Full tear-off and replacement of commercial flat roofs across the Louisville metro — TPO, EPDM, PVC, modified bitumen — with manufacturer-warranty closeout and documented capital handoff.
Full-system tear-off and replacement on Louisville commercial flat roofs — scoped against your capital horizon, sequenced around Louisville's freeze-thaw and ice-storm exposure, and closed out with manufacturer warranty documentation that holds up over time.
Most commercial roof replacements in the Louisville area get scoped reactively. The roof leaks after an ice storm, someone calls three contractors, and the lowest bid wins. That replacement runs the same membrane on the same insulation with the same parapet detailing — and then leaks again in two seasons. We do not work that way.
Our replacement scope starts with a documented roof walk and moisture-core pulls on any roof where we suspect saturated insulation. Louisville's climate creates a specific failure pattern: water infiltrates through ice-dam-damaged flashings or open laps in shoulder season, saturates insulation through winter, and accelerates membrane degradation through the following summer. We document deck condition, parapet flashing condition, drain status, every penetration, and every prior repair before a scope is written.
The deliverable at closeout is the warranty document, the roof zone diagram with all closeout photos keyed to it, the maintenance contract, and a written record the next building owner can build against — not a stack of receipts that has to be reconstructed from scratch.
Recover-versus-replace is the first decision in any aging-roof scope. We pull moisture cores in five to ten representative locations on roofs we suspect have insulation saturation. If more than 25% of cores read wet, replacement is the honest scope — recovering wet insulation traps moisture and voids the new warranty. If under 25%, a recover with targeted insulation replacement at wet areas can extend the asset another 15-20 years at roughly half the capital cost of full replacement.
Louisville's freeze-thaw cycling creates deck-condition issues that older DFW or Gulf Coast specs do not anticipate. We pull deck inspection ports under wet cores and at deflection points. Metal deck that has seen repeated condensation-cycle exposure corrodes from the bottom up — not visible from the roof surface until it fails under load. Owners need to know deck condition before the project starts, not when the crew opens up the roof and stops work.
Membrane: TPO 60-mil or 80-mil for most Louisville commercial buildings; EPDM 60-mil or 90-mil for industrial buildings with high mechanical traffic or chemical exposure — EPDM performs better in Louisville's wide temperature swings than it does in hotter markets; PVC 50-mil or 60-mil for restaurants and high-chemical-exposure applications; modified bitumen torch-down or cold-applied for buildings with existing BUR systems where the recover path makes sense. We are not married to any manufacturer — we specify based on building use, warranty terms, and what the capital horizon supports.
Insulation: We spec to current Kentucky energy code (ASHRAE 90.1 / IECC 2021, minimum R-25 for low-slope commercial). The stack typically runs polyiso primary insulation plus a cover board, with tapered polyiso packages designed against the actual drain layout and documented ponding patterns. Louisville's temperature swings (routinely from -5°F to 95°F in the same building year) require insulation joints and vapor-retarder details that some warmer-market specs skip.
Fastener pattern: Designed against IBC 2021 wind-uplift requirements for the building's zone and exposure category. Jefferson County buildings at open exposures or near the Ohio River corridor get more conservative fastener density to account for channeled wind from the river valley.
Pre-construction: Permits filed with Louisville Metro or the relevant municipality (Louisville/Jefferson County Metro Government handles most permits in the core; Jeffersontown, St. Matthews, Anchorage have separate processes). Pre-job meeting with the facility manager to set crane and material lay-down zones, tenant notification, and weather-window planning — critical in Louisville's shoulder seasons where a three-day ice forecast can delay dry-in.
Production: Tear-off staged in sections small enough for same-day dry-in. Louisville gets spring hail events and winter ice storms with minimal warning — we do not leave the building exposed overnight. Summer production runs early-morning start times to work before afternoon thunderstorm risk increases.
Closeout: Punch walk with facility manager and project manager, manufacturer warranty inspection with the manufacturer's field rep, closeout package delivered: warranty document, photo-keyed zone diagram, maintenance contract, manufacturer start-up documentation.
Ice storms are the primary weather constraint on Louisville commercial replacement work. We pull the NOAA forecast and will not start a tear-off section we cannot dry-in the same day if there is any ice or freezing rain in the 48-hour window. We also avoid starting new sections in the 24 hours before any sub-freezing precipitation. The scheduling impact is real — some owners want a late-October or November start, and we advise against it because the dry-in risk is too high. We are honest about this before contract signing.
No. We tear off only what we can dry-in the same day. Each section gets a temporary dry-in — single-ply membrane lap with mechanical fasteners — at end of day. We do not leave the building interior exposed overnight. If a storm approaches faster than forecast, we stop tear-off and dry-in what is open before the weather arrives.
UPS Worldport, the Ford plants, Norton Healthcare, Baptist Health, and UofL Health all operate formal vendor programs with approved contractor lists, documentation requirements, and safety protocols. We participate in those programs and document our work to the standards those programs require. If your building is part of an institutional portfolio, we can walk through what the program requires and how our process fits.
