In this article, we will consider an important question about how to work with a waterproofing for a roof.

Recently, people often, for the sake of economy, try to do the feasible work themselves.

Since the material is relatively new, not everyone knows how to cover a roof with a waterproofing.

Therefore, we recommend that you familiarize yourself with the following material.

main characteristics and advantages

material First of all, the flashing is a material that prevents the roof fromit is one of the most important aspects for the roof to serve for more than a decade.

Waterproofing is a material that consists of glass wool or fiberglass. Therefore, he does not have such troubles as decay and decomposition.

More often it is a roll-type material, a polymer-bitumen composition is applied on both sides. This makes it sufficiently flexible and not subject to cracking.

There are varieties of waterproofing, which are based on paper or cardboard. Sometimes a liquid waterproof is used, it is available in the form of bitumen mastic.

As a rule, it is used to prevent corrosion of building structures.

Couples to the roof surface by melting the bottom of the material or using a mastic.

In addition to insulation of the roof, it is also often used when laying a foundation, walls in basements, various ceilings, in pools and pipelines.

Depending on the purpose it can be divided into two types: roofing and waterproofing.

The main advantages of the waterproofing are:

• simple laying and operation;
• flexibility;
• water resistance;
• durability.

Waterproofing can be applied on the following types of surfaces:

• concrete;
• wooden;
• roofing;
• metal, etc.

Material specification:

• With tension, the force at which a rupture occurs can range from 37 to 60 kgf;
• Absolute hydrophobicity;
• Elasticity;
• The brittleness temperature of the upper layer material is 15 degrees;
• It is able to withstand a temperature of +85 degrees for two hours;
• The minimum service life is 15 years.

The characteristics of the liquid waterproof are slightly different:

• Withstands the temperature to 100 degrees;
• Hygroscopicity is 0.2%;
• Dry residue - 65%;
• Completely dries from 15 hours to two days;
• The density is 0.9 g / cm³;
• Can serve more than 30 years.
• It is often enough hydroisol, which is used in the work on the roof, called hydroglass.

Tools required for working with waterproofing:

1. building hair dryer;
2. gas burner;
3. blowtorch.

The choice of waterproofing as a roofing material is fully justified, since this material has a mass of positive qualities, it can serve you for several decades.

The price of waterproofing varies from 400 to 700 rubles per roll. The cost of the material depends on the thickness, the length of the roll.

The width is generally the same, but sometimes varies slightly. But the thickness and length already depend on the type of waterproofing and the purposes for which it is intended.

Preliminary preparation of

So, let's say, you want to cover the roof of your garage with a waterproof by your own hands. In order to do this correctly, pay attention to the following points.

Any roofing work, no matter the roof of the garage or at home, requires preliminary preparation, read our recommendations, and for clarity you can use the video.

First you need to clean the base of the roof of all accumulated dust and dirt.

Then eliminate any irregularities, defects and chips with the help of putty, plaster or bituminous materials( depending on the type of roof on your garage).

The next step is to apply a primer layer to the roof surface. This may be a primer or bitumen. Note that the bitumen will need to be diluted with gasoline, make a liquid product from it.

We distribute this primer over the roof surface using a construction roller.

Laying roofing material

The process of laying the waterproof can seem quite laborious and, perhaps, so it is.

There are three ways of laying the surface of the garage roof, below they are all considered in detail. In order to present the process more clearly, we recommend that you familiarize yourself with the video.

Mechanical laying

This is the easiest way to lay a waterproof, but at the same time, the most unreliable. It is necessary to roll rolls with an allowance, which should be at least 15 centimeters.

This technique will allow you to cover the roof with a slope, which will allow the water to flow unhindered from it. You should start from the edge below and gradually rise higher and higher.

At the end of the installation, the joints should be bonded with resin or mastic.

Hot way

You need to slowly start rolling the roll on the roof, and at the same time, warm up its lower layer with a gas burner or a building hair dryer.

Due to heating, the bituminous layer will permanently fix with the litter surface.

The downside of this method is that it is the most inconvenient for stacking your own hands, since one can cope with almost impossible.

After the first roll was laid, proceed to the second one, at the same time it is necessary to make a 100 mm clearance for the material that has already been rolled out - this will ensure a strong adhesion to the two layers of the waterproofing.

Remember! Do not overheat, as this will damage the material!

Laying on bituminous paper

Apply a layer of mastic to the roof surface, which will slightly extend beyond the edges of the roll. Then we put a roll on the mastic and bond it well with the roof using a roller.

With this method of laying you will have to spend money on mastic, but you do not need a gas burner.

Now we have figured out what methods of laying waterproofing exist, you just have to choose which one suits you best.

For the roof of the house is usually advised hot way of laying, and for the garage, it is quite suitable to lay on bituminous paper.

Additional advice and recommendations

Here we are and discussed the ways of laying the waterproof, you are now familiar with all the necessary information in order to block the roof of the garage, house or other construction object.

To store the waterproofing, you just have to follow certain rules. The first and most important thing is to keep the ego away from fire and heat, just as it should be in an upright position.

During installation, it is necessary to comply with safety techniques, namely: wear clothes that will cover your entire body, as well as gloves.

This is necessary to prevent the product from reaching the skin surface.

If you are going to use the waterproofing as a roof finish, pay attention to the roll-up view of the material, its main purpose is just this type of work, because the laying of other materials on top of it is not provided.

This type of waterproofing is designated by the TPP label packaging.
