Sika-Trocal provided the intricate profiling to enhance the character of a new church roof.

To create architectural consistency across the church’s roof at its peaks and valleys, crisp points and lines were introduced using Sika-Trocal detailing.

Licensed contractors Ithaca Roofing carried out the IPC roof installation. Its substrate comprised panels of 150mm thick CLT timber which sat within the steel frames and doubled-up as the finished ceiling material.

A total of 300mm of PIR insulation was mechanically-fixed, carrying the insulation over protruding steels and downwards towards lighter boxes and cables within the build-up.

Sika-Trocal laminated metal sheets were measured on site and profiled to the exact degree of each individual slope.

This ensured the roof area was at the same angle and height of the zinc-effect perimeter trim located over the brickwork edge, continuing across the roofline.

To secure the Sika-Trocal metal gutter detail in place without blowing the brickwork, installers secured 18mm ply to the inner skin and affixed a galvanised angle in line with the gutter tray.

Sika-bond was then used on the perimeter edge to the brickwork below the pressed, welted down stand.

The one piece Sika-Trocal metal was fixed to the roof area before it could be waterproofed. This was the only way to secure each 3 metre gutter tray around the perimeter.

Sika-Trocal sheets were lifted and glued into place with the laps ending where the décor strip would be fitted to eliminate the appearance of unsightly lines.

This part of the project merited a ‘Highly Commended for Best Detailing’ accolade at this year’s SPRA Awards; a revered industry tribute to the product and the contractor.
