Check the temperature of the storage area when the PVC panels are located to ensure that it is above 40 degrees Fahrenheit. If the area is below this temperature, move the PVC roofing panels into a heated area and let them sit overnight to acclimate before cutting.
Place a PVC roof panel on the roof in the area where you want to install it. Draw a line on the panel using a pencil to indicate where it requires cutting.
Place the panel on top of two saw horses, ensuring that the pencil line hangs freely. Clamp the panels to the saw horses to ensure that they don’t move while cutting.
Insert a plywood cutting blade into a standard circular saw with the teeth facing backward. The teeth have small hooked portions at the bottom.
Don safety glasses and plug the cord of the circular saw into an outlet. Squeeze the saw trigger and slowly move the spinning blade toward the pencil line on the PVC panel until it begins to cut through it. Continue cutting at a slow pace until reaching the opposite side of the cut line.
