West London's roof repair specialists
Roof Repairs Hounslow
Watertight Roof Repairs Hounslow
Leak tracing, storm and vortex damage, chimneys, gutters, flat roofs and roofline across Hounslow and the boroughs around it
No roofs in Britain live like Hounslow's. Overhead, the world's busiest two-runway airport lands a plane a minute; underneath, London clay swells and shrinks with the seasons; and in between sits housing thrown up in two great bursts - Victorian terraces, then the enormous 1930s semi boom - now working through its tenth decade. Repairing that housing well is a specific local trade. It's ours, it starts with a free survey, and it ends with ten years in writing.
Start with the free survey
Pop your details in and we'll call you back to book the survey. It costs nothing, it obliges you to nothing, and if the honest verdict is that your roof needs no work, that verdict is exactly what you'll get.

Roof Replacement

Full details about roof replacement in HounslowWhat's above and what's below: the two forces on a Hounslow roof
Look up first. When Heathrow operates westerly - which is most of the time - every arrival descends over this borough, low enough over Isleworth and Hounslow that you can read the airline. Mostly that's just noise. Occasionally it's physics: the wake vortex spinning off a landing aircraft reaches the ground and lifts a patch of tiles off someone's roof on a windless morning. It's rare enough to sound like an excuse and real enough that Heathrow runs a formal Vortex Protection Scheme, repairing verified strikes free within blanket zones that stretch about 4km from the runway ends - across Cranford, Heston and a good deal of Hounslow proper. We're one of the few firms that treats vortex literacy as a basic job skill.
Now look down. Most of west London stands on London clay, a ground that swells through wet winters and shrinks hard in dry summers. Houses ride those movements, and their roofs keep the minutes: chimneys nudged fractionally off plumb, hairline openings at flashings and party-wall junctions, ridge lines with a gentle wave in them. Add the driest climate in Britain - the Heathrow climate station logs around 615mm of rain a year, half of what the western half of the country gets - and faults hide for years, surfacing only when a proper storm arrives to audit them.
The housing between those two forces arrived in bursts. The Victorians left terraces in central Hounslow and Isleworth; then the tube reached Hounslow West in 1925, the Great West Road opened in 1930, and the semi boom roofed square miles of Heston, Cranford, Whitton and Feltham inside fifteen years. That stock is now ninety, its nails and mortar retiring together, street by street. None of this makes these bad roofs - it makes them roofs with specific, knowable habits. Knowing them is the job.
Why Hounslow rings Watertight
- Repairs are the business, not the consolation prize. The £200 fix that works gets offered before the £8,000 one that also works - you'd be amazed how rare that ordering is.
- Every survey covers the loft as well as the slopes, because the underside of a roof records every leak it's ever had. Costs you nothing either way.
- You see photographs of the actual fault before you hear a price, and the diagnosis is yours to keep - take it to another firm and compare quotes on identical information.
- We know this patch's oddities cold: which streets sit in Heathrow's vortex blanket zones, which conservation areas care about your tile choice, which boroughs' rules apply where.
- Quotes come itemised with access on its own line, fixed in writing, and free of follow-up phone calls. A quote is information, not a siege.
"Most of the west London homeowners who come to us for a second opinion have been quoted for more work than their roof needs. The second opinion is free; the first one wasn't cheap."
From the enquiries Watertight Roof Repairs Hounslow handles
Six steps from worry to warranty
Every job walks the same road, and you can see all of it from the start.
Get in touch
Phone if it's urgent, the form if it's not. Describe what you've seen in your own words - we'll ask anything else we need.
We look, properly
Roof from height, loft from inside, camera in hand. Free, half an hour, and you're welcome to watch and ask questions.
Verdict with evidence
What's wrong, what caused it, photos to prove it - and an honest word on urgency, because plenty of faults can wait.
A price that holds
Fixed, itemised, in writing. Compare it anywhere. It doesn't creep and nobody rings you twice a week about it.
The repair, done right
Failed material off, matching replacements on, lead where lead belongs, fixings to modern spec. Site swept before the van leaves.
Proof and paper
Completion photos to your phone and the ten year written guarantee in your hand. That's the job closed - ideally for a decade.
The guarantee is a document, not a phrase
"All work guaranteed" costs nothing to say, which is why every van in west London says it. What matters is whether anything gets written down. Work arranged through Watertight Roof Repairs Hounslow comes with a 10 year workmanship guarantee as an actual piece of paper - dated, signed, specific to your job - handed over alongside the completion photos. Materials carry their manufacturers' own cover on top, which varies by product, so your paperwork names what applies to yours instead of waving at a number.
A guarantee that long is only affordable if the repairs don't come back - so it shapes how the work is done. Failed material comes off rather than getting covered over. Replacement tiles and slates go on with fixings specified for a roof that lives under the Heathrow approach, not the minimum the 1930s got away with. Junctions get lead. And anything we find that we can't fix that day gets photographed and said out loud, because surprises kept from you now become our problem within 10 years.
Plainly: if water gets back in through work we've done, we return and put it right at no cost, for a decade. Ask any firm quoting against us to match that in writing - it's an interesting conversation to watch.

One patch, four boroughs, four rulebooks
Our service area crosses four London planning authorities, and their boundaries follow century-old history rather than anything sensible like postcodes. When your job touches permissions, conservation areas or building control, which town hall owns your street stops being trivia - so we keep the map straight for you.
London Borough of Hounslow
Home turf - 28 conservation areas, the Heathrow approach overhead, and our base inside it on Southall Lane.
Hounslow, Brentford, Isleworth, Feltham
London Borough of Richmond upon Thames
The heritage heavyweight - protected views, riverside conservation areas, and roofs that expect matching slate.
Twickenham, Richmond
Ealing Council
The Queen of the Suburbs, including Brentham Garden Suburb's Article 4 direction - the strictest street rules on our patch.
Ealing
Hillingdon Council
The western flank - Metroland semis and factory-era terraces, and refreshingly few conservation complications.
Hayes, Uxbridge
Routine like-for-like repairs need permission from none of the four. Conservation areas, listed buildings and visible material changes are where paperwork begins - and if your job qualifies, you'll hear it from us at the survey, not from an enforcement letter.
Learn what your roof is telling you
Ten minutes of reading makes you a much harder customer to overcharge. We've written up the faults that actually occur on west London's roofs - slipped and delaminating tiles, tired flashings, powdered ridge mortar, ponding flat roofs, the lot - with what each looks like from the ground and a straight answer on how urgent it really is.
It also covers the two great decoys, condensation and failed gutters, which between them are responsible for half the unnecessary roof quotes in London.

What the patch says about us
Homeowners from Cranford to Hayes on how their jobs actually went.
"Woke up to tiles all over the front garden and not a breath of wind - couldn't work it out. They came the same morning, made it safe, and were the ones who told us it looked like vortex damage from the planes and that Heathrow has a scheme for exactly this. Helped us photograph everything properly for the claim. Could easily have just charged us for a repair and said nothing. That honesty is why I'm writing this."
"Our loft conversion started leaking around the dormer two winters after the conversion company vanished. Two roofers quoted big money to strip the whole dormer roof. These guys traced it to one badly-lapped flashing on the cheek, showed me the photo, fixed it in half a day. It's been through every storm since bone dry. The difference was they looked before they priced."
"Called them expecting to be told the roof needed doing - the house is 1936 and the ridge had been dropping mortar crumbs for a while. Survey verdict: re-bed the ridge, replace five tiles, and the rest is good for years yet. They even marked two tiles to keep an eye on. Quote was a fifth of what I'd braced for. When the roof does eventually need doing, they've earned that job."
"Water started coming through the back bedroom ceiling at 7am on a Sunday. Rang around - one lot quoted a £180 call-out before they'd even start. This firm answered, talked me through switching off the lights circuit and where to put the buckets, and was here by half nine. No weekend premium, made it dry, came back Tuesday and did the proper repair for a very fair price. Kept every promise they made on the phone."
"Had the fascias, soffits and gutters done on our terrace. What sold me was the survey - they pushed a screwdriver into the old boards to show me which were actually rotten and which were fine, then quoted to replace only what needed it. Other quotes were for capping over the lot, which they explained the problem with. Work was neat, gutters run properly for the first time in years, and the guarantee arrived as a proper document."

How To Choose A Roofer In Hounslow Without Getting Burned
A practical hiring guide for west London homeowners - the checks that expose a bad roofer in minutes, and the paperwork a good one produces without being asked.
What does a roof repair cost in Hounslow?
Usually less than the dread suggests. Single tiles and gutter fixes live in the low hundreds; flashings, ridges and chimney work climb with the scaffold they need; and five-figure conversations are reserved for roofs that are truly finished. Our cost guide publishes honest bands for every job type, so any quote you receive - from anyone - has something real to stand against.
Open the cost guideQuestions west London asks us
Which parts of west London do you cover?
Hounslow and everything around it: Heston, Cranford, Osterley and Lampton on the doorstep; Isleworth, Brentford and Feltham minutes away; Twickenham, Whitton and Richmond across the A316; Ealing and Hanwell to the north; Hayes, and out west to Uxbridge. Our base is on Southall Lane in TW5, so most of that list is inside a fifteen minute drive.
What happens on the free survey?
A real inspection, not a glance from the pavement: the roof from ladder height, the loft from inside where the evidence lives, and photographs of anything worth discussing. You get a plain-English verdict on the day and a fixed written quote if work is needed. No charge, no obligation - and when the honest answer is that nothing needs doing, that's the answer you get.
Is it true planes can damage roofs around Hounslow?
Yes - it's the most local roofing fact we have. Aircraft landing on Heathrow's westerly runways descend directly over this area, and occasionally a wake vortex - spinning air trailing the aircraft - reaches a roof hard enough to dislodge tiles, typically on a calm day. Heathrow acknowledges it and runs a Vortex Protection Scheme that repairs verified strikes free of charge, with blanket zones extending roughly 4km from the runway ends over Cranford, Heston and much of Hounslow. If your tiles moved without weather, mention it when you ring - it changes whose bill it should be.
Do I need planning permission for roof repairs in Hounslow?
For like-for-like repairs, no - on most houses it's permitted development. The care points locally: the borough has 28 conservation areas, including Old Isleworth, Spring Grove and The Butts in Brentford, where visible materials matter, and Bedford Park carries an Article 4 direction with tighter control. Cross into a neighbouring borough and the authority changes with it - Richmond upon Thames, Ealing and Hillingdon each run their own rules. We tell you exactly what applies to your address before work is priced.
How fast can you get to an urgent leak?
Same day is the aim for water actively coming in, and from TW5 most of the patch is a short run - Heston, Hounslow, Isleworth and Feltham often within the hour at quiet times. After a major storm, jobs triage behind active leaks and anything hanging over a footpath, which is the queue you'd want if it were your house. Either way you get an honest ETA on the phone, not a promise designed to win the booking.
What exactly does your guarantee cover?
Workmanship, for ten years, as a written document handed over at completion. If water gets in through work we carried out, we return and fix it at no cost - that's the whole clause, no wriggle room. Materials additionally carry their manufacturers' warranties, which differ by product, so your paperwork states the specific cover on your job rather than a vague site-wide claim.
The towns on our patch
Each has its own page, because each has its own housing, its own council and its own roofing habits - and pretending Richmond and Feltham need the same advice would be the first lie of the job.
