Types of Metal Roofing for Houses
Before learning How To Put A Metal Roof On A House, it’s important to choose the right roofing style.
Common Residential Metal Roof Options

👉 This guide focuses on exposed-fastener metal panels, which are the most DIY-friendly and cost-effective.
Tools and Materials You’ll Need
Essential Tools
- Drill or impact driver
- Tin snips or metal-cutting saw
- Tape measure
- Chalk line
- Hammer
- Ladder and safety harness
Required Materials
- Metal roofing panels
- Synthetic roofing underlayment
- Ice and water shield
- Roofing screws with neoprene washers
- Drip edge and flashing
- Ridge cap
- Foam closure strips
Having everything ready before starting saves time and prevents mistakes.
Step 1: Check Local Codes and Permits
Before installing a metal roof:
- Check local building codes
- Verify wind and snow load requirements
- Confirm whether a permit is required
Some areas require inspections even for DIY roofing projects.
Step 2: Inspect and Prepare the Roof Deck
A solid roof deck is critical.
Preparation Checklist
- Remove old shingles (recommended)
- Replace any rotted plywood
- Secure loose decking
- Ensure the surface is flat
💡 While metal roofing can sometimes be installed over shingles, removing old roofing allows proper inspection and improves long-term performance.
Step 3: Install Ice & Water Shield and Underlayment
Underlayment protects the house from moisture and condensation.
Installation Order
- Ice & water shield along eaves and valleys
- Synthetic roofing underlayment over the entire roof
- Overlap seams by 4–6 inches
Fasten underlayment with cap nails or staples.
Step 4: Install Drip Edge and Eave Trim
Drip edge directs water away from the fascia and foundation.
Best Practices
- Install eave trim first
- Overlap pieces by 2 inches
- Fasten every 12–16 inches
This step is often skipped, but it greatly improves water control.
Step 5: Plan the Metal Panel Layout
Proper planning ensures a professional-looking result.
Layout Tips
- Measure roof width and length carefully
- Snap chalk lines for straight alignment
- Start from the squarest corner of the roof
- Dry-fit panels before fastening
⚠️ A crooked first panel will throw off the entire roof.
Step 6: Install the First Metal Panel
The first panel is the most important.
Installation Steps
- Align panel square with the roof edge
- Let it overhang the eave trim slightly
- Secure using roofing screws:
- Place screws on flat sections
- Space screws 12–18 inches apart
🔩 Tighten screws until the washer compresses slightly—do not overtighten.
Step 7: Install Remaining Metal Panels
Continue installing panels across the roof.
Panel Overlap Guidelines
- Side overlap: 1 full rib minimum
- End overlap: 6–8 inches
Apply butyl tape or sealant at end laps for added leak protection.
Step 8: Cut Panels and Fit Around Roof Features
Most roofs have penetrations that require precise cutting.
Common Penetrations
- Plumbing vents
- Chimneys
- Skylights
- Exhaust pipes
Use rubber pipe boots and metal flashing designed specifically for metal roofs.
Step 9: Install Ridge Cap and Closure Strips
The ridge cap seals the peak of the roof.
Ridge Installation Steps
- Install foam closure strips on both sides
- Center the ridge cap over the peak
- Secure with screws every 12 inches
Ensure proper ventilation if using a vented ridge system.
Step 10: Final Inspection and Sealing
Before considering the job complete:
Final Checklist
- Inspect all fasteners
- Check flashing and overlaps
- Remove metal shavings (prevents rust stains)
- Seal exposed fasteners if required
A careful final inspection can add years to your roof’s life.
Common Mistakes to Avoid
❌ Overtightening screws
❌ Skipping underlayment
❌ Installing panels out of square
❌ Ignoring thermal expansion
❌ Poor flashing around penetrations
Avoiding these errors is just as important as following the steps correctly.
