It’s a simple, step-by-step list to help you or a professional inspect your roof. The goal? Catch problems early before they turn into pricey nightmares.

What’s in a Roof Inspection Checklist, Anyway?

here’s more to a roof than just the part you see from the street. A good roofing checklist looks at the outside and the inside. You’ve got to check the surface, the structure, and even the attic. It’s not rocket science, but it’s definitely more than a quick glance.

Roof surface (shingles, metal panels, etc.)
Flashing (those metal strips around chimneys, vents, etc.)
Gutters and drainage
Attic condition
Signs of leaks, mold, or water damage
Structural sagging
Chimney and skylight condition

Each part tells a story about your roof’s health. If something’s wrong, it’ll whisper—or sometimes shout—at you from one of these spots.

Residential Roof Inspection Checklist: Don’t Let Your Home’s Hat Slip Off

When it comes to your house, your roof is kind of a big deal. If it goes bad, so does everything underneath. A residential roof inspection is about making sure your cozy living space doesn’t turn into a water park.

What to Look for on a Residential Roof:

Missing or damaged shingles: If your roof looks like it had a rough night, it probably did. Shingles should lie flat. If they’re curled, cracked, or gone, rain is sneaking in.
Granules in gutters: Asphalt shingles shed over time. If you see roof confetti in your gutters, it’s a sign the shingles are aging fast.
Flashing: This metal stuff is your roof’s duct tape around vents and chimneys. If it’s rusted or loose, leaks are coming your way.
Sagging spots: Your roof should look as straight as your grandma’s ironing board. Any dip means trouble.
Attic check: Take a peek inside. Do you see stains, mold, or daylight where it shouldn’t be? That’s a big red flag.

Bonus Tip:

Walk around your house with binoculars. It sounds silly, but you’ll see a lot without climbing anything. Plus, your neighbors will either admire your caution or assume you’ve taken up bird watching

Commercial Roof Inspection Checklist: Bigger Roof, Bigger Problems

Commercial roofs are like the adult version of residential roofs. More serious, more expensive, and often flat. But that doesn’t mean they’re high-maintenance unless you ignore them.

What to Check on a Commercial Roof:

Ponding water: Flat roofs shouldn’t hold puddles. Water just sitting there means drainage is bad. That leads to leaks, mold, and eventually angry tenants or employees.
Blistering or bubbling: This isn’t a pizza. Bubbles mean trapped moisture or air under the surface. Not a good sign.
Roof membrane damage: That rubbery-looking stuff? It needs to be smooth and sealed. Any tears or cracks can open the floodgates—literally.
Drainage systems: Are the scuppers, downspouts, and gutters clogged? One bird’s nest can mess up everything.
HVAC units: Most commercial roofs host AC units. Make sure the area around them is dry and solid. Water pooling around these can damage the roof and the equipment.

From a friend who owns a strip mall: “One blocked drain cost me a weekend and a roofing crew. Now, I pay a guy to walk the roof once a month with a checklist. Cheaper than replacing the whole roof.

Metal Roof Inspection Checklist: Tough, But Not Invincible

Metal roofs are known for their long life and low maintenance, but even Superman has kryptonite. Corrosion, loose panels, and fasteners can creep up on you.

Keep an Eye On:

Rust spots: A little orange on a silver roof isn’t festive. It’s a sign of corrosion, and if you catch it early, it’s easy to treat.
Loose screws or fasteners: Over time, screws back out because of temperature changes. Tighten or replace them if they look suspicious.
Seam gaps: Panels shift over time. Gaps between them can lead to leaks.
Dents and dings: Hail and falling branches love metal roofs. While they don’t always cause leaks, they can weaken the surface.
Sealant condition: The stuff used to close gaps and joints can dry out and crack. Make sure it’s flexible and intact.

Flat Roof Inspection Checklist: Pancakes Are Great, Flat Roofs—Tricky

Flat roofs are like teenagers they look cool but need constant supervision. Since water doesn’t slide off easily, problems can stack up.

Watch for These Troublemakers:

Pooling water: Even a little puddle is a big deal on a flat roof.
Membrane wear: If it looks thin, cracked, or like it’s trying to escape replace it.
Vegetation: Moss and grass don’t belong up there. It means moisture is staying too long.
Flashing and edges: Flat roofs often fail around the edges. Look for lifted corners or peeling seals.
Drain clogs: Birds, leaves, trash—anything can clog a drain. A blocked drain is like a ticking time bomb.

Neighbor’s tale: A friend had a flat roof that started leaking because of pine needles. Yep, pine needles. Clean your drains.
