Low-Slope Waterproofing Membranes & Applications

Self-Adhered SBS Mod-Bit

Polyglass multi-ply self-adhering modified bitumen system featuring an elastomeric base sheet and white reflective mineral granule cap sheet. No open torches required.

Ideal for: Residential Patios & Balconies

Heat-Welded TPO Single-Ply

60-mil white thermoplastic polyolefin membrane with hot-air robotic welded seams that become stronger than the membrane itself. 100% resistant to ozone, algae, and UV rays.

Ideal for: Commercial Roofs & Multi-Unit

Elastomeric Liquid Membranes

Reinforced liquid-applied polyurethane and silicone coatings engineered to form seamless waterproof wraps around complex parapets, HVAC curbs, and deck tie-ins.

Ideal for: Rooftop Terraces & Equipment Curbs

Atmospheric Resilience

Engineering Low-Slope Waterproofing for South Florida's Extreme Micro-Climate

Between Atlantic tropical cyclones, afternoon convective cloudbursts dumping 3+ inches of rain per hour, and intense ultraviolet radiation, South Florida is America's most demanding roofing proving ground.

Zero Ponding Tolerance

Tapered ISO insulation boards engineered with 1/4" per foot slope directing water to drains.

Multi-Ply System Redundancy

Base sheet, elastomeric interply, and granule cap sheet providing triple-layer protection.

Heat-Welded Robotic Seams

Hot-air fused TPO seams that are physically stronger than the membrane itself.

Parapet Term Bar Wrap

Heavy-duty aluminum termination bars with continuous polyurethane counter-flashing.

Florida Building Code 8th Edition (2023)

High-Velocity Hurricane Zone (HVHZ) Standards for Low-Slope Waterproofing

Broward and Miami-Dade counties comprise Florida's High-Velocity Hurricane Zone (HVHZ)—a special code designation demanding rigorous laboratory wind-tunnel and missile-impact testing for all roofing assemblies.

TAS 100(A) Wind-Driven Rain Test PASSED (110 MPH Rain)

Simulates severe tropical storm conditions to guarantee zero water penetration past underlayment seams.

TAS 125 Wind Uplift Resistance 175+ MPH Upward Draft

Verifies that structural fasteners, clips, and adhesive matrix will not delaminate from the roof deck under Category 5 hurricane wind suction.

Form OIR-B1-1802 Insurance Credit Guarantee

Uniform Mitigation Verification

Upon project completion, our certified inspector documents deck nail spacing, underlayment type, and roof geometry to deliver an executed Wind Mitigation Inspection package directly to your insurance agent.

Quality Assurance

Common Low-Slope Waterproofing Failure Modes (And How We Eliminate Them)

Substandard roofing jobs in South Florida frequently leak within 5 to 7 years due to thermal fatigue, improper nail placement, and cut corners on perimeter flashings.

FAILURE MODE 01

Reverse Slope & Stagnant Ponds

Inadequate slope leaves standing water ponds that degrade asphalt and breed mosquitoes.

Smart Solution: Engineered tapered ISO insulation crickets.
FAILURE MODE 02

Improper Tile-to-Flat Tie-Ins

Flat membranes terminated too low on adjacent tile slopes allowing windward water entry.

Smart Solution: 24" under-tile membrane extension with metal transition flashing.
FAILURE MODE 03

Unsealed Parapet Counter-Flashings

Water entering behind parapet wall termination bars causing ceiling leaks inside building.

Smart Solution: Mechanical term bar fastening + continuous elastomeric counter-flashing.

Transparent Pricing & Cost Factors for Low-Slope Waterproofing

We reject hidden fees and surprise change orders. Our itemized estimates break down structural timber, underlayment square yardage, fasteners, and permit fees down to the exact dollar.

Tapered Insulation Requirements: Thickness of ISO rigid foam board required to correct positive drainage slopes.
Deck Type (Wood vs Concrete): Mechanically attached base sheet with tin tags vs hot asphalt / self-adhered concrete primer.
HVAC Unit Curbs & Scuppers: Number of rooftop air conditioning stands, duct pass-throughs, and scupper conductor heads.
Membrane Type Selected: Multi-ply SBS modified bitumen vs 60-mil reflective white TPO single-ply.
Typical Investment Range
$6.50 - $11.50 / sq. ft.
