About JLH
Premium flat roofing for high-end property — built on craftsmanship, single-ply specialism and an obsession with getting every detail right.
Our Story
Specialists, not generalists
JLH Flat Roofing Services is a Rotherham-based flat roofing company with 18 years of hands-on experience. We specialise in one thing and do it exceptionally well: premium single-ply flat roofing.
We made a deliberate decision early on. Rather than spread ourselves thinly across every flat-roof product on the market, we chose to master the best system available — single-ply PVC — and build our reputation on getting it right, every single time. Today we're manufacturer-trained and approved across eight leading systems, and we don't fit GRP or felt.
That focus shows in the work. From a single-storey extension here in Rotherham, to a 1,000 m² green roof, a 3,000 m² commercial overlay — and even a roof we were flown out to Barbados to install — the standard never changes: premium materials, precise welded detailing and a clean, architectural finish.
We work for homeowners, builders, architects and businesses right across South Yorkshire, and we back every roof we install with a 20-year workmanship warranty. When we put our name to a roof, it's because we'd happily stand on it ourselves.

We'd rather be exceptional at one premium system than average at many. Every JLH roof is welded, tested and finished to a standard we're proud to guarantee.
