Types of roofing sheets
There are many types of roofing sheets available in the market, each with its own advantages and disadvantages. The most common types of roofing sheets are made from asphalt, metal, tile, and plastic. Asphalt roofing sheets are the most inexpensive option and are easy to install. However, they are not as durable as other types of roofing sheets and can be damaged by severe weather conditions.
Metal roofing sheets are more expensive than asphalt roofing sheets but are much more durable. They can withstand severe weather conditions and will not be damaged by hail or high winds. Tile roofing sheets are the most expensive option but are also the most durable. They can last for decades with proper maintenance and can withstand even the most severe weather conditions. Plastic roofing sheets are a relatively new option and are becoming increasingly popular due to their low cost and easy installation.

FAQ
Which is best sheet for roofing?
PVC Plastisol coated corrugated sheets are very durable. They comprise steel sheets treated with primer paint and PVC rolled on their surface. These roofing sheets don’t scratch or fade easily and typically can last for around 25-30 years.
Frequently Asked Questions (FAQ)
1) What materials can a Roofing Sheets Roll Forming Machine handle in 2025?
- Typical coils include galvanized steel (ASTM A653/EN 10346), galvalume/aluzinc (AZ), pre-painted steel (EN 10169), aluminum (3000/5000 series), and occasionally copper. Thickness range is commonly 0.3–1.2 mm depending on profile and machine tonnage.
2) What tolerances are achievable for corrugated and trapezoidal roofing sheets?
- Length: ±1.0 mm with encoder-based control and flying cutoff; profile height: ±0.5 mm; cover width: ±1.0 mm at speeds up to 60–90 m/min, assuming inline width gauges and temperature-stable setup.
3) How does roll forming reduce roofing project costs?
- It minimizes scrap (<2%), supports long continuous runs (fewer overlaps and leaks), and enables on-demand lengths onsite with portable lines, cutting transport and installation time.
4) What is the difference between single-layer, double-layer, and standing seam machines?
- Single-layer: one profile per line. Double-layer: two profiles share one base, switch via hydraulic/servo selector for fast changeover. Standing seam lines include specialized seaming geometry and sometimes curving/arch modules.
5) How can I improve corrosion performance of formed roofing sheets?
- Use AZ-coated or pre-painted coils per EN 10169, specify proper coating weights (e.g., Z275/AZ150), apply protective films to prevent scratch damage, and ensure correct bend radii and roll polish to avoid micro-cracking of coatings.
2025 Industry Trends
- Faster changeovers: Auto-stand positioning and recipe-driven tooling reduce profile changeover to 8–12 minutes on double-layer machines.
- Inline quality control: Laser cover-width gauges and camera-based rib alignment checks raise first-pass yield to 98–99%.
- Energy efficiency: IE4/IE5 motors and regenerative drives lower energy intensity to 55–75 kWh/ton on best-in-class roofing lines.
- Digital traceability: OPC UA/MQTT connectivity enables coil-to-bundle traceability, helping meet project EPD and warranty requirements.
- Sustainability demand: Growth in pre-painted cool roofs with high SRI values and low-VOC lubricants for cleaner operations.
