Repair or Replace? Choosing the Right Fix for Your Commercial Roof
Whether your commercial roof needs a repair or a full replacement usually comes down to three things: its age, how much of the surface is damaged, and how often you're already calling someone out. A roof under 10-15 years old with damage to less than a quarter of its surface is normally worth repairing. A roof past 15 years old, needing repeat call-outs, or with damage spreading across several areas is usually cheaper to replace than to keep patching. A free drone survey gives you a straight answer either way, not a guess based on what's easiest to sell.
Repair usually makes sense when:
- The roof is under 10-15 years old
- Damage covers less than around 25% of the total surface
- The deck (the timber or metal base under the membrane) is still sound
- You're planning to sell or relet the unit within the next few years
Replacement usually makes sense when:
- The roof is 15 years old or more
- You're calling a roofer out more than once a year for the same building
- Several systems are failing together — membrane, flashing, and insulation
- Energy bills are climbing because the insulation has stopped performing
If you run a warehouse, factory, or distribution unit rather than a shop or office, our industrial roof repair page covers the larger structural systems, liner panels, and rooflights those buildings typically need in more detail.
What's Really Causing Your Commercial Roof to Leak?
Commercial flat roofs fail in fairly predictable places. Knowing the usual culprits helps you describe the problem accurately when you call us.
- Ponding water — rain sitting in a dip for more than 48 hours, which breaks down the membrane faster than anywhere else on the roof
- Roof penetrations — the pipes, vents, and HVAC (heating and air conditioning) units fixed through the roof, where vibration and expansion work flashing loose over time
- Ageing flashing and upstands — the metal or membrane strips sealing joints and walls, which crack or lift as sealants age
- Foot traffic damage — splits and punctures where staff or contractors walk across the membrane to reach plant equipment
- Blocked outlets and gutters — leaves and debris that stop water draining, forcing it to find another way off the roof
- Movement at expansion joints — gaps built in to let a large roof structure move with temperature changes, which open up and let water through if the seal fails
What Happens Before We Touch Your Commercial Roof
Every commercial job starts with a clear picture of the roof and a plan that fits around your business, not the other way round.
- We carry out a free drone survey covering the whole roof, flashings, and penetrations — no scaffold needed just to look
- You get clear photos and an honest recommendation: repair, or replace
- We confirm who's responsible for the repair if you lease the unit, since many commercial leases put roof upkeep on the tenant under an FRI (Full Repairing and Insuring) arrangement
- We check whether the repair affects fire compartmentation — the fire-resisting barriers between roof sections — on larger or multi-let buildings, and flag anything needing Building Regulations sign-off
- We agree access and timing around your trading hours, including early, late, or weekend working where it matters
- You get a firm quote and a written scope before any materials arrive on site
A properly specified commercial repair follows the same principles set out in Building magazine's checklist for commercial roofing — materials tested to recognised standards, fire performance considered, and safe access built into the plan from the start. We work to the same standard on every job, whatever the size.
How to Check a Commercial Roof Repair Was Done Properly
A rushed commercial repair often looks fine from the ground and fails again within a season. Here's what a proper job should show.
- The repaired area sits flat and taut, with no ripples, bubbles, or soft patches underfoot
- Edges and upstands are fully bonded, not just tucked or dabbed with sealant
- You're given before-and-after photos, including anything found under the old membrane
- The written scope matches the work actually carried out, with no vague substitutions
- You receive a workmanship guarantee in writing, with the material and thickness used clearly stated
- Any sign-off your lease or insurer requires is provided as part of the paperwork, not chased up later
We back every commercial repair with a 10-year workmanship guarantee, so you've got something in writing beyond our word.
Stopping Leaks Before They Start: Commercial Roof Maintenance
Most commercial roof emergencies are preventable with a routine check twice a year.
- Book an inspection in spring and again in autumn, which is the schedule most manufacturers and industry bodies recommend for commercial roofs
- Clear outlets and gutters ahead of autumn leaf-fall, when blockages cause the most damage
- Check for standing water a couple of days after heavy rain — if it's still there, the fall (the roof's built-in slope) has likely dropped
- Have plant and HVAC penetrations checked whenever new equipment goes on the roof, since that's a common point of new leaks
- Set up a planned maintenance contract if you manage several units or a multi-let building, so inspections happen without you having to remember them
- Remove moss and algae from shaded corners, which hold moisture against the membrane and shorten its life
How We Repair a Commercial Roof Without Shutting Your Business
Speed matters as much as quality on a commercial job, because every day the roof's open is a day of disruption. Here's how a typical repair runs.
- Isolate and assess the specific area of damage, rather than opening up more of the roof than needed
- Strip back to a sound deck or membrane locally, replacing any wet insulation or rotten timber we find underneath
- Fit matching material with proper detailing at every penetration, upstand, and joint, since that's where most repairs fail first
- Test the repaired area for watertightness before we consider the job finished
- Clear the site and hand it back in an agreed window, typically the same day for a single leak or 1-3 days for a larger patch
- Work outside your trading hours on request, so a shop, restaurant, or office doesn't lose a day's business
Cost & Pricing Guidance
Commercial roof repair pricing across the UK for 2025/26 typically runs like this:
- Small repairs (a single leak, a section of flashing, a localised patch): £400-£1,000
- Larger repairs across several areas or a bigger commercial unit: £5,000-£15,000+
- Minor patch and flashing work on smaller premises: from around £250-£650
- Labour rates typically run £30-£45 per hour
- Full re-covering, where replacement is the better option: roughly £90-£200 per m², depending on the system specified
What pushes the price up or down: the extent of damage, how many separate areas need attention, access (scaffold and safety netting are often required by working-at-height rules even for a small patch), the condition of the deck underneath, and whether the repair needs to happen outside your trading hours.
As a rough guide, if repair costs are creeping past 15-20% of what a full replacement would cost, it's usually the point to have that replacement conversation instead of booking another patch.
These are general ranges, not a quote. A fixed price needs a survey — and our drone survey is free, with no obligation.
Comparison Table: Commercial Roofing Systems
| System | Typical Lifespan | Best For | Relative Cost |
|---|---|---|---|
| Built-Up Felt / Modified Bitumen | 15-20 years | Older commercial buildings, budget-conscious repairs and re-covers | £ (lowest) |
| EPDM Rubber | 30-40 years | Shops, offices, and smaller commercial units wanting low upkeep | ££ |
| TPO / PVC Single-Ply Membrane | 20-30 years | Larger retail and office roofs needing fast, wide-sheet installation | ££ |
| Standing-Seam Metal | 40-50 years | Prestige commercial premises and roofs with a strong pitch | £££ (highest) |
Single-ply membranes like TPO and PVC come as wide sheets rather than the narrower rolls used for EPDM, which means fewer seams to weld and faster coverage on a large retail or office roof. Built-up felt is laid in multiple bonded layers, giving useful redundancy if the top layer gets damaged, but it needs more frequent inspection than the other systems here. Standing-seam metal costs more to install but suits premises where appearance and a very long service life both matter.

Got Questions?
Your Flat Roofing Questions, Answered Properly
How much does commercial roof repair cost in the UK?
Most small commercial repairs cost £400-£1,000, while larger jobs across a bigger unit can run £5,000-£15,000 or more. Minor patch and flashing work on smaller premises sometimes starts as low as £250-£650. The final figure depends on the extent of damage, how many areas need attention, and whether scaffold or safety netting is required for access. A survey gives you an exact number rather than a general range.
How do I know if I need a repair or a full replacement?
It usually comes down to the roof's age and how much of it is damaged. A roof under 10-15 years old with damage to less than a quarter of the surface is normally worth repairing. A roof past 15 years old, or one you're calling a roofer out for more than once a year, is usually cheaper to replace outright than to keep patching. Our free drone survey tells you honestly which side of that line your roof sits on.
What causes most commercial roof leaks?
Ponding water, failed flashing, and roof penetrations for HVAC units and pipework cause the majority of commercial roof leaks. Ponding breaks a membrane down faster than any other single factor, especially where the roof's fall has dropped over time. Penetrations are a close second, because vibration and thermal movement work the seals around pipes and plant loose. Blocked outlets and worn upstands account for most of what's left.
How often should a commercial roof be inspected?
Twice a year, ideally in spring and autumn, plus a check after any severe storm. That schedule matches what most roofing manufacturers and industry bodies recommend for commercial buildings. Catching a lifted flashing or a blocked outlet at a routine visit is far cheaper than dealing with the leak it eventually causes. If you manage several units, a planned maintenance contract keeps this on schedule without you having to chase it.
Can commercial roof repairs be done without closing my business?
Yes, in most cases we can carry out repairs while you stay open and trading. We isolate the affected area, use access that keeps clear of customer or staff areas, and can work early mornings, evenings, or weekends where that suits you better. Larger jobs sometimes need a small area cordoned off below for safety, but full closure is rarely necessary for a repair. We agree the access plan with you before any work starts.
Who is responsible for commercial roof repairs — landlord or tenant?
It depends on your lease, but many commercial leases in Nottingham put roof repairs on the tenant under an FRI (Full Repairing and Insuring) arrangement. Some leases split responsibility by roof section or cap the tenant's liability for structural items. It's worth checking your lease before booking work, since this decides who should be paying and who needs to authorise it. We're happy to work directly with a landlord, managing agent, or tenant, whoever holds that responsibility.
Does a commercial roof repair need Building Regulations sign-off?
Small like-for-like repairs generally don't need Building Regulations notification. Larger repairs or re-covers, particularly on multi-let buildings, can trigger requirements around fire compartmentation — the fire-resisting barriers that stop flames spreading between units — and may need formal sign-off. We flag this during the survey stage so it's dealt with before work starts, not discovered afterwards.
Will a different contractor repairing my roof invalidate my existing warranty?
It can, depending on the terms of your original installer's warranty. Some manufacturer and installer warranties require any repair work to be carried out or approved by an accredited contractor to stay valid. Check your paperwork before booking a repair with a different company, and ask whoever you use to document the work clearly. We provide detailed photos and a written scope with every job, which helps protect your position either way.
Can commercial roof repairs be scheduled out of hours in Nottingham city centre?
Yes, we regularly schedule commercial repairs outside standard trading hours, including early mornings, evenings, and weekends. This matters most for city centre shops, restaurants, and offices where daytime access is restricted or disruptive to customers. Out-of-hours work sometimes carries a small premium, but for many businesses it's worth it to avoid losing a trading day. We agree timing as part of the quote, not as an afterthought.
