Garage conversion

LostInOz

Hi all.

We're planning to convert a garage to a bedroom in the near future.

The garage is 21ft by 9ft approx. It currently has a flat roof, replaced two years ago with a 10 year guarantee but we're still considering changing to a pitched roof. A traditional side to side slant doesn't seem possible as the neighbours adjoining garage is around the same height, so we'd be pouring onto their flat garage roof.

So we seem to have two options, either a pitched roof front to back, which would be very long, or a roof slanted one way.

My question is does either way provide any significant benefit over the other, and what am I looking at in rough estimates for each method?

Thanks in advance.

Why do you need to change the roof?

Have you got access to the underside of the flat roof? If so, no need to change it as you can get the insulation in. Even if you cant its cheaper to rip down the plasterboard for access and then reboard

Thank you Phil and Kiran for responding.

I was mainly thinking to replace the roof now to avoid future problems such as leaks which would be more costly to repair after the garage has been turned into a bedroom. At the moment the roof is water tight but it does get puddles after heavy rains.

If you have a 10 yr guarantee, not sure what the issue is. Seems to be a costly exercise for something that may not happen.

Why not either pitch it back towards your house and have a valley gutter or go with your original option and place guttering at the eaves so you don't pour on to your neighbours roof?
