Hi Roger how would you form the fall for the water to run off from the topside of a roof lantern with the firring pieces please any idea will be welcome.
Thanks for your message. Our EasyClean coating means that more rainfall helps to clean the glass. The rainwater rinses away most of the dust and debris helping it to look cleaner for longer. Many thanks, Michael
Well very nice looking Lantern good pitch on the glass ,not sure why it’s being siliconed down onto bare wood,the roof covering should always be done first and go up and over the kerb edge .just means someone has to remove it all that good work ,and yes the kerb should always have 50mm kingspan fitted then use foil back plaster board
Would the plasterboard sit flush against the insulation on the inside of the up-stand? Would you need to apply a vapour control barrier to the inside of the upstand?
Hi Tom, you can see some examples of our Slimline lantern completed here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JuXCViltqxU.html. Many thanks.
As Roger mentioned, it depends on the project but sometimes it's more convenient for the tradesperson to fit the rooflight while waiting on other trades. The roof covering can be installed afterwards and brought up into the rooflight and under the drip-lip to finish it.
I’m currently planning something similar with a roof light etc .. I’m just a little concerned about any water collecting on/around the face of the kerb nearest and parallel to the house. Obviously the fall will take rain water away from the rear elevation of the house but is it a common issue for rain water collecting where it hits the kerb? Is it something to be concerned of? or is it as long as the roof is properly sealed then it’s nothing to worry about? Thanks and great video!
Hi Jonathan, you can get around this by falling the roof in two directions. This is mentioned at the start of our video with Skill Builder so that the water flows diagonally around the rooflight and off the roof. They do this for the same reason as water will collect between the rooflight and the property. If you still have concerns we do also have wall abutment flat rooflights that negate this issue. Many thanks, Michael
Thanks for the comment. For our rooflights you flash over the frame of the lantern as well, which is classed as part of the minimum 150mm required, so you do not have to build the timber upstand 150mm high. Many thanks.
Hi there, Thanks for commenting. As Roger says, the Lantern itself sits absolutely level on the upstand. There is a mitred fall on the flat roof to aid rainfall. Thanks.
don't need a fall on the kerb for a roof lantern....don't know why they have done that...rooflight has a pitch built in....just need a fall for flat rooflights....duhhh !!!!
