Most metal roofs do not announce their problems. Asphalt curls and sheds granules where you can see it from the driveway; a standing seam or exposed-fastener panel roof can look sharp from the ground for years while the fasteners back out, the sealant in a headwall flashing hardens and cracks, and water finds its way to the decking an inch at a time. By the time there is a stain on a bedroom ceiling in Columbus, the entry point is usually several feet uphill of the stain and has been active for more than one season. An inspection is how you find that before the deck, insulation and drywall are part of the repair.
A metal roof condition assessment is a different job from a shingle inspection, and you should expect the person on your roof to work through the parts that fail first. On exposed-fastener panels, that means fastener condition across the field: screws backing out as panels expand and contract, neoprene washers that have gone hard and flat, over-driven screws that dimpled the panel, and the rust rings that tell you water has been sitting around a head. On standing seam, it means seam engagement, clip movement at the eaves and ridge, and whether the panels can still move the way they were designed to. Everywhere, it means the penetrations and transitions — pipe boots, furnace and bath vents, satellite mounts, chimney and sidewall flashings, valleys, end laps, closure strips at the ridge and eave. Cut edges and panel ends get checked for red rust, dissimilar-metal contact is noted where someone has run copper or steel against aluminium, and the finish is assessed for chalking and fading, which is cosmetic until it is not. Underside matters too: on an unvented assembly, condensation under the panels can rot a deck while the roof itself is sound, so an inspection that never goes into the attic is only half an inspection.
Drone roof inspection has made the first pass faster and safer, and on steep or slick metal it is often the only sensible way to see the whole field, photograph seams and capture the ridge and valleys without risking panel damage from foot traffic. Metal dents and scuffs under boots, and an inspector who walks a 30-year roof carelessly can cost you finish. But drone imagery will not tell you whether a fastener is loose, whether a sealant bead is still elastic, or what the deck feels like underfoot. Expect a combination: aerial imagery for coverage and documentation, hands-on checks at the details that matter, and an attic look where there is access. Ask for the photos. A written report with images is what you will need later for an insurer, a buyer, or a manufacturer.
A residential roof inspection after a spring or summer storm is usually about hail bruising, wind-lifted panel edges, and displaced ridge or gable trim — the kind of damage that is easy to miss from the ground across Upper Arlington, Gahanna and Dublin, where mature trees hide roof planes. A commercial roof inspection on low-slope metal or a metal-over-membrane assembly shifts the focus to drainage: ponding at internal gutters and scuppers, lap seam condition, curb and RTU flashing, and whether rooftop equipment traffic has crushed panel ribs. Commercial work usually also means a maintenance record, because most building warranties assume one exists.
A pre-purchase roof inspection answers a narrower question — how many years are left, and what will the first repair cost — and it is worth having independent of a general home inspection, which rarely assesses metal in detail. A roof warranty inspection is narrower still: manufacturer finish and weathertightness warranties typically require documented periodic inspection and prompt repair, and they exclude damage caused by someone else's work, so the inspection is partly about finding where another trade drilled through a panel for a satellite dish or a mini-split line set. Keep the documentation; warranty claims are lost on paperwork more often than on merit.
A free roof inspection is commonly offered as a storm-damage assessment, which is a real service but a limited one — ask whether it includes attic access, fastener-by-fastener review, a written report and photographs, or whether those are a separate, paid scope. What drives cost on a paid assessment is roof size, pitch, number of penetrations and planes, access, and whether you need documentation suitable for an insurer or a closing table.
