The power of hot asphalt for commercial roofs

At International Roofing INC, we specialize in hot asphalt roofing systems (Built-Up Roofing - BUR). We use Type IV hot asphalt because it provides an exceptionally robust, seamless multilayer membrane ideal for commercial applications.

Hot asphalt delivers proven durability with a thick protective layer resistant to weather and traffic. It creates an unmatched chemical and physical bond between membrane layers and the roof substrate, forming a monolithic waterproofing barrier that minimizes failure points.

Why we rely on Type IV hot asphalt

A built-up roofing system engineered for maximum protection, adhesion, and waterproofing.

Proven durability

Creates an exceptionally thick membrane that resists UV exposure, ponding water, and heavy foot traffic.

Superior adhesion

Hot asphalt delivers a chemical and physical bond between each ply and the deck for monolithic performance.

Waterproof barrier

Minimizes failure points by eliminating seams and sealing every fastener penetration.

Superior Technology

Premium System

We carefully select top-quality components for every layer of your new roof.

Base layers & reinforcement

We start with dimensional stability so the rest of the system can perform for decades.

  • GAFGLAS #75 Base Sheet 3 SQ
    • Premium fiberglass base sheet engineered for built-up roofing.
    • Factory-coated to prevent asphalt bleed-through and support multi-ply systems.
  • GAF RUBEROID 20 Smooth 1.5 SQ
    • SBS-modified bitumen base that stays flexible in low temperatures.
    • Ideal as the first ply for new systems or recover projects.
Asphalt & adhesion

Type IV hot asphalt and professional mop tools deliver the seamless bond we promise.

  • Venezuelan Asphalt Type IV
    • High-performance asphalt formulated for hot-mop applications.
    • Fuses every membrane layer to create a continuous waterproof surface.
  • Mop Yarn White 2.5# Hanks & Staple set
    • Professional-grade cotton yarn that spreads hot asphalt evenly.
    • Staples keep each mop secured for safe, consistent application.
UV & cool-roof protection

Top coats that lock performance in and reflect heat away from the building.

  • GAFGLAS Mineral Surfaced Cap
    • Mineral-finished cap sheet that protects the membrane from UV damage.
    • Adds impact resistance and keeps the system stable under Florida heat.
  • 3M White Granules – 50 lbs
    • Adhered with exterior-grade adhesive to lock the top layer in place.
    • Provide cool-roof properties that reflect solar energy and lower cooling costs.
Installation accessories

Fastening hardware that keeps every edge tight and code-compliant.

  • Tin Caps 1 5/8" Galvanized
    • Galvanized tin caps distribute fastener pressure across the base sheet.
    • Add stability to insulation boards and prevent pull-through.
  • MDCoil 1-1/4" Roof Nails
    • Roofing nails engineered for secure fastening in coastal climates.
    • Corrosion-resistant finish keeps the attachment reliable over time.
  • Drip Edge 3" x 3" x 10' Galv
    • Directs water away from the facade and into gutters.
    • Galvanized steel resists rust and protects perimeter edges.
Repair & emergency solutions

Fast-response materials we keep in every truck for on-the-spot fixes.

  • KARNAK 155 AMPHIBIKOTE
    • Cold-applied asphalt cement that adheres to wet or dry surfaces.
    • Ideal for emergency leak mitigation before full repairs.
  • Karnak Membrane Black 4" x 150"
    • Cotton membrane saturated with asphalt for reinforcing repairs.
    • Perfect for flashings, seams, and critical roof transitions.
