Roof Waterproofing in South Florida

What Is Roof Waterproofing?
Roof waterproofing seals a roof's surface, seams, and flashing so water cannot get in. In South Florida, it matters most on flat and low-slope roofs, where heavy rain, intense sun, and hurricane season push water toward every weak spot. A well-waterproofed roof stays watertight longer and protects the structure below it.
At Lionz Roofing, we waterproof flat roof and low-slope systems on homes, condos, and commercial buildings across Fort Lauderdale, Broward, Miami-Dade, and Palm Beach counties. Every project starts with an inspection, so we can recommend the right approach for your roof.

Our Waterproofing Services
Flat Roof Waterproofing
We restore the waterproofing on existing flat and low-slope roofs by resealing seams, repairing flashing, and sealing around penetrations like vents, drains, and HVAC curbs. It works on common membrane systems, including TPO roofing, EPDM roofing, and other flat roofing systems.
Elastomeric Roof Coatings
An elastomeric roof coating is a flexible, liquid-applied layer that forms a seamless waterproof surface over an existing roof. It helps protect the roof from UV damage and can extend the life of a roof that is still sound. The same type of coating is the protective top layer on SPF roofing systems.
Why South Florida Roofs Need Waterproofing
Heavy Rainfall
South Florida's rainy season brings frequent downpours that test every seam and flashing detail on a roof.
Intense UV
Year-round sun breaks down roofing surfaces over time, leaving membranes brittle and prone to cracking.
Constant Humidity
Moist air keeps roofing materials damp for long stretches and speeds up wear on seams and sealants.
Flat & Low-Slope Roofs
Water drains slowly on flat roofs, so ponding water sits on the surface and finds any weak spot.
Hurricane Season
Wind-driven rain pushes water sideways into seams, roof edges, and flashing.
Signs Your Roof Needs Waterproofing
Ponding Water
Standing water that is still on the roof 48 hours after a storm.
Leaks or Drips
Water coming through the ceiling, especially after heavy rain.
Ceiling or Wall Stains
Brown rings, peeling paint, or damp spots on upper floors.
Cracked or Blistered Membrane
Cracks, bubbles, or open seams in the roof surface.

Waterproofing vs. Roof Replacement
Waterproofing extends the life of a roof that is still sound. It is not a fix for a roof that has failed underneath.
When Waterproofing Is Enough
- The roof deck is dry and structurally sound
- Damage is limited to seams, flashing, or small areas
- The membrane still has useful life left
When Replacement Is the Better Option
- Moisture is trapped under the membrane or in the insulation
- The deck is soft, rotted, or damaged
- Leaks are widespread or keep coming back
- The roof has reached the end of its service life
We tell you which applies after inspecting your roof. If a full roof replacement is the better investment, we explain why.

Frequently Asked Questions
Have questions about our roofing services? Find answers to the most common questions below, or reach out to our team directly.
It depends on the system, the condition of the roof underneath, and how well it is maintained. Elastomeric coatings are designed to be recoated over time instead of torn off. After inspecting your roof, we explain what to expect for your specific system.
Often, yes. If the deck is dry and structurally sound and the damage is limited to seams, flashing, or small areas, waterproofing can extend the roof's life. If there is trapped moisture, deck damage, or widespread failure, a replacement is the better option.
It depends on the roof. Membrane systems like TPO, EPDM, and SPF are strong choices for a new flat roof, while membrane restoration or an elastomeric coating can extend the life of an existing roof that is still sound. We recommend the right option after an inspection.
