Chimney and flashing leaks
Leaks around the chimney stack
Individual shingles come off in wind, crack with age, or lose their seal and lift. Replacing a small number is a straightforward repair that restores the roof for years. The judgement is whether the surrounding shingles are sound enough to lift without breaking them, and whether colour can be matched on a weathered roof — on an older covering, replacements rarely blend, which is cosmetic rather than functional but worth knowing before the work starts.
McLean gets the full range — freeze-thaw cycling through winter, severe convective storms with hail and straight-line wind in spring and summer, and enough temperature swing between them to work every joint on the roof loose. Freeze-thaw is the quiet one: water finds a hairline gap in flashing, freezes overnight, expands, and opens it slightly wider, repeating through a McLean County winter until a joint that was watertight in October is leaking by March. Spring brings the loud damage, and derechos have put straight-line wind through this region at speeds that take ridge caps and whole shingle courses. Housing stock here is older than average, which means a lot of roofs where the flashing has already been through several decades of that cycle.
McLean has a population of about 743, and the housing stock here sets the pattern for what fails first on a roof.
Rarely exactly on a roof more than a few years old — weathering and granule loss change the colour, and manufacturers adjust blends over time. The repair performs identically; it just may be visible from certain angles.
There is no fixed number. The signal is pattern: isolated damage from a specific event is a repair, while shingles failing in several unrelated places within a season means the covering has reached the end of its life.
