High pressure hydro wash
roof thoroughly
to remove any loose paint, bird droppings
and any other dirt.
* Please note that we do not remove all the
old paint. Gutters to be cleaned of all loose paint, leaves,
etc. All valleys are to be inspected and cleaned.
Blocked valleys are a common cause of roof leaks. All
Flashings are to be inspected, and
where necessary sealed with a latex
compound or a fiberglass membrane. This is another common
cause of roof leaks
The roof is inspected for
chipped and
broken tiles, which are replaced or repaired.
Broken tiles are a common cause of roof
leaks
* Please note we replace up to 20 tiles
free of charge Often the existing make of roof tile is no
longer available. In this case we will take tiles from the
gutter line and replace the broken tile with a good one,
then we will repair the broken tile and put in back in the
gutter line.
When using tiles with more grit than the
others there will be a matt/gloss type finish All cracking
and loose mortar is removed
from the ridging.
This cracking of the existing mortar is
caused by the inability of cement to absorb
thermal movement. This is another common cause of roof leaks
as can be seen here
All ridging is repaired
and sealed with
a patching compound called TOP PATCH
This product is specially formulated for TOPCOAT. The
advantage of TOP PATCH is its outstanding thermal
properties. It absorbs thermal movement easily. It is a
great substitute for conventional cement. Shown here is a
airless roof spraying
machine. These spraying machines do not allow any air to mix
with the coating being sprayed. This is vitally important,
if you get air in your coating, it will form bubbles that
will pop and cause peeling.
After all the preparation, a
sealer coat is
applied to the roof. Please note that in most cases our
sealer coat is mixed with our first coat of coating. This
allows for good colour penetration into the roof tile.
The second coat of Acrylic
roof coating
is applied by airless spray gun. The final coat of Acrylic
roof coating is applied by airless spray gun. * Please note
that in some cases "mapping" may occur. Mapping is when your
have either a change in texture or level caused normally by
thick old paint which we cannot always remove or from lack
of grit
on the substrate. This normally results in a matt then gloss
type finish. Unfortunately there is not much we can do about
this.
