How is the roof rainwater system checked?

Satunnainen

Checking the roof rainwater system is an important part of building maintenance, as a functioning rainwater system prevents water from entering the structures and reduces the risk of moisture damage. In this article, we go through how to check the roof rainwater system step by step.

1. Preparations

Before starting the inspection, it is important to make sure you have the necessary tools and safety equipment. For example, you need a ladder, gloves, safety glasses and possibly also a pressure washer. Also, make sure that the weather conditions are favorable, as working on the roof in rain or strong wind can be dangerous.

2. Inspection of rib wells and downpipes

The first step is to check the gutters and downspouts. These parts must be clean and free of debris so that the water can flow freely. You can use a brush or pressure washer to remove debris.

  • Check that there are no leaves, branches or other debris in the gutters.
  • Make sure the downpipes are not blocked. You can test this by pouring water into the drain well and watching that the water flows down unimpeded.

3. Gutter check

Next, check the gutters. Gutters must be intact and properly attached to be able to direct water away from the roof.

  1. Check that there are no cracks or holes in the gutters.
  2. Make sure the gutters are fixed firmly and at the right angle so that the water flows away from them.
  3. Remove all debris and dirt from the gutters.

4. Inspection of joints and seals

Connections and seals are critical parts of the rainwater system, as they prevent water from entering the structures.

  • Check that all connections are tight and intact.
  • Replace worn or damaged seals with new ones.

5. Inspection of roof drains

Ceiling drains are especially important on flat roofs, as they direct water away from the roof. Make sure the roof drains are clean and functional.

  1. Remove debris and dirt from roof drains.
  2. Check that the protective grates of the roof wells are intact and in place.

6. Rainwater system testing

Finally, test the entire rainwater system by pouring water on the roof and observing that the water flows unhindered through the entire system. This will help ensure that all parts are working properly and that any potential problems will come to light.

Summary

Checking the roof rainwater system is an important part of building maintenance. Regular inspection and maintenance help prevent moisture damage and extend the life of the system. Remember to check gutters, downspouts, gutters, joints, seals and roof drains regularly, and always test the system after checking.
