What Is A Roof Nail Pop?Where Should HVAC Vents Be Placed?
Also called back-out nails, homeowners can spot roof nail pops because of the tent-shaped rise on roofing shingles. Nails will typically push from below, causing the deformity. Driving down the nail once again without fixing the broken shingle may not provide a long-term fix to this problem.
Sometimes it can be tough to see nail pops on a roof because the bend or damage is reasonably low. So it should be proper to scrutinize the entire roof for nail pops instead of looking at it from afar.

What Causes Nails To Pop On Roof?
Improper installation for roofing components, such as shingles, can be the primary cause of nail pops. However, these problems can also appear because of other possible reasons. Some of these potential causes are:
Oftentimes, usage of the wrong roof nails can lead to nail pops. The International Residential Code (IRC) section R905.2 Fasteners indicates that shingles should use roofing nails made of an appropriate material like aluminum and galvanized steel. Also, the nails used should be 12-gages, at minimum, with a 3/8-inch minimum diameter for the head.
However, the IRC didn’t address the nail type or shank design of the recommended nails to use on roofing. It might be best to use ring shank nails to install shingles because these models generally have double the withdrawal resistance when compared to the standard construction nails.
Take note that failure to comply with those guidelines can lead to higher than usual risks of nail pops on roofs. Skipping out on buying and using a suitable set of nails may invite additional problems to households.
At this point, you might find it interesting to learn about the waterproof properties of plywood or the lack thereof. If so, you can read our post on that subject matter to understand more about that roofing material.
Low-quality materials used for roof decking can also cause nails to poke through the sealed surface. Nail fasteners can slip, which can result in the nail pulling up. Regular inspections by going to your attic and looking at the exposed ceiling can help prevent nails from popping up.
Otherwise, a long-term yet expensive solution is to replace the roof deck with a sturdier material. If so, prepare to spend about $700 to $900 per square foot for the replacement job.
Although nail guns are quite convenient to use, these tools aren’t ideal to operate during roof shingle installations. It’s because pneumatic nailers often drive nails at angles. Take note that a proper roofing installation typically demands hammering nails vertically to provide sufficiently tight seals.
Plus, shingles need to follow a nailing pattern. Applying nails on the roof using a random pattern will put the materials used at the risk of problems like the nails failing to penetrate the deck properly.

How To Fix Roof Nail Pops?
Before proceeding with any repair job on your roof, it’s best to practice proper safety measures. For instance, make sure to have an assistant holding the ladder as you climb it to reach the roof. Also, wear fitting footwear like safety shoes to ensure that your feet don’t get burned from stepping on the roofing’s hot surface.
Next, take note that the solution to repair roof nail pops often depends on the seriousness of the problem. In this section, you'll learn how to remedy this particular issue based on the condition of the popped-up nail.

Nail Broke Through the Shingle
If the nail broke through the roofing shingle, you might need to do more than use a hammer to return the nail to its original spot. Instead, this particular repair job might also demand the replacement of the broken shingle.
So you need to remove at least one piece of the damaged shingle and bring it with you to the store. Buy a new piece and return it to your roof. Keep in mind that you might need to buy more than one shingle if you find numerous popped nails on your roof.
Also, make your trip to the store quickly; spending too much time leaving your roof exposed may invite other concerns to your home. For example, pests like rodents and squirrels may take advantage of the new opening and claim the area under your roof as their new abode.
After getting the new shingle(s), carefully climb your roof and proceed with the next steps for this repair operation:
What You’ll Need
- Hammer with claw
- Appropriate nail(s)
- Asphalt cement
- Caulk gun
- Assuming that you have already removed the offending shingle, remove the popped nail using the claw side of your hammer.
- Replace the broken or damaged shingle with the new unit.
- Hammer a nail to the new shingle to secure it in place. Make sure that the location of the new nail is about 1-inch above the previous area.
- Slightly lift the shingle from the side and apply ½-teaspoon of asphalt cement using a caulk gun underneath it. Return the shingle to its original position afterward.
- Apply a layer of asphalt cement over the newly hammered nail to help seal it.
