Roof leak detection
Finding where the water actually gets in
Gutters are a roofing problem more often than people expect. Overflowing or incorrectly falling gutters push water back under the shingle edge and down the fascia, which rots timber and can show up inside as a leak. Blockage, bad fall, undersized downspouts and failed joints are the usual causes, and they are frequently found during a leak call rather than reported as problems in their own right.
Dane 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 Dane 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.
Indirectly and commonly. Water backing up in a blocked gutter gets under the first shingle course and onto the decking, which presents inside exactly like a roof leak. Clearing the gutter is sometimes the entire repair.
Twice a year as a baseline, more with overhanging trees. The autumn clearing matters most — a gutter that goes into winter blocked is the one that overflows and rots the fascia.
