flat roof repair Hounslow starts with a Southall crew of J.J Roofing & Construction Ltd on TW3 and TW4 coverings: EPDM rubber, torch-on felt and GRP fibreglass, after a site visit rather than a copied patch price, Monday to Saturday, 8am to 8pm.
After inspection we quote that membrane. We confirm workmanship in writing when the job is finished. Hours are Monday to Saturday, 8am to 8pm. However, Sunday is by appointment only. In fact, this is not a pitched-replacement page.

J.J Roofing & Construction Ltd treats Hounslow flat roofs as a membrane job: garage lids, rear extensions, 1960s and 1970s additions, and low-pitch covers that pond after rain. Furthermore, the crew loads from Southall, not from a Hounslow shopfront. Hours stay Monday to Saturday, 8am to 8pm. Phone 07448 055535.
- EPDM rubber: seams, punctures, trims and failed adhesive at upstands.
- Felt: splits, blisters, open laps and tired mineral caps on older torch-on.
- GRP fibreglass: cracks at details, failed trims and edge splits.
- Drainage: outlets, upstands and falls, because a patch on a ponding deck rarely lasts.
This URL owns flat roof repair in Hounslow. In contrast, pitched leaks across the western boroughs sit on roof repairs in West London. A Berkshire re-cover sits on roof replacement Windsor. Wider roofing sits on roofing services, and towns we reach are listed on our areas.

What this flat roof repair Hounslow page covers
Hounslow town (TW3) and Heston / Lampton (TW4) still carry a lot of rear extensions and garage roofs from the 1960s onwards. Historically, those decks were often felt. As a result, many are now due for renewal. Many have been overlaid, then overlaid again, until the falls have gone. Water sits, seams open, and the ceiling in the extension stains first. In short, that is the job this page is for. It is not a pitched strip in Windsor, and it is not a West London tile leak.
We do not publish a Hounslow pound-per-square-metre for EPDM, felt or GRP, because a 12 m² garage lid is not a 40 m² extension with six penetrations. Pricing follows that visit. Email jjroofingandconstructionltd@gmail.com or call 07448 055535.
Pick your job
Open a membrane type. Inside you get the defect, the pictures to send, and the number for the Southall desk.
EPDM rubber
EPDM rubber seams and punctures
Because EPDM fails at seams, trims and penetrations more often than in the middle of a clean sheet, we clean, prime and detail the leak rather than painting over wet rubber. If the sheet has shrunk off the upstand, however, a local patch is not always enough, and we will say so on the visit.
Send us: photos of the sheet, the upstand, and any standing water. Also tell us the age of the covering if you know it.
For an EPDM inspection, Monday to Saturday, 8am to 8pm, use 07448 055535.
Felt splits and blisters
Felt splits, blisters and laps
For example, torch-on felt still covers a lot of Hounslow extensions. Laps open, blisters hold water, and mineral caps weather off. A local repair can close a split if the deck and falls still work. Nevertheless, repeated blistering across the whole lid usually means a recover, not another patch.
Send us: photos after rain, a shot of the outlet, and whether the leak tracks a wall or a light.
Ask for a felt visit on 07448 055535.
GRP fibreglass
GRP fibreglass cracks and trims
Meanwhile, GRP is a hard, walkable finish that still cracks at trims, drips and changes of direction. Weather windows matter because laminate needs a dry deck. Therefore we will not rush a GRP detail in standing water just to tick a same-day box.
Send us: close-ups of the crack, the trim, and whether the roof is used as a terrace.
Call the Southall desk on 07448 055535.
Ponding, outlets and upstands
Ponding, outlets and upstands
In particular, a flat roof still needs a fall. Ponding after rain is the most common reason a Hounslow patch fails a year later. As a result, we check outlets, upstands, and whether the deck has sagged. Drainage is part of the repair, not a separate upsell.
Send us: a photo taken a few hours after rain, plus the position of the indoor stain.
Book the drainage look on 07448 055535.
Overlay versus a full strip
Overlay versus a full strip
Although an overlay on sound deck and insulation can be the right call, overlay on rotten boarding or a deck with no fall is a delay, not a repair. Consequently we open up enough to see the timber before we sell either route. Insulation upgrades, when required, sit under Building Regulations and Hounslow Building Control recovering rules.
Send us: any previous invoices for the covering, and whether a loft or extension drawing exists.
We book a recover survey on 07448 055535.

Flat roof repair Hounslow: TW3 and TW4 stock in wet winters
Hounslow gets long wet spells, then sudden heavy rain that sits on a low-pitch lid. Felt laps that looked sound in July open in November. EPDM adhesive at a cold upstand is a different job from a summer seam. GRP needs a dry window. Therefore we will not sell a same-day fibreglass laminate in standing water, and we will not claim 24/7 night work that the hours page does not support.
Access on TW3 terraces is often a narrow side return. Garage roofs on TW4 estates are simpler to reach and still leak at the same details. Working at height on a two-storey extension follows HSE work at height and the wider HSE construction pages. Industry practice sits with the NFRC.
Building control, insulation and access
A small patch on an existing covering is usually a repair. Recovering a whole lid, changing insulation, or altering the roof on a house in a conservation area can be a Building Control or planning question. Hounslow’s conservation-area notes flag ridge and roof-size changes; they are less often the issue on a rear flat, but flats and converted houses lose many permitted-development rights. The Planning Portal roof pages remain the national starting point. We pause for those papers when the job is more than a leak seal.
If the leak sits under a loft conversion or a new rear addition, pair this page with loft conversions or house extensions. The membrane still has to drain.

TW3 — Hounslow town and Lampton
Specifically, TW3 is dense terrace and later infill with narrow returns and a lot of rear extension lids. Access and neighbour boundaries decide whether a tower is enough for the membrane job.
TW4 — Heston and Cranford, plus nearby Isleworth and Osterley
Likewise, TW4 estates add garage roofs and wider side access. Isleworth and Osterley sit on the same run; give the postcode so the visit can be confirmed. Dedicated pitched work in the wider west sits on the West London repair hub.
Night-and-day attendance is not a claim we make. Reach us 8am–8pm Monday–Saturday; Sunday only when an appointment is set. Crews still start in Southall.

Frequently asked questions
How much does flat roof repair Hounslow cost? No EPDM, felt or GRP square-metre rate is listed. You get a written figure after we have seen the deck, the falls and the leak.
EPDM, felt or GRP — which is right? It depends on the existing covering, the deck, foot traffic and the weather window. We recommend on inspection rather than from a generic lifespan table.
Do you offer 24/7 call-outs? No. We are contactable Monday to Saturday, 8am to 8pm, and on Sunday by appointment, for leaks during those hours.
Can you overlay old felt? Sometimes, if the deck and falls are sound. Overlay on rotten boarding is a delay. We open up enough to see before we sell that route.
Do you cover TW3 and TW4? Yes. Hounslow town, Lampton, Heston and nearby Isleworth, Osterley and Cranford sit on this Southall run.
