Commercial Flat Roof Repair

Commercial Flat Roof Repair in Miami

Flat roof repair in Miami is usually urgent. A leak over an office, a store or an apartment unit means damaged ceilings, wet inventory and unhappy tenants. R&D Construction & Roofing, LLC repairs commercial flat and low-slope roofs across Miami-Dade, Broward, Palm Beach, Monroe and the Tampa Bay area.

We are a family-owned, licensed and insured roofing contractor and general contractor. Our goal on a repair call is simple: find where the water is actually getting in, fix it properly, and tell you honestly whether the roof has more life left or is nearing replacement.

What Flat Roof Repair Covers

Most commercial roof leaks start at a small number of weak points. Common repairs include:

Membrane damage: Punctures, splits, blisters and worn areas on TPO, PVC, modified bitumen and built-up roofs.
Seam failures: Seams that have opened up from age, poor original welding or wind stress.
Flashing repairs: Walls, parapets, curbs and roof edges where flashing has pulled loose or cracked.
Penetrations: Pipes, vents, HVAC stands and conduit that were not sealed correctly or have shifted.
Drainage problems: Clogged drains and scuppers, or low spots where water sits for days.
Storm damage: Lifted edges, torn membrane and debris damage after high winds.

The water stain inside is often nowhere near the entry point on the roof. Water can travel along the deck or insulation before it shows up, which is why careful inspection matters more than patching the first thing that looks wrong.

When a Repair Makes Sense

A repair is usually the right call when the damage is limited and the rest of the roof is in reasonable condition. If leaks keep appearing in different places, the insulation is saturated or the membrane is brittle across the roof, repeated patching tends to cost more over time. In those cases we may suggest a silicone coating system to restore the surface, or a full commercial roof replacement.

Our Repair Process

Call and triage: Tell us what you are seeing. If water is actively coming in, we work to get the roof temporarily protected as quickly as we can.
Inspection: We walk the roof, check seams, flashings, penetrations and drains, and trace the likely path of the water.
Findings: You get a plain explanation of the cause, photos and a written repair scope with pricing.
Repair: We use materials compatible with your existing roof system, whether that means welding new membrane, re-flashing a curb or rebuilding a drain detail.
Follow-up: We check the repair and note any other areas that should be watched or scheduled for later.

Why Flat Roofs Leak in Florida

Florida is hard on low-slope roofs. A few local factors come up again and again:

Heavy rain and ponding: Afternoon storms dump a lot of water quickly. If drains are slow or the roof has low spots, water sits and finds any weakness.
Sun and heat: Constant UV exposure and heat cycling wear down membranes, sealants and coatings over time.
Wind: Tropical storms and hurricanes put uplift pressure on roof edges and corners, loosening flashing and opening seams.
Rooftop equipment: HVAC units, service traffic and new penetrations are frequent leak sources.

Code matters too. Miami-Dade and Broward are in the High-Velocity Hurricane Zone under the Florida Building Code, and larger repairs may require a permit and materials with the proper product approvals. If yours does, we handle the permitting.

Flat Roof Repair FAQ

How fast can you respond to a roof leak?

Call us as soon as you notice it. Response time depends on weather and demand, especially after a storm, but active leaks are treated as a priority and we work to protect the roof as quickly as possible.

Can you repair any type of flat roof?

We repair common commercial systems including TPO, PVC, modified bitumen, built-up roofs and coated roofs. Repairs are made with compatible materials so they bond properly.

Should I repair or replace my flat roof?

If the damage is limited and the rest of the roof is sound, repair is usually the better value. If leaks are widespread or the insulation is wet, replacement or a restoration coating may be more cost-effective. We will give you an honest assessment.

How can I prevent future leaks?

Regular inspections, clear drains and quick attention to small problems go a long way. Our roof maintenance program is built for that. You can also learn more about our roof repair services.
