How Long Do Roofs and Roof Repairs Last?

Typical lifespans by material

• Asphalt shingles: commonly around 15 to 30 years, depending on the type of shingle, installation and ventilation. Architectural shingles generally last longer than basic 3-tab shingles.
• Metal roofing: often 40 years or more when properly installed and maintained.

These are general ranges. Your roof’s actual life depends on your home and your weather.

How Indiana weather wears a roof down

• Hail and wind in spring knock granules loose and lift shingles.
• Summer heat and sun dry out and age shingles, especially with poor attic ventilation.
• Freeze and thaw cycles and ice dams in winter push water where it should not go.

How long does a roof repair last?

A well-done repair on a roof that is otherwise in good shape can last as long as the rest of the roof. A repair on a roof that is worn out everywhere is buying time, and that is worth knowing before you spend the money. Ask your roofer which situation you are in.

How to make a roof last longer

• Keep gutters clean so water drains off the roof edge.
• Make sure the attic is well ventilated and insulated.
• Fix small problems, like a loose shingle or failed flashing, quickly.
• Have the roof checked after major storms.
