Roofing for Facilities Managers & Trading Premises
Offices, retail and industrial units cannot stop trading because a roof needs attention. Our job is to work around yours: access and permits agreed in advance, disruption timed and flagged, and every visit documented so the building file stays complete.

Disruption is a planning failure
Almost everything a flat roof needs can be done without interrupting the business below, provided it is sequenced properly. Surveys and planned maintenance visits fit around opening hours; noisy or access-affecting work is flagged and timed in advance; deliveries and waste move on agreed routes. Where a site runs a permit-to-work system for roof access or hot works, we work inside it, with method statements submitted ahead and every hot-works permit closed before we leave the roof.
Weak points
Plant, penetrations and the real causes of leaks
Retail and office concentrations set their own rhythm. Working over one of outer London's largest shopping centres, or across the offices and riverside stock at Twickenham and Teddington, means fitting around opening hours before anything else is decided.
Commercial roofs carry the most hardware: air handling units, supports, cable trays, gas lines, satellite mounts. Every one is a penetration or an upstand, and that is where leaks start. Our surveys pay specific attention to detailing around plant, and where sheet membrane cannot form a clean junction we use cold-applied liquid waterproofing, which handles that geometry without a joint in it. Where the roof under all that hardware is a sheeted metal deck, the fixings and the laps are inspected as carefully as the plant they carry.
On a portfolio the cheapest opening move is a condition survey of whichever roofs carry the thinnest paperwork; capital work then splits between refurbishment and a full rebuild. How we run occupied sites is covered once, on the commercial hub.
The elements that generate the tickets
Ask any FM team which roof defects reach them most and it is rarely the open field. It is box gutters and internal outlets, which overflow inward over an upstand instead of spilling down an outside wall where it would do no harm. It is rooflights and the kerbs they sit on, which are also the reason a roof with any age on it is treated as fragile until proven otherwise. On offices and mixed-use buildings it is terraces and podium decks, where the failure hides under a surface tenants use, and balconies, which deliver their water straight into the space below.
The covering itself sets the rest of the agenda. Retail and office stock refurbished since the nineties is commonly single ply, TPO or EPDM, now failing at welds rather than in the sheet, while older buildings still carry mastic asphalt that stiffens with age. After bad weather, what a landlord, an insurer or a head office actually needs is a dated report of what failed, produced alongside the repair rather than reconstructed from memory a fortnight later.
Liability
The lease usually decides who is buying
Before anything technical there is a question of liability. On a full repairing lease the roof is the occupier's problem; elsewhere it sits with the landlord and comes back through the service charge; on a multi-let building it may be apportioned. Whoever is instructing us, the answer determines what the document has to prove, and it is worth establishing before the survey rather than after the invoice.
Dilapidations sharpen this at both ends of a term. A covering allowed to deteriorate quietly across a lease becomes a schedule item at the end of it, and the argument then is about what condition it was in when the tenant took it on. A dated record made early is worth considerably more in that conversation than an opinion formed late.
Procurement
Nothing happens without a job number
Facilities work arrives through a system, not through a phone call: a helpdesk, a ticket, a purchase order, a supplier record, sometimes a portal that wants documents uploaded in a particular order. We are comfortable inside that, and the practical requirement is simply that the paperwork we return matches the reference the work was raised under, so that a completed job closes cleanly rather than sitting open while somebody works out which building it belonged to.
The approval chain behind the ticket is usually short but strict: someone with a spend limit signs below a threshold, and above it the request goes to a client-side property manager or a regional lead who has never seen the building. That second reader is who the summary paragraph is written for.
Timing
The window is narrower than the work
Trading hours, delivery slots, shift patterns and public access all shrink the time a roof is genuinely available, and the constraint is rarely the roofing itself. Where noise or access is unavoidable, the realistic options are early starts, weekends or an evening shift, and which of those suits is a question for the building rather than for us. Roof access on a let building often needs the occupier's agreement as well as the manager's, which is another reason to settle access before a date is fixed rather than on the morning. Where the building cannot pause at all, the sequencing that answers it has a page of its own.
Money
Reactive-only is the expensive way to run a roof
On a trading building the roof repair is seldom the largest number. An attendance forced by a failure costs more than the same job booked in advance; the water lands on stock, ceilings, flooring or IT rather than on an empty deck; and the disruption to trade is not recoverable. The pattern to watch for is the same roof generating tickets in different places over a couple of years, which is a spent covering being bought back a ticket at a time.
At scale
What a programme across a managed portfolio looks like
Visits scheduled to the building's own calendar rather than to a national one, with the roofs that carry plant or internal drainage seen before the wet months, gutters and outlets cleared as a standing item, small failures closed on the visit rather than raised as a second job, and a return per building written against the reference it was raised under. Over a couple of cycles that turns an unpredictable reactive line into a planned one, which is usually the number an FM is being asked to defend.
Before we quote
The information that makes a quotation firm
Building addresses, approximate floor areas and what each one is used for. Then: who holds the roof under the lease, how access works and whether a permit system applies, the hours in which work is realistically possible, whether plant on the roof belongs to you or to a tenant, and the reference the work should be raised against. If there is a CAFM record of previous roof tickets, it is often more revealing than any description of the building.
Questions
Frequently asked questions
Can roofing work happen while the building trades?
Usually, with planning. Surveys, maintenance visits and most repairs can be sequenced around opening hours, deliveries and quiet periods. Where work is noisy or affects access, it is flagged and timed in advance, so operations decide the programme rather than discovering it.
Do you work within permit-to-work systems?
Yes. Where a site runs permits for roof access, hot works or working at height, we work inside the system: method statements and risk assessments submitted in advance, permits signed before work starts, and every hot-works permit closed before we leave.
What about all the plant on our roof?
Plant is where flat roofs leak: units, supports, cable trays and pipe penetrations interrupt the membrane and collect debris. We survey and detail around plant specifically, using cold-applied liquid waterproofing for awkward penetrations and upstands where sheet membrane cannot form a clean seal without joints.
Can you schedule works across several sites?
Yes. Portfolios are handled roof by roof with one combined picture: each site surveyed and documented, priorities compared across the estate, and maintenance or repairs scheduled to suit operations at each building. Nothing is costed until an opening survey has established the scale of each roof.
Where does an FM portfolio start?
A survey on whichever buildings you have least current information about, delivered as a photographed, prioritised report per building. It gives you evidence for budgets and a defensible answer to the question every FM gets eventually: did we know about that roof?
A roof problem that cannot stop the business?
That is the constraint we plan around every day. Tell us about the site and the hours it keeps.
We need a little more before we can send that: a name, the postcode of the roof, what is happening with it, and either a phone number or an email address.
Sorry, that did not send. What you wrote is still here, so press send again when you have a signal. If it will not go, ring 07593 196505 or email office@pluvian.uk.
That has come through a few times already. If the first one did not arrive, ring us instead or email office@pluvian.uk and we will pick it up from there.
Coming out and pricing the work is free; a written condition survey carries a fee, agreed before the visit and taken off the price of the work if you go ahead.
