Catch a Commercial Roof Leak Before It Shuts Your Doors
A commercial roof rarely fails overnight. Spot the early signs and a repair often does the job, before water reaches your stock or wiring.
Keep an eye out for these:
- Standing water still sitting on a flat roof two days after rain
- Damp patches or brown stains spreading across ceiling tiles
- Blistered, split or lifting felt along seams and edges
- Rust streaks or bubbling on a metal or profiled sheet roof
- Blocked gutters and outlets backing water up onto the deck
- A musty smell or damp air inside a storeroom after heavy rain
- Daylight or drips around rooflights, vents and upstands
Water travels once it gets in. A drip in one corner often starts from a failed joint several metres away, following the fall of the deck. Left alone, that water soaks insulation, rots timber and finds its way to light fittings and sockets. A quick survey traces it back to the real source. Guess at the fix and you pay twice.
Repair, Refurbish or Replace — You Get the Honest Route
One failed seam does not mean the whole roof is finished. A localised split, a blocked outlet or a tired upstand is usually a straightforward repair. Widespread cracking, saturated insulation or a deck that flexes underfoot points further, toward a coating overlay or a full replacement.
Here is the plain version. A repair fixes an isolated fault fast and cheap. A refurbishment, usually a liquid coating or overlay, seals the whole surface and buys another ten to twenty years without a full strip-off. A replacement is the route once the roof is past saving. The table below sets the three side by side, with real figures.
| :-: | :-: | :-: | :-: |
| Option | Typical cost | Disruption to trade | Best for |
| Repair (localised) | £400–£1,500 for most small jobs | Low — often a day, little downtime | Isolated leaks, split seams, blocked outlets, storm damage |
| Refurbishment (coating / overlay) | £40–£90 per m² | Medium — works around trading, no strip-off | A sound but tired roof, saving 50–70% versus a new one |
| Full replacement | £75–£120+ per m² | High — strip-off, staged to limit closure | Failed decks, soaked insulation, roofs past economic repair |
We check the whole roof before we recommend a route. A free drone survey shows the outlets, laps and flashings a ground-level look always misses. You get the footage, not just our word. Around Kibworth Beauchamp and Great Glen we often find a coating adds years to a roof a rival had written off for replacement.
Flat Roof Leaks on Business Premises — Found Fast, Fixed Right
Most commercial roofs in this area are flat or low-pitch, and most leaks start at the same weak points. Joints, upstands, outlets and old repairs are where water finds a way in first.
Common failure points we trace:
- Splits and open laps where felt or single-ply sheets meet
- Perished sealant around vents, pipes and plant equipment
- Ponding water that sits and works away at the membrane
- Rusted or lifted flashings at parapet walls and upstands
- Cracked GRP or asphalt at movement joints and corners
Finding the source matters more than the patch itself. Water enters at one point and shows up at another, so chasing the stain inside rarely leads you to the fault. Our drone survey maps the whole surface, then we cut in a lasting repair using a system matched to your existing roof. You can read more about our full Commercial Roofing service, and the same principles cover a smaller Flat Roof Repair on a shop or office.
Roof Coatings and Overlays — Add Years Without a Full Strip-Off
A tired roof does not always need ripping off. A liquid coating goes on cold over the existing surface, sealing every joint and lap into one seamless skin. It suits felt, asphalt, single-ply and most flat roof substrates.
The appeal for a business is simple. A coating runs roughly £40 to £90 per square metre, against £75 to £120 or more for a full replacement. That is a saving of half to two thirds, with warranties on many systems reaching twenty years. Your unit stays open while the work goes on above.
It is not right for every roof. The deck must be sound, and any wet insulation has to come out first, or the fault stays trapped underneath. That is why the survey comes before the recommendation. For an independent view on getting the most from a difficult roof, this Building magazine feature on fixing difficult roofs is a useful read. We only quote a coating when it is genuinely the smart call for your building.
Planned Maintenance Keeps Small Faults From Becoming Big Bills
The cheapest commercial roof repair is the one you never need. A blocked outlet cleared in autumn saves a flooded stockroom in January. Planned maintenance catches those small faults on a schedule you can budget for.
A sensible maintenance routine covers:
- Two inspections a year, usually spring and autumn
- Extra checks after storms or long spells of heavy rain
- Clearing gutters, outlets and hoppers before they back up
- Resealing tired flashings and upstands before they let go
- A written report so you know the roof's real condition
Planned upkeep works out far cheaper than emergency call-outs. It also keeps a paper trail of the roof's condition, which helps at lease renewal or a building sale. Around Fleckney and Husbands Bosworth we look after several units on a regular schedule, so faults get spotted while they are still small and cheap.
We Work Around Your Trading Hours, Not the Other Way Round
Downtime is the hidden cost of a roof leak. A closed section, a soaked stockroom or a slip hazard on the shop floor all cost you money the invoice never shows. We plan the work to keep your business running.
That means staging repairs section by section, so no area closes longer than it must. Where a job would disrupt customers or staff, we work early, late or at weekends to fit around you. You get a realistic timeframe before we start, and you know who is turning up each day. Keeping your doors open is part of the job, not an afterthought.
What Commercial Roof Repair Really Costs in Market Harborough
Cost comes down to the fault, the roof size and access to it.
As a general guide, a small localised repair on a commercial flat roof runs roughly £400 to £1,500. A liquid coating or overlay works out at around £40 to £90 per square metre. A full replacement lands at £75 to £120 or more per square metre. Larger industrial or retail jobs can reach £5,000 to £15,000 once the whole roof is involved.
What moves a price up or down:
- **Roof size and layout*— more outlets, upstands and plant means more labour per square metre
- **Access*— a roof needing scaffold or a cherry picker costs more than one reached safely by ladder
- **Deck condition*— rotten timber or corroded sheets add cost before any new covering goes down
- **Wet insulation*— soaked boards must come out, which typically adds £30 to £50 per square metre
- **Out-of-hours work*— weekend or evening jobs to avoid closing your unit carry a premium
These are general market ranges for 2025 and 2026, not a quote for your roof. Two units the same size can price very differently once access, deck condition and trading hours are factored in. The only way to a firm figure is a proper survey — which is exactly what our free drone survey gives you, followed by a clear written price with nothing added later. A fixed price needs a survey.

Got Questions?
Your Commercial Roof Repair Questions, Answered Properly
How much does commercial roof repair cost?
A small localised repair on a commercial flat roof usually runs between £400 and £1,500. A coating or overlay works out at around £40 to £90 per square metre, while a full replacement sits at £75 to £120 or more. Larger industrial and retail jobs can reach £5,000 to £15,000 once the whole roof is involved. The final figure depends on the fault, the size and access, so a free drone survey gives you an exact written price. A fixed price always needs a survey first.
Should I repair, refurbish or replace my commercial roof?
It depends on how far gone the roof is. An isolated leak or split seam is a repair. A sound but tired roof suits a coating or overlay, which adds ten to twenty years for half to two thirds the cost of a new one. A failed deck or soaked insulation means replacement. We survey the whole roof first, then give you the honest route rather than the biggest invoice. You see the drone footage and decide with the facts in front of you.
Can you fix a roof leak without closing my business?
In most cases, yes. We stage the work section by section, so no area of your premises closes longer than it has to. Where a repair would disrupt customers or staff, we work early mornings, evenings or weekends to fit around your trading hours. You get a clear timeframe before we start, so you can plan around it. Keeping your doors open is part of how we work.
What is a roof coating, and will it work on my roof?
A liquid coating goes on cold over your existing roof, sealing every joint into one seamless waterproof skin. It works over felt, asphalt, single-ply and most flat roof surfaces, and can add ten to twenty years of life. The catch is that the deck must be sound and any wet insulation has to come out first. That is why we survey before recommending it. When the roof is right for a coating, it saves you a full strip-off and keeps your unit open.
How often should a commercial roof be inspected?
At least twice a year, normally spring and autumn, with extra checks after storms or long spells of heavy rain. Regular inspections catch small faults, like a blocked outlet or a tired flashing, before they turn into a flooded stockroom. Planned maintenance costs far less than emergency call-outs over time. It also builds a record of the roof's condition, which helps at lease renewal or a sale. We offer maintenance on a schedule you can budget for.
Who is responsible for a commercial roof leak, the landlord or the tenant?
That depends on your lease, so check the repairing clauses first. On a full repairing and insuring lease, the tenant usually carries roof repairs, while other leases keep that with the landlord. Either way, a leak needs dealing with fast before the damage spreads to stock and fittings. We are happy to survey and quote for whoever holds the responsibility. A clear written report often settles who pays for what.
How long does a commercial roof repair take?
A localised leak repair is often a single day, weather allowing. A coating or overlay across a full roof usually takes several days, depending on the size and access. A full replacement takes longer and is staged to limit any closure. We give you a realistic timeframe before work starts, not an optimistic one designed to win the job. You will always know roughly how long the crew will be on site.
Do you offer planned maintenance contracts?
Yes. We look after commercial roofs across the Harborough District on a regular schedule, with inspections twice a year and after major storms. Each visit covers clearing outlets and gutters, checking flashings and upstands, and a written report on the roof's condition. It keeps small faults from becoming big bills and spreads the cost across the year. Call us and we will set up a schedule that suits your building and budget.
