Summer feeds every leak
Tampa averages 49.48 inches of rain a year, and about 30 inches of it falls from June through September, according to the National Weather Service.
Hot roofs open up
The EPA says regular roofs can reach 150 to 185 degrees in peak summer sun. That heat dries out sealants and opens small gaps at seams and flashing.

A leak on a flat roof almost never comes straight down. Water slips in at one weak spot. Then it runs along the metal deck, soaks into the insulation, or follows a pipe or beam. It drips out wherever it finds a low point. On a big warehouse or office roof, that can be 10, 20 or even 50 feet from where the water got in.
That is why patching the spot right above the stain so often fails. The real fix starts with finding the entry point.
Ceiling tiles that stain after storms
And dry out between them. The leak is real, even if it comes and goes.
A drip that starts an hour into a hard rain
The water had to travel or build up before it came through.
Water near the rooftop AC unit
Curbs and pipe holes around units are a top leak point.
Leaks along an outside wall
Often the flashing where the roof meets the wall or parapet.
Rust stains on the deck or joists
Above the ceiling. Water has been getting in for a while.
A musty smell or new mold spots
In one area of the building.
Wet insulation or sagging tiles
The roof may be holding more water than you can see.
Tampa gets most of its rain in a short window. The National Weather Service puts the yearly average at 49.48 inches, with about 30 inches falling from June through September. Those are the months of the daily afternoon storm. Rain comes fast and hard, often with wind behind it.
A flat roof has to move all that water to its drains in minutes. If a drain is partly blocked by leaves or debris, the water rises. Once it gets deep enough, it can reach the top of a flashing or the edge of a seam that would stay dry in a light rain. Wind pushes water sideways under metal edges and into gaps around rooftop units.
Heat is the other half of the story. The EPA says regular roofs can reach 150 to 185 degrees in peak summer sun. Every day the roof heats up and cools down. Over time that wears out sealants, dries out caulk around pipes, and loosens seams. Then the afternoon storm finds the gap.
The inspector checks the same short list on almost every roof:
A leak that drips only in hard rain, in one spot, away from power and equipment, is usually a repair job. It still needs fixing soon. Every rain adds water to the insulation.
Call right away if any of these are true:
Water near electrical panels, lights or equipment
Shut off what you safely can and keep people clear.
A ceiling that sags or bulges
Water is pooling above it.
A roof that feels soft or bouncy
The deck or insulation may be soaked or damaged.
Leaks in many spots at once
The roof may be near the end of its life, or storm damage may have opened it up.
Your local crew starts inside, at the stain, and notes where it sits under the roof. On the roof, they check the drains, seams and flashing in that area first. They look for open seams, cracked sealant and holes.
For a hard-to-find leak or a wide wet area, an infrared scan can show where the insulation is holding water. Published guides put it at about 5 to 12 cents per square foot. The scan also tells you how much of the roof is wet, which matters for repair versus replacement.
Most leaks are fixed with a seam repair, new flashing around a curb or pipe, or a drain repair. Wet insulation under the leak may need to be cut out and replaced so it does not keep feeding moisture into the roof.
Typical ranges from published cost guides are in the table on this page. Most flat roof leak repairs land around $300 to $1,100. Seam repairs run about $200 to $1,000, and flashing repairs about $200 to $750. Leaks that have soaked a large area of insulation cost more. Your written estimate gives the real number for your roof.
Catch the water
With buckets or a tarp on the floor, and move stock, records and equipment.
Take dated photos
Of every stain and drip. Note the date, time and how hard it was raining.
Write down when it leaks
Every rain, only hard rain, or only with wind from one side. That pattern helps the inspector.
Find your roof records
Install date, roof type, any warranty and past repairs.
Keep staff off the roof
During storms and away from wet or soft areas.

A small opening can stay dry in light rain. In a hard Tampa downpour, water backs up at drains, gets pushed sideways by wind, or rises high enough to reach a flashing gap. That is why many leaks show up only in summer storms.
Often not. On a flat roof, water gets in at one spot, then runs along the deck or through the insulation before it drips. The inspector starts at the stain and works back to the seams, curbs and drains nearby.
It can be either. A clogged condensate line can drip inside on dry days, which points to the unit. A drip that shows up only during rain points to the roof, often the flashing around the unit's curb. The inspector checks both.
It is risky. Most of Tampa's rain falls from June through September, so a leak in summer gets fed almost every day. Wet insulation under a flat roof can turn a small repair into a large one.
Tarps do not hold well on a flat roof and can trap water. Put a bucket or tarp inside, move stock and equipment, and call for a roof check. Keep staff off the roof during storms.
