Meta description: Learn what plastic roofing sheets at Wickes are used for, how to compare polycarbonate and PVC options, and what to check before buying or installing them.
Searching for plastic roofing sheets at Wickes usually means looking for a lightweight, weather-resistant covering for a shed, greenhouse, carport, canopy, or similar structure. Wickes is a UK retailer, so its range, prices, product names, and delivery options are intended for the UK market and can change. For shoppers in the United States, the same material choices and installation principles apply, but local product availability, building codes, and weather requirements may differ.
What “Plastic Roofing Sheets” Means at Wickes
Plastic roofing sheets are panels made from polymers rather than metal, asphalt, or glass. They are commonly used on small buildings and covered outdoor areas where low weight, daylight, or straightforward installation matters. At Wickes, shoppers may find plastic roofing products or related roofing accessories, but the exact selection depends on current stock and location. A product listed online may not be available at every branch.
The phrase can refer to several different products, including corrugated PVC sheets, solid or multiwall polycarbonate panels, and plastic rooflights designed to fit a particular roofing profile. These materials are not interchangeable. They differ in strength, light transmission, insulation, flexibility, installation requirements, and suitability for different structures.
Before comparing products, check the product’s material, profile, thickness, dimensions, color or transparency, and stated application. A sheet intended for a greenhouse roof may not be the right choice for a long-span carport or a roof exposed to heavy snow. The manufacturer’s installation instructions and product data sheet should guide the final decision.
Common Types of Plastic Roofing Sheets
Corrugated PVC Sheets
Corrugated PVC sheets have a repeating wave profile that helps direct rainwater toward the eaves and adds stiffness compared with a flat sheet of similar thickness. They are often used for sheds, lean-tos, and simple covered areas. PVC is generally lightweight and easy to handle, though product performance varies by thickness, formulation, and support spacing.
Corrugated sheets are available in clear, translucent, or opaque finishes. Translucent versions admit daylight, while opaque colors provide more shade and privacy. Buyers should check that the chosen sheet is compatible with the roof’s pitch, the support structure, and any adjoining roof panels or flashing.
Polycarbonate Sheets
Polycarbonate is a tough, lightweight plastic available in several formats. Solid polycarbonate panels resemble clear glazing, while multiwall panels have internal channels that can improve thermal performance and rigidity. Corrugated polycarbonate is also sold for profiled roofing applications. Polycarbonate is often selected when daylight and impact resistance are important, but the product’s specifications—not the material name alone—determine its actual performance.
Many polycarbonate roofing systems require attention to panel orientation, thermal expansion, edge sealing, and compatible fasteners. Multiwall panels typically have a designated top and bottom edge, and their flutes usually need to run in the direction of drainage. Following the manufacturer’s instructions helps reduce water ingress, condensation problems, and premature damage.
Plastic Rooflights
A rooflight is a translucent panel or component designed to bring daylight through a roof. Some are intended to match a specific corrugated or trapezoidal profile. A compatible rooflight can be more reliable than trying to combine unrelated sheets, because the profile and fixing details are designed to work together. Check the stated roof profile, dimensions, and recommended installation method before purchasing.
How to Choose the Right Sheet
The best plastic roofing sheet depends on the building, local climate, and intended use. A small garden shed has different demands from a frequently used patio cover. The following checks can narrow the options:
- Application: Confirm whether the sheet is intended for a shed, greenhouse, canopy, rooflight, or another use.
- Material and profile: Match the sheet to the roof design and supporting structure. Corrugated and multiwall panels use different fixing details.
- Dimensions: Measure roof length and width, including required overlaps and overhangs. Compare usable coverage, not just the panel’s overall dimensions.
- Light and privacy: Clear panels admit more light; tinted or opaque finishes reduce glare and direct sunlight.
- Weather exposure: Consider wind, rain, snow, hail, and strong sun. Check the manufacturer’s limits for span and support spacing.
- Accessories: Confirm whether matching screws, washers, closures, flashing, and edge trims are required or sold separately.
- Warranty and care: Review warranty conditions, cleaning guidance, and any restrictions on installation or chemical cleaners.
For products sold in the UK, the manufacturer’s technical information and applicable UK building requirements are relevant. In the United States, buyers should also check local permitting rules and adopted building codes. Requirements can vary by state, county, city, building type, and site conditions.
Measuring and Planning a Roof
Start by measuring the roof’s slope length and width, not just the footprint of the structure. The slope length runs from the high edge to the eaves. Include any planned overhang, and account for the overlap specified by the sheet manufacturer. Side laps and end laps affect how many sheets are needed and how much of each sheet provides actual coverage.
Next, identify the roof framing and the spacing between supports. Plastic panels must be supported at intervals suited to their thickness, profile, and expected loads. A sheet that spans too far may flex, leak, or fail under wind or snow. Do not assume that a panel can be cut to any size or installed over widely spaced battens; use the product’s span tables where available.
Plan drainage before installation. The roof must have a suitable fall for water to run off, and the sheet profile should direct water toward the eaves. Roof pitch requirements vary by product. Where a roof joins a wall or another roof, plan for flashing and compatible weatherproofing details rather than relying on sealant alone.
Installation Considerations
Plastic roofing can be manageable for a competent DIY installer, but safe access and correct fixing are essential. Work from a stable platform, use appropriate fall protection, and follow local safety guidance. Never walk directly on unsupported plastic roofing sheets. Panels can crack or give way without warning. If the roof is high, steep, or difficult to reach, a qualified roofing professional may be the safer choice.
Cutting and drilling instructions differ by material and product. Some panels need clearance around fasteners so they can expand and contract as temperatures change. Over-tightening screws can distort a sheet or damage its surface. Use the specified screws, washers, and fixing locations, and avoid incompatible sealants or cleaners that could harm the plastic.
Keep protective films in place during installation if the manufacturer recommends it, then remove them at the stated stage. For multiwall polycarbonate, use the approved tapes, end closures, and channel details. Incorrectly sealed channels can collect dust or moisture. Corrugated panels may require profile-matched closures to help prevent wind-driven rain, debris, or insects entering at the roof edges.
Advantages and Limitations
| Feature | Potential advantage | What to check |
|---|---|---|
| Low weight | Can be easier to transport and handle than glass or some heavy roofing materials. | Light panels still need a sound frame and properly spaced supports. |
| Daylight | Clear or translucent sheets can brighten sheds and covered spaces. | Sunlight may cause glare or heat buildup; consider tint, ventilation, or shading. |
| Weather resistance | Products are designed for outdoor use when installed as directed. | Wind, snow, UV exposure, and temperature limits differ by product. |
| Installation | Some small-roof applications can suit DIY work. | Correct laps, fixings, fall, and safe access are critical to performance. |
| Appearance and lifespan | Several colors and profiles are available. | Plastic can scratch, discolor, or become brittle over time depending on product and exposure. |
Plastic roofing is not automatically the cheapest option over the life of a roof. A low purchase price may be offset by a short service life, poor fit, or the need to replace damaged panels. Compare the total cost of sheets, compatible accessories, delivery, installation, and expected maintenance rather than judging by price per sheet alone.
Finding Plastic Roofing Sheets at Wickes
To check Wickes’ current range, search its website for terms such as “plastic roofing sheets,” “corrugated roofing,” “polycarbonate roofing,” or “rooflights.” Product descriptions and filters can help identify dimensions, color, material, and intended use. Because stock changes, verify availability for the chosen delivery postcode or local store before making plans.
Compare the product page with the manufacturer’s technical documents. Look for the coverage per sheet, recommended pitch, support spacing, overlap, fixing pattern, and accessory requirements. If these details are missing or unclear, contact the retailer or manufacturer before buying. A low-cost panel that does not match the roof profile can create more work than it saves.
For U.S. shoppers, Wickes is not a domestic nationwide building-supply chain. Similar materials may be sold through local lumberyards, roofing suppliers, and home-improvement retailers. Search by the specific material and profile—such as corrugated PVC, corrugated polycarbonate, or multiwall polycarbonate—then compare local specifications and code requirements. UK product dimensions and installation instructions should not be assumed to match U.S. products.
Care, Cleaning, and Repairs
Inspect plastic roofing periodically, especially after severe weather. Look for loose fixings, cracked or lifted panels, blocked gutters, damaged flashing, and signs of water entering the structure. Replace damaged components with products compatible with the original system. Mixing panel profiles or fastening systems can compromise the roof’s fit and weather resistance.
Use the cleaning method recommended by the manufacturer. A soft cloth or sponge and mild soapy water are often appropriate, but abrasive pads, harsh solvents, and unapproved pressure washing can scratch or damage some plastics. Clear leaves and debris from roof valleys and gutters without placing weight on unsupported panels. If a panel is cracked or loose at height, avoid attempting a repair from an unsafe ladder or roof surface.
Questions to Ask Before Buying
- Is the sheet designed for the exact roof profile and intended use?
- What is the recommended roof pitch and maximum support spacing?
- How much usable coverage does each sheet provide after laps?
- Which screws, washers, closures, tapes, and flashings are required?
- Does the product carry a stated warranty, and what installation conditions apply?
- Will local rules require a permit or particular structural design?
Checking these points before purchase makes it easier to compare plastic roofing sheets at Wickes with alternatives from other suppliers. The right choice is the panel system that fits the roof, meets local requirements, handles expected weather, and can be installed with compatible components.
