Roof leak detection
Finding where the water actually gets in
Water that gets past the roof usually shows on the siding next, so siding damage and roof problems are frequently found together. Vinyl cracks and comes loose in wind, fiber cement holds up well but fails at joints and penetrations, and wood rots wherever a detail lets water sit. Repair is generally straightforward; the useful part is working out what put water there in the first place.
McLean County 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.
Usually a roof or flashing detail above it directing water onto the wall rather than away. Replacing the siding without fixing that just resets the clock on the same damage.
Often, though colour fades with exposure so new panels tend to look brighter at first. Where a profile is discontinued, panels are sometimes taken from a less visible elevation and the new stock used there.
