Replacing the metal siding panels on the exterior of a mobile home is accomplishable but the trick is to find the metal panels that match the previous metal siding. You can order the panels or even have a metal shop fabricate the metal siding panels for you. Home improvement centres are capable of ordering your matching metal panels as well. The new panels will not have the weathered look like the old panel but the pattern on the metal is the same.

  1. 1

    Remove all of the sheet metal screws on the metal siding panels that you are replacing, using a power drill and a ¼-inch nut driver. Loosen the metal panels, on each side, of the siding panel. This will provide you adequate room to remove the panels that you are replacing. There will be approximately 15 screws for each metal siding panel. Save the screws for the installation of the new metal panels.

  2. 2

    Push the old siding panel to the left side. Repeat this for all panels that you are replacing. This will unlock the two panels from each other, allowing you to remove the piece of siding from the exterior of the mobile home. Be sure to wear gloves, as the metal edges can be very sharp.

  3. 3

    Check the framing that is behind the siding panels to ensure there is no rotten wood, and that the insulation is dry and intact. Replace any rotten wood or wet insulation before installing the new siding.

  4. 4

    Measure the metal siding panels attached to the mobile home, and ensure the new siding panels are the same size as the old panels. Measure the old panels as well. This will ensure that the top and bottom of the metal panels are even. Use a pair of tin snips to make any necessary cuts to the metal panels.

  5. 5

    Install the new siding panel by hooking the locking seams to the old existing siding panels. Lock the seams by aligning the two sides of the panels with the two seams on the old panels, and slide the new panel upwards, towards the roof until the panels are even with each other.

  6. 6

    Use a mason string line or twine, and align the string with the screws on the other siding panels. Make a mark on the new panel where the screws will need to be. This will ensure that all the screws are even with all of the other screws on the exterior of the mobile home.

  7. 7

    Refasten the sheet metal screws to the new metal siding panel starting at the bottom of the panels seams, and working upward to the top of the siding. Do not over tighten the screws, as this will result in denting the new metal.
