Proper Handling and Storage of Metal Roofing Coils

Before installation, handle metal roofing coils with care to prevent scratches or dents. Store them in a dry, flat area to avoid moisture damage. For corrugated roofing sheets, stack them horizontally with protective padding between layers. Avoid dragging rolled metal roofing across rough surfaces, as this can compromise the galvanized coating. Proper storage ensures the material remains in optimal condition before installation.

Essential Tools and Techniques for Installing Corrugated Roofing Sheets

Installing corrugated roofing sheets requires the right tools, including metal-cutting shears, roofing screws with neoprene washers, and a drill. Begin by aligning the sheets correctly, ensuring proper overlap (typically 150mm for side laps and 200mm for end laps). Use corrosion-resistant fasteners to secure metal roofing panels, placing them at the crest of corrugations for a watertight seal. Avoid over-tightening screws, as this can distort the sheets.

Ensuring Weather Resistance with Rolled Metal Roofing 

Rolled metal roofing offers excellent weather resistance when installed correctly. Apply underlayment beneath the panels to prevent condensation and improve insulation. Seal joints and edges with high-quality flashing to enhance waterproofing. For sloped roofs, ensure proper drainage by maintaining a minimum pitch of 3:12. Regular inspections of metal roofing coils will help detect any loose fasteners or corrosion early.

FAQs About Metal Roofing Coils

What are the advantages of using metal roofing coils?

Metal roofing coils offer superior durability, weather resistance, and longevity compared to traditional roofing materials. Their lightweight nature reduces structural load, and the galvanized coating (Z30-Z40) ensures rust prevention.

How do I maintain corrugated roofing sheets? 

Inspect corrugated roofing sheets annually for loose fasteners or debris. Clean with mild soap and water to maintain appearance. Avoid abrasive cleaners that could damage the coating.

Can rolled metal roofing be painted? 

Yes, rolled metal roofing can be repainted using acrylic or polyurethane coatings. Ensure the surface is clean and primed for better adhesion. RAL Color 5007 can also be matched for touch-ups.

What is the lifespan of metal roofing?

Properly installed metal roofing coils can last 40-70 years, depending on maintenance and environmental conditions. The zinc coating significantly enhances longevity.

Do you offer customized sizes for metal roofing coils? 

Yes, we provide metal roofing coils in custom widths and lengths. OEM and ODM orders are accepted to meet specific project requirements.

Installing metal roofing coils, corrugated roofing sheets, or rolled metal roofing correctly ensures durability and performance.
