Core Specialty Materials Capabilities

Flat Roof Installation

Complete low-slope builds utilizing robotic hot-air welded TPO, thick EPDM rubber, or multi-ply modified bitumen systems with positive drainage sloping.

Flat Roof Repair

Precision diagnostics and repairs for hidden punctures, separated field seams, perimeter flashing splits, and water blisters on commercial flat decks.

Flat Roof Replacement

Tearing off saturated, moisture-trapped insulation, repairing structural steel or wood decking, and installing brand-new high-performance single-ply roofs.

Flat Roof Waterproofing

Applying seamless elastomeric liquid rubber and high-solids silicone barriers that permanently seal complex parapet walls, skylight curbs, and HVAC units.

Flat Roof Coating

Restorative bright-white 100% silicone coatings that reflect 85% of solar heat, slash cooling costs, and provide watertight performance over standing ponding water.

Flat Roof Restoration

Reconditioning aging commercial flat roofs at roughly half the cost of full replacement by re-seaming joints and applying fluid-applied protective membranes.

Flat Roof Drainage Installation

Installing wide-mouth internal roof drains, heavy-gauge perimeter scupper boxes, downspout collector heads, and tapered cricket insulation slopes.

Flat Roof Drain Repair

Replacing corroded cast-iron drain clamping rings, clearing blocked leader bowls, and installing leaf strainers to prevent catastrophic water backups.

EPDM Roofing

Time-tested 60-mil synthetic vulcanized black rubber roofing offering superior UV resilience, extreme freeze-thaw elasticity, and puncture resistance.

TPO Roofing

Energy Star certified bright-white thermoplastic polyolefin heat-welded at 1,000°F, creating monolithic seams 3-4x stronger than conventional glued sheets.

PVC Membrane Roofing

Premium thermoplastic roofing engineered for restaurants and industrial facilities, completely impervious to rooftop grease, animal fats, and harsh chemicals.

Modified Bitumen Roofing

Tough multi-ply polymer-modified asphalt sheets installed via heat-welded torch or cold-applied adhesive, built for heavy pedestrian maintenance traffic.

Built-Up Flat Roofing

Traditional multi-ply asphalt and gravel tar roofing systems delivering proven multi-layer redundancy and heavy impact defense for industrial plants.

Ponding Water Repair

Eliminating dangerous standing water pools by installing tapered polyisocyanurate foam crickets, building up low spots, and adding overflow scuppers.

Flat Roof Insulation

Mechanically fastening rigid polyisocyanurate (polyiso) insulation boards to achieve code-compliant R-30+ thermal performance and reduce building HVAC bills.

Our 6-Step Commercial & Residential Flat Roofing Protocol

  1. Step 1 — Decking Structural Audit & Thermal Moisture Core Scans: We perform non-destructive infrared scans and test core cuts to identify saturated sub-insulation, verifying steel pan or wooden tongue-and-groove deck integrity.
  2. Step 2 — Tapered Polyiso Insulation & Drainage Cricket Layout: To eliminate ponding water, we design and install tapered polyisocyanurate insulation boards engineered with a 1/4-inch per foot slope guiding water toward drains.
  3. Step 3 — High-Strength Cover Board & Mechanical Plate Fastening: High-density gypsum or polyiso cover boards are secured with heavy-duty stress plates and coated screws engineered to withstand North Carolina hurricane wind uplift.
  4. Step 4 — Automated Robotic 1,000°F Hot-Air Seam Welding: On TPO and PVC systems, our robotic hot-air welders fuse membrane overlaps at 1,000°F with consistent speed and pressure, creating permanent molecularly fused watertight seams.
  5. Step 5 — Parapet Wall Encapsulation, HVAC Curbs & Scupper Detailing: Membranes are wrapped up and over parapet walls, reinforced with termination bars, and capped with metal coping. Plumbing boots and HVAC curbs receive welded boots.
  6. Step 6 — 100% Seam Probe Audit & 48-Hour Static Flood Verification: Every inch of welded seam is physically tested with a blunt steel probe to verify weld integrity, followed by drain plugging and static water testing before warranty sign-off.

Frequently Asked Questions

1. How long does a commercial or residential flat roof last in Cary, NC?

A professionally installed 60-mil TPO or PVC flat roof typically lasts 25 to 30 years in North Carolina. EPDM rubber systems average 22 to 28 years, while multi-ply modified bitumen roofs last 20 to 25 years.

2. What is the difference between TPO, EPDM, and PVC flat roofing systems?

TPO (white thermoplastic) is the most popular flat roof in Wake County because its heat-welded seams are exceptionally strong and its bright-white surface reflects summer sun, lowering cooling costs. EPDM is a black synthetic rubber that excels in freeze-thaw elasticity. PVC is chemically impervious to animal fats and grease vents.

3. Why is ponding water dangerous on flat roofs, and how does tapered insulation fix it?

Ponding water (water remaining on a flat roof 48 hours after rain) weighs approximately 5.2 lbs per square foot per inch of depth. We solve ponding water by installing custom tapered polyisocyanurate insulation crickets.

4. How much does flat roof replacement or installation cost per square foot in Cary, NC?

Flat roof installation in Cary typically ranges from $5.50 to $11.00 per square foot for single-ply systems (TPO, EPDM, PVC) and modified bitumen, depending on project scale, accessibility, and insulation thickness.

5. Can you apply a silicone roof coating over an existing flat roof without tear-off?

Yes! If the underlying insulation is dry and structurally sound (verified by our infrared moisture scan), fluid-applied 100% silicone or elastomeric roof coatings can be applied directly.

6. How do you locate and repair hidden leaks on a flat roof?

We inspect all pipe curbs, parapet terminations, and field seams using specialized seam probes, vector mapping, and infrared cameras.

7. What is the best flat roofing material for restaurants or grease-exhaust applications?

PVC (polyvinyl chloride) membrane is the only material recommended for restaurants and food processing facilities because it withstands animal fats and oils without softening.

8. How does flat roof insulation (Polyiso boards) improve commercial energy efficiency in Cary?

Continuous polyiso insulation above the structural deck eliminates thermal bridging through steel joists, keeping heated air inside during winter and blocking radiant sun heat in summer.
