Roofers in St Margarets, TW1
Last reviewed 24 October 2026
Edwardian terraces, bay window roofs in lead, box gutters above the shops on Crown Road, and a conservation area with Article 4 Directions. Property Restoration Services London Ltd repairs and renews roofs across St Margarets, and we know which of those details decides how a job is done.
Which Street Are You On? What Each Part of St Margarets Needs
St Margarets was built mainly between the 1880s and the First World War, and the roof problem depends on the street. St Margarets Grove and Amyand Park Road have slate and clay tile, Crown Road has shop parade box gutters, Cambridge Park has hipped roofs and loft conversions, and the streets toward Marble Hill Park have lead bay roofs.
St Margarets grew up quickly once the station opened in October 1876 on the London and South Western Railway line from Waterloo. Much of the housing dates from the 1880s to the First World War, including the former Cambridge Park estate, redeveloped by the builder Henry Cresswell Foulkes after it was sold off in the 1890s. The result is a compact area with a lot of near identical houses, which is why small differences between streets matter.
St Margarets Grove and Amyand Park Road
Edwardian terraces and semi-detached villas in brick and stucco, with pitched slate or clay tile roofs and decorative ridge tiles.
We usually find: slipped slates, cracked ridge tiles and shared valley gutters that nobody has looked at in years.
Crown Road
A parade of independent shops with flats built into the same Edwardian terraces above.
We usually find: box gutters above the shopfronts blocked by leaves and moss, and rear flat roofs that need access arranged around trading hours.
Cambridge Park
Streets developed from the 1890s on the old Cambridge Park estate, with hipped roofs and many loft conversions.
We usually find: extra flashing junctions around dormers and rooflights that were never detailed as carefully as the original roof.
St Margarets Road toward Marble Hill Park
Some of the oldest roofs in the area, larger detached and semi-detached villas, and listed landmarks such as the Kilmorey Mausoleum.
We usually find: small lead flat roofs over bay windows, failing at upstands and joints.
Is the Stain on Your Bay Window Ceiling Coming From the Lead Roof Above?
Yes, often. Small flat roofs over Edwardian bay windows are usually covered in sheet lead, and lead tends to fail at joints and upstands. A stain on the ceiling below the bay is a common first sign, and the repair needs to be made in lead, not in felt or bitumen.
On the larger Edwardian villas toward Marble Hill Park and the river, the bay windows at ground and first floor level often carry a small flat roof covered in sheet lead. When lead fails it usually fails at a joint or an upstand, not across the whole sheet. A felt or bitumen patch over lead does not hold because the two materials move differently with temperature. The repair needs to be made in lead.
- We look from above and below. A stain inside tells us the area; the roof tells us the cause.
- We check the upstands and the flashing where the bay meets the wall behind it.
- We repair or renew only the failed section where the rest is sound, and say so if it is not.
- We photograph the finished work so you can see what was done.

Slate, Clay Tile or Lead: What Goes Where on a St Margarets Roof?
Natural slate suits the main pitched roofs on older terraces, clay tile suits hipped roofs and decorative ridges, sheet lead is used for bay roofs, valleys and flashings, and a flat roof membrane covers rear extensions and dormers. The table shows each covering's usual fault and the repair we make.
| Covering | Where you see it here | The usual fault | What a good repair looks like |
|---|---|---|---|
| Natural slate | Main pitched roofs on older terraces and villas | Fixings age and individual slates slip | Matching slates, individually replaced, not a sheet of sealant over the gap |
| Clay tile | Hipped roofs, roofs with decorative ridge tiles | Cracked tiles and failed ridge bedding | Same colour and profile, ridge re-bedded or mechanically fixed |
| Sheet lead | Bay window roofs, valleys, flashings, chimney trays | Cracks at joints and upstands | Lead repair or renewal of the failed section, with correct laps |
| Flat roof membrane | Rear extensions and loft dormers | Splits, ponding, failed edge trims | Renewal in a suitable membrane, tied into the old roof with proper flashing |
What Does an Article 4 Direction Mean for Your St Margarets Roof?
An Article 4 Direction removes some permitted development rights, so a different roof covering, front rooflights or chimney changes may need planning permission. Replacing tiles with the same material is normally a repair. Check Richmond's Article 4 register for your address before work begins.
An Article 4 Direction takes away some of the rights homeowners normally have to alter a house without applying for planning permission. In the St Margarets Estate conservation area, Richmond Council has applied Article 4 Directions that cover roof alterations facing a road or open space, and alterations to chimneys wherever they are. In practice, replacing slates or tiles with the same material is a repair, while changing the covering, adding rooflights to the front slope or altering a chimney may need permission.
The details depend on your address and the direction's current status, so check Richmond's Article 4 register before work begins. We will tell you at the inspection if anything we propose looks likely to need consent.

What Do St Margarets Homeowners Ask About Roofing?
Why does lead on a bay window roof fail in St Margarets?
Lead expands and contracts with temperature, and over many years the joints and upstands crack or lift. Old patches in felt or bitumen make it worse because they move differently from lead. On the Edwardian villas toward Marble Hill Park the bay roofs are small and easy to overlook until a stain appears on the ceiling below. A proper repair is made in lead, with correct laps and upstands.
Do I need permission to replace roof tiles in the St Margarets conservation area?
Replacing tiles with the same colour, profile and fixing is normally a repair, but check first. Article 4 Directions apply to parts of the St Margarets Estate conservation area, covering roof alterations facing a road or open space and alterations to chimneys. Changing to a different covering or adding rooflights to a front slope may need permission. Check Richmond's Article 4 register for your address.
What causes leaks above the shops on Crown Road?
Most often it is a box gutter. Sitting between a parapet and the roof, a box gutter collects water from a large area and drains through a small outlet that leaves and moss block easily. When it backs up, water finds its way into the flat or shop below. We clear, repair or renew the gutter and check the lead lining and outlets.
Can you match the slate on my St Margarets Grove house?
In most cases yes. We match size, thickness, colour and fixing pattern as closely as possible, and where original slates are sound we reuse them. If an exact match is not available, we explain the nearest alternative and show you samples so you can decide before work starts.
Do you repair hipped roofs and ridge tiles around Cambridge Park?
Yes. Hipped roofs on the old Cambridge Park estate often have cracked ridge and hip bedding, and loft conversions add flashing junctions that fail over time. We re-bed or mechanically fix ridge and hip tiles, replace broken tiles and reseal dormer and rooflight junctions.
How do you arrange access on a terrace with shared walls?
We plan access with you at the inspection. On a terrace, scaffold may be needed on the front or rear elevation, and neighbours sometimes need advance notice, especially if scaffold or ladders cross a boundary. We tell you what is needed before booking and discuss how to inform neighbours.
Can you inspect a St Margarets roof before I buy or sell?
Yes. We give a written condition summary covering coverings, chimneys, lead, valleys, gutters and flat roof sections, with photographs where safe. It helps a buyer to understand repairs ahead of an offer, and it helps a seller to deal with problems before a survey picks them up.
