Ejoy Corrugated Polycarbonate Roof Panel vs Corrapol Stormproof Corrugated Roof Sheet

Buy the Corrapol Stormproof if you want a clear sheet built to last: its UV-protected polycarbonate is rated for about 20 years and resists the yellowing and brittleness that ruin cheap corrugated sheets. The Ejoy panel is a longer, narrower sheet (72 in. by 21 in.) that is 20 times stronger than 5 oz. fiberglass and handles -40° to 270°F, but it carries no UV or lifespan claim. Owners of the Corrapol rate it 4.7 out of 5 and praise easy cutting, drilling and no yellowing; the main complaint is that diagonal cuts are hard to make neatly.

• Choose the Ejoy panel if you need a long 6 ft sheet for under-deck drip-stop or a narrow patio run and want fiberglass-grade strength without a UV rating.
• Choose the Corrapol Stormproof if you want a UV-protected sheet with a stated 20-year lifespan for a carport, canopy or walkway.
