Drilling Polycarbonate Roofing Sheets – Step-By-Step Process


Drilling Polycarbonate Roofing Sheets – Step-By-Step Process

In this step-by-step guide, I will show you how to drill polycarbonate roofing sheets without causing any damage.

They steps are simple and straight forward. As long as you have the right tools, this guide will help you drill polycarbonate sheets.

Step 1: Assemble Tools & Equipment For Polycarbonate Sheet Drilling

The right tools and equipment makes drilling polycarbonate easier.  You cannot drill polycarbonate if you don’t have the right or partial tools.

The essential tools/equipment you need for drilling polycarbonate roofing sheets include:

  • Flat Surface
  • Clamps/ Tape
  • Pointer/ Marker
  • Appropriate Drill + Drill Bits
  • Power Connection

Step 2: Placing Polycarbonate Sheet On Flat Surface

The second step is the polycarbonate sheet placement. Again, remember to place the sheet on a uniform or even surface rather than a non-uniform or uneven surface.

Placing it on an uneven surface will adversely affect the drilling process and result in the wrong placement of holes. A flat table or marble slab will serve the purpose in this regard.

Step 3: Clamping Polycarbonate Roofing Sheet

The clamps keep the sheet in place by holding it firmly. This enables you to drill holes in the exact location without disturbing the hole cross-section. You can place clamps on all the corners of the sheet.

Step 4: Marking the Holes on Polycarbonate Roofing Sheet

In this step, you need to pick up a pointer or marker and mark the points you want to drill the holes. Next, calculate the number of holes you want to drill.

An optimum number of holes maintains specific strength to the roofing. While exceeding a certain limit will affect stability. A mark or tape will help you drill the hole in the appropriate location.

Step 5: Selecting Drilling Machine Type

Different types of drills exist in the market, suitable for specific applications. For example, some are suitable for wood, some for metal, some for masonry or brick, and some for plastic.

The strength of polycarbonate or molecular structure is less in strength than metal or masonry. So, choosing the right drill does matter. For example, it would help to use a 13mm rotary hammer drill.

Step 6: Selection Suitable Drill Bit

The next thing you need to take care of is the drill bit selection. It also depends on the hole size you want to drill.

The wrong bit can lead to chip formation while drilling on the hole polycarbonate roofing sheet. You can use a standard iron drill bit or dowel bit/ spur point drill bit featuring an angle of 600 or 1200 per your need.

Step 7: Positioning of Drill Just Above Polycarbonate Roofing Sheet

Positioning the drill is another critical factor. Wrong positioning can lead to tilted hole formation.

So, it would be best if you placed the drill at an angle of 900 to the surface of the polycarbonate sheet. While drilling, ensure still handling.

Step 8: Now Drill Polycarbonate Roofing Sheet

Now start the drill by pressing the run button slowly. Begin with the medium speed and then slightly increase the speed.

When drilling a polycarbonate sheet, run it between 1500 to 2500 RPM. This will result in a smooth hole formation.

Step 9: Keep Consistent Drilling Pace

The pace determines the hole’s distance from the edge of the polycarbonate sheet.

Make sure to keep the pace twice the thickness of the polycarbonate sheet. Doing this will prevent cracking on the edges.

Step 10: Assess Hole Quality In Polycarbonate Roofing Sheet

After drilling, assess the quality of the hole. If the hole is smooth and uniform, then it is good. If not, check the process steps to see if you have correctly implemented everything.


We have discussed all the essential steps you are looking for in drilling polycarbonate roofing sheets. If you follow the steps discussed, you will end up with uniform drilling.
