Have you ever driven into your driveway, looked to the top of your house, and thought to yourself, “I wonder when I’m going to have to replace that roof?”

Like most of us, you’ll push that question aside since, if the answer is “soon,” there’s a big expense coming your way. Most homeowners will pay $4,687 to $9,014 for a new roof.

Life Expectancy of Roof Materials

Roof life expectancy varies by materials and conditions.

  • Asphalt Shingles, 3 Tab: 15 to 18 years
  • Asphalt Shingles, Architectural: 24 to 30 years
  • Aluminum Coating: 3 to 7 years
  • Galvalume (Metal): 30 to 45 years
  • Concrete Tile: 35 to 50 years
  • EPDM Rubber: 10 to 16 years

Depending on where you live and the outdoor elements your house is exposed to, your roof may exceed its life expectancy when properly cared for.

Factors That Impact Roof Longevity

Three main factors influence how long your roof will last:

  • Roof Color: Darker roofs absorb more heat—shortening your roof's lifespan.
  • Roof Slope Angle: Higher-pitched roofs last longer.
  • Roof Surface Sun Orientation: Roofs facing direct sunlight longer tend to have shorter lifespans.

Of course, these variables don't factor in extreme weather conditions or unexpected disasters.

6 Signs You Need a New Roof

If you’re wondering if you need to replace your roof, look for these warning signs:

  1. Cracked shingles
  2. Curled edges on shingles
  3. Bald spots on shingles
  4. Aged and worn look
  5. The appearance of dark streaks or moss
  6. Seeing sunlight from your attic

If you see one or more of these warning signs, get ahead of it. Start setting aside funds, asking neighbors for roofer recommendations, and possibly requesting quotes. Being prepared takes the sting out of not-so-fun costs of homeownership.
