Missing or Blown-Off Shingles
in Raleigh, NC
Raleigh sits in the path of frequent summer thunderstorms and occasional hurricane remnants that push wind gusts well past 50 mph, making shingle loss one of the most common roofing calls we receive across neighborhoods like North Hills, Brier Creek, and Garner. Many homes in the Triangle were built in the 1980s and 1990s using three-tab shingles rated for only 60–70 mph winds, which age and lose their seal strips over time. Left unaddressed, even a single missing shingle can allow driving rain to saturate your roof deck, rot the sheathing, and push water into your attic insulation within a single storm cycle.
Telltale Signs
Warning Signs to Watch For
- Visible bare patches or dark exposed decking visible from the street or yard
- Shingle pieces or granule piles collecting in gutters or on the ground after a storm
- Curled or lifted shingle edges around the repair zone
- Water stains appearing on attic sheathing or ceiling drywall after rainfall
- Daylight visible through the attic when viewed from below
- Tar paper or felt underlayment flapping in the wind along roof edges
Root Causes
What Causes Missing or Blown-Off Shingles?
High Wind Storm Damage
Raleigh's warm, unstable summer air mass regularly spawns derecho events and fast-moving squall lines capable of producing straight-line winds exceeding 70 mph. Older three-tab shingles that have lost their factory seal strip adhesion lift at the tab edges, allowing wind to get underneath and peel them cleanly off the deck.
The Fix
Full Shingle Replacement with High-Wind Rated Materials
Damaged shingles are removed to bare decking, the deck is inspected for soft spots, and new architectural shingles rated for 130 mph winds are nailed using a six-nail pattern per shingle per NC building code updates adopted after 2012 storms, delivering a far more durable bond than the original four-nail installation.
Aged Sealant Strip Failure
Raleigh's humidity cycles between very wet summers and dry winter cold snaps, which accelerate the breakdown of the factory-applied asphalt sealant strip on the underside of shingles. Once that strip loses adhesion, shingles are held only by nails and become highly susceptible to wind uplift even in moderate 40–50 mph gusts common during spring pop-up storms.
The Fix
Re-Sealing and Partial Shingle Replacement
Loose but intact shingles are hand-sealed with roofing adhesive and re-fastened with ring-shank nails, while any shingles with cracked or brittle tabs are swapped out entirely, restoring the roof's wind resistance without a full replacement.
Improper Original Nailing Pattern
Many Triangle-area homes built during the 1990s construction boom were roofed quickly with crews using nail guns set too high, driving nails through the top of the shingle tab rather than into the nailing strip. This over-driven or high-nailed pattern dramatically reduces holding power, and Raleigh's freeze-thaw cycles in January and February work the shingles loose over winter until the first spring storm finishes the job.
The Fix
Nail Pattern Correction and Shingle Re-Fastening
A full inspection identifies shingles with improper nail placement; affected shingles are carefully lifted, old nails removed, and new nails driven correctly into the manufacturer's nailing strip, then sealed, restoring code-compliant wind resistance across the affected field.

Which Cause Applies to You?
Check the signs you're observing to narrow down the likely root cause before your inspection.
| What You're Seeing | High Wind Storm Damage | Aged Sealant Strip Failure | Improper Original Nailing Pattern |
|---|---|---|---|
| Shingle loss concentrated on one side of the roof facing the prevailing storm direction | |||
| Multiple shingles loose across the entire roof surface, not just storm-side | |||
| Shingles found in yard still intact but cleanly popped off at the nail line | |||
| Granule loss concentrated at shingle edges with curling visible before storm | |||
| Attic water staining appearing immediately after a single heavy rain event | |||
| Nails protruding or visible at shingle edges when viewed from the roof surface |
