Roof flashing and capping installation work on a building in Caldas da Rainha.
Roof flashing and capping installation is a fundamental task in building construction and rehabilitation, especially in areas like Caldas da Rainha, where exposure to rain and humidity is frequent.
What are roof flashings?
Roof flashings are metallic elements, usually made of zinc, aluminum, or galvanized sheet metal, applied to critical areas of roofs to prevent water ingress. They are used, for example, at the junctions between roofs and walls, around chimneys, or in skylight finishes.
Their main function is to ensure the watertightness of these points, channeling rainwater away from the structure and preventing leaks.
What is capping?
Capping consists of placing a protective layer on top of walls, parapets, or external walls. It can be done with different materials, such as stone, concrete, or metal pieces.
Its purpose is to prevent water from penetrating the top of vertical elements, increase the durability of the construction, and provide a more careful finish.
Importance
Proper installation of flashing and capping is essential to protect the building against moisture, prevent structural damage, and extend the lifespan of materials. In regions with higher rainfall, such as Caldas da Rainha, these elements assume an even more important role in the conservation of properties.
