What Should I Do If I Have Incorrect Roof Tiles For The Roof Pitch?

If the pitch of your roof is too shallow for the roof tiles, installing an EPDM rubber membrane can be an excellent solution to this problem.

Full Answer

Depending on the design of your roof and the available pitch angle, it may not be possible to use traditional roof tiles. 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. If you have an existing tiled roof that is leaking due to water blowing up under the tiles then a good solution is to replace the tiles with an EPDM rubber membrane. 

Installing an EPDM rubber membrane is a relatively straightforward process. Start by instaling a timber deck onto the existing rafters so that the rubber membrane can be bonded into place and finished off with the correct edge trims. It is important to ensure the roof structure has ventilation if the roof has traditional mineral wool installation in between the rafters. 

 

 

 

Leaking Roof Where The Pitch Is Too Shallow For Tiles

The breather membrane finally failed on this poorly designed roof causing it to leak.

EPDM Rubber Membrane Solution For Shallow Pitched Roof

A new OSB3 deck and EPDM membrane was the solution to this leaking roof.

If your roof pitch is too shallow for the choice of tile, but you still want the look of a tiled roof, then it is possible to install the tiles over a rubber membrane on counter battens. Check out our other roof tile article for more information.
