Why are shingles curling and nails popping on your roof?
Kevin Gray of Klaus Roofing Systems of Nashville inspected a roof in Chapmansboro, TN. The roof is made of 3-tab roof shingles, which were commonly used but due to their low quality, roofing contractors who care about the quality of the roof products that they install for homeowners avoid using 3-tab shingles.
A contractor who installed this roof used a round shank nails instead of ring shank nails. Ring shank nails are stronger and more powerful when attached, compared to round shank nails. They are used for decking, underlayment, siding, and roofing installations. The contractor wanted to take a shortcut and save a few bucks, so he used round shank nails instead.
Round shank nails are commonly used for everyday projects at home, for framing, or for construction applications. They are the most economical option, but the downside of round shank nails is that they lose their strength when applied to wood due to wood contracting and expanding due to moisture, therefore they are not a suitable option for a roof installation.
Watch this video Curling Shingles and Popping Nails to see how the shingles on this roof curled due to nails popping up from the decking.

A closer look at a few terms we used:
3-Tab Roof Shingles are not used anymore by contractors due to their low quality. Three-tab shingles are 50% lighter than architectural shingles, which makes them less durable. High quality is our priority at Klaus Roofing Systems of Nashville, therefore we only use architectural shingles.
Round shank nails are commonly used for everyday projects at home, for framing or for construction applications. They are the most economical option. The downside of round shank nails is that they lose their strength when applied to wood due to wood contracting and expanding due to moisture.
Ring shank nails are stronger and more powerful when attached compared to round shank nails. They are used for decking, underlayment, siding, and roofing installations.
