How does rainwater drainage work on louvre roofs?

A louvre roof not only offers protection from sun and wind, but is also a intelligent solution for rainwater drainage. The my-pergola24.com system is characterized by a particularly well thought-out design that ensures fully integrated water drainage. In this article, we explain how the rainwater drainage system works, what technical advantages it offers and why it is particularly durable and low-maintenance.

The basic principles of rainwater drainage

A louvre roof is equipped with minimally inclined louvres that efficiently drain the water when closed. As a rule, they slope 0,3% from the motor, but the frame of the construction and the rain panels are level. The system from my-pergola24.com goes one step further:

  1. Integrated gutters: The water is drained through the slats into discreetly integrated gutters on the sides. The slatted roof from my-pergola24.com offers better splash prevention than other systems, even in heavy rain.
  2. discharge into the posts: The integrated gutters lead the water downwards through the posts and only with the louvre roof from my-pergola24.com is it possible to install the electrics and switches in the water stand if desired. This is necessary if, for example, stands are not required in the project or are omitted for aesthetic reasons.
  3. Discrete drainage: The water is drained into a channel system or into the ground at the base of the posts. We implement the outlet position and cross-section according to specifications.

This closed system in the louvre roof ensures that no water drips off uncontrollably and the terrace stays dry.

Technical advantages of the my-pergola24.com system

  1. Effective water drainage

  • Inclined slats: The inclination of the slats allows the water to be directed into the integrated gutters in a controlled manner. (The inclination is not visually noticeable.)
  • High capacity: Even in heavy rain, the system remains powerful and prevents water accumulation, and the integrated gutter on the shaped pipe (new from 2025 - no assembly required) better prevents splash water.
  1. low maintenance

  • Corrosion-free materials: The gutters and posts are made of high-quality powder-coated aluminum, which is particularly durable. The corners should be sealed with Sika Flex to ensure long-term tightness.
  • Self-cleaning effect: The water flow automatically flushes small dirt particles out of the system. Please remove heavy dirt or leaves.
  1. Inconspicuous design

  • The water drainage is invisibly integrated so that the elegant design of the louvre roof is retained.

Many competing products either do not offer integrated rainwater drainage or rely on visible channels that affect the design. In addition, inferior materials can lead to blockages or corrosion.

Why is rainwater drainage important?

  1. Protecting the terrace: Controlled water drainage prevents rainwater from dripping onto the terrace and damaging it. And it protects your furniture.
  2. Longevity of the system: By draining the water, stagnant water is prevented from putting strain on the structure.
  3. Comfort: Even when it rains, the terrace remains usable without water running off uncontrollably.
