Can I Install Roof Tiles Over The Rubber Membrane?
Yes you can install EPDM under a pitched tiled roof. This may be necessary on shallow pitched roofs to prevent leaks.
Installing traditional tiles over a rubber membrane
The pitch angle of your roof will determine what type and design of the tile can be installed. Some modern interlocking roof tiles will accommodate a pitch angle as low as 15 degrees, whereas more traditional Rosemary or Victoria tiles require a 35-degree pitch minimum.
In this example, the client needed to install a traditional tile on a roof where the pitch was too low for the tile
EPDM membranes can be installed on any pitch of roof. However, in certain circumstances, it might be important for the roof to have a tiled finish. In the following steps, we will show how a roof can be waterproofed using an EPDM membrane and then have a decorative tile overlayed on counter battens to give the desired finish.
1. Install OSB3 Roof Deck on Appropriately Spaced Rafters
2. Install EPDM Membrane to shallow pitched roof
3. Fit Battens Using Appropriate Length Screws (Running Towards The Drip Edge)
4. Fit Counter Battens Ready for the Tiles to be Installed
5. Install Roof Tiles (Any water that runs under the tiles will run on to the EPDM membrane)
