Gutter is the narrow trough or channel that runs around the perimeter of the roof. The purpose of the gutter is to collect and channel away any water that runs off the roof. Gutters are very important as they prevent water damage to the building’s foundations, protect your exterior surfaces, and stop water from entering the home. Gutters can also lead to your rainwater tank, storing water for later use in the home or garden.
Roof is the top covering of a building, including all materials and constructions necessary to support it on the walls of the building or on uprights; it provides protection against rain, snow, sunlight, extremes of temperature, and wind. A roof is part of the building envelope.
