Experienced With Hounslow Homes

Roof Repairs in Hounslow: What's Included
From a single slipped tile to a full re-roof, our professional roofing team covers every job across TW3 and TW4.
Trusted Roof Repairs
Whether it is slipped tiles, cracked ridge pointing, failing lead valleys and broken ridge caps. Most repairs in Hounslow are completed within 24 to 48 hours of your call.
Emergency Roof Repair
Whether it is storm damage, sudden leaks, or a fallen chimney stack — we make the roof safe and weatherproof quickly, then return to finish the full repair.
Flat Roof Repair & Replacement
As you might expect, Many Hounslow homes have flat-roofed rear extensions, garages and dormer loft conversions. In particular, we fit GRP fibreglass (seamless and hard-wearing), EPDM rubber (good for bay roofs and dormers) and torch-on felt for larger, budget-conscious areas.
New Roof Installation
Essentially, full strip-and-reroof to NFRC industry standards, in clay, concrete, natural slate or synthetic slate. Importantly, every new roof includes a written specification and a signed 10-year guarantee.
Chimney Repairs
Understandably, Many of Hounslow's older and interwar homes still have their original chimney stacks, and these need regular attention — repointing, flaunching repair, Lead Sheet Association standard soaker replacement, pot removal and full stack rebuilds.
Guttering, Fascias & Soffits
This includes UPVC, aluminium and cast iron gutter replacement, downpipe re-routing and fascia renewal. In most cases, guttering jobs across TW3 and TW4 are finished in a single day.
Soffit & Fascia Renewal
Fascia and soffit board replacement on older Hounslow properties, including safe removal of asbestos-containing boards in line with HSE asbestos guidance, carried out through licensed waste carriers.

Experienced Roof Repairs for Every Hounslow Property Type
Hounslow's homes range from Victorian terraces near the town centre to 1930s semis in Lampton, Hounslow West, Heston and Cranford, many with dormer loft conversions and flat-roofed rear extensions, so we approach each roof differently.
Hounslow Housing Stock
Most Hounslow roof repairs we see fall into three groups. First, Victorian terraces near the town centre, with slate roofs, lead valleys and chimney stacks that are now well over 100 years old. Second, the 1920s and 1930s semis across Lampton, Hounslow West, Heston and Cranford, with hipped tile roofs where slipped tiles, rusted nails and worn ridge mortar are common. Third, the dormer loft conversions and flat-roofed rear extensions added to both, where leaks often start at the joins with the original roof. Large parts of TW3, TW4 and TW5 also sit under the Heathrow approach path. If you think aircraft turbulence has dislodged your tiles, report it to Heathrow first, as the airport runs a scheme for this type of damage.
Fast Local Response
Based 15 to 20 minutes from Hounslow, we can usually reach an emergency within 2 to 4 hours, any day of the week.
What This Means For Your Roof
In practice, most of our Hounslow call-outs are leaks where a dormer or extension meets the main roof, slipped or broken tiles on interwar roofs, and worn lead flashing around chimneys. We trace each leak to its source rather than sealing over the damp patch. If your home is listed or in a conservation area, we check with the London Borough of Hounslow before changing roof materials.

Yes. We repair slate roofs, lead valleys and chimneys on the Victorian terraces near Hounslow town centre, and the hipped tile roofs on the 1930s semis in Lampton, Hounslow West, Heston and Cranford. We match the existing tiles or slate wherever possible.
On average, a well-installed pitched roof lasts 40 to 60 years, while flat roof systems such as GRP fibreglass or EPDM rubber last 20 to 30 years. Every new roof carries a signed 10-year workmanship guarantee, plus manufacturer product warranties.

In general, for extensions, GRP fibreglass is usually the strongest option — seamless, low maintenance, with a 25-year warranty. Meanwhile, EPDM rubber suits larger flat areas well, while torch-on felt is the most affordable choice for budget-sensitive jobs. Then, we recommend the right system after a free site visit.
Yes. Some older Hounslow properties still have original cast iron guttering. We repair, re-seal, re-hang or fully replace it, and where a conservation area requires the period look, we can fit cast iron-effect aluminium instead.
Yes. We replace full guttering runs, fascias, soffits and downpipes across TW3 and TW4, in UPVC, aluminium or cast iron depending on the property. Typically, most jobs are completed in a single day.
To summarise, signs pointing to a full re-roof include several sections of slipped or broken tiles, widespread moss under the bedding, failing underlay visible from the loft, leaks that return after previous repairs, or a roof over 50 years old with no replacement history. Initially, we inspect for free first and only recommend a re-roof where repairs genuinely won't be enough.
