Roofing in Ohio splits with the sky. On the lake, snow weight and ice at the eaves are the ordinary threat, and a warm attic makes that dam worse. Inland, hail and wind bruise coverings, and leaks often show when a brief snow melts into rain. River counties add driven rain under edges that a dry cold would leave alone. Summer attic heat bakes all of them. Say which pattern actually hit your slope.
Look from the ground for a sagging eave, granules, a wavy ridge, or a porch that dips. Old layers hide a soft deck until tear-off. A pipe-boot patch is not a new roof. Chimney and sidewall flashing are where the water returns if the field is all you replace. Lake slopes may still be loaded when inland slopes are bare. Do not walk a snowy pitch to prove a stain you can see indoors.
Hail marks and ice-dam stains are different evidence. If a claim is possible, photograph before anything is torn off, and note where the water enters. Bath fans that dump into the attic feed dams on the cold eave and rot the same deck the hail bruised. Say if icicles are a yearly event on one side only. Ventilation belongs in the scope with the shingles.
A steep older roof near the lake sheds and dams differently from a lower inland subdivision roof. Valleys full of tree litter hold melt. Additions create the pocket where ice sits against the taller wall. The scope should name boots, valleys, and chimney metal. Say if the deck feels soft, and say whether the storm was a squall off the water or a hail line across open country.
Say leak or replacement, and say whether snow is still on the house. Name the town so the cause matches the climate. Leave damaged shingles in place until the photos exist. Call the number on this page.
