Two Good Options, One Right Fit
When a mobile home roof reaches the end of its life, a roof-over is usually the smartest way forward, and the choice almost always comes down to TPO or metal. Both cover the existing roof with a fresh, durable surface, and both hold up far better than the tired coating or panels underneath. The real question is which one suits your home, your budget, and the Florida climate you live with every day. There are more mobile home roofing materials than these two, but TPO and metal are the ones owners actually weigh against each other.
How Each System Handles Water
Leaks are the reason most roof-overs happen in the first place, so it makes sense to start there. A TPO roof-over covers the whole surface in large sheets that are heat-welded together, which leaves very few seams for water to exploit, and the seams that do exist are fused rather than glued or fastened. Metal roof-overs shed water well too, but they rely on overlapping panels and fasteners, and every fastener and overlap is a spot that has to stay sealed over time.
In practice, both keep a home dry when they are installed correctly, and workmanship matters more than the material on this point. That said, the seamless nature of a welded TPO surface gives it an edge on a flat or low-slope mobile home roof, where standing water is more likely and there is less pitch to help panels drain. Owners who came to a roof-over after months of chasing a stubborn leak often feel that edge most.
Heat and Energy in the Florida Sun
Florida heat is relentless, and your roof is your first defense against it. A light-colored TPO membrane reflects a large share of the sunlight that hits it, which keeps the surface cooler and takes real strain off your air conditioning through the long summer. Metal is naturally reflective as well, especially in lighter finishes, though darker panels can absorb more heat unless they carry a reflective coating.
For most owners, both systems will feel like an upgrade over an old, sun-baked roof that had stopped reflecting anything. The difference tends to be modest, but on a home where cooling costs are already a concern, a reflective TPO surface is a dependable way to keep the interior comfortable without running the air conditioner harder than it needs to work.
Upkeep and Longevity
Neither of these systems asks much of you once it is installed, which is part of what makes a roof-over so appealing. A TPO surface generally needs little more than the occasional inspection and a clear path for drainage, and because there are so few seams, there is simply less to go wrong. Metal holds up for decades as well, though fasteners can loosen over the years and the sealant around penetrations needs an eye kept on it.
Both can give you many years of protection when the work is done right, and both far outlast the coatings and older panels they replace. The honest answer on lifespan is that installation quality and regular inspection matter more than the label on the material, which is exactly why the crew doing the work is as important as the system you pick.
Which One Suits Your Home
The best choice depends on the shape and slope of your roof, your goals for the home, and how long you plan to stay. TPO tends to be the natural fit for flat and low-slope mobile home roofs where a seamless surface and reflectivity carry the most weight. Metal appeals to owners who want a traditional look and do not mind the panels and fasteners that come with it.
Before any of that matters, though, it is worth being sure a roof-over beats another round of repairs for your situation. Once a roof-over is clearly the answer, the TPO or metal decision becomes much easier with a professional look at your actual roof, and the full picture of how a TPO roof-over works fills in the rest.

Reading through the trade-offs gets you most of the way, but the clearest answer comes from someone standing on your roof with your goals in mind. A written inspection tells you what shape the existing surface is in and which roof-over makes the most sense for your home and your budget.
