A roof problem rarely starts with water dripping into the middle of the kitchen. More often, it begins with a lifted shingle after a St. Louis windstorm, a small stain on a ceiling, or granules collecting near a downspout. This free roof inspection checklist helps homeowners catch visible warning signs early, document what they find, and make a clear decision about whether it is time to call a professional.
You do not need to climb onto your roof to do a useful inspection. In fact, walking on a roof can be dangerous and may cause additional damage, especially on older shingles, steep slopes, or wet surfaces. A careful ground-level review, a look from an upper window, and an attic check can reveal plenty.
Start With Safety and the Right Timing
Choose a dry day with good daylight. Do not inspect during rain, high winds, lightning, or immediately after a storm when surfaces may still be slick. Bring your phone or camera so you can take clear photos of any concern, including wide shots that show the location and close-ups that show the damage.
A pair of binoculars can help you inspect roof slopes without using a ladder. If you do use a ladder to look at gutters or roof edges, keep it on level ground, have someone nearby, and do not step onto the roof. For commercial properties, have maintenance staff document observations from safe access points and keep records with the building file.
It is smart to perform a visual inspection twice a year, usually in spring and fall, plus after hail, high winds, or a branch impact. Missouri weather puts roofs through rapid temperature swings, heavy rain, ice, and strong storms. Regular checks give you a baseline, making new damage easier to spot.
Your Free Roof Inspection Checklist
Work around the property slowly. Start from the street, then inspect each side of the home or building. You are looking for changes, missing materials, and signs that water is not moving where it should.
- Check for missing, cracked, curled, or lifted shingles. Missing tabs, uneven shingle lines, exposed nail heads, and curled edges can allow wind-driven rain beneath the roofing system. A few damaged shingles may be repairable. Widespread wear across several slopes can point to an aging roof that needs a more thorough evaluation.
- Look for loose or damaged flashing. Flashing is the metal material installed around chimneys, skylights, vents, walls, and roof valleys. It is one of the most common leak points because it manages water where roof surfaces meet. Watch for bent metal, gaps, rust, cracked sealant, or flashing that appears to be pulling away.
- Inspect the roofline for sagging. A straight roofline is generally a good sign. A dip, bow, or low area may indicate trapped moisture, damaged decking, framing concerns, or structural movement. This is not a wait-and-see issue. Have a roofing professional inspect it promptly.
- Check valleys and low-slope areas for debris. Leaves, sticks, and shingle granules can collect where water naturally travels. Debris holds moisture against roofing materials and may block drainage. On low-slope residential sections and commercial roofs, standing water after a storm deserves attention, particularly if it remains more than a day or two.
- Look for granules at downspouts and along the driveway. Asphalt shingles shed some granules over time, especially when new. Heavy or sudden granule loss, however, can signal hail damage, advanced wear, or shingles nearing the end of their service life. Granules protect shingles from UV exposure, so their loss matters.
- Inspect gutters and downspouts. Gutters should be securely fastened, pitched correctly, and free of major dents, separations, and overflowing debris. Water spilling behind a gutter can damage fascia, soffit, siding, and the roof edge. Make sure downspouts direct water away from the foundation.
- Check fascia, soffit, and siding near the roofline. Peeling paint, soft wood, stains, blistering, or warped trim can point to ongoing moisture exposure. These details often reveal roof or gutter issues before the leak becomes visible indoors.
- Examine chimneys, vents, skylights, and pipe boots. Rubber pipe boots can crack from sun exposure. Skylight seals can fail with age. Chimney masonry may show loose mortar or staining. These components need to work together with the roof system, not separately.
- Look for storm damage around the property. Broken tree limbs, damaged fencing, dented metal vents, torn window screens, or hail marks on soft metal can support a storm damage claim and help explain roof concerns. Photograph the date-sensitive evidence before cleanup begins when possible.
Check the Attic and Interior Spaces
The exterior tells only part of the story. Inside, start in the attic during daylight hours. Turn off the lights for a moment and look for pinpoints of sunlight through the roof deck. Small openings may not always mean an active leak, but they should be investigated.
Look for dark stains on rafters, damp insulation, mold-like growth, wet decking, or a musty smell. Also check for poor ventilation, such as extremely hot attic conditions, moisture buildup, or blocked soffit vents. Ventilation does not replace a sound roof, but it helps control heat and moisture that can shorten shingle life.
Inside the living space, inspect ceilings and upper walls for yellow or brown rings, bubbling paint, peeling drywall tape, or new discoloration near windows and chimneys. Keep in mind that water can travel along framing before it appears, so the stain may not sit directly below the source of the leak.
If you find active water during a storm, place a container below the drip, move valuables out of the area, and take photos. Do not puncture a bulging ceiling unless directed by a qualified professional. A water-filled ceiling can fail unexpectedly, and the source needs to be addressed quickly.
Document What You Find After a Storm
Photos make your inspection more useful. Take images from several angles, note the date, and write down the location of each issue. For example, record “lifted shingles above rear garage” instead of simply writing “roof damage.” Specific notes make it easier to compare changes over time and communicate clearly with a contractor or insurance adjuster.
Avoid making permanent repairs before documenting the condition, unless immediate action is needed to prevent additional damage. Temporary measures, such as safely covering exposed belongings indoors, are reasonable. Tarping, emergency repairs, and roof access are best handled by an experienced contractor, especially after severe weather.
Insurance coverage depends on your policy, the cause of damage, the age of the roof, and the condition documented during the claim process. Hail and wind damage can be hard to identify from the ground, while normal aging is generally handled differently. A professional inspection gives you clearer information before you make a major repair or replacement decision.
When to Call a Roofing Professional
Call for a professional inspection right away if you see an active leak, missing shingles, damaged flashing, a sagging roofline, storm debris on the roof, or interior water stains. The same applies if your roof is approaching the end of its expected lifespan or you are preparing to sell your property. Small problems often cost less to address before moisture reaches insulation, decking, framing, or interior finishes.
A good inspection should be straightforward. You should understand what was found, where it is located, what repair options are available, and whether the issue is urgent. Ask for photos and a clear explanation rather than feeling pressured into a replacement you do not understand.
For homeowners and property managers in the St. Louis area, Roofing & Exterior PROS provides free inspections and practical guidance for roof, gutter, siding, fascia, and soffit concerns. Whether the answer is a targeted repair, storm restoration support, or a full replacement, the goal is to protect the property and get the job done right.
A roof does not need to be failing dramatically to deserve attention. Take a careful look after the next clear day, save your photos, and act on changes while you still have options.
