    How do we call the layer that looks like a roof of the rainforest?

    We can call the layer an overstory, a canopy, a crown canopy or a crown cover.

    Canopy - The uppermost layer in a forest, formed by the crowns of the trees

    Overstory - The uppermost layer of foliage that forms a forest canopy.

    Crown canopy/crown cover - the cover formed by the leafy upper branches of the trees in a forest.

    Layers of rainforests from top to bottom:

    Emergent layer of a few tallest trees (emergents) - they do not form a roof

    Overstory or Canopy layer - the primary layer of the forest and forms a roof over the two remaining layers.

    Understory layer

    Forest floor layer

    Therefore "emergent layer" in Answer 002 below is not at all the roof top layer of a rainforest, but rather like a small number of chimney structures on the roof.

    TOMING88 is making a joke again with an incredible "waterproof canopy" in the answer.
