Water that will not drain
Water still standing about two days after rain points to drainage, slope or clogged-outlet problems.

Flat Roof Repair in Miami
A flat roof depends on its membrane, its seams and how fast water drains away. Most repairs start where one of those three has failed.
DOM or a roofing partner will confirm the appropriate scope.

Signs a flat roof needs repair
The right next step depends on what the roof is doing and what an inspection reveals.
Open seams, blisters or cracks
Separated seams, bubbles in the membrane or surface cracking let water reach the insulation below.
Leaks near walls or equipment
Parapet flashing, curbs under AC units and pipe penetrations are frequent leak points on flat roofs.
A CLEAR SCOPE BEFORE A DECISION
What should a flat roof repair estimate explain?
Expect the membrane type, the exact areas and details to be repaired, how seams or flashing will be sealed, whether wet insulation was found and needs replacing, drainage corrections and any permit requirement.
COMPARE FLAT ROOFING SYSTEMSTHE DETAILS THAT CHANGE THE ANSWER
What does a flat roof inspection check?
Membrane, seams, flashing and drainage are reviewed together, because a leak at one point is often caused by water held somewhere else.
Membrane and seams
Surface wear, punctures, blisters and seam adhesion across the field of the roof.
Drains, scuppers and perimeter
Clogged outlets, ponding areas, parapet and edge flashing, and equipment curbs.
KNOW THE MEMBRANE
TPO, modified bitumen and built-up roofs are repaired differently.
TPO is a single-ply thermoplastic membrane with heat-welded seams; repairs usually involve cleaning and welding a matching patch. Modified bitumen comes in rolled sheets that are torched, self-adhered or set in adhesive, and is repaired with compatible sheets and flashing. Built-up roofs use several layers of felt and asphalt with a surfacing, and repairs rebuild those layers locally.
Using an incompatible material can make a repair fail early, so the estimate should name the existing membrane and the repair product. Compare the systems on the flat roofing systems page.
DRAINAGE COMES FIRST
Why ponding water shortens a flat roof's life.
Flat roofs are not truly flat; they need a slight slope toward drains, gutters or scuppers. When water sits for days, it adds weight, speeds up membrane wear and finds any small opening. Clearing outlets, correcting low areas with tapered insulation or adding drainage can be part of a lasting repair.
After Miami's heavy afternoon storms, check that drains and scuppers are flowing. Leaves, debris and roofing granules collect at outlets and can turn a small roof into a shallow pool.
WET INSULATION AND THE BIGGER DECISION
Repair, restore or replace a flat roof.
Water that gets below the membrane can soak the insulation without showing inside right away. Core samples or an infrared moisture survey can show how much of the roof is wet. Small wet areas can be cut out and replaced during a repair; wide areas change the decision.
Where the roof and insulation are still dry and sound, a restoration coating may extend its life. Where they are not, replacement is usually the better investment. For business properties, see commercial roof repair in Miami; for homes with low-slope sections, the same principles apply on a smaller scale. Miami-Dade County's roofing permit resources explain the county process; cities such as Miami, Hialeah or Coral Gables run their own building departments, so the responsible jurisdiction is confirmed by address.
Spot repair
Patches, seam welds and flashing repairs when the rest of the roof is sound.
Restoration
A compatible coating system over a dry, sound roof where it is permitted.
Replacement
A new membrane and insulation when moisture or wear is widespread.

QUESTIONS WORTH ASKING
Flat Roof Repair in Miami: Common Questions
Clear answers make it easier to choose the right next step for your property.
01How long should water stand on a flat roof?
Water that is still present about 48 hours after rain is generally considered ponding and should be evaluated for drainage or slope problems.
02Can a TPO roof be patched?
Yes. TPO is typically repaired by cleaning the area and heat-welding a compatible patch, provided the surrounding membrane is in good condition.
03Should I coat my flat roof?
A coating can help when the roof and insulation below are dry and sound. It does not fix wet insulation or structural drainage problems.
04Do homes in Miami have flat roofs?
Many do, especially on additions, porches and modern designs. Residential low-slope sections use the same membrane principles as commercial roofs.
05Is a flat roof repair estimate free?
Yes. Request a free initial roof inspection and estimate from DOM.
