47 questions Kansas City homeowners actually ask, answered by a licensed Johnson County roofing contractor. No sales pitch, including when the honest answer is that you do not need us yet.
What a roof costs
Real numbers for the Kansas City metro, and where the money actually goes.
Is $25,000 a lot for a new roof?
For a typical Johnson County house, yes, $25,000 is above average. The average asphalt shingle replacement in Overland Park runs about $18,700 for a 2,900 square foot roof, or roughly $6.34 per square foot. A $25,000 quote is normal for a large home, a steep roof, premium materials, or a house that needs significant decking replaced.
Ask any contractor quoting near $25,000 to show you which of those four factors is driving it. If none of them apply, get a second estimate.
What is the most expensive part of replacing a roof?
Labor. On most residential replacements labor is about 40 percent of the total, ahead of materials at roughly 34 percent. Tear-off and disposal add about 12 percent, deck repairs about 8 percent, and permits plus overhead the rest.
This is why the cheapest bid usually signals a smaller or less experienced crew rather than a better deal on shingles. Material prices barely move between reputable contractors.
What is the cheapest time of year to get a new roof?
Late fall through February. In the Kansas City metro, demand for crews collapses after storm season ends, so scheduling is easier and contractors have more room to work with you on timing. Shingle prices themselves are set by manufacturers and do not drop seasonally.
Asphalt shingles need roughly 40 degrees to seal properly, so a good roofer hand-seals in cold weather rather than pretending the temperature does not matter.
Can you negotiate the price of a new roof?
Yes, but the productive version is negotiating scope, not squeezing the number. Ask what changes if you move from premium to architectural shingles, whether gutters are included, and how deck replacement is billed. Contractors who will drop thousands off a quote on the spot were overpriced to begin with.
On an insurance claim there is far less room. The insurer sets the scope, and Kansas law prohibits a contractor from covering any part of your deductible.
Do roofers overcharge?
Some do, and the pattern is recognizable. Watch for a price that drops sharply the moment you hesitate, a quote with no line items, pressure to sign the day of the inspection, or a bid far outside the $6 to $9 per square foot range typical here.
Three written, itemized estimates make overcharging obvious. The outlier is usually the problem, in either direction.
How many estimates should you get for a roof replacement?
Three. That is enough to see the real market range without stalling the project. Make sure each one lists the same scope, because a bid that excludes tear-off or deck repair will always look cheaper until the invoice arrives.
How to pay for a roof when you can't afford it?
Four routes are common: insurance if the damage is storm related, contractor financing, a home equity line, or phasing the work by repairing the failing slope now and replacing later. A reputable roofer will tell you honestly whether a repair can safely buy you a season or two.
A small discount for cash or check is normal because it avoids card processing fees. What is not normal is a demand for full payment in cash up front. Legitimate contractors take a deposit, then bill the balance on completion, and they give you a written contract either way.
Cash-only with no paperwork is one of the clearest storm chaser signals.
What is the best roof for your money?
Architectural asphalt shingles, for almost every home in this metro. They run about $4 to $6 per square foot installed, carry 110 to 130 mph wind ratings, and last 25 to 30 years in real Kansas weather. The upgrade from 3-tab to architectural buys far more protection than the upgrade from architectural to premium.
How long does it take to replace a roof on a 2000 square foot house?
One to two days for a straightforward asphalt replacement. Add a day for steep pitches, multiple layers to tear off, or significant deck damage found once the old shingles come off. Weather is the usual reason a job stretches longer.
Kansas gives homeowners a verification tool most states do not. Use it.
How to tell if a roofer is lying?
Ask for their Kansas Attorney General roofing registration number and verify it yourself. Every roofer working in Kansas must be registered, and the state publishes a searchable directory showing whether a company is In Good Standing. A roofer who cannot produce a number, or whose number does not check out, has already answered the question.
Then ask for photos of the specific damage on your roof. Someone inventing damage will describe it generally. Someone who was actually up there will show you a slope, a course and a bruise.
The reliable signals are structural, not stylistic: no Kansas AG registration, no local city or county license, a certificate of insurance they will not have their agent send directly, no physical local address, pressure to sign before you have read the contract, and a request for large cash payment up front.
Kansas has required roofing registration since 2013, and working unregistered carries civil penalties of up to $10,000 per violation. Unregistered is not a technicality.
How to spot a rogue roofer or storm chaser?
They appear within days of a hailstorm, knock doors across a whole neighborhood, use an out of state phone number or a magnetic truck sign, offer to handle everything with your insurer, and want a signed agreement immediately. Verify the Kansas registration and ask where their shop is. Both questions end most of these conversations.
What are some signs a roofer is reputable?
Current Kansas AG registration in good standing, the correct city or county license for your address, insurance certificates sent by their agent rather than forwarded by a salesperson, a written itemized scope, a manufacturer certification, a workmanship warranty in writing, and a track record you can verify with local addresses.
What to watch out for in a roofing contract?
Check that it names the exact shingle line and color, states the underlayment and ice and water shield coverage, spells out how deck replacement is priced per sheet, sets a payment schedule tied to milestones, and states the workmanship warranty length. Watch for open-ended clauses letting the contractor bill unlimited extras.
Also confirm who pulls the permit. In Johnson County that is the contractor's job, and a roofer trying to hand it to you is avoiding inspection.
Should I accept a free roof inspection?
From an established local company, yes. A free inspection is a normal way for roofers to earn work. The thing to be careful about is who you let on your roof. An unregistered crew has an incentive to find damage that is not there, and can cause damage while looking.
Ask for the written report and photos regardless of whether you hire them.
From the ground, look for uneven shingle courses, exposed nail heads, missing or reused flashing at the chimney and walls, no drip edge along the eaves, and debris or nails left in the yard. From the attic, look for daylight at the deck seams and for staining after the first hard rain.
There is no official ranking, and any company claiming the title is marketing. Nationally the largest residential roofing contractors by revenue are firms like Erie Home and Power Home Remodeling, but size does not predict quality on your house. What predicts it is state registration, local licensing, real references nearby, and a written warranty.
How to find the best roofers?
Start with the Kansas AG roofing directory to build a shortlist of registered companies, cross-check local reviews with addresses in your area, then ask each for three references within a few miles. Local track record matters more than national brand recognition, because you need them to still be here when the warranty is tested.
Code, layers and permits
The rules Johnson County inspectors actually enforce.
What is the 25% rule for roofing?
It comes from Section R908.3 of the International Residential Code. No more than 25 percent of a roof covering may be removed and replaced in any 12 month period unless the entire roof is replaced and brought up to current code. Cross that threshold and a spot repair becomes a full replacement.
The window is rolling, not per storm. Two separate repairs in the same year add together.
Is it okay to have three layers of shingles on a roof?
No. Code caps you at two layers. Under IRC R908.3.1.1 a roof recover is prohibited where two or more layers already exist, so a third layer requires a complete tear-off first. A contractor offering to go over two existing layers is proposing work an inspector can fail.
Weight is the reason. Each layer adds roughly 250 pounds per square, and most residential framing was never designed for three.
Can I reroof over existing shingles?
Only if there is exactly one existing layer, the deck underneath is sound, and the existing shingles are lying flat. Even then it is usually a false economy. You cannot inspect the deck, you cannot install ice and water shield properly, and the new shingles run hotter and fail sooner.
For most homes with rafters 24 inches on center, 5/8 inch is the practical standard, with 1/2 inch acceptable at 16 inch spacing. Half inch over 24 inch spacing sags between rafters over time. Match whatever is already there so the new deck sits flush with the old.
How many bundles of shingles does it take to do a 20x20 roof?
A 20 by 20 plane is 400 square feet, which is 4 squares, and architectural shingles run 3 bundles per square, so 12 bundles. Add about 10 percent for waste, cuts and starter, which puts you near 14 bundles. A pitched roof has more surface area than its footprint, so measure the slope, not the floor.
What is the first rule of roofing?
Water flows downhill, and every layer has to shed onto the one below it. Nearly every leak traces back to that rule being broken somewhere: flashing lapped the wrong way, underlayment run uphill, or a fastener driven through a water path.
Does Missouri require roofing contractors to be registered?
Yes, since January 1, 2023. Missouri Senate Bill 326 requires every roofing contractor operating in the state to register with the Missouri Department of Commerce and Insurance, with proof of at least $1,000,000 in general liability coverage and a current workers compensation policy. So both sides of the Kansas City metro require registration, just through different agencies.
Kansas registers roofers through the Attorney General, Missouri through the Department of Commerce and Insurance. A contractor working both sides of the state line needs both, and some cities such as Independence, MO add their own class-based licensing on top.
Do I need a permit to replace a roof in Johnson County?
Yes. Roof replacement requires a permit, and roofing contractors must hold a Johnson County contractor license. Overland Park, Olathe, Lenexa and several other cities run their own licensing and permitting programs, so the requirement depends on your address rather than the county alone.
State registration with the Attorney General is separate from, and does not replace, local licensing.
How long roofs actually last
Warranty years and real years are not the same number.
Does a 30 year roof really last 30 years?
Usually not in Kansas. A 30 year architectural shingle typically delivers 22 to 27 years here. The rating comes from manufacturer testing under ideal conditions, and it assumes proper attic ventilation. Hail, 100 degree summers and freeze-thaw cycling all pull the real number down.
How long does a 25 year shingle really last?
About 18 to 22 years in this climate, assuming the attic is properly vented and the roof has not taken a serious hail hit. Poor ventilation is the single biggest reason shingles fall short of their rating, because attic heat cooks them from underneath.
Is there really a 50-year shingle?
The shingle exists, but the expectation does not. Products sold as 50 year or lifetime carry prorated warranties that cover materials only, and coverage drops sharply after the first 10 to 15 years. In Kansas hail, a 50 year shingle is realistically a 30 year shingle with a nicer warranty document.
Is a 20 year old roof too old?
Not automatically, but it is at the point where the decision belongs on your calendar. A well ventilated 20 year old architectural roof with intact seal strips can have several years left. The bigger issue is insurance: many carriers move roofs past 15 to 20 years onto actual cash value, which changes what a future claim pays.
Are old shingles still good?
Check three things: whether granule loss has exposed the black mat, whether the seal strips still hold the tabs down in wind, and whether the shingles are brittle enough to crack when lifted. If any of the three fail, the roof is past repair territory regardless of its age on paper.
What roof color lasts the longest?
Lighter colors hold up marginally better because they run cooler and fade less visibly, but the difference is small compared with ventilation and shingle quality. Color affects how obvious the aging looks more than how fast it happens.
What color roof increases home value?
Neutral mid-tones do best in the Kansas City market: weathered wood, driftwood, charcoal and slate grays. They suit the brick and siding combinations common across Johnson County and appeal to the widest set of buyers. Strong colors like blue or green narrow your buyer pool.
What color roof makes a house look bigger?
Lighter, cooler tones. A light gray or weathered wood roof recedes visually and makes the roofline read as less dominant, which makes the house appear larger. Very dark roofs visually cap the house and make it look lower and heavier.
What roof shingles to stay away from?
Avoid 3-tab shingles on any home in this metro. Their wind ratings top out around 60 to 70 mph, and straight-line winds here regularly exceed that. Also avoid discontinued or off-brand product a contractor happens to have in stock, because warranty claims and future color matching both become impossible.
Insurance and storm claims
What changes with roof age, and how the money actually arrives.
How old may a roof be before insurance claims it's too old?
There is no universal cutoff, but most carriers writing in Kansas shift roofs to actual cash value somewhere between 15 and 20 years, and some decline replacement cost coverage entirely past 20. Actual cash value means depreciation is deducted permanently rather than reimbursed after the work is done.
Check your declarations page for the words replacement cost or actual cash value on the roof surfacing line. That single phrase can be worth thousands on a claim.
What not to say to a roof insurance adjuster?
Do not guess at the age of the damage, do not speculate that the roof was already worn out, do not accept a verbal scope on the spot, and do not say the damage is old if you do not know. Stick to what you observed and when. Let the documentation and your contractor's measurements carry the argument.
You are allowed to have your roofer present during the adjuster's inspection, and it usually helps.
What is the most common roof damage?
In the Kansas City metro, hail. The 2026 season set records here, with 244 severe thunderstorm and tornado warnings issued through late April alone. Wind damage to ridge caps and field shingles is second, and failed flashing around chimneys and vents is the most common source of leaks unrelated to storms.
In two parts. The insurer first pays actual cash value, which is the replacement cost minus depreciation and minus your deductible. After the work is finished and invoiced, the withheld depreciation is released as a second check. On an actual cash value policy, that second check never comes.
Kansas law prohibits any contractor from paying, waiving or rebating your deductible. An offer to do so is a reason to walk away.
The practical questions people are slightly embarrassed to ask.
Can you stay in your house while the roof is being replaced?
Yes, and most people do. It is loud, roughly like continuous hammering directly overhead, and vibration can shake dust loose from ceilings. Plan around naps and calls. Homes with anyone sensitive to noise, and pets in particular, often do better somewhere else for the day.
How messy is a roof replacement?
Messy during, clean after, if the crew is doing it right. Tear-off throws granules, old nails and shingle fragments across the yard and landscaping. A proper crew tarps the perimeter, keeps a dump trailer at the driveway, and runs a magnetic roller over the whole property before leaving.
Move cars out of the driveway, and take fragile items off walls that share framing with the roof.
Am I supposed to let roofers use my bathroom?
You are not obligated to. Professional crews on residential jobs plan for it and generally do not ask. If a crew will be on site for multiple days, some homeowners offer, and it is a courtesy rather than an expectation either way.
Do roofers expect a tip?
No. Tipping is not expected in roofing and no reputable crew will act differently without one. If the crew did excellent work and you want to acknowledge it, cold drinks on a hot day and an honest online review are worth more to them than cash, and the review is worth more to the company than either.
What to ask for when getting a new roof?
Ask for the shingle line and color in writing, synthetic underlayment rather than felt, ice and water shield at the eaves and in the valleys, new flashing rather than reused, a ridge vent if the attic ventilation is inadequate, full nail cleanup, and the workmanship warranty length stated on the contract.
Who is responsible when something goes wrong on your roof.
Can a roofer sue me if he falls off my roof?
If you hired a properly insured contractor, their workers compensation coverage handles their injured employees and you are generally protected. The exposure appears when you hire an uninsured crew, because an injured worker with no coverage may pursue your homeowners policy instead.
This is the practical reason to have the certificate of insurance sent directly by their agent. It is not paperwork for its own sake.
How many roofers fall off a roof?
Roofing is consistently among the most dangerous occupations in the United States, with falls the leading cause of death in construction. That statistic is the argument against homeowners climbing up for their own inspections, especially on a wet or steep roof.
