Mighty Buildings Roofing: The Fort Lauderdale Owner’s Guide
Mighty Buildings panelized roof sections in Fort Lauderdale typically cost $400 – $1,800 to repair and $8,000 – $20,000 for a full replacement, depending on how many panels have failed and whether the underlying framing is still sound. We keep common Mighty Buildings-compatible roofing fasteners, sealants, and panel clips on our trucks, so most single-panel repairs can be quoted and scheduled within one visit. Most owners discover the problem after a heavy South Florida downpour, when a brown stain appears on the ceiling or water starts beading along a wall seam that was dry the week before.

We’re an independent Fort Lauderdale contractor, not affiliated with Mighty Buildings. That matters because we’re not tied to any one supply line. If the original panel is discontinued or backordered, we can source a structurally equivalent panel and match the roof profile without making you wait six months.
Which Mighty Buildings Models This Applies To

Mighty Buildings uses a panelized roof system across their accessory dwelling unit and studio lines, including the Mighty House and Mighty Duo series. The roof panels themselves are a composite laminate, but the weak points are almost always the same regardless of model: the seam joints between panels, the edge flashing, and the fastener points where the panels tie into the wall system.
To identify your exact roof configuration, check the specification sheet from your original build or look for a label plate inside the mechanical closet or near the electrical panel. It’ll list the panel series and a build date. If you don’t have that paperwork, measure the panel thickness at the eave edge, it’s usually 4 to 6 inches for the roof assembly, and take a photo of the seam profile from inside the attic space if you have one. Bring that to the phone call and we can usually tell you whether it’s a first-generation panel or the current production run before we even schedule the visit.
On the OEM-vs-aftermarket question: for Mighty Buildings specifically, the sealant and flashing components are commodity items with excellent aftermarket equivalents. The structural panels themselves are proprietary, so if the panel core is cracked or delaminated, you’re looking at a factory panel or a custom-fabricated match. Most Fort Lauderdale failures we see are in the seam and flashing layer, not the panel core, which gives owners more repair options than they expect.
Styles & brands we work with







Signs Your Mighty Buildings Roofing Is Failing
- Water staining at the ceiling-to-wall junction. This usually means the seam tape or sealant at the panel edge has lost adhesion. In Fort Lauderdale’s humidity, that adhesive is fighting a losing battle after about eight to ten years.
- A soft spot when you press on the ceiling drywall. Water has been pooling above that spot long enough to break down the gypsum. By the time you feel softness, the leak has been active for weeks, not days.
- Daylight visible through the eave or ridge gap from inside an attic or crawl space. This means the edge flashing has pulled away from the panel, usually because the fasteners corroded. Salt air near Fort Lauderdale Beach accelerates this dramatically.
- Crumbling or cracked sealant beads along the exterior panel seams. Walk around the outside of your structure and look at the horizontal seams. If the sealant looks chalky, shrunken, or has visible cracks, water is already getting behind it.
- A musty smell inside that gets worse after rain. This is the early warning that often shows up months before visible staining. If your Mighty Buildings unit smells like a damp towel after every afternoon storm, don’t wait for the ceiling to discolor.

AfterReplacement Cost & What’s Included

For a Mighty Buildings roof repair in Fort Lauderdale, expect $400 – $1,800 depending on scope. A single seam re-seal with proper surface prep runs $400 – $900. Replacing damaged flashing at one eave edge typically lands between $600 and $1,400. If a panel core has delaminated and needs a custom-fabricated replacement, you’re looking at $1,500 – $1,800 for that single panel including installation.
A full roof replacement on a Mighty Buildings structure runs $8,000 – $20,000 in Fort Lauderdale. The spread is driven by unit size, how many panels are involved, whether the underlying wall-to-roof connection points need remediation, and whether we’re matching an existing roof profile or upgrading to a more weather-resistant seam system. Every quote includes parts, labor, disposal of the failed materials, and our written warranty on the work. We don’t give verbal ballparks. We write down the number before we pick up a tool, and that number is the number on the invoice.
“Tell me what you need, I’ll tell you what it costs, then we’ll get it done.” That’s how Trevor Nash runs every estimate at Penhallow Remodeling Fort Lauderdale, and it applies to a $600 seam reseal the same as it does to a full kitchen remodel.
DIY or Call Us?
Roofing work on any structure involves height, and Mighty Buildings units are no exception. If your repair requires getting on the roof or working from a ladder at the eave line, call us. The risk of a fall isn’t worth saving a few hundred dollars, and the panels get extremely slick when wet, which in Fort Lauderdale is most afternoons from June through October.
What you can safely do from the ground: photograph the exterior seams and any visible damage, mark the interior stain locations with painter’s tape so we can trace them to the source, and check whether your gutters are clear of debris. A clogged gutter pushing water back under the eave is a surprisingly common root cause of what looks like a roof panel failure. If you’ve done those checks and you still have a leak, call (754) 551-2922 and we’ll schedule a visit with a written repair scope.
FAQs

The panel core is designed for a 25-30 year service life, but the seam sealants and flashing in a Fort Lauderdale salt-air and humidity environment realistically need service every 8-12 years. Plan for a seam inspection by year eight, even if nothing looks wrong from the ground. Call (754) 551-2922 if you’re approaching that mark and want us to take a look.
Yes, in most cases. If the leak is at a seam or flashing point, a repair is straightforward and stays under $900. Panel core replacement is only needed when the composite itself has cracked or delaminated, which we see in fewer than one in five Fort Lauderdale service calls. We’ll always show you the failed area before recommending replacement, so you’re not guessing.
A single seam reseal or flashing replacement is usually a half-day job once materials are on site. A full panel core replacement takes one to two days including proper curing time for the sealants. We’ll give you a defined arrival window when we schedule, and a live person answers the phone 24/7 if you need to reach us before we arrive.
We stock the common consumables: seam sealants, flashing profiles, panel clips, and corrosion-resistant fasteners suited to coastal Florida. For proprietary panel cores, we order per job, usually with a one to two week lead time depending on availability. We’ll confirm stock status on your first call. Call (754) 551-2922 for a free estimate and we’ll get you on the schedule.
If your Mighty Buildings roof is leaking or showing signs of fatigue, don’t wait through another South Florida storm season. We also carry parts for KraftMaid cabinetry, Cambria countertops, and Silestone surfaces, so if your project scope grows beyond roofing, we can handle it under the same written-price and written-guarantee standard. Call (754) 551-2922 and ask for Trevor. You’ll get a straight answer about what it costs before anyone shows up with a ladder.
