- Swindon: 01793 230 678
When your roof develops an urgent problem — a sudden leak, storm damage, loose ridge tiles, or a failed flat roof covering — GWR Roofing Ltd are available 24/7 for emergency call-outs across all of Swindon. We prioritise urgent jobs and aim to attend the same day where possible. Emergency call-outs are common in Swindon after periods of strong wind, which frequently dislodge the ridge tiles and verge mortar on the concrete tile roofs of the town’s post-war estates — particularly across Penhill, Walcot, Park South and Covingham. These tiles can fall and cause immediate safety risks as well as further water ingress. Call 01793 230 678 or 0800 191 0841 to speak to us directly about an emergency.
Emergency Leak Repairs
Roof leaks rarely develop at a convenient time. Whether the cause is a broken slate, failed flat roof covering, cracked lead flashing or a dislodged tile, we respond quickly to emergency leak call-outs across Swindon. For temporary protection while a permanent repair is arranged, we can apply weatherproof coverings to prevent further water ingress. Call 01793 230 678 — we are available 24/7.
Storm Damage Repairs
Swindon sits in an exposed position on the Vale of White Horse and can receive strong south-westerly winds that dislodge ridge tiles, lift verge mortar and tear at flat roof coverings. After storm events we receive a high volume of calls from across the town's estates. We attend, make safe, and carry out a full repair — not just a temporary patch. All storm damage repairs are quoted in writing before work begins.
Tile & Slate Roof Repairs
The two roof types most commonly in need of tile and slate repair in Swindon are the Victorian and Edwardian natural slate roofs in Old Town (where slates slip when the original iron nail fixings corrode) and the concrete interlocking tile roofs on the post-war estates across north and east Swindon (where ridge and verge mortar failures are the most common presenting issue). We match materials like-for-like — reclaimed Welsh slate for older roofs, and matching concrete tile profiles for estate properties — to ensure a neat finish and correct weatherproofing.
New Roofs/Re-Roofing Swindon
Expert New Roof Installations and Re-Roofing in Swindon
New roofs and full re-roofs in Swindon typically fall into two categories. The first is the post-war concrete tile roof on properties across Swindon’s larger estates — many of these are now 50 to 60 years old and have reached the point where cumulative repairs no longer make financial sense. The concrete tiles themselves often remain structurally sound but the battens, felt underlay and ridge and verge mortar system are at end of life. A full re-roof — stripping to the rafters, installing new breathable membrane, new treated battens and a new tile system with dry-fix ridge and verge — is the correct long-term solution and is more cost-effective over a 10-year period than continued patchwork. The second is the Victorian and Edwardian slate roof in Old Town. When roof timbers are sound, these can be re-slated in reclaimed Welsh slate to maintain original character and avoid planning complications in conservation areas.
We supply and install Marley, Redland and Sandtoft tile systems as well as natural and fibre cement slate. All new roofs are quoted as a fixed price inclusive of scaffold and waste removal and carry our company guarantee.
Pitched Roof Installations
For pitched roof replacements in Swindon we work with both concrete and clay interlocking tile and natural or fibre cement slate. On the post-war estates concrete tile (Marley Anglia or similar) is the standard match; in Old Town and conservation-adjacent streets we recommend reclaimed Welsh slate or a suitable fibre cement alternative where natural slate is not available. All pitched roofs include new breathable felt underlay, treated batten and dry-fix ridge and verge as standard.
Flat Roof Installations
The garages, rear extensions and single-storey side returns on Swindon's post-war estates were almost universally built with felt flat roofs that are now long past their design life. We re-cover these in GRP fibreglass (25-year guarantee, no maintenance), EPDM rubber (better for larger spans), or high-performance torch-on felt where budget is the primary constraint. We advise honestly on which system is correct for each specific roof.
Roof Replacement Services
When repairs are no longer cost-effective we provide a full roof strip and replacement. We inspect the roof structure before quoting — if timbers are damaged we include remedial joinery in the price. We never quote a replacement without first explaining clearly why repair is not the better option for your specific situation.
Flat Roofing Swindon
Durable and Efficient Flat Roofing Services in Swindon
Flat roofs are extremely common across Swindon’s housing stock. The majority of garages, rear kitchen extensions and single-storey side returns on the town’s post-war estates were built with traditional felt flat roofs that are now well beyond their intended lifespan. A felt flat roof more than 15–20 years old is typically at the point where full replacement is more cost-effective than ongoing patching — the felt becomes brittle, splits at laps and around upstands, and water finds its way in at multiple points simultaneously.
We install GRP fibreglass (seamless, 25-year guarantee, no maintenance — our most popular choice for Swindon garages and extensions), EPDM rubber (better suited to larger or irregular-shaped roofs) and high-performance torch-on felt. We give you an honest recommendation on which system is right for your roof, explain cost and lifespan differences clearly, and quote a fixed price before starting. All flat roof work includes correct drainage falls where possible.
EPDM Flat Roofs
EPDM rubber is our recommended system for larger flat roofs — typically over 30–40m² — where a single seamless GRP installation would be impractical. It is highly flexible, UV-resistant, and carries a long manufacturer warranty. We use it frequently on commercial flat roofs and larger domestic extensions across Swindon.
GRP Flat Roofs
GRP fibreglass is the most popular flat roofing system we install on domestic properties in Swindon — particularly on garage roofs and kitchen extensions on the town's post-war estates. It is seamless, extremely durable, and comes with a 25-year manufacturer guarantee. Once installed it requires no ongoing maintenance and will not crack, split or lift at laps as felt does over time.
Flat Roof Repairs
Where a flat roof is structurally sound but has isolated failures — a split lap, a failed upstand, or a blister — we carry out targeted repairs rather than recommend a full replacement. We will always give you an honest assessment of whether repair or replacement is the more cost-effective option for your specific situation. For roofs approaching end of life, we will say so clearly.
Lead Roofing & Lead Work Swindon
Professional Leadwork Services in Swindon
Lead work is an essential part of roofing on Swindon’s older properties. The Victorian and Edwardian houses in Old Town and the streets around the town centre almost all have lead flashing at chimney bases, valley gutters and dormer junctions. When lead flashing fails or lifts — often caused by failed mortar fixings or thermal movement pulling the lead away from the abutment — water runs directly into the roof structure and typically presents as a damp patch on an upstairs ceiling weeks or months later. We carry out lead flashing repairs and replacements, step and soaker flashings, valley gutter lead lining, and lead-covered bay roof installations across Swindon. All lead work is carried out to Lead Sheet Association standards.
Lead Roof Installations
Lead is the traditional material for bay window roofs, flat-roofed dormers and porches on Swindon's older properties. We install new lead roofs to the correct Code 4 or Code 5 specification with proper drips and welts to allow thermal movement. Correctly installed lead lasts 70–100 years with minimal maintenance.
Lead Flashing & Leadwork
Chimney flashing failure is one of the most common causes of roof leaks in Swindon's older housing stock. We repair and replace step flashings, back gutters and soakers at chimney abutments, dormer cheeks and roof-to-wall junctions. Where lead has been previously repaired with flash band or mastic as a temporary fix, we replace this with proper lead flashing to eliminate ongoing problems.
GWR Roofing Ltd has the skills and knowledge to give you long-lasting solutions, whether you require a new lead roof, repairs, or custom lead work for your property. Call us today for a free, no-obligation estimate and make sure your roof is safe with high-quality lead materials.
Slate & Tile Roofing Swindon
Enhance Your Home with Durable, Timeless Slate and Tile Roofs in Swindon
Swindon has two distinct slate and tile roofing contexts. In Old Town and the Victorian streets around the town centre, properties were built with natural Welsh slate — dark, thin, and distinctive. When these roofs need replacing, like-for-like reclaimed Welsh slate is the correct approach, particularly for properties in or adjacent to conservation areas. Modern fibre cement slate is a suitable alternative where natural slate budget is a constraint. On the large post-war estates across north and east Swindon — Penhill, Walcot, Park South, Pinehurst, Covingham — concrete interlocking tiles were the standard build material. These are robust tiles that typically outlast their mortar systems, meaning the tiles themselves are often still serviceable when the ridge, verge and valley mortar has long failed. We carry out full re-tiling, partial re-tiling and repair work across both contexts, and supply Marley, Redland and Sandtoft systems for new tile installations.
Why Choose Slate & Tile Roofing?
Natural slate is the most durable roofing material available — a correctly installed Welsh slate roof can last 100 years or more. For Old Town and Victorian Swindon properties this matters both aesthetically and from a planning perspective. Concrete interlocking tile is the correct choice for post-war estate properties and offers a strong, low-maintenance solution when installed with modern dry-fix systems. We advise on the most appropriate material for each specific property and provide samples to assist with colour and profile matching.
Chimney Repairs Swindon
Professional Chimney Repairs in Swindon – Ensuring Safety and Efficiency
Chimney repairs are among the most common jobs we carry out in Swindon, particularly on the Victorian and Edwardian properties in Old Town and the older residential streets close to the town centre. These properties have brick chimney stacks with lime mortar pointing that has softened, eroded and in many cases washed away over decades of Wiltshire weather. Failed pointing allows water into the brick and chimney structure, and in winter the freeze-thaw cycle causes spalling of the brickwork face. Repointing with the correct mortar — lime mortar for pre-1920s properties, never cement, which traps moisture and accelerates brick deterioration — is the correct repair. Lead flashing at the chimney base is the other common failure point on these properties: when flashing fails or lifts, water runs directly into the roof structure and typically presents as a damp patch on an upstairs ceiling weeks later.
Chimney Stack Repairs
Chimney stack repairs on Swindon's Victorian stock typically involve lime repointing of the stack, replacement of individual spalled or damaged bricks, and re-bedding of chimney pots in lime mortar. Where structural movement has caused cracking we also carry out full rebuilds of the stack above the roofline. All work is carried out from scaffold and all chimney pots are secured to prevent displacement in high winds.
Chimney Flashing Repairs
Lead flashing failure at the chimney base is a very common roof leak source on Swindon's older properties. The failure is often a combination of mortar chase failure and thermal movement pulling the lead away from the abutment. We cut fresh chases, re-dress the lead, and secure with lead wedges and fresh mortar. Where previous repairs have used flash band or mastic we replace these with proper lead flashings.
Chimney Crown & Cap Repairs or Replacements
Where chimneys are no longer in use we recommend capping to prevent water ingress and bird nesting — both common problems on Swindon properties with redundant chimney stacks. We install proprietary chimney caps or traditional lime mortar haunching. For active chimneys we can supply and fit replacement chimney pots and secure them correctly in fresh lime mortar.
Chimney Repointing
Chimney repointing is the most frequent chimney job we carry out in Swindon. The critical point is mortar specification: pre-1920s brick chimneys must be repointed in lime mortar, not cement. Cement is harder than the brick and forces moisture to migrate through the brick face rather than through the sacrificial mortar joint — the result is accelerated spalling. We always use the correct mix for the age and type of brick, and we will advise you if a previous repoint in cement mortar has caused brick damage that also needs addressing.
Fascias, Soffits & Guttering Swindon
UPVC Fascias, Soffits & Guttering — Swindon
Fascia, soffit and gutter replacement is one of the most common roofline jobs we carry out across Swindon. The original timber rooflines on the town’s post-war semi-detached and terraced properties are now typically well beyond serviceable life — timber has softened, paint has failed, and boards are often bowed, cracked or rotten at the ends where water has pooled in the gutter. Failed fascias expose rafter feet and wall plate to ongoing water ingress and are a common cause of roof structure deterioration that goes unnoticed until significant damage has occurred.
Overflowing or leaking gutters are also among the most common causes of damp patches on internal walls in Swindon properties — frequently misdiagnosed as rising damp when the actual cause is a leaking gutter joint or blocked downpipe. The uPVC gutter joints on post-war estate properties dry out, crack and fail after 20–30 years. Old Town and Victorian-era properties are more likely to have cast iron guttering, which lasts well when maintained but rusts through at joints when paint fails. We repair, repaint and replace cast iron systems as well as uPVC.

Fascia Installations & Replacements
We replace timber fascias, soffits and bargeboards with modern uPVC systems across Swindon — available in white, black, woodgrain and a range of other colours and profiles. uPVC requires no repainting, does not rot, and requires only occasional cleaning. All roofline replacement work includes correct soffit ventilation inserts where required.
Soffit Installations & Repairs
Soffit replacement on Swindon's post-war housing stock almost always accompanies fascia replacement. When original timber soffits are replaced with uPVC we fit ventilated soffit panels where the roof has no other ventilation path — this is a Building Regulations requirement and prevents moisture accumulation in the roof void that leads to condensation and timber decay.
Guttering Installations & Repairs
We carry out gutter repairs, gutter cleaning, gutter re-alignment and full gutter replacement across Swindon. For full replacements we install uPVC guttering in half-round, square and ogee profiles. We also carry out cast iron gutter repairs — common on Old Town properties — including joint re-sealing, rust treatment and repainting. Gutter cleaning is available as a standalone service and we recommend annual cleaning for properties under trees.
Professional Velux Window Installations in Swindon
Transform Your Space with Velux Roof Windows
Velux roof window installations are a popular addition to Swindon properties, particularly on the semi-detached houses across the town’s estates where loft conversions offer a practical way to add a bedroom without the cost of a full extension. Many of Swindon’s post-war semis have roof pitches that are suitable for habitable loft conversion with the addition of Velux windows, and we work alongside builders and loft conversion specialists across the town to supply and fit the window and flashing system correctly. We also replace failed or leaking existing Velux windows — the most common issue is a failed flashing kit on an older installation that allows water to track into the roof structure.
We supply and install genuine Velux roof windows across Swindon on all pitched roof types — tile and slate — in centre-pivot, top-hung and combination configurations. All installations include the correct tile or slate flashing kit for the specific roof profile. We also install flat roof Velux systems on extensions and outbuildings. Sun tunnels are available for rooms where a full window is not possible.

On Swindon's post-war estate properties the most common signs are ridge tiles that have shifted or fallen, verge mortar that is visibly cracked or missing, and water staining on upstairs ceilings — these all typically indicate mortar failure rather than the tiles themselves. On Victorian properties in Old Town, slipped slates and damp patches near chimney bases are the most common warning signs. If you are unsure, we offer free roof inspections across Swindon — call 01793 230 678 and we will assess the roof and give you an honest recommendation.
Yes — we carry full public liability insurance and employer's liability insurance. We are happy to provide evidence of our insurance cover before starting any job. All new roofs carry our company guarantee. We are a directly employed team — not a franchise or agency — so you deal with us from first call to final invoice.
The cost depends on the type and size of job. As a general guide for Swindon properties: a full re-roof on a three-bedroom semi-detached typically ranges from £4,500 to £8,000 including scaffold and waste removal. Ridge and verge repointing on a typical Swindon estate property is usually £400–£900 depending on the extent of failure. A GRP flat roof on a standard single garage is typically £900–£1,500. We provide free, fixed-price written quotes after inspecting the roof — the price quoted is the price charged, with no additions.
Yes — we offer 24/7 emergency roofing services across Swindon and the surrounding area. We prioritise emergency call-outs for storm damage, sudden leaks, fallen ridge tiles and any situation where the roof is unsafe or water is actively entering the property. Call 01793 230 678 or 0800 191 0841 at any time.
Most roof repairs we carry out in Swindon are completed within a single day. A full re-roof on a semi-detached property typically takes 2–4 days depending on size and complexity. We keep the work site tidy at the end of each day, remove all waste on completion, and communicate clearly with you throughout. For jobs requiring scaffold we arrange access scaffolding that causes minimal disruption to the front or side of the property.
