Thatch – much more than just picturesque

Victoria farm

Victoria Farm

I am fortunate enough to live in an old farmhouse with a thatched roof. Another house in the village here was being re-thatched recently, and it was fascinating watching the thatcher at work whenever we drove past… and it set me thinking about thatch and how, even in 2016, there are still so many thatched roofs around.

When I started investigating, the first thing I discovered is that although thatch is popular in Germany, The Netherlands, Denmark, parts of France and Ireland, there are more thatched roofs in the United Kingdom than in any other European country. On top of that, I found that Devon has more thatched properties than any other English county, so no wonder they seem quite commonplace to my eye!

Thatching materials can include heather, gorse, broom, flax, reed, rye and wheat straw. These light, but incredibly durable, materials were particularly used in areas, such as Devon, where buildings were made of cob or clunch that are less able to carry the weight of stone, tile or slate.

North Bovey

North Bovey on Dartmoor, a pretty thatched village.

The materials used for thatching were local and cheap. As I so often discover in my research, this ancient tradition was also very efficient and, while today we rush around being ‘green’ and insulating everything, thatch was doing a great job and ticking all the ecologically sound boxes from the outset! It is naturally weather-resistant and is also a natural insulator, and air pockets within straw thatch insulate a building in both warm and cold weather, so a thatched roof ensures your house is cool in summer and warm in winter. Thatch also has very good resistance to wind damage, so no flying slates to worry about!

Good quality straw thatch can last for more than 30 years when created by a skilled thatcher. Traditionally, a new layer of straw was applied over the weathered surface, and this ‘spar coating’ tradition has created thatch over 7ft thick on some very old buildings! The straw is bundled into ‘yelms’ before it is taken up to the roof and attached using staples, known as ‘spars’, made from twisted hazel sticks.


Thatching, a highly skilled trade.

Technological change in the farming industry had a huge impact on the popularity of thatching. The availability of good quality thatching straw declined in England after the introduction of the combine harvester in the late 1930s and the switch to growing short-stemmed wheat varieties. Increasing use of nitrogen fertiliser in the 1960s–70s also weakened straw and reduced its longevity so thatched roofs became expensive to build. Since the 1980s, however, there has been a big increase in straw quality as specialist growers have returned to growing older, tall-stemmed, ‘heritage’ varieties of wheat… as ever, the original way is so often the best!

Thatchers themselves, highly skilled tradesmen and much in demand, all have individual ‘signatures’ that are often seen in the way they treat dormers, eaves and gables. If you have thatched properties in your area, you might be able to spot these fascinating little details! You will also often see little thatched figures, such as a pheasant, created on the ridge of a new thatch. I think these are charming and really add to the appearance of a property.


A modern eco-house… with thatched roof!

Today, with the enthusiasm for energy conservation and minimising one’s carbon footprint, eco houses are being built with thatched roofs and hay bale walls… rather like ‘going organic’ and growing your own veg, nothing is new in this world!

    A delightful read 🙂
    Ive always adored thatched cottages. One of my favorite places is the Isle of Wight and they have losds.
    I used to collect Lilliput lane cottages and look at them now with the beautiful design and thatched roof and wish I could live there.
    Ps Growing up in Sussex my Grandparents lived in a lovely village and the local pub was called The Thatch.

    This is lovely Joanna and i’s quite fascinating watching the thatchers at work. Mum live in a very old thatched cottage in Dorset, it used to be the village shop and post office years ago and I believe it still has a license to sell alcohol even though it is no longer a shop! It has the most beautiful hollyhocks all along the front which touch the bottom of the thatch when they are in full bloom. I thought maybe you could do a hollyhock signature die (I couldn’t find one?) then I could print a photo of Mum’s cottage and put some hollyhocks in front of it! Being a card maker herself, she would love it!!xx p.s. it was great to see you back on TV!!

    Hi Joanna
    So many interesting facts about thatched roofs, when I win the lottery a thatched cottage is the first thing I’d buy.
    Hugs x

    Living in the suburb of a northern city (Leeds) thatched roofs are only to be seen on holidays down south or on the internet, It would be my dream to retired to a beautiful village with thatched roofs (as long as there in enough space for a craft room). I always thought of retiring to Cornwall (the land of my forefathers) but maybe Devon may be the way to go!
