Who can resist the laid-back ambiance of a tropical paradise? This is exactly the feel that tiki thatch huts, pergola bars and gazebos provide. So, it will not surprise you to learn that natural thatch roofing is becoming the most popular choice of roofing for new pergolas and gazebos along the coastline of Southern Spain.

Sustainable and long-lasting

Cape Reed’s thatch roofing is made from cape reed (Thamnochortus Insignis), a sustainable carbon negative natural material that can help you or your business reduce your overall carbon footprint. However, like all natural substances it will need to be well maintained and at some stage repaired. In the case of natural thatch roofing, this means re-thatching.

High density stable and strong reeds

First, let’s go back to what we mean by thatch roofing. Cape Reed uses a type of reed that grows specifically in the Southern Cape of South Africa. We only harvest and use reeds that are at least 6 years old to ensure maximum strength, stability and density, which makes it much more resistant to rot and decay. This is why we guarantee our thatch roofs for 15 years, when regularly maintained.

Regular inspections and maintenance

As with any roof, you want to make sure that it is fit for purpose and hasn’t succumbed to the elements. How the structure performs is different depending on heat and humidity. Even though we guarantee our cape reed thatch roofing for up to 15 years, we recommend that you should get your thatch roofing inspected by a professional regularly, at least every 5 years.

A site inspection is crucial in order to ascertain the condition of any thatch roof, Cape Reed’s team is always happy to arrange a visit to assess whether any remedial work is required.

When to re-thatch your gazebo

If thatch is not maintained correctly, be it your thatched gazebo, pergola or pool entertaining area, this will reduce the longevity and appearance of the structure. Regular inspections can identify any weak or damaged areas, allowing the experts to make the necessary repairs.

All thatch repairs are different, quite often it is simply the top coat that will need to be replaced. When an area of weak or rotten thatch is identified during an inspection, Cape Reed’s thatchers can carefully remove, replace and compact the damaged section. In some cases, it could be that the entire structure, including the supporting wooden beams, needs replacing. However, it is important to remember, like any material and structure, performing regular maintenance enables you to identify potential issues before they become big problems, restoring the structure so that it can last for many years to come.

The cost of rethatching roofs will depend on a number of factors, such as size, materials, location and the amount of work required. Therefore, it is necessary to request a professional inspection and a personalised quote.

Fireshield fire retardant treatment

All of Cape Reed’s thatch roofing is constructed with the addition of ‘firebloc’, a fire-resistent cloth which is interwoven into the thatch during the construction and repair processes. This unique fire-resistant material can withstand and resist temperatures of up to 500 degrees centigrade.

To further enhance the flame-resistance qualities after all maintenance work has been completed, Cape Reed’s Fireshield, a non-toxic fire-retardant coating is also sprayed at high pressure to coat both the internal and external surfaces of the thatch.
