Pergolas

A pergola usually has a fabric or membrane cover; on retractable models it folds back. A bioclimatic roof uses aluminium louvres that rotate on their own axis; when they are tilted open, you keep the shade while warm air escapes upwards. A pergola is the lighter structure; a louvered roof behaves more like a rigid roof.

That depends on the cover and the slope. The cover type is chosen per project. With the right slope, water runs into the gutter and is drained from there; with too little, it can pool on the cover. Moisture on the underside in cold weather is usually condensation, not a leak.

On a retractable pergola, wind load is highest with the cover extended, so retract it before a storm. Once retracted, only the aluminium frame carries the load. Covered pergola systems are not designed to carry snow: retract the cover before snowfall and never force it when frozen. Rain and wind sensor options are assessed per project at the site survey. We look at the wind conditions at your site during the survey.

Width and projection, the model, wall-mounted or freestanding installation, the number of posts, cover and frame colour, profile bending on the curved model, and site conditions. The exact price is based on measurements taken on site.

Tell us the type of space, rough dimensions and whether the pergola will be fixed to a wall. Our team then books a visit to measure on site and check the floor, the wall and where rainwater will drain. The quote is based on these measurements.

Alterations to the exterior of an apartment building may require approval from building management or co-owners; we review this together at the site survey.

Clear leaves and dust from the gutters and drain outlets, especially in autumn. Wipe aluminium surfaces with warm water and a soft cloth. On a retractable pergola, don't leave a wet cover folded for long; letting it dry extended reduces the risk of mould.
