  Excellent - how many trees can I grow on my roof? Can they be retrofitted?

      I can guarantee that a Rooftop Terrace garden cuts down almost 40% to 60% heat ever reaching the ceiling. If you have enough cover with smaller plants under larger bushes/shrubs/small trees then there will be a cool breeze around the terrace, provide nesting places for small birds and animals, a pocket of nature in an otherwise concrete heat jungle.

      The problem is who can afford to maintain the Terrace garden is the bigger challenge. Constantly checking soil, composting, watering, maintenance and just time+expense is usually beyond a lot of folks.

        It would be cool to bring back for apartment buildings though

        Green roof, looks cool, usable space, and helps with cooling. Just damned expensive.

    Trees? Not many. Grasses, herbs, wildflowers, and shrubs? Tons of them. And you can pretty easily retrofit over an existing sloped roof. And the weight is no more than a tiled roof.

      Wetness could pose a problem to the structure

        Not if you use a waterproof base layer. This isn’t some theoretical thing, its tried and tested technology in common use

    Kind of

    There are eco apartments (planning idk about practice); grass on the roof and trees growing up the side

    Lakehead University Orillia was going to do this but I don’t know if they have

  You know what cools down roofs and generates electricity? Magic!

  What about Ultra white ceramic trees?

  True though this is still practical for folks who live in deserts and other treeless places

  They also dampen noise
