Top marks for SpecMaster on mixed ownership estate

According to Redland, employing the Redland SpecMaster service enabled Wigan Metropolitan Borough Council (MBC), which manages and maintains 22,000 homes, to benefit from a 15-year guarantee and avoid costly extras when it re-roofed 40 properties on one of its estates in Kitt Green.

This professional specification is said to have not only avoided unsightly and expensive detailing, but also accelerated the roofing programme through introducing the Innofix Clip, the award-winning tile fixing developed by the company.

Wigan-based BAAS Construction, who works in partnership with Wigan MBC on a design and build basis, has a long-standing relationship with Redland; and brought in the SpecMaster service to help Wigan answer both difficult design issues and provide the guarantees required for their client and stakeholders.

“The 15-year guarantee is important to us because it means that we shouldn’t have any unexpected financial burdens put upon us at Wigan within this period and in the unlikely event that there is a problem with the new roof covering, Redland will still attend site and rectify the issue free of charge,” project manager, Brian Hampson explained.

The 15-year guarantee that is provided when the tiles are installed with recommended fixings under the Redland SpecMaster service covers weathertightness, durability and design liability. SpecMaster is a free-of-charge roof specification service for architects and professional specifiers that covers slates, tiles, fittings, accessories, fixings, ventilation, underlay and battens – all in NBS-based format to integrate into any building specification. The service is also said to enable clients to work with the specification manager to achieve the optimum performance.

The gauging of the existing tiles was crucial as to whether re-roofing required the bonding gutter and the roof pitch dictated the required tile headlap but, once Baas Construction was on site, the Redland specification manager checked the roof pitch from the scaffold level and confirmed the pitch at 22.5o and the existing tiles were correctly gauged out with headlaps between 75 and 85mm – so bonding gutters weren’t needed.

The scheme was completed with the 50 double Roman tiles in Tudor brown and Innofix Clips used to fix the tiles, an innovation that impressed the roofing contractor, C&B Roofing, because they are so much quicker to fix and therefore speed up the contract.

Completely tool-free, the Innofix Clip is available for the entire range of Redland’s concrete interlocking tiles and was developed to meet the increased fixing requirements set out in BS 5534 British Standard Code of Practice for Slating and Tiling.

It is said to be the only tile clip available that doesn’t need a hammer, making it the fastest and easiest fixing on the market – up to 40% quicker than using traditional nailed clips says the company. Suitable for use throughout the UK, Innofix is said to be Redland’s “strongest clip yet”.
