Your roof is one of the most expensive parts of your home to replace, so it’s worth knowing how long it should last.

Typical lifespans

• Asphalt shingles: 20 to 30 years

• Metal roofing: 40 to 70 years

• Clay or concrete tile: 50 years or more

• Flat roof membranes: 15 to 30 years

What shortens a roof’s life

Poor ventilation, clogged gutters, storm damage and skipped maintenance can cut those numbers dramatically.

How to make it last

A yearly inspection and quick repairs of small issues are the best way to reach — or beat — the expected lifespan of your roof.
