What is Roof Sarking
Roof sarking, also known as ‘sarking’ or ‘to sark a roof’, is a pliable laminated membrane or material that is installed beneath roof tiles or other types of roofing materials. It is like a ‘second skin’ under your roof and can be installed when building a home, doing house extensions, or during renovations and roof repairs.
Common materials used for roof tile sarking include reflective foil laminates and synthetic breathable membranes The choice of material often depends on factors such as local climate, building codes, and specific roof requirements.
How Sarking Works
Sarking is rolled out in sections, either parallel or perpendicular to the eaves with an overlap between each layer. It protects the house frame from weather during construction, and offers ongoing protection from rain, dust, and condensation. It can also improve thermal performance.
More specifically, its functions include:
Waterproofing
Roof sarking acts as a waterproof barrier, preventing water from penetrating through the roof and reaching the underlying structure. This is particularly important in regions such as Brisbane where heavy rainfall, storms or where wind-driven rain is a concern.
Condensation Control
Sarking helps to manage condensation within the roof space. By providing a barrier between the roof tiles and the underlying structure, it can reduce the risk of condensation forming on the underside of the roof, which could lead to moisture-related issues such as mould or rot, especially on ceilings.
Thermal Insulation
Some types of roof sarking have thermal insulation properties, contributing to the overall energy efficiency of homes. This can help in maintaining a comfortable indoor temperature and potentially reduce heating and cooling costs.
Dust and Pest Protection
Sarking can act as a barrier against dust and debris, preventing them from entering the roof space. Additionally, it can deter pests, such as insects and rodents, from accessing the interior of the house.
UV Protection
In areas like Brisbane with intense sunlight and heat, certain types of roof sarking may provide UV protection. This can help in prolonging the life of the roofing materials and preventing degradation due to exposure to the sun’s rays.
Retrofitting Roof Tile Sarking
It is also possible to sark sections of a roof if they have been damaged or are leaking.
