Can I increase the ceiling height in my mobile home?

No. Your roof is built to minimal height standards for cost, insulation, travel height, wind handling, etc. You basically have ceiling joists, a relatively small space for insulation, and the roof. There's no extra height available there. You will need to raise the upper roof surface to make room for livable space below.

Here's a short list of things that need to happen to raise the roof in part or all of your home:

• Roof demolition
• Wall framing
• Roof framing
• Plumbing vent extension (if present)
• Utility vent/flue extension (if present)
• Roofing repair (shingles or membrane, edge flashing, penetration flashing)
• Electrical wiring extension/reconfiguration
• Wall and roof insulation & vapor barrier
• Exterior siding & soffit
• Drywall hanging and taping
• Wall and ceiling texture and painting
• Building permits
• Inspections

Whether this project is appropriate for you is entirely a matter of prerogative, budget and legality and not ours to say.

One other consideration is that mobile homes tend to be subject to wind damage (tipover). Raising the height of yours exacerbates that problem.

I lived in a mobile home for 4 years in the 1970s. Based on this I think you should not attempt to raise the roof in a 7 ft section. The original structural integrity would be called into question. You would probably reduce the resale value.

Much depends on your situation (park lot rental .vs. own land, very different) but I will guarantee that building an add-on room with more height (and more space, yay!) would be far less trouble and expense than trying to "raise the roof" on a mobile home. The structure is already "just barely adequate" and modifying it is a huge undertaking for minimal benefit.

If you own the land you are on, it can be quite practical to build enough real house (a piece you can afford at a time) that you can eventually sell the mobile part and have it towed away. If you don't own the land that's not remotely practical.

Otherwise, flip the bedroom and the living room functions. Or pull up a flatbed trailer and build a "tiny house" on that with the headroom you want for your bedroom, and either or both parts can be towed away to a new site as needed.

Of course you can raise the roof. Given unlimited budget you can raise the roof, install marble floors, and have a fireplace on each end.

Is raising the roof on a mobile home a good idea? F@@k no.

Honestly it is a good thought. I grew up part of my life in a mobile home and grandmother owned a mobile park. I get the ceiling issue. But most of these (all almost)have specific weldings for the roof load. But these "beams" also give lateral support to the walls - these are enclosed units.

Example - On older homes not taken care of they may develop rust. If the rust hits the support beams/crosses we would have to weld a new piece of metal - usually outside. The detachment due to rust would cause the home to become "wavy" and move when walking. Eventually the movement causes other supports to wear and welds/screws/bolts to loosen and home is done. (newer mobile homes have the same issues but hide these joints better which make them look better but also harder to repair)

Isherwood has a list of things. What it is not explaining well is the lateral load the roof is holding. This means to add height you will have to attach that to something - which means creating all new walls along the perimeter or some really expensive metal beams (plus welding). So to summarize you are basically building a house inside your mobile home - so why not just build a house?

Can be done, but would basically require building that whole bedroom over with 8' (or taller) studs and putting up a new roof over it. That would be the best for retaining structural integrity and would also make the mobile.home safe to move in the future Any other method of extending the ceiling is asking for trouble.... like a roof collapse.
