Tate & Sons Roofing handles flat roofing in Market Harborough and the wider Harborough District, from a leaking garage to a full commercial flat roof.
This page walks you through EPDM rubber, GRP fibreglass and felt, what each really costs, repair versus replacement, planning rules and what a fitting day looks like. Start with a free drone survey and a written quote before any work begins — no scaffold just to take a look, and no charge either way.

Spot the Early Warning Signs Before Water Reaches Your Ceiling
A flat roof rarely fails without notice. Catch the signs early and a repair often does the job, before the deck or ceiling gets involved.
Watch for these:
- Standing water still sitting there two days after rain
- Cracks, blisters or lifting felt along the edges and seams
- A ceiling stain that spreads a little after every downpour
- Green algae or moss holding damp against the surface
- A soft or spongy feel underfoot near the edges or upstands
- Damp or daylight around a rooflight or skylight upstand
- A musty smell in the room below that only shows after rain
Not every drip is a leak. On a cold, still morning a flat roof can drip from the underside even when it has not rained. Warm, moist air inside meets a cold deck and turns to water. A leak tracks with the weather; condensation shows up regardless of it. The fix for each is completely different, which is why a proper inspection comes before anyone reaches for sealant. Guess wrong and you pay for a repair that never solves the real problem.
Repair or Replace? You Get a Straight Answer, Not the Biggest Invoice
One cracked seam rarely means the whole roof is finished. A single split, a lifted edge or a failed upstand is usually a flat roof repair, not a re-cover. Widespread blistering, a deck that flexes underfoot, or the same patch failing twice points to replacement instead.
We see this pattern on older extensions around Lubenham and Foxton. A felt roof gets patched two or three times over the years, while nobody addresses the ponding that caused the first crack. Patching the symptom again buys a season or two, and you end up paying for three small jobs instead of one proper one.
We check the whole roof before recommending either route. A free drone survey shows the full picture — the upstands, outlets and edge trims that a ground-level look always misses. You get the footage, not just our word for it. Most like-for-like flat roof replacements in England do not need planning permission. Building Regulations sign-off does apply once you upgrade insulation or replace more than a quarter of the roof, which covers most full re-covers. We handle that paperwork so it never lands back on you.
EPDM, GRP or Felt — Which Flat Roof System Actually Suits Your Home?
Three systems cover almost every flat roof in this area. Each suits a different job, budget and lifespan. In short: felt is the cheapest upfront and best for small garages; EPDM rubber is the strong-value all-rounder for most extensions, with few joints and a 20-plus year life; GRP fibreglass costs the most but gives a fully seamless, walkable finish that lasts longest. The right choice depends on the roof size, how it is used, and how long you want it to last. A survey settles it in plain terms.
Ryan Tate, our project manager, fits EPDM and GRP systems day in, day out. He will walk you through which one suits your roof, your budget and how long you want it to last — in plain English, not sales jargon.
| :-: | :-: | :-: | :-: |
| System | Typical cost (per m²) | Typical lifespan | Best for |
| Felt (built-up) | £40–£70 | 15–20 years | Smaller garages and outbuildings on the tightest budget |
| EPDM rubber | £50–£90 | 20–30 years | Most extensions and garage roofs; few joints, strong value |
| GRP fibreglass | £80–£130 | 30–40 years | Walkable terraces, complex shapes, the longest life |
- **EPDM rubber*is a single-ply membrane bonded down in large sheets. Few joints, and it stands up well to UK weather cycles. Good value over the life of the roof, and the system we fit most on standard extensions.
- **GRP fibreglass*goes on as a liquid and cures solid, so the finished surface has no seams at all. Well suited to a roof used as a walkway or terrace, or anywhere a fully watertight finish matters most — our GRP fibreglass roofing page covers it in full.
- **Felt (built-up roofing)*is layers of bitumen felt bonded together. The cheapest system upfront, and still a sound choice on smaller garages and outbuildings where budget decides it.
What a New Flat Roof Really Costs in Market Harborough
Cost comes down to three things: material, size and access.
As a general guide, felt runs roughly £40–£70 per square metre, EPDM rubber £50–£90, and GRP fibreglass £80–£130. For a typical 25–30m² garage or extension roof, that works out at around £1,200–£3,500 for felt, £1,800–£3,200 for EPDM, and £2,400–£4,200 for GRP.
What pushes a price up or down:
These are general market ranges, not a quote for your roof. Two roofs the same size can price very differently once access, deck condition and insulation 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.
- **Roof size and shape*— more corners, upstands and pipe penetrations mean more labour per square metre
- **Access*— a roof reached by ladder costs less to scaffold than one boxed in behind an extension
- **Deck condition*— rotten timber underneath typically adds £500–£1,800 before the new covering goes on
- **Insulation upgrade*— bringing a re-cover up to current Building Regs standard usually adds £450–£950
- **Stripping off*— how many old layers have to come off before the new system goes down
From Strip-Out to Sign-Off: What Happens on Fitting Day
A flat roof re-cover follows the same order on every job:
- Old covering stripped back to the deck
- Deck checked and any rotten timber replaced
- Insulation upgraded to current standards where needed
- New membrane or felt fitted and sealed at every edge and upstand
- Flashings and trims fitted to shed water cleanly
- Site cleared and the finished roof checked before we leave
Most garage and extension roofs take one to three days, weather allowing. Larger commercial flat roofs or a full house re-cover take longer. We give you a realistic timeframe before work starts, not an optimistic one designed to win the job. You will know who is turning up and roughly how long they will be there.
Warm Roof or Cold Roof — Get the Insulation Right and Forget Condensation
Roofers in Market Harborough often mention a “warm roof” versus a “cold roof,” and the difference matters. A warm roof has insulation fitted above the deck, so the structural timber stays warm and dry. A cold roof puts insulation between the joists below the deck, leaving the timber exposed to cold air and more prone to condensation.
Most re-covers we fit now use a warm roof build-up. Current Building Regulations expect a proper insulation standard on any re-covered flat roof. Getting this right at the fitting stage heads off condensation for good, rather than storing up a problem for the next owner. It always costs more to fix later, once staining or a musty smell has already set in below.
A Few Minutes a Year Keeps a Flat Roof Working for Decades
A flat roof lasts longest when small faults get caught early. None of this needs a specialist — just a look, a couple of times a year.
- Clear leaves and debris from outlets each autumn
- Check for standing water a day or two after heavy rain
- Look over flashings and upstands once a year
- Book a free drone survey if you spot any warning sign above
For an independent reference on flat roof coverings and standards, the Liquid Roofing and Waterproofing Association’s technical guidance is a useful place to read up before you commit to a system.
Why Market Harborough Homeowners Call Tate & Sons First
You are not just buying a membrane — you are buying whoever fits it. Ryan Tate, our project manager, joined the trade full-time after his NVQ Level 3 in Roofing, and specialises in the exact systems on this page: full re-roofs, EPDM rubber and GRP fibreglass. He is part of the same crew that turns up to fit your roof, not just the man who quoted it.

Between us we carry over 45 years of combined experience, hold NVQ Level 2 and 3 qualifications in Roofing Occupations, and keep CSCS cards and NFRC trade-body membership. Hannah Freeman, our office manager, keeps you posted from the first phone call through to final inspection, so nothing slips between the drone survey and the finished roof.

Got Questions?
Your Flat Roofing Questions, Answered Properly
Is it safe to walk on a flat roof?
Only if it is designed and specified for foot traffic. Standard felt and EPDM roofs are not built to take regular walking, and the membrane can split or the deck flex under weight it was never meant to carry. If you want a roof you can use as a terrace, that has to be specified and fitted differently from the start, usually as a GRP or reinforced system. Treat any flat roof with care, and call us before going up, especially after recent repair work.
Why is water pooling on my flat roof?
Ponding usually means the roof has lost its fall, a drain has blocked, or the deck has sagged over time. A little standing water after heavy rain that clears within a day is often normal. Water sitting more than 48 hours puts extra strain on the membrane and speeds up wear at that spot. It is worth a survey rather than waiting it out and hoping it drains on its own.
Do I need planning permission to replace a flat roof?
Most like-for-like replacements do not need planning permission in England. Building Regulations approval does apply once you upgrade insulation or replace more than 25% of the roof, which covers most full re-covers we carry out. Listed buildings and some conservation areas are the exception and need consent first. We handle the Building Control paperwork as part of the job, so you are not left chasing forms or worrying about compliance later.
Why does my flat roof drip inside even when it isn’t raining?
That is almost always condensation, not a leak. Warm, moist air from inside meets a cold roof deck and turns to water on the underside, which then drips exactly like a leak would. A proper warm-roof insulation upgrade, with insulation above the deck rather than below it, is usually the permanent fix. Treating it as a leak and re-sealing the outside will not solve a condensation problem, and often makes the trapped damp worse.
How much does a new flat roof cost in Market Harborough?
As a general guide, felt starts around £40 per square metre, EPDM around £50, and GRP around £80, with the final figure set by size, access and deck condition. A typical garage or extension re-cover lands somewhere between roughly £1,200 and £4,200 depending on the system. A free drone survey gives you an exact written price rather than a rough estimate over the phone. A fixed price always needs a survey first.
Will a flat roof cause problems with my mortgage or a survey?
Surveyors do flag flat roofs nearing the end of their life, particularly on extensions, since they carry a shorter typical lifespan than a pitched tiled roof. A recent re-cover with paperwork and a warranty to show for it, backed by a drone survey report as evidence of current condition, generally gives a buyer or lender enough confidence to proceed. It can head off a retention or a last-minute chip at the price.
Does a conservation area restrict which flat roof covering I can use?
It can. Parts of Great Bowden and Foxton sit within areas where the local planning authority takes a closer look at visible roofing changes, especially where a flat roof shows from the street or affects a period property. We check this before quoting, so there are no surprises once work is scheduled, and we can advise which systems tend to be acceptable in those areas.
What happens if you find rotten timber once the old covering is off?
We replace it before the new system goes on — there is no way to fit a lasting flat roof over a soft or rotten deck. This is exactly why our cost guidance includes a typical range for deck repairs, so it is not an unpleasant shock if it turns up. We always show you the problem and agree the extra work before we proceed, rather than adding it to the bill afterwards.
