Flat roof.....any advice/tips appreciated

[Radcliffe0212]

Our house has a flat roof, bitumen on board, 80 sq.mt. Our intention is to insulate using Celotex EL3000 and cover with a modern rubber system (Rubberbond).

Celotex comes in a range of thicknesses, what thickness would be recommended to insulate effectively?

How would you best attach a timber retaining lip for the insulation slabs.

Any advice on the project would be appreciated, I plan to do the prep myself and then have an approved contractor lay the rubber.

Let the roofer do all the work, otherwise if there is a problem in the future there might be an 'issue' with the guarantee.

I laid a rubber roof system last year on my flat roof, is was so easy to be amost laughable at some of the quotes the pro's gave me... between £1600 & £2000 for the material and labour.

I paid £350 for the rubber, glue and trim from these guys http://www.rubba-seal.co.uk/home and did it myself in about 4 hours, saved me a fortune and it really is easy as long as you follow the instructions.

If this was my garage or flat roof extension I wouldn't think twice about it, but it is the main house roof with some fiddly bits around a number of chimneys and a front facade and a total area of 80 sq metres.

hi,
according to me the celotex of the thickness of 60mm will work definitely, and rest the roofers will suggest you the best.
