A small, slow leak
A slow drip around flashing or a plumbing vent can wet the same patch of insulation for weeks. It often means a smaller opening up front and a larger moisture problem later, so the question is how long it has been going on.
What happens inside the house after a roof leak: temporary tarp, wet insulation and ceilings removed, and drying before repairs.

A roof leak soaks attic insulation first, then the ceiling below it. The crew can tarp the opening, remove wet insulation and drywall, and dry the rest with meters and dehumidifiers. Port St. Lucie Water Damage Restoration answers 24/7. Roof replacement itself goes to a roofer, and a crew is dispatched as fast as one is available.
The roof is the first part of a Florida house that a storm tests, and in Port St. Lucie that test comes often, with daily thunderstorms through the wet season and the occasional tropical system. A lifted shingle, a cracked tile, dried-out flashing around a vent pipe or a pool-cage anchor can all let in water without any hole you can see from the ground.
The part that surprises people is where the damage ends up. Water from a small roof opening runs along a rafter or a truss, soaks the insulation, and drips onto a drywall ceiling several feet from the entry point. By the time a brown stain appears, the attic has been wet for a while, and the mold clock the EPA describes, 24 to 48 hours for drying, may be well along.
This page covers the interior side: what to do about the ceiling, the insulation and the walls below the leak, and how a temporary tarp buys time. It does not cover replacing a roof, and a crew does not do roofing. A roofer or licensed contractor makes the permanent repair, and the sooner the opening is closed, the sooner drying means something.
A roof leak usually shows up or grows after rain, often a few feet from the actual entry point. An A/C or plumbing leak tends to show up on dry days. Checking the attic insulation, the roof deck and the stain's pattern after the next rain usually separates the sources.
Roof leaks follow weather. If the stain grows within a day or so of a storm and stops growing in dry spells, the roof or an exterior opening is the likely source. If it is darker around an air handler or under a bathroom, other causes are in play.
In Florida attics, the A/C air handler, its condensate pan and the drain line are common sources too, so a stain is not always the roof. The A/C condensate page explains how to tell, and the ceiling water damage page covers drywall repair. Sometimes it is both, which is why the first visit is measuring rather than guessing.
No. The crew can place a temporary tarp to keep rain out and then handle the interior water damage. Roof repair or replacement is work for a roofer or licensed contractor, and Florida requires licensed contractors for building work, so check any roofer's licence on DBPR's website.
A tarp is a stopgap. It is held down with battens or sandbags and is not meant to last through a season of Florida storms. Plan to have a roofer look at the roof soon after.
If you hire a roofer, ask what the tarp is attached to and who removes it. A good handoff means the roofer sees the damaged area, the crew sees the interior, and nobody waits on the other to start.
Wet insulation holds water against the ceiling drywall and the roof framing, and in humid Florida air it can stay damp for days. It also sags and stops insulating, which makes the A/C work harder. Insulation that stayed wet is usually removed, not dried in place.
Fiberglass and blown insulation act like a sponge. When it has been soaked, it can keep dripping onto the ceiling long after the rain ends, which is why a stain keeps growing even in sunshine.
Removing it is also what makes drying possible. Without it, the crew can see the framing and the back of the drywall, take real readings, and put dehumidification where it works. Replacement insulation is a repair step quoted after drying.
The EPA advises drying wet materials within 24 to 48 hours to limit mold, and warm, humid Florida air makes that guideline tighter in practice. It is not a deadline: mold may already have started in that window, and drying afterward does not prove it did not.
Ceiling drywall and attic framing give mold a dark, damp place to start. If the leak is old, the ceiling may already have it, and cutting out wet drywall can reveal it.
Florida licenses mold assessors and mold remediators separately, and the law applies to mold areas above about 10 square feet. If you find more than a small patch, the mold remediation page explains the steps and the separation between testing and removal.
Do not climb onto a wet or damaged roof to look for the hole, and do not stand under a ceiling that is bulging with water. If water is dripping from a light fixture or fan, leave the switch alone and turn the breaker off only if the panel is dry.
The crew checks for bulging drywall that could drop water and for wet fixtures. A sagging section may be poked open on purpose to drain it into a bucket, which is safer than letting it fail on its own.
If the roof can be reached safely, a temporary tarp goes over the damaged area. If it cannot, such as when the roof is wet or the weather is still moving through, the crew will tell you rather than climb it.
Photos and moisture readings are taken before anything is cut out. Ceiling stains, attic insulation and the walls below are recorded so you have a file for your insurer, who decides coverage.
Wet insulation and soaked ceiling drywall are usually removed because they hold water. Cutting a clean line beyond the wet edge lets air reach the framing.
Air movers and dehumidifiers run until readings match dry materials elsewhere in the house. The crew returns to re-check; repairs and repainting come only after the framing is dry.
A slow drip around flashing or a plumbing vent can wet the same patch of insulation for weeks. It often means a smaller opening up front and a larger moisture problem later, so the question is how long it has been going on.
Wind can lift a section of shingles or move a tile in an afternoon, and the rain that follows can wet a large area quickly. The crew's priority is the cover first, then the water.
Underlayment and flashing can fail while the surface looks fine. A thermal camera and moisture meter inside the house can find where the water traveled, which a roofer can use when looking for the entry point.
Roof leak cost splits into the cover, the interior cleanup and the repairs afterward. Roof replacement is outside this page and is not priced here.
| Job | Typical range | What it includes |
|---|---|---|
| Temporary roof tarp, small roof (up to about 1,500 sq ft) | $200–$1,300 | Depends on size, pitch, access and how many sections need coverage |
| Whole-job water damage restoration, typical Florida home | about $1,200–$5,500 | Florida examples; a leak confined to one ceiling will often land below this |
| Ceiling water damage repair, one section | $400–$2,800 | Low-confidence range; depends on texture, paint and framing |
| Water-damaged drywall section replaced | $600–$1,550 | After drying; paint is extra |
| Drywall hang and finish, per sq ft | $1.50–$6.00 | Paint extra |
| Air mover, per unit per day | $25–$50 | Equipment cost is part of the drying line |

Single-storey block-and-stucco houses with tile or shingle roofs are the common pattern across Port St. Lucie, from the 1960s and 70s General Development lots near River Park to the growth-era homes along Becker Road and in Southbend Lakes. With one storey, a roof leak has no floor above to catch it. The water goes into the attic and then down into the ceiling below.
The rainy season here runs roughly May to October, with about two thirds of the year's rain in those months by the NOAA 1991-2020 normals for Fort Pierce, and September is the wettest month at roughly 7.8 inches. That is when slow leaks are most visible. Atlantic hurricane season runs 1 June to 30 November, with its peak around 10 September.
Roof repair needs a permit in many cases, and the permit office depends on where you live: the City of Port St. Lucie Building Department, St. Lucie County outside the city, or Martin County's building permits office in Stuart for addresses there. Ask your roofer who pulls the permit, and keep the roofer's licence number and permit record along with your insurance paperwork.

After a storm pushes water into your home, make it safe first: stay out of standing water near outlets, shut off the main water valve if a pipe is involved, and photograph everything before moving it.
It is safer not to. Wet tile and shingles are slippery, and a fall is a far bigger problem than a stain. Cover the opening from the inside as best you can, move belongings, and call so a crew can assess it.
Wet ceiling drywall that is sagging, stained through or soaked is often removed so the framing can dry. The crew explains what comes out and why before cutting, and you approve it.
It depends on the cause and your policy. Storm damage is often handled differently from wear and tear, and flood is separate. Your insurer decides, so call early and give them the photos and readings the crew records.
Not until the ceiling and the attic framing are dry. Paint over a damp ceiling traps moisture, and stain-blocking primer does not remove the water source or any mold that has started.
Usually several days, depending on how much insulation and drywall were wet. The crew re-checks readings rather than working to a calendar, and tells you when the framing reaches dry readings.
Treat the fixture as unsafe. Water in a ceiling light box can reach wiring. Leave the switch alone, turn the breaker off if the panel is dry, and have an electrician check it before reuse.
