A flat roof rarely leaks where the stain is. Water gets in at a flashing, a seam or a drain, travels along the deck or through the insulation, and drips wherever it finds a way down. Here's how to trace it, how each roof type is repaired, and when a patch, a coating or a new roof is the right call.

Quick answer

Most flat roof leaks start at flashings, seams, drains and penetrations, and the water can travel before it shows inside. A typical repair costs $300–$1,100. If the membrane is attached and the insulation mostly dry, a coating restoration runs about $1–$4 per sq ft; replacement runs $3–$11 per sq ft plus $1–$2 tear-off. Water still standing after 48 hours is ponding. Diagnose your leak or compare your options.

Who's writing: ArmorThane makes polyurea coatings and spray foam in Springfield, Missouri, and trains the applicators who spray them on flat roofs. We don't make EPDM, TPO, PVC or silicone, so this guide starts with the repair and gets to coatings only when a roof qualifies.

How to find a flat roof leak

WATERPROOF! Magazine calls flashings and seams "the weak spots in any roof design," with drains and penetrations close behind. Open field membrane is the least likely source, even when the stain is right under it. Work through the roof in this order before anyone cuts anything.

  1. Read the leak from inside

    Note when it drips: every rain, only long rains or only wind-driven rain. That timing narrows the cause as much as the stain's location.

  2. Clear the drains and scuppers

    A clogged drain holds water over small weaknesses. Clear it before looking for holes; drain repairs run $70–$500 (Fixr, 2026).

  3. Walk the perimeter

    Look where the roof meets walls, parapets and edge metal: base flashing pulling loose, open coping joints, cracked counterflashing, and on EPDM, a sheet "tenting" away from the wall as it shrinks.

  4. Check every penetration upslope of the stain

    Curbs, vents, pipes, skylights and pitch pans. Flashings should lap over the membrane on the downhill side, and pitch-pan sealant should crown above the lip so it sheds water.

  5. Probe the seams

    Check single-ply seams with a probe or pick for open laps and fishmouths. On mod bit and built-up roofs, look for splits, blisters and laps with no bitumen squeezed out at the edge.

  6. Water test one area at a time

    Still stuck? Wet one small area at a time, working up from downslope of the suspect spot, while someone watches inside.

How the pros find leaks and wet insulation

Instruments help on big roofs, but none replaces a look at the flashings. Angi puts an inspection at $75–$600 depending on method.

Flat roof leak triage

Pick your roof type and what you're seeing. The tool suggests where to look first, the likely cause and the usual repair, based on NRCA, InterNACHI and manufacturers' repair guidance.

Leak triage

Where is my flat roof leaking from?

A starting point for you or your roofer, not a substitute for a roof inspection.

Also true?
Flashing repair
Likely repair
Wall, parapet and edge flashing
Look here first
Shrinkage pulling the sheet off the wall, or loose flashing
Most likely cause

Flashing repair (EPDM). Reseal or replace the flashing where the roof meets the wall, and check the coping and counterflashing above it. EPDM seams often develop defects within the first three years, and shrinkage pulls the sheet away from walls (“tenting”). Weathered EPDM must be cleaned and primed before pressure-sensitive patches will stick. A sound EPDM roof needs no coating. HomeGuide suggests weighing replacement for roofs 10–15 years old that need extensive repairs; one leak isn’t that, several are.

By roof type

Flat roof repairs by membrane type

A patch has to match the roof: EPDM takes primer and pressure-sensitive tape, TPO and PVC take heat welds, mod bit takes compatible bitumen. The wrong material may peel off or attack the membrane.

Rubber sheet

EPDM

Where it leaks: seams (InterNACHI says defects often show within three years), flashings, and walls where a shrinking sheet tents away. Oils and solvents damage it.

How it's fixed: clean and prime the rubber, apply pressure-sensitive patches or tape, and seal edges with lap sealant. Sound EPDM needs no coating; our rubber roof coating guide covers when one makes sense.

Welded single-ply

TPO

Where it leaks: hand-welded seams, flashings and punctures; older TPO near hot equipment can degrade.

How it's fixed: probe seams for at least a 1.5 in weld. Weathered TPO must be scrubbed and cleaned so new welds take, then failed spots are rewelded or overlaid. For coating over it, see TPO roof waterproofing.

Welded single-ply

PVC

Where it leaks: seams, and wherever the sheet has turned brittle. An NRCA technical paper blames most long-term PVC failures on embrittlement from heat and UV.

How it's fixed: condition and reweld seams. Keep PVC away from asphalt and polystyrene. Ask whether very brittle PVC is worth patching at all.

Asphalt, torched or cold

Modified bitumen

Where it leaks: laps, splits at inside corners, flashings and blisters; granule loss exposes the asphalt.

How it's fixed: reseal or patch laps with compatible material; good laps show 1/4–1/2 in of bitumen run-out. APP mod bit isn't compatible with asphalt cement, and pitch pans aren't recommended on it.

Tar and gravel

Built-up (BUR)

Where it leaks: splits over deck joints, alligatored (craze-cracked) asphalt, flashings and blisters between plies.

How it's fixed: seal cracks and bare spots. Small intact blisters can be left; 3–5 ft blisters need repair, and widespread large ones mean the roof is near its end (InterNACHI). Gravel has to come off before GAF's silicone goes on.

Sprayed foam

Spray foam (SPF)

Where it leaks: where the coating has worn thin and sunlight has degraded the foam, plus hail dents and punctures.

How it's fixed: SPFA says caulk and coat light damage; scarify 1/2 in, refoam and coat heavy damage. IBHS puts recoating at every 10–20 years. See spray foam roofing.

Panels

Metal

Where it leaks: loose fasteners and worn washers, laps, rust at the laps and penetrations, rarely the panel itself.

How it's fixed: secure or replace fasteners, prime rust, and seal laps and fasteners with fabric-reinforced mastic, the prep coating makers require before a restoration. See metal roof repair.

Standing water

Ponding water on a flat roof

Every flat roof holds a little water after a storm; the problem is water that stays. NRCA's test is "no ponding water on the roof 48 hours after a rain during conditions conducive to drying," and the Asphalt Roofing Manufacturers Association uses the same 48 hours.

The International Building Code requires membrane roofs (except coal-tar built-up) to slope at least 1/4 inch per foot, a 2% slope. Reroofing is exempt if the roof keeps positive drainage, which is why many older roofs are flatter than a new one would be.

What ponding does

  • Adds weight that deflects the deck, so it holds more water
  • Speeds "deterioration of the membrane surface" (ARMA)
  • Freezes into ice that scrubs the membrane
  • Grows algae and vegetation
  • Soaks seams and wets insulation

How it's fixed

  • Clear drains; add or move drains at low spots
  • Add crickets and saddles behind curbs
  • Build slope with tapered insulation
  • Add overflow drains where code requires
  • If you coat, pick a chemistry made for standing water

Coatings differ here. GAF says silicone is "great for applications where you need ponding water resistance," as does our silicone roof coating guide, while our roof coating guide recommends acrylic only where drainage is reliable. A coating doesn't remove the water or its weight, though. HomeGuide lists pooling and sagging repairs at $800–$2,500; Fixr lists ponding fixes at $70–$750.

The big decision

Repair, restore or replace?

Three questions decide it: how wet is the insulation, is the membrane still attached, and how old is it?

Repair

Fix the leak

  • One or a few leaks at flashings, seams or drains
  • Roof is well inside its service life
  • Insulation is dry beyond the leak area
  • Typical cost: $300–$1,100 (HomeGuide)
Restore

Coat the whole roof

  • Membrane is aging but still attached and "clean, dry and tight" (GAF)
  • Wet areas are small and get cut out and replaced first
  • Coating passes an adhesion test
  • Typical cost: $1–$4 per sq ft (HomeGuide)
Replace

Tear off and reroof

  • Insulation is widely wet, or the roof is brittle, split or loose
  • Repairs would cost more than half of a new roof (Angi)
  • There are already two roof coverings
  • Typical cost: $3–$11 per sq ft plus $1–$2 tear-off

The wet insulation question

Wet insulation is what usually rules out a coating: "Wet insulation left beneath a new coating will cause blistering, failed adhesion, and continued leaks," as one coating contractor puts it. Many treat about 25% wet as the limit for a restoration, a rule of thumb rather than a standard. GAF's silicone spec requires a moisture survey and says to "remove and replace any wet areas."

Age matters too. HomeGuide puts flat roof life at 15–25 years and suggests weighing replacement for roofs 10–15 years old that need extensive repairs. Angi's rule: when a repair costs more than half of a replacement, replace.

Code limits on roofing over a roofThe International Building Code's reroofing section (2018 edition) doesn't allow a new roof covering over an existing one where the roof is "water soaked or has deteriorated to the point that the existing roof or roof covering is not adequate as a base," or where there are already "two or more applications of any type of roof covering." Your building department has the final word.

Restore. At 12 years the roof is at the age where HomeGuide suggests looking past spot repairs, and with 5% wet it may still be dry enough to coat. At the midpoints, restoring costs about 46% of replacing. Restoration here means replacing about 100 sq ft of wet or damaged roof and coating all 2,000 sq ft with silicone ($1.50–$4.50 per sq ft). Coating warranties usually come in 10-, 15- or 20-year terms tied to thickness; a new modified bitumen roof lasts about 10–20 years (HomeGuide).

Published ranges, not a quote. Access, penetrations, local labor and what's under the membrane move real prices.

Restoration

How a coating restoration works

A restoration isn't paint. It's a fluid-applied membrane built to a specified thickness over a roof that has been surveyed, repaired and cleaned. Skip the prep and it peels, blisters over wet insulation, or leaks at the same flashings. These steps follow manufacturers' published specifications.

  1. Moisture survey

    An infrared or impedance scan confirmed with cores. GAF's silicone spec makes it mandatory.

  2. Cut out wet areas

    Replace wet insulation and membrane so the roof is "clean, dry and tight."

  3. Repair and clean

    Fix seams, blisters and flashings, then power wash. On metal, secure fasteners and prime rust.

  4. Test adhesion

    A test patch shows whether the coating bonds; GAF says a primer can help where it fails, and requires the test on smooth asphalt roofs.

  5. Reinforce the details

    Seams, drains, penetrations and fasteners get extra coating and fabric first.

  6. Coat to thickness

    The specified gallons per square earn the warranty term, so ask how many gallons will go on.

Warranty termGallons per 100 sq ftDry film
10 years1.7527 mils
15 years2.2535 mils
20 years2.5039 mils
GAF High Solids Silicone Quick Spec over asphaltic roofs; other makers publish their own tiers. GAF says silicone can be recoated when the warranty ends, and calls for 40°F and rising with no rain, dew or fog for 8 hours.

Which coating?

Silicone handles ponding best, but future recoats generally have to be silicone too. Acrylic costs least and suits roofs that drain well. Polyurea and polyurethane hold up better to foot traffic and impact; our polyurea flat roof waterproofing page covers the sprayed system, and the liquid-applied waterproofing membrane guide compares chemistries by standard.

Doing it yourself

DIY fixes and roof safety

Clearing drains, picking up debris and a temporary patch made for your membrane are fine for a careful owner. So is watching the roof: HomeGuide suggests a pro inspection every 3–5 years plus your own yearly checks, and SPFA says to inspect spray foam roofs twice a year and after severe weather.

Leave heat welding TPO and PVC, torching mod bit and cutting out wet insulation to a roofer. A bad weld or a misplaced torch can make the leak worse, and the wrong patch material can peel off or damage the membrane: asphalt products on PVC and petroleum solvents on EPDM are the classic examples.

Working on a roof: OSHA fall protectionOSHA (29 CFR 1926.501) requires fall protection for workers at roof edges 6 ft or more above a lower level: guardrails, nets, personal fall arrest, or on low-slope roofs a warning line at least 6 ft back plus one of those or a safety monitor. Skylights need covers or guards. The rule binds employers, but it's a sensible guide for anyone. Never step on a skylight.
ArmorThane applicators

Seamless polyurea from certified applicators

When a flat roof qualifies for restoration, ArmorThane-certified applicators spray a seamless polyurea membrane over it, after prep and primer, on roofs from concrete and mod bit to metal and aged single-ply. They're trained on site or virtually and certified by ArmorThane, which has made coatings since 1989 and supplies applicators in more than 50 countries.

If your roof only needs a repair, a good applicator will say so. Use the applicator finder to reach one near you, read more on flat roof waterproofing, and join the newsletter for new roofing guides and price updates.

Flat roof repair FAQ

How much does flat roof repair cost?

HomeGuide puts the typical flat roof repair at $300–$1,100, with a $900 national average, or $2.50–$10 per sq ft. A minor leak runs $150–$500 and an extensive one $1,200–$3,000. Fixr's 2026 average is $700, and labor is roughly 70% of the bill.

How do I find a leak in a flat roof?

Clear the drains, then check the perimeter flashings, every penetration upslope of the stain and the seams. Water often travels under the membrane before it drips, so the leak is rarely right above the stain. If you still can't find it, water test one small area at a time, or have an infrared survey done.

Can I fix a flat roof leak myself?

You can clear drains, remove debris and apply a temporary patch made for your membrane. Heat welding TPO or PVC, torching mod bit and cutting out wet insulation are jobs for a roofer, because the wrong material or a bad weld can make the leak worse. Use fall protection near edges.

What is considered ponding water on a flat roof?

Water that is still on the roof 48 hours after rain, in weather good for drying. That is NRCA's test, and the Asphalt Roofing Manufacturers Association uses the same 48-hour definition. The building code requires new membrane roofs to slope at least 1/4 inch per foot to prevent it.

How do you fix ponding water on a flat roof?

Clear clogged drains first. Lasting fixes add slope or drainage: crickets and saddles, tapered insulation, new or relocated drains, and overflow drains where required. HomeGuide lists pooling and sagging repairs at $800–$2,500. A silicone coating resists ponding water, but it doesn't remove the water or its weight, so fix the drainage too.

Should I repair, restore or replace my flat roof?

Repair a few leaks at flashings, seams or drains when the insulation is dry. Restore with a coating when the membrane is aging but attached and mostly dry, after wet areas are replaced. Replace when insulation is widely wet (many contractors use about 25% as the cutoff), the roof is brittle, or repairs cost more than half of a new roof.

Can you put a coating over a leaking flat roof?

Not as a fix by itself. Coating manufacturers require the roof to be clean, dry and tight first. GAF's silicone specification requires a moisture survey and says to remove and replace any wet areas, and adhesion testing shows whether the coating will bond. Wet insulation left under a coating causes blistering, failed adhesion and continued leaks.

How long does a flat roof coating last?

It depends on the coating and its thickness. Warranties usually come in 10-, 15- and 20-year terms; GAF's high-solids silicone over asphalt roofs calls for 27, 35 and 39 dry mils for those terms. HomeGuide says sealing can add 7–10 years to a roof's life, and most coatings can be recoated.

What is the most common cause of flat roof leaks?

Flashings and seams. Roofing inspectors and trade publications consistently name the joints, not the open field, as the weak spots: wall and edge flashings, penetrations, drains and seams. Ponding water makes any of them worse. On EPDM, InterNACHI notes seam defects often appear within the first three years after installation.

How much does it cost to replace a flat roof?

HomeGuide puts flat roof replacement at $3–$11 per sq ft installed, or $4,000–$16,800 with a $10,800 average, plus $1–$2 per sq ft to tear off the old roof. Angi's 2026 average is $7,433. Modified bitumen and built-up roofs sit at the low end; PVC and metal at the high end.

How do you repair an EPDM, TPO or PVC roof?

EPDM is cleaned, primed and patched with pressure-sensitive patches or tape, with lap sealant at the edges. TPO and PVC are heat-welded: weathered membrane has to be scrubbed and cleaned first, and seams need at least a 1.5 inch weld. PVC must be kept away from asphalt, and very brittle PVC may not be worth patching.
