.

Important. Do not walk on the surface that has just been laid, as the tightness can be broken and the roof will be uneven.

Liquid rubber can also be sprayed onto corrugated board, this will reduce corrosion and provide good waterproofing of the roof.

Polyurethane roofing mastic, popularly known as “liquid rubber”, is a miracle material that is a pleasure to work with.

In terms of density, viscosity and consistency, the composition is similar to water, so you can safely cover the entire cleaned surface of the roof from an airless spray under pressure. A conventional spray can not be used. After polymerization, liquid rubber forms a dense and durable hermetic film.

Such a coating has no seams, is completely monolithic and hermetically sealed, there are practically no leaks of the coating for 20 years.

Covering the entire roof with liquid rubber is simple:

we clean the surface, dry and prime;
on the primer, you need to lay a layer of geotextile on all abutments and joints of the roof, special attention to the corners;
geotextiles must be installed inside and out;
the composition is applied from a special machine - a two-channel spray.

The coating hardens in a couple of minutes after application.

Popular hard coverings are corrugated board and slate, less often roofing iron is used for the roof of the garage. Most often, a leak is found in a rigid roof in the area of \ u200b \ u200bthe ridge and at the joints of the sheets.You just need to replace the damaged coating sheets with new ones. This will require simple tools:

ordinary screwdriver;

self-tapping screws for metal for corrugated board, it is better to take self-tapping screws with wide caps and fasten them using waterproofing mastic (a tube will be enough for work);

jigsaw and tape measure;

sheets of corrugated board (quantity as required).

Roof repair from roofing corrugated board, sequence:

dismantle damaged sheets;

we inspect the wooden parts of the rafters, if they are rotten, then they must be replaced with new ones. If the mold has just appeared, then you can clean the rafters with a plane and treat the place damaged by mold with deep penetration impregnation (antiseptic and water-repellent for wood);

check the waterproofing layer and, if necessary, replace the damaged piece with a new one. It is necessary to lay the waterproofing in place with an overlap of about 10 cm, not less;

replacing the sheets of corrugated board, the rule must be observed - overlap the adjacent sheet by one wave - this will provide high-quality waterproofing;

the sheet is mounted on self-tapping screws with a pitch of 50 - 60 cm, the joints are additionally sealed.

Advice. Painted corrugated board is more durable. You can also cover the sheets yourself with water-repellent paint from a spray gun, this will ensure the metal is resistant to corrosion. Image - Do-it-yourself garage roof repair with bikrost

If several sheets are cracked, then do not rush to completely change the entire sheet. Minor damage to the slate can be repaired with a simple, inexpensive mixture.

For the repair mortar, you need cement, asbestos chips (you can finely grind a piece of slate) and PVA glue. We mix the components, you should get a mixture, the density of good sour cream.

We quickly putty cracks and chips - the solution hardens very quickly. Therefore, it is better to work in dry cloudy weather or in the evening, so that there is no direct sunlight.

To repair slate, you can use special adhesive tape (for outdoor use) or slate mastic, but this will cost more.

If the cracks in the sheets are too large, then you can put patches of sheet copper, it bends easily and does not corrode.

It is better to carry out such a roof repair together, since the sheets are heavy. First, we dismantle the old sheet, removing all the slate nails with a nail puller. Further work is simple:

we lay a layer of roofing material;
we lay a new sheet of slate;
the overlap of the sheets should be in the direction of the wind, which is most often the case in your area;
we fix the sheet with slate nails. You need to drive nails into the wave to avoid cracks.

Important. Under the nails, so that there are no leaks, you can make homemade rubber gaskets. This will keep the sheet from cracking and serve as an additional seal.

Among the types of soft roofing for roofs with a low angle of inclination, bikrost deserves special attention. This is an excellent protection of the roof from moisture, successfully combining excellent quality and a fairly reasonable price.

Bikrost is a weldable material that is used for waterproofing a roof. It is based on fiberglass impregnated with high quality binders based on glued bitumen. The structure of the bikrost is absolutely in line with modern requirements, so it can also be used on visible parts of the roof.According to the laying technique, an open fire is required to melt the coating of the inner layer. Therefore, it can only be laid on a surface made of non-combustible materials. Preparation of the base Before starting work, you need to achieve maximum hardness, evenness and dryness of the working surface. For this, the roof plane:

clean from dirt, dust and foreign objects, remnants of the old coating,

seal cracks and grooves with putty or cement mortar,

ensure the absence of moisture.

For better adhesion, the surface is additionally treated with a primer, which is applied with a roller or brush. It can be a finished product or bitumen diluted in kerosene or gasoline (ratio 1: 3).To cover the roof with bikrost, you must wait until the primer is completely dry. To check, it is enough to run over the surface with a dry cloth. If the surface is dry, there should be no marks left on the rag. Image - Do-it-yourself garage roof repair with bikrost

Features of laying bikrost on the roof

Bikrost is recommended for use in structures with a slight slope of the roof, and with an angle of inclination of less than 15 °, laying is carried out perpendicular to the slope, and with a larger one, a parallel arrangement is recommended.
When installing a new roof covering, it is laid in two layers. First, a material is used that is covered with a polymer film on both sides, for example, the HPP brand, and for the second, external one, sheets with coarse-grained dressing, for example, the HKP brand.
It is recommended to lay the rolls by fusing with a gas burner. In some cases, it is glued with bituminous mastics;
Adjacent sheets of coating are placed with an overlap of at least 10 cm in order to ensure the reliability of waterproofing at the joints.

Work on laying rolled bituminous materials is a relatively simple process, it can be done with your own hands. Some general knowledge of construction is required, as well as skills in working with a gas burner.

Immediately before laying, the existing material is tried on to the installation site and the sheets are sized to the required size. That is, the material is rolled out over the surface and cut out according to the configuration of the base, after which the web is rolled back into a roll.
Turn on the burner and at the same time evenly heat both the base of the roof and the bottom layer. The main thing is not to overheat the base of the canvas, so as not to damage it.
The roll is rolled out from itself in such a way that only the heated areas are combined. The molten bitumen will immediately fix the laid part. You can roll this section with a roller with movements from the center towards the edges.
Since dents or cuts are easily left on a fresh roof, you cannot walk on it. The roll is rolled out with a metal or wooden hook.

The technology of laying bikrost in places where it adjoins vertical surfaces requires special attention. The resulting joints must be carefully glued.

To do this, cut out small pieces and weld them onto the vertical part, and then onto the horizontal one. It would be better to treat these areas in two layers.

After completing the laying of the first layer, the installation of the second row begins. The finishing layer is laid with bikrost with coarse dressing - it will protect the surface from mechanical stress and from sunlight.
More experienced craftsmen can cover the roof with material without overlap - just butt-to-end. In this case, it is especially important to observe the tightness of the joints.

The air temperature during installation work on laying the bikrost roof should exceed 5 ° C. If it is necessary to organize work at a lower temperature, the material is kept for 24 hours at room temperature.
The sloped roof is laid from the bottom up. This eliminates the likelihood of leaks in the joint areas of the canvases.

When choosing a material for a roof, it should be borne in mind that the service life of bikrost coatings is 5–8 years. When calculating the required amount of material, it is also necessary to provide for a margin for the joints of the canvases.

Watch the video on how to properly fuse bikrost.

Most often, garages and other outbuildings are built with a flat roof, which has a slight slope, no more than 20 degrees. The best option for covering such roofs is the Bikrost roll roof, which is described in more detail below. You can read an overview of the characteristics of a cinder block garage foundation here.

The picture shows the rolls of the Bikrost roof

Bikrost is a special building material that is used to waterproof the roof. It consists of a fiberglass impregnated with binders, based on lined bitumen.Its characteristics correspond to the highest quality requirements, and therefore, its use is not limited only to waterproofing, it is quite possible to cover the roof with it in the visible part. Read the guide on how to calculate the foundation for a garage on this page.

Bikrost has a number of advantages:

Durable material
Not subject to decay
The presence of top dressing protects the canvas from exposure to ultraviolet rays
Can be used as a vapor barrier
Resistant to various weather influences, due to which it is successfully used in any climatic zone of the country
The ratio of excellent quality and affordable price

Before covering the roof with Bikrost, prepare the surface, since the material is soft and demanding on the quality of the base:

The substrate must be dry;
Complete absence of various irregularities;
The roof surface must be cleaned from dust and dirt, as well as any foreign objects;
Even the smallest cracks and dents must be repaired with cement mortar or putty;
Then treat the surface with a primer (primer) for the best adhesion to Bikrost.

The process of covering the roof of a garage with Bikrost itself is as follows:

Rolls are laid out across the slope, keeping an overlap of at least 8 cm;
All work is carried out strictly from the bottom up;
From the end part of the rolls, the overlap is observed from 15 cm;
The ends of different rolls should not form a single joint line, so they should be displaced relative to each other;
The required length from the roll is rolled out, here the overlap is taken into account;
Then the segment is rolled from both sides to the middle, heated with a gas burner and rolled to the working surface;
The rolling process itself takes place from the middle to the end, on each side. Attention! It is impossible to walk on a freshly melted and rolled roof, since the integrity of the coating is violated, as a result of which the waterproofing;
During rolling, it is necessary to ensure that there are no folds and wrinkles;
When rolling out the first layer, you should immediately take care of covering the abutments. To do this, a small piece of 40 cm is cut from the bottom layer of Bikrost, of which 25 cm will go to cover the vertical surface, the rest - to cover the vertical surface.

The video shows a step-by-step scheme for covering the roof with Bikrost rolled waterproofing material:

In the photo, the roof of the garage, covered with BikrostThe process of repairing a garage roof using BikrostBikrost laying process in the pictureTo ensure excellent waterproofing of the garage roof, when covering with Bikrost, special attention is paid to the joints of the ends of the rolls. The overlap in this case should not be less than 10 cm. Only if this recommendation is observed, the garage roof will be perfectly protected from moisture ingress. Instructions on how to make electrical wiring in the garage here:Roll roofing material Bikrost can perfectly protect the roof from moisture and it is used not only as a new roof covering, but also during renovation work, laying on the old covering. Before starting repair work, you should also prepare the surface, clean it from dirt and irregularities. If the old coating creates a lot of interference, and it is difficult to level it, then it should be completely removed, or as much as possible until the surface becomes as flat as possible. Further, the technology of repairing the roof of the garage is fully consistent with the technology of roofing Bikrostom, which is described above. Read on for an overview of the characteristics of a garage slab foundation.See recommendations for repairing the roof of a garage by Bikrost in the video:

As can be seen from the above, Bikrost is a high quality material that can waterproof the garage roof well, as well as serve as an external coating for it. The affordable price for roll roofing of this quality is acceptable, which makes this material even more popular. And the installation of Bikrost will not be difficult, even for a beginner.

There are several technologies for repairing a garage roof with your own hands. The choice of a specific method for carrying out restoration work depends on the level of wear of the roof, its type and directly on the type of motorhome.

The restoration of the roofing of a house for a car is currently carried out using three main technologies: soft materials, hot bitumen, tiles or profiled sheets. Private garages are mostly covered with inexpensive and at the same time durable materials - modern ondulin and flexible tiles, corrugated board. You can easily select the optimal method for "treating" the roof of an RV based on the type of roof covering.

Regardless of the technology chosen, you will need to properly prepare the roof for repairs. Inspect the roof, establish the level of its operational wear, determine the roofing elements that must be replaced without fail. In cases where the old coating as a whole is still quite suitable, remove only problem areas by cutting them out with an ax. Subsequently, they can be replaced with new elements, significantly reducing the cost of repair work.

Roof preparation for repairs

If the covering was made with roofing material or a similar material (equipped with a soft roof), swelling and cracks often appear on it over time. Such problem areas need to be dealt with even before the start of repair activities. It is not difficult to do this: cut the defective areas crosswise with a well-sharpened knife; Bend the resulting triangles and clean out debris and dust from them.

When carrying out repairs, such areas with corrected flaws you will need to fill with bitumen. Below we will tell you more about how to correctly perform such an operation. Thoroughly clean the roof surface, rinse with water if necessary. Now you can start recovery activities.
