Flat Roofing In Burnham-on-Sea And Highbridge: Prices, Housing Stock And The Somerset Council Question

Burnham-on-Sea and Highbridge run into each other along Highbridge Road and share one town council, but their roofs are nothing alike. Burnham is a seaside town with a Victorian front, a lot of bungalows and big estates behind them. Highbridge grew up around a wharf and a railway works, and it still has more small industrial units than you’d expect for its size. This guide covers flat roofing in Burnham-on-Sea and Highbridge from the point of view of someone paying for it: what each kind of roof costs, what the coast does to it, and which council you’ll be dealing with. That last one trips up more roofers than you’d think.

What flat roofing costs in Burnham-on-Sea and Highbridge

Prices first, because that’s usually why people ask. These are the ranges we work to for jobs in TA8 and TA9. Burnham is about fifteen minutes down the M5 from our yard in Weston, so there is no travel surcharge.

Typical job in Burnham or Highbridge	Usual range
Garage or carport, two-layer torch-on felt	£900 to £1,700
Garage, EPDM rubber in one sheet	£1,400 to £2,600
Bungalow or house extension, rubber	£2,200 to £4,000
Seafront bay top or balcony in GRP	£2,500 to £4,500
Insulation added during a re-cover	£45 to £80 per m²
One-off repair to a single fault	£180 to £600
Workshop or unit, single ply membrane	£70 to £120 per m², access extra

The range is wide because the price depends on what’s under the covering. Two bungalow extensions of the same size can be £1,000 apart once one turns out to have a rotten deck along the gutter edge. Our full flat roof price guide explains each line, and the Burnham-on-Sea area page lists the streets and villages we cover around the town.

The seafront and the older streets behind it

Burnham’s Victorian town sits close to the water, along the Esplanade and back through Pier Street, Regent Street and Victoria Street. Here the flat roofs are mostly small. You’ll find lead or felt on the tops of bay windows, asphalt or felt on balconies over porches, and narrow box gutters hidden behind parapets. A lot of the frontage has been turned into flats, which brings a further complication: when the balcony leaks, it’s often the flat below that gets the water, not the one that owns the balcony.

On roofs this small the materials are cheap, and most of the cost goes on access and on getting the detailing right. A bay top that’s two square metres still needs scaffold or a tower if it’s on the first floor. It also needs the edge, the wall abutment and the drip formed properly, otherwise water runs back under the covering. GRP is usually the best choice for a balcony you walk on. Where an existing lead bay is sound, we repair it rather than replacing it with something else.

Bungalow belts and postwar estates

Behind the seafront, and up the Berrow Road towards Berrow and Brean, Burnham has a lot of bungalows. Plenty were bought by people retiring to the coast and extended over the years, usually with a flat roof on the back. Highbridge and the edges of Burnham also have a good deal of postwar and later estate housing, with the usual flat-roofed garages, porch roofs and link-attached carports.

We price a lot of bungalow extensions in Burnham. These extensions are big, often 25 square metres or more, and many were built in one go, so the whole roof tends to wear out at once. When we strip them we usually find felt that has gone brittle, a chipboard deck that has swollen at the joints, and no insulation worth mentioning. So we nearly always quote these as a full re-cover in EPDM rubber with insulation added, not as a patch.

Estate garages are simpler. Many are concrete sectional buildings with a thin roof sheet or a felted deck. A garage used for storage can sensibly go back in felt, while a garage converted to a utility room or gym is worth doing in rubber.

Highbridge’s workshops and industrial units

Highbridge has always been a working town. It had a market, a wharf on the Brue and the Somerset & Dorset Joint Railway works, which closed in 1930 with the loss of about 400 jobs. The wharf took its last cargo of timber in 1948 and closed to shipping the following year. Today the commercial roofs are mostly on Walrow Industrial Estate, along Commerce Way and Evercreech Way, on the Isleport side of town, and on workshops and yards tucked in among the houses.

Unit roofs are priced by the square metre, and two things matter more on them than the membrane. One is age. Many 1970s and 1980s units have fibre-cement sheets, rooflights or bitumen layers that could contain asbestos, which was not fully banned in the UK until 1999. Whoever controls a non-domestic building has a legal duty to manage asbestos, so we ask to see the register before quoting. The other is drainage. Big flat areas push a lot of water into a few outlets, and a blocked internal gutter can soak the stock on the racking under it. Our commercial flat roofing page explains how we phase jobs so a business can keep running.

What Bridgwater Bay does to a roof edge

Burnham stands where the Parrett meets Bridgwater Bay, facing out over miles of sand with nothing to break the westerlies. The storm surge of December 1981 flooded Burnham with seawater, and the curved concrete sea wall along the front, just over a mile long, was finished in 1988 because of it. The wall keeps the sea out of the streets. It does nothing about the wind and salt.

Rubber and GRP shrug most of that off. The weak points are the metal parts and the edges: trims, fixings and flashings. Salt corrodes ordinary steel fixings, and wind lifts any edge that hasn’t been bonded and fixed properly. Seafront and Berrow Road jobs get stainless or aluminium fixings and edge trims glued and mechanically fixed. Highbridge has much less salt, but it sits on low, open levels land along the Brue with very little shelter. There the bigger concern is wind uplift on wide unit roofs, so our fixing schedules are worked out around it.

Somerset Council, not North Somerset

Weston-super-Mare, Uphill and everything up the coast to Portishead come under North Somerset Council. Burnham-on-Sea and Highbridge don’t. Until 1 April 2023 they were in Sedgemoor District. Sedgemoor was then abolished, and the new Somerset Council unitary authority took over planning and building control for the whole county apart from the north.

In practice that means a flat roof in Burnham or Highbridge goes through Somerset Building Control. That’s the partnership covering the old Mendip, Sedgemoor, Somerset West and Taunton, and South Somerset areas, with an office at Bridgwater House in King Square, Bridgwater. A full re-cover is normally building work that has to be notified, and it usually triggers the insulation requirements too. That is why the extension prices above include an insulation option. We’ve seen firms from further north send the notice to the wrong council. Ask anyone quoting which authority they’ll be dealing with. If they hesitate, that tells you something.

Planning works the same way. Burnham has a conservation area that dates from 1988, and you can check its boundary on the government’s planning data map of the Burnham-on-Sea conservation area. The two towns also have a neighbourhood development plan, made in 2018, which sits alongside the council’s local plan. A like-for-like re-cover rarely needs permission. Raising a roof, adding a balcony or changing what the street sees is when to check with Somerset Council’s planning service first.

Getting a quote you can compare in Burnham or Highbridge

Ask every roofer to price the same specification, or the cheapest figure won’t tell you much. That means the same covering, the same insulation thickness, the same edge trims, and a clear line on whether replacing the deck is included or charged extra. If one quote mentions the outlets and another doesn’t, ask about it before you choose.

We did a similar breakdown for the hillside villas and Kenn Road units in Clevedon, a town where nearly everything is decided by the age of the house. Burnham and Highbridge are different, because there the roofs are mostly decided by use: bungalow extensions people live under, small seafront roofs that are awkward to reach, and units with stock underneath. The survey covers all three, and it doesn’t cost anything.

Book a free flat roof survey in Burnham-on-Sea or Highbridge and we’ll measure the roof, look at what’s under the covering, and give you a written price with Somerset Council’s paperwork already accounted for.
