Starter Strip Trouble: Why Florence, SC Roofs Lose Their Edge Shingles First in a Storm
Wind pressure on a sloped roof is not spread evenly. The corners and the bottom edge, the eaves, can see uplift forces several times stronger than the wide middle of the roof. That is why, after a Pee Dee storm blows through, the damage so often shows up as a peeled-back or missing row of shingles right along the edge rather than a hole in the center. The edge takes the hardest hit, every single time.
That matters in Florence, SC because our worst wind does not usually arrive as a tidy straight line. It swirls, gusts, and lifts, and the roof edge is where that lifting energy concentrates. Understanding why the edge fails first helps you know where to look after a storm and whether what you are seeing is a quick fix or the start of a bigger problem.
The Problem: Shingles Curling Up Along the Eaves
Picture a homeowner walking the yard the morning after a windy night. The field of the roof looks fine, but down along the bottom edge a few shingles are standing up, flipped back, or gone entirely, leaving the black underlayment or bare deck showing.
This is one of the most common wind complaints we hear about in the Pee Dee. It looks alarming, and it can be serious, but it is also one of the more predictable ways a roof reacts to gusty weather. The edge is simply the weakest point in a wind event.

The Diagnosis: Why the Edge Gives Out
There are a few reasons the eave row is so vulnerable, and most of them come down to how the roof was built and how old it is.
The starter strip is doing a quiet, critical job
The bottom row of shingles is supposed to sit on top of a starter strip, a special first course with a continuous line of factory adhesive near the edge. That glue line grabs the tabs of the first visible row and holds them down against uplift. When a roofer skips the starter strip and just flips a regular shingle backward instead, the adhesive ends up in the wrong spot. The edge then relies on a few nails and gravity, and in a strong gust that is not enough.
Sun and age weaken the seal
Even a properly built edge loses strength over time. The self-sealing adhesive on asphalt shingles softens in heat, bonds, and then slowly loses grip as the shingle ages and the oils bake out. Our long Pee Dee summers accelerate that. Say a roof is fifteen years old and faces south or west; the edge seal there may have grown brittle, so the next good gust peels it where a newer roof would have held.
Drip edge and overhang details
If the metal drip edge along the eave is loose, missing, or was installed under the shingles incorrectly, wind can get underneath and pry upward. A slightly over-long shingle overhang, hanging too far past the edge with nothing behind it, acts like a little sail and catches wind too.
The Fix: What Actually Resolves It
The good news is that an edge failure caught early is usually a repair, not a replacement.
Reseal and refasten where it is isolated
If only a handful of shingles along one eave lifted and they are not cracked, a roofer can often lift them, add fresh roofing cement or sealant under the tabs, and renail where fasteners backed out. On a newer roof with a sound starter strip, this kind of targeted roof repair can restore the edge for a fraction of a full job.
Replace creased or torn shingles
Shingles that folded back far enough to crease are compromised even if they flipped back down. The crease is a future leak and crack point. A realistic example: a homeowner finds six shingles lifted after a gusty night, and the roofer determines three are merely unsealed while three are creased. The three creased ones get swapped for matching replacements and the rest get resealed.
Address the root cause if the starter strip is missing
If the roofer peels back the edge and finds no real starter strip at all, resealing is only a bandage. On an older roof, that missing-starter pattern often shows up all along the eaves, which pushes the conversation toward a larger repair or, if the roof is near the end of its life anyway, a replacement. If you are unsure which way it leans, our storm damage triage guide helps sort urgent from can-wait.
When to act
Edge damage is not usually a drop-everything emergency unless the deck is exposed and rain is coming. But it should not wait for months either, because the row above the gap is now the new edge and will peel next. If you spotted lifted shingles after a storm, photograph them before anything changes, document the date, and get an honest look. You can get matched with a local roofer for a free inspection to find out whether you are looking at a reseal or something bigger.
Frequently Asked Questions
My shingles flipped up in the wind but laid back down flat. Am I fine?
Not necessarily. A shingle that lifted enough to flip has likely broken its adhesive seal, and one that creased on the way back down is weakened even if it looks flat from the ground. The seal may not re-bond on its own, especially in cooler fall weather. It is worth having the edge checked and resealed before the next gusty front.
Could an edge failure be part of an insurance claim?
It can, particularly if a documented wind event caused it rather than plain age. Insurers look closely at whether the damage is storm-related or wear-related, so clear photos and a date matter. Our overview of filing a South Carolina storm and hurricane claim and the steps for documenting damage after the wind quits explain what to gather.
Why does only one side of my roof lose edge shingles?
Wind hits the windward eaves and corners hardest, so the side facing an open yard, a field, or the direction a storm came from usually takes more uplift than a sheltered side. Sun exposure plays in too; a west-facing edge that bakes all afternoon may have a weaker seal than a shaded north edge, so it peels first even in the same gust.
Is a missing starter strip something I can see myself?
Rarely from the ground, and getting up to the edge safely is hard. What you can watch for is a repeating pattern: if shingles lift along the whole bottom edge rather than in one random spot, that often hints the starter detail was never right. A roofer can confirm it by gently lifting the first course during an inspection.
