Lesgrandepotato Posted Monday at 09:22 Share Posted Monday at 09:22 I’m starting to plan out a workshop and office build along side our house. Our build is in an amphitheater with a stream / water fall running through. Everything goes mossy sooner or later so I’m thinking about embracing that… So I’m trying to get my head round the construction detail for a green roof, we won’t bring in flora and fauna. We’ve got enough of that already. My main thought concern at the moment is around the additional weight and drainage. I’d expect we’d cover the roof i ln gravel and a light soil. Drainage off the side into the beck below. Link to comment Share on other sites More sharing options...
SteamyTea Posted Monday at 10:34 Share Posted Monday at 10:34 The extra loads are easy enough to work out, then it is just a case of finding the right size beams and rafters to take those loads. What a structural engineer does all the time. Link to comment Share on other sites More sharing options...
ToughButterCup Posted Monday at 11:27 Share Posted Monday at 11:27 Welcome back. Went for a walk at the back of your place recently. To celebrate my new hips. Our flat roof was going to be a green roof. The more we looked at the issue the higher the costs went. Until we covered our eyes with our hands and dared peek at the numbers no longer. We are surrounded by eco roofs (leisure center - university is full of them ) My God they can look tatty after a while. Anyway. Nice to see you both back. ( That garage used for your car yet? 😜) 1 Link to comment Share on other sites More sharing options...

Yes, you need to weed it and remove dead things, and infill dead areas. The loading from wet moss isn't significant, unless with gravel , but it is from turf which will develop. The roof membrane is a different spec to resist roots, but I recall that it is not UV proof so there is a lap. I did a calculation once to prove to planners that a green roof was not the optimum for sustainability. The effect of the load on the steel building added tons of steel and concrete. Plus it kept water back from the rainwater harvester. And then there is safety and access. Link to comment Share on other sites More sharing options...

I do need to update you kiddies on my micro hydro scheme as well. We gonna start making electric! 1 Link to comment Share on other sites More sharing options...
