Question: 

We are going to be installing new skylights into a listed barn, it has a fairly shallow catslide roof on one elevation. Would the Lumen Conservation Rooflight be suitable for this application.

Answer: 

Lumen conservation stock sized rooflights can be used from a minimum pitch of 17 degrees to a maximium of 70 degrees.
Installation into lower than 17 degrees may cause issues with removing water from the outer frame area, particularly in a pantile roof. Although it is unlikely that water will enter through the casement, there is a risk that water will pool at the foot of the rooflight where the frame and lead meet. The rooflight frame must not be submerged for long periods and it is vital that the pitch of the roof allows a suitable run off. We do not recommend installtion below 17 degrees but should you choose to install our product below this pitch, please ensure that you consult your roofing contractor prior to installation. We do offer a range of rooflights for flat roof installation.
