Upon first visit to this stunning residential home in the small town of Joubertina, we were struck by the impressive roof design with its high pitch, straight angles and edges which is uncommon in thatched homes that are not based on the traditional Dutch style seen in Cape St. Francis and the Western Cape.

It was these straight angles and edges that enabled us to design the roof conversion around the use of Aluzinc roof sheeting as opposed to the flexible roofing tiles that we most often use. Commonly thatched roofs are shapely with lots of curves and irregular angles meaning that a less pliable roofing solution is not appropriate for use in a conversion.

The thatched roof, of approximately 280sq.m in size, was in a fairly good condition and after a brushing to remove any external rotten material, was in an appropriate state to use the over-sheeting method to convert the roof. The lightweight timber structure was fitted over the original roof and then Aluzinc roof sheeting fixed to the timber.

The team worked at the exact finishing of the roof especially around the dormer windows in the roof and when fitting the fascia boards, to ensure a neat and tidy aesthetic.

The thick thatch layer under the Aluzinc ensures great insulation properties for the home in both the summer and winter months.

    1. Hi Eugene!

      Thanks for reading our article and taking the time to comment and connect with us – we do work nationwide but it depends on the size of the job. Would you mind emailing us a few more details so that I can ascertain whether we can assist?

      My email is info@bosazzaroofing.co.za.

      I look forward to hearing from you,

  1. Good day this really looks like a good option. so the metal roof just goes over the thatch without removing any thatch? also if one does this does your insurance reduce as that would be a major saving over time?

    1. Good morning Bernard,

      Thanks for taking the time to read and comment. The roof sheeting is installed over the thatch if the thatch is in an appropriate condition. It then also keeps the natural insulation properties as well. Another benefit of this system is that the entire roof doesn’t need to be stripped when re-roofing which is obliviously very disruptive to the home while the job is being completed. However an important thing to consider when thinking about converting your roof with this system is the current condition of the existing thatch; unfortunately if the thatch is severely rotting or old we cannot over sheet as it will continue to rot beneath the roof sheeting, causing more problems than it did before.

      With regards to insurance implications, most insurers will reduce the cost of cover when you convert the roof. They require the thatch layer to be reduced in thickness and fire protected before it is over-sheeted.

      Do you have a roof that you’re considering converting?

      I look forward to hearing from you,

        1. Hi Eddie,

          I hope you’re well! The over-sheeting system is only used when the existing thatch is in an appropriate condition. If it is in a bad condition we would recommend removing the thatch completely. I sent an email to your inbox to see if you’re considering a conversion – I see that your lodge is currently thatched?

          I look forward to hearing from you,

  2. Hi, just thinking about the possibility of this for a design for a restaurant – want the ambience of thatch internally, but the look of corrugated steel roof sheeting outside ……as well as long term durability.
    Is there a standard design detail? Keeping in mind that this would be for a completely new building.
    Thanks, Kevin.

    1. Good afternoon Kevin,

      Apologies for my slow reply – and thank you for reading and reaching out with your inquiry. I love the idea of using the thatch ceiling on the inside and a corrugated roofing on the outside. When we install thatch ceilings we install a thin layer of thatch just to give the rustic effect of being inside a thatched place. If you were to use corrugated roofing you would also need some kind of insulation between the thatch and the roof sheets to ensure that the restaurant is properly insulated and has an appropriate R-rating. Do you have plans for the building or a sketch with rough dimensions?
      If so you could email them through and I will ask Jonathan to put thought into the specifications of the roof covering.
      And also – where are you based?

      Many thanks,

      April
