The roof is a part of the building that is exposed to harmful factors every day, – precipitation, wind or solar radiation. It is important that the structure and roofing are properly executed, which will ensure trouble-free use of the building for many years. One of the key issues turns out to be the waterproofing of the roof, that is, its protection from moisture.
Why shouldn’t you forget about proper roof waterproofing?
The advantages of durable and airtight roofing are known to all of us. If leaks appear on the roof structure, or worse, in the rooms, it means that water is getting in through the sheathing. All it takes is a small leak or even careless roofing workmanship for leaks to become the bane of homeowners causing mold or fungus to grow on the walls. When wood rot occurs, then it is necessary not only to replace the roofing itself, but also the rafter framing – this involves really high costs. Flat roofs in particular are exposed to the damaging effects of water, which, due to their construction, cannot effectively drain precipitation. It is important to remember to waterproof them, placing this work in the hands of professionals.
What are the methods of waterproofing the roof?
Choosing the right method of waterproofing a roof depends on its construction and what kind of sheathing it was covered with. Until a few years ago, the most popular method of waterproofing was tar paper, but today specialists are moving away from this material. Tar paper is relatively simple to lay, and if it is laid correctly on the roof it is seemingly airtight. However, the problem arises after a few years, when the felt begins to crack and delaminate due to the natural aging of this material. Even by choosing a top-of-the-line roofing felt, you can only delay this process, which leads to localized leaking and moisture accumulation.
An effective and quick-to-apply method of waterproofing a roof is a liquid membrane, which is made from polyurethane resin. It is a material that forms a homogeneous layer bonded to the substrate, which is resistant to long-term moisture, even if it is standing water. The same material can be used, for example, to seal basements, terraces or pool walls. The liquid membrane does not corrode, is resistant to sunlight and changing temperatures, so it can be successfully used for outdoor work. The material is particularly recommended for waterproofing flat roofs and areas prone to leakage, such as around chimneys or ventilation equipment. Another advantage of the liquid membrane is the simple application and safety of use regardless of the type of roofing.
Can waterproofing be done when the roof is leaking?
Most often, roof leaks are noticed only when the problem becomes serious. However, this does not mean that there is no way out of the situation – effective waterproofing is possible, but the condition of the roof must be assessed by professionals. Liquid membrane can be successfully used to waterproof roofs even in old buildings. Its application results in a protective layer that effectively reaches the nooks and crannies of both flat and sloped roofs. The liquid membrane can be used together with roofing paper, tiles or tile.
Why should you outsource your roof waterproofing to a professional company?
Performing the correct waterproofing of the roof has a decisive impact on the tightness of the entire roofing. Even if we think that the work has been done well, leaks may only reveal themselves after some time. For this reason, it is advisable to outsource the work to a professional company, RS-MAL, which has years of experience and trained employees. Having the work done by professionals guarantees that the waterproofing of the roof will be tight and will be done according to the recommendations of the manufacturer of the liquid membrane. As a result, the roof will not leak, and you can easily and quickly get rid of even small leaks. It will be difficult for a layman to locate the leak and apply the waterproofing in a professional manner – the risk of error is then high. Often it turns out that in this way only apparent savings can be achieved. In the end, you have to use the corrections of specialists anyway. RS-MAL provides a guarantee for its work, so customers can be sure that the waterproofing made will last for many years without causing any problems.
