Mobile Home Roof Over: Is It Right for You?

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:

1. Evaluation – Structural assessment of existing home
2. Preparation – Secure loose roofing, install attachments
3. Framing – Build truss or rafter system
4. Sheathing (if used) – Install decking
5. Metal installation – Apply panels and trim
6. 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.
