Metal roof leaks
Fasteners, washers and seams
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.
Iowa County has a winter long enough and cold enough that ice damming, not storm damage, is the dominant cause of roof leaks. The mechanism is heat loss rather than weather: warm air escaping into the attic melts snow on the upper roof, the meltwater runs down and refreezes over the cold overhang, and the resulting ridge of ice backs water up beneath the shingle courses until it finds a way in. The roof itself is usually in perfect condition. Repeated through a Iowa County winter, freeze-thaw also works every flashing joint progressively looser, and spring brings hail and straight-line wind on top. The reason this matters is that fixing an ice dam leak by working on the shingles does not work — the problem is insulation and ventilation, and that is a different job.
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.
