Nails in drywall will pop-out for a number of reasons, most of which are not a structural concern, but more of a cosmetic issue. The problem of nails popping out is much more common than drywall screws popping out.
Most common reasons
- Green lumber
Homes that are newly built and have wood framing (often called green lumber) may experience shrinkage of the wood and some warping or movement as the wood dries out. This usually occurs in the first one or two years, and then stops.
- Drywall taking on moisture
Drywall that gets delivered to a home may take on or absorb, moisture prior to being installed. It also may take on additional moisture when first spray painted. Then, as the drywall dries out, pop outs occur.
- Truss lift
Seasonal changes may cause a home’s roof trusses to shift or lift a little. This movement places stress on the drywall and pop outs occur.
- Seasonal changes
During rainy seasons, expansive soils may swell up causing the structure to move; likewise it moves again when the soils dry out.
- Other reasons include
Earthquake movement, not enough nails placed properly to hold the weight of the drywall, wind loads and pressure changes occurring inside the home.
It is moisture changes in the wood, drywall or soil that causes the majority of pop outs. Seldom is there concern of a structural problem or failure. Most home that have drywall nails will experience some pop outs in places.
