The Thatcher
A Craft That Takes a Decade to Learn and a Lifetime to Master
Stand in any Cotswold village long enough and you will see it without looking for it. A roof that is not slate, not tile, not lead. A roof that looks like it grew there. Thick, golden, slightly rounded at the ridge, darkening to grey-brown at the eaves where the rain has weathered it over decades. A thatched roof does not sit on a building the way other roofs do. It wraps it. It gives the impression that the house and the landscape came from the same place, which in a sense they did.
Thatching is one of the oldest roofing methods in the world. In England it predates the Roman occupation. It was the default covering for almost every building in the country for the better part of a thousand years, from the humblest cottage to the grandest hall. It survived because the materials were local, the method was proven, and the result worked. A well-thatched roof sheds rain, insulates against cold, breathes in summer, and lasts - depending on the material - between twenty and sixty years.
What it requires, and has always required, is a thatcher.
The Material and the Method
There are three main thatching materials used in England, and a thatcher’s identity is bound up in which one they work with. The distinction matters more than outsiders realise. It affects technique, tooling, geography, and the character of the finished roof.
Long straw is the oldest method. The wheat is threshed by hand or machine but the stems are kept long and unbroken. The straw is wetted, drawn into bundles called yealms, and laid onto the roof in thick courses, each one pinned into place with hazel spars - twisted staples split from hazel rods. The surface is dressed with a leggett, a flat wooden tool studded with horseshoe nails, which pushes the straw butts up into a dense, even face. A long straw roof has a characteristically soft, flowing appearance. The straw lies at an angle, the eaves are rounded, and the ridge is often decorated with a pattern specific to the thatcher who made it.
Combed wheat reed is prepared differently. The wheat is passed through a comber - historically a reed comber, now often a drum machine - which strips the leaf and grain from the stem while keeping the straw perfectly aligned, butt-end down. The bundles are laid onto the roof butt-first, creating a much tighter, more uniform surface. The finish is crisper and more angular than long straw. This is the dominant material across much of southern and central England, including the Cotswolds.
Water reed - Norfolk reed, as it is traditionally known - is not straw at all but the stem of the common reed, Phragmites australis, harvested from wetland beds in winter when the plant is dormant. It is the most durable thatching material, lasting forty to sixty years in good conditions. It produces the sharpest, most angular roof profile. Norfolk and Suffolk are its heartland, but it is used across the country. Much of the reed used in England today is imported from Hungary, Turkey, or China, because the native reed beds can no longer supply the demand.
The choice of material is not arbitrary. It is determined by the building, the region, the listing status if the property is historic, and the tradition of the local vernacular. A thatcher in the Cotswolds works predominantly with combed wheat reed. A thatcher in Devon works with long straw or wheat reed depending on the parish. A thatcher in Norfolk works with water reed. To switch materials on a listed building without consent would be a planning violation. The material is part of the heritage.
The Apprenticeship
You cannot learn to thatch from a book. This is not a figure of speech. The Heritage Crafts Association, which maintains the Red List of endangered crafts, classifies thatching as a skill that requires a minimum of seven to ten years of supervised practice before a thatcher can work independently to a professional standard. Some in the trade say longer.
The knowledge is in the hands. You can describe what a thatcher does. You cannot describe how they know when it is right. The tension of a spar driven into the coatwork. The angle at which a yealm is laid so that water runs off cleanly and does not track inward. The compression of reed bundles at the eaves where the load is greatest. The way a ridge is formed - the cap that seals the apex of the roof - which is the most visible and most vulnerable part of the whole structure. These are things you learn by doing them wrong, being corrected, and doing them again. For years.
Most thatchers learn from their fathers. The craft has always run in families, partly because of the length of the apprenticeship and partly because no one else would tolerate it. A thatcher’s son grows up watching the work, carrying bundles up the ladder before he is old enough to lay them, learning the vocabulary of the trade - spars, liggers, sways, yealms, leggetts, eaves hooks - before he understands what each one does. By the time he begins his own apprenticeship he has already absorbed years of unconscious instruction.
The families are well known within the trade. In the Cotswolds, thatching dynasties go back three, four, sometimes five generations. The names appear on the same village roofs decade after decade. A thatcher will sometimes find, when stripping an old roof back to the timbers, the work of his own grandfather underneath - recognisable by the style of the sparring or the pattern of the ridge. That kind of continuity is rare in any trade. In thatching it is the norm.
A Day on the Roof
A thatching job begins long before anyone climbs a ladder. The thatcher surveys the roof, assesses the existing coatwork, decides what needs to come off and what can stay. A full re-thatch strips the roof back to the rafters. A re-ridge replaces only the cap along the apex. A repair might address a single section where birds, weather, or age have worn through the surface. Each job is different and the thatcher reads it like a doctor reads a patient.
The work itself is physically demanding in a way that is difficult to convey. A thatcher works on a ladder or a scaffold platform, often at a steep angle, for eight or nine hours a day. The bundles are heavy. The spars must be driven with force and precision. The leggett requires sustained effort across long stretches of surface. And all of it happens outdoors, in English weather, which means rain, wind, and cold for much of the working year. Thatchers do not work in winter if they can avoid it - wet straw does not lay well - but the season is long and the conditions are rarely comfortable.
A full re-thatch on a medium-sized cottage takes two to three weeks for a team of two. A large farmhouse or a long barn can take a month or more. The thatcher works systematically from eaves to ridge, building up the coatwork in courses, each one overlapping the last, each one pinned and dressed before the next is started. The geometry has to be right. A thatched roof is not flat - it curves over dormers, wraps around chimneys, sweeps down to the eaves in a continuous line. Getting that line right, maintaining the correct thickness and angle across the entire surface, is what separates competent work from good work and good work from exceptional work.
The Decline That Did Not Quite Happen
Thatching nearly died in the twentieth century. The same forces that killed so many rural trades - industrialisation, cheap alternatives, the drift of young people away from manual work - hit thatching hard. Welsh slate, mass-produced clay tiles, and eventually concrete tiles offered cheaper, faster, lower-maintenance roofing. By the mid-century, the number of working thatchers in England had fallen to a few hundred. The craft was in serious trouble.
What saved it was the listing system. When the post-war heritage protection framework was established, thousands of thatched buildings across England were given listed status. A listed thatched building must be maintained with thatch. The owner cannot strip the roof and replace it with tiles without listed building consent, which is almost never granted. This created a permanent, legally protected demand for thatching services that no market force could eliminate.
The listing system did not save thatching out of sentiment. It saved it by making the work necessary. There are approximately 60,000 thatched buildings in England. Most are in the south and west: the Cotswolds, Devon, Dorset, Hampshire, Suffolk, Norfolk. Every one of them needs re-thatching on a cycle of twenty to sixty years depending on the material. That is a lot of roofs. It keeps roughly a thousand working thatchers employed in England today - a number that has been broadly stable for the last two decades.
But stable is not the same as safe. The average age of working thatchers is rising. The number of young people entering the trade is not keeping pace with retirements. The apprenticeship is long, the work is hard, the early years are poorly paid, and there are easier ways to make a living. The Heritage Crafts Association does not currently list thatching as endangered, but it monitors it. The gap between “stable” and “at risk” can close within a single generation.
The Cotswold Tradition
The Cotswolds occupy a particular place in the story of English thatching. The region’s building tradition - honey-coloured limestone walls under thick coats of combed wheat reed - is one of the most photographed vernacular landscapes in the country. Villages like Chipping Campden, Broadway, Great Tew, and the Slaughters are defined as much by their rooflines as by their stone. Remove the thatch and the character of the place collapses.
The Cotswold thatcher works in a tradition that is visually distinctive. The roofs tend to be steeply pitched, which aids water runoff and extends the life of the material. The ridges are often flush-cut rather than ornamental, giving a clean, architectural line. The eaves are deep and neatly dressed. The overall impression is of precision - the wildness that long straw allows is replaced here by something more disciplined, more controlled. It suits the stone.
The wheat reed used in the Cotswolds was historically grown locally. Thatching straw is not the same as modern bread wheat - the stems are too short, too weak, too brittle. Thatching requires long-stemmed heritage varieties, grown specifically for the purpose, harvested with care, and processed without breaking the straw. As agriculture industrialised through the twentieth century, the acreage given over to thatching wheat shrank dramatically. Today, sourcing good English wheat reed is one of the trade’s persistent challenges. Some thatchers grow their own. Some have arrangements with local farmers. Some import. The supply chain is fragile in a way that is invisible from the road.
What Stays and What Goes
A thatched roof is not a permanent thing. It is a living surface that degrades and is renewed, over and over, across the life of the building beneath it. Some of the buildings that thatchers work on today have been continuously thatched for five hundred years. The walls are medieval. The timbers are Tudor. The thatch is this year’s, laid over the ghost of last generation’s, which was laid over the generation before that.
When a thatcher strips an old roof, they sometimes find layers of history compressed into the coatwork. Soot blackening from centuries of open fires. Fragments of the original long straw beneath later coats of reed. Old spars made from wood that no longer grows in the parish. The roof becomes an archaeological record of itself - every re-thatch a new chapter laid over the old ones, the building’s memory stored in straw and hazel.
The thatcher understands this. The good ones, the ones whose families have worked the same villages for generations, carry a sense of obligation that goes beyond the immediate job. They are not just covering a roof. They are maintaining a building’s relationship with its landscape, with its materials, with the long line of hands that came before. The straw comes from local fields. The spars come from local hazel. The skill comes from the man on the ladder, who learned it from his father, who learned it from his.
That chain is intact. For now. The question - as with every craft in this archive - is how long it holds.
