Are Louvre Pergolas Waterproof?

Yes, quality louvre pergolas are designed to provide protection from rain when the louvres are fully closed. However, it's important to understand that a louvre pergola isn't the same as a fully enclosed room, and performance can vary depending on the design and installation.

When the louvres are closed, the angled aluminium blades overlap to create a roof that directs rainwater towards the integrated gutters and drainage system. This allows you to continue enjoying your outdoor area even when the weather changes.

How does a louvre pergola keep rain out?

A well-designed louvre pergola uses several features to manage rain:

• Interlocking louvres help prevent water from passing through the roof when closed.
• Integrated gutters collect water running off the louvres.
• Built-in drainage directs rainwater away through the pergola posts.
• Quality installation ensures the structure is correctly positioned and sealed.

What happens when the louvres are open?

When the louvres are open, rain will naturally enter the space underneath. This is one of the advantages of a louvre roof, you can adjust the blades depending on the weather, allowing sunlight and airflow when conditions are good and closing them when rain arrives.
