Installing Metal Roof Screws

With the evolution of better materials used in metal roofing, it’s no wonder that it is becoming far more common in construction. Various coatings and color options, a longer lifespan, and lower maintenance costs have made metal roofs hugely popular in recent years. No longer are metal roofs used mainly in commercial buildings. Now, they are becoming a popular choice in homes as well.

If you are installing metal roofing yourself, here are some simple steps to doing it right.

Instructions:

Step 1; All roofing screws are self-tapping. Just below the colored head, which should match the metal roof, is a large metal washer. Below that is a thick rubber grommet or rubber seal. If the screws do not have a metal washer or rubber seal, do not install these screws. Without the metal and rubber sealant system, the screw will cause the roof to leak.

Step 2; Using a socket driver put your socket into the chuck of the electric drive fastener or drill. These sockets are usually magnetized to hold the head of the metal screw in place while driving it through the metal roof and into the wooden framing member below.

Step 3; Install the roofing screws though the high ridges or on top of the corrugations only. This allows the water to run off and down the lower portions of the roof system. Installing a roofing screw in a lower portion of the metal roof may cause a leak in heavy rains, even with the rubber seal.

Step 4; Start the screw by pressing the drill bit firmly against the metal roof, above the wooden roof framing. Press the drill button and slowly begin the rotation of the roof screw. As the metal begins to “drill” out the roof material, speed the drill up until the screw penetrates the metal. Keep advancing the screw until the metal washer seats firmly against the metal roof and the rubber seal squeezes slightly from under all sides of the metal washer.
