Agreed, It'll very likely last longer than the felt roof.

Hi Guys, How do you work out the timber frame size for a polycarb roof? I'm going to have one down the side of my house. What do you need to work it out? Because I can post details if needed? Cheers Zeberdee

Thanks for the reply.

Anybody?? Mwroofline??

Ply or OSB to be honest. Lead will be expensive, EPDM Rubber wont be. EPDM Will be in 1 single strip, No joins etc.

Any Pics?

Your best bet is to get the ''valley''/Water Run-Off'' done in EPDM. It's Rubber that can be done in 1 sheet, Ideal for what your after TBH. 1 Single sheet all the way. NO JOINS! NO LEAKING POINT!!

Firestorm? Its Firestone mate. Firestone is prob the best EPDM rubber to use for ya flat roof!!

Hi, I've not worked with Sarnafil myself, But from the look of the pics you've posted, The joins/overlaps have come ''unstuck'' Surely it's common sense to lap the joints the other way?? So the water flows over the joints and not into the joints????

Hi, When decking a flat roof or overboarding ready for a new membrane do people tape the joints?? If so what tape is used? The membrane that was going to be used it EPDM?, I'm just a bit worried that where the boards meet and there is a joint then the EPDM may come unstuck.

It sounds like a Friday verge to me lol!! A house 6 years old? And its crumbling already?!! :shock: (what house builder was it again?) Just get the DRY VERGE SYSTEM fitted for a small cost, Once done it'll never have to be done again in the homes lifetime. SIMPLES!!

Rip it down and re-build it, Get the job done properly 1st time!! If you've had quotes and not 1 has mentioned a re-build then I'd worry about the 'roofer'!! Maybe they'll change a few bricks and repoint the stack and everything will be ok :roll:

Hi MW Roofline! Why do you use that way to join the roofs? What effect does it have? Cheers Tony.

3.2x3.2? That is about 10-12 sq mts? That would be done in ONE piece of rubber, However the rubber that would be needed is probably near to 15-20 sq mts to include upstands and the gutter drip etc. If you already have plyboard decking and its sound, Why rip it up and replace it? Why not...

Depends if your after a total replacement or capping. Capping, £500-£1000, Depend who you get to do it IMO!! Replacement £800-£1500, Once again, Depend who you get to do it. IMO!!

Hi, Just a quick question for the roofers out the who use the red propane bottles. Is it ok to transport a propane bottle in the boot of a car lying down?? It'll have to be lying down because the bottle is too big to be stud up. It'll only be lying down for an hour or so. Cheers

None of them, Go EPDM.....Never worry about it again once fitted.

Where can you get these rubber collars? Do they fit around the soil pipe right against the wall? The ones coming out of the flat roof, about 2-3" from the wall? Cheers Zeb

Cheers for the reply. Nah, Nothing to do with cheapness, Just that a mate has had a flat roof to strip, Which is felted, And this stuff is the decking. How do you fix (if you can?) some OSB/Ply boards onto it if not being able to find the joists? And is it ok to totally remove it?
