Underlayment replacement
The secondary barrier under the covering
Flashing is what seals every junction on a roof — walls, chimneys, valleys, penetrations — and it is where most leaks begin. It fails through corrosion, through movement opening the joint it was set into, and through having been installed as a surface detail rather than stepped properly into the courses. Replacing it means working into the surrounding material rather than sealing over the top, which is why it costs more than a patch and why it lasts.
Berrien County is far enough south to take the inland remnants of Gulf and Atlantic hurricane systems, and that is the storm profile that matters here. By the time these systems reach Berrien County the wind has dropped below the headline numbers but is still sustained for hours, which does something different to a roof than a short violent gust — it works shingle tabs loose over an extended period and drives rain horizontally under courses that would shed a normal downpour. The heat and humidity do the rest. Roofs here run hot for most of the year, which ages the shingle and hardens every rubber and sealant component, and the humidity means anything that gets wet inside the roof stays wet.
It is thinner material in the most exposed position, and it sits across a joint between two things that move at different rates. On most roofs the flashing is the first component to need attention, often by a decade.
Yes. It means lifting and reinstating the surrounding courses, but it is a localised job on an otherwise sound roof and far cheaper than replacement.
