Both types of materials need little or no maintenance, but metal roof is more long lasting. It can withstand harsh weather and it is fire retardant. It has a Class A fire rating.It is energy-efficient because they can be heat-dissipaters for the building because of its insulating properties. Metal reflects heat from the sun, and therefrom minimizes the heat gain. Composite shingles may decay over time with severe weather changes. Cheap varieties may shed grains within a few years.
Noise – one of the drawbacks of the metal roof. The sound of gentle rain benefit the roof may be pleasant to some, but disagreeable to others. They can however be controlled by installing sound-deadening barriers.
