Roof membranes play an important role in securing the covering. They provide protection against penetration of rainwater and snow under the roof, thanks to which the entire roof structure will not be damaged. They also ensure the removal of moisture from the inside of the building. That is why it is so important to choose the right vapor-permeable foil. These are materials that have been used in construction for years, but the variety of the offer available on the market makes it difficult to make a purchase. You can also learn what to choose and when to use it by using the services of a specialized company.
When to use roofing membranes?
Roof membranes are used as an alternative to roofing felt. However, it is distinguished by the fact that it has vapor-permeable properties. In practice, this means that it allows excess moisture to be removed from the house, and at the same time provides protection against rainwater and snow. These properties are crucial for maintaining an adequate level of moisture in the home. Man produces up to 3 liters of water per day, and improper discharge can lead to waterlogging. In practice, this can lead to the formation of fungi and molds, which have a devastating effect on health.
What to pay attention to when choosing roofing membranes?
Roof membranes have a number of parameters. Understanding what they mean will make it easier for you to choose a good product. These include the following features:
- resistance to damage (mechanical properties)
- waterproof
- functionality guaranteed
- paro permeability
Damage resistance is an important parameter, both from the point of view of assembly and from the point of view of durability. This is due to the number of layers the membrane consists of. The more there are, the higher the mechanical properties. It is also worth knowing that if you decide to use the formwork, the vapor-permeable foil may be damaged. Therefore, in this case, damage resistance will be a particularly important parameter.

Protect yourself from water
Watertightness is a parameter that determines how a membrane deals with providing protection against water or melting snow. Ensuring that the properties are correct in this regard is important for several reasons. First of all, it prevents water from entering the interior of the house. This problem is particularly acute in the case of damage to the roofing, when the membrane becomes the only layer protecting against rainfall.
guarantee of quality
Reputable manufacturers also offer a guarantee of functionality. In practice, this means that their roofing membranes retain their properties for many years. Otherwise, their manufacturer will cover the cost of the replacement.
In turn, vapor permeability determines the ability of the membrane to wick moisture to the outside. This phenomenon can be graphically described as "roof breathing". Thanks to it, the emitted water vapor does not accumulate inside the building, and thus it is not conducive to the development of fungi and mold. In extreme cases, it can also lead to the formation of condensation, which in large amounts may cause flooding of walls and ceilings.
How to choose?
Roofing membranes are popular, widely used in construction and thus have many varieties on the market. Therefore, the selection of the best product requires knowledge of the basic parameters. It is also worth using materials that have the CE mark with the EN 13859-1 standard. They indicate compliance with European standards, and thus are approved for use in the European Union.
