PVC Roofing Sheets for the U.S.: Specs, Uses, Importing from Vietnam

Mr Quyen - Santiago · Editor: Santiago Plastic Roofing · Updated 22/10/2026 · 4 min read

ASA/PVC roofing sheets from Santiago (Vietnam) are 4-layer plastic sheets with an ASA weathering top and three PVC layers, 100% virgin resin. They do not rust, keep the space under the roof 6–8 °C cooler and about 80% quieter in rain than galvanised steel (Santiago measurements), and weigh 5.2–6.2 kg/m². Santiago began shipping to the U.S. in 2025; minimum order is one 40 ft container.

1. Why are PVC roofing sheets getting attention in the U.S.?

Metal roofing is common on U.S. barns, sheds and warehouses, but it rusts at cut edges and screw holes, gets hot in summer and is loud in rain. Livestock buildings and coastal properties make the corrosion worse. ASA/PVC sheets solve those three problems while staying light and quick to install, which is why distributors and contractors are asking for them.

2. Who makes these sheets?

Santiago is a Vietnamese manufacturer and a leading exporter of ASA/PVC roofing sheets, with shipments to India (2023), Thailand (2024) and the United States (2025). It makes four profiles: Spanish (Roman) tile and 5, 6 and 11-wave square profiles. We are looking for U.S. distributors, contractors and importers to work with.

3. How is the 4-layer ASA/PVC sheet built?

ASA top layer (acrylonitrile styrene acrylate): blocks UV and keeps the colour; rated for 30 years of colour retention.
Three PVC layers: give stiffness and impact strength and slow heat transfer (PVC conducts under 0.2 W/m·K, steel about 50 W/m·K).
All layers: 100% virgin resin, no recycled filler.

5. Which U.S. projects suit PVC roofing sheets?

Homes: Spanish tile profile for a tile look at a fraction of clay tile weight.
Barns, poultry and hog houses: ammonia from manure corrodes steel; PVC does not.
Warehouses and workshops: 6 or 11-wave profiles for long runs and low slopes.
Coastal buildings: no rust from salt air.
Carports, sheds and patio covers: light, quick to install, quiet in rain.
