TNR Roofing
Durable Roofing Solutions
With over 20 years of experience, TNR Roofing manufactures and supplies GI (galvanized iron) and Zinc Aluminium (Zn/Al) roofing sheets built to withstand Sri Lanka's toughest conditions — heavy monsoon downpours, coastal salt air, and intense tropical heat. Every sheet passes through our in-house quality controls before it reaches a job site.
Our GI Roofing Sheets are a practical, cost-effective choice for temporary structures such as site sheds, storage shelters, and short-term coverings, available in standard 6, 8, 10, and 12 foot lengths. For permanent structures and coastal properties, our Zinc Aluminium Roofing Sheets combine an AZ150 corrosion-resistant coating with heat-reflective properties, available in multiple profiles, thicknesses (0.30 mm – 0.47 mm), and finishes — including Reddish Brown, Autumn Red, Caulfield Green, Lazrite Blue, Amethyst Blue, and Zincalume.
No roof is complete without the right finishing touches. Our full range ofRoofing Accessories — gutters, downpipes, ridge capping, wall and barge flashing, and gutter brackets — manages rainwater and seals joints to keep interiors dry through even the heaviest rains.
