1. What Is Polycarbonate Roofing?
Polycarbonate roofing (shortened as poly roofing) is a type of roof sheeted with polycarbonate sheets – a high-tech engineering plastic material having capacities for good light transmission, load resistance, heat insulation, and anti-UV protection. This is a popular choice for categories such as: rooftop coverings, skylights, parking lots, porches, factory day-lighting roofs, etc.
Depending on needs, you can choose:
-
Solid poly sheets (strong light transmission, high durability),
-
Hollow poly sheets (lightweight, heat insulating, cost-saving),
-
Corrugated poly sheets (replacing corrugated day-lighting sheets).
2. Advantages When Constructing Polycarbonate Roofing
✅ Natural light transmission: Helps save daytime lighting electrical power.
✅ Good load resistance, weather durability: Does not shatter brittly like glass, with lifespans from 10–15 years.
✅ Anti-UV, heat insulating: Protects health and inside interiors.
✅ High aesthetics: Many colors, easy to shape, fitting both modern and traditional projects.
✅ Easy construction and maintenance: Fast installation, lightweight material, saving labor.

3. Instructions for technically correct Polycarbonate Roofing Construction
Step 1: Prepare materials and tools
-
Polycarbonate sheets of the correct type, thickness from 5–10 mm.
-
Box steel frames, aluminum profiles, or stainless steel.
-
Stainless steel bolts, rubber washers, H-trim, U-trim, neutral silicon,…
-
Drilling machines, cutting machines, labor safety tools.
Step 2: Construct the roof framework
-
Calculate frameworks having a minimum slope of 5–10% for good water drainage.
-
Distance between support bars: 600–1000 mm depending on sheet type.
-
Ensure the framework is solid, not sagging, and not warped.
Step 3: Cut poly sheets and place onto framework
-
Cut correct dimensions, leave thermal expansion gaps from 3–5mm between sheets.
-
Place correct side of anti-UV layer facing out (usually has writing or stamps).
-
Use H-trim to connect sheets, U-trim to cap sheet ends (for hollow sheets).
Step 4: Fix sheets using screws
-
Drill holes wider than screws by 1–2mm so sheets have expansion room.
-
Use screws with waterproof rubber washers, tighten moderately.
-
Do not drill near sheet edges to avoid cracking.
Step 5: Waterproofing finishing
-
Pump neutral silicon into connection gaps and screw heads.
-
Check carefully interface positions between poly sheets and walls, water gutters, etc.
4. Important Notes When Constructing Poly Roofing
-
Do not remove the protective film layer of poly sheets before completing installation.
-
Do not use acidic silicon, because it can cause staining or sheet cracking.
-
Do not step directly onto poly sheets, planks must be placed if working on the roof.
-
Clean the roof periodically, do not use strong chemicals (like petrol, oil, acetone).
