Mobile home roofing in Tampa Bay: roof-overs and permits

Tampa Bay has more manufactured-home communities than almost any metro in Florida: the 55-plus parks along Ulmerton Road and Belcher in Largo, the co-ops in Pinellas Park, the parks off US 301 and Big Bend Road in Riverview and Ruskin, the river communities in Hillsborough’s south county. Their roofs are a category of their own. The framing is lighter, the original covering was often a seamed metal pan or a thin shingle over 2x2 trusses, and the fixes the trade offers, roof-overs above all, do not exist for site-built houses. This guide is what a manufactured-home owner should know before the first quote.

Mobile home or manufactured home

The date on the HUD label decides a lot. A home built before June 15, 1976 is a “mobile home” built to no federal standard; a home built on or after that date is a “manufactured home” built to the federal HUD code (24 CFR Part 3280), with a red HUD certification label on the exterior and a data plate inside. Insurers, lenders and, sometimes, the permit desk treat the two differently, and a pre-1976 roof is usually the harder case. Find the label before you call; the contractor will ask.

Roof-over, or replacement

A roof-over comes in two kinds, and the quote should say which. A structural roof-over is a new, self-supporting roof built above the existing one: an insulated aluminum or steel panel system on its own posts, beams and framework, attached to the home only at the flashing, so its weight goes to the ground rather than onto the home’s trusses. The old roof stays. The appeal is real: no tear-off, added insulation, a pitched roof that sheds water where the old flat pan pooled it, and no new load on the home’s own framing. A recover is different: a single-ply membrane (TPO) over rigid insulation, or a coating system, laid over the existing roof and fastened through it to the home’s roof deck. It is lighter and cheaper than a structural roof-over and it stops leaks on a sound flat roof, but the existing deck and trusses carry all of it; ask what it adds in pounds per square foot and whether the home’s roof structure was built for it.

A replacement removes the covering down to the deck or the trusses and re-covers it, usually with shingles on a home that has a pitched, sheathed roof. It is the right answer when the deck is rotten, when the home already has a shingle roof in good structural shape, or when the park’s rules or the home’s height limit rule out a roof-over.

The state’s manufactured-home guidance has long held that a structural roof-over must be independent and self-supporting, attached to the home only at the flashing, unless it was engineered to tie into the home’s structure. A panel roof screwed through the old roof into the trusses and called “self-supporting” is neither, and it is where the leaks and the failed inspections come from; a recover, by design, is fastened through the deck and should be described and engineered as one.

The rules on who may do the work

Two Florida statutes and the local building department all have a say:

• Section 320.8249 requires a state mobile-home installer license (issued by the Department of Highway Safety and Motor Vehicles) for anyone who installs a manufactured home: setting, blocking, tie-downs. Hillsborough County’s checklist says mobile-home setup permits must be pulled by a licensed installer.
• Section 320.8245 limits alterations to a manufactured home after it leaves the factory and voids the manufacturer’s warranty on an altered item unless the work is done by a “qualified person,” which the statute defines as someone who meets the local licensing or competency requirements for that skill.
• The roofing license. A roof-over or a re-roof is roofing work, and Florida licenses roofing contractors statewide (a CCC number, or RC for a registered one) through the DBPR. Some roof-over systems are also installed by aluminum contractors licensed for that structure in Pinellas or Hillsborough. Ask which license the contractor is pulling the permit under, and check it.

What this means on the phone: an installer license is for setting the home, not for its roof; a roofing or aluminum license is for the roof; and the permit desk decides which it will accept for the system being proposed.

The permit

A roof-over or a roof replacement on a manufactured home needs a building permit from the same office that permits site-built houses: the City of Largo, Pinellas Park, Pinellas County for the unincorporated parks, Hillsborough County for Riverview, Ruskin, Gibsonton and the south county. The home itself is governed by the HUD code, but the roof-over is a structure built on site to the Florida Building Code and the site’s design wind speed, and Pinellas designs to 145 mph everywhere. Expect the permit to want the manufacturer’s engineering for the panel system, the fastening schedule, and an inspection before the panels close it up.

A contractor who says a roof-over “doesn’t need a permit on a mobile home” is telling you something about the contractor.

The park and the insurer

Two more parties get a vote. The park’s prospectus or rules commonly limit roof height, overhang and color, and some require the park office to approve exterior work; get that in writing before the deposit. Insurers write manufactured homes on their own policy forms, and many ask for the roof’s age, material and, on older homes, a photo or an inspection; a documented roof-over with a permit and a final inspection is what makes the next renewal easier.

What to ask before you sign

1. Which license number is on the permit, and is it a roofing, aluminum or installer license?
2. Is the roof-over self-supporting, and can I see the engineering for this panel system at my wind speed?
3. What happens to the old roof’s leaks and soft spots: are they repaired, dried, or simply covered?
4. What is the added weight, and has anyone looked at the piers and tie-downs?
5. What does the park require, and who submits it?
6. Is the price a fixed quote in writing, and what does the warranty cover: the panels, the workmanship, both?

Have this ready

• The HUD label number and the home’s year and size
• Photos of the current roof from the ground and, if it is safe, from a ladder
• The park’s rules on exterior work
• The insurer’s letter, if the roof came up at renewal

Licensing and permit rules are summarized from the statutes and the counties’ published guidance as of September 2026; the building department that issues your permit has the final word, and the contractor is responsible for the license, the permit and the engineering.
