Thatch Performance

The performance of Thatch depends on many factors including roof shape and design, the pitch, its position geographically, the quality of material and the expertise of the Thatcher. Figures for the expected life span of thatch can only ever be approximately given after examination of the individual circumstances. However, the life of thatch can be extended significantly by appropriate repair and maintenance.

General Information

Thatch does not (when working properly) absorb large amounts of water. Any water striking the apex is transferred down the roof surface from stem to stem till it falls from the eave. When water penetration occurs it is minimal and usually due to capillary action.

Thatch is not by its nature prone to wind damage and is proven to be sufficient than other roofing materials.

Netting and Moss

Long straw thatching should always be securely netted to prevent bird penetration (as is sometimes the case with Combed Wheat and some Water Reeds). We would always advise on this.

The presence of moss is not necessarily detrimental to the thatch. It can in some cases appear unsightly, and if required, can be removed by us in the most appropriate manner for the individual roof.
