Types of Metal Roofing for Houses
Before learning How To Install A Metal Roof On A House, you must choose the right metal roof type.
Common Residential Metal Roof Types
| Type | Description | Best For |
|---|---|---|
| Corrugated panels | Wavy pattern, exposed fasteners | Sheds, budget homes |
| Standing seam | Hidden fasteners, clean look | Modern homes |
| Ribbed panels | Flat panels with ribs | DIY installations |
| Metal shingles | Look like asphalt or slate | HOA areas |
👉 This guide focuses on exposed-fastener panel systems, the most DIY-friendly option.
Tools and Materials You’ll Need
Essential Tools
- Drill/impact driver
- Metal cutting snips or circular saw (metal blade)
- Tape measure
- Chalk line
- Roofing hammer
- Ladder and roof harness
Materials
- Metal roofing panels
- Roofing underlayment
- Synthetic ice & water shield
- Roofing screws with neoprene washers
- Ridge cap
- Drip edge and flashing
- Closure strips (foam)
Step 1: Check Building Codes and Permits
Before starting:
- Confirm local permit requirements
- Verify wind uplift and snow load ratings
- Check fire-resistance codes
Some jurisdictions require inspection even for DIY installations.
Step 2: Inspect and Prepare the Roof Deck
A solid foundation is essential.
Roof Deck Checklist
- Remove old shingles (recommended)
- Replace rotted plywood
- Ensure deck is flat and secure
- Hammer down raised nails
💡 You can install metal over shingles in some areas, but removal is best for longevity.
Step 3: Install Underlayment and Ice Barrier
Underlayment protects against moisture and condensation.
Installation Order
- Ice & water shield (eaves and valleys)
- Synthetic roofing underlayment
- Overlap seams by 4–6 inches
Secure underlayment using cap nails or staples.
Step 4: Install Drip Edge and Eave Trim
Drip edge directs water away from fascia and foundation.
Best Practices
- Install eave trim first
- Overlap sections by 2 inches
- Secure every 12–16 inches
Step 5: Measure and Plan Panel Layout
This step determines how professional your roof looks.
Layout Tips
- Measure roof width carefully
- Snap chalk lines for straight alignment
- Start from the squarest corner
- Plan overlaps before fastening
⚠️ Crooked first panels cause problems across the entire roof.
Step 6: Install Metal Roofing Panels
Now the main work begins.
Panel Installation Steps
- Place first panel square to roof edge
- Align bottom edge with eave trim
- Secure with roofing screws:
- At flat sections, not ridges
- Every 12–18 inches
- Do not overtighten screws
- Overlap next panel as specified
🔩 Screws should compress washers slightly—not flatten them.
Step 7: Install Side and End Overlaps Correctly
Proper overlaps prevent leaks.
Overlap Guidelines
- Side lap: at least 1 rib
- End lap: 6–8 inches (sealant recommended)
Use butyl tape or roofing sealant in end laps for added protection.
Step 8: Install Flashing Around Penetrations
Roof penetrations are common leak points.
Areas That Require Flashing
- Chimneys
- Vents and pipes
- Skylights
- Wall intersections
Use rubber pipe boots and metal flashing designed for metal roofs.
Step 9: Install Ridge Cap and Closure Strips
The ridge cap seals the roof peak.
Ridge Installation Steps
- Install foam closure strips
- Place ridge cap centered over peak
- Secure with screws every 12 inches
Ensure proper ventilation if using a vented ridge system.
Step 10: Final Sealing and Inspection
Before finishing:
- Inspect all screws
- Check flashing overlaps
- Seal exposed fasteners if required
- Clean metal shavings (prevent rust stains)
A careful final inspection ensures decades of performance.
Common Mistakes to Avoid
❌ Overtightening screws
❌ Skipping underlayment
❌ Installing panels out of square
❌ Cutting metal without protection
❌ Ignoring thermal expansion
Avoiding these mistakes significantly extends roof life.
How Long Does It Take to Install a Metal Roof?
| Installer | Time Estimate |
|---|---|
| DIY beginner | 4–7 days |
| DIY experienced | 2–4 days |
| Professional crew | 1–2 days |
Weather conditions can impact timelines.
