Rodent Exclusion in Fort Lauderdale, FL

The single most important closure on a Fort Lauderdale tile roof is the bird stop, also called the eave closure, a code-approved metal strip that fills the open course under the first row of barrel tile. It is typically 26 gauge galvanized steel or aluminum, sometimes ventilated with weep holes so the roof can still drain and breathe, and the Department of Energy names bird stopping among its recommended measures for clay and concrete tile roofs.

The reason it matters is the shape of the tile. A barrel tile sits on the deck as an arch, and under each arch at the eave there is a void as tall as the tile profile. With a bird stop fitted, that void is closed. With the bird stop missing, corroded through by salt air, or knocked out of place by a storm or a roofer, the void runs the whole length of the eave, and a roof rat can walk into the attic anywhere along it without chewing a thing.

The comparison that decides most quotes is a fitted metal closure against a bead of expanding foam. Foam is what a cheap exclusion line usually means. It is chewed out in a night, it traps moisture against the deck, and it has no place in a coastal tile roof. A manufactured bird stop is cut to the tile profile, fastened to the deck or the fascia, and lasts as long as the fascia does. Ask whoever attends which one is on the quote. The roof rat removal page explains why the eave is the first place the animal tries.

A complete exclusion on a Broward lot covers eight places in order: the tile eave, the soffits, the ridge, the fascia, the roof penetrations, the walls at grade, the trees, and on a canal property the rear edge along the sea wall and dock. Each one has its own material and its own way of failing.

Soffit rescreen

Original soffit screens on houses from the 1920s through the 1960s tear, rust and pull away from the frame, and aluminum soffit panels get pushed up from below. The fix is quarter-inch galvanized hardware cloth fastened behind the vent, or full panel replacement where the frame has gone.

Ridge vent screening

Ridge caps on a tile roof sit over an open slot that vents the attic, and many were laid with plastic mesh or nothing under them. Metal screening under the caps keeps the vent working and closes the slot to rodents.

Fascia gaps

Sun and salt air shrink the fascia board away from the roof deck over decades, opening a slot along the top edge. Sheet metal flashing or a ripped wood filler closes it for the full run, and painting it after keeps the wood from opening again.

Vent boots and line-set penetrations

Plumbing vent boots crack in the sun, and the hole cut for the AC line set is nearly always oversized and stuffed with foam. New boots, a metal escutcheon plate and a sealant rated for exterior use close both.

Tree-limb clearance to six feet

Fronds and limbs within about six feet of the roofline are the bridge onto the tile. Royal, queen, sabal, Washington, date and coconut palms, and mango, avocado, citrus, guava, sapodilla and starfruit trees all get flagged for trimming as part of the exclusion, because a closed roof with a ladder against it is still being tested every night.

Dock line and sea wall

On a canal lot the animals travel the sea wall cap, the dock line and lift cables and shelter in the hedge along the wall or under the dock apron. The inspection notes coiled rope, stored fenders, fallen fruit along the wall and Norway rat burrows behind it, and the written findings tell you what to clear. The neighborhood page for Rio Vista shows how this plays out on a mixed-era canal street.

A house needs exclusion when the traps keep filling, when the noise returns a few weeks after it stopped, or when daylight shows through the eave from inside the attic. Repeat activity is the clearest sign that the doorway was left open.

• Trapping that catches animals for weeks with no drop-off in the count
• Activity that stops after a treatment and returns within a month or two
• Greasy rub marks around the eave, a soffit corner or a vent frame, where a coat has passed many times
• Chewed soffit edges, torn screen, or bird stops visibly missing or rusted along the eave
• Daylight visible from inside the attic at the eave, the ridge or a gable
• Droppings on the sea wall cap, the dock or the boat lift beams, showing the route in use
• Fronds or limbs resting on the tile, with worn bark or frond stems along the route

The inspection that finds these is free, and it produces a map of openings instead of a guess. Book it through the rodent inspection page or call. Someone picks up the line day and night.

Galvanized hardware cloth, sheet metal and manufactured bird stops hold against a roof rat, and expanding foam, steel wool on its own, caulk and plastic mesh do not hold. The material choice is what separates a sealing job that lasts from one that gets redone next season.

The quarter inch is the standard because of what fits through it. UF/IFAS puts a mouse through a quarter-inch opening and a rat through a half-inch one, and sets a quarter inch as the rat-proofing figure so the smaller animal governs the mesh size. Bait has no role in exclusion at all: the EPA restricts second-generation anticoagulants to tamper-resistant stations in residential settings, and a poisoned rat behind a freshly sealed eave dies in the attic. Sealing plus trapping is the sequence, and the removal page lays out the trapping half.

Repair them now, in the same program as the trapping, because every chew-in is a marked route with the animal's scent on it and the next rat off the sea wall or the palm will find it within weeks. Trapping alone on an open roofline is the pattern behind nearly every multi-month story in homeowner forums.

The order within the program matters too. The contractor we route closes everything except the main active opening, sets traps on the runs inside, and closes the last opening with a one-way door or once the traps go quiet, so nothing is sealed in and nothing new gets in. Roof rats are wary of new objects, per UF/IFAS, so the traps stay in place for at least a week before anyone judges them, and the closures stay in place for good.

Putting off the sealing also delays the one part of the job a warranty can attach to. Ask whoever attends what terms cover the closures, whether the term is a single period or renews, and what a return visit costs if activity comes back. The about page lists what the routed contractors are expected to state in writing.

A closed building keeps rats out permanently, and nothing sold in a bottle, a plug-in device or a bait station does the same job. Permanent means every opening a quarter inch or larger closed with metal, the trees cut back six feet from the roof, and the food and harborage at the rear of the lot managed.

Three habits keep a sealed Fort Lauderdale house sealed. Walk the eave from the ground twice a year and after any storm, looking for a displaced tile or a bird stop that has dropped. Keep fronds and limbs trimmed to six feet from the roofline, and pick up fallen mango, avocado, citrus and starfruit. On a canal lot, stow rope and fenders, keep the hedge along the sea wall off the ground, and glance at the dock beams and the wall cap for droppings.

None of this changes what the neighbors do. UF/IFAS gives the roof rat a range of around 150 yards from its den, so the food supply can be three lots away while your roof is the nest site. That is why the closures, and only the closures, are the part you fully control.

Full-home exclusion runs $500 to $2,500 in HomeGuide's 2026 national data, and a Fort Lauderdale tile roof tends to land toward the upper part of that band because the whole eave has to be closed, tile by tile, from one end to the other. These are national typical-job bands; the free inspection produces the itemized local number.

What moves an exclusion quote inside the band is mostly linear feet and count. The length of tile eave that needs a bird stop is the biggest single driver. The number of vents, soffit returns and penetrations found open comes next, then the state of the fascia, since a board that has shrunk away from the deck along an entire run is a longer job than one gap. Two-story houses and steep tile add ladder and lift time. In the other direction, the national guides price crawl-space and basement work that a slab-on-grade Broward house does not have, so a local quote for a shingle roof can come in under the national spread for the same scope. Ask that the exclusion be its own line, and ask what the warranty terms on it are before you compare bids.

Fort Lauderdale exclusion work is shaped by three local facts: the age of the single-family belt east of US-1, the storm season that runs June through November, and the state credential the contractor has to hold. Each changes what a good quote looks like.

Where the original fascia and screens are

Victoria Park was platted in the 1920s and holds a large share of the city's historic houses. Poinsettia Heights carries 1920s stock, Rio Vista mixes 1940s to 1960s homes with 1920s Mediterranean Revival, Coral Ridge is mid-century, and the Lauderdale Isles and Las Olas Isles are canal-front. Across all of them the fascia, soffit screens and often the tile are original, so an exclusion on these streets is longer and more thorough than on a newer block-and-stucco house farther west. The neighborhood pages for Victoria Park and Coral Ridge go into the specific roof types.

After a hurricane or a flood

Wilma in 2005 and Irma in 2017 both crossed Broward, and the April 2023 flood put record rainfall on Fort Lauderdale in a single day. Storm damage undoes exclusion by mechanism: wind lifts tiles and tears soffits, one broken tile cascades into the next as the Department of Energy documents, debris piles become harborage, and floodwater drives rats to high ground and attics. The CDC connects leptospirosis case increases to hurricanes and floods, names rodents among the reservoirs, and advises rodent control as post-flood prevention. A post-storm rodent inspection re-checks every closure after the weather passes.

The credential and what to check

Exclusion by itself is construction work, but it is almost always sold with trapping, and trapping rats or mice in, on or under a structure for hire in Florida requires at minimum an FDACS Limited Commercial Wildlife Management certificate. Any rodenticide on the job calls for an FDACS pest control business license with a certified operator in General Household Pest and Rodent Control. FWC does not license rat and mouse trappers. Every contractor we route holds the FDACS credential the job needs, and the license number can be checked with FDACS before work starts.

1. Confirm the FDACS license number in the state lookup.
2. Get exclusion, trapping, cleanup and any monitoring plan as separate lines.
3. Ask for the closure list: each opening, its location, and the material used.
4. Ask whether the eave gets a fitted bird stop, and get the answer in writing.
5. Ask what warranty terms cover the closures and how many return visits are included.

Send those questions through the contact page ahead of the visit if you want them answered first.

A Broward rodent job is a sequence of separate lines, and these are the pages that cover the steps on either side of this one.

• Roof Rat Removal: Trapping out the roof rat that runs the sea walls and rooflines of Broward, sequenced with sealing.
• Rodent Inspection: A free walk of the roofline, attic, exterior and dock line that sets the order of the job.
• Post-Storm Rodent Inspection: A roofline and harborage check after a hurricane or a flood, before the winter attic noise starts.

How the pieces fit together, and which license to look up, is covered on the about page. The contact page has the hours and the office address.
