You screw planks on the side, a few holes low down on sides don’t matter too much. Then you screw the top wood (baton) directly on to the side planks. This avoiding holes on flag area of roof.
What a great question. It is stilling going great. The thing I would do differently would be a bigger overhang around the edges, but that is more to do with the “roof” and not the “green”. I think the growing medium is too thin really as the sedum is doing a lot better is shaded areas, which I think would indicate too thin soil and therefore prone to drying out . But I recently built another shed and used exact same method.
Hi@@DorkyThorpy, this is great to hear. Thanks for sharing. One more question how do you feel about its performance with regard to water drainage. Does the excess water just run off the side? Or is there a means for the excess water that is soaked up by the soil to also drip out or that just stays to water the plants.
Good video.. i want to try the same, did you mix the seeds with the compost mix? Ive noticed the seeds are sold by the gram! How many grams did you buy?
This was a long time ago. I bought a small amount of seeds and mixed with dry sand, sprinkled on top of mix, and then rub in (not raked). I did do this on another roof with plug plants, they soon spread out to cover roof.
Ok, strange questions: if you use the term "garden" for what we call a lawn, then what do you call the cultivated area where you grow food on a small scale?
Lol. We also say lawn. But for vegetables we might say “vegetable patch” or “vegetable plot”. Raised beds are also a modern trendy vegetable growing area. Hope this helps.
Hi Matt, I think we lived in this house for about 5 years. It held up well while we were there. I did the same roof on my office at new house, that’s 4 years old and going strong. If I were to improve I’d be sure to leave bigger overhang, to keep wall drier.
With this roof the growing medium is very thin and the extra weight minimal. Most “span tables for joists” are way over specified. I think I used 4x2s for this one. Happy building!
Well for this one it might only be 20/kg per meter squared when sodden. And pretty much any timber will hold that unoffcially (i.e. outside of building regs / code) but yeah some "brown roofs" used extensively in london hold half a meter of soil, and that is a serious engineering consideration, with loadings of 500kg per meter squared or more.
