The frame work for the roof structure is box section 4 inch x 2 inch heavy 3.2 mm thick metal sections. There are columns at even intervals so a more extensive truss system is unnecessary (as opposed to Chok Dee #1).dozer

Hip Roof StructureThe raw hip roof structure. The key members are the 3.2 mm thick steel with intermediate sections done in the 2.0 mm thick steel. Box sections are used throughout, no C sections. dozer

Raw WeldA raw (prior to rust painting) weld. The 3.2 mm thick electrode rods are used (as opposed to the 2.6 mm variety) for a heavy duty weld. All welds should be inspected when ever possible. dozer

Wood to Support the Facia BoardWood is installed within the box sections of the roof structure to support the facia board which will be affixed. These members still to be painted after the box sections were cut. dozer

Basic Roof StructureThe basic roof structure with the battens fixed at periodic intervals to support the Cpac roof tiles. dozer

Rust Painted WeldAfter a few days of raw welds any good team will automatically paint the welds. Just a point of procedure to verify. dozer

Galvanized Sheeting for Roof ValleyMost of the problems with CPAC concrete roof tiles come from inadequate valley material or poorly done ridges. It is easy to get the wrong stuff, just go to any supply store and ask for the valley material that everyone uses. This is the 1 meter wide material, formed in the center for water run-off, roofs with this as valley material (properly installed) don't have problems. dozer

CPAC Monier Roof TilesThe CPAC Monier roof tiles being laid in place. These tiles are basically dummy proof, except at the valley and ridges. dozer

Properly Installed Bird StopThis bird stop has about the right clearance, a snug fit is required or otherwise you will get unwanted entry points. dozer
|
|
Ridges Laid in PlaceThe ridge tiles are laid in place over a waterproofed (via Sika) concrete mix. Note that the exposed concrete will still need to be treated with a exterior coat of waterproofing agent. The other method is dry tech, which is not used here. dozer

Underside of Ridge BeamThe underside of a ridge beam showing the welds and also the underside of the CPAC tiles sitting on the battens. dozer

Ceiling StructureThe C Lie suspension rails used are the heavier grade and are spaced at about 60 centimeters by 1 meter intervals. Note the tiered ceiling section on the left side (to support the two levels of ceiling structure).dozer
