Flat roof options

[littlebasher 11]

So, there seems to be 3 different roofing options that people talk about these days

Fibreglass
Rubber (EPDM)
Mineral felt

So what's the best way to go for a 40m^2 flat roof? I'd have preferred to replace it entirely with a pitched roof, but due to my garages proximity to the boundary that's not an option.

I'm assuming that half of the boards will need replacing as well, thanks to the persistent leak that i can't stop no matter how many different repair liquids i put up there!

Anyone had their roof replaced recently, so i can get an idea of cost and options?

I have no idea about cost as I do it myself but I have found that good old fashioned mineral roofing felt* glued to a reasonably decent wooden roof structure with a good felt adhesive will last a good 15-20 years.

 

(*roofing felt, not shed felt as a lot of people I know use because it's cheap but will split and crack after a couple of years.)

Get back to basic . Take all boards off and replace with three quarter ply not chipboard  as i guess thats whats already on. You will then need a proffetional  flat roofer  to put mineral felt on with a big melting pot so it goes on hot / This is not a D I Y job / Take advice from the flat roofer see what he 

suggests 

You say you cant put a pitched roof on why not if building is on your property a lot of people get put of by neighbour disputes if so let your builder sort this out. We have built extentions were neighbours wouldnt let us go on there property 2 storey as well

Unfortunately the garage walls form the property line on two sides. If I went for a pitched roof, parts of it would be overhanging their land!

I dont think it matters if only the facia and gutters go on to neighbours property its up in the air. 

Lots of boundrys are created by the building themselfs  gables etc ; Even my bugalows boundry is next doors gable and his facia and sofit over hang past on to my boundry.   My property  is only 30 years old and i have all boundrys marked on original site map. Its a very easy way for builders to make a boundry next doors gable they do not bother about facias etc overhang this .

If you are worried phone planning up have a word with them

The whole roof would require stripping off and reboarding before applying a new waterproof covering.
