How is the waterproofing of the roofs ensured?
The waterproofness of a roof is an essential part of a building’s durability and living comfort. A waterproof roof protects the building from moisture, mold and other damage caused by leaks. Waterproofing is ensured through a combination of the right roofing material, careful installation, drainage and regular maintenance.
1. Choice of roofing material
The choice of roofing material has a significant impact on the waterproofing of the roof. The most common roofing materials are:
- Bitumen felt (bitumikate): A durable, waterproof material that is especially suitable for sloping roofs.
- Tile roof: A traditional and durable option, but it requires regular maintenance and inspection.
- Sheet metal roof: Light and easy to install, but it can rust if not properly maintained.
- Rubber bitumen coating: A flexible and durable material that is especially suitable for flat roofs.
2. Waterproof coatings and membranes
Waterproof coatings and membranes are an effective way to improve the waterproofness of a roof. They are used especially at seams, joints and other critical points where the risk of leakage is greatest. Bitumen membranes and elastomeric coatings, for example, offer good protection against water.
3. Drainage
Roof drains and rainwater systems that direct water away from the roof are an important part of waterproofing. Working gutters and downspouts prevent water from accumulating on the roof, which reduces the risk of leaks.
4. Regular inspection and maintenance
The roof should be inspected at least twice a year, in spring and autumn, and always after strong storms. During the inspection, pay attention to:
- Condition of the roofing material: check for cracks, tears or other damage.
- Roof tiles or panels: make sure they are in place and intact.
- Seams and joints: check that they are tight and intact.
- Gutters and downspouts: clean them of debris and leaves so water can flow freely.
5. Using a professional
Many maintenance tasks can be done yourself, but it is a good idea to have a professional inspect the roof regularly. A professional can identify hidden problems and fix them before they cause bigger damage, and give recommendations for further maintenance.
