Flat Roof Nightmare - Help someone Please!

Maz

Hello everybody, I hope someone can give me some advice/guidance.

I have an extension at the back of my house with a flat roof. Recently, I noticed that water was seeping through one of the halogens in the bathroom, so I got a builder in that I know to have a look. He says the flat roof is knackered and needs re boarding and re felting. He said it could be patched but would only be a short term solution and the cost of replacing the boards, felt etc would be in the region of £600. Roof measures approx 2.8mx3.5m.

Is this a fair price d'yer reckon?

could you not have it fibreglassed?
we were due to have ours done last year but due to other building work going on i put them off till this april.
our balcony is approx 21 ft by 21 ft and its costing us 700 with new 22mm boarding

Are you sure a slate/roof tile has not damaged your flat roof in the gales we have had;)

I have been reading this with interest. I have just accepted a quote to have my flat roof which is leaking 20ft x 20ft - reboarded, 6inch fibreglass added to insulate, packed to give me a fall so that the water drains away and refelted for 1700 pounds. is that expensive????????

Builder never mentioned fibreglassing. I'm in total ignorance of flat roofs so am at the mercy of builders advice etc! Going by your price, it would possibly work out a lot cheaper that way.

it is suposed to be pretty easy to DIY but we just havent got the time and besides its not much more for us to have it done by this company we found.
they have great refs and we have seen the work they have done

I would reckon £600 would be a fair price for the job myself.
This would be for a board and felt job.
A fibreglass roof is a different thing ...its one piece job no felt etc. This tends to be quite a lot more expensive but I would say it would probably last longer.

FIBREGLASSING....this means that when they take the old felt and board off they will fill the void between the roof and ceiling with fibreglass insulation.
I think this guy is doing what you might call a 'proper job'.
Get the job done asap cos if more water leaaks in the ceiling might come down underneath and then that will cost even more.

The fibreglass is for the insulation, to reduce the heat loss through your cieling.

Off now to repair someone's roof (burrr)8 roof tiles and lead flashings, on a Sunday too.
Keep my regular customers happy.

Its got nothing to do with that

fibreglass roof isnt the pink stuff you use for insulation in this case
its a roof covering that is used instead of the old fashioned felt and hot pot
its is more economical and has a longer life span.

no - I am actually having a 6 inch fibre glass insulation to retain the heat and then re-board and re-felt.

this is the proper way to do it.

I know what a fibreglass roof is, the poster was talking about insulation, which should be fitted under building regs.
