Roofing fasteners and accessories
Rooftop installation demands unrelenting strength, and SFS delivers every time. Each fastener is engineered from premium materials, tested to the highest standards, and emboldened by ongoing innovation to ensure unmatched performance and reliability that lasts. Partner with SFS for industry expertise, reliable delivery, and unmatched roofing fastener performance.
Innovations that Move Roofing Projects Forward
Deadlines are tight, project specs are demanding, and delivering exceptional results is essential. That’s why SFS engineers fastening solutions that streamline workflow and stand up to the toughest jobsite challenges. Every new innovation and purpose-built product line is rigorously tested and refined to help you build faster, build better, and achieve results that surpass expectations.

Isoweld: smarter attachment for single ply roofing
Isoweld® is SFS’s advanced induction welding system for low slope commercial roofing, engineered to securely attach TPO and PVC/KEE membranes without penetrating the membrane. By welding membrane overlaps directly to the fastener plates, isoweld delivers reliable bonds and consistent installs. Designed for user agility and straightforward operation, isoweld® offers simple calibration, real-time verification, and numerous other features to enhance both speed and accuracy.
Dekfast: built for flat roofing confidence
Dekfast fasteners are built for the realities of commercial low slope roofing, offering high pull-out strength and stable drive heads for efficient installation. Each roofing fastener leverages the strength of either carbon steel or 410 stainless steel, with many featuring a protective cathodic epoxy coating for added durability. At SFS, we have carefully considered every facet of Dekfast roofing fasteners to improve installation speed and reinforce performance, making Dekfast one of the most trusted choices for commercial low slope roofing.
Woodgrip: fastening metal to wood with precision

SFS designed Woodgrip fasteners specifically for attaching metal panels to wood in roofing and cladding applications, delivering reliable connections on post-frame and standing seam roofs. The innovative Woodgrip+ thread and point design pierce multiple metal layers quickly and cleanly, eliminating the need for pre-drilling and leaving no debris behind. With a variety of head, washer, and VistaCoat® premium coating options, Woodgrip roofing fasteners deliver weathertight security and superior corrosion resistance.
ZAC fasteners: lasting rust-resistance
Every inch and every angle of the ZAC® screws was engineered for peak speed, strength, and long-term performance. The roofing screw’s zinc alloy cap head eliminates red rust while protecting the integrity of the connection. When pairing this capped head style with a sharp point and aggressive threads, it makes for the perfect combination of a fast installation and long term reliability. In the end you can feel confident that our ZAC® fasteners will help keep your roof panels secure under demanding conditions.
Simply put, innovating new fasteners and metal roof clips is what we do best! Our roofing screws are meticulously crafted from high-quality steels, with many featuring zinc alloys for superior corrosion resistance and the assurance of a limited long-life fastener warranty. The hex head design on many of our pitched roofing fasteners guarantees stability during driving, while precision cold-forged points deliver swift, reliable installations—key for demanding commercial builds. Backed by rigorous engineering, a global logistics network, and hands-on support from selection to delivery, SFS ensures unmatched quality and accountability at every step
If you are feeling unsure about which SFS roofing clip to select, we encourage you to utilize our panel clip finder tool which will help guide you to the SFS product depending on factors like your panel manufacturer, machine type, panel type, and more. Further more, to help specifiers identify the optimal standing seam roof clip, we created an SFS Buying Guide to different types of metal roof and panels clips.
Additional reading that can further assist include standing seam comparisons: snap lock vs mechanically seamed roofing, and How to replace metal roof screws.
Choosing between carbon steel and stainless steel roofing screws depends on the project’s environmental conditions, durability needs, and budget constraints.
Carbon steel metal roofing screws offer superior hardness and clamping load capacities while also being cost-effective. However, they are more susceptible to rust. To counter this, SFS designed many of our carbon steel metal roofing screws to come with a zinc-capped head to enhance corrosion resistance.
Still, 304 stainless steel roofing screws may be the superior choice for projects taking place in areas with higher exposure to corrosive factors, such as coastal regions or areas with elevated pollution. For more guidance, read 300 vs 400 stainless steel, or consult with a member of the SFS customer success team.Â
Our standard paint colors can be viewed in our VistaCoat color chart, but our paint-match services go far beyond the 48 colors you see represented here. We have already identified thousands of panel manufacturer shades and created a fastener color code for each, making the color selection process seamless. Simply use our Color Selector Tool to select your panel manufacturer & color to see the SFS recommended shade.
