There are a few important qualities to be considering when it comes to screws for any metal roofing need you may have, and the head type you utilize is definitely on this list. There are a wide range of different screw head types that may be applicable or useful within metal roofing projects, and knowing the proper selection for your needs is important.Â
At Supply Maverick, a division of Mid Michigan Metal Sales, we're proud to offer a wide range of metal roof fasteners that includes screws, hammer tackers, trim nails and numerous other options for clients all around the US and Canada. Our screws come with several head type options, including pancake screws, wafer head screws and more. Here's a basic look at the most notable kinds of metal roof screws you might consider for your needs, plus what to think about for each of them.Â
One of the most popular and well-known screws for metal roofs in particular, largely due to its flat head and relatively low profile, is the pancake screw. These screws are available in both galvanized and stainless steel options, plus they also come with sealing washers that will prevent leaks and rust over time due to exposure to moisture from the elements.
The pancake head design itself is what makes these screws so beneficial for metal roofing projects. They're designed to create a strong connection between the roof panel and underlying structure, all while keeping both sides flush and even. They also have a larger bearing area than other screw types, helping to distribute evenly across the panels and prevent any damage.
Similar to pancake screws are wafer head screws, which offer many of the same benefits with slight variations. These heads are slightly raised in comparison to pancake screws, with a slight rounding that comes off as a dome-like shape. This head type is better suited for thinner, more lightweight metals and roofing materials, plus they offer the same leakage protection qualities that pancake screws do.
One additional benefit of wafer head screws compared to some others: They're self-drilling, meaning you won't need to pre-drill holes before using them. This can save significant time and effort during installation.
For those in need of screws that offer more torque resistance due to thicker or heavier roofing materials, hex head screws are an excellent option. These screws have a larger bearing surface than any other screw type on this list, allowing them to better distribute weight across the panels and prevent damage.
One potential downside here is that hex head screws may be more difficult to install by hand, as they require a wrench or drill with a socket attachment. On the flip side, this also means they'll provide better security and hold over time.
For those who require a flush, low-profile connection between roof panels and the underlying structure, flat head screws are a great choice. These screws have a completely flat top that will not rise above the surface of the roofing material, making them perfect for projects where aesthetics are important.
One thing to consider with flat head screws is their size - they may be smaller than other types and thus require more precise installation techniques. Be sure to carefully measure and plan before using these screws.
For those who do not require any specific benefits like torque resistance or flatness, round head screws are a simple but effective option. They have a standard rounded top that will slightly protrude above the roofing material surface, all while still providing a strong connection between panels.
For low-profile needs, and particularly if you want a screw that works for both Phillips and square drive tools, pan head screws are a good choice. These have a slightly raised top with rounded edges and offer many of the same benefits as pancake screws.
