Replacement ceramic tiles can be hung with straps attached to
the back of the tile. Do not use exposed strap hangers
because they make the roof look bad and they fail prematurely. The copper strap shown
below can be altered to fit almost any type of ceramic
tile, including Spanish tiles. It's a good idea to put
caulk/adhesive between the copper strap and the tile
to help adhere it into place. Use copper wire to tie
the strap to the hanger. 14 gauge single strand insulated
wire works well.
below shows the back side of the tiles and how the tile
hook holds the tile in place. Tiles are usually loose enough
on the roof that you can slide the tile and hanger in place
without any problem. The replacement tile hooks on the
existing tiles. When the job
is done, there is nothing visible on the surface
of the roof that shows a repair was made.
Valley (and general
flashing) replacement on a tile roof (see below) is similar
to valley replacement on a slate roof. The tiles must be
removed to expose the original flashing metal, the metal
must be fully removed, and then the new metal must be installed.
The tiles are refastened into their original positions.
Tile hangers (as above) are used where the tiles cannot
be nailed, and copper wires are used to hang the small
triangular pieces into the valley since you do not want
to nail through the valley metal except along the edges.
Note that each tile is numbered by scratching with a nail
before removal. This makes replacement of the tiles a
quick and accurate job.
73 year old
Ludowici Imperial tile (a flat shingle tile) at Grove
City College, Grove City, PA . We're replacing all the
original copper valleys with 26 gauge terne coated stainless
steel (above). We also rebuilt the plumbing vent pipe flashings using 4 lb. sheet lead, and reflashed
the chimneys with terne coated stainless steel (below).
