A roof-over (also called a re-roof or cover-up) installs a new roof system directly over your existing mobile home roof. It's a popular option, but is it right for you?
What Is a Mobile Home Roof-Over?
A roof-over involves building a new roof structure on top of your existing mobile home roof:
- New trusses or rafters attached to existing structure
- Creates pitched roof over flat or low-slope original
- Metal panels installed over new framing
- Improves appearance and performance
Benefits of Roof-Overs
Insulation Improvement:
The air gap between old and new roofs adds insulation value. Combined with added insulation, this can significantly reduce cooling costs.
Leak Prevention:
A properly installed roof-over creates a completely new weather barrier, eliminating ongoing leak issues with deteriorated original roofs.
Appearance Upgrade:
Transform a flat mobile home roof into an attractive pitched roof that looks more like a site-built home.
Structural Protection:
The new structure shields the original roof from UV degradation, extending its life and protecting interior components.
Noise Reduction:
The dead air space dramatically reduces rain noise compared to direct metal roofing.
Drawbacks to Consider
Added Weight:
Roof-overs add 2-4 pounds per square foot. Your home's structure must handle this load—have it evaluated first.
Hidden Damage:
Installing over an existing roof means any underlying problems remain hidden. If your decking is rotted, a roof-over doesn't fix it.
Height Changes:
The raised roofline may affect:
- Awning and carport clearance
- HVAC system venting
- Park height restrictions
Cost:
Roof-overs typically cost $8,000-$15,000 depending on size and materials—more than coating, less than complete replacement.
Roof-Over vs Other Options
| Option | Cost | Lifespan | Insulation | Appearance |
|--------|------|----------|------------|------------|
| Coating | $2,000-4,000 | 10-15 years | Minimal | Same |
| Roof-Over | $8,000-15,000 | 30-40 years | Good | Improved |
| Complete Replacement | $12,000-25,000 | 40+ years | Best | Best |
Is Your Home a Candidate?
Roof-overs work well when:
- ✓ Existing structure is sound
- ✓ Original roof is leaking but not rotted
- ✓ You want long-term solution
- ✓ Energy efficiency is important
- ✓ Appearance matters
Roof-overs may NOT be right when:
- ✗ Significant structural damage exists
- ✗ Home isn't properly leveled
- ✗ Park has height restrictions
- ✗ Budget is very limited
Materials and Options
Metal Roofing:
Most roof-overs use metal panels for durability and light weight. Options include:
- Screw-down panels (economical)
- Standing seam (premium)
- Stone-coated steel (tile appearance)
Insulation:
Adding insulation during installation maximizes energy savings:
- Fiberglass batts in truss cavities
- Rigid foam board under metal
- Radiant barrier facing airspace
Installation Process
A typical roof-over takes 2-5 days:
- Evaluation – Structural assessment of existing home
- Preparation – Secure loose roofing, install attachments
- Framing – Build truss or rafter system
- Sheathing (if used) – Install decking
- Metal installation – Apply panels and trim
- Finishing – Seal penetrations, install gutters
Choosing a Contractor
Mobile home roof-overs require specific experience:
- Verify Florida contractor license
- Ask about mobile home experience specifically
- Request references from similar projects
- Get detailed written scope of work
- Confirm permit requirements in your area
Our Recommendation
For mobile homes with chronic leak issues but sound structure, roof-overs offer excellent long-term value. The combination of leak protection, energy savings, and improved appearance justifies the investment for most owners.
