DIY Green Roofs

coops82_2

just came across this great site where you can find all the information you need to construct your own green roof.

Has anyone got any tips on how to construct one?

Gonna be tricky getting the mower on to mine.

If I had a flat roof I'd be concerned enough about it leaking without planting stuff on top!

Check that your structure is strong enough to support a green roof before you start any detailed plans.

My dad converted our roof about 40 years ago - he was astounded at how much heavier a green roof was in comparison to tiles/slate!

I notice that you've started an identical thread on the Greenfingered board Duplicate threads are discouraged as they lead to confusion, so I'll merge this with the other thread.

Make sure your roof can hold the weight of the plants / grasses etc and remember with water / rain it is going to be even heavier.

I would also build it with a very slight graident on it to allow for any run off.

We will be waiting for photos when you have done it.

Good luck

We did one last year to help blend in the childrens shed. Lots of info on the web, but essentially it needs to be on a slight slope, with drainage holes in the edge boards so water has somewhere to drain to. You use pond plastic for the base layer, then thin layers of grit, vermiculite and compost. Planted mine with seedling sedums and houseleeks so it only needed to be a few cm's deep so fairly light. Gets a lot of bird damage so keep having to replant things - worth the effort though.

Did you strip back the roof? I have a small outbuilding with a basic tile roof (ie battens + tiles: nothing else) which I'd like to change to a green roof. It's about 2 sqm.
