Repairing a lifted nail, like the one pictured below, can be accomplished by prying the edge of the shingle loose enough to slip a small piece of wood (like a paint stirring stick) between the head of the nail and the underside of the shingle above it. Another piece of wood on the top side of the shingle will protect it while striking lightly with a mallet to set the nail back in place. If the fastener has already forced itself through the face of the shingle, replacement of the entire shingle is required. A dab of mastic at the hole is only a temporary repair.

  Most of the time when we see a few popped nails on a roof, they are called out for repair; but, occasionally, a roof has large areas of popped fasteners and requires partial replacement. 

    Any roofing repair beyond setting a few popped nails should only be performed by a licensed professional. Also, if you are uncomfortable with heights or not used to working on an inclined surface, we recommend letting a roofer do your nail pop repairs.

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
