Whether you are planning a new build or a ‘strip and re-sheet’ repair, composite roof tiles are an opportunity to improve the colour, texture and style of the building, and its thermal performance at the same time.
Composite roof tiles properties
By definition, composite roof panels, tiles or sheets are composed of more than one material, but a base of about 80% asphalt is standard. The other 20% is usually chips of slate, schist, quartz, or ceramics. Other common materials include adhesives and additives to improve resistance to moss, ultraviolet light, weathering, peeling and warping.
Today, composite roof panels can also be made in almost any size, colour, shape or texture. Many deliberately resemble traditional materials such as regional varieties of slate and other traditional roofing tiles.
Environmentally friendly composite sheet formulas are being more commonplace – such as hemp fibres, and recycled plastics. Up to 95% are certified recycled.
The quality of materials used in composite roof tiles makes a big difference to their durability. A good quality composite roof can easily last over 50 years – two or three times longer than an ordinary shingle roof. Thicknesses of up to 100mm and varieties layered with steel are available for commercial and structural applications.
Old composite roofing
If you are replacing an older composite shingle roof, you need to be aware that many used to incorporate white asbestos fibres. These have to be removed carefully and dealt with in accordance with the current asbestos handling regulations.
