Roofing & Roof Leak Repair: what to know
Where leaks actually come from
Failed pipe boots lead the list on asphalt-shingled Kentucky homes: the rubber collar around a plumbing vent cracks after ten or twelve years of ultraviolet exposure and lets water straight in. After that come step flashing where a roof meets a wall, chimney counter-flashing, worn valleys, nail pops that back out and lift a shingle, and ice damming at the eave after a hard freeze. Whole-roof failure is comparatively rare; detail failure is the norm.
And sometimes it is the gutters
A blocked gutter that backs water up under the first shingle course at the eave produces a leak that looks exactly like a roof failure. It gets misdiagnosed regularly, and shingles get replaced that were never the problem. If a leak appears near an exterior wall after heavy rain, the gutters are worth ruling out before anyone starts tearing off.
Water does not fall straight down
It runs along the top of the decking, down a rafter and across a joist before it emerges at the first low point, often several feet from the entry, sometimes in a different room. That is why repairs based on where the stain appeared so often fail. Tracing it from the attic, following the wet path in the insulation and the darkened line on the framing, is the part that takes the time.
Tarping is triage
An emergency visit stops the water. A properly installed tarp runs over the ridge and is secured so wind cannot get under it, and buys days to weeks, not a season. Expect the permanent repair to be scoped separately once the roof can be inspected dry.
