Understanding Roofing Tin Screws
What are Roofing Tin Screws?
Roofing tin screws are specialized fasteners designed for metal roofing applications. They come with sharp tips that allow them to drill into metal surfaces without pre-drilling, saving time and ensuring a secure fit. Their construction often includes corrosion-resistant materials, making them suitable for various weather conditions.
Types of Roofing Tin Screws
Self-Drilling Screws
These screws have a drill-shaped tip that allows them to penetrate metal without pre-drilling. They are commonly used for securing metal roofing panels to steel or wood framing. The EPDM rubber washer provides a waterproof seal, preventing leaks.
Self-Tapping Screws
Self-tapping screws create their own hole as they are driven into the material. They are often used for attaching metal sheets to wooden structures. Unlike self-drilling screws, they may require a pilot hole for optimal installation.
Exposed Fastener Screws
Exposed fastener screws are used in applications where the screw head will be visible. These screws are designed for corrugated metal roofing panels and typically feature a rubber washer for water resistance.
Concealed Fastener Screws
Concealed fastener screws are used in applications where the screw head is hidden from view. This type of screw is ideal for providing a seamless appearance on metal roofs, enhancing both aesthetics and performance.
Wood to Metal Screws
These screws are designed to secure metal roofing to wooden framing. They are often zinc-plated to prevent rust and corrosion, making them suitable for various environments.
Factors to Consider When Choosing Roofing Tin Screws
Material Compatibility
Ensure that the screws you choose are compatible with the materials used in your roofing system. Stainless steel screws are ideal for harsh environments due to their corrosion resistance, while coated steel screws offer a balance of durability and cost-effectiveness.
Corrosion Resistance
The longevity of your roofing system can be greatly affected by the screws’ resistance to rust and corrosion. Look for screws with protective coatings or made from stainless steel to ensure they withstand the elements.
Washer Quality
The quality of the washer can impact the effectiveness of the seal. Opt for screws with high-quality EPDM washers, which provide excellent waterproofing and durability.

| Corrosion Resistance | High | Moderate | High | High | Moderate |
| Washer Type | EPDM | None | EPDM | EPDM | None |
| Installation Speed | Fast | Moderate | Fast | Moderate | Slow |
| Cost | Higher | Lower | Moderate | Higher | Lower |
Installation Tips for Roofing Tin Screws
Tools Needed
To install roofing tin screws, you’ll need a power drill, a torque wrench, and safety equipment such as gloves and goggles. Ensure your drill is set to the appropriate torque to avoid over-tightening and damaging the screws or roofing material.
Pre-Installation Steps
Before installation, inspect your roofing panels and framing for any damage or defects. Proper alignment of the panels is crucial to ensure a secure fit and optimal performance.
Installation Process
- Align Panels: Start by aligning the roofing panels properly to avoid misalignment.
- Drill Pilot Holes: For self-tapping screws, drill pilot holes if necessary to guide the screws.
- Insert Screws: Begin inserting screws at the designated points, ensuring they penetrate the material deeply enough to create a secure connection.
- Check Seals: After installation, check the seals around each screw to ensure they are watertight.
Post-Installation Inspection
Once the screws are installed, conduct a thorough inspection to ensure that all screws are secured and that there are no gaps or leaks around the washers. Regular maintenance checks can help prolong the life of your roofing system.

FAQ
What are roofing tin screws?
Roofing tin screws are fasteners designed specifically for securing metal roofing panels to underlying structures. They feature sharp tips for easy penetration and often include washers to create a watertight seal.
What types of roofing screws are available?
The main types include self-drilling screws, self-tapping screws, exposed fastener screws, concealed fastener screws, and wood to metal screws, each serving different applications and material compatibilities.
Why is corrosion resistance important for roofing screws?
Corrosion resistance is crucial for the longevity of roofing screws as it prevents rust and deterioration, which can compromise the integrity of the roofing system over time.
How do I choose the right roofing screws for my project?
Consider factors such as material compatibility, corrosion resistance, washer quality, and the specific application of the screws. Consulting product specifications can also provide guidance.
Can I install roofing screws myself?
Yes, with the right tools and knowledge, you can install roofing screws yourself. Ensure you follow proper installation techniques and safety precautions.
What is the difference between self-drilling and self-tapping screws?
Self-drilling screws have a drill-shaped tip that allows them to penetrate materials without pre-drilling, while self-tapping screws create their own hole but may require a pilot hole for optimal installation.
How do I maintain my roofing screws after installation?
Regularly inspect screws for signs of corrosion or loosening and check the seals around washers to ensure they remain watertight.
What should I do if a screw becomes loose?
If a screw becomes loose, tighten it carefully to avoid damaging the roofing material. If the seal is compromised, consider replacing the screw and washer.
Are concealed fastener screws better than exposed fastener screws?
Concealed fastener screws provide a cleaner appearance and can enhance the longevity of the roof by reducing exposure to the elements. However, exposed fastener screws may be easier to install and are often used in certain applications.
Where can I buy roofing tin screws?
Roofing tin screws can be purchased from various retailers, including www.lowes.com, www.walmart.com, and specialized suppliers like www.teksscrews.com and allpointsfasteners.com.
