Landlords and managing agents hold roofs they did not build, often with little paperwork. A roof is usually noticed in two situations: when a tenant rings about a drip, or when a lease ends and the repair bill lands. A planned programme replaces both surprises with a calendar. Someone inspects the roof at set times, clears what needs clearing, records what is found and deals with faults while they are minor.
This guide describes the programme, not any single visit. For the contents of a first survey, our answer on the commercial roof survey has the detail. Here we look at what comes after: the cycle of inspections, the records that make them useful, and the budget lines that go with them. The wider service sits on our commercial roofing page.
Why a programme beats reacting to leaks
Reactive repair is an expensive habit. A leak reported in January has already damaged stock, ceiling tiles or insulation, access has to be arranged at short notice and in poor weather, and the repair is made under pressure with little time to investigate the cause. A programme moves the work to a dry week of your choosing.
Small faults are cheap, wet ones are not
A blocked outlet, a split sealant bead and a lifted lap are modest jobs in themselves. Left alone, each lets water into the build-up, where it wets insulation and spreads along the deck. In MyBuilder's 2026 repair guide, minor roof repairs run £100 to £300 and major ones start at £2,500. The gap between those figures is largely a gap in how long the fault was left.
Predictable spend suits a lease
An agent running a service charge, or a landlord with a repairing lease, needs numbers that can be explained to someone else. A programme turns a lumpy emergency bill into a line that can be forecast and justified.
Evidence for later
When a roof is dated, photographed and logged year after year, a decision about replacement is made on evidence. It is also far easier to resolve a dispute about who should pay for what, because the condition of the roof at each date is on file.
What goes into a planned inspection cycle
A programme is built from visits of different weight. Not every visit needs to be a full survey, and not every roof needs the same pattern.
| Visit | When | What it covers |
|---|---|---|
| Full inspection | Once a year | Whole roof, with photographs and a written report |
| Clear and check | After leaf fall, and mid-year on tree-lined sites | Outlets, gutters, valleys and laps, with a quick look for new damage |
| After-event check | After a named storm or reported damage | Targeted look at edges, flashings, rooflights and loose items |
| Specialist survey | When a question arises | Moisture mapping, drone or thermal imaging on a suspect area |
The annual inspection
This is the anchor. The roof is walked or viewed, if safe to do so, and every element is checked: coverings, laps, fixings, flashings, upstands, outlets, gutters, rooflights, plant bases and cabling routes. Photographs are taken and numbered against a plan.
The tidy-up visits
Debris is the commonest cause of avoidable trouble. Leaves and silt stop outlets, then water builds up, loads the roof and pushes through weak points. Clearing is brief, inexpensive and the most effective item in the programme.
What the work does not include
A maintenance visit is not a re-roof in instalments. If it finds the covering has nothing left, the report says so and puts the options to you, instead of continuing to patch.
Keeping a roof file: what to record and why
The best programme in the world is wasted if its findings are lost. A roof file is the thing that outlasts any single contractor, agent or tenant.
The core contents
A useful file holds a plan of the roof showing each area and its covering, the date and type of each past repair, photographs of each inspection, a list of penetrations and plant, a record of rooflights and fragile areas, and any guarantee papers for earlier work. Our guide to fragile roofs and safe access explains why the fragile-area record in particular should be handed to every person who goes up.
A consistent set of photographs
Photographs taken from the same points each year let you see change. A stain that has grown, a lap that has lifted a few millimetres more or a patch that has failed shows up when two pictures are held side by side. We number the photographs against the plan so that a reader who was not on site can follow them.
Defect register
Each fault is logged with a location, a description, a priority and, once dealt with, a date and the work done. The register makes it clear what has been fixed, what is waiting and what has been watched without action. It also stops the same fault being reported afresh every year.
Who holds the file
For a managed estate, the agent holds the master copy and the contractor holds a working copy. When the contractor changes, the file passes on. A roof with no records is a roof where every new contractor starts from zero.
Sorting findings into priorities
An inspection report that lists thirty defects with equal weight is not much help to anyone paying the bill. A good report sorts them.
Urgent
Anything letting water into the building now, or creating a danger: a failed rooflight, a loose sheet, a damaged edge, a blocked outlet over a flat roof.
Soon
Faults that are not leaking but will, if left through the next winter: lifting laps, failed sealant, cracked flashings, damaged gutters and early signs of corrosion. These form the heart of the planned work and are grouped into one visit where we can. Our guide to cut-edge corrosion shows what early treatment of metal sheets involves.
Watch
Conditions that are acceptable now but need monitoring: minor surface crazing, a small area of ponding, a stain that has not changed since last year. They go on the register and are re-checked.
Plan
Items that point to a larger decision, such as a covering nearing the top of its lifespan range or an insulation layer that is likely to be wet. These are the ones to carry into the budget as a future capital item, rather than pretending they will go away.
Grouping saves money
Getting access in place, be it a platform, scaffold or edge protection, takes a big slice of many commercial budgets. Fixing four small things on one visit costs a good deal less than four separate trips.
Budgeting for roof upkeep on a managed estate
Roof costs split into three groups, and a budget that keeps them apart is easier to defend.
Fixed annual items
These cover inspections, clearing and minor repairs. MyBuilder's 2026 roof inspection guide gives a range of about £150 to £500 for a survey, with standard inspections around £150 to £250, drone surveys £200 to £400 and thermal surveys £300 to £500. Cleaning is priced by area, with MyBuilder's 2026 figures starting from about £300. These are national ranges rather than Supreme prices, and the right allowance for your estate depends on its size, roof types and access.
Variable repair allowance
Some repairs will arise each year, from storm damage and ordinary wear. A sensible allowance is built from the defect register. MyBuilder's 2026 repair guide quotes about £150 to £1,500 for typical repairs and £500 to £1,500 for storm fixes. Treat such figures as a context for your own history, which is a better guide than any average.
Capital items
When the register shows a covering heading toward replacement, move it into a longer-term plan. MyBuilder's 2026 guidance on full re-roofing gives typical national figures for domestic roofs, which are a poor guide to a commercial building. Commercial re-covering is quoted from a survey. If a sinking fund exists for the estate, this is what it is for.
Prices published first
Planned work is quoted in writing, with access, labour, materials and waste all covered. Your quote shows VAT.
Making a programme fit different buildings
One schedule does not suit every building. The pattern changes with the roof type, the site and the occupiers.
Flat and felt roofs
Flat roofs depend on drainage. They call for more frequent clearing, close attention to outlets and upstands and a look at ponding after rain. Our guide to built-up felt roofs explains the faults to watch for.
Metal and sheeted units
Industrial units with profiled steel need the laps, fixings and cut edges checked, and the rooflights treated as the likely weak points. Annual checks can catch rust early.
Older and historic buildings
Mills, warehouses and converted buildings carry mixed roofs, with valleys, parapets, lead and timber that are hard to access. Our guide to historic mill roofs in Stroud deals with those. For a listed building, check with Stroud District Council's planning team before assuming consent is not needed.
Sites with trees
Buildings near mature trees need more visits in autumn, as outlets block quickly. In Stroud's wooded valleys, a unit tucked below a hanger of beech and oak needs its gutters and valleys looked at more often than one on open ground.
Multi-let buildings
Where several tenants share a roof, the programme should say who gives access, how tenants are told and who pays. Our answer on overlaying a commercial roof may become relevant if the records show the covering is tired but the structure beneath is sound.
Setting up a programme with Supreme Roofing
We start with a survey, which fixes the baseline. We photograph your own roof, record its condition and mark fragile areas, and from that we write a proposal: how often we would visit, what each visit covers and what each costs.
What you receive
After each inspection, a report with numbered photographs, a prioritised defect list and a recommendation for each item. Urgent matters are raised straight away, without waiting for the report. If work is needed, a written quote follows.
Where repairs need approval
If work on a particular building needs consent, such as listed building consent, we explain what is needed. Where Building Regulations apply, we handle the notification. For most repairs on a like-for-like basis, no application is needed, but the position goes in writing rather than being left to assumption.
Guarantee and tidy site
Our 10-year workmanship guarantee comes in writing and covers the work we have done, not other trades or later damage. Our waste leaves with us.
