Firrings around roof lantern

[Bluefish]

Hi 

 

I’m trying to work out the best design of the direction of fall and flow of water for this flat roof to ensure that water doesn’t sit the building side of the lantern.

 

The lantern is 5m L x 3.2m W.

 

it will have two outlets on the front side of the building.

 

Are there any design services out there that would provide a design for this stage of a roof? Would you expect the architect to provide ?

 

Thanks in advance for any guidance!

Should be in the construction drawings set from architect / AT which will show the joists in section and the firrings

A roofing supplier like Bauder would happily give you an opinion. They designed the detail of my flat roof with lots of roof windows. Contact your local area representative.
