Your Aluminium Roofing Questions, Answered
A few of the things installers and fabricators ask us most before deciding which Sheerline Bespoke system to specify.
The S1 is our roof lantern, built for maximum light and a sleek, low profile finish. The S2 is a slimline conservatory roof designed for wider spans, and the S3 is our newer single pitch system, built for fast installation on lean-to style extensions.
Yes. Our roof systems, rooflights and arched frames are all designed to work together, so you can mix and match to suit the project while keeping consistent colours and finishes throughout.
SheerVent works with the S1, S2 and S3 systems, giving you a flush, automated ventilation option across our full glazed roof range.
Yes. Our aluminium systems are used across both residential extensions and larger commercial glazing projects, with technical support available either way.
It depends on the pitch, span and finish you need. Our team can talk you through the options and recommend the right system once we know a bit more about the project.
We supply installers, fabricators and builders, not homeowners directly. If you're a homeowner, we can point you toward one of our trade partners.

Built to withstand British weather
Our roofing systems are engineered to tackle the toughest conditions. Whether you’re installing a new roof or upgrading an existing one, we use quality materials that resist moisture, eliminate leaks, and ensure long-term durability.
Our unique Thermlock® multi-chamber technology in the eaves beams, ridges, and rafters delivers outstanding thermal insulation, while our S1, S2 and S3 roofs are available with SheerVent®, a flush-fit, thermally broken vent that blends seamlessly into both for intelligent roof ventilation.
