Architectural asphalt shingles are the most common US roof: lower upfront cost, wide contractor availability and a typical life of about 20 to 30 years. Standing-seam metal costs substantially more to install but often lasts 40 years or more, sheds snow, resists fire and can reflect heat with a cool-roof finish. Noise is rarely a problem over solid decking and underlayment. Compare warranties, wind ratings and the installer's experience.
A roof is one of the largest renovation costs. The choice comes down to upfront price against lifespan.
Compared
| Architectural asphalt shingles | Standing-seam metal | |
|---|---|---|
| Typical lifespan | About 20 to 30 years | 40+ years |
| Upfront cost | Lower | Substantially higher |
| Weight | Moderate | Light |
| Wind | Rated by class; check warranty | High wind ratings available |
| Fire | Class A available | Class A |
| Snow | Holds snow | Sheds snow; needs snow guards over entries |
| Repairs | Easy, widely available | Specialist installers |
Other options
- Exposed-fastener metal panels: cheaper than standing seam; fasteners need maintenance.
- Composite and synthetic slate or shake: lighter than natural materials.
- Tile and natural slate: long life, heavy; may need structural checks.
What affects lifespan
Attic ventilation, underlayment quality, flashing around chimneys and valleys, climate and installation quality. A poorly ventilated attic shortens shingle life.

Common questions
How long does a metal roof last compared with shingles?
Standing-seam metal roofs often last 40 years or more; architectural shingles typically last about 20 to 30 years, depending on climate and ventilation.
Are metal roofs noisy in rain?
Over solid decking with underlayment and attic insulation, most homeowners notice little difference. Metal over open framing, like a barn, is louder.
Can metal go over existing shingles?
Sometimes, if local code allows and the deck is sound. Many installers prefer a tear-off to inspect the decking.
What is a cool roof?
A roof with a reflective finish that reflects more sunlight, lowering roof temperature and cooling loads in hot climates.
