Where metal shines
- Long service life with proper underlayment and trim
- Snow slide — less ice dam weight at the eave on steep pitches
- Fire and impact resistance (hail ratings vary by profile)
- Good for south-facing slopes that bake asphalt shingles
Where asphalt still wins
- Lower upfront cost on typical ranch and colonial footprints
- Easier color and profile match in established neighborhoods
- Simpler partial repairs if only one slope is damaged
- Familiar look for resale in many NH suburbs
NH-specific details either way
Ice & water membrane at eaves, valleys, and penetrations matters on both systems.
Metal needs careful attic ventilation and snow retention planning above entries and driveways.
We quote both when it fits the home — with written specs, not a verbal "about the same price."
