Metal roofing has gained popularity for its durability, efficiency, and long-term value. Whether you're building a new home or upgrading an old roof, understanding how to install metal roofing properly is key to avoiding future leaks, energy loss, or structural issues.
Why Homeowners Are Switching to Metal Roofing
- Incredible Longevity: Most metal roofs last between 40 and 70 years.
- Energy Efficiency: Metal reflects solar radiant heat, reducing cooling costs by up to 25%.
- Low Maintenance: Doesn't crack, curl, or require constant patching.
- Fire and Weather Resistance: Non-combustible and stands up to extreme winds and hail.
- Curb Appeal and Value: Standing seam and other styles offer sleek finishes.
7 Steps To Install Metal Roofing
1. Measure the Roof and Order Materials
- Measure each slope including length, width, and pitch
- Add 10% for waste and cuts
- Choose your material and panel type
2. Remove the Old Roofing (Recommended)
- Inspect for damaged sheathing, rot, or moisture
- Repair soft spots before continuing
- Clean debris and old nails thoroughly
3. Install the Underlayment
- Use synthetic or felt underlayment rated for metal roofing
- Start at the eaves and roll upward, overlapping each layer by 4 inches
4. Install Furring Strips or Purlins (If Needed)
- Improves airflow and reduces thermal transfer
- Space evenly per manufacturer guidelines
5. Install Metal Panels
- Start at one corner, ensuring consistent overhang (1–2 inches)
- Fasten with rubber washer screws
- Overlap each panel per manufacturer specs
6. Flash Roof Features and Install Trim
- Use compatible metal flashing
- Apply butyl tape or sealant under flashing
- Install drip edge, ridge caps, and gable trim
7. Final Inspection and Cleanup
- Check for loose screws or gaps
- Remove metal shavings to prevent rust stains
- Use a magnetic roller for fasteners
