Evansville's hospital campuses run surgical suites, imaging equipment, and patient floors underneath roofs that see constant rooftop mechanical traffic. There's very little margin for a mistake up there.
Roof work over an active hospital is about more than keeping water out. It's about keeping dust, debris, and airborne particulate away from air intakes that feed patient floors, and especially surgical suites where positive-pressure air handling has to stay uncompromised. We coordinate directly with a hospital's facilities and infection control staff before any tear-off begins, and we follow whatever ICRA protocol the campus requires, including containment barriers and negative air setups where the work sits near intake louvers.
Cutting and demo work gets scheduled around what's happening below, not the other way around. A section of roof over a surgical wing might only be workable during specific windows the OR schedule allows, and we plan the job around that rather than pushing for our own convenience. That sometimes means a roof project runs longer in calendar days than a comparable commercial job, and we build that reality into the proposal up front rather than surprising a facilities director mid-project.
Hospital roofs carry an unusually dense layout of air handlers, chillers, exhaust fans for surgical suites and labs, and emergency generator exhaust, often stacked closer together than a typical commercial roof because campus additions get built onto existing rooflines over decades. Every one of those units is a penetration, and every penetration is a place a membrane can fail first.
We map rooftop mechanical layouts as part of any hospital roof survey so flashing details get prioritized by what's underneath them, not only by visible wear. A pinhole near a lab exhaust fan gets treated differently than the same size defect over a mechanical penthouse with no occupied space below.
Hospital roofing work leans toward systems with proven track records over experimental products, because a warranty claim process that takes weeks isn't acceptable when the building underneath doesn't stop running. TPO and fully adhered systems dominate hospital re-roofs in this market for that reason, along with the reflectivity benefit for buildings running heavy cooling loads year-round.
For leak calls on active hospital roofs, response time matters more than almost anything else we do. We treat a hospital leak call as urgent by default, because water finding its way into a ceiling above patient care space isn't something that waits for a normal service queue, and we say that to every hospital client at the start of a relationship, not only after the first emergency call.
Hospital campuses carry backup power infrastructure that often extends onto the roof or roof-adjacent structures, from emergency generator exhaust stacks to fuel line penetrations that have to meet a stricter code standard than a typical rooftop vent. We coordinate with a hospital's engineering staff on any roof work near backup power infrastructure, since those systems can't go offline for routine roofing without advance planning through the hospital's own emergency preparedness protocols.
Snow and ice removal near rooftop generator intakes and exhaust also gets handled more carefully on a hospital roof than a standard commercial building, since a blocked exhaust path on backup power equipment is a life-safety issue, not only a maintenance inconvenience.
Where a hospital campus includes a rooftop or adjacent helipad for emergency transport, roof work anywhere near that structure runs under a stricter set of clearance and scheduling rules, since the landing zone can't be obstructed or compromised even temporarily. We coordinate any roof access near a helipad directly with hospital safety officers rather than treating it like a standard rooftop zone.
Lighting, wind sock mounts, and perimeter markings around a helipad are also roof penetrations in their own right, and we flash and maintain those connections with the same care as any other critical rooftop system.
We containment-barrier any work zone near intake louvers and coordinate the negative air setup with your facilities and infection control staff before cutting starts.
Yes. We get the OR and procedure schedule from facilities ahead of time and plan noisy or vibration-heavy work outside those windows.
We treat those calls as priority and move a crew same day whenever possible, because water intrusion above occupied patient space isn't something that can sit in a normal queue.
We complete whatever vendor credentialing and badging process each campus requires before crews are cleared to access the roof.
We map the mechanical layout first and plan foot traffic and material staging around it, rather than treating the roof as an open field.
