Quality Metal Roofing Screws
What Are Metal Roofing Fasteners and Metal Roofing Screws?
Metal fasteners are designed to serve a broad spectrum of purposes and come in an extensive array of standardized shapes, sizes, and materials.
Metal roofing screws are fasteners specifically made for use in installing metal roof panels. The world of metal roofing is diverse, with different types of panels requiring specific screws for optimal performance. Metal roofing screws typically find their construction in materials such as stainless steel or carbon steel, chosen for their durability and resilience.
They offer a range of features, making them versatile and adaptable to the demands of various metal roofing applications. These elements include various available drill points for different panel types, coatings for corrosion resistance, bonded or non-bonded EPDM rubber washers to prevent leaks, distinct shank diameters, and varying thread patterns.
You Need the Best Metal Roofing Supplies
Ill-suited fasteners or roofing screws can lead to subpar performance, corrosion issues, and potential damage to your roofing. In some regions, particularly those with high salt content in the air, like coastal areas, specialty corrosion-resistant screws may be necessary. Stainless steel screws, for instance, are often recommended in such environments. However, it’s important to note that they cannot penetrate metal roofing panels independently and require pre-drilling.
Let’s take a look at some specialized types of metal roofing screws:
Cap Screws
Corrosion-resistant cap screws, like the ProZ Aluminum Cap and the ProCap Stainless Steel Cap, combine a carbon steel shank with a cap made of either a zinc-aluminum alloy or stainless steel, resulting in high corrosion resistance in the exposed portion of the fastener. An advantageous feature of these screws is that they do not necessitate pre-drilling, simplifying the installation process.
EPDM Washers
Another feature of metal roofing fasteners is the inclusion of a rubber washer. EPDM washers, renowned for their superior weather resistance, outshine the competition regarding UV exposure. While no rubber or plastic is immune to UV degradation, EPDM performs admirably even under harsh conditions. Nevertheless, it’s worth noting that EPDM washers can deteriorate over time, particularly in regions with intense UV exposure and other corrosive factors.
In an area with higher UV exposure as well as other corrosive elements such as air salinity, it is always better to use a screw that completely covers the washer. While these screws tend to be slightly more expensive than bonded washer screws, it would be far more costly to go back and replace screws later due to degrading washers.
Replacement Screws
Although replacement screws were initially used for replacing failing nails used to install metal roofing, replacement screws now serve a number of purposes. Most fasteners utilize a ½” bonded washer, but some, like the ReGrip, use the larger 5/8″ washer for better coverage and corrosion protection. These screws can be used for installing metal panels or attaching accessories like snow retention.
Hi-Lo Fasteners
Commonly found on screws employed in metal-to-wood installations, hi-lo fasteners boast a unique design with two distinct thread types. The hi-thread creates a deeper cut into the panel, while the low thread minimizes the production of shavings. This results in reduced driving torque requirements, improved pull-out strength, and a reduced risk of cracking during installation.
