Galvanized Roofing Nails for Asphalt Shingles 

Galvanized wide-head roofing nails are the safest and most reliable method of mechanical fastening for asphalt shingles. They are specially designed to provide high wind resistance, thermal durability, and long-term performance, fully aligned with IKO’s technical specifications.

Choosing the correct type of nails is critical, as it ensures each shingle's stability, prevents future detachment, and significantly extends the roof's lifespan. Their wide, galvanized heads prevent tearing and ensure strong holding power even in demanding weather conditions.

Technical Specifications

• Type: Galvanized wide-head roofing nails

• Suitable for: IKO asphalt shingles & all types of roofing shingles

• Head Diameter: Ø 9 mm

• Length: 20 mm (2 cm)

• Consumption: ~1 kg per 18–20 m² of roof surface

• Durability: High corrosion resistance due to galvanization

Installation Guidelines (According to IKO Standards)

Proper nail placement is essential for optimal roof performance and longevity.

1. Nail Positioning

• Nails should be placed 1.5–2 cm above the cut-out (notch) of each shingle.

• For edge shingles, maintain a 2.5 cm distance from the sides.

• Always drive the nail straight and perpendicular, never at an angle.

2. Nail Depth

• The nail head must sit flush against the shingle surface without cutting into it.

• Do not overdrive the nails — if driven too deep, the holding strength is reduced.

3. Number of Nails

• 4 nails per shingle for standard applications.

• 6 nails per shingle in high-wind areas or when following IKO’s High Wind Application instructions.

4. Nailing Surface

• Always fasten shingles onto a solid wooden deck (e.g., OSB or plywood).

• Avoid loose or spaced boards, as they reduce fastening strength.

5. Avoid Incorrect Fasteners

• Do not use woodworking nails, screws, staples, or non-galvanized nails —
  these significantly shorten roof lifespan and may cause rust or shingle failure.

Advantages of Using IKO Galvanized Wide-Head Nails

• Excellent corrosion resistance

• Ideal compatibility with all asphalt shingle types

• Enhanced protection against wind uplift

• Long-term structural stability and fastening reliability

• Strong hold without damaging the shingle surface
