JRH Construction installs PVC, TPO, and modified bitumen roof systems on heavy industrial, chemical, manufacturing, food processing, aerospace, and distribution facilities across the Dallas-Fort Worth metroplex. JRH phases every industrial reroof around active production, carries SAM.gov federal registration plus $10 million-plus in bonding capacity, and runs 24/7 emergency response on industrial roofs with crews dispatched within 2 hours.
Heavy vs Light Industrial: How Specification Changes
Industrial roofing specification varies sharply by facility type. Heavy industrial — steel fabrication, foundries, chemical plants, petrochemical processing — produces rooftop chemical exposure from vent stacks, high-temperature exhaust from kilns and furnaces, and HVAC mechanical loads that routinely exceed 40 pounds per square foot. JRH Construction specifies 80-mil PVC on these substrates because PVC resists chemical degradation where TPO fails, and heat-welded PVC seams remain monolithic under thermal cycling.
Light industrial — assembly, packaging, finished-goods manufacturing — carries lower rooftop chemical risk and typically allows 80 to 90-mil TPO over tapered polyisocyanurate insulation at roughly 20 percent lower installed cost than PVC. JRH evaluates rooftop conditions before specification and writes the chemical exposure inventory into the project documentation.
Food processing and cold storage facilities trigger additional protocols. FDA-compliant low-VOC adhesive selection, filtered negative-pressure staging above food-contact zones, and facility QA leadership coordination are all standard on JRH food-grade industrial work.
Industrial Facility Types JRH Handles
Heavy Industrial Manufacturing
Steel fabrication, metalworking, foundry, and heavy equipment manufacturing plants with chemical exposure, high-temperature exhaust, and HVAC-heavy rooftop loads. JRH Construction specifies 80-mil PVC from Sika Sarnafil or IB Roof on these substrates for chemical resistance and heat-welded monolithic seams.
Light Industrial and Assembly
Light assembly, packaging, and finished-goods manufacturing with lower rooftop mechanical density and fewer chemical exposure risks. 80 to 90-mil TPO over tapered polyisocyanurate insulation delivers the cost-to-warranty ratio most light-industrial owners target.
Chemical and Petrochemical Plants
Chemical processing, pharmaceutical, and petrochemical facilities with solvent and acid exposure from rooftop vent stacks. PVC resists these exposures where TPO degrades; JRH specifies 80-mil PVC with chemical-resistant adhesive systems and reinforced penetration flashings at every vent location.
Food Processing and Cold Storage
Food-grade manufacturing and cold-storage warehouse operations requiring zero-contamination tear-off protocols, filtered negative-pressure staging, and FDA-compliant low-VOC adhesive selection. JRH coordinates with facility QA leadership before mobilization.
Distribution and Fulfillment
Large-span distribution and fulfillment centers across the I-35, I-45, and Alliance corridors exceeding 500,000 square feet. JRH handles rooftop skylight integration, HVAC penetration coordination, and phased re-roof around active 24/7 operations in compliance with OSHA fall-protection on production-active roofs.
Aerospace and Defense
Aerospace assembly, defense contractor, and government-adjacent manufacturing with SAM.gov registration and additional-insured requirements. JRH carries SAM.gov federal registration, the required background-check program, and the documentation packages defense-sector clients expect.
HVAC-Heavy Rooftop Loads and Structural Coordination
Industrial roofs carry mechanical loads well above typical commercial buildings. A 100,000 square foot manufacturing plant supports 15 to 30 air-handling units, 4 to 8 process-cooling chillers, miles of refrigerant and steam line, and hundreds of pipe supports. Live load concentrations of 35 to 60 pounds per square foot are routine, with point loads from individual chillers and cooling towers exceeding 8,000 pounds.
JRH Construction coordinates with the structural engineer of record before any industrial reroof to verify deck capacity, quantify dead-load increases from new insulation and overburden, and identify penetrations requiring reinforcement. JRH installs reinforced walkway pads along every maintenance path, integrates sleeper-mounted pipe supports that prevent membrane abrasion, and seals every curb and penetration with lead-coated copper or seamless PVC or TPO flashings carrying the full membrane warranty. JRH retains a licensed Texas professional engineer on staff for stamped load analysis.
OSHA Fall Protection on Production-Active Roofs
Industrial reroof projects on active-production facilities trigger OSHA 29 CFR 1926.501 fall-protection requirements above 6 feet of working surface, plus facility-specific permit-to-work protocols covering hot work under NFPA 241, confined space entry near rooftop mechanical equipment under OSHA 1910.146, and LOTO (lockout-tagout) coordination around rooftop electrical and mechanical tie-ins.
JRH Construction carries OSHA 30 certification on every foreman and superintendent, OSHA 10 on every crew member, a dedicated site safety officer on every industrial project above 20,000 square feet, and an EMR below 1.0 required by most heavy-industrial owners on their approved contractor lists. JRH documents daily safety briefings, toolbox talks, and near-miss reporting inside the facility EHS documentation system throughout project duration.
What roof system does JRH Construction recommend for an industrial manufacturing facility in DFW?
For DFW industrial manufacturing, JRH Construction typically specifies 80-mil PVC from Sika Sarnafil or IB Roof when rooftop chemical exposure is present, and 80 to 90-mil TPO from GAF EverGuard or Carlisle Sure-Weld when exposure is limited. Both systems install with heat-welded monolithic seams over tapered polyisocyanurate insulation at R-30 continuous. Final specification depends on rooftop chemical exposure inventory, HVAC equipment density, expected foot-traffic from maintenance crews, and the owner’s warranty preference between 20-year and 30-year no-dollar-limit coverage.
How does JRH Construction phase a reroof around active industrial operations?
JRH Construction zones the industrial roof into 10,000 to 25,000 square foot work blocks, completes each zone independently while maintaining full waterproofing on all adjacent zones, and schedules high-risk tie-in operations during approved production windows coordinated with plant operations. JRH deploys temporary waterproofing barriers at zone boundaries, keeps emergency tarping materials on site during all active work, and issues daily photo reports to the facility manager. No JRH industrial reroof has caused a facility shutdown event on a plant-active roof.
What is the typical industrial facility reroof timeline in Dallas-Fort Worth?
A 100,000 square foot industrial reroof typically takes 8 to 14 weeks from contract execution to final punch list on an active-production facility. JRH Construction allocates 2 to 3 weeks for material procurement, submittals, and pre-construction coordination; 6 to 10 weeks of phased installation at 8,000 to 15,000 square feet per zone; and 1 to 2 weeks for final inspections, warranty registration, and owner walkthrough. Larger facilities scale linearly — a 500,000 square foot distribution center runs 20 to 28 weeks depending on phasing constraints.
Does JRH handle emergency industrial roof repair in DFW?
Yes. JRH Construction runs 24/7 emergency response on industrial roofs across Dallas-Fort Worth with documented 5-minute phone pickup, crews dispatched within 2 hours, and emergency tarping stocked for immediate deployment. Industrial emergency scopes include active leaks above production lines, HVAC penetration failures, storm-damaged skylights, and emergency drain unblocking during heavy rainfall events. JRH prioritizes 24/7 manufacturing operations where roof failure causes immediate production shutdown losses.
What OSHA and safety protocols apply to industrial roof work on active-production facilities?
Industrial reroof projects on active-production facilities trigger OSHA fall-protection requirements under 29 CFR 1926.501, plus facility-specific permit-to-work protocols covering hot work (NFPA 241), confined space entry near rooftop equipment (OSHA 1910.146), and LOTO (lockout-tagout) coordination around rooftop electrical and mechanical tie-ins. JRH Construction carries OSHA 30 on every foreman, OSHA 10 on every crew member, a dedicated site safety officer on projects above 20,000 square feet, and an EMR under 1.0 required by most heavy-industrial owners on their approved contractor lists.
Does JRH Construction work with chemical and petrochemical facilities?
Yes. JRH Construction installs 80-mil PVC systems from Sika Sarnafil and IB Roof on chemical-exposure industrial roofs across DFW, with chemical-resistant adhesive selection, reinforced flashings at every vent stack and acid-exhaust penetration, and coordination with facility environmental-health-and-safety leadership before mobilization. PVC resists the solvent and acid exposures that cause TPO to degrade — on chemical rooftops, TPO service life falls to 8 to 12 years while PVC holds 25 to 30-year warranty coverage.
What industrial roofing work has JRH Construction completed near Lewisville and the I-35E corridor?
JRH Construction has completed industrial roofing projects across the I-35E corridor through Lewisville, Carrollton, and the Alliance industrial band, including manufacturing facility reroofs, warehouse and distribution center roof replacements, and emergency response scopes during the March 24 2023 and April 26 2024 storm events. [TODO — real project reference needed with owner approval for specific Lewisville project citation]. Lewisville’s industrial concentration along Valley Ridge and the I-35E corridor drives consistent roofing demand, and JRH services that market from the Little Elm headquarters.
What certifications and insurance does JRH hold for industrial facility work?
JRH Construction holds GAF Master Elite (top 2 percent), Owens Corning Platinum Preferred, Carlisle SynTec Authorized Installer, Firestone Red Shield, SAM.gov federal registration, and BBB A+ accreditation since 2019. Insurance coverage includes $10 million-plus bonding capacity, $2 million general liability, $1 million commercial auto, and full Texas workers compensation. JRH carries the safety metrics most heavy-industrial owners require: EMR below 1.0, OSHA 30 on every foreman, zero lost-time incidents on data center work, and a dedicated site safety officer on every industrial project above 20,000 square feet.
