Roofing Screws

Roofing Screw Types

Self-Drilling Tek Screws for Heavy Section Steel

Heavy-section self-drilling Tek screws are designed to drill and fasten through thicker steel sections without the need for pre-drilling. These fasteners are commonly used for structural steelwork, heavy-gauge purlins and industrial roofing applications where maximum holding power is required.

Key benefits include:

• Fast installation
• Reduced labour time
• High pull-out resistance
• Suitable for thick steel substrates

Self-Drilling Tek Screws for Light Section Steel

Light-section Tek screws are ideal for fixing roofing sheets and cladding into thin steel purlins and framing. Their self-drilling points cut quickly through lighter gauge steel, making them a popular choice for agricultural, commercial and domestic roofing projects.

Suitable for:

• Box profile roofing
• Corrugated sheets
• Steel framing systems
• Metal cladding installations

Wood-to-Metal Roofing Screws

Wood-to-metal screws are specifically designed for fixing metal roofing sheets through timber components and into steel structures. These versatile fixings provide excellent grip and are widely used in roofing and cladding applications where mixed materials are involved.

Hex Head Roofing Screws

Hex head roofing screws remain one of the most popular choices for roofing contractors due to their ease of installation and high torque transfer. Combined with sealing washers, they provide a weather-resistant fixing solution for roof sheets and cladding panels.

Countersunk Tek Screws

Countersunk self-drilling screws are designed for applications where a flush finish is required. Common uses include flashings, trims and installations where protruding heads are undesirable.

Stitching Screws

Stitching screws are used for joining overlapping metal sheets, flashings and trims. Their smaller size makes them ideal for securing sheet-to-sheet connections while maintaining a neat, professional appearance.

Common applications include:

• Side lap connections
• Ridge flashings
• Verge trims
• Metal cladding details

Coloured Screw Caps

Coloured screw caps provide an attractive finish by concealing screw heads and helping them blend with the roofing sheet colour. Available in a range of popular roofing colours, they are ideal for projects where appearance is just as important as performance.

How to Choose the Right Roofing Screw

Choosing the correct roofing screw depends on several factors:

What Are You Fixing Into?

• Light gauge steel → Light-section Tek screws
• Heavy steel sections → Heavy-section Tek screws
• Timber purlins → Roofing screws for timber
• Sheet overlaps → Stitching screws

What Finish Do You Need?

• Hex head screws for general roofing installations
• Countersunk screws where a flush finish is required
• Coloured caps for a neat appearance

Environmental Conditions

For coastal, agricultural or exposed environments, consider corrosion-resistant coatings and finishes to maximise service life.
