The penguins at Edinburgh zoo have a green roof in their new enclosure.

The roof provides a viewing area for visitors and lets them get close enough to watch the zoo’s 130 king penguins, gentoos and macaronis breed and nest.

Richard Millar, technical manager at parent company Icopal, said: “Garden roofs not only look much more pleasant but they take in the rain and spread out the water or use it to grow. The lawns are drought tolerant and don’t need much watering.”
