Alternatives to Sarnafil roof covering

[str]

Planning an extension and the planning officer has made a condition of the consent that we use Sarnafil for a flat roof in dark grey or equivalent.

Can anyone recommend an alternaitve product? I do like the look of Sarnafil but have been advised that it can be expensive, albeit no suggestions of alternaives where forthcoming from this source?

thanks

We use Rhepanol fk as manufactured by FDT which has an insurance backed guarantee of 15 years but a certified life expectancy in excess of 30 years but there are a few others around such as Sika Trocal or Rubberbond.

In my experience, Sarnafil usually works out the cheapest of all the single ply membrane systems (mainly commercial though to be fair), it may also be a problem getting a contractor to do a small domestic roof. The planning officer sounds like a knob, print off some slick images of EDPM and see if he'll approve that instead.

she has been a bit of a tw@t - this is one of 6 or so conditions, including being specific on the colour of the window and door frames

sorry for my ignorance - EDPM?

Try flaguk.co.uk they do a lead grey colour same as Sarnafil in a TPO or a PVC it goes down the same as Sarnafil, looks the same but works out cheaper comes with 15 or 20 year guarantee we use it all the time.

Sorry, typo, should've bin EPDM http://www.rubberbond.co.uk/index.php
To be fair, colour of windows is quite a common one.

Confused as to why they are insisting you use a certain product? I can understand colour, but Sarna is not exactly going to have listing status, is it.

Personally, i'd delve deeper.

I think the planning officer pick sarnafil as a product as this is perhaps the only one she knows to give the appearance she was suggesting we should have - the extension is to the rear of a stone house, c. 1900's, and is relatively modern in appearance - lots of glass, flat roof, galvanised steel water goods, etc - so she had suggested this would be in keeping with the modern theme!

To be fair, she did say "or similar" in reference to sarnafil

As far as i am aware, she cannot dictate type, only colour. So any grey/charcoal membrane then.

Have a look at Alwitra.

You forgot to mention single ply is crap.

You forgot to mention single ply is rubbish.

Because?

Hi Xenon
Tell me more, I know it sometimes gets used on roofs it shouldn't be used on and I know there are some very bad products and installers out there. But there are some good ones and good roofers to.
What happened to you?

We're Sarna/Alwitra etc approved installers. Commercial, not domestic. Its cost in relation to its performance is a rip off. Blistering/puncturing/windlift (despite Sarna writing the specs) are a pain. We started a 16000 m2 project on Brent X in the 90's, the client stopped it after the first area due to problems, and changed it to Felt.

Vapour barriers are dire, sealing up is a nightmare.
