Metal Roofing Should Be Fastened With A Screw Gun And Not An Impact Gun Or Drill. EASY Metal Roofing Installation Video That Covers Using The Correct Tools To Install A Metal Roof, Drill Speed Settings, And Screw Gun Types.
Using an impact gun to screw down your metal roofing panels is the single biggest cause of screw failures. Use an actual screw gun with an adjustable clutch, variable speeds, and a depth sensing control feature. A screw gun allows you to adjust the screw torque and drill speed settings.

Use A Screw Gun To Fasten Metal Roofing Screws
Using the right tools is an essential step to prevent maintenance issues and roof failures. You must fit the tool to the fastener. You need an actual screw gun and not a drill or an impact driver.
When you use a drill and let go of the trigger it does not disengage. You have to release the trigger at the correct moment or the screws will be over driven, damaging the washers and possibly the panels. Using an Impact gun to fasten screws is the single biggest cause of screw failures.
In addition, you can under-drive the fasteners which will create a leak point. A drill or an impact gun could work, but unless you have a lot of experience you are likely to incorrectly tighten the fastener. Using a real screw gun such as the Dewalt DW266, DW267, DW268 or the Milwaukee 6780-20 and 6790-20 lessens this possibility.
What type of screw gun should I use to fasten metal roofing panels?
Use an actual screw gun with an adjustable clutch and a depth sensing control feature. Screw guns are designed so that you can adjust the torque which will help eliminate over tightening of the screws. In addition, use a variable speed screw gun which will permit you to change the speed.
Match the speed of the drill to the substrate or screw type
Use a 2,500 RPM screw gun for wood and steel substrates that are less than 1/4-inch thick
Use a 2,000 RPM screw gun for steel substrates that are 1/4-inch thick and heavier
Use a 1,000 RPM to 2,000 RPM screw gun for 304 stainless steel screws
