Best Roofing Nails & Materials: A Homeowner’s Guide
Grayson Roofing & Chimney has been installing and replacing roofs across northern New Jersey since 2012 and one of the most common mistakes we find on failing roofs isn’t the shingles. It’s the nails. Most homeowners never think about roofing nails. But the wrong fastener wrong gauge, wrong coating, wrong placement can unravel an entire roof system within a few years. Our roofing and chimney services cover everything from full replacements to repair work where improper nailing was the root cause of the failure.
Here’s what you actually need to know.
Why Roofing Nails Matter More Than You Think
A shingle roof isn’t held together by weight. It’s held by thousands of nails. If even a fraction of those nails corrode, back out, or were driven at the wrong angle, you’re looking at lifted shingles, water intrusion, and eventually structural damage.
In Bergen County, Passaic County, and Morris County, roofs face freeze-thaw cycles, ice dams, and coastal humidity. Those conditions accelerate nail corrosion faster than contractors in milder climates account for.
The nail is often the first thing to fail and the last thing the homeowner blames.
The Right Roofing Nails for NJ Homes
Hot-Dipped Galvanized — The Standard Choice Hot-dipped galvanized nails have a thick zinc coating that resists rust far better than electroplated alternatives. For most asphalt shingle installations across northern New Jersey, these are the minimum acceptable standard. Electroplated “galvanized” nails look similar but corrode significantly faster don’t let a budget contractor substitute them.
Stainless Steel — The Premium Option Stainless steel roofing nails are the right call near the coast or in areas with high humidity. They cost more, but they won’t rust, period. For slate roofing, stainless steel isn’t optional it’s required, since slate outlasts any other fastener material and the nails must keep pace.
Aluminum Nails — Know the Limitations Aluminum nails are lightweight and corrosion-resistant, but they’re soft. They shouldn’t be used with heavier materials like tile or metal roofing. They’re also incompatible with pressure-treated wood, which causes an electrochemical reaction that accelerates corrosion of both the nail and the lumber.
Nail Sizing: Length and Gauge
Minimum Length For standard three-tab or architectural asphalt shingles, nails need to penetrate at least ¾ inch into the roof deck — which means 1¾ inches is typically the minimum. On re-roofing jobs where new shingles go over existing material, longer nails (up to 2 inches) are often required to reach solid wood.
Gauge 11-gauge and 12-gauge nails are the industry standard. Thinner nails 14-gauge or beyond are more prone to bending during installation and have less holding power in high-wind conditions. Given how frequently Essex County and Hudson County see sustained winds, this matters.
Ring Shank vs. Smooth Shank Ring shank nails have ridged shanks that grip the wood fibers and resist pull-through better than smooth shank. They’re particularly valuable in high-wind zones and are required under the GAF installation specs that come with GAF Master Elite certification which Grayson Roofing & Chimney holds.
Common Nailing Mistakes That Void Warranties
High Nailing Nails driven above the designated nailing zone miss the overlapping shingle layer and lose holding strength immediately. This is one of the most common errors on fast, low-bid jobs.
Overdriven Nails A nail driven too deep tears through the shingle mat. The head disappears into the material, leaving a weakened point and zero uplift resistance. Pneumatic nail guns set at the wrong pressure do this constantly when operators aren’t paying attention.
Underdriven Nails Heads that stick up above the shingle surface puncture the shingle above them as the roof flexes creating a leak point that’s almost impossible to trace back to the nail.
Too Few Nails Asphalt shingles typically require four to six nails per shingle depending on the wind zone and manufacturer specifications. Cutting corners on nail count is how budget contractors hit lower prices. It’s also how roofs fail in the first storm.
Material Selection Affects Fastener Requirements
Different roofing materials call for different fasteners entirely.
- Asphalt shingles: Hot-dipped galvanized or stainless, 1¾–2 inches, ring or smooth shank
- Metal roofing: Specialty screws with neoprene washers — not nails at all in most systems
- Slate and tile: Stainless steel nails only, copper in some traditional applications
- Flat roofing (TPO/EPDM): Mechanical fasteners or adhesive systems — no exposed nails
- Cedar shake: Stainless or hot-dipped galvanized, never aluminum
Matching the fastener to the material isn’t optional. Using the wrong nail on slate, for example, can crack tiles during installation or cause failure within years as the metal reacts with the stone.
What to Ask Your Roofer About Nails
Before any contract is signed, ask:
- What nail type and gauge are you using?
- Are they hot-dipped galvanized or stainless?
- What’s your nailing pattern per shingle?
- Do you manually check nail depth or rely solely on the gun?
- Will this installation comply with GAF installation specs?
A contractor who can’t answer those questions clearly shouldn’t be on your roof.
