Water is dripping from the porch ceiling again, or there’s a brown ring spreading across the ceiling of the room you added on. You’ve been up the ladder and the flat roof looks fine. Somebody may have already smeared a coat of roofing tar over it, and the leak came back after the next storm.
That’s the most frustrating part of flat roof repair in Clermont: the spot where the water shows up inside is often not where it’s getting in. A good repair starts with finding the real entry point. APC Roofing is GAF Certified, licensed in Florida (CCC1337030) and insured, and your leak inspection is free.
Where flat roof leaks usually start
The open middle of a membrane rarely fails on its own. Leaks gather at the places where something interrupts it.
Seams. Where two sheets overlap, the joint is either heat-welded (TPO) or sealed with primer and tape (EPDM). An open lap, even a short one, lets water travel under the membrane.
The tie-in to the main roof. Where a porch or addition meets a steeper shingle or tile roof, the membrane should run up under the main roof covering. If it was laid on top instead, water from the upper roof runs right in behind it. A wet stripe on the porch ceiling next to the house usually points here.
Edges. Wind lifts the perimeter of a low roof first. Loose edge metal or backed-out fasteners give the wind a place to grab, and once the edge lifts, rain follows.
Pipes, AC lines and brackets. Each opening is sealed with a rubber boot or a small pocket of sealant. Both crack and shrink with time and sun.
Punctures. A dropped screw, a technician’s tool or a branch from a summer storm can make a hole you’d never spot from a ladder.
Ponding. Water still standing two days after rain usually means a clogged drain, scupper or gutter, or a deck that has sagged. It speeds up wear right where it sits.
How a flat roof leak gets traced
Water that gets under a membrane can run sideways through the insulation before it finds a way into the room. So the inspection doesn’t stop at the stain.
Your roofer starts with the drainage: drains, scuppers, gutters and low spots. Then every seam gets probed along its full length, and the edges, boots and tie-in get checked. On a roof that’s actively leaking, a moisture meter and sometimes a small core sample show how far the water has spread inside the roof. You’ll get photos of what turned up and a written summary of the repair.
What the repair looks like
Most flat roof leaks trace back to one small area, and a proper patch fixes them. On a TPO roof, a matching piece is heat-welded over the damage and the edges are probed to make sure it’s sealed. On EPDM, the area is cleaned and primed, and a cover patch with rounded corners is taped down so it won’t peel.
Other repairs are about the detail around the leak:
- A failed pipe boot gets replaced with a new molded boot and clamp.
- A backwards tie-in gets rebuilt so the main roof laps over the membrane, not the other way around.
- Loose edge metal gets refastened or replaced before the wind can peel the sheet.
- A clogged drain or scupper gets cleared, and a deck that holds water may need tapered insulation or an added drain.
Caulk and tar smeared over a seam aren’t a repair. They crack in a season or two of Florida sun, and the leak returns.
When repair isn’t the right answer
Sometimes the inspection shows more than one bad spot. If seams are failing across the whole roof, the membrane has gone brittle or large areas of insulation are soaked, patching becomes money spent on a roof that’s done. In that case, you’ll hear it plainly, with the photos and moisture readings to back it up, and the decision stays yours. Our Clermont flat roofing page covers replacement options, including TPO roofing and EPDM roofing.
If the leak turns out to be coming from the shingle or tile roof above, not the flat section, the same inspection catches it. APC Roofing works on both, so you don’t need a second company to track it down. See our Clermont roof leak repair page for leaks on the main roof.
Storm damage and insurance
If a storm damaged your flat roof, you file your own claim with your insurance company and pay your own deductible. APC Roofing documents the damage with photos, gives you a written estimate and works with your adjuster so the damage is clearly accounted for.
Weather and timing
Membrane repairs need a dry surface. In a Clermont summer, that often means a morning repair before the afternoon storms build. A small patch fits a short dry window. Any section that gets opened is sealed watertight before the crew leaves.
How it works
- Book your free inspection. Call 407-270-1129 or request a free estimate online, and tell us what you’re seeing inside.
- Get a clear, honest assessment and estimate. Photos, the cause of the leak and a written estimate for the fix.
- Your roof gets fixed and the site gets cleaned up. The repair gets done right, and the crew cleans up before leaving.
A flat roof leak that’s left alone keeps feeding water into the insulation and decking. Fixed early, it’s usually a patch. Left through a rainy season, it can mean replacing wet insulation and soft deck along with the membrane.
Flat roof repair questions
Why does my flat roof leak only in heavy rain?
Heavy, wind-driven rain pushes water into openings a light shower never reaches, like a lifted edge, an open seam or a backwards tie-in. Water also builds up faster than a partly clogged drain can handle.
Can you just put tar on it?
Tar or caulk can slow a drip for a short while, but it isn’t a lasting repair. The opening needs a proper patch or a rebuilt detail.
Will my ceiling need repair too?
Possibly. Once the roof leak is fixed and the area dries out, you’ll know how much of the ceiling was affected. Wet insulation in the roof itself needs to be replaced, not left to dry.
How do I know if my flat roof needs replacing instead?
Several failing seams, brittle or shrinking membrane, and wet insulation across a large area all point to replacement. The inspection photos and moisture readings will show which side of that line you’re on.
