Hi. What flashing kit should I order for the Velux GGLMk04 when installed on a pitched roof using Cedar shingles please?


Hi Simon 

you would need the EDW flashing and you would have to remove some of the insulation off the back of the flashing in order to get it to sit correctly 


what is the flashing code for slate?



For slate you would need product code EDL MK04 0000.

If doing a recessed Slate installation you would need EDN MK04 0000.


What flashing is required for a 78cm x 98cm Velux rooflight? The roof is large concrete tiles.


For a large concrete interlocking or profiled tile you would need the below EDW Flashing kit.
