OS-RFT-059 is a ventilated ridge-and-hip roll for the junctions that complete a tiled roof. The surface shows a dark central strip bordered by lighter ribbed edges, supplied in rolled form. Its documented purpose includes ventilated detailing and mortar-free ridge-tile installation, providing a route for hot-air exhaust within the planned roof system. The profile and colour contribute to the roof’s appearance alongside exterior walls, eaves and surrounding architectural materials.

Heat-reflective roof underlay
550μm
OS-RFT-057 is a heat-reflective roof underlay with a thickness of 550μm. The surface shows a reflective silver sheet presented between dark rolled edges, distinguishing this concealed roofing component from the decorative roof covering. It is intended beneath roof tiles as part of the roof assembly. Laps, sealing and ventilation belong in the installation design.
Radiant-barrier underlay
A silver reflective sheet is shown unrolling from OS-RFT-058, a radiant-barrier roof underlay intended to limit radiant heat transfer beneath roof tiles. Its role is within the roof construction, rather than as an exposed decorative finish. Performance depends on the designed air space, installation and complete assembly. Select the material within a complete installation system, with its supporting structure, joints and exposure considered together.
Corrugated ridge sealing tape
Fine corrugations run across the orange strip shown for OS-RFT-060. This ridge sealing tape is intended to follow profiled roofing materials at ridge details, with an adhesive surface supporting mortar-free finishing when installed correctly. It is a functional roof-junction component whose fit should be considered alongside the tile profile. The profile and colour contribute to the roof’s appearance alongside exterior walls, eaves and surrounding architectural materials.
Flexible abutment flashing
The red flexible strip with OS-RFT-061 is an abutment flashing for transitions around sidewalls, chimneys and roof intersections. Its purpose is to form the connection between roof tiles and adjoining construction, making it part of the junction detailing rather than the main roof covering. Select the material within a complete installation system, with its supporting structure, joints and exposure considered together.
