Why Dallas-Fort Worth Is the Second-Largest U.S. Data Center Market
Dallas-Fort Worth surpassed Silicon Valley, Chicago, and Atlanta in commissioned data center capacity in 2023 and now trails only Northern Virginia among North American markets. The DFW metroplex hosts more than 184 operational data center facilities concentrated in four submarkets: Plano and Richardson along the Telecom Corridor, Irving and Las Colinas along State Highway 114, the Alliance corridor in north Fort Worth, and the southern growth band through Ellis and Johnson counties.
Major operators with DFW footprints include Stack Infrastructure, Aligned Data Centers, Digital Realty, Equinix, Prime Data Centers, QTS, CoreSite, CyrusOne, and Meta. Combined, these operators run more than 9,000 megawatts of IT load across the region, with additional capacity under active construction through 2027. Every megawatt of capacity translates to roughly 10,000 to 15,000 square feet of roof area that must perform without failure for 20 years or more.
The DFW climate compounds the engineering challenge. North Texas averages 14 hail days annually — more than triple the national average — with peak hail sizes regularly exceeding two inches during spring supercell season. Summer rooftop surface temperatures on dark membranes reach 180°F, accelerating seam fatigue and insulation board warp. A data center roof specified for Ohio or New Jersey will not survive a decade in Dallas.
Which Roof System Is Right for a Hyperscale Data Center?
JRH Construction installs three primary roof systems on DFW data centers. The right specification depends on facility tier rating, mechanical equipment density, rooftop chemical exposure, and the operator’s warranty preference. A side-by-side comparison drives the final recommendation.
| System | Best For | Warranty | Installed Cost Range |
|---|
| 80–90 mil TPO (GAF EverGuard, Carlisle Sure-Weld) | Standard Tier II and Tier III data centers, hyperscale shells | 20–30 year NDL | $12–$18 / sq ft |
| 80 mil PVC (Sika Sarnafil, IB Roof) | Facilities with rooftop chemical exposure, Tier IV redundancy | 25–30 year NDL | $15–$22 / sq ft |
| Modified Bitumen 2-ply SBS (Firestone, GAF Ruberoid) | High-traffic mechanical penthouse areas, re-cover over existing | 20 year NDL | $10–$15 / sq ft |
Cost ranges reflect DFW market pricing for projects above 20,000 square feet as of Q1 2026. Final pricing depends on insulation R-value, deck condition, penetration count, and phasing requirements.
How Do Tier III and Tier IV Hail-Impact Ratings Work?
The FM Approvals Standard 4470 governs impact resistance for single-ply roof membranes, with Class 4 as the highest classification. A Class 4 membrane must survive a 2-inch steel ball dropped from 20 feet without puncturing — a test that replicates the impact energy of a large hailstone striking at terminal velocity. JRH Construction specifies FM 4470 Class 4 membranes on every Tier III and Tier IV data center project in the DFW region. Insurance carriers including FM Global, Zurich, and AIG offer premium reductions of 10 to 25 percent on Class 4 rated assemblies.
Uplift classification matters equally. FM 1-90 requires the full roof assembly — membrane, insulation, fasteners, and deck attachment — to resist a 90 pounds-per-square-foot uplift load without failure. On open-site hyperscale campuses in Ellis County or Alliance, local wind-speed design maps require FM 1-120 or FM 1-150 on corner and perimeter zones. JRH engineers every data center roof to the stricter of ASCE 7-22 and the manufacturer’s published uplift chart.
What Safety Requirements Apply to Data Center Construction Sites?
Hyperscale operators enforce safety standards that exceed OSHA minimums. Most require an experience modification rate (EMR) below 1.0, documented OSHA 30 certification for every foreman, and zero lost-time incidents in the prior 24 months. JRH Construction meets every threshold: current EMR is below 1.0, every foreman and superintendent holds OSHA 30, and JRH has logged zero data center lost-time incidents across all DFW projects.
- Background checks and NDAs: Every crew member clears a criminal background check and signs facility-specific non-disclosure agreements before first badge issuance.
- Photography and device restrictions: JRH enforces no-photo zones on secure facility work, with phones and cameras locked during site hours when required.
- Hot-work permits: Torch-down modified bitumen requires fire watch, extinguisher staging, and 30-minute post-work monitoring per NFPA 241.
- Escorted access: JRH crews follow operator access procedures including badge-in, badge-out, daily tool inventory, and supervised entry into critical zones.
- Site safety officer: Every JRH project above 20,000 square feet carries a dedicated safety officer separate from the production superintendent.
How Does HVAC-Heavy Rooftop Equipment Affect Roof Design?
Data center roofs carry far more mechanical equipment than typical commercial buildings. A 100,000 square foot hyperscale data hall supports 40 to 60 air-handling units, 8 to 12 chillers, miles of refrigerant line, and thousands of pipe supports. Live load concentrations of 35 to 60 pounds per square foot on roof deck structure are routine, with point loads from individual CRAC units exceeding 4,000 pounds.
JRH Construction coordinates with the structural engineer of record before any re-roof to verify deck capacity, quantify dead-load increases from new insulation and overburden, and identify penetrations that require reinforcement. JRH installs reinforced walkway pads along every service path, integrates sleeper-mounted pipe supports that prevent membrane abrasion, and seals every curb and penetration with lead-coated copper or seamless TPO flashings that carry the full membrane warranty.
JRH retains a licensed Texas professional engineer on staff for load analysis, structural review, and stamped drawings where required by the authority having jurisdiction.
New Build, Re-Roof, or Restoration: Which Does Your Facility Need?
Most DFW data center work in 2026 is re-roofing, not new construction. Facilities commissioned between 2005 and 2015 are reaching the end of their original TPO warranty period, and insurance carriers are demanding upgrades to Class 4 hail-impact ratings and reflective white surfaces. JRH Construction recommends one of three paths based on deck condition, insulation moisture content, and remaining membrane life.
- New construction roof installation. For ground-up data center builds, JRH installs the complete roof assembly from deck up, coordinates with MEP trades on penetrations, and delivers warranty inspection and registration at turnover.
- Full tear-off and replacement. When insulation is wet, the deck shows corrosion, or the existing membrane has failed, JRH removes the entire roof assembly down to deck and installs a new specified system under a 20 to 30-year NDL warranty.
- Recover over existing. When the existing assembly is sound and the structural engineer approves the added load, JRH installs a new membrane over the existing substrate, saving 30 to 40 percent of tear-off cost and avoiding operational disruption.
- Silicone or polyurethane restoration coating. On roofs with remaining service life and minor defects, JRH applies Henry 587 silicone or GAF Unisil at 2.5 gallons per square, restoring waterproofing and qualifying the roof for a new 10 to 15-year warranty at roughly one-third the cost of replacement.

Data Center Roofing FAQ
What is the best roof system for a data center in Texas?
The best roof system for a Texas data center in 2026 is 80-mil or 90-mil TPO membrane over tapered polyisocyanurate insulation, with a white reflective surface rated at 0.78 initial solar reflectance or higher. TPO delivers 20 to 30-year manufacturer warranties from GAF EverGuard, Carlisle Sure-Weld, and Firestone UltraPly, installs heat-welded for monolithic waterproofing, and meets FM Global 1-90 uplift classification required by hyperscale operators in the DFW region. JRH Construction specifies 90-mil TPO on Tier III and Tier IV facilities and 80-mil on standard colocation builds.
How does hail affect data center roofs in Dallas-Fort Worth?
Hailstones exceeding 1.75 inches in diameter — common in the DFW spring storm season between March and June — can puncture standard 45-mil TPO, compromise single-ply seams, and fracture the polyisocyanurate insulation board beneath the membrane. On data center roofs, a single puncture above the electrical room or battery plant can cause millions of dollars in downtime losses. JRH Construction specifies FM 4470 Class 4 impact-rated membranes, ballasted or mechanically fastened assemblies tested against 2-inch hail impacts, and recommends biannual post-storm inspections for every DFW data center client.
Can you work on a Tier III or Tier IV data center without disrupting operations?
Yes. JRH Construction uses a phased installation methodology that divides the roof into zones and completes each zone independently while maintaining full waterproofing integrity on all adjacent zones. JRH deploys temporary waterproofing barriers at zone boundaries, keeps emergency tarping materials on-site during all active work, and schedules high-risk tie-in operations during approved maintenance windows coordinated with the facility operations team. No JRH data center client has experienced a facility downtime event attributable to roofing work.
What is the typical project timeline for a 50,000 square foot data center roof replacement?
A 50,000 square foot data center re-roof typically takes 6 to 10 weeks from contract execution to final punch list, assuming standard weather conditions. JRH Construction schedules two weeks for material procurement and submittal approvals, four to six weeks of phased installation with 5,000 to 8,000 square feet per zone, and one to two weeks for final inspections, warranty registration, and operations-team walkthrough. JRH provides daily photo reports and a Monday-morning project dashboard to the facility manager throughout the build.
What insurance and bonding do you carry for data center projects?
JRH Construction carries $10 million in bonding capacity, $2 million in general liability insurance, $1 million in commercial auto coverage, and full Texas workers compensation on every crew member. JRH is SAM.gov registered for federal contracts and holds additional insured endorsements available for hyperscale and Fortune 500 facility operators. Certificates of insurance are issued within 24 hours of request, and JRH routinely meets the elevated coverage thresholds required by Stack Infrastructure, Digital Realty, Equinix, and Aligned Data Centers.
How do you handle rooftop HVAC units and heavy mechanical equipment on data center roofs?
Data center roofs carry extraordinary mechanical loads — typically 35 to 60 pounds per square foot of CRAC units, chiller lines, and air-handling equipment concentrated near mechanical zones. JRH Construction coordinates with the structural engineer of record before any re-roof, specifies reinforced walkway pads along all service paths, installs lead-coated-copper or seamless TPO flashings at every curb and penetration, and integrates new sleeper-mounted refrigerant line supports that prevent membrane abrasion. JRH retains a licensed Texas professional engineer on staff for load and penetration analysis.
What safety credentials do your crews carry for mission-critical construction sites?
Every JRH Construction crew member holds OSHA 10 certification at minimum, with foremen and superintendents carrying OSHA 30. JRH maintains an experience modification rate (EMR) under 1.0 — required by most hyperscale operators — and documents zero lost-time incidents on data center work. Crews pass background checks, sign facility-specific NDAs, comply with photography and mobile-device restrictions, and follow escorted-access procedures on badge-controlled sites. JRH provides a dedicated site safety officer on every project above 20,000 square feet.
Do you handle data center re-roofing or only new construction?
JRH Construction handles both. Re-roofing represents the majority of JRH data center work in Dallas-Fort Worth because the region's oldest hyperscale and colocation facilities — built between 2005 and 2015 — are now reaching the end of their original 15 to 20-year TPO warranties. JRH performs tear-off and replacement, recover systems over sound existing substrates, and full restoration coatings using Henry 587 silicone or GAF Unisil on roofs with remaining service life. JRH also installs new-construction roof systems on ground-up data center builds in the DFW growth corridor.
