Description The Manthorpe GDRR-CL Roll-Out Clay Ridge is a mechanically fitted system which securely fixes the ridge tiles on to a roof and provides 5,000mm/m ventilation to the batten void or roof space through the vent roll, which is the equivalent to a continuous 5mm gap. The GDRR-CL system does not require mortar fixing, making the installation process quick, easy, and clean. As there is no need for mortar it is also possible to install during frosts and other adverse weather conditions. The system is designed to suit traditionally deeper clay ridge tiles (both round and angled), but is also compatible with concrete ridge tiles and can be fitted onto most roof coverings, including profiled tiles. The system is designed to fit a duo pitch roof which has a pitch between 15 and 45 degrees. This system can be used in conjunction with Manthorpes Ridge End Caps, as well as SmartVerge and Linear Dry Verge systems.
