How to make a waterproofing of the roof of the garage with

Warm, spacious garage - the dream of every responsible motorist who cares about the condition of his faithful "iron horse". However, the construction and equipment of the place of storage of the machine are most often done with their own hands in order to save money or materials. Most of the difficulties arise from the masters in the construction of the roof, because leakage can cause significant damage to the property contained in the garage. So that the atmospheric moisture does not penetrate inside the premises, a quality and thorough waterproofing of the roof of the garage is necessary.

Design features

Garage - usually single or attached to the main house structure, used for the maintenance of vehicles, seasonal storage of things. Most often, its roof is a simple one-sided, flat or two-sided construction. As a finishing waterproofing coating most often used affordable roll materials, corrugated roofing, roofing membranes. The garage roof structure has the following features:

• Minimum bias. As a rule, the garage roof has a small slope. Most often used flat designs, which are used to create bitumen mastic or roll materials. This parameter significantly limits the choice of roofing.
• Small square. The roof of the garage is usually small in size, so it’s more rational to use rolled and liquid waterproofing materials that overlap each other to cover.
• High snow load and susceptibility to leakage. Due to the small slope of the garage roof is subject to an increased risk of leakage, therefore, it requires additional waterproofing.

Note! To the roof of the garage served longer, it must be multi-layered. Such popular roofing materials as roofing felt and roofing material are laid in 4-5 layers with overlap between them to achieve a hermetic coating. For the treatment of seams, bitumen-based mastic is used, which coats the joints between the layers and primes the roof base.

Types of garage waterproofing

Many motorists are wondering how to make a waterproofing of the roof of the garage with their own hands, and what materials for this is better to use. The construction market has a wide range of waterproofing coatings, which differ in service life, reliability and installation method. The following types are most commonly used:

1. Waterproofing film. A thin waterproofing film of polyethylene serves as an excellent barrier to the penetration of atmospheric moisture. It is used as a lining waterproofing for the roof of the garage, as it does not have sufficient strength to finish.
2. Rolled bitumen materials. Coatings based on roofing paperboard impregnated with oil bitumen are optimally suited for waterproofing a garage roof. They do not pass water, have satisfactory strength properties and serve for a long time. Roofing materials and roofing materials belonging to this category of roofing are used as lining and finishing waterproofing, depending on the number of layers of material in the roofing pie.
3. Roll membrane materials. Rather expensive types of waterproofing coatings, which are characterized by increased resistance to moisture, strength and elasticity. The only disadvantage of this option is considered expensive.
4. Liquid waterproofing. Bitumen mastic is a liquid waterproofing material that is supplied either in the form of a finished mixture or in the form of a solid piece of bitumen, it must be melted for use. Mastic is used for priming the base of the roof, gluing roofing material and waterproofing joints.

Important! Waterproofing for the roof can be lining and finishing, depending on the strength and resistance of the material. Some coatings (roofing membranes, rolled bituminous materials) can be used as an independent coating, while others, for example, film or mastic are used only as auxiliary.

Waterproofing technology

Waterproofing the roof of the garage with your own hands is a routine operation, familiar to every master, and is carried out regularly to protect the structure from leaks. Впервые она производится во время возведения кровли, а затем периодически повторяется по мере появления мелких дефектов и износа. Technology of installation of waterproofing material состоит из следующих этапов:

• First, the truss frame of the garage roof is constructed, the truss legs are installed so that their edges are in the same plane.
• Waterproofing material is cut into strips corresponding to the length of the slope.
• The cut strips are laid on the surface of the roof slope so that they go over each other by 15-20 cm.
• The waterproofing is fixed on the rafter legs so that it sags a little, so that the pressure arising from water does not cause the material to rupture.
• On top of the waterproofing film along the rafters, the laths of the contra-grille are fixed, forming a ventilation gap.

Note that there are different ways of fixing the waterproofing material. The mechanical method is to attach the strips with a construction stapler or nails. Glue implies gluing waterproofing to the rafters, for which bitumen mastic is used.
