S1 Roofing Ltd is a specialist roofing contractor delivering compliant, high‑quality roofing solutions across the UK. 


We work with main contractors, developers, housing associations, and commercial property owners, providing reliable installation, clear communication, and strong technical accuracy on every project.
In‑House Design & Bespoke Packages.


Our in‑house design team produces fully compliant, project‑specific roofing designs. We create coordinated drawings, detailing, and specification packages aligned with manufacturer guidelines, building regulations, fire performance requirements, and warranty standards. This enables us to deliver complete bespoke roofing packages, resolving drainage, interfaces, penetrations, and sequencing before work begins. Clients benefit from reduced risk, fewer variations, and a fully coordinated solution from design through to installation.


Certified Fire‑Rated Insulation Schemes
We offer certified fire‑rated insulation schemes engineered to achieve the lowest compliant build‑ups available. These systems are ideal for projects with height restrictions, refurbishment constraints, or strict fire‑performance requirements. Working with approved manufacturers, we deliver solutions that maximise fire safety while maintaining minimal build‑up thickness and full regulatory compliance.
