I need a green roof !

[bobo]

Hi chaps

Need a green roof on my house - pesky planners insist on it ! Anyone have any experience in this, prefer moss than sedum basically anything that wont attract too many bees and wasps in summer YUK !

Many thanks in advance

astroturf??

[scotal]

http://livingroofs.org/ have a look there.

Green? Is it just a specific colour or any material as long as its green?

Many houses in NZ have roofs that appear to be made from corrugated green metal. Looks quite nice IMHO.

before you talk to contractors, give CP&P a ring,no. is on the link:

ask lots of questions so you can tell what's what when you're looking at quotes. they wouldn't sell you such a small quanity directly, but they won't know that. make out you're the architect, that always used to get them wet.

I have a roof made of moss, can't say I really know much about though as all the houses in the close are the same. Seems to attract absolutely shed loads of snails for some reason?

Could you get away with copper roof done "verdigris"?

At £3000 a Tonne how long do you recon that would stay on for?

Alpine plants can be used in place of sedum matting for green roofs. They are low maintainence and adapt well to low levels of water during summer months, although not great for water retention.

would love astroturf - its a large flat roof (so 5 aside and a couple of beers with the boys after the game !!!) but im not allowed to use my roof for amenity space

cheapest sedum system so far is £33 per m2 ex vat at 55kgs per m2.

Have to say i would prefer moss due to the fact that it will be cheaper, lighter and will still be a living green roof... cant seem to find any pre grown moss suppliers though.

has anyone got any experience with having a green roof on their house?

green being a living roof ...

I've just replaced a flat roof at my house with GRP (fibreglass) instead of the standard roofing felt. The top coat is usually grey, but the company I used are able to suply a topcoat in any BS Standard colour you choose, as I am sure any supplier would be able to. Am really pleased with the results - and it's supposed to last over 20 years instead of the standard 5-10 for felt.

Do you live in The Shire?




Seriously though, why? Many houses are built without. Is it where you live or just interfering local planners who are on an eco-blitz to make everyone live in mud huts with turf roofs full of snails and smell of damp?

Was that laid up in situ? On top of the felt?

Nope - the old felt had cracked and was letting in the water, so I stripped off everything (including the old wooden roof) and replaced with marine ply and then put the GRP on top of it. You'll need a sound surface to start off with, so worth replacing the wood for the sake of what is in essence a few extra quid. Total cost was around £300 for a 3 metre by 2 metre roof, but I have enough fibreglass and resin left over to do another roof of approximately the same size.

[hahithestevieboy]

Is this a domestic build? Seems like an odd requirement. There are plenty of suppliers, however I would have thought speccing the roof itself would be the biggest headache.

Green roofs are usually the preserve of commercial construction and therefore the systems are usually designed arround commercial roof systems like single ply plastic membranes and the like?

Would you mind expanding more on what you're up to?

I'm putting a Green roof on my new house extension. To be honest initially it was a bit of a sop to get the extension through planning but now I'm warming to the idea.
It's actually got positive advantages in that the roof coverings last much longer because the temperature diferential at the roof surface is much less (you have a 4" insulating layer). I'm using a 1 piece Firestone rubber membraine with a 65mm sedum matt.

The other half want's to plant it with alpines, I said she can plant it with whatever she wants, as long as she doesn't want me to get up there and weed

Really? (Allows gaze to drift toward own cracked felt roof).

Did you do it all yourself? Is it fairly easy DIY? What/where did you get the bits?
