Metal Roof

Metal Roof

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. It may be necessary to use a grinder with a wire cup brush to remove rust and stubborn paint.
All roof screws are inspected and where necessary replaced with new screws. Loose roof screws are a common cause of roof leaks. Gutters to be cleaned of all loose paint, leaves, etc.

Once all loose roof screws have been replaced, each roof screw is sealed with a latex compound.
All ridge joints are to be sealed with a latex compound or a fiberglass membrane, depending on the circumstances.

Where necessary roof sheets may have to be pop riveted together. All valleys are inspected and cleaned out.

Blocked valleys are a common cause of roof leaks

All flashings and protrusions are to be inspected and cleaned and if necessary sealed with either a latex compound or a fiberglass membrane.

These loose and unsealed flashings are a common cause of roof leaks. All rusted areas must be cleaned and
treated with a rust converter. The roof is then treated with a red oxide primer, where necessary. 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.

First coat of Acrylic metal roof coating is applied by airless spray gun. Second coat of Acrylic metal roof coating
is applied by airless spray gun.

In some cases the roof we are treating is in a very bed condition, with very uneven surfaces, thick old paint, etc.
In these cases the foreman on site may decide to rather brush on the coating, this helps when you are trying hide a change in thickness.

* 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.
