How old is your roof?

Estimate your roof’s age from the year it was installed or the year your home was built, and see where it falls in the typical lifespan for its material.

The short answer

To find your roof’s age, check your purchase documents and home inspection report, look up roofing permits, ask the previous owner or neighbors, or check the attic for shingle wrappers and labels. If none of that works, a roofing professional can estimate age from the roof’s condition.

Finding your roof’s exact install date

The calculator gives an estimate. For the actual date, the best sources are your closing documents and home inspection report, city or county permit records (some cities, like Olathe, don’t require permits for residential reroofs), the previous owner, warranty paperwork, and clues in the attic. Our guide walks through each one: where to find your roof’s install date.

Typical roof lifespans by material

Material	Typical lifespan
3-tab asphalt shingles	15–20 years
Architectural (dimensional) shingles	20–30 years
Impact-resistant (Class 4) shingles	25–30 years
Metal	40–70 years
Wood shakes	20–30 years
Concrete or clay tile	50–80 years
Slate	75–100 years

General industry ranges. Installation quality, attic ventilation, and storms all affect real-world lifespan.

Roof age questions

How can I find out how old my roof is?

Check your home purchase paperwork and inspection report, look for roofing permits with your city or county, ask the previous owner or neighbors when roofs on your street were replaced, look for receipts or warranty documents, and check the attic for shingle wrappers or manufacturer labels. A roofing professional can also estimate age from the roof’s condition.

How long does a roof last in Kansas City?

Architectural asphalt shingles — the most common roof in the area — typically last about 20 to 30 years, and 3-tab shingles about 15 to 20. Hail, wind, hot summers, and freeze-thaw cycles in the Kansas City climate can shorten that, which is why storm history matters.

Does an old roof mean I need a new one?

Not necessarily. Age is one factor; condition is what matters. Many roofs outlast their typical range with good ventilation and maintenance. A professional inspection tells you how your roof is actually doing.

Your roof’s age is half the story.

The other half is its storm history. Check the storms recorded near your address.

Checking storm history doesn’t file an insurance claim, and no roofer gets your details unless you book an inspection.
