Installation Guide for Porcelain Tiles on Rooftops

December 2025

Installing porcelain tiles on rooftops can transform your outdoor space into a stunning and functional area. With the Raaft® Terrace System, this process becomes simple and efficient.

Step 1: Prepare the support structure
A solid foundation is crucial for a safe and sturdy terrace. The Raaft® system is ideal for rooftops, which are often uneven.

Begin by installing the robust Raaft® steel pedestals, which are designed for easy installation and provide excellent support for the modular terrace system.

Step 2: Install the substructure
Next, lay down the Preventa® aluminium substructure joists. These 30mm & 50mm joists create a stable platform for your porcelain tiles.

The aluminium construction ensures durability and fire resistance, meeting UK building regulations and fire safety standards.

Step 3: Choose your porcelain tiles
Select your preferred Atria® Porcelain Tiles. These tiles are available in various styles, colours, and finishes, allowing you to customise your rooftop terrace to your liking.

The Atria® tiles are designed to work seamlessly with the Raaft® Terrace System, ensuring a perfect fit.

Step 4: Lay the tiles
Carefully place the porcelain tiles onto the aluminium substructure. The modular nature of the Raaft® system makes this process straightforward and efficient.

Ensure each tile is properly aligned and secure.

Step 5: Add finishing touches
To complete your rooftop terrace, consider adding Raaft® planters. These steel planters are available in standard and bespoke options, perfect for creating a garden-like atmosphere on your rooftop.

They're designed for easy installation and complement the overall Raaft® Terrace System beautifully.
