Commercial Roofing Contractors in London
Golden Roofing Expert Ltd is a London commercial roofing contractor working on offices, schools, retail units, blocks of flats and light industrial buildings across the capital. We install, repair and maintain flat and pitched commercial roof systems, and we work around your operating hours so your building stays open while we work.
We are Checkatrade and Which? Trusted Trader approved, and members of TrustATrader (membership TT24074). That means our commercial work is vetted, insured and backed by written guarantees that vary by system and are confirmed in your quotation.
What we do for commercial clients
- Flat roof installation — single-ply membranes (EPDM, TPO, PVC), built-up felt and asphalt systems.
- Flat roof repair and overlay — leak tracing, patch repairs, and full overlays where the deck is sound.
- Pitched roof installation and re-roofing — slate, concrete tile, clay tile and metal sheeting.
- Planned preventative maintenance — scheduled inspections, gutter clearing and condition reports that stop small defects becoming claims.
- Lead work and rainwater goods — parapet flashings, outlets, hoppers and downpipes.
- Roof lights and mansafe — replacement roof lights and anchor points for safe roof access.
Commercial roof systems we install
The right system depends on the deck, the fall, the foot traffic and how long you intend to keep the building. We survey first and specify second — never the other way round.
Single-ply membranes (EPDM, TPO, PVC)
Lightweight, quick to install and available with manufacturer-backed guarantees. Well suited to large, low-pitch roofs where minimal added weight matters.
Built-up felt and asphalt
Traditional poured asphalt and built-up felt remain common across London’s older commercial stock. See our asphalt roofing services for how we install, repair and overlap these systems.
Metal roofing and standing seam
Standing seam, zinc, aluminium and steel sheeting for longer spans and architectural finishes. More detail on our metal roofing page.
Recent commercial roofing projects in London
Re-roofing a 1970s office block in Croydon
A managing agent called us about a four-storey office block in Croydon where the existing felt roof had reached the end of its life. Water was tracking through two roof lights and staining ceilings on the top floor whenever it rained heavily. Their concern was simple: the building could not close, and any work had to stay within a fixed service charge budget.
We carried out a full roof survey and found the plywood deck was still sound but the felt had blistered and split along the upstands. Rather than strip the roof, we specified a warm-roof overlay in single-ply membrane over a new insulation layer, which improved the building’s thermal performance at the same time. Two roof lights were replaced, and new outlets and a mansafe anchor point were fitted while we had the roof open.
The team worked in phases so half the roof was always watertight, and all noisy work was done before 8am. The job was completed in under three weeks with no disruption to the tenants below, and the building now carries a manufacturer-backed guarantee on the membrane.
Our commercial clients often find the same thing: the cheapest quote is rarely the cheapest roof. If you are weighing up repair versus replacement, our guide to flat roofing in London explains how we make that call.
Working with building managers and contractors
We regularly work directly for freeholders, managing agents, schools and main contractors. That means RAMS, insurance certificates, DBS-checked operatives where schools require it, and a single point of contact from survey to sign-off. If your building has asbestos in the roof, we will tell you before we start rather than after.
Where work needs to happen above a public area, we use netting, edge protection and exclusion zones in line with HSE construction guidance, and we can phase work around school terms or trading hours.

Commercial roofing FAQs
How much does a commercial roof cost in London?
Most commercial flat roofs are priced per square metre, and the figure depends on the system, access, the number of penetrations and whether the deck needs replacing. We provide a free survey and an itemised quotation so you can see exactly what you are paying for. For a rough starting point on residential work, see our guide to new roof costs in London.
Can you work outside our opening hours?
Yes. Evening, weekend and phased working is normal for us, particularly for retail and schools.
Do you offer planned maintenance?
Yes — scheduled inspections with photographic condition reports are the cheapest way to protect a commercial roof. Our roof maintenance service covers this.
What guarantee do you provide?
Guarantees vary by system and are stated in writing in your quotation, along with any manufacturer-backed element.
