Is a metal roof cheaper in the long run?

It can be if you keep the house through a second asphalt replacement cycle. If you expect to sell in five years, asphalt usually has the better payback unless buyers in your market pay a clear premium for metal.

Can metal go over existing shingles?

Sometimes, if the deck is sound, the extra weight is allowed, and the manufacturer warrants an overlay. Many quality jobs still tear off so flashing and ventilation can be done correctly.

Asphalt Shingles vs Metal Roof: Cost, Lifespan & Which to Choose

Asphalt is the U.S. default: lower upfront cost, easier repairs. Metal costs more to install and lasts decades longer. Climate, HOA rules, and how long you will stay in the house decide the better buy.

Upfront cost vs lifetime cost

Asphalt usually wins the bid. Metal often wins if you stay long enough to skip a second reroof. A metal roof that lasts 50 years can replace two asphalt roofs on the same house.

Architectural asphalt: commonly $400–$700 per square installed
Standing-seam metal: commonly $800–$1,400 per square installed
Factor dump fees, flashing, and ventilation into both bids

Climate and performance

Hot, sunny regions benefit from cool-color metal or high-reflectance shingles. Coastal salt air is hard on cheap fasteners. Heavy snow sheds well on metal with the right snow guards.

Hail: look at impact ratings on both systems, not marketing photos
Wind: metal panels need specified clips and edge details
Noise: a proper underlayment and deck make rain on metal far quieter than people expect

HOA, resale, and look

Some associations restrict metal profiles or colors. Architectural shingles remain the safest resale look in many suburbs. Standing seam reads as a premium upgrade when the neighborhood already has mixed materials.

Ask for a color board in sun, not only a showroom sample
Check whether solar mounting is easier on your chosen system
