Manufacturing Plant Roofing: Chemical Resistance and Ventilation
Manufacturing plants along DFW's industrial corridors — I-30, I-20, Alliance, and the Great Southwest Industrial District — have roofing demands that office buildings don't. Chemical exposure, heavy ventilation loads, and production-critical scheduling require a roofing contractor who understands industrial facilities.
Chemical Resistance: Why Your Membrane Choice Matters
Most commercial roofing contractors install TPO on everything because it's familiar and competitively priced. For manufacturing facilities with chemical processes, that's a mistake. TPO membranes degrade with hydrocarbon exposure — oils, fuels, and many solvents attack the polymer matrix over time, causing premature brittleness and seam failure. PVC membranes handle the same chemical exposures without degradation. The cost difference between TPO and PVC is roughly 15-20% per square foot — far less than the cost of premature membrane failure. On any manufacturing facility where chemicals are processed, stored, or exhausted through the roof, JRH specifies PVC.
Ventilation: Heavy Loads on Manufacturing Roofs
Manufacturing plants often have more roof penetrations per square foot than any other building type — process exhaust fans, make-up air units, ridge ventilators, combustion air intakes, and dust collection systems. Every penetration is a potential leak point, and the number and size of penetrations on a manufacturing roof can be 5-10x higher than a comparable office building. JRH inventories all penetrations before a manufacturing roof replacement begins and develops a flashing strategy for each type. Oversized penetrations (large process exhaust fans) require custom curb fabrication — we build these in-house rather than waiting on standard stock sizes.
Skylights and Translucent Panels for Industrial Lighting
Many DFW manufacturing plants built in the 1970s-90s have fiberglass translucent panels in the roof deck for natural lighting — a cost-effective alternative to electric lighting for high-bay spaces. These panels degrade over 20-30 years, becoming brittle, yellowed, and eventually fragile enough to be a fall-through hazard. OSHA 29 CFR 1910.23 requires translucent panels over 24 inches wide to be rated for worker weight or covered with fall-protection covers. JRH replaces degraded fiberglass panels as part of manufacturing roof replacements, often upgrading to modern double-wall polycarbonate panels that deliver better light transmission and insulation.
Scheduling Around Production Windows
The most important question for manufacturing plant roofing is: when can we work? JRH schedules around planned maintenance shutdowns, slow production periods, and shift changes to minimize impact on throughput. We can work nights and weekends to keep daytime production running. The key is a detailed pre-project conversation with facility management about production schedules, critical processes, and any periods when work is absolutely prohibited.
