Types of roof waterproofing. What types of roof waterproofing are there?
Roof waterproofing is undoubtedly an important stage in the construction of any building. It helps protect the roof and the entire building from the adverse effects of the environment - precipitation, strong wind, as well as accumulated moisture, condensation, rot, mold and impacts. Without waterproofing work, it is quite likely that the service life of the roof will be significantly shorter. Choosing a poor-quality waterproofing material or carrying out the work incorrectly can cause roof leaks, rotting of the roof structure or the spread of mold and fungi. That is why this topic is very relevant. After reading this article, you will learn what types of roof waterproofing there are and which type is best suited for your home.
Requirements for waterproofing materials
At the moment, many different materials are used for roof waterproofing. Such variety is caused by the need to choose a material that will be ideally suited for a house in a particular area. The climate of the region, minimum and maximum temperatures, temperature fluctuations and the amount of precipitation are taken into account.
A number of requirements are imposed on waterproofing materials. Such a material must be moisture-proof, strong, elastic and heat-resistant. The last requirement is not mandatory, but you will agree that it is much more pleasant when your home is protected not only from moisture, but also from cold.
What types of roof waterproofing are there?
There are several types of roof waterproofing:
- Waterproofing with roll materials.
- Waterproofing with special paints and mastics.
- Waterproofing using sheet materials.
- Waterproofing with polymer membranes.
Each of the listed types involves the use of a specific material to create waterproofing. When the first type is used, special roll materials and binders are applied; with the second type, special liquid and viscous substances are used. The materials used in the third and fourth types are more complex and expensive. These include various sheet materials (for example, metal sheets) and synthetic films. Let us consider the features of these types of roof waterproofing.
Features of roof waterproofing types
Waterproofing with roll materials and special paints is a simple and inexpensive way to protect your roof and the entire house. Roll materials are elastic and therefore are excellent waterproofing materials for covering roofs of any shape. Take roofing felt, for example (a popular roll insulation material): it is not only elastic, but also lightweight. Covering a roof with such a material is durable and inexpensive.
Roofs are also coated with various paints and mastics (liquid roof waterproofing). This type is simple and inexpensive. Bitumen and polyurethane mastics, as well as rubber paint, are used. The liquid material is applied to the roof in several layers, with a thickness of no more than 3 mm. The result is an even seamless coating.
Waterproofing with sheet materials is a more complex and expensive type, but it is also more reliable. Sheets of metal or plastic are used. They are fixed to the roof, and all seams and joints are welded. Such waterproofing will last much longer, and the likelihood of leaks or cracks is much lower. The last type of roof waterproofing to be discussed is waterproofing with special films. Such films are not cheap, but their installation is quite simple. It is very important to choose films with high resistance to ultraviolet rays. These are the films intended for exterior covering, not interior use. To make this type of waterproofing last a long time, you should choose films with additional additives. Such additives make waterproofing films stronger and more resistant to mechanical impact.
It is worth taking a responsible approach to choosing the type of roof waterproofing. Do not assume that the more expensive option is always better. If your future roof will have a non-standard shape, the best solution is a roll covering; if it is flat and simple, then the other types may also be suitable.
