✓A top hail metroA hazard mapping firm ranked Kansas City, Kansas, eighth among hail-prone metros in the US. On March 10, 2026, hail up to baseball size fell in parts of the metro. Hail damage often does not leak right away.insurancejournal.com
✓Soft insulation, more damageA study of roofs after a hail storm found roofs over soft insulation took major damage far more often than roofs over a hard cover board. Crushed insulation can start leaking months after the storm.continuingeducation.bnpmedia.com
✓Freezing nights all winterNormal January lows in Kansas City sit near 19 to 21 degrees, and highs near 38 to 40, the National Weather Service says. Water in small cracks freezes at night and thaws by day. By spring, small cracks may have grown.weather.gov
✓Hot summer roofsNormal July highs in Kansas City reach about 89 degrees, and roofs get much hotter than the air. Heat dries out sealants, caulk and the washers under metal roof screws.weather.gov
✓Tornado and windOn May 4, 2003, an F4 tornado crossed Wyandotte County into Missouri. Tornadoes are rare, but strong storm winds are common. Wind lifts loose edges first.en.wikipedia.org
Most roof problems show up inside first
Facility managers rarely spot roof trouble on the roof. They spot it on the ceiling, on the floor, or in a call from a tenant. These are the signs people in the Kansas City metro call about most. Some need help today. Most mean you should book an inspection before the next storm.
See any of these? Call (913) 347-6527 or send the form. We call you back and set up an inspection the same day. We connect you with one independent local roofing contractor. They inspect the roof and give you a written report and price.
Call the same day
These signs mean water is getting in now, or something could fail:
Water dripping inside, onto the floor, stock, desks or equipment.
Ceiling tiles that sag, bulge or fall.
Water near electrical panels, lights or equipment.
A roof deck that sags or feels soft.
A large section of roof that peeled back or blew off in the wind.
Move people and stock away from the water. Keep staff off the roof during a storm.
Book an inspection soon
Inside the building
Ceiling stains that grow, darken, or come back after a new tile.
Musty smells in top-floor rooms or near the ceiling.
Rust or drip marks on the underside of a metal deck.
Peeling paint or damp spots high on walls, mostly near the roof edge.
Higher cooling bills in summer with no other cause. That can mean wet insulation.
From the ground
Dented gutters, downspouts and metal trim after a storm. The roof likely took hail too.
Water spilling over gutters in a normal rain.
Loose or bent metal at the roof edge.
Stains or streaks running down the outside walls.
Plants or moss growing at the roof edge or in gutters.
On the roof, for the crew to check
Water still sitting days after rain.
Seams that have split or lifted.
Bubbles and blisters in the roof surface.
Cracks, holes or bruised spots.
Flashing pulled away from walls, curbs and units.
Clogged drains full of leaves, gravel or trash.
Shrinking rubber that pulls away from the edges.
Rust, loose screws or missing washers on metal roofs.
Why a dented gutter matters
Hail, freezing nights, summer heat and wind all show up in the local facts above. The key point is timing. Hail damage often does not leak until months later. So a dented gutter is a good reason to check the roof now.
Signs that can usually wait
Not everything is urgent. These are often fine to note and check at the next routine visit:
A dry, old stain that has not changed in years, with a known past repair above it.
Light chalking or fading on a white roof.
A small puddle that is gone within a day after rain.
Small surface scuffs with no cracks.
Not sure? An inspection settles it.
Repair or replace
One sign alone rarely means you need a new roof. The inspector looks at the whole picture:
How old is the roof?
How many spots leak?
How much of the insulation is wet?
Has it been patched many times?
If most of the roof is dry and sound, a repair or coating may be the right call. If large areas of insulation are wet, a new roof may cost less over time. The cost guide has typical ranges.
Keep the next sign small
Trade groups say to inspect flat roofs twice a year and after big storms. A maintenance plan puts that on a schedule. Then you find small problems before your tenants do.
Frequently asked questions
How do I know if my roof has hail damage?
From the ground, you often cannot tell. Look at gutters, downspouts, metal trim and the fins on rooftop units. Those show hail dents first. Hail can bruise a roof or crush insulation without leaving a hole you can see. An inspection after any big storm is the safest way to know.
Is standing water on a flat roof normal?
A little water right after rain is normal. Water still there days later is not. It means a drain is clogged, the roof has sagged, or water has nowhere to go. Standing water wears the surface faster and finds every weak seam.
My ceiling stain is old. Does it still matter?
Yes. A stain means water got through at some point. If it grows, darkens, or comes back after a new tile, the leak is still active. Even if it is dry now, the insulation above may still be wet.
Can I check the roof myself?
Roofing trade groups say people without training and safety gear should not walk on roofs. You can safely look for signs from inside and from the ground. Leave the roof walk to a trained crew.
How old is too old for a commercial roof?
Published guides put TPO at about 20 to 30 years and metal at 40 years or more. Is your roof near those ages and leaking in more than one spot? Then it is time for an inspection and a straight answer.
Do I need to act right away?
Active leaks, sagging ceilings and water near electrical gear need a call the same day. Most other signs mean book an inspection soon, before the next storm season.
