our story

Husband and wife team, John and June Smith, founded Biggarsberg Thatchers in 1996. Since a very young age, John Smith admired thatch roofs and in later years took his love for these unique types of roofs and built his company based in this sector. Our thatching company consists of a vibrant and well-equipped team, which includes Mr and Mrs Smith’s son, Shaun Smith (partner & branch director) as well as Jannie Marx (site management) and Ena Marx (admin).
The company has built a strong reputation for being one of South Africa’s most sought after thatching company within the Kwa-Zulu Natal and Free State roof thatching industry, having earned various awards including the 'Best Thatched Roof in the World' Award 2014 which saw competitors from 8 different countries and 72 entries.

meet the team


John took his love and intrigue of thatched roofs, which he had had since his youth, together with his instinctive knowledge and ‘feel’ for building and distinct flair for thatch roof design to start up Biggarsberg Thatchers.
He is proud to say that the profession of good thatching is not something that comes from formal education, but from passion and years of dedication and experience.

Being the past National Chairperson for the Thatcher’s Association of South Africa (TASA), John is passionate about not only the thatching that he and his company are involved with, but in the thatching industry as a whole. He was the integral force behind the creation of The Guide to Thatching in South Africa published which was published in 2016 and is a committee member on the SABS standards team regarding all matters related to the thatching industry and is thus always up to date and informed of the latest requirements and regulations of the board.

Wife and partner in the company, June has been involved in the harvesting process since 1988 and has been an integral part of the business since its inception as Biggarsberg Thatchers in 1996.
June ensures that the quality of the grass which is harvested off their farm, neighbouring farms and various areas within a 100km radius is kept to the highest standard of quality.

Apart from being involved in the thatching business June also runs a B&B and self-catering accommodation business on their farm. The latest project which she has undertaken is ‘Thatcher’s Barn Theatre’ a converted shed in which shows and dances are held in order to raise funds for various charities.

Shaun, son and partner in the company, manages the Hillcrest Branch and also runs and oversees the Phezulu Game Estate project. With the name and good reputation of Biggarsberg Thatchers becoming known throughout KZN, Shaun has found himself travelling far and wide running the sites in areas in the Midlands and northern and southern coastal regions including Kokstad and surrounding areas.

Shaun spent many weeks in Portugal thatching lapas and entertainment areas. He is responsible for the pole construction design of all the roofs constructed by Biggarsberg Thatchers and is also responsible for the site management of all his projects.

Jannie, who for 27 years as a train driver for SpoorNet one day decided that he needed a ‘real change’ so, along with his wife Ena they joined Biggarsberg Thatchers in 2007.
Jannie’s extremely conscientious approach to his work ethic soon had him firmly entrenched within the company. Under John’s guidance, Jannie soon became most proficient in the understanding of the technical aspects of thatching.

Jannie is a most jovial, efficient and staff motivational site manager, who holds the name and reputation of Biggarsberg Thatchers utmost in his mind at all times. His constant presence and surveillance on a site ensures total customer satisfaction in all aspects.

Ena, who had previously been employed in the corporate sector, joined the Biggarsberg Thatchers team and took over the administration duties within the company.
Not content with just ‘being in the office’ Ena soon got involved in the harvesting side of things and more than proved her worth in the thatch quality control, and organizing and distribution of the ‘Harvesting Ladies’ from Tugela Valley.

Ena, along with hubby Jannie can very often be found on site doing a ‘ jolly good job of ‘snagging’ and is also often involved in the final ‘housekeeping’ of a site, ensuring, once again, that the client is as satisfied as possible.

  • All gum pole structures to buildings 6m and wider will be subject to engineer’s approval. This will form part of the fee paid by client to the Engineer.
    All free-standing structures i.e. Lappas will require Engineers approval and certificates.
  • The diameters specified shall be the size measured at the thin end of the gum pole.
  • Pole ends will be nailed with anti-split plates.


  • A minimum pitch of 45° (but preferably 50°) will be maintained throughout. However, on rare occasions 40° will be allowed over dormer windows only.


  • 16mm galvanized thread bar will be used for all major connections.
  • 12mm galvanized thread bar will be used for all rafter connections.
  • All joints will be drilled and fixed with galvanized threaded bar and no nails will be used for this purpose.
  • Cross-tonguing joints shall be used on all gum poles which are unobtainable in the lengths required.

UPRIGHTS - Size of poles for free standing structures

  • Buildings over 10.1 meters wide will have 250/275 diameter posts fixed with 20mm thread bar.
  • All uprights will be spaced at no more than 3.5 meters apart unless a lattice beam system is used (Subject to engineers’ detail).

RING BEAMS - Size of poles for free standing structures

  • Buildings up to 6.0 meters wide will have a 150/175 diameter ring beam.
  • Buildings between 6.1 and 9.0 meters wide will have a 175/200 diameter ring beam.
  • Buildings over 9.1 meters wide will have a 200/225 diameter ring beam.

RAFTERS - Size of poles for all structures

  • A double ridge pole system will be used.
  • All buildings up to and including 8m will have 100/125 diameter rafters, spaced at 900 centers or less.
  • Buildings 8.1 to 12.0 wide will have 125/150 diameter rafters, spaced at 900 centers or less.
  • All rafters will be secured to walls using a double strand of 4mm wire.
  • No hoop irons will be used.

LATHS - Size of poles for all structures

  • The thickness of all laths at their thin ends will range between 25mm and 38mm and will be nailed to rafters at minimum 250mm and maximum 270mm centers using 4” nails.
  • Only the first row at the eaves and the last row at the ridge will be at ±150mm centers.


  • Only guaranteed frost cured, fully grown thatch grass of the Hyperrhenia Hirta species which has been cleared of all leaf and sheath residue and which is free of mould will be used.
  • The thatching grass will be beige/yellow in colour and shall have a maximum body moisture of 10% to 15% by mass.
  • Only straight pieces that have been cut above the first notch will be used.
    The grass will be 800mm to 1500mm in length, with the ends ranging from 2mm to 3.5mm diameter.
  • We will ensure that all seed ends of back thatch (sprei laag) are covered thus ensuring the uniformity of the colour.
  • All grass stems will be concealed by laths.
  • We take special care in storing and stacking thatch grass on site, by placing the bundles off the ground and under cover.
  • Roofs will be thatched to a thickness of between 175mm and 200mm which is measured at right angles to the roof.
  • All roof valleys will be fitted with galvanized valley liners, or aluminium in coastal areas.
  • Stitching will be done using a double strand of sisal tar twine with a maximum stitch width of 110mm.


  • Thatch at the roof apex will be bent over the ridge of the roof and fixed to the opposite side of the existing gum pole laths.
  • A cement mixture of 4:1 i.e. 2 wheelbarrows to 50kg bag will be used.
  • 250 Micron plastic will be used as an underlay to the concrete and cut to cover the last stitch of twine only. A minimum space of 100mm will be created at the end of the capping to ensure that the cement mix binds with the underlying thatch.
  • 25mm x 0.9mm netting wire to extend over entire width of capping.
    50mm thick cement capping to extend over the last layer of thatch ensuring that the butt ends are secured by the capping (this ensures that birds are unable to pull the thatch from under the ridge). Capping to be floated to a smooth even finish.
  • Expansion joints at no more than 3m apart.


  • One needs to understand the technical detail of a thatch roof before you merely let a unqualified Thatcher comb a roof. Every combing process unless properly done, reduces the cover over the sway in other words the functional thickness of a roof and thus lifespan. For functional thickness (see photo 1 below).
  • The correct procedure is to inspect the general length of the thatch or reed. If found long enough, the next step is to pull down the thatch layers (see photo 2 below).
  • The binding twine then needs to be tightened on the underside of the roof (see photo 2). Only then can the combing process begin.
  • It is advisable that this process is well supervised as a uninformed and inexperienced Thatcher will take the shortcut and ultimately destroy the roof.


  • Twenty-four (24) months guarantee on defective workmanship and materials.


How long will a newly thatched roof last?

This depends upon many factors, eg:

  • The pitch of the roof should be no less than 45 degrees.
  • The humidity in the area.
  • It depends on the original quality of the materials and workmanship.
  • Shadowing from large overhanging trees.
  • Proper maintenance by qualified persons. Combing by unqualified persons can drastically reduce the lifespan of a roof.

If all of the conditions are ideal the average lifespan of a thatched roof would be between 20-25 years.

How often does a roof need to be maintained?

Maintenance is once again dependent upon various factors, eg:

  • Hot and dry conditions, approximately every 10 years.
  • Humid areas and conditions, approximately every 5-7 years.
  • After heavy hail storms the roof should be inspected to determine if maintenance or repairs are necessary.

Depending on the severity and extent of the damage this can be claimed from your insurance company.

What fire prevention methods are there for thatched roofs?

  • Drenching systems.
  • Fire blankets.
  • Smoke detectors.

Can a normal tiled roof be replaced with a thatch roof?

Yes. A normal tiled roof can be replaced by a thatch roof. Certain and definite requirements and changes to the roof structure would be necessary and would have to be discussed with Biggarsberg Thatchers.

Are the insurance costs of having a thatched roof much higher than a regular tiled roof?

The cost of insurance is higher on a thatched roof but not by an exorbitant amount.

Insurance companies will take into account the number and type of preventative measures which have been put in place. Eg:

  • Concrete ceilings over kitchens.
  • Drencher systems installed.
  • Fire blankets installed.
  • Early warning systems. eg: smoke detectors.
  • Hose reels/fire extinguishers installed in strategic areas around the building.
  • Proximity to the closest fire station.

What are the benefits of a thatched roof?

  • Aesthetically appealing.
  • Natural insulation and therefore saving on electricity bill for both heating and cooling.
  • Sustainable materials.
