Sun Tunnel:

A Sun Tunnel is a skylight that captures natural sunlight at the roof and carries it through a tubular shaft to the interior of a home.

Waterproofing is the process of coating a roof with a substance that will provide a watertight seal, and prevent future leaks and damage from weathering.
