Missing shingles may not seem like a major problem at first. If only one or two are gone, it’s easy to assume the rest of the roof is fine. But even a small exposed area can let water get underneath the roofing system and cause damage.
What Causes Shingles to Go Missing?
For homeowners in Mechanicsburg, Harrisburg and Perry County, wind, storms, falling branches, and aging shingles can all lead to missing or lifted shingles.
Sometimes, though, missing shingles point to a larger issue. If shingles are coming off easily, the roof may have improper installation, worn-out seal strips, brittle shingles, or age-related failure.
| Expert tip: One of the most common installation mistakes behind blow-offs is “high nailing,” where nails are placed above the manufacturer’s nailing zone. The shingle may look fine for years, but it has far less holding power when strong winds hit. |
Why a Small Gap Can Lead to Big Problems
Once a shingle is gone, the underlayment and decking underneath are exposed to rain, snow, and ice. Over time, this can lead to leaks, wood rot, mold, and interior damage.
Underlayment is designed as a backup layer, not a long-term water barrier. Once exposed to sun and weather, it breaks down faster than many homeowners expect, so a gap that holds up for a few weeks may not hold up for a full season.
The damage can also spread. One missing shingle can quickly turn into several after the next storm, since wind catches the exposed edges of neighboring shingles more easily.
Check the Surrounding Shingles Too
The shingles near the missing area are often loose, creased, or no longer sealed down properly. If those aren’t addressed, the problem can continue.
Creased shingles are easy to miss. When wind lifts a shingle and bends it back, it leaves a faint horizontal line across the surface. That shingle has usually lost its seal and is likely to be the next one to blow off.
What to Do If You Spot Missing Shingles
The safest move is to have the roof inspected as soon as possible. In the meantime:
- Stay off the roof. Check from the ground or use binoculars, and look for shingle pieces in your yard after storms.
- Take photos of any visible damage, especially after a storm, in case you need them for an insurance claim.
- Watch for interior signs like ceiling stains or damp spots in the attic.
A professional roofer can determine whether a simple repair is enough or whether the roof has more widespread damage. If needed, they can also tarp the area to prevent further water damage until repairs are made.
