Roof nail pops on a roof can be caused by a variety of reasons. During climate changes, expansion and contraction can cause to the nail to pop up. When this happens, the roof shingles become loose and start to lift. Other causes of roof nail pops can be shingles that were not nailed tightly during the roof installation. Additionally, the roof installers could have used nails that were too short. It really is not uncommon to have a few roof nail pops, but left unattended, the roofing system will be compromised, and water will penetrate the wood causing roof leaks and interior damage.
There are lots of reasons why roof nail pops can occur, but the important thing is to take care of them as soon as you notice raised shingles. If the roof nail pops are dealt with immediately, a fix can be quite simple. Removing and replacing the loose nails and sealing the roof shingles down will take care of the problem and will prevent other more expensive damages from occuring.
