This is prevented by sealing the gaps, traditionally with lead, which is still the most common material used. Sheet lead comes in a range of codes, as defined by the Lead Sheet Association (LSA). These depend on the thickness and weight of the sheet, and each code is recommended for specific uses, allowing the correct tolerance for expansion and contraction due to temperature variation.

Both lightweight and resilient, our built up flat roofs are designed to prevent any settlement cracks from reducing its waterproofing effectiveness. CWG Group works only with the leading suppliers of built up flat roofing systems, such as Bauder, Langley, Alumasc and Radmat. These systems are accredited by a vast range of major industry bodies and are widely recognised as being industry leaders.

read moreAt CWG Group, we provide both extensive and intensive green roofing systems from leading manufacturers Bauder and Langley. Extensive green roof systems are aimed at those who want to use their flat roof to encourage biodiversity and provide insulation without requiring regular access to the roof. These systems use the succulent sedum to provide an excellent, low-maintenance covering which will increase protection to the waterproofing system. The plants are grown on a blanket that's harvested like turf.

This will enable us to help you decide which of the many roofing materials will best suit your property, both practically and aesthetically. Clay tiles have been the most popular roofing material in the UK for centuries, and there are very good reasons why. They're relatively cheap compared with many other materials, versatile, hard-wearing and easily replaced if a single tile is cracked or blown off.

read moreAsphalt (also known as mastic asphalt) has been used as a roofing material for centuries and offers excellent waterproofing. It's manufactured by combining limestone and bitumen, and is most commonly used as a hardwearing, waterproof surface for roofs, balconies and many other structures. Polymer modified asphalt (PMA), created by adding a polymer to the mix, is more effective in terms of both wear and waterproofing. Tests have shown that it resists wear from wind, rain and hail at a considerably higher level than traditional mastic asphalt.
