The lifespan of roofing sheets depends on the material, coating quality, installation method, and surrounding weather conditions.

Standard GI sheets may have a shorter life in highly humid or corrosive environments if not properly maintained.

Colour coated and galvalume sheets generally offer better durability because of improved protective layers and finish.

Stone coated steel roofing is known for long service life when installed correctly and maintained periodically.

Regular inspection, cleaning, and timely repair of scratches or loose fasteners can significantly increase roofing sheet life.
