Wondering how to install metal roofing on your home? Whether you’re replacing old shingles or planning a new build, understanding the process is key to making the right decisions for durability, cost, and appearance.
While professional installation is always recommended—especially for complex rooflines—this step-by-step guide will walk you through what’s involved, what tools you’ll need, and where things can go wrong.
Why Choose Metal Roofing?
Metal roofing has become increasingly popular for both residential and commercial properties. It’s known for:
- Exceptional longevity (often 40–70 years)
- Weather resistance, especially in snowy or windy climates like Michigan
- Energy efficiency, reflecting heat and reducing cooling costs
- Sustainability, as many metal panels are made from recycled materials
Understanding how to install metal roofing helps you appreciate the craftsmanship involved—and determine if it’s something you want to take on yourself.
How to Install Metal Roofing: Step-by-Step
1. Tear Off Old Roofing (If Needed)
Remove existing shingles unless installing over a single layer. Check local codes—some allow direct install if conditions are right.
2. Inspect the Roof Deck
Look for rot, mold, or structural damage. Replace damaged decking before continuing.
3. Install Underlayment
Roll out synthetic underlayment across the decking, overlapping each row by at least 6 inches. Secure with roofing nails or staples. This acts as a moisture barrier beneath the panels.
4. Add Drip Edge and Closure Strips
Install a metal drip edge along all eaves and rakes. This protects the roof’s edge and improves water runoff. Use closure strips to block air and insect infiltration beneath panel ridges.
5. Lay Down the Metal Panels
Start at one bottom corner of the roof, aligning your first panel squarely with the eaves. Overlap panels according to manufacturer specs and secure with metal roofing screws in the flat part of the panel (not the ridge). Use a chalk line to maintain straight rows.
6. Install Flashing
Flash around chimneys, skylights, and valleys using pre-bent flashing pieces. This prevents water intrusion at vulnerable points.
7. Secure the Ridge Cap
After all panels are installed, add a vented or solid ridge cap to finish the peak of the roof. Apply butyl tape or sealant under the ridge before screwing into place.
Common Mistakes to Avoid
Even if you know how to install metal roofing in theory, it’s easy to make costly errors. Avoid these:
- Incorrect screw placement or overdriving Can lead to leaks or metal distortion.
- Improper panel alignment Once the first panel is crooked, the whole row can be off.
- Insufficient underlayment or flashing Results in moisture problems, especially in snow-prone areas like Michigan.
- Skipping closure strips Leads to pest problems and poor insulation.
Cost Considerations
While the upfront cost of metal roofing is higher than asphalt shingles, it pays off over time:
| Component | Average Cost (Per Sq. Ft.) |
|---|---|
| Metal Panels | $4 – $8 |
| Underlayment & Materials | $1.50 – $2.50 |
| Labor (Pro Install) | $3 – $7 |
Installing metal roofing yourself may save on labor but increases risk of costly mistakes. In most cases, it’s best to work with a licensed contractor like BCM Roofing to ensure long-term performance and warranty protection.
DIY or Hire a Pro?
Here’s a quick breakdown:
| Task | DIY Feasibility |
|---|---|
| Measuring/Cutting Panels | Moderate |
| Safe Ladder Use | High Risk |
| Flashing Installation | Advanced |
| Warranty Compliance | Often Requires Pro Install |
Unless you’re experienced with roofing, hiring a pro is usually the safer and more cost-effective choice—especially in a climate like Michigan’s.
