Roof ideas

[theboss]

Hello gents
Had my oven up and running for over 2 years now and considering a roof as autumn approaches.
I was going to use a sheet of transparent corrugated plastic so it’s as least offensive to the eye as possible.

Has anyone used corrugated before?
I’m unsure how to deal with the flue?
My plan is to have the roof sitting just under the cowl that way I can leave a 10mm gap between the flue and the hole cut, this will prevent any water running down the inside of the flue as the coal should catch it first.

But it won’t stopwater running into the hole from the upper side of the roof, where the “v”s meet the hole. Even if I sealed the 10mm gap with Envirograf, it would still leave a ponding issue? ?

Has anyone got any suggestions

Thanks in advance

Do you have an insulated chimney?
If you do then you just cut out a hole and seal it with standard flash band.
If you do not then you might have to be more resourceful.
I have no idea what temperature your chimney pipe will be where it meets the plastic or even what size your chimney is ?

As above. You need a double-walled flue for starters.  Almost regardless of length your chimney will be hot enough to melt your new roof. You need to insulate it from the plastic and take it up as high as possible above it also. 

To make life easier I’d avoid corrugated and go for flat sheeting. Still not ideal but easier to seal properly. 

To be honest I’d avoid clear roofing at all. Might look nice and unobtrusive on day 1 but give it a while and it will be dirty, yellowed, scratched and covered with bird cr@p. More money but a proper roof will be much nicer, even if proper means felted rather than tiled. You can always add clear sections in plastic sheet  or velux windows dependent on budget.
