Flat Roof Repair in Miami — TPO & Modified Bitumen
Flat roofs are common on Miami homes, additions, and garages — and they have very different failure modes than pitched roofs. Top Florida Roofing's flat roof specialists repair TPO membrane, EPDM rubber, modified bitumen, and built-up systems across Miami-Dade. Blistering, seam failures, drain blockages, and ponding water — we find and fix the real cause. Free drone inspection.
Flat roof leaks rarely originate directly above the interior stain — water travels horizontally under the membrane. We use drone inspection combined with infrared moisture scanning to locate wet insulation precisely, without destructive probing.
A properly executed repair on a sound membrane absolutely lasts. If the membrane itself is aged (most TPO and EPDM systems have a 15–20 year lifespan), repair costs can exceed 40–50% of replacement cost — at which point replacement pencils out better. We'll give you an honest assessment.
Additions with flat roofs frequently have improper drainage slope (less than 1/4" per foot minimum) and failing wall flashings. Both are structural issues, not just material failures. We address slope and flashing simultaneously.
We do emergency tarping in any weather. Permanent membrane repairs require dry conditions — adhesives and heat welding don't perform correctly on wet substrates. We tarp same-day and schedule the permanent repair as soon as conditions allow.
TPO is a thermoplastic — seams are heat-welded with a commercial hot-air welder. EPDM is a thermoset rubber — seams are bonded with EPDM splice adhesive. Using the wrong repair method (e.g., caulk) on either system results in failure within one season.
