What does one missing shingle cost if you leave it?
Updated August 2026
← What skipping home maintenance costs
Replacing a blown-off shingle promptly runs $150–400, but leaving the gap open lets one storm rot the deck and can void the roof warranty. A missing shingle exposes the tar-paper underlayment and the nail heads beneath it, and underlayment is a temporary shield, not a roof. The next wind-driven rain pushes water past it to the wood decking, and from there it wicks into the sheathing and down the rafters. What looks like a single cosmetic gap is really an open door, and water is very good at finding it. A quick patch closes that door before it becomes a rebuild.
The escalation ladder
Every row below is the same leak, left a little longer. The top is a cheap warning; the bottom is a claim.
| What happens | Typical bill | How fast |
|---|---|---|
| A roofer replaces the missing shingle and its neighbors | $150–400 for the patch | One visit |
| Several shingles blew off and the section is redone | $400–900 to reshingle the area | Same appointment |
| Exposed decking gets wet before the repair | $800–2,000 to replace soaked sheathing | A storm or two later |
| The leak stains and soaks the ceiling below | $1,000–4,000 in interior repairs | A few months |
| Wind damage voids the warranty and ages the roof | $8,000–20,000 for early replacement | Seasons of neglect |
Warning signs
Spotting a missing shingle is mostly about looking up after the weather that causes it. Following any windstorm, scan the roof from the ground with binoculars for gaps, dark patches where a shingle is gone, and shingles hanging or flipped up. Check the yard and along the foundation for shingles or shingle fragments that blew down, a dead giveaway that the roof lost some. Heavy granule loss in the gutters and shingles curling or lifting at the edges mean the whole roof is getting brittle and shedding, so more will go with the next gust. You do not need to climb up; a slow binocular scan after each storm catches almost all of it.
The prevention math
The habit costs nothing but ten minutes: a post-storm scan of the roof from the ground, then a $150–400 patch on anything you find, done before the next rain. That patch is roughly one percent of the $8,000–20,000 early replacement a chronic leak can force. Keep spare shingles from the original install in the garage so a roofer can color-match, and act the same week, since underlayment is only rated to hold out water briefly. When gaps and granule loss start showing up all over, the roof is telling you its age; compare notes with how long an asphalt shingle roof lasts and how often to replace it. The seasonal routine lives in the asphalt shingle roof maintenance checklist.
Every line in that table starts with a skipped 10-minute task. OnOtto keeps the 10-minute version on your calendar so the $2,000 version never happens.
Get the nudge before the billFrequently asked questions
Can I replace one missing shingle myself?
It is doable if you are comfortable on a roof and the pitch is gentle, but it is easy to get wrong. You have to break the sealant on the shingles above, pull the old nails, slide the new shingle in, and re-nail without cracking neighbors or leaving exposed heads, all while matching color and pattern. On a steep or high roof, the fall risk is not worth the $150–400 a roofer charges. Whoever does it, do it soon: an open gap is on the clock every time it rains.
How long can underlayment protect the roof with a shingle gone?
Not long. Felt or synthetic underlayment is a secondary, temporary water barrier meant to back up the shingles, not replace them, and it is rated in weeks of direct exposure, not months. Sun degrades felt and UV embrittles it, while wind-driven rain works water under it fast. Once the underlayment fails, the next stop is the wood deck. Treat a missing shingle as a leak that has not started yet, and close it before the underlayment is all that stands between the storm and your sheathing.
Will a missing shingle void my roof warranty?
It can. Most shingle manufacturers' warranties require the roof to be maintained, and they exclude damage that follows from a known, unrepaired problem, so a leak that traces back to a shingle you left missing may not be covered. Wind damage itself is often outside the material warranty and falls to your homeowners insurance instead. The way to keep both in play is to repair promptly and keep receipts. A documented $200 patch protects the warranty; a neglected gap can forfeit it.
