Roof Coatings and Sealing Market Harborough
Roof coatings and sealing in Market Harborough get talked up a lot, and not always fairly. A good liquid coating adds years to a sound flat roof. A bad one, sold hard on a failing roof, just hides the fault and empties your wallet. Tate & Sons Roofing gives you the straight version, then a coating only where it genuinely earns its place.
This page sorts real flat-roof liquid systems from the over-sold tile sprays you may have read warnings about. You will see what each coating type costs, how long it lasts, when sealing is the right call, and when a re-roof is the honest one. It starts with a free drone survey and a written price, with nothing added later. Coatings sit alongside the wider work we handle as a roofing contractor across Market Harborough.

Do Roof Coatings Actually Work? The Honest Answer First
Yes, on the right roof, applied the right way. A quality liquid coating cures into a seamless, flexible film that sheds water and stands up to UK weather. On a flat roof with a sound deck, it can add ten to twenty years of life for a fraction of a full re-cover.
The catch sits in those two conditions. The roof has to be structurally sound, and the surface has to be prepared properly first. Coat over damp, moss or a failing membrane and the film blisters, peels and traps water underneath. That is where coatings earn their mixed name, and why we survey before we ever quote one.
So a coating is a genuine repair on a tired but solid roof. It is not a magic fix for a roof that has already given up. We tell you which of the two you have, in plain terms, before you spend a penny.
Flat-Roof Liquid Systems Versus Tiled-Roof Sprays — Know the Difference
These two jobs get lumped together, and they should not be. A flat-roof liquid coating is a proven waterproofing system, laid to a set thickness over a prepared deck. It seals joints, upstands and outlets that a sheet membrane struggles to reach. Done well, it is real, lasting work.
Spray-coating pitched tiles is a different animal. Trading Standards teams across the country have warned about it for years. Salesmen posing as surveyors pressure homeowners into jet-washing and spraying sound tiles, often for thousands of pounds, when the roof needed nothing. Moss on a tile does little harm, and a hard coating can trap moisture and speed up wear.
We do not sell that. If your tiles just need cleaning, a straight Roof Cleaning or Moss & Algae Removal visit costs far less and does the job. We never coat a clay or slate roof, and we never dress up a re-roof as a spray. You get the cheaper, correct answer every time.
Which Coating Suits Your Flat Roof?
Four liquid systems cover almost every flat roof around here. Each has a job it does best. In short: acrylic is the budget refresh and reflective topcoat on a sound roof; aluminised bitumen re-coats an old felt roof cheaply; silicone shrugs off ponding water and lasts well; polyurethane liquid membrane handles fiddly detail and gives the longest life. The right pick depends on the roof, how water sits on it, and how long you want it to hold.
Ryan Tate lays these systems himself, so his advice comes off the roof, not out of a brochure. He will match the coating to your roof, your budget and how long you want it to last, in plain English. No pressure, no upsell.
| :-: | :-: | :-: | :-: |
| Coating type | Typical cost (per m²) | Typical lifespan | Best for |
| Acrylic | £26–£48 | 10–15 years | Budget refresh and a reflective topcoat on a sound roof |
| Aluminised bitumen | £22–£38 | 5–10 years | Re-coating a tired felt roof at the lowest cost |
| Silicone | £34–£68 | 15–20 years | Roofs that hold ponding water; strong weather resistance |
| Polyurethane liquid membrane | £32–£58 | 20–25 years | Detailed roofs, upstands and the longest waterproof life |
- **Acrylic*is water-based and easy to lay. It gives a clean, reflective finish that helps a roof run cooler. Best as a refresh on a roof that is sound but looking tired.
- **Aluminised bitumen*is the low-cost option for an old felt roof. It buys a few more years and reflects heat, though it needs re-doing sooner than the others.
- **Silicone*handles standing water better than most. It stays flexible through hot and cold spells and holds up where rain tends to pond.
- **Polyurethane liquid membrane*is the workhorse for detailed roofs. It seals around pipes, outlets and upstands, and gives the longest service life of the four.
What Roof Coatings and Sealing Cost in Market Harborough
Cost comes down to three things: the coating you choose, the roof size, and how much prep the surface needs.
As a general guide, aluminised bitumen runs roughly £22–£38 per square metre, acrylic £26–£48, polyurethane liquid membrane £32–£58, and silicone £34–£68. For a typical 100m² flat roof, that works out at around £2,200–£3,800 for aluminised bitumen, £2,600–£4,800 for acrylic, £3,200–£5,800 for polyurethane, and £3,400–£6,800 for silicone.
What moves the price up or down:
- **Surface prep*— a mossy or dirty roof needs cleaning and drying before any coating goes near it
- **Coating type and thickness*— a longer-life system means more material laid to a set depth
- **Roof detail*— pipes, outlets and upstands take extra time to seal by hand
- **Access*— a roof reached by ladder costs less to set up than one boxed in behind an extension
- **Repairs first*— splits, blisters or a soft patch of deck must be sorted before sealing
These are general market ranges, not a quote for your roof. Two roofs the same size can price very differently once prep, detail and repairs are counted in. The only way to a firm figure is a proper look, 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.
How We Clean, Prime and Seal a Flat Roof, Step by Step
A coating only lasts if the groundwork is right. Every job we do follows the same order:
- Survey the roof and check the deck is sound underneath
- Clean off moss, dirt and loose material, then let the surface dry fully
- Repair any splits, blisters or failed seams before coating starts
- Prime the surface so the coating grips properly
- Lay the liquid system to the correct thickness, sealing every joint and upstand
- Reinforce around outlets and pipes, then check the finished film before we leave
Most coating jobs take one to three days, weather allowing. A coating needs dry conditions to cure, so we plan around the forecast rather than rushing it in the wet. You will know who is turning up and roughly how long they will be on site. Homes in Lubenham and Foxton often need an extra prep day when moss has taken hold, and we build that in up front.
How Long a Coating Lasts — and When a Re-Roof Is the Honest Call
A well-laid coating lasts anywhere from five to twenty-five years, depending on the system and the state of the roof beneath it. Silicone and polyurethane sit at the top of that range. A budget bitumen re-coat sits at the bottom. Good prep is what decides where your roof lands.
Here is the line we will not cross. A coating seals a surface. It cannot rebuild a rotten deck, replace soaked insulation, or fix a roof that has failed structurally. Where the deck flexes underfoot or water has been getting in for years, a coating just paints over the problem. In those cases we quote a re-cover instead, because that is the repair that actually holds.
For an independent reference on liquid systems and standards, the Liquid Roofing and Waterproofing Association’s technical guidance is a solid place to read up before you commit. It sets out the British Standards and third-party certificates a genuine system should meet.
A Little Care Each Year Keeps a Coated Roof Sealed
A coated 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 the coating around upstands and pipes once a year
- Book a free drone survey if you spot a crack, blister or bare patch
A coating that gets a quick check now and then can be topped up long before water finds a way through. Leave it untouched for a decade and small faults grow into a full re-coat. A few minutes a year is the cheapest insurance a flat roof has.
Why Market Harborough Homeowners Call Tate & Sons First
You are not just buying a coating — you are buying whoever lays it and whoever advises you first.

He is part of the same crew that turns up to seal your roof, not just the man who quoted it.
Founder Michael Tate started his apprenticeship at sixteen and built Tate & Sons on one rule: survey the roof properly, then give honest advice, even when honest advice means walking away from a sale. That is why we will tell you a clean beats a coating, or a re-roof beats both, when that is the truth. 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.

Got Questions?
Your Roof Coating Questions, Answered Properly
Do roof coatings actually work?
On the right roof, yes. A quality liquid coating cures into a seamless, flexible film that sheds water and resists UK weather. On a flat roof with a sound deck, it can add ten to twenty years of life for a fraction of a re-cover. The results depend on preparation, though. Coat over damp, moss or a failing membrane and it blisters and peels, which is why we survey before we quote.
Are roof coatings worth the money?
They are worth it when the roof is structurally sound and just needs a fresh seal. In that case a coating costs far less than a new roof and buys real years. They are poor value on a roof that has already failed, where they only hide the problem. The honest test is the survey, and we give you that free before any decision.
How long does a roof coating last?
Anywhere from five to twenty-five years, depending on the system and the surface it goes onto. Aluminised bitumen sits at the shorter end, silicone and polyurethane at the longer. Good prep and the correct thickness make the biggest difference to how long it holds. A yearly check and the odd top-up can stretch that life further still.
Can you spray-coat roof tiles like the adverts offer?
We do not, and we would steer you away from it. Trading Standards teams have warned for years about tile-spraying sold under pressure, often on roofs that needed nothing. Moss does little harm to a tile, and a hard coating can trap moisture and speed up wear. If your tiles look tired, a clean or moss removal costs a fraction of a spray and does the job properly.
Will a coating stop my flat roof leaking?
If the leak comes from a tired but sound surface, a proper liquid system can seal it for years. If the deck is rotten, the insulation soaked, or water has tracked in for a long time, a coating only masks it. We find the real cause with a drone survey first, then tell you whether sealing or a re-cover is the fix that lasts.
Is a roof coating a substitute for a new roof?
No, and anyone claiming otherwise is overselling. A coating seals a surface; it cannot rebuild a failed structure. On a roof with a soft deck, a sagging fall or years of water damage, a re-cover is the honest answer. We quote the repair the roof actually needs, not the one with the bigger margin.
How much does roof coating cost in Market Harborough?
As a general guide, aluminised bitumen starts around £22 per square metre, acrylic around £26, polyurethane around £32, and silicone around £34, with the final figure set by prep, detail and any repairs. A typical 100m² flat roof lands somewhere between roughly £2,200 and £6,800 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.
Why do some roof coating firms get such a bad name?
Because a handful sell hard on roofs that never needed the work. Commission salesmen pose as surveyors, jet-wash sound tiles, and charge thousands for a coating that can do more harm than good. Genuine flat-roof liquid systems are nothing like that, and are backed by British Standards. We survey honestly, quote in writing, and only coat where it genuinely helps.
