The Best Screws for a Metal Roof
Testing Method
We tested screws from four brands: Arrow Fasteners, Fastenal, Laticrete, and Simpson. We used two common roofing materials: 36-mil EPDM and 30-mil mineral-mat fiberglass.
We ran tests with three types of fasteners: square-head slotted screws, pan-head slotted screws (also called J-slot or J-drive screws), and round-head metal roofing screws (see the photo at the top of this article).
For each type of screw, we chose a long and a short length (1¼-inch versus 2¼-inch) and a metal roofing screw head type: flat countersunk and domed countersunk. We also tested two different thread types: coarse-thread (which pulls into the surface more aggressively) and fine-thread (which pulls into the surface less aggressively).
We attached each pair of fasteners—one long and one short—to a panel of EPDM from Fastenal, which had been in our lab for more than six years, to see how well each pair held over time.
We also used the fasteners in a more traditional application: attaching fiberglass siding to a wood-frame house. We tested pairs of each fastener type in this application to see how easy they were to install—and how easy they were to remove.
To measure how well the screws pulled into the siding material, we placed each fastener pair on a piece of fiberglass siding set on a wooden stud wall in our lab. We used a dead blow mallet to drive each pair of fasteners into the siding material 5 times. We repeated this process for each fastener type and length combination.
We used a power drill to measure how easily each screw pulled out of the siding material by hand. We attached each pair of fasteners to a piece of fiberglass siding and pulled them out again and again until we could pull them out no longer.
We ran each set of tests for all three head types (flat countersunk, domed countersunk, and J-slot), all five thread types, and all four lengths on both EPDM and fiberglass.
All tests were performed by an experienced carpenter with more than 20 years of experience installing roofing materials.

Don’t Buy Before Considering These Factors
Type of Screws
When selecting the best screws for a metal roof, the type of screw is one of the most important considerations. The most common types of screws used for metal roofing are self-tapping and self-drilling. Self-tapping screws are made from hardened steel and are designed to create their own threads when inserted into a pre-drilled hole. Self-drilling screws are made from hardened steel and are designed to both drill and tap their own threads as they are drilled into the metal roof. Both types of screws will provide a secure hold, but the self-drilling screws are often considered to be the best choice for metal roofing.
Screw Diameter
The diameter of the screws is another important consideration when selecting the best screws for a metal roof. Generally speaking, larger screws have more strength and can better resist shearing forces. As such, it is recommended to use screws with a diameter of at least 1/4 inch. However, depending on the thickness and gauge of the metal roof panels, larger screws may be required.
Screw Length
The length of the screws is also important when selecting the best screws for a metal roof. Generally, the length of the screws should be equal to the thickness of the metal roof panel plus 1/8 inch. This ensures that the screw will penetrate through the metal panel and engage the underlying support. If the screws are too short, they may not provide adequate support for the panel.
Screw Coating
The type of coating on the screws is also important when selecting the best screws for a metal roof. Generally speaking, screws with a coating such as galvanized, ceramic, or stainless steel will provide better protection against corrosion. Corrosion can reduce the strength of the metal roof panel and can lead to premature failure.
What Are the Best Roofing Screws for Metal Roof?
When it comes to metal roofing, the best roofing screws to use are those that are zinc plated. These screws, also known as galvanized screws, will be the most durable and resistant to corrosion, making them a great choice for metal roofing projects. The heads of the screws should be painted the same color as the metal roofing or siding panels, to ensure an aesthetically pleasing look.
When choosing metal roofing screws, it is important to ensure that the screws are long and strong enough to hold the panels in place, as well as to withstand winds and other elements. A quality metal roofing screw should be able to hold the metal panels in place without becoming loose or corroding over time. Additionally, it is important to make sure the screws are properly installed, as improper installation can cause the metal panels to come loose and become a safety hazard.
How Long Should Screws Be for Metal Roofing?
Metal roofing requires screws that are 1 1/2-inches in length. This size is the most common size screw used for metal roofing because it provides sufficient penetration into the roofing material. The length of the screws is important because it ensures that the metal roofing is firmly secured.
If the screws are too short, it can lead to the roofing material becoming loose and causing damage. However, if the screws are too long, then they may penetrate too deeply and cause damage to the roofing material. Therefore, it is important to choose the correct size screws for metal roofing projects.
