How is the roof rainwater system ensured?

How is the roof rainwater system ensured? The rainwater system is an important part of the functionality and durability of the building. Its purpose is to direct rainwater away from the building’s surroundings and prevent damage caused by water. The most important parts of the rainwater system are gutters, downspouts and rainwater wells.

Gutters

Gutters collect rainwater from the roof and direct it to the downspouts. Gutters can be made of different materials, such as metal or plastic. They must be of sufficient size and installed correctly so that the water flows through them unhindered.

Shockhorns

Downpipes transport rainwater to the ground or to the drain. They should be installed far enough from the building so that water does not cause moisture damage to the structures. The downpipes must also be of sufficient size so that they can lead large amounts of water away from the roof.

Rainwater wells

Rainwater wells collect rainwater from the ground and direct it away from the vicinity of the building. They prevent water from accumulating on the building’s foundations and possible floods. Rainwater wells must be regularly maintained in order for them to function effectively.
