How to Fit Polycarbonate Roofing Sheets

Laying the sheets and glazing bars correctly is a vital part of the installation process, making sure that your sheets fit the structure correctly; with no gaps or unevenness. It can be tempting to skip this step since you should have already measured the area and sheets, but you don’t want to be caught out halfway through fixing your sheets!

You can also take time during this part of the process to ensure that your sheets are as sturdy as they need to be. Polycarbonate sheets are favored for their high impact resistance, though this is only truly effective once the panels fit to the roof correctly. This will prove the same for your roof’s effectiveness at resisting water during storms and showers.

Now it’s time to start fixing your sheets properly. Before we get to the sheets, however, it’s best to start with the glazing bars.

  1. Glazing bars should be placed on the edges of your roof, with holes drilled around 500mm apart. You can then use these holes to insert your fixings and effectively secure your bars ready for the sheets.
  2. Most roofs will require eaves fillers, and yours should be added at this point in the process. You can then begin to add your sheets, starting by attaching one to the glazing bar on one end of your roof. You can then line up your sheets on the roof ready for fixing.
  3. There should be a glazing bar attached between each sheet, which will help to properly seal any gaps between them. Once the sheets have been aligned on your roof and attached to the bars, you can finish off by adding the screw caps and screws, creating a secure, reliable fix.
  4. At this point, you can remove any protective film on your sheets, and then start to drill holes into the sheets and add screws and/or fixing buttons which will further strengthen your polycarbonate roof.
  5. There are various other things you can do to make your roof more effective, for example adding flashing if your roof attaches to another wall.

Once these steps are complete; it’s time to start making the final adjustments to your roof. Clearing the sheets of any dust caused by the drilling process is recommended, as is ensuring that any screw caps and/or buttons you have used have been properly applied are uniform across the roof.

Storing Unused Polycarbonate

If you have any polycarbonate roofing left and would like to store it for later use, it is best kept in an interior location to minimize wear. This also goes for any equipment and accessories you may have used in the building process.
