What wind and snow rating does a retractable pergola have?

Retractable fabric canopy pergolas carry significantly higher wind ratings than a standard folding arm awning thanks to their fixed front support posts and aluminium framework, making them well suited to the UK climate and more exposed sites. To be clear we refer here to an electric operated retractable system with high tension systems used for the fabric cover and enclosure on all sides The fabric canopy is engaged in most models at either side using a ‘zip’ guide and then the front profile pulls the fabric out under tension too, providing a tight fabric cover when extended. Enhanced pergola models with aluminium cross bars will have actual rainfall tests and snow load testing figures and use a triple layer fabric cover too. They also have their own rainwater drainage systems built in In very high winds and storms we do advise retracting the fabric roof.. Exact ratings depend on the model, size and how it’s installed however.
