Shingle Re-Nailing: What It Is and Why It Matters

If your roof’s been around a while—or you’ve just had storm damage—you might hear a contractor mention “shingle re-nailing.” But what exactly is it? And is it something you should take seriously?

At L&L Roofing & Construction, we believe in doing things right, with no shortcuts. So let’s break down what shingle re-nailing is and why it’s often the right move for homeowners here in Gainesville, Georgia, and surrounding areas like Cumming, Dahlonega, and Flowery Branch.

What Is Shingle Re-Nailing?

Shingle re-nailing is the process of driving new nails through existing asphalt shingles to re-secure them to the roof decking below.

It’s typically done:

• During a roof re-cover (installing new shingles over old ones)

• After storms that cause uplift or nail pop

• To meet updated building code requirements, especially if the original fasteners were improperly spaced or underdriven

Many older roofs (especially pre-2000s) used fewer nails per shingle than today’s codes require. The 2021 International Residential Code (IRC) mandates a minimum of four nails per strip shingle, and in high-wind areas, even more.

Why Would You Need Shingle Re-Nailing?

Here’s when and why shingle re-nailing makes sense:

1. Storm Damage Repairs

Hail or wind may lift shingles, loosening the original fasteners. Re-nailing ensures shingles are firmly re-attached and won’t flap or leak in the next storm.

2. Building Code Compliance

When performing a roof re-cover or repair in Georgia, inspectors may require re-nailing to meet current fastener spacing codes (like those outlined in the IBC and IRC).

3. Preventative Maintenance

Over time, nails can back out or rust—especially if not driven into solid decking. This causes visible nail pops, allowing moisture to sneak in. Re-nailing resolves that before bigger problems arise.

Is Re-Nailing Better Than Replacing?

That depends.

• If the shingles themselves are worn, curled, or cracked—replacement is likely the better option.

• If the shingles are in good shape but loose or improperly fastened, re-nailing can restore proper function without the cost of a full replacement.

At L&L Roofing, we often perform re-nailing as part of a hail damage repair or insurance claim project to help homeowners stay protected without unnecessary costs.

Real-World Example: Creekside Estates, Cumming

A recent customer in Creekside Estates had a re-roof that combined standing seam metal and shingle roofing. Before we laid new shingles, we re-nailed the deck to meet code and prevent uplift—ensuring a secure, long-lasting system.

FAQs About Shingle Re-Nailing

How do I know if my roof needs re-nailing?

If you see nail pops, loose shingles, or you’ve had roof work done before 2006, have us inspect it. We’ll check fastener spacing and decking integrity.

How long does shingle re-nailing take?

For a standard-size home, it usually takes a few hours to a day, depending on the size and condition of the roof.

Does re-nailing affect my insurance?

Yes—especially after storms. Insurance companies often cover re-nailing if it's part of a repair or replacement needed due to hail or wind damage.
