Commercial Roofing
A hospital roof is never the only thing a leak touches: the ceiling below may belong to a patient floor, a supply room or an air handler, and the first question on the phone is which one. Healthcare is among the sectors in the Edinburg, TX employment base, and hospitals operate around the clock in a region where hurricane readiness runs from June through October. A campus can carry several kinds of roof at once: flat roofs on one wing, newer membranes on an addition, and mechanical penthouses with equipment that cannot stop.
We begin with a campus roof drawing that numbers each roof area and names what sits under it. Leaks are traced from the stain back across the roof, and every finding is placed in a photo record tied to that drawing.
Hospital campuses tend to grow by additions, and the roofs show the joints. The first failures are at the places where one roof meets another: a lower roof beside a taller wall, an expansion joint between wings, a connector corridor roof tied into an older building. Each is a roof-to-wall or roof-to-roof transition that moves differently on each side.
Beyond those, the usual suspects are rooftop equipment curbs, exhaust and relief air outlets, drains that serve large areas and penetrations for medical gas, electrical and plumbing lines. Expansion joints in particular are hard to detail and easy to damage. We look at each transition, photograph the movement and mark which joints have cracked sealant or open flashing. A repair that restores the joint with a flexible, properly terminated detail is more durable than adding more sealant. Equipment openings get penetration and skylight flashing work.
On a patient floor, ceilings stay closed and the stain is the only clue. We ask the facilities team for the location, the date, the weather and any leak history for that area, then compare with the roof drawing. Water in a hospital ceiling can travel along ducts, sprinkler mains, conduit and medical gas lines, so the stain may be far from the roof opening.
On the roof, we walk the line from the stain upslope, checking each curb, drain, seam and wall transition. A moisture survey shows the extent of wet insulation, which tells us whether the problem is local. Because wet materials above patient areas need prompt attention, we tell the facilities team about any moisture readings that suggest the ceiling space is affected, and the interior review is handled by the people responsible for it. An infrared moisture survey scans large roofs without opening them, which suits a campus that cannot easily close areas.
A campus inspection is divided by building and roof level. Each roof area gets a number, an age if known, a membrane type and a condition rating. We photograph the whole roof from the access point, then walk the perimeter, equipment, drains, seams and transitions in a fixed order, so results compare from one year to the next.
The record ranks roofs by condition and by what sits below, so the facilities director can budget and sequence work across the campus. A drone roof inspection helps with the first pass on larger roofs, and hands-on walks confirm the findings. Where a roof is flagged, the next step is moisture testing and a repair scope.
Cooling is critical in a hospital, and from May into October, when the Valley is under heat-safety guidance, a roof that absorbs heat adds to that load. The same months age sealants and push the daily swing in size that works on joints and flashings.
Dolly's 50-to-70-mph gusts crossed Hidalgo County, and Hanna's July 2020 wind and flooding hit Edinburg itself. For a hospital, preparation is a pre-season routine: drains cleared, edge metal and equipment fastened, loose items removed and temporary protection staged. After a storm, we check edges, flashings and rooftop equipment before we look at the membrane. A hurricane damage repair record documents the condition for the facilities team and any insurer.
Repair boundaries follow moisture and membrane condition, with a lower tolerance above sensitive areas. A localized leak is repaired at the source and the surrounding insulation is dried or replaced. When a roof has recurring leaks, widespread wet insulation or aged membrane, the owner compares ongoing repairs with a phased roof replacement or a recover where the existing roof allows.
A phased plan opens one area at a time, in an order that keeps critical spaces dry and keeps work away from them in peak weather. Price follows the layers to remove, how much insulation is wet, the equipment that must be lifted, access, and the time it takes to coordinate with the facilities team. Each phase is described with the rooms below it, the protection in place and the evidence for the choice. On a campus, the order of phases also follows the building's own plans: a wing slated for interior renovation should not receive a new roof the year before, and a roof over a planned addition should get only the repairs that keep it dry until the tie-in is built. Asking the facilities director for the capital calendar early lets the roof plan fit it.
Hospitals have infection-control rules for construction work, and a roofing project is subject to them where it affects air handling or interior spaces. We ask for the facility's rules and risk assessment before mobilizing, and we plan intake covers, debris control and noise limits to match. Dust and fumes are kept away from air intakes, and work above sensitive areas is scheduled to minimize exposure.
Ambulance lanes, entrances and parking are mapped and kept clear. Lifts and staging are placed with the facilities team, and material deliveries are scheduled around visiting hours and shift changes. A roof section opens only when it can be dried in by day's end. Times are logged for the facilities file, and an owner with buildings in Edinburg and McAllen can keep one record format across all of them. A smaller practice building follows the same method as medical office roofing, and a campus with a server room follows data center roofing for that zone.
Yes, with planning. We follow the facility's infection-control rules, work in sections and close each one the same day.
They have to move without opening. When sealant cracks or flashing separates, water follows the joint into the building.
We respond at the roof, protect the opening and tell the facilities team about any moisture that may be in the ceiling space so they can act.
By condition and by what sits below. The record puts roofs over sensitive areas and roofs with active leaks at the front of the list.
The city reviews the permit under the 2018 building and energy codes it has adopted, and the phase plan spells out insulation and edge details for each wing so the reviewer sees them early.
