Bend Your Own Metal Flashing For a DIY Sunroom Or Sunroom Repair

Bending metal flashing involves using a metal brake to bend sheet metal. You can use this if you are building your own sunroom or repairing a sunroom. Poor flashing will result in leaks and that is the last thing you want in your home! Often times when we get sunroom repair calls it is because whoever installed the sunroom did not flash the room properly.


Gather the necessary tools: You will need a metal brake (Tapco Pro 19 Metal Brake)or a bending tool specifically designed for sheet metal, a tape measure, a straight edge, and a marker.

Measure and mark: Use a tape measure to determine the length and width of the metal flashing you need. This will vary based on your project size. Mark the measurements on the metal with a marker.

Set up the bending tool: If you have a metal brake, adjust it according to the desired angle and width of the bend. Follow the manufacturer’s instructions for your specific tool. Metal brakes aren’t cheap so if you don’t own one, you can rent one from a store like Home Depot.

Align the metal: Place the metal flashing in the bending tool or secure it in the vise/clamps, ensuring that the marked line is aligned with the bending edge.

Make the bend: Apply even pressure to the metal while bending it.

Check the angle: Once you have made the initial bend, use a straight edge or a square to check if the angle is accurate. Make adjustments if needed.

Repeat if necessary: If you need multiple bends or more complex shapes, follow the same process for each bend, ensuring proper alignment and applying even pressure.

Finishing touches: After bending the metal flashing, you can trim any excess length using tin snips or a metal-cutting tool. Smooth out any rough edges with a file or sandpaper.

Happy Home Improving!
