Polycarbonate roofing is a lightweight, impact-resistant plastic sheeting used for pergolas, carports, patios, and outdoor living areas. It lets natural light through while blocking harmful UV rays, and it comes in profiled options (corrugated, Greca, 5-Rib) designed to match standard metal roofing profiles, as well as flat and twinwall formats. Supreme Plastic Roofing stocks polycarbonate sheeting in lengths up to 7.2m with warranties of up to 25 years.

Common uses
Polycarbonate roofing suits a wide range of outdoor structures. It's a popular choice for pergolas and patio covers, where it lets natural light through while keeping the space protected from rain and UV. Carports and covered walkways use it for the same reason, combined with its impact resistance. Skylight sections in an otherwise solid roof let polycarbonate bring light into a room without a full glass installation. It's also used in commercial settings for covered outdoor seating and awnings.

All profiled polycarbonate sheets are designed to sit directly alongside the equivalent metal roofing profile, so there's no mismatch where the two meet.
Choosing a brand and grade
| Brand | Warranty | UV coating | Best For |
|---|---|---|---|
| Calypso | 10 years, weather breakage | Standard | Cost-conscious projects, sheds, basic covers |
| Calypso Ultra | 25 years light transmission, 15 years weather breakage |
High-grade UV coating | Long-term installations, pergolas, patios where light clarity matters over time |

High-grade UV coating | Buyers wanting the original branded product; same base material and standard as Calypso Ultra |
Frequently Asked Questions
Cost depends on the brand and grade (Calypso versus Calypso Ultra versus Laserlite), the profile shape, sheet length, and colour. Calypso is the most cost-effective option with a 10-year weather breakage warranty. Calypso Ultra and Laserlite carry a higher-grade UV coating and a 25-year loss-of-light warranty, which sits at a higher price point. Get in touch with our team for a quote based on your project size and profile.
All three are profiled polycarbonate sheets designed to match the equivalent metal roofing profile, so they can be installed alongside existing metal roofing without a mismatch. The difference comes down to rib shape and spacing rather than performance. Corrugated has a rounded wave profile, Greca has a squared trapezoidal profile, and 5-Rib (Trimdek) has a narrower, more closely spaced rib pattern. Choice usually comes down to matching an existing roof or personal preference on appearance.
Calypso is our most cost-effective polycarbonate, backed by a 10-year weather breakage warranty. Calypso Ultra is a higher grade with a stronger UV coating, backed by a 25-year loss-of-light warranty and a 10-year weather breakage warranty.
Polycarbonate roofing typically lasts 10 to 30 years depending on the brand and grade purchased. All of our polycarbonate sheeting blocks 99.9% of harmful UV rays, which is what protects the sheet from degrading and going cloudy over time.
Yes. All polycarbonate roofing sheeting we stock blocks 99.9% of harmful UV rays while still allowing natural light through, so it protects both the space underneath and the sheet itself from sun damage.
Profiled polycarbonate sheets are available in lengths from 1.8m up to 7.2m. Colour options across our Calypso, Calypso Ultra, and Laserlite ranges include Clear, Grey, Bronze, and Opal, with Frost and Platinum also available in the Calypso Ultra Comfort Cool range.
Yes, polycarbonate roofing is a popular choice for DIY installation. The sheets are easy to cut with tin snips or a fine-toothed circular saw blade, and profiled sheets are designed to sit directly over existing purlins or rafters at a minimum 5° pitch. A full installation guide is available on our Installation page.
Polycarbonate roofing is often installed alongside metal roofing to bring natural light into a covered area, since it's manufactured to match standard corrugated, Greca, and 5-Rib metal profiles. Unlike metal, polycarbonate is translucent, so it's commonly used for pergolas, carports, and skylight sections where light transmission matters, while metal is used for the surrounding solid roof area.
Polycarbonate roofing suits pergolas, carports, patio covers, greenhouses, and other outdoor living areas where you want weather protection without losing natural light. It's used across residential, DIY, and commercial projects.
