Long-Lasting Protection for Roof tiles with LUL APR Roof Protection and Repair products
Designed to resist corrosion and withstand vibration, this coating is part of our roof repair products range built for London Underground infrastructure. It provides instant waterproofing and a highly effective seal, helping to extend the life of older roof tiles commonly used in rail and public sector settings.
Why Use LUL APR Roof Coating for Roof tile Protection and Repair products
Choosing from our London Underground Approved Products ensures your coating system meets the strict test and compliance standards in place for rail infrastructure. These aren’t standard roof coatings – they’re coatings tested for performance under difficult weather conditions and constant use.
With LUL APR Roof Protection, you get a durable coating system that actively protects surfaces from corrosion, water ingress, and UV breakdown – common issues affecting roof tiles, lead flashings, fibre cement panels and composite materials. It’s suitable for use on both flat and pitched roofs, and ideal for roofing materials where insulation and surface durability matter.
Unlike a general paint or decorative coating, this system has been developed to prevent regrowth of algae and moss while sealing over gaps, minor cracks, and damaged areas. That means fewer maintenance cycles, longer lifespan, and less downtime for essential buildings. It's also available in eight popular colours, offering a professional finish that fits with a wide range of roofing materials.
Rail Roof Coatings Strategy for Flat Roofs, Roof tiles and Repair products
For any roof within the London Underground network or other transport-linked buildings, it’s not just about the topcoat – you need a complete system that includes a primer, topcoat, and prep to handle heat, weather and substrate movement. For steel substrates, for example, we recommend Tikkurila Rostex Super Akva Primer, which provides a strong bond and helps prevent rust and corrosion from forming beneath the coating.
When applied as a full system, LUL APR Roof Protection seals and protects surfaces from long-term moisture damage and the slow erosion often seen with clay tiles, asphalt coverings, and older roof tiles. Whether you're dealing with a leaking platform roof, a tunnel entrance, or garages and maintenance buildings, this system covers all aspects of protection – including roof supports, flashings, gutters and rooflights.
For added strength and convenience, this product can be used alongside other roof repair products, including:
-
Concretal Lasur – for weathered or porous concrete surfaces
-
Flag Roofix 20‑10 Roof Repair – for instant waterproofing and sealing cracked surfaces
-
Tikkurila Rostex Super Akva Primer – for long-term adhesion on metal substrates
Extend the Life of Older Roof tiles with Professional Roof Repair products
Using a certified roof coating like LUL APR Roof Protection does more than just improve appearance. It prevents regrowth of algae, seals out moisture, and helps prevent thermal movement from damaging your roof tiles. The coating is also durable under high UV exposure and changing temperatures, making it a reliable choice for busy, high-impact areas such as public walkways and industrial buildings.
Because the system is designed to reduce cracking and slow organic growth, it helps lower repair frequency, minimise replacement costs, and support long-term safety – especially in older assets. It also supports insulation and helps reduce heat loss through worn or damaged substrates.
With a full stock available and a wide range of colours, our LUL APR Roof Protection solution is ideal for transport projects that require certified performance and visual consistency. For areas with prior damage or cracks, use a compatible repair product first before applying the system to ensure adhesion and coverage.
