These roofing screws are fitted with a washer, ensuring the screw will fit snugly against the roofing sheet, allowing for maximum fixing and a water tight seal.

Roof Zip 12 gauge x 50mm Class 4 Tek roofing screws for fixing into timber or steel. 

Winds can create considerable forces on both the upper surface and the underside of metal roofs. To ensure roofs are secure, our 12 x 50 Class 4 screws are recommended for fixing pierced metal sheeting to timber or metal battens. Self-drilling hex head fasteners with neoprene sealing washers are manufactured from high tensile steel with Colorbond durable coatings.  Roofing screws should be driven through the square with the surface of the sheeting to provide a complete seal around the screw hole.   

Please do not over-tighten the Tek screws, as this can damage the sealing washer and roof sheeting. The ends of corrugated roofing and close-pitched trapezoidal roofing sheets should be fixed through the side lap and every second crest after that.

Fixings are intermediate purlins or battens, for corrugated metal roofing should be through the side lap and the third and seventh corrugation from the side lap. For close-pitch trapezoidal roofing sheets, fixings should be at every third rib.

A string line should be used to make out a straight line along the centre of the battens or purlins.

Introduction to Roofing

Roofing is a crucial aspect of building construction, providing protection from the elements and ensuring the structural integrity of a property. When it comes to roofing, the type of screws used can make a significant difference in the overall quality and durability of the roof. Along with the right roofing tools, roofing screws are designed to secure roof sheeting, such as metal roof panels, to metal battens or timber, providing a strong and weather-tight connection. In this section, we will explore the importance of roofing screws and their role in ensuring a secure and long-lasting roof.

Types of Roofing Screws

There are various types of roofing screws available, each designed for specific applications and materials. Some common types of roofing screws include:

• Self-drilling screws: These screws are designed for use with metal roof sheeting and can drill directly into the metal without the need for pre-drilling.

• Hex head screws: These screws have a hexagonal head and are commonly used for roofing applications.

• Colorbond roof screws: These screws are specifically designed for use with Colorbond roof sheeting and are available in a range of lengths and gauges.

• Cladding fasteners: These screws are used for securing cladding materials, such as metal or timber, to the building frame.

When choosing the right type of roofing screw, it’s essential to consider the type of roof sheeting, metal battens, and other materials being used. By selecting the correct screw for the job, you can ensure a secure and long-lasting connection.

Installation Best Practices

To ensure a secure and long-lasting roof, it’s essential to follow best practices when installing roofing screws. Some tips to keep in mind include:

• Always use the correct type of screw for the job, taking into account the type of roof sheeting, metal battens, and other materials being used.

• Use a hex head screwdriver or impact driver to drive the screws, and avoid over-tightening, which can damage the screw or surrounding material.

• Ensure the screw is driven straight and level, and that the head is seated properly on the underside of the roof sheeting.

• Use neoprene seals or rubber washers to provide a weather-tight connection and prevent water ingress.

• Consider using screws with a reverse thread on the underside of the head for a better join and increased security.

By following these best practices and using high-quality roofing screws, you can ensure a secure and long-lasting roof that will withstand the elements and provide years of trouble-free service.
