ISOLINE LOW LINE For Refurbishment & Renovations

Renovating an aging roof is rarely straightforward. Stripping away old tiles often reveals uneven timbers, compromised structures, and the high cost of buying entire batches of matching replacement tiles.

Furthermore, simply replacing old roofing felt with new membrane doesn't solve the core issue: if an old tile cracks or slips in the future, the roof will leak again. Refurbishments require a system that adds structural reliability, maximizes material reuse, and speeds up installation times.

ISOLINE LOW LINE is the ultimate upgrade for roof renovations. It turns a standard reroofing project into a high-performance, dual-layer roofing system.

It is designed to be installed directly over existing rafter structures, smoothing out minor imperfections and creating an immediately watertight sub-roof. This allows contractors to take their time finishing the top tile layer without worrying about sudden weather changes.

Save Money, Reduce Waste: Because ISOLINE LOW LINE is guaranteed to be waterproof on its own, you can safely reuse your original, weathered tiles - saving thousands on materials while retaining the building's established character.

• Immediate Weatherproofing: Once fixed to the rafters, the building is dry and weather-tight, protecting interiors while the final tiling takes place.
• Lightweight Advantage: At just a fraction of the weight of alternative boarded systems, it adds virtually no dead-load to older, fragile roof timbers.
• Fewer Tile Replacements: Cracked or slightly porous tiles don't need to be discarded. The sub-roof catches any moisture, meaning you only replace tiles that are structurally broken.
• Long-Term Asset Protection: Upgrades an older property to modern building standards, drastically increasing the lifespan of the entire roof build-up.

1. Expose & Repair: Strip away old, failing tiles and degraded underlay, exposing the rafters.
2. Instant Waterproofing: Fasten corrugated ISOLINE sheets directly to the rafters. Once secured, the building is immediately watertight, keeping the interior fully protected.
3. Batten & Slate: Fix traditional timber battens directly over the corrugated sheet peaks, then lay your new or original weathered tiles.
4. Successful Drainage: If any wind-blown rain or condensation slips past the tiles over the coming decades, it is safely funnelled down the sheet valleys and straight into the guttering.
