Roofing in Columbus is hail, wind on a flat inland city, and freeze-thaw that opens valleys. Snow does not live on the house for months. It melts, runs, and refreezes at the eave or in the pocket where a low addition meets the old wall. Subdivision roofs take hail on open exposures and then a summer of attic heat. Older roofs hide several layers and a chimney flashing that has left the mortar. If you only chase big storms, you miss the slow leak.
From the yard, look for granules, a wavy ridge, and a porch that dips. A boot patch is not a tear-off. Soft deck stays hidden until the layers come off. Sidewall flashing beside a dormer is a frequent miss on these streets. Say if the attic bakes in summer and grows icicles on one eave after a melt. That pairing means warm air, not only a tired shingle.
Hail bruises and wind creases are different from age and from each other. If a claim is possible, photograph from the ground or an upstairs window before tear-off. Note whether water shows at the chimney, the valley, or a ceiling that matches neither. The scope should name boots, sidewalls, and the ridge. Ladders on tight older lots have to fit a side yard. Newer lots are easier to reach and more exposed to hail.
A bath fan dumped into the attic helps an ice dam on the same house the July heat is baking. Blocked soffits do that even on a house with a ridge vent. Ask about the air path. Tree litter in a valley holds melt against the covering. Do not climb an icy patch to confirm a stain the bedroom ceiling already confirmed. Leave damaged pieces in place until photos exist.
Say leak or replacement, hail or thaw, older street or new subdivision. Say if ice is still sitting in the valley this week. Call the number on this page.
