Florida is hard on roofs in a way most of the country is not. The sun runs year round,
the salt reaches further inland than people expect, and the rain does not fall so much as
arrive sideways. On a manufactured home all of that lands on a lighter structure with a
thinner deck and a shallower pitch — so the roof you choose matters more here, not less.
There are three systems worth considering. Each one is genuinely the right answer in
some situations and the wrong answer in others.
Start with the slope, not the material
Before comparing brands or prices, look at the pitch of your roof. It decides which
systems are even eligible.
Most manufactured homes are flat or very low slope. Water does not run off a roof like
that — it sits, sometimes for hours after the storm has passed. Anything that works by
shedding water down a slope, shingles included, is the wrong tool. On a low-slope
roof you need a system that seals rather than sheds.
If your home has a genuine pitch — some newer double-wides do — the field opens up and
shingles become a reasonable option again.
TPO: the default for flat and low-slope
TPO is a single-ply membrane rolled out across the roof and heat-welded at the seams.
Welded, not glued: the laps are fused into one continuous surface, so there is no adhesive
to fail and no lap for standing water to work under.
Two things make it suit Florida. It is bright white, so it reflects a serious amount of
heat that would otherwise land in your ceiling. And it does not care about ponding water,
which is the failure mode that kills most low-slope roofs down here.
The catch is that TPO is only as good as the welding. Heat, travel speed and roller
pressure all have to be right for the conditions on the day. A bad weld looks identical to
a good one from the driveway and fails anyway — which is why we probe every seam by hand
before we leave.
Metal: the long game
A metal roof-over goes on above the existing roof, so there is no tear-off and no day
where your home sits open. Done properly it will outlast most of the alternatives by a
wide margin and stands up to wind better than anything else we install.
The thing to check is weight. The trusses under a manufactured home were engineered for
a specific load, and stacking a heavy second layer on a frame that was never designed to
carry it is a real risk. A lightweight metal system solves that; a heavy one does not.
Anyone who does not raise this with you has not thought about your home specifically.
Shingles: right look, right roof
Architectural shingles rated for Florida wind zones keep the traditional neighbourhood
look that a lot of parks prefer, and they are usually the friendliest on budget.
They belong on a pitched roof. If your roof is flat or nearly flat, no shingle — and no
warranty — will save you, because the system depends on gravity moving water off the
surface. If a contractor offers to shingle a low-slope manufactured home, that is the
moment to get another opinion.
What actually decides how long it lasts
Material choice matters less than most homeowners expect. What separates a roof that
lasts from one that leaks at year three is almost always the detail work:
- Fastening schedule. Manufactured decks are thinner and the framing
sits on different centres. Fasteners spaced for a site-built house can miss structure
entirely. - Underlayment and flashing. Leaks start in valleys, at pipe boots and
against walls — almost never in the open field of the roof. - Edge metal. Wind gets under a roof at the edge. That is where uplift
begins, and where a cheap trim detail shows up as damage after the first real storm.
Questions worth asking any roofer
- Is my roof genuinely suited to the system you are quoting, and why?
- What is the fastening schedule for my deck specifically?
- Will the roof be dried in the same day you tear off?
- Can I see the product approval and the licence in writing?
- Who is actually on my roof — your crew, or a subcontractor?
If the answers are vague, keep shopping. A roofer who works on manufactured homes every
week will have specific answers to all five.
