[94]OIL CANNING ON METAL ROOFS |
|
OIL CANNING MAY BE A DEFECT IN THE RAW MATERIALS, OR A DEFECT IN THE MANUFACTURING PROCESS. TRISTAR MANUFACTURERS AND INSTALLS SNAPLOCK METAL ROOFING TO THE HIGHEST STANDARD.IT'S NOT ALWAYS ABOUT THE COST: IT'S WHOSE DOING THE JOB.
|
|
 |
NEW CONSTRUCTION IN SOUTH LANGLEY. I OBSERVED MY COMPETITORS WORK, WHILE DOING A GUTTER ESTIMATE, FEB 4/2015.
|
|
|
 |
THE DOWN SIDE OF THE WIDER PANEL IS THE RISK OF[OIL CANNING] OR BUCKLING IN THE HEAT. A NARROWER PANEL MAY HAVE LAID FLATTER DURING EXPANSION AND CONTRACTION.
|
|
|
 |
THESE ARE 18" WIDE STANDING SEAM PANELS -USING HEAVIER 24 GAUGE MATERIALS. EVEN WITH STIFFENING RIBS, THESE PANELS ARE BUCKLING.
|
|
|
 |
BETWEEN THE 12 INCH AND 16 INCH WESTFORM PROLOK PANELS, MY COMPETITOR CHOSE THE WIDER PANELS THAT INSTALL FASTER.
|
|
|
 |
WORST CASE SCENARIO IS: A WIDE PANEL AND A LIGHTER GAUGE. BEST CHANCE FOR SUCCESS IS USING A NARROWER PANEL, PLUS A HEAVIER GAUGE, WHERE IS PLENTY OF COMPENSATION FOR EXPANSION AND CONTRACTION.

I OBSERVED THIS METAL ROOF BEING INSTALLED BY A COMPETITOR.
GAS STATION AND STORE AT 176 ST AND 8TH AVE SURREY.
|
|
|
 |
THESE ROOF PANELS ARE OIL CANNING, IN THE MIDST OF ON GOING CONSTRUCTION.
|
|
|
 |
THESE PANELS APPEAR TO BE WESTFORMS 16 INCH PROLOK PANELS.THE PROBLEM COULD BE THE USE OF A LIGHTER GAUGE MATERIALS, OR PERHAPS THE PANELS ARE INSTALLED TOO TIGHT. TERRIBLE PRESENTATION.
