Melksham's roofs, from church to estate

Old market town buildings with chimney stacks — The old town by St Michael's and the Avon

Melksham grew around its parish church, St Michael and All Angels, a Grade II* listed building with twelfth-century origins and a restoration by T.H. Wyatt in 1845. A Friday market and a Michaelmas Fair were granted in 1219, and the main river bridge is first mentioned in 1415. That depth of history shows in the streets nearby, where older buildings have steep roofs, party walls, chimneys and parapets that all depend on careful flashing. The town has a conservation area, so put any plan to alter the appearance of a roof to Wiltshire Council first, and remember that listed buildings need consent for work touching their character. Behind the main streets, lanes of terraced and semi-detached houses add Victorian and Edwardian chimneys, bay windows with small lead-covered roofs, and rear outriggers whose valleys collect leaves.

Three-storey terraced houses with party walls — The Spa crescent and Georgian-era buildings

In 1815 the Melksham Spa Company built a crescent of three-storey lodging houses and a pump room at The Spa, which now lies in Melksham Without parish. Tall terraced buildings bring a different set of roof troubles from a cottage: long party walls, parapet gutters, abutments to keep watertight, valleys between ranges and chimney stacks shared with neighbours. Reaching them can mean scaffold or a tower. Work on a shared chimney or wall can also bring a party wall notice into play, so it pays to talk to the next house before anyone climbs a ladder.

Tiled semi-detached houses on a modern estate — Estates and twentieth-century growth

Melksham's population rose from about 14,204 in 2001 to 18,113 in 2021, and the town spread through the twentieth century with the Avon Rubber works and later estates. The result is a large stock of tiled semis, bungalows, terraces and newer homes, with garages, porches, extensions and flat-roofed additions attached. Their faults are those of houses of that age: ridges whose bedding has failed, valleys with worn lining, split felt and concrete-tiled slopes where moss holds water. Caught early these are usually modest repairs, and every roof is surveyed on what it is made of before anything is proposed.

Melksham roof questions

Is my Melksham street inside the town's conservation area?

The town has one, but its edges need checking street by street. Wiltshire Council can confirm your address before any roof work is planned.

How is a tall Spa terrace roof reached safely?

With scaffold or a tower, planned before anything else, because access can move the price as much as the repair itself does.

Who handles a Melksham re-roof that needs building control?

Wiltshire Council's building control team, or a registered building control approver, deals with notifiable work, and we file the notification ourselves.

What roofs surround Melksham's parish church?

The short answer

The streets around St Michael and All Angels hold Melksham's oldest buildings. The church is Grade II* listed, with twelfth-century origins and a restoration by T.H. Wyatt in 1845. Nearby houses have steep roofs, chimneys and party walls, so flashings and junctions are where most faults begin.

The town sits on level, fertile ground with some alluvial soil, in the wide Bristol Avon valley. An early settlement grew round the present parish church, and the market and fair granted in 1219 fixed the town's role as a centre for the villages around it. The roofs nearest the church have the longest history.

Why do junctions fail before slopes do?

Older buildings in a market town sit hard against each other. At the point where one roof abuts another, or climbs a higher wall, a flashing carries the join. Lead lasts a very long time when correctly fitted, but it fatigues and cracks, and mortar fillets pull away. A wet patch on a ceiling beneath an old chimney is far more often a failed flashing than a failed covering, and renewing the flashing is a smaller job than re-covering.

What does a chimney in an old terrace need?

Several parts: the stack itself, the pots, the flaunching (the sloping mortar crown that seats the pots), the lead collar around its base and the pointing in the brickwork. Any one can fail alone, so a leak does not always mean a rebuild. Sometimes the stack is shared with a neighbour, which can make a party wall notice relevant, so we ask early who owns what. Our chimney repairs page covers the work stage by stage.

Does consent apply near the church?

St Michael's is an Anglican church still in worship, so its roof work runs through the faculty system under the ecclesiastical exemption, not through the council. Houses, shops and offices nearby are ordinary buildings unless listed in their own right. For a listed one, listed building consent is the test. Wiltshire Council can tell you which category your address is in.

How do Melksham's flat roofs behave over shops and garages?

The answer

Flat roofs on extensions, garages and shop backs tend to fail at joints, upstands and outlets well before the open middle of the roof. A modern membrane such as EPDM or GRP is laid to a fall that finishes at no less than 1:80. Many failures are local, so a targeted repair is often enough.

A market town accumulates flat roofs: shop extensions, rear additions to terraces, garages, porches and the single-storey blocks behind older buildings. Melksham has plenty, and they work hard for little attention.

Why do flat roofs leak at the edges?

Because the edges are where the details are. Upstands against walls, drips over the fascia, outlets and rooflight kerbs each have to be waterproofed in their own right. Felt splits along joints, sealant dries out and a blocked outlet leaves water standing against a seam. A roof designed to a fall of 1:40, to achieve a finished minimum of 1:80, drains better than a nominally level one, because ponding is what shortens the life of any covering.

Which covering suits which roof?

EPDM is a synthetic rubber membrane, usually laid in a single sheet with few joints. GRP is a fibreglass resin finish laid over a deck, rigid and jointless. Torch-on felt is bitumen fused to the deck in layers, and lead suits small details. Typical lifespans from third-party guides are 20 to 30 years or more for EPDM, 25 to 40 for GRP and 10 to 20 for felt, depending on workmanship and care.

Is repairing a flat roof worth it?

When the fault is a failed joint or a split in an otherwise sound covering, yes. When the deck has rotted, or the sheet is breaking down from edge to edge, replacement is the better buy. You are told which applies, with photographs as evidence, and the reasoning is written down so you can weigh it at leisure. Our flat roofing page sets out the options in more detail.

Where a replacement affects more of the roof than the thresholds allow, Building Regulations can apply. Approved Document L lists replacing a flat roof's waterproof membrane as a renovation of that part of the building, so a better level of roof insulation can be required while the work is under way. It is worth knowing before the quote is accepted, because it affects the scope of the job and the thickness of the build-up.

MythA flat roof should have no slope at all.

FactWater has to run somewhere, so a flat roof is built with a gentle fall to its outlet; a truly level one pools and ages faster.

The short answer

Expect a survey and photographs of your roof first, with a written quote afterwards. Notifiable work is passed to Wiltshire Council's building control team or a registered building control approver, which we arrange. VAT and scaffolding both change a total, so ask whether they are included.

Melksham is a town with no shortage of builders, but a good roof job begins the same way anywhere: with a plain description of the fault and a quote you can follow.

What goes into the quote?

A single total price, in writing, after the survey. Access, the choice of covering, the area of roof and whatever the survey turns up are what move it. If you are weighing other quotes, put the same VAT and scaffolding question to every firm. National guides publish ranges, such as MyBuilder's roof repair guide at £150 to £1,500 (updated 21 August 2026), but those are typical UK figures, not our price. The survey is what fixes the figure for your roof.

When does building control apply?

The Planning Portal says re-covering that touches under 25 per cent of the total building envelope and under 50 per cent of the roof is not normally an application matter, and for most Melksham houses a like-for-like re-cover stays well under both. Exceed either figure, or choose a covering 15 per cent or more heavier, and approval may be required. In Melksham the route is Wiltshire Council's building control team or a registered building control approver.

Does the conservation area matter?

It can. Mending a roof with matching stuff seldom needs an application, though a different covering, new openings or reworked chimneys might. The planning team at Wiltshire Council can advise on your own address, and a clear description of the job from us makes their answer quicker. Our roof repairs page explains how a fault is judged before a fix is chosen.

At the end you get a tidy site, the rubbish gone and a ten-year guarantee covering our workmanship, in writing, with any building control paperwork to keep alongside it.

Match the repair to the fault, and match the quote to the survey.

Questions from the Avon valley

Why do the roofs near Melksham's market place look so mixed?

The town has been rebuilt and extended across the centuries. It was granted a market and fair in 1219, saw a Georgian spa development in 1815 and grew again through the twentieth century with the Avon Rubber works and later estates. Each period left different coverings, so no one repair method suits every street.

Can you fix a chimney stack shared with the house next door?

Yes. A shared stack calls for a conversation with the neighbour first, because work on a party wall can need a notice. Removing the breast inside is a different matter, because that always needs Building Regulations approval, and chimneys removed from a party wall bring the Party Wall Act into play. A repair is simpler, and we agree access and timing with both households.

Is a flat roof over a Melksham shop or garage worth repairing?

Trouble confined to one open seam, a lifted edge strip or a choked outlet is usually worth mending. A deck that has gone soft, or a membrane worn from edge to edge, points to a new covering instead. Photographs of your own roof lay out the evidence before you decide, and shop or garage owners can usually keep trading during the work.

Do old Melksham ridges rely on mortar bedding alone?

Many do, since a mortar bed was the habit for generations. BS 5534:2014 added a second layer of security: the ridge is held down mechanically too, and for an older tiled roof in town that is a sensible upgrade to ask about.
