Planning Permission - Bay Window
Discussion
Trying to get my head round what is required from Building Regs & Planning Permission to replace a leaking bay window flat roof.
We currently have a lead flat roof on our ground floor bay window, which is now split and taking in water. Speaking to a few different roofing companies, they've all suggested changing it from lead to Firestone Rubber.
Does this fall under Permitted Development as it will not alter the size of the roof?
My thinking is that Building Regs are required as the material of the roof will be changed. I'm awaiting a response from the local Building Regs office.

I doubt Building control will be interested, most people don’t even apply for it when recovering the main roof so I wouldn’t worry about a bay window. Adding some insulation would be their main requirement but it’s not always possible. I’ve got one to do soon, it’s very deep and a weird shape, I had considered rubber but think I’m going to use fibre glass, I’m not a massive fan usually as you need perfect weather, but this bay can be covered if the weather turns nasty.
Just crack on with it, as Lofty said and alittle insulation is also a good idea while it’s uncovered. Don’t be put off lead if you have the money, it’s probably one of, if not the most durable roofing materials out there.
I’m guessing the problem with your lead top is that it has been installed in one piece, with thermal movement causing it to crack. This can be overcome by installing mop stick rolls to break the roof up in to two or three sections. Be aware that not all roofers are leadworkers!

Depends on your local LA, ours are s
t hot on roof coverings at the mo. Our brickies are doing another job alongside one of mine and the BC officer pulled them on the new roof going on the connection to the extension.
Tiles and felt to tiles and breathable membrane, "that'll need our sign off" and an extra application.

^^^ That looks a decent bit of lead work. And a bizarre bit of wiring.
Not mine I must admit, just a pic grabbed off t internet.
