What are Roofing Screws?

Roofing screws are specialised drilling & tapping fasteners designed to secure roofing materials to a structure. They include rubber-backed washers, which provide a watertight seal when fastened making them ideal for applications where moisture resistance is critical.

Typically made with a sharp, pointed tip, these screws can pierce through a variety of sheet roofing materials, including metal, polycarbonate and wood.

The threading on roofing screws is engineered to provide maximum grip and stability, while the washer help to ensure a secure hold against wind uplift and other environmental stresses.

How Metal Roofing Screws Work

Metal roofing screws are indispensable in a wide range of applications, from shed roofing to industrial warehouse projects. They are designed to effectively secure metal roofing panels, corrugated iron sheets, and polycarbonate roofing materials to the framework.

When installed, corrugated roofing screws penetrate the roofing material and substrate, anchoring securely to provide robust structural integrity. The rubber washers on these screws compress upon installation, creating a seal that prevents water ingress. This feature is especially important in environments exposed to heavy rain or extreme weather conditions, as it helps prevent leaks and maintains the roofing system's longevity.

What Material Self-Tapping Roofing Screws Are Made From

Our self-tapping roofing screws with rubber washers are primarily manufactured from A2 Stainless Steel, a material known for its exceptional corrosion resistance and durability.

A2 Stainless Steel roofing screws are particularly advantageous in outdoor or industrial environments where exposure to the elements is common. This material choice ensures that our metal roofing screws maintain their structural integrity and appearance over time, even in challenging conditions.

This material allows our range to be used with a multitude of materials in mind including polycarbonate roofing screws.

Size and Type Roofing Sheet Screws Available

Our range of roofing screws for corrugated iron sheets comes in a variety of sizes and types to suit different roofing materials and installation requirements.

The lengths of our roofing sheet screws range from 19mm to 300mm, catering to both lightweight and heavy-duty applications. In addition, we also offer a variety of head types, including countersunk and hex bolt, coupled with drive types such as Pozi, Torx and hex head, allowing for compatibility with various tools and installation requirements.

If you can't find the exact roofing screws with washers here, our selection of precision components also includes individual sealing washers in a greater range of sizes along with self-tapping screws, which can be combined to create any combination of drive type, head type and washer size you need.

FAQs

Q: Do you need to pre-drill for roofing screws?

A: Depending on the thickness and hardness of the roofing material, pre-drilling is not always necessary. These screws are designed to drill their own threads, making installation easier and quicker. However, for thicker or harder materials, pre-drilling can help ensure a smoother installation and a more secure fit.

Q: What size roofing screws should I use?

A: The size of roofing screws you need depends on the material you're securing and the thickness of the substrate. Our roofing screws range from 19mm to 300mm in length. For lightweight materials like polycarbonate roofing, shorter screws are typically sufficient, while longer screws are recommended for securing metal panels to thicker substrates.

Q: Are roofing screws self-tapping?

A: Yes, our roofing screws are self-tapping. These screws have a sharp point and specially designed threads that allow them to cut their own threads as they are driven into the material. This feature eliminates the need for tapping threads and ensures a tight, secure fit.

Q: Do roofing screws leak?

A: Roofing screws are designed to prevent leaks, especially when equipped with integrated washers or rubber washers. The washers compress upon installation, creating a watertight seal that helps prevent moisture from penetrating the roofing material. Proper installation is crucial to ensure that the screws do not leak, so it's important to make sure the material is free of debris and that you install on a relatively flat section to allow the washer to form a seal.
