#14 Metal Roofing Screws 1-1/2in Charcoal - Durable Fastening

In this review of the #14 Metal ROOFING SCREWS, the bottom line is clear: these screws are aimed at homeowners and contractors who need a straightforward, durable fastener for metal roofing on wood structures. The biggest reason to buy is reliable hold and a color-matched head that blends with corrugated roofing, making them ideal when appearance and weather resistance matter. Our review focuses on how they perform in typical roofing installs and whether the coated head and EPDM washer deliver on corrosion and leak prevention.

Key Features

• Hex Washer Head: The 5/16in hex washer head gives strong torque transfer for quick driving with standard sockets or a power gun.
• EPDM Washer Seal: The ~9/16in EPDM washer provides a resilient seal around the head to reduce water ingress at each fastener point.
• #14 Shaft Size: The.242in shaft size is thicker than smaller sheet metal screws, offering improved shear strength for metal-to-wood connections.
• 1-1/2in Length: The 1-1/2in length under the head is well suited to fastening most corrugated and ribbed panels to typical wood purlins and rafters.
• Polyurethane Coated Head: The coated charcoal head is painted to closely match many metal roofing colors, improving final appearance on corrugated roofs.
• T17 Type Point: The sharp T17 self starting/tapping point drives through metal panels quickly and reduces the need for predrilling in many cases.

Who It's For

These screws suit homeowners, DIYers and professional roofers installing or repairing metal roofing on houses, porches, sheds, pole barns or small agricultural buildings. They are a good fit when a visible fastener should match roof color and when a reliable EPDM washer is desired to help prevent leaks.

Those who should look elsewhere include jobs requiring stainless steel fasteners for marine environments or installations into metal substructures where specialized self-drilling points or longer lengths are needed. If absolute rust immunity is required, consider a stainless alternative rather than a galvanized fastener.

Pros & Cons

Pros

• Good finishing appearance from the painted polyurethane coated head for better curb appeal.
• Solid sealing from the ~9/16in EPDM washer to reduce water penetration around the head.
• Thicker.242in (#14) shaft and sharp T17 point provide strong hold and quick drive-in performance.
• Galvanized finish offers baseline corrosion resistance for typical roofing use.

Cons

• Some customers report mixed results on self-tapping ability and long-term rust prevention, so performance may vary by environment and metal thickness.

Our Verdict

For routine metal roofing work on wood structures these #14 roofing screws offer a balance of appearance, sealing and holding power at a good value. They are recommended for most residential and light commercial roofing repairs or installs where a painted head and EPDM seal are important; however, for highly corrosive coastal sites or specialized metal substrates, consider stainless or purpose-built self-drillers.

Frequently Asked Questions

Are these screws suitable for corrugated roofing?
Yes, the painted head and EPDM washer are designed for corrugated and ribbed metal roofing and the 1-1/2in length works with typical wood purlins.

Do they require predrilling?
The sharp T17 point is self starting for many common roof panels into wood, though very thick metal or steel substructures may still need predrilling.

Will the painted heads match all roof colors?
The polyurethane coated head is painted to closely match many brands, but color may vary and exact match is not guaranteed.
