Production Procedure for Tiled Roofs
Tiled roof damp proofing process and painting process
High pressure hydro wash roof thoroughly to remove any loose paint, bird droppings and any other dirt from the tiled roof before the painting process or damp proofing process begins.
Before the tiled roofs can be re-painted or sealed, gutters need to be cleaned of all loose paint, leaves, etc. to ensure paints and damp proofing is applied to a clean surface.
All valleys on the tiled roof are inspected and cleaned out. Blocked valleys are a common cause of roof leaks.
All flashings are to be inspected and cleaned and where necessary sealed with either a latex compound or a fibre glass membrane. This is another common cause of roof leaks.
The tiled roof is inspected for chipped and broken tiles, which are replaced or repaired. Broken tiles are a common cause of roof leaks. *Please note that 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 it back in the gutter line.
Tiled roof ridging inspection: 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.
All ridging is repaired and sealed with a patching compound. The advantage of this patching compound is its outstanding thermal properties. It absorbs thermal movement easily. It is a great substitute for conventional cement.
This is an 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 first coat of acrylic roof coating is applied by airless spray gun or by hand (roller or brush) depending on the size of the project.
Painting by airless spray gun is recommended for bigger projects, where there is a time deadline. However, hand painting is recommended for smaller projects using the hand brush or roller.
The final product after second coat of Acrylic roof coating is applied by airless spray gun or by hand.
