🧱 What Are Metal Shingles?
Metal shingles are a type of roofing material made from metal sheets but designed to look like traditional roofing tiles — such as slate, clay, or wood shakes.
They combine the strength and durability of metal with the classic appearance of other roof types.
🏭 Making / Manufacturing Process of Metal Shingles
Step-by-Step Process:
Raw Material Selection
High-quality steel are chosen.
Cleaning & Treatment
- Coils are cleaned to remove oil, dust, or impurities.
Galvanizing / Coating
- Metal is coated with zinc (galvanized) or aluminum-zinc alloy (Galvalume) for corrosion protection.
Base Painting / Primer
- A primer coat is applied for paint adhesion and surface protection.
Embossing / Press Forming
- Using molds, the sheets are pressed into tile-like patterns (like slate, clay, or shake textures).
Color Coating / Finishing
- High-quality PVDF or polyester paints are applied and baked for UV protection and shine.
Cutting & Packaging
- The sheets are cut into interlocking sizes, inspected for quality, and packed for delivery.
🎨 Design & Appearance
Metal shingles can be coated or painted in various textures and colors to mimic:
- Slate roofs
- Clay or terracotta tiles
- Wood shakes
- Stone-coated finishes
- Matte or glossy metallic looks
So visually, they look like traditional roofs, but they’re much stronger and lighter.
⚙️ Materials Used
Metal shingles can be made from different metals, such as:
- 🧲 Steel (Galvanized or Galvalume) – strong, affordable, long-lasting
- 🥈 Aluminum – lightweight and corrosion-resistant

🏗️ Installation Process of Metal Shingles
🔹 Step-by-Step:
- Roof Preparation
- Old roofing (if any) is cleaned or removed.
- A moisture barrier / underlayment (synthetic or felt sheet) is installed over the roof deck.
- Starter Strips
- Base edge metal strips are fixed to start the first shingle row.
- Panel Placement
- Metal shingles are placed in interlocking form, overlapping edges for waterproofing.
- Fastening
- Special screws or clips (corrosion-resistant) are used instead of nails.
- Panels are fixed to battens or directly on decking.
- Flashing & Ridge Caps
- Corners, valleys, chimneys, and joints are sealed with flashing to prevent leakage.
- Ridge caps cover the roof’s peak.
- Final Coating / Finish
- Optional color coat or protective coating applied after installation (for shine and protection).
✅ Installation Time: Usually 2–4 days for an average house (depending on roof size).
