Same question

Wow - I'd love a roof like that. I live on Vancouver Island with lots of rain and trees so old roofs tends to look very similar to this if you leave them long enough. Can't imagine what an "average potential buyer" would think if you wanted to sell the house eventually though. I'd be tempted to stick a sign in the lawn noting that the roof in NOT rotten, but meant to look this way and has been inspected thoroughly" other wise buyers might just not be interested.

Does anyone know if this kind of roof is suited for the tropics.. I love it, and have a wooden house in need of renovation and a new roof...my concern is, will it survive the weight of rain!

Beh, A green roof would be amazing in a tropical setting! You would need to have a roof with a steep enough pitch to drain the water quickly and a deep, but light growing medium to support the plants with enough moisture, but light enough that your structure can support it. A deep green roof covered in vegetation would provide fantastic insulation. You would need an engineer to run the numbers to see if your home can support a green roof. It would also be helpful to contact local contractors who might specialize in green roofs, or see if you can find any who would be willing to talk to you who build them in areas with similar climates. Good luck! I hope it works out, it would be both beautiful and functional!

Guess I shouldn't have removed all of the moss from my roof!

Does the green roof make the woodwork below any more susceptible to insect damage?

No. There is a TPO membrane underneath the growing medium. The plants and growing medium actually extend the life of the roof by protecting it from UV rays and direct weather.
