Reply to comment by Hour-Watch8988 in Planting more trees could axe summer deaths by a third. Modelling of 93 European cities finds that increasing tree cover up to 30% can help lower the temperature of urban environments by an average of 0.4°C and prevent one in three heat deaths as a result. by MistWeaver80

Yeah the whole point of a roof is to keep the elements away from the house. Adding tons of soils and vegetation and watering it everyday is just asking for trouble, specially if you cheaped out on the installation.

Most green roofs don't require tons of soil and watering vegetation. They're usually pretty thin layers of media and root barriers for grasses and other native plants to live, they're called extensive green roofs.

Intensive green roofs usually don't cover the whole thing, and have deeper layers and larger plants. They're much less common.

The intensive ones are awesome to see, but not practical. Thd extensive ones won't have near the impact on local temperature of trees.

It might not be better than painting all the roofs white for heat but they'd still do better than shingles or solar panels. A combination of that for the roofs and trees, especially native where possible, would not just impact local temps but also fauna.

I hate going up on to my roof too. So many things could go wrong with a setup like that. Screw that noise. I want a low maintenance roof.
