Asphalt is familiar and widely installed
Architectural asphalt shingles are common, repairs are familiar to many roofers, and upfront cost is typically lower than many metal systems.
Metal changes material and labor
Standing-seam and other metal systems can provide long service life and a distinct appearance, but fabrication, flashing, penetrations, snow movement, and specialized labor can raise the project cost.
Roof geometry matters
Simple roof planes are easier for most systems. Valleys, dormers, skylights, chimneys, and wall transitions increase detailing requirements regardless of material.
Compare exact systems, not category names
For asphalt, compare shingle line, underlayment, ventilation, flashing, and warranty. For metal, compare panel type, thickness, finish, fastening system, trim, and underlayment.
