How much does a metal roof cost?
Cost depends on roof size, pitch, access, tear-off needs, deck repairs, valleys, dormers, chimneys, penetrations, flashing details, profile, and color. Interlock aluminum roofing is a premium permanent system and generally costs more initially than asphalt shingles.
Can metal roofing go over shingles?
Sometimes, but not automatically. Existing layers, deck condition, local requirements, ventilation, and manufacturer instructions determine whether removal is appropriate.
Will a metal roof be noisy?
On a residential assembly with decking, underlayment, insulation, and ceilings, rain noise is very different from an open agricultural building.
Will it rust or attract lightning?
Aluminum does not rust, and metal roofing does not attract lightning. Building location, height, and surrounding terrain are more relevant to lightning exposure.
How long will it last?
Service life depends on material, coating, design, installation quality, environment, and maintenance. Review written warranties rather than relying on a verbal promise.
