Our lean-to glass roofs are able to accommodate many different types of glass including solar-control, self-cleaning and tinted.

Our glass lean-to roofs remove the need for additional structural support with an integral I-beam steel hidden within the roof structure that sits on top of your wall or on supports on either side. The advanced design enables clear spans of up to 6m to be accommodated, whilst also allowing for a built-in horizontal aluminium colour matched gutter.

Roof Design

Roof design

Our lean to glass roofs can be manufactured with rafters up to 1000mm apart in a range of pitches from 5° up to 45°, utilising a bespoke wall bracket.

The roof system can be designed to incorporate opening roof lights, for ventilation, which sit neatly into the roof design and can be manually, electrically or automatically operated.

For the ultimate in finishing touches LED down-lights can be incorporated within the rafters of the roof, a neat way of adding additional internal lighting.
