  • Survey before any quote

    Nobody prices a roof from the pavement. The inspection happens first and the figure follows the evidence.

  • Written specification and price

    The system, the build-up and the cost sit on paper before anyone lifts a tool.

  • Safe2Torch fire discipline

    Combustible details are designed out of the torching zone and finished cold instead.

  • Photographed handover records

    You keep dated photographs of what was actually done, not a verbal assurance about it.

What we do for commercial roofs

Roof surveys & condition reports

The starting point for any roof you are responsible for: a written, photographed record of defects, priorities and budget guidance.

Flat roof surveys and condition reports

Repairs

Leak diagnosis and lasting repairs on felt, asphalt and other flat roof coverings, on occupied buildings and portfolios.

Flat roof and leak repairs

Refurbishment

When a roof is near the end of its life: an honest options guide across repair, overlay and strip and renew, decided by the survey.

Flat roof refurbishment options

Built for occupied buildings

Commercial roofing is rarely about the roof alone. There are residents below, businesses trading, plant on the roof and people who need to know what is happening and when. We run tidy, safe sites, agree access and timings with building managers up front, and report in writing with photographs, so you always have something concrete to pass on.

Safe2Torch discipline as standard

Before any torch work, the roof is assessed for combustible details: timber cladding, eaves boxes, junctions with lightweight walls. In line with the industry Safe2Torch guidance, those zones are designed out of the torching area and finished with cold-applied liquid waterproofing instead. No open flame near combustible details, on any roof, ever.

Our map is South London first, plus one deliberate western outpost in W3 (Acton), covered on scheduled runs with the same discipline.

Who we work with

Occupied buildings share the same fundamentals, but each sector has its own constraints. How we handle them, sector by sector:

Why start with a survey?

Because everything else depends on it. A condition survey tells you whether a leak needs a repair or the roof needs a plan, what a sensible maintenance programme looks like, and when refurbishment becomes the economical choice. It turns a roof from an unknown liability into a line you can budget for. Surveys and planned maintenance are priced per roof and portfolio, agreed in writing before we start.

Frequently asked questions

Do you work on occupied buildings?

Yes. Most commercial flat roofing happens over occupied space, so we plan for it: tidy sites, clear communication with building managers and residents, and cold-applied liquid waterproofing near combustible details so no open flame goes where it does not belong.

Which clients do you work with?

Property managers, managing agents, housing associations and facilities managers across South London and Greater London. We also work directly with homeowners on smaller flat roofs.

How do you keep torch work safe on commercial roofs?

By following the industry Safe2Torch guidance: the roof is assessed for combustible details before work starts, torch-applied membrane is kept away from them, and those zones are finished with cold-applied liquid waterproofing that needs no flame at all.

What is the first step for a commercial roof?

A roof condition survey. It records where the roof is in its life, what needs attention now and what can wait, and gives you a written, photographed report you can plan and budget against.

Do you offer maintenance contracts?

Yes, as planned preventative maintenance (PPM) programmes: scheduled inspections, drainage clearance, minor repairs and photographic condition reports. Programmes are priced per roof and portfolio after an initial survey.

Responsible for a flat roof portfolio?

Tell us what you manage and where. We will suggest a sensible first step, usually a condition survey of the roofs you know least about.
