If you are one of those who suffer when entering the winter from a leak in the ceilings, damp in the walls, or even drops of water seeping into your home, it is best for you to make a waterproofing of your roof so that you do not suffer in the future from the effects of leakage. Waterproofing is not limited to roof insulation only, it can also isolate water tanks or swimming pools. In this article, we will discuss all your waterproofing questions and the types and methods of waterproofing.
As we talked about the best methods and types of thermal insulation before and its importance, we will talk today about the methods and types of waterproofing roofs and their benefits.
For a long time, residents of the last floors often thought about choosing the best waterproofing for roofs to protect them from moisture and water damage.

There are two methods used to isolate surfaces from water previously
It is one of the most common methods used. This type of insulation is done by making small waterways or leaky pipes. Often times this water is used for positive things like irrigating your home garden or watering young seedlings.
This method is environmentally friendly, but it is a primitive method that is not suitable when there are damages and damages to buildings as a result of water leakage and dampness, so at that time resorting to the most effective insulation methods.
Passive water insulation:
It is by painting the other side of the place of water leakage with insulating materials, but it is a method of little use and is used only when there are reasons that prevent the implementation of the method of positive insulation.
1- Tar or mazout, or what is known as (pitch):
Its use is relatively old and simple, and it is a derivative of petroleum and is poured on the roofs, so the water is very large insulation and the building is protected.
2- Metal Sheets:
There are many types of it, such as lead plates, iron, aluminum, stainless steel and other types of metals. This waterproofing method is characterized by its low cost, but it has a major disadvantage, which is rust, as these metals rust and corrode when exposed to water for long periods.

Of course, each problem has a solution, and the solution to that problem is to paint the panels with a rust-resistant material that isolates the surface of the panels from water, air and moisture.
3- Insulation using asphalt material:
This material is formed and is used in the form of three asphalt plates and asphalt rolls or unmodified solid asphalt. Asphalt has advantages and disadvantages, including that it is the cheapest insulation material and has a great ability to waterproof and thermal insulation, but one of its disadvantages is that it does not last much and cracks so that water seeps through. To find out how asphalt is made, all the information in this article, how is asphalt made, and what are its different uses
4- Wooden panels:
And it is also used in cold countries and placed diagonally, but the wood is not fireproof, which is a major disadvantage to its use.
As for the chemicals, they are:
1- Insulation with foam or (polyurethane):
It is sprayed on the surfaces and one of its advantages is that it isolates the smallest hard-to-reach places compared to other types of waterproofing. In this type, water insulation is 100% and it is recommended to paint an acrylic layer over it to protect more from UV rays.
And this type of waterproofing and thermal insulation lasts for nearly twenty years.
2- Insulation with liquid bitumen:
It is a synthetic chemical and one of its great advantages is that it deals with all types of surfaces, whether flat, zigzag or defects. This material is poured, and all the voids to be isolated are filled. Its advantages are also resistance to insects and fungi.

3- Polyethylene insulation:
It is an easy-to-use type that comes in the form of black linoleum and is no more than 46 cm thick. Polyethylene insulation is characterized by being light and not heavy on the roofs. It is flexible and suitable for old buildings with roofs that do not bear large loads and have curves, problems or uneven.
4- Brick insulation:
It is a material made of burnt clay or terracotta, which I have seen mostly in European-themed homes that have red roofs. This material is placed on the roofs diagonally to let water or snow slip off them in cold weather countries.
What distinguishes this type of waterproofing is that it is not affected by moisture and water, and its color can be changed by means of paints to give an aesthetic appearance.

You can choose any type of surface thermal insulation that suits the shape and design of your home and also in proportion to the budget set for this matter. And if you want to avoid the problems of heat and water leakage together and get the greatest possible comfort
