Step-by-Step Installation Process
1. Planning & Measurement
Accurate roofing measurements do more than estimate material needs—they reduce waste and installation errors. Adding a 10% buffer is recommended during order. roof-skylight.com
2. Remove or Overlay Existing Roofing
Evaluate whether overlaying shingles is safe. Removal is advisable if the old roof is damaged or waterlogged. Today's Homeowner
3. Install Underlayment & Flashing
Install moisture-resistant underlayment on the deck and edge flashing around eaves and rakes to channel water away and prevent leaks. Origin Roofing and Exteriors
4. Lay Metal Panels
Align panels square to the roof line, overlap as recommended, and fasten securely. Standing seam panels often snap together, while corrugated and rib panels rely on exposed screws. roof-skylight.com
5. Add Flashing & Ridge Components
Finish with flashing at ridges, hips, and valleys. Use sealant tape and closure strips before applying ridge caps, ensuring tight seals at seams. CMT Components
6. Inspect & Seal All Fasteners
Check that fasteners are perpendicular and seal washers are properly seated. Apply additional sealants like butyl tape where metal contacts metal to prevent leaks. familyhandyman.com
7. Final Inspection & Cleanup
After installation:
-
Remove debris and protect landscaping
-
Inspect flashing, seams, and fasteners for tight seals
-
Address any exposed fasteners or gaps
Checklist: Choosing a Metal Roofing System
Choose the panel type (standing seam, corrugated, etc.) based on aesthetics, durability, and budget
Verify compatibility of roofing material with local climate (e.g., steel vs. aluminum)
Ensure underlayment and flashing adhere to code or manufacturer specifications
Confirm proper fastener spacing, type, and sealant use
Check slope and deck type to match installation method
Confirm warranty compliance by following installation details exactly
Maintenance & Best Practices
-
Inspect annually for loose screws, sealant wear, or debris accumulation
-
Clear gutters and valleys to prevent water backing up under roofing
-
Touch-up coatings or sealants when scratches or exposed metal appear
-
Check for oil canning, especially in expansive panels, and consult installer solutions if needed
