Changing Damaged RV Siding
The following pictures demonstrate the procedures for a very simple sheet metal siding repair job.
Most repairs are not this simple or easy ... various windows, doors, compartments and other opening will complicate
things as will the length of the required metal sheets.
Eight foot long sheets can be handled by one or two people, but sheets of 20 or more feet in length
will require three or four helpers and great care must be taken to avoid damaging the metal as it is
This is a relatively simple rv siding metal replacement job and
will take about 5 hours to complete. The top two panels are damaged and will be replaced with new matching
First remove the two side mouldings and the top moulding if
there is one ...
... and the clearance lights. Pop off the clearance light lenses
and remove the two screws - pry up the light assembly and remove the inner light bulb assembly by turning it
1/4 turn. Some lights may have to be disconnected - this style does not ...
Remove the staples holding the rv siding metal on - depending on
the construction used, the sheet metal may be folded over and stapled from the side over the back, or from
the back over the side metal. Take care not to dent or mark the undamaged panels!
Straighten out the folded metal using a putty knife and hammer.
The putty knife is inserted behind the metal fold as a backup and the metal carefully hammered
The rv siding sheets are installed one at a time from the top
down at the factory. The lower edge of each sheet has a "lock" or folded part that allows the sheet to be
stapled at the edges and at every vertical stud in the wall. The top of the next sheet is inserted into the
lock and then that sheet is stapled on as described above. This process is repeated to the bottom of the wall
where the bottom of the last sheet is usually folded under the wall and stapled in
In order to save time, it is often possible to "pop" out a sheet
as shown here and in the photo above. Extreme care must be taken to ensure that this sheet is not creased or
marred by this operation. This allows the two damaged sheets above to be replaced without removing all the
sheets on the wall. Mark the location of the bottom of the first sheet that will be replaced, as shown by the
arrow in this picture. The replacement sheet will be stapled in this position so that it will correctly align
with the lower sheet.
The staples holding the bottom of the damaged panel are now
accessible and can be removed at this time ...

trailer ... the bottom edge of the next higher panel is marked with a line and arrow to locate it's

The new metal sheets are shipped in a crate to prevent shipping
damage. Often the crating and shipping charges are more than the cost of the metal!
The old sheet is carefully laid over the new sheet in order to
trace out the shape required and also the locations of the clearance light access holes
... to make sure everything will line up
The shape of the top curve is trimmed using tin snips
... and a hole saw is used to drill out the access holes for the
clearance lights ...
The sheet is trimmed and ready to be installed
... and then stapled into position using the arrow marks for
correct positioning ...
... the next sheet is installed, stapled into the correct
position and the lower sheet "popped" back into the lock. Clearance lights and mouldings are re-installed
using new putty tape and the decal will be applied at a later time.
