15 Steps to Follow on How to Install Polycarbonate Roofing 

Step One:  Marking Out

Polycarbonate roof sheets are usually slightly larger than the hole that they have to be fitted into. Measure the pane’s height with a tape measure or ruler, then add 10mm extra to allow for clearance at the top and bottom of the sheet. Remove all dirt and debris from the installation area with a stiff brush or hand-held vacuum cleaner. If the surface is uneven, hold your tape measure on edge and use it as a straight edge for marking out. Use a spirit level to ensure that the polycarbonate is installed at the correct pitch or angle.

Step Two: Cutting Out

Place the marked sheet over the opening and use either tin snips or shears to cut out your installation hole. Take care when cutting, as this is difficult if you are working in an awkward location. If using a small hacksaw or fret saw, try drilling a hole through the polycarbonate to help the blade cut all the way through. Be sure to wear goggles, gloves and use a dust mask during this process.

Step Three: Preparing and Attaching Flashing

Once you have the opening cut out, use a file to remove any rough edges. Next, clean the area around the installation hole with soap and water and then dry it. Next, apply a layer of primer to the bottom lip of the flashing, making sure not to get any on paint or other surface areas.

Attach the flashing to the wall with nails or screws. The goal is to create a seal between the flashing and the side of the building so water can’t seep in behind your new window. Next, apply caulk over all seams along with roofing and siding, both under and on top of flashing. Make sure all seams are seated correctly and will be watertight.

Step Four: Installing the Polycarbonate Sheets

Lay your first polycarbonate sheet over the opening and attach it to the flashing using screws or pop rivets. You can use framing nails, but these will rust if they get wet, damaging the roofing and polycarbonate materials you are using.

Attach the other side of the sheet to the building with more screws or rivets. Be sure the sheets are flush with one another, and you have a watertight seal all around the installation hole.

Step Five: Venting

Venting is an essential step when installing polycarbonate. These sheets will warp and buckle if the humidity level inside your home exceeds 75%. Because of this, it is best to have an intake vent on one side and an outtake vent on the other side.

The intake should face into your house, while the outtake should face away from your home. Use a drill with a hole saw bit to cut the holes. Drill a starter hole first, and then make the actual vent holes slightly smaller than the intake and outtake tubes you are going for.

Attach both vents to either side of your polycarbonate sheets, caulking around all seams as you go.

Step Six: Finishing the Installation

Make sure all your vent tubes are facing away from home and attached securely to the polycarbonate sheets. Attach them with screws or rivets, but be careful not to hit any exposed nails or sharp edges on installation with your drill when attaching them.

When you have successfully installed all of your venting tubes, you can attach the final piece of polycarbonate over your opening. Again, you might want to add trim or a covering for aesthetic purposes. You can also cut away part of the sheet in order to create an operable window that opens and closes if desired. In addition, you will need to decide whether you’re going to have a traditional roof or a sloped one.

Step Seven:  Finishing Touches

If you want to paint your vent tubes or outside covering, choose a product that will dry quickly and be unaffected by humidity. Apply several coats of the paint around your tubes, as well as on any screws or rivets, for a final finishing touch. You can also attach a gutter if desired unless this is going to be an indoor window.
