Valley leaks
Where two roof slopes meet
A new roof is more than the covering: decking, underlayment, ice and water membrane at vulnerable points, drip edge, flashing at every junction, and a ventilation system that balances intake against exhaust. Most premature failures trace back to one of those details being skipped rather than to the shingles themselves — which is why two roofs with identical materials can differ by a decade in service life.
Gainesville sits in the Blue Ridge foothills, which puts it in a different roofing climate from most of Georgia. The mountains get real freeze-thaw cycling: water works into a hairline gap in flashing during the day, freezes overnight, expands, and opens the gap a little wider. Repeat that through a Hall County winter and a joint that was watertight in October is leaking by March. Ice at the eaves is the other one — meltwater running down a warm roof refreezes over the cold overhang and backs up under the shingle course, which is how water ends up inside a roof with no visible damage at all. Steep pitches shed snow well but make access harder, and older stock here runs to standing-seam and pressed metal, which fails at the fastener rather than the panel.
Gainesville has a population of about 42,296, and the housing stock here sets the pattern for what fails first on a roof.
Detailing, not materials. Flashing reused instead of replaced, ventilation left unbalanced, drip edge omitted, or nails driven high or overdriven — each shortens the life of an otherwise identical roof. These are the things worth asking about.
No. It is the cheapest component and the most common failure point. Reusing it on a new roof means the first thing to fail will be the old part you kept.
