- Your tile roof will act as an insulator for
your attic.
- If properly installed, tile is a permanent
roof.
- Tile can now be installed to meet 110 mph
uplift requirements of the
new code.
In most cases this only requires
2 screws
in perimeter tile and one screw
in field
tiles.
- Tile weighs about 1000 pounds per square
and may require reinforcement
to your roof
structure.
- Tile comes in 3 profiles and quite a number
of sizes according to the manufacturer.
- Tile comes in both cement and clay forms.
There are some clay tile roofs
which have
been in place for some 400
years.
- Clay tiles are molded and then baked.
They are fragile like ceramics.
- Most cement or concrete tiles are extruded.
They are much more uniform
than clay and
will lay with variable laps.
- Clay tiles are interlocking, which means
that one bottom corner and
the opposing top
corner are cut off from each
tile.
This gives the clay tiles more
chance to
leak than the cement tiles.
- All cement is porous.. This includes
cement tiles. That means
that in a
given period of time the tiles
will absorb
water.
- Tile manufacturers used to sell tile with
a slurry coat and color as
superior to those
which had no slurry coat, because
the slurry
coat slowed the penetration
of water.
- Today some manufacturers sell tile with oxide
added in the cement as being
premium because
they say the color is all the
way thru the
tile and will not go away.
They mark
this tile up and push it because
it gives
extra profit.
- Other manufacturers only charge the extra
which it costs for the oxide
for the color
thru tile.
- None of the manufacturers will tell you that
adding oxide to the tile weakens
the mix
and makes the tile difficult
if not impossible
for people to walk on.
- I have no clue and they probably don't either
as to how the added oxide will
affect the
life of the cement.
