8. Pebble roof
Pebbles can extend the life of a flat roof. A flat roof utilises a membrane layer, which may be a tar, asphalt, bitumen, or plastic seal for weatherproofing a house. A layer of pebbles or small rocks spread over the outer membrane will protect it from cracking and peeling when exposed to the sun.
Pebbles can also function as a filter so that leaves, sticks and other debris don’t get caught in the drains, and they can provide thermal protection by absorbing and releasing heat.
