Steel craftsmanship & pedigree
JJ Roofing – Steel Builder (Roofs India) is a roofing and structural-steel contractor based in Tamil Nadu. We design, fabricate and install metal roofing sheets, pre-engineered industrial sheds, residential terrace canopies, polycarbonate skylights and roof leak repairs for homes, factories and warehouses across Chennai, Coimbatore, Madurai, Tirupur and the rest of South India.
We source only from certified rolling mills: genuine Tata BlueScope Steel, JSW Colouron+ and Jindal Aluminium. Our structural welders and site engineers calculate live loads, wind deflection and dead weight on every job, so each roof is built for severe monsoons, high-heat oxidation and coastal winds.
“A roof is not merely a covering; it is the frontline shield of your home, inventory and industrial enterprise.”

+91 90032 91290 (Direct Line)A complete residential terrace roof, including fabrication and installation, typically costs about ₹180 to ₹320 per sq.ft.
The price depends on three things: the steel frame (tubular pipes or heavy I-beams), the sheet brand and gauge, and the working height. Large industrial sheds are priced by structural steel weight per metric tonne plus cladding area. Our site visit and itemised estimate are free, so you see exact numbers before committing.
Use 0.45 mm to 0.50 mm Galvalume sheets for homes and terrace canopies, and 0.55 mm to 0.60 mm for factories, warehouses and coastal areas.
Both are AZ150 GSM Galvalume (Tata BlueScope Colorbond or JSW Colouron+). The thicker gauge resists strong winds, chemical fumes and heavy foot traffic during maintenance.
Light-coloured, heat-reflective colour-coated Galvalume sheets with an insulation layer underneath keep a building noticeably cooler than bare metal.
For hot industrial interiors we add turbo ventilators and, where daylight is useful, polycarbonate skylights that block harmful UV. We recommend the right combination after seeing your roof and usage during the site visit.
A standard residential terrace canopy of 1,000 to 2,500 sq.ft takes 3 to 7 working days, and an industrial shed of 10,000 to 50,000 sq.ft takes about 25 to 45 days.
Steel is fabricated in our workshop first and then assembled on site, which keeps disruption to your plant or home to a minimum.
Our written, stamped 10-year warranty covers water seepage at sheet overlaps, fastener drill points and gutter connections, plus weld-point cracking under normal weather.
If an issue appears, our team inspects and fixes it within 48 hours at no cost. The warranty applies where both steel fabrication and sheet installation were carried out by our certified teams using approved fasteners with EPDM washers.
For critical factories and logistics hubs, an inspector visits within 24 hours.
We carry temporary tarpaulin clamps and rapid-curing elastomeric sealants to stop the leak immediately, then carry out the permanent repair or re-sheeting, often without stopping your operations.
No. The site visit, laser measurement and itemised estimate are completely free with zero obligation.
You receive a clear proposal with material specifications and a bill of quantities before you make any commitment.
Yes. We re-sheet ageing asbestos and GI roofs with insulated, colour-coated metal sheets.
We also replace valley gutters and fix loose fasteners during the same job, and we plan the work in phases so factories can keep running.
We serve Chennai, Coimbatore, Madurai, Tirupur, Salem, Trichy, Hosur, Erode, Vellore and the rest of Tamil Nadu.
Select industrial contracts also taken up in Bengaluru, the Andhra Pradesh border belt and Kerala.
