Roof lights can transform a loft or room in roof area, providing they are properly located, sized and fitted with the correct flashings..

To make things easy we provide a single roof light (uPVC Pine Coloured top hung 550x980) that can be fitted between the rafters. This avoids cutting out any rafters, re-engineering the roof, or having to double up on any rafters.

We can supply different types of hinge points, ventilation, means of opening, sun blinds and even ‘cabriolet ‘ balcony roof lights if required.
