How long does a roof last? The InterNACHI life expectancy chart lists 3-tab asphalt shingles at 20 years, architectural shingles at 30, metal at 40 to 80, and slate at 60 to 150 years (InterNACHI). In the Kansas City metro, treat those numbers as the most you should expect, not a promise. Hail, wind, summer heat and freeze-thaw winters all wear a roof down faster. Below we cover lifespan by material, what shortens it, the signs a roof is near the end, and how to decide between repair and replacement.
Key takeaways
- Asphalt shingles are typically rated at 20 to 30 years. InterNACHI puts 3-tab at 20 and architectural at 30, and NAHB's 2007 study put asphalt at about 20.
- Metal, slate and tile last much longer. InterNACHI lists metal at 40 to 80 years, slate at 60 to 150, and clay or concrete tile at 100 or more.
- A "lifetime" shingle warranty does not tell you how long the roof will last. GAF and Owens Corning define "lifetime" by how long the original owner owns the home, and the coverage is limited to manufacturing defects.
- Kansas City weather takes years off a roof. IBHS found that weathered shingles hit by repeated small hail became up to ten times more likely to be damaged by later large hail.
- After a storm, take photos from the ground, make only temporary repairs until the insurer inspects, and on the Kansas side, confirm the roofer is registered with the Kansas Attorney General.
What roof life expectancy is (and what it is not)
Roof life expectancy is the number of years a roof covering usually keeps water out under normal conditions before it needs replacing. It is an average. Your roof can beat it or fall short of it.
The two charts most people cite come from home inspectors and home builders. In the summer of 2006, NAHB conducted a telephone survey of manufacturers, trade associations and researchers to estimate how long home components last (NAHB study). The study says life expectancy depends on the quality of installation, the level of maintenance, weather and climate conditions, and the intensity of use (NRCA library listing). InterNACHI keeps a similar chart and warns that it should be used only as a general guideline and not as a guarantee or warranty (InterNACHI).
Here is what life expectancy is not:
- It is not a warranty. A warranty is a contract with conditions and exclusions. We explain the difference below.
- It is not a countdown. A 12-year-old roof hit by a bad hailstorm can be finished. A 25-year-old roof with good ventilation and no storm damage may still be sound.
- It is not the same everywhere. Climate changes the number a lot. InterNACHI's separate Florida chart lists 3-tab asphalt shingles at 10 to 12 years and architectural at 15 to 20, far below its national figures.
So use the charts to plan your budget. To decide what to do with your own roof, have someone inspect it.
How long each roofing material lasts
This table puts the two main sources side by side. Where NAHB did not list a material, we say so.
| Roof covering | InterNACHI estimate | NAHB 2007 estimate | Notes for KC homeowners |
|---|---|---|---|
| Asphalt, 3-tab | 20 years | About 20 years (asphalt shingles) | Thinner. Older KC homes often have it. |
| Asphalt, architectural (laminated) | 30 years | Not listed separately | Most common on newer homes. |
| Metal | 40 to 80 years | Not listed | See our metal roofing page. |
| Copper | 70+ years | Over 50 years | Rare on homes. Usually used for accents. |
| Slate | 60 to 150 years | Over 50 years | Heavy. Needs a crew with slate experience. |
| Clay or concrete tile | 100+ years | Over 50 years | Heavy. Check whether the framing can carry it. |
| Wood shakes or shingles | 25 years | About 30 years | Needs more upkeep. |
| Fiber cement shingles | 25 years | About 25 years | Not common. |
| Simulated slate | 10 to 35 years | Not listed | Products vary widely. |
| EPDM rubber (low-slope) | 15 to 25 years | Not listed | Porches, additions, flat sections. |
| TPO (low-slope) | 7 to 20 years | Not listed | Wide range. |
| Modified bitumen (low-slope) | 20 years | Not listed here | Common on low-slope residential sections. |
| Built-up roofing (BUR) | 30 years | Not listed | Mostly commercial. |

Asphalt shingles
Most homes in the metro have asphalt shingles, so this is the number most people want. Owens Corning says properly installed, high-quality asphalt shingles can provide two to three decades of protection (Owens Corning). Architectural shingles are thicker and carry the higher rating on InterNACHI's chart. In Kansas City, expect storms and heat to shorten that range.
Metal, slate and tile
These materials can outlast the people who install them. The limit is usually the rest of the roof: flashing, underlayment, fasteners and the deck. A metal roof can also stay watertight after hail and still show dents. Some insurance policies treat dents like that differently from damage that causes leaks, so read your policy.
Low-slope sections
Many KC homes have a flat or low-slope section over a porch, garage or addition. Those membranes have their own, often shorter, lifespans. When you budget, plan for them separately from the main roof.
Why warranty years are not lifespan
This is a common point of confusion. A shingle labeled "lifetime" is not rated to last forever. The word has a legal meaning in the warranty document.
- GAF says "Lifetime" means as long as you, the original owner(s), own the property where the shingles are installed, and the Lifetime warranty is applicable only to shingles installed on a single-family detached residence owned by individuals (GAF warranty).
- After GAF's early full-coverage period ends, any remedy will be reduced to reflect the use you have had from the roof, and for a Lifetime warranty under GAF's System Plus warranty, GAF's contribution in years 51 and beyond is 20% (GAF System Plus sample). Under GAF's standard Shingle and Accessory warranty, that 20% level starts in year 41 (GAF).
- Owens Corning says its Duration limited lifetime warranty covers manufacturing defects for as long as the owner of a single-family detached home owns it (Owens Corning). Its warranty does not cover non-Owens Corning roofing components, such as flashing, fasteners, pipe boots, and wood decking (Owens Corning warranty document).
| Question | Life expectancy | Manufacturer warranty |
|---|---|---|
| What it measures | Typical years of service | What the manufacturer will pay for, and when |
| What it covers | The whole roof covering in normal use | Manufacturing defects in the products listed, under the stated conditions |
| Storm damage | Hail and wind shorten it | Hail is generally an insurance matter, not a defect claim. Read your warranty to be sure. |
| How it changes over time | Wears down gradually | Full coverage for an early period, then reduced (prorated) coverage |
| Who it applies to | Any owner | Often the original owner, with limited transfer rules |
Workmanship, meaning installation mistakes, is a separate question. Ask every bidder in writing what installation warranty they provide.
What shortens a roof's life in Kansas City
InterNACHI notes that roofs in areas that experience severe weather, such as hail, tornadoes and/or hurricanes, may also experience a shorter-than-normal lifespan (InterNACHI). That describes Kansas City.
Hail, including small hail
The Greater Kansas City area averages about 40 to 60 thunderstorm days per year, and the National Weather Service counts a storm as severe when it produces large hail, winds of 58 mph or higher, or tornadoes (Prepare Metro KC). As recently as this month, the National Weather Service warned of quarter-sized hail and winds of up to 80 mph across the metro (KCUR). Statewide in Kansas, there were 82,498 total reported storm claims in 2025, and insurers paid out $879,074,368.54 on homeowners and auto policies (Kansas Insurance Department).
Big hail is not the only problem. IBHS research found that sub-severe hail knocks away protective granules from asphalt shingles, exposing the underlying asphalt to sunlight and weathering. Shingles that were weathered and hit by two rounds of simulated small hail became up to ten times more susceptible to damage from later large hail impacts compared to new shingles (IBHS). Separate IBHS testing shows natural short-term weathering can measurably reduce hail impact performance, even on impact-resistant products (IBHS). Our KC hail and storm damage guide covers this in more depth.
Wind and aging sealant
A September 2026 IBHS study found that while many shingles get more wind-resistant in their first few years, most begin to decline between years five and 10. It also found that unsealing of shingles remains the single greatest driver of wind vulnerability (IBHS). Lifted or creased tabs after a windstorm are worth a closer look.
Summer heat
InterNACHI says plainly that hot climates drastically reduce asphalt shingle life (InterNACHI). A hot attic adds to the heat coming from above. That is why ventilation matters so much here.
Freeze-thaw and ice dams
Ice dams form when heat leaking into the attic melts snow on the roof and the water refreezes at the cold eaves. According to the Department of Energy's Building America Solution Center, ice dam formation requires snow on the roof, a poorly air sealed and/or poorly insulated attic, and freezing temperatures, and ice dams can form with as little as 2 inches of snow accumulation (PNNL / DOE). Its recommended fixes are to air seal the ceiling, insulate the attic and ventilate the roof.
Installation, ventilation and the deck
Some problems that shorten a roof's life are easy to miss. One example is a ridge vent installed without working soffit intake. A setup like that cannot move air through the attic. Another is old plank decking on older houses, which may need to be covered with new decking before modern shingles go on. Ask your roofer about both. Problems like these are hidden under the shingles, so they rarely show up in a quote written from the driveway. See our roof replacement page for more.
What helps a roof reach its rated life
- Look at it every year. Check from the ground with binoculars and from the attic with a flashlight. You do not need to climb up.
- Get a professional check after hail or high wind. Damage from small hail is easy to miss from the yard. See roof inspection.
- Keep gutters and valleys clear so water drains off instead of backing up at the edges.
- Fix ventilation and attic air leaks to help with both summer heat and winter ice dams.
- Repair small problems early. A cracked pipe boot or loose flashing is a repair job. Left alone, it can turn into a rotted deck.
- Keep records. Save dated photos, invoices and warranty papers. They help with warranty claims, insurance claims and selling the house.
Signs your roof is near the end
No single sign proves you need a new roof. When you see several of these together, get an inspection:
- Shingles that are curling, cupping, cracked or missing in more than one area
- Heavy granule buildup in gutters on a roof that is past its first couple of years
- Bare or shiny spots where the granules are gone
- Stains on ceilings or attic sheathing, or leaks that come back after repairs
- Daylight through the roof boards, or a spongy feel or visible sag in the roof line
- Rusted, lifted or missing flashing around chimneys, vents and walls
- A roof at or past the age range for its material in the table above
What to do after a hailstorm
- Stay off the roof. Wet or damaged roofs are dangerous. Look from the ground.
- Take photos first. Missouri's insurance regulator says to document it and take photos before making any temporary repairs (Missouri DCI). Photograph dented gutters, vents, siding and window screens too.
- Prevent more damage. Tarp an opening if needed and keep the receipts. Kansas regulators say you may be reimbursed for the expenses associated with temporary repairs (Kansas Insurance Department).
- Hold off on permanent work. The same Kansas checklist warns that if you make permanent repairs before the insurance company inspects the damage, your claim may be denied.
- Contact your insurer promptly and write down your claim number and the names of everyone you talk to.
- Get your own inspection. Have a roofer check every slope. The side of the house facing the storm can be damaged while the other side is fine.
- Be there for the adjuster. Kansas guidance says to be present when the adjuster inspects your property.
Repair or replace: a decision table
We will not give you a percentage rule. We have not found a primary source for one, and every roof is different. Use this table to frame the conversation with your roofer instead.
| Situation | Usually points toward | Why |
|---|---|---|
| Young roof, a few shingles missing after wind | Repair | The rest of the roof still has plenty of life left. |
| One leak at a pipe boot, chimney or wall | Repair | Flashing and boots wear out before shingles do. |
| Hail bruising on several slopes | Inspection, then possibly an insurance claim and replacement | Damage spread across the roof is hard to fix with patches. |
| Roof at or past its material's age range, with widespread granule loss | Replace | Repairs only buy a little time on a worn-out surface. |
| Leaks keep coming back in different places | Replace, or inspect the deck | The problem may be in the deck, the underlayment or the ventilation. |
| Sagging, or a soft deck underfoot | Replace with deck repair | The structure under the shingles is failing. |
| Ice dams every winter | Fix the attic first | A new roof will not stop ice dams caused by attic heat loss. |
Insurance basics in Missouri and Kansas
Check your policy before storm season. According to Missouri DCI, most standard homeowners policies cover damage caused by fire, lightning, wind and hail. It also warns that your policy deductible can change at renewal, and there can be separate deductibles for different types of loss (Missouri DCI). The Kansas Insurance Department reminds homeowners that a home may be insured for replacement cost or actual cash value. Ask your agent which one applies to your roof and what it means once the roof gets older. In Kansas, an insurance company has 30 days to complete an investigation of your claim, and if it isn't finished in 30 days, it must provide a reasonable explanation (KDI checklist).
Check the roofer before the roof
A roof lasts longer when it is installed right, so the contractor matters. On the Kansas side, every roofing contractor must obtain a roofing contractor registration certificate from the Kansas Attorney General to legally do roofing work for a fee, a rule in effect since July 1, 2013 (Kansas AG). The Attorney General says the registration is in addition to any other local requirements that may be imposed by cities or counties (Kansas AG). Missouri has no comparable statewide roofer registry, so local licensing matters more there. Our Kansas vs Missouri licensing guide and licenses and permits page explain the differences. For a full checklist, see how to hire a roofer in Kansas City.
How we put this together
We read widely read articles on this question in October 2026, including articles from an insurer, a restoration company and a home insurance site. We listed what each one covered and what it left out. Then we checked every number against primary sources: the InterNACHI life expectancy charts, the NAHB 2007 component study, GAF and Owens Corning warranty documents, IBHS research, Kansas City storm data, the Kansas Attorney General, and the insurance regulators in both states. We did not test any roofing products, and none of this guide is based on our own inspections. Where we could not find a reliable source, such as a percentage rule for repair versus replacement or local prices, we left it out.

FAQ
How long does an asphalt shingle roof last in Kansas City?
InterNACHI's chart lists 3-tab asphalt shingles at 20 years and architectural shingles at 30 years, and NAHB's 2007 study put asphalt at about 20 years. Those figures assume normal conditions. InterNACHI also notes that roofs in places with hail and other severe weather may not last as long, so a Kansas City roof may need replacing before it reaches the chart number.
How long does a metal roof last?
InterNACHI lists metal roofing at 40 to 80 years and copper at 70 years or more. The actual number depends on the metal, the coating, the installation and how much hail and wind the roof takes.
What is the difference between a roof warranty and a roof's lifespan?
A warranty is a contract covering manufacturing defects under set conditions. A lifespan is how long the roof actually keeps water out. GAF and Owens Corning both define a 'lifetime' warranty by how long the original owner owns the home, and coverage gets smaller (prorated) after an early full-coverage period.
How do I know if hail shortened my roof's life?
Look from the ground for dented gutters, downspouts and vents, and check your gutters for loose shingle granules. A roofer can check each slope up close for bruised or cracked shingles. IBHS research found that even repeated small hail knocks granules off and speeds up aging, so damage is not always easy to see.
How often should I have my roof inspected?
We suggest at least one look every year from the ground and from the attic, and a professional inspection after any storm with hail or high wind. Once your roof gets close to the age range for its material, an inspection every year is a good habit.
What does a roofer need to work legally in Kansas?
Under the Kansas Roofing Registration Act, a roofing contractor generally needs a registration certificate from the Kansas Attorney General before doing residential or commercial roofing work for a fee. Cities and counties can add their own requirements on top of that. You can look up a roofer in the Attorney General's online registry.
What does homeowners insurance cover on an old roof?
The Missouri Department of Commerce and Insurance says most standard homeowners policies cover damage from fire, lightning, wind and hail. What you get paid depends on your policy, your deductible and whether your roof is insured at replacement cost or actual cash value. Ask your agent before storm season, not after.
Get two or three roofers to look at it
The age of your roof tells you when to start paying attention. An inspection tells you what to do next. Our directory lists Kansas City metro roofers alphabetically, with no ratings and no paid placements. On the Kansas side, each listing shows the roofer's registry standing, checked against public records. If a contractor covers your area, our request form sends your project to that one contractor, and you see their name before you share your details. For a second or third opinion, call other roofers straight from the directory. Start with your ZIP code and request a roofing estimate.
