Velux below minimum pitch

Sam, I'm no expert but when I fitted a Velux (a bit bigger than M06) to my 15 deg tiled roof my feeling was that this was the limit, in fact I would have liked to have had a greater pitch - some of the flashing was almost horizontal. It may depend on the profile of the particular tiles used. Have you considered the Velux FRS?

 

i'm looking at a picture of frs it's up to 15 deg it shows flat roofing felt but i could'nt see any problems with lead
flashing over tiles

 

hi sam, a couple i have been doing renovations for off and on for a few years had a poor quality roof light installed every few years they had to have it repaired (botched),being told that the seals had broken down,etc,one excuse after another,the top of the range botcher advised them to silicon it closed,so they agreed .this went on for a few years,every year or so they would come and reseal the window,saying that the silicon was breaking down to the cold weather etc. when they asked me to have alook at it,about five minutes problem found,the pitch was to shallow,they to had built up the rear of the window to try to compensate for this,the problem being in the autumn the leaves were gathering behind the window,getting wet,and lodging around the tiles etc,then when it rained heavy the leaves was causing a dam at the rear ,the water would then back flow up under the felt,hence the water leaks inside the house.to solve this i ripped the lot off,green mineral roor with osb decking,its been fine for two winters,you could also form a roof light in timber and use some polycarb sheets and some self supportingbars (same as used in conservatories). hope this has helped!!!!!!!!!!!!!!!!!!!
