Nail pops are indicative of structural issues within a home. They occur as temperatures and humidity levels fluctuate daily, causing roof sheathing to expand and contract, eventually creating nail pops.
Quick action against nail pops can protect your roof from leaks and further damage to your home, as well as protecting them from becoming dislodged during high winds or storms.
Repairing Nail Pops
If you spot nail pops in your roof, it is imperative that you contact a roofing professional as soon as possible. Ignoring these nails may lead to serious consequences like stained ceilings and water infiltration, as well as expensive repairs.
Nail pops can occur for various reasons. Poor construction or installation practices could be the culprit; thin roof sheathing allows nails to work their way out over time, as can an improper angle and force of drive into sheathing shear.
Nail pops can also result from using nails of incorrect type or size, leading to weak spots in roof sheathing and invalidating any warranties associated with your new roof. Finally, over time settling of your house can put pressure on nails that were not installed correctly, leading them to pop out of wood due to improper installation techniques.
Identifying Nail Pops
Once you notice nail pops on your roof, it is vitally important that you contact a roofing expert immediately. They can conduct an in-depth examination to identify what is causing these nail pops and address any underlying issues immediately.
Nail pops are unsightly and may lead to water infiltration in your home, creating gaps that allow wind-driven rainwater to seep under your shingles and enter your sheathing, leading to rotting sheathing, stained ceilings, among other problems.
Nail pops can be caused by various factors, from improper installation to using ineffective nails. Builders frequently utilize Oriented Strand Board (OSB), a wood similar to plywood that expands and contracts throughout the day and night causing nails to loosen over time. Furthermore, different nail types make an impactful statement: Ring shank nails tend to back out more easily from sheathing than smooth-shank ones.
Preventing Nail Pops
Nails are necessary components of roof shingles to secure them to roof decking and protect it from moisture damage, with rings that grip wood for secure attachment and require regular driving in. In order to stay in their proper places over time and not pop out over time. A number of conditions can lead to nail pops during installation as well as over time due to shifting foundations of houses or damage during maintenance causing nails to pop out over time – damage during assembly being one such cause, as well as natural house settlement.
Under-ventilated attics allow hot and humid air to expand roof sheathing boards, pushing up their nails. Over time, this can cause them to rise up from their position before breaking or blowing away in strong winds.
Roof nail pops create an entryway for water penetration into your roof system, leading to leakage or even significant rot damage. Proper attention given to nail pops can prevent extensive damage and costly repairs being incurred later. A professional roofing expert can assess your system for possible causes before providing needed repairs for maximum home protection.
Removing Nail Pops
Nails that secure shingles to a roof may pop due to any number of reasons, including poor craftsmanship; nails not driven into roof sheathing securely can become loose over time, leading them to protrude over time and eventually rise up through it. Low-quality wood used as decking may dislodge nail heads too – such as OSB which expands and contracts daily due to changes in temperature and humidity changes; nail length and sheathing design factors also play a part; smooth shank nails have an easier time popping than ring shank nails do.
Nail pops can allow rainwater driven by strong winds to seep beneath your shingles and enter your home, as well as increasing the likelihood that other shingles lift or dislodge during storms and high winds. An experienced roofing professional should inspect your roof to identify ways of fixing nail pops and preventing further instances.
