Roofing felt fails by embrittling and cracking, as a result of Ultra Violet degradation, differential thermal movement or delamination caused by blisters of entrapped substrate moisture.

Joints also fail, particularly at upstands. Each of these defects allows water to penetrate into the roof substrate.

Decothane has a proven longer life span than felt. It offers total weatherproof protection for at least 25 years, remaining totally protective against the elements without exhibiting any signs of embrittling or cracking.

When maintenance is eventually required, the surface simply needs to be washed down before a single coat of Decothane is applied to restore the original performance and life span.

Decothane is applied by brush to parapets, upstands and other detailed work, before being applied to the complete roof surface, spread with the aid of a roller or airless spray. The finished Decothane system is totally seamless, elastomeric, fully bonded and able to withstand thermal and structural movement without cracking or flaking.

Resistant to abrasion and impact damage, it has a very tough, hard-wearing surface. It is able to tolerate foot traffic and attack by airborne pollutants and other aggressive chemicals, and will not degrade with prolonged exposure to ultra-violet light.

When felted roofs require refurbishment, vegetation growth is visible at the failed joints. Unlike Decothane, felt needs to be totally stripped out and replaced. This process is time consuming, messy and requires disposal of the failed felt. In order to bond the new felt to the roof, hot bitumen is poured and spread across the substrate, before the felt is laid with the aid of a roof flame torch.

The heating equipment used to heat up the bitumen and flame torch pose a significant health and safety risk. Specifiers, contractors and end users simply needn't take that risk, as Decothane is the safer, more effective roofing solution.
