Isolate the siding to be removed and locate its furthest edge on both sides. Insert the separation tool beneath the bottom edge of the siding piece directly above the piece to be removed.

Remember that you may repair pieces of aluminum siding, such as broken places, rather than remove and replace the aluminum siding of the whole wall.

If you must remove a complete wall, begin at the top, then work your way down, removing each row through its nails and working gently to rescue the parts since they will bend if you are not cautious.

2. Separate interlocking pieces

Wiggle the tool from side to side to separate the interlocking components. Continue down the whole length of the article.

When you’re finished, use your hands to separate the bottom edge of the component. You can proceed to replace the aluminum siding from the upper lip of the piece below.

3. To replace the aluminum siding, you need to expose the nail flange

Scraps of wood should be placed beneath the top piece’s edge to expose the nail flange of the component being removed. The wood will keep the upper piece of siding in place.

Using the pry bar and hammer, carefully pry the nails holding the piece of siding in place. Take out the aluminum siding.

If needed, cut a new strip to size. Ensure the component you want to use to replace the aluminum siding is at least 3/4 inch broader than the space it intends to fill.

Using the carpenter’s square as a reference, cut the length. Alternatively, use a pencil and a tape measure to label the piece. It was cut using tin snips.

5. Line up the nail flange

Slide the new piece of siding into position, guiding it with the old pieces on each side. Align your new piece’s nail flange with the surrounding pieces on that row. Remove the wooden scraps and hammer the roofing nails into the flange holes.

Remember to follow the nail placement instructions provided by the siding manufacturer. If in doubt, insert a nail every 4 inches at the absolute least.

6. Reassemble the Interlocking Pieces

After you replace the aluminum siding, use the siding tool to assist you in reconnecting all of the interlocking parts. Hook the new piece’s bottom edge over the upper edge of the piece below. Repeat the process for the bottom edge of the piece above your aluminum siding replacement.

Aluminum siding is put in an interlocking pattern, with the upper edge of each piece having a nail flange and a lip (like a reverse, upside-down “J”) that acts as the locking mechanism for the one above.

The following piece is likewise nailed into place, but its bottom edge has a similar J-piece that locks into place with the lip on the lower piece.

These two edges click together with the lips of the “J” pieces interlocking and may be detached with a special tool obtainable at any home improvement store. A word of caution, if you want to replace the aluminum siding, always wear work gloves.
