Commercial roofing in London
Ronald G Graham delivers commercial, industrial and healthcare roofing across London — flat-roof renewals, single-ply and cold-applied liquid systems, cladding and planned maintenance — backed by a London office and NFRC award-winning craftsmanship.
Commercial & industrial roofing for London buildings
Ronald G Graham is an Edinburgh-headquartered, family-run roofing contractor that takes on commercial and industrial contracts across the UK. In London we work from our London office, bringing accredited, award-winning craftsmanship to commercial, industrial, healthcare, education and heritage buildings.
A recent example is The Whittington Hospital in Archway, where we waterproofed 1,400 m² of roof over occupied NHS wards using a cold-applied, low-odour liquid system with no hot works — so clinical areas stayed in use throughout. It's the kind of sensitive, occupied-site work we're built for.
Systems specified for the building
A commercial flat roof is only as good as the system specified for it. We install single-ply membranes (Bauder, IKO) on large commercial and industrial roofs, EPDM rubber where a single-piece cover suits a simpler roof, and liquid-applied systems for complex, heavily detailed roofs or for over-coating without a full strip. We also deliver full re-roofs, cladding, gutter-lining and licensed asbestos cement removal — the whole envelope, treated as one.
Built for commercial and public-sector work
We're an NFRC UK Roofing Award winner, TrustMark registered, a SELECT member and ISOQAR / UKAS accredited. For commercial, NHS and education clients that means method statements, risk assessments and full handover documentation as standard, and a programme planned around your operations. We also offer planned maintenance contracts to landlords, managing agents and businesses.

Do you cover London?
Yes. Ronald G Graham takes on commercial and industrial roofing contracts in London, supported by our London office. We're an Edinburgh-headquartered, NFRC UK Roofing Award-winning family firm — recent London work includes waterproofing 1,400 m² of roof at The Whittington Hospital in Archway.
What kind of London projects do you take on?
Commercial, industrial, healthcare, education and heritage roofs: flat-roof renewals and re-roofs in single-ply (Bauder, IKO), EPDM and liquid-applied systems; cladding; gutter-lining; licensed asbestos removal; and planned maintenance. We're set up for occupied, sensitive sites where disruption isn't an option.
Can you work on occupied or sensitive buildings like hospitals?
Yes — it's a core strength. At The Whittington Hospital we waterproofed live wards using a cold-applied, low-odour liquid system with no hot works, so clinical areas stayed in use throughout. We phase the programme, segregate the working area and keep the building watertight at every stage.
Are you accredited for commercial and public-sector work?
Yes — NFRC member and UK Roofing Award winner, TrustMark registered, SELECT member and ISOQAR / UKAS accredited. We provide method statements, risk assessments and full handover documentation, and we're experienced with NHS, education and managed-property procurement.
Do you offer planned maintenance for London commercial roofs?
Yes. We provide scheduled maintenance contracts to landlords, managing agents and businesses — annual inspections that clear gutters and outlets, check detailing and fix small problems before they become expensive failures or business interruption.
