Green Roof for a Tiny Wooden House




Introduction: Green Roof for a Tiny Wooden House

I want to explain to you how we constructed a green roof on our house made out of pallets. It means this project has two strong restrictions. The first one is that it was not advisable to load the roof with much soil and material, as it's supposed to be done on a "commercial" green roof. The second one is that I did not want to spend a lot of money on it.

Step 1: Tools and Materials


- self-adhesive bituminous felt

- coconut fiber mat

- wood lathes

- substrate for planting

- soil

- screws and nails

- of course, plants... different species of sedum!

- hand saw

- hammer

- tacker with fasteners

- hot air gun

- measuring tape

- screwdriver

- tons of imagination ;)

Step 2: Waterproofing the Wooden Roof

Once the wooden roof is constructed it is necessary to cover it with a waterproof material. For that purpose I did use a self-adhesive bituminous felt. The reason I chose a self-adhesive membrane is because it's easier to install, with no special tools and skills. Only a hot air gun was used to bend and fix the felt on the edges and corners, and a tacker to fasten the membrane from the bottom part of the roof.

Step 3: Installing the Coconut Fiber Mat

The coconut fiber is a good growing media, ecological and biodegradable. Moreover, thanks to it's structure, substrate and roots will be able to penetrate easily and stay on the roof.

Once the coconut mat was placed over the waterproofing felt I fixed it with four wooden laths on the edges of the roof.

Four narrow wooden laths more were used to form a kind of terraces on the roof. This will give an additional help to soil and plants to stay on the roof despite the slope.

Step 4: Covering the Roof With Substrate

A thin layer of about 1 centimeter should be enough, mainly because I didn't want to load too much the roof. This is the result, with already a few plants already on it.

Step 5: Sedum Harvesting

The choice of the plants was easy: just look at those small plants living on the roadsides, facing low temperatures on winter and hot sun on summer, with virtually no water and set to just a little amount of soil: SEDUM

Thanks to a mobile app it was possible to identidy the four species I found around the place I live.

- sedum acre

- sedum album

- sedum sediforme

- sedum spurium

Step 6: Planting the Sedum

It probably is the most creative part of the project, this is why I decided to ask for help from creative people ;)

I hope you liked this project!!!

    Our roofs are often unused if we do not use them for purposes like solar panels and such. Thus, to utilize the space for gardening purposes that are beneficial for consumption and the environment is definitely a good alternative.

    Very nice!
    I'd like to do something like this for the roof of our shed.
    I didn't think it was possible before because I wasn't sure if the roof could support the weight of the soil, but they way yoy did it, there's not much soil required...
    I' 'm still not sure if it' s an option because the roof also functions as a water outlet for the roof of our house... but maybe I could leave a canal open for the water... I'll look into it, thanks for the inspiration!

    It makes me happy to know my project is a "source of inspiration"

    You're right... if the roof of the shed is the outlet of the water of your house... I would also think twice about doing it.

    Anyway, for the moment, our green roof drains the water kite well... too much well, in fact! because I would prefer it to keep more water. During last days I've installed an automatic watering system with an exudative hose because summer is coming.

    After a couple of weeks, sedum is getting fixed to the soil and the coconut fiber mat, and it's growing up :)

    This is so lovely! It's great that you used native sedums. They're one of my favorite succulents. :)

    I think its smashing and its exactly what I will do with the 4 dog kennels i have to build now . I just have to make sure the dogs can't mount the roof!
    I will plant food vegetables like peas and tomatoes with a trellis post front and back.

    I'm very glad to have helped you!
    If you have a look to the first picture, there is also a planter attached to the facade of the hourse with tomatoes and salads.
    Somehow we had a very similar idea ;)
