Roofers in Midsomer Norton

Midsomer Norton lies 10.4 road miles south-west of Bath, in the valleys of the River Somer and the Wellow Brook. Shops and flats around the High Street, older houses near the Island and the large roofs of its listed churches each need their own approach, and our roofers repair or replace all three across the town.

Local roofs

A town in two Mendip valleys

Midsomer Norton occupies two valleys on the edge of the Mendip Hills. The River Somer runs through one and the Wellow Brook through the other, and the two valleys merge west of Radstock. That geography shapes the town. Streets climb the valley sides, buildings step down the slope, and for much of its history the water in the valley floor has been a matter for the town itself: a flood alleviation tunnel completed in 1977 now carries surplus water from the River Somer beneath the High Street.

The centre has buildings from several periods. Island House, in The Island, was built in the early eighteenth century, and the Town Hall followed in 1860. The Catholic Church of the Holy Ghost is a fifteenth-century tithe barn converted by Sir Giles Gilbert Scott, and the Church of St John the Baptist keeps a fifteenth-century tower with seventeenth-century upper stages above a Gothic Revival body of 1830 to 1831. Both churches are Grade II* listed.

The last pit in the town, at Norton Hill, closed in 1966. The town that grew around coal is now a working centre with shops, offices, homes and public buildings, which means a roofer here meets a wider mix than in a village: pitched house roofs, flat roofs at the back of High Street premises, church roofs with lead in them and the occasional large span over a hall.

Each of those needs a different approach. We survey the roof you have, identify what is failing and why, and quote for the work that deals with it, whether that is a repair or something larger.

What we find

Hillside gutters, shop flat roofs and church lead

Overflowing gutters on sloping streetsWhere houses step down a hillside, one roof can drain onto the next. We trace the water from ridge to ground, clear the gutters and hoppers, and check that the joints and downpipes are carrying it away rather than spilling it down the wall.
Ageing flat roofs behind the shopsA flat roof to the rear of a High Street building often serves a stairwell, a kitchen or a flat above a shop. We look for ponding, blistered or cracked surfaces, failed upstands where the covering meets a wall, and blocked outlets.
Lead and stone on the church roofsLarge church roofs combine pitched slopes, valleys and lead-lined gutters, and their problems are usually in the details: a split in the lead, a displaced coping, a slipped slate beside the tower. We survey from a safe working platform, not from the ground.

Roofs on a valley hillside: where the water goes

In a town built up the sides of two valleys, a roof is only the start of the drainage path.

Rain landing on a Midsomer Norton roof has a long way to go. It runs down the slope, into the gutter, along to a downpipe, and from there into a drain that may already be carrying the run-off from the street. On a hillside town the whole chain matters, because houses sit at different heights and a fault high on the slope delivers its water to the property beneath.

The first thing to check is the gutter. Plastic gutters sag between brackets and cast iron gutters rust at the joints, and either will overflow if the fall has shifted. If water lies in the gutter at one end, the brackets have dropped or the run has lost its fall. Re-hanging on new brackets is often a smaller job than replacing the whole length, and we say which route fits.

Next, the downpipes and the hoppers (the open heads that gather water from gutter or parapet and pass it into the pipe). Leaves, moss and roof grit collect there first. When the head is blocked, the water has nowhere to go and finds a way out through the wall instead. We clear what we find and check that the pipe discharges to a gully or soakaway that works.

Then the roof edge. Slipped tiles or a failed first course at the eaves send water behind the gutter, onto the fascia and down the wall, and fixing the gutter will not cure that. We look at both together. On a terrace, where one gutter serves several slopes, we also look at the shared junctions, because these decide whether the repair holds.

The town's flood tunnel is a reminder that water has caused trouble here before. It is also a reminder of a limit: the tunnel handles the river, and a roof is drained by its own gutters and drains. If your property sees standing water at the foot of a wall after rain, the first thing to rule out is the roof edge above it. Our roof repairs service covers the work, from re-fixing tiles at the eaves to renewing a failed gutter.

High Street premises and the flat roofs behind them

Shops with flats above usually have a flat roof somewhere at the back, and it takes more punishment than it looks.

Walk behind a town-centre terrace and the picture changes. The front may be a pitched roof or a parapet, but the rear often has an extension, a stair tower or a lean-to with a flat roof, and that is where many leaks begin. Midsomer Norton's centre is a working one, with shops, offices and homes mixed together, so a leak from a flat roof can reach a trading floor or a neighbour's flat.

Flat roofs are covered by a membrane. Bitumen felt is the traditional choice, built up from several sheets and often heat-welded down. EPDM is a synthetic rubber sheet that can often cover a small roof in one piece, which leaves few seams to fail. GRP is glass-reinforced plastic, applied as a liquid resin onto the deck and cured into a hard shell. Lead is the heaviest-duty option, though it costs more and calls for skilled detailing. Each has its place, and the choice turns on the deck, the area of the roof and the foot traffic it must carry.

The covering is only part of it. The upstand is the vertical lip of membrane turned up against a wall, and it is where flat roofs most often fail. Cracks in the upstand, a loose flashing or a lifted edge let water behind the membrane and into the structure. The outlet is the second weak point: a small leaf guard or a blocked pipe can leave water standing, and standing water finds every flaw in the surface.

A parapet gutter (a channel running behind a low wall on the roof's edge) brings both problems together. Because it sits inside the building line, a leak there shows up inside the room before anyone sees it from outside. We check the gutter for splits and ponding and look at where it discharges.

Our survey on a flat roof includes the deck below the covering where it can be reached, because a wet deck cannot simply be sealed over. The flat roofing page describes the options, and the question of overlay or full strip comes down to what we find underneath.

Two churches, a tithe barn and the Town Hall: big roofs, careful work

Large public roofs ask for more planning, more access and a clear scope, especially when they are listed.

The oldest buildings in Midsomer Norton are not houses. The Church of St John the Baptist keeps its fifteenth-century tower, with seventeenth-century upper stages, above a body rebuilt in Gothic Revival style by John Pinch the younger in 1830 to 1831. The Catholic Church of the Holy Ghost began as a fifteenth-century tithe barn and was converted by Sir Giles Gilbert Scott. Both are Grade II* listed. The Town Hall, from 1860, and Island House, from the early eighteenth century, add further roofs of real age and size.

The roof of a building like these differs from a house in three ways. It is bigger, so the access is a project in itself. It combines several elements: slopes, valleys, gutters between roofs and often lead. And it belongs to a group, a congregation or a council, so decisions take longer and need to be written down.

We plan the survey around those facts. Before anyone climbs, we agree how the roof will be reached, from a tower, a cherry picker or a scaffold, and what has to be protected below. On the roof we record each slope, each junction and each run of lead, with photographs, so the committee can see exactly what is failing and where. The written report names the repair for each item and the order it should come in.

Because both churches are Grade II* listed, work on a comparable building starts with Bath and North East Somerset Council. The council asks owners to consult its planning team beforehand, and it keeps listed building consent apart from ordinary planning permission. We do not decide that for you, but we describe the work in enough detail for the conservation team to respond, and we match materials: natural slate stays slate, and lead is renewed as lead.

A converted barn raises a further point. A big roof that was once a farm building and now holds a heated space must cope with warmth rising into the roof, so ventilation and insulation need as much thought as the covering. Large lead roofs and their gutters are dealt with under lead roofing.

Choosing a covering for a commercial or flat roof

The membrane you choose sets the price, the lifespan and the detailing, so it deserves a proper comparison.

Owners of town-centre premises tend to ask the same question: which covering lasts, and what does it cost. There is no single answer, because the choice depends on the roof you have. A small rear roof over a kitchen, a long flat run over a row of units and a roof with plant on it each call for different things.

Start with the deck, the structure the membrane sits on. Timber boarding or plywood that is dry and sound can take any of the common coverings. Boarding that has been wet for a long time may need partly replacing first, and a membrane laid over a damp deck will fail early whatever it is made of. We open a small area where we can, or take moisture readings, before recommending a system.

Then consider the edges. A flat roof with a parapet needs a lined gutter or a drainage outlet, and one with an open edge needs a drip trim that throws water clear of the wall. Where the covering turns up against a brick or stone wall, the flashing or upstand has to be tied in properly. These details take most of the labour and decide how the roof behaves in practice.

Insulation is the third question. Where a roof is being renewed, the thermal performance of the new build-up may need to meet current standards, and this can change the thickness of the roof and the way the edges are detailed. We explain what that means for your roof at the survey.

On price, the typical UK ranges per square metre reported by MyBuilder in 2026 are shown below. They are national figures and not our quote: the fixed price follows the survey. For larger premises, commercial roofs are priced after a survey, and our commercial roofing page explains how that works.

Local questions

Shop, church and hillside roof queries in Midsomer Norton

Does the flood tunnel under the High Street affect how my Midsomer Norton roof is drained?

No. The tunnel, completed in 1977, carries excess water from the River Somer beneath the town centre. Rain from your roof leaves through your own gutters, downpipes and drains, so a roof job does not touch the tunnel. What matters is that your downpipes discharge to a working gully or soakaway, and we check that at the survey.

I own a High Street shop with a flat roof at the back. How would you survey it?

We go up to the roof, record the covering, the upstands, the outlets and any parapet gutter, and photograph each. Where we can reach the deck from inside, we check it for damp. The report names the cause of each leak and sets out the repair or replacement that fits, with a fixed price in writing, so you can decide without a second visit.

Do roofs on converted barns, like the Holy Ghost church, need special care?

They can. A large roof over a heated space has to handle warm air rising into the roof, so ventilation and insulation need to be considered along with the covering. If the building is listed, work also goes through the council. We describe each element of the roof in the survey so the people who manage the building can see what each repair involves.

How is roof work arranged on a busy street like the High Street?

Access comes first. Scaffolding or a hoarding over a public pavement usually needs the agreement of the highway authority, and a shop needs its entrance kept clear. We plan the access at the survey, talk through trading hours with you, and sequence the work so that the busiest parts of the roof are done when the building is least affected.
