The concealed roof has been gaining more and more space in modern civil construction, mainly due to its aesthetic appeal and functionality. However, there are many myths and truths about this type of roofing that confuse both professionals and property owners. Furthermore, it's important to understand the details of the main parts and components, such as gutters, flashing, and parapets, which play crucial roles in the performance of this type of roof.
Myths and Truths About Concealed Roofs
1. Myth: Concealed roofs cause leaks.
Truth: When well-executed, concealed roofs do not cause leaks. The problem is usually associated with the lack of a good drainage system, such as poorly installed gutters and flashing. A well-designed project with qualified professionals ensures that water is properly drained, preventing leaks.
2. Myth: Concealed roofs don't have good ventilation.
Truth: The ventilation of a concealed roof depends on the type of construction and the materials used. Although some concealed roofs may have limited ventilation, it is possible to install adequate ventilation systems, such as exhaust fans or strategic openings, to ensure air circulation and prevent heat buildup.
3. Myth: A concealed roof is more expensive than a conventional roof.
Truth: The cost of a concealed roof can be comparable to that of a conventional roof, depending on the materials chosen and the complexity of the project. While a concealed roof may require more attention to detailing parts such as gutters and parapets, it can also save material on eaves and exterior finishing.
Detailing the Parts and Components of a Concealed Roof
To ensure proper functioning and avoid problems such as leaks, it is essential to understand the role of each component in a concealed roof. See the main ones below:
1. Gutters
Gutters are fundamental for the correct drainage of rainwater. In a concealed roof, since there are no exposed eaves, the gutters are responsible for conducting water to the drainage system without it running down the walls. 1. Roof Flashing
They can be made of materials such as aluminum, galvanized steel, or PVC, and must be installed precisely to ensure water flow, preventing accumulation or blockages.
2. Roof Flashing
Roof flashing is a protective element installed to seal the junction between the roof and walls, preventing leaks. It can be internal (when it is hidden under the tiles) or external (when it is visible). In a concealed roof, flashing is indispensable, since the parapets hide the tiles, requiring greater protection at the interfaces between walls and roofing.
3. Parapet
The parapet is an architectural element that hides the slope of the concealed roof, providing a more modern and clean look. It also serves to protect the structure against weathering and ensure an aesthetic finish. However, it is essential that the parapet has a good water drainage system, which includes gutters and flashing, to prevent water accumulation and leaks.
