Call or email us for a quote or simply order online. We only need the finished weathered external kerb size, the type of Rooflight and the glass specification required to process an order.

Yes, for all bespoke sizes and shapes please email us at sales@overheadglazing.co.uk

Our Flat Rooflights are designed to be installed onto a kerb up-stand. This kerb should be a minimum of 150mm high to negate water ingress and should be level in one plane. The top of the kerb should be an angled plane to provide a pitch in order to help shed water from the glass and the kerb needs to be weathered.

Lead times for standard sizes are 2 to 3 weeks. Lead times for bespoke units range from  3-6 weeks, depending upon Rooflight type, glass spec and quantity required. To be 100% sure, please feel free to give us a call to discuss your project requirements

Our flat fixed rooflights are suitable for both flat and pitched roofs made of slate, tile, zinc or any other roof material, due to the independent upstand. You will need to create the upstand/kerb and then weather it with your roof material e.g. single-ply membrane, GRP, fibreglass etc. Our rooflight will then sit and seal against your weathered upstand. We provide you with all the fixings you need. You do not need any additional flashing kits with our fixed rooflights.

Yes, we do provide a self-cleaning option to all our new or existing rooflights.

Yes, our rooflight sizes include a 10mm tolerance, so you can build the kerb to the same size as the size stated on the website.
