The Shapes of Roof Sheets
Corrugated roof sheets
These are the ‘wiggly’ polycarbonate sheets that are often found on shed roofs and give additional strength and impact resistance and stand up well to adverse weather. They also allow effective water runoff. Corrugated roof sheets should overlap by at least one corrugation.
Flat roof sheets
If you want a clean and linear finish, flat roof sheets are a clean and minimalistic choice and are also easy and quick to install
Box profile roof sheets
Box profile roof sheets are similar to corrugated sheet solutions in that there are peaks and troughs, but instead of being consist of sharper, linear edges giving them strength and the ability to withstand impact. They also have a favoured appearance.
Polycarbonate roofing can be
- Single sheets
- Twin wall i.e. double layered sheets
- Triple wall i.e 3 layers of sheets
- Multiwalled roof sheets – anywhere up to 7 layers
The more layers there are, the greater the insulation and strength, of the roof allowing you to cover larger areas.

How to cut roofing sheets
It depends on what type of roofing sheet you are cutting.
Polycarbonate roofing sheets can be c cut with circular saw or jigsaw because the properties of polycarbonate means it won’t splinter around the cut.
Single metal roof sheets can be cut with electric shears or nibblers.
