How do I Install Roof Panels on my Structure?

08/30/2016 · HT030

Installing the roof panels is very similar to installing the siding in that you want to make sure the panels are straight and that the screws line up. You can’t use your level to check roof panel alignment, but you can use a measuring tape from the leading edge of the panel being installed to the next roof truss. Checking at both the top and bottom of the panel should help to ensure they stay straight. The string method used to align the screws on the siding panels also works on the roof.

You should not have to do any roof panel trimming as VersaTube sends the metal in the correct lengths for your building. When you’re ready to start, follow these steps:

• • The roof panels are designed to overhang the edge of the eave trim you installed previously by two inches. Install a screw partially in the eave end of the rear most roof truss on one side so that the head is two inches past the eave trim. Do the same on the front of the building on the same side and then attach a string tightly between the two screws – this string will be used to align the bottoms of the roof panels.

• • Measure the length of a roof panel and then pull the same measurement up from your string to the peak of the roof on the rear most roof truss. Install a screw in the outside face of the roof truss and tie another string to the screw. Repeat at the front of the building and pull the string tight on this screw. This will line up the tops of the roof panels on that side of the roof.

• • Repeat the above steps on the other side of the roof.

• • Installing the roof panels works best if someone is on an extension ladder near the peak of the roof, another helper is on a stepladder near the center of the roof and a third person is on the ground to hand up panels. Once the panel is on the roof, the third person should situate a stepladder at the eave so they can line up the bottom of the panel with the lower string. Start at the rear of the garage and work toward the front when installing panels.

• • The first panel should line up with the outer edge of the last roof truss and both the top and bottom strings. Once the panel is situated properly, it can be secured with color coordinated screws with rubber washers. There should be a screw on each side of the primary ribs wherever they cross the roof purlins. Don’t screw the last rib until the next roof panel is put in place and overlapped.

• • Don’t be alarmed if the roof panels don’t reach all the way to the peak of the building – that’s the way they’re designed and a trim piece will be used to cover the gap.

• • Continue installing panels until you reach the front of the building taking care that each sheet is lined up carefully with the top and bottom strings. It’s a good idea to measure the leading edge of at least every other panel to the next framing member to ensure your installation is straight.

• • When one side is complete, start at the rear of the building and install the panels on the other side. Check to ensure all screws are in place as it’s very easy to miss a rib.

Once all of the panels have been installed, remove your strings as you’re ready to put the finishing touches on your garage.
