Mobile Home Roof-Over Types in Tallahassee
A manufactured home roof is shallow and light, built in a factory to the federal HUD standard (24 CFR Part 3280), so a metal roof-over is planned around that frame. Most jobs fall into one of four kinds.
Single-Wide Roof-Overs
A single-wide roof is long, narrow and nearly flat, so each panel run is short and the job is small, which is why single-wides sit at the bottom of HomeGuide's range. Furring or purlins go through the old roof into the trusses, and the panels fasten to those. The details to watch are the ends of the home and any spot where a porch or carport roof butts against it.
- Cost range: $2,500 to $19,200 (HomeGuide)
- Panel choice: ribbed steel or aluminum; HomeGuide names aluminum as a popular mobile home material
Double-Wide Roof-Overs
A double-wide is two halves joined at the center, and the ridge sits on that seam. The roof-over has to bridge the joint with a continuous ridge cap and keep water out of the line where the halves meet. It's also more roof: HomeGuide's low end for a double-wide is twice the single-wide figure.
- Cost range: $5,000 to $32,000 (HomeGuide)
Built-Up Pitched Roof-Overs
Some owners add a framing system that raises the pitch, so water runs off faster and the attic space gets bigger. Purlin-mounted metal is a recognized system on Leon County's re-roof affidavit, but framing that changes the roof's shape is closer to structural work than to roofing. Florida counties don't all treat this the same way. Bay County's roof permit form, for example, requires an engineer's letter for any mobile home roof re-cover. Ask the City or Leon County permit office what they need before work starts.
Repairs on Original Metal Mobile Home Roofs
Some older homes still have a factory metal roof, often curved or nearly flat. Leaks there come from the same places as on any metal roof, fasteners, seams and rusted edges, and a repair or a coating can buy time when the home has only a few years left. See metal roof coating and metal roof repair.

Before a Manufactured Home Roof-Over in Leon County
A few things are worth checking before anyone climbs on the roof:
The data plate
Federal rules require a data plate inside the home showing the wind zone and roof load zone it was designed for. Leon County homes should be built for Wind Zone II.Roof-to-wall ties
In Wind Zone II, the federal standard calls for steel straps or engineered connectors at most 24 inches apart where roof framing meets the walls. A roof-over adds new fasteners into that framing, not new strength to those ties.Venting
Panels over a low roof with little attic space can trap heat and moisture. Ask how the quote vents the space under the new roof.Permit and approval
The panel needs a Florida Product Approval number like any other roof. See metal roof installation for what that number covers, and metal roof over shingles if your home already has asphalt shingles.
On a home in a park, also check the park's rules on roof color and work hours. And if the home is near the end of its life, a full roof-over may be worth less to you than a repair and a few more years.
