A missing shingle after a St. Louis windstorm is easy to spot. The trouble is that many roof problems begin more quietly: a lifted edge, a few loose granules, or a cracked shingle near a vent. Knowing how to inspect roof shingles gives you a better chance to address small damage before water reaches the roof deck, attic, insulation, or ceiling below.
A homeowner inspection is not a replacement for a professional roof evaluation, especially after hail, high winds, or a suspected leak. It is, however, a practical way to monitor your roof, document visible changes, and know when it is time to call for help.
Start With a Safe Ground-Level Inspection
The safest roof inspection begins with both feet on the ground. Walk around the house slowly on a clear day, ideally when the roof is dry and the sun is high enough to show uneven areas. Use binoculars or your phone camera zoom to get a closer look without climbing a ladder.
Look at the roof from several angles. A shingle roof should generally appear flat, consistent, and well-covered. One area may receive more sun or weather exposure than another, so some variation is normal. What you are watching for is a noticeable change in shape, color, or texture.
Pay close attention to roof edges, ridgelines, valleys, chimneys, skylights, vents, and the area around satellite mounts or other penetrations. These are common locations for damage because they manage water flow or are more exposed to wind.
From the ground, watch for these visible warning signs:
- Shingles that are missing, torn, cracked, curled, buckled, or lifting at the edges
- Dark patches, bare spots, or a mottled appearance that may indicate granule loss
- Sagging roof sections, uneven lines, or soft-looking areas
- Damaged flashing around chimneys, vents, skylights, or wall intersections
- Shingle pieces, roofing nails, or excessive granules collecting around the home
A few loose granules are common on a newer roof and after installation. Large amounts that resemble coarse black sand, especially after a storm, deserve a closer look. Asphalt granules protect shingles from ultraviolet exposure and help slow weathering. When they come off in significant amounts, the shingles can age faster.
Check Gutters and Downspouts for Clues
Your gutter system can reveal roof wear that is not obvious from the yard. If it is safe to access the gutter from a stable ladder, look inside for granule buildup, shingle fragments, or debris that is blocking water flow. Never lean a ladder against the gutter itself, and do not inspect alone if conditions are wet, windy, or unstable.
Granules in the gutters do not automatically mean you need a roof replacement. Shingles shed some granules as they age, and a heavy rain can move accumulated material into the downspouts. The concern is a sudden increase, especially when it accompanies bald-looking shingles, cracking, or leaks.
Also check whether gutters are overflowing, pulling away from the fascia, or holding standing water. A roofing issue and a drainage issue can work together. Water that backs up at the roof edge can contribute to damaged shingles, rotted fascia, and leaks near the eaves.
Look Inside the Attic Before You Climb Anything
Many homeowners focus only on the roof surface, but the attic can provide the clearest evidence that water is getting through. Choose a dry day and bring a flashlight. Walk only on framing or established flooring, never on exposed insulation or the drywall ceiling below.
Look for water stains on the underside of the roof deck, damp insulation, mold-like growth, rusty nails, or active drips. A musty smell can also point to lingering moisture. Note the location of any staining, but remember that water can travel along rafters or decking before it becomes visible. The stain may not sit directly beneath the roof damage.
Daylight coming through the roof deck is another reason to schedule a professional inspection promptly. Small openings around penetrations may be repairable, while widespread moisture or sagging decking can indicate a larger project. The earlier the cause is identified, the more options you usually have.
When to Get on the Roof – and When Not To
For most homeowners, a ground-level and attic inspection is enough. Walking on shingles creates real risks: falls, broken shingles, voided warranties in some situations, and accidental damage to weak roof decking. Steep roofs, high roofs, wet roofs, roofs with visible damage, and roofs in extreme summer heat should be left to trained professionals.
If you have safe access to a low-slope section and are experienced using a ladder, keep the inspection brief. Wear shoes with good grip, avoid stepping on ridge caps or edges, and never work near power lines. Do not walk on a roof alone. If the shingles feel soft, springy, loose, or unusually hot, get off the roof.
At close range, inspect shingles for cracked tabs, exposed fiberglass matting, popped nails, broken seal strips, and edges that have lifted in the wind. Check flashing for rust, gaps, bent sections, or dried-out sealant. Caulk can fail over time, but adding more sealant is not always the right repair. It can hide a problem while trapping water or directing it somewhere else.
Inspect After Wind, Hail, and Heavy Rain
Missouri weather can put a roof through several seasons in a single week. After a strong storm, inspect as soon as conditions are safe. Start in the yard, where wind-blown shingles, metal flashing, branches, and granules often show up first.
Wind damage can lift shingles without tearing them completely off. Once the seal is broken, the shingle may be more likely to lift again in the next storm. Hail damage can be harder to identify from the ground. It may leave bruised areas, knocked-off granules, or small impact marks that require trained evaluation to distinguish from normal wear.
Do not assume a roof is fine because no water is dripping indoors. Storm damage can compromise a shingle system before a leak appears. Take date-stamped photos of visible debris, damaged shingles, gutter buildup, and interior stains. This documentation can be useful if a repair or insurance claim becomes necessary.
Know the Difference Between Wear and Urgent Damage
Roofs age gradually, and not every imperfection calls for immediate replacement. Minor discoloration, small amounts of granule loss, and a single damaged shingle may be manageable with a targeted repair. The right answer depends on the roof’s age, shingle condition, ventilation, previous repairs, and whether matching materials are available.
Call a roofing professional soon if you see missing shingles, exposed underlayment, active leaks, sagging, widespread cracking, repeated granule loss, or damaged flashing. A leak around a chimney or vent may be a localized flashing repair. A roof with damage across multiple slopes may need a broader solution. A clear inspection helps separate those situations instead of guessing.
Build Roof Checks Into Your Home Maintenance
Inspect your roof at least twice a year, usually in spring and fall, plus after significant storms. Spring checks can reveal winter damage and drainage problems. Fall checks help you clear leaves and address issues before freeze-thaw cycles and snow add more stress.
Keep nearby tree limbs trimmed back, maintain clean gutters, and make a simple record of repairs and inspections. If you notice a new stain or damaged area, photograph it from the same location over time. That makes changes easier to track and gives a roofing contractor useful context.
Roofing & Exterior PROS provides clear, no-pressure inspections for homeowners who would rather have a trained local team assess the details. You should never have to gamble on whether a small roof issue can wait. A timely inspection can protect your home, your budget, and your peace of mind before the next round of weather moves in.
