ICRA stands for Infection Control Risk Assessment. In healthcare construction, it is a structured process used to identify and control infection risks created by construction, renovation, maintenance, demolition, or repair activities. The Centers for Disease Control and Prevention (CDC) recommends conducting an ICRA before healthcare construction or repair work that could expose patients to dust or moisture.
For roofing projects, ICRA can become particularly important when roof work takes place above or near occupied patient-care areas, operating rooms, procedure rooms, laboratories, pharmacies, or other sensitive healthcare spaces.
Why Roofing Can Create Infection Risks
Roof replacement and repair can generate dust, debris, moisture, odors, and airborne particles. Tear-off activities can disturb roofing materials and insulation, while drilling and cutting can create additional dust and vibration.
If contaminants enter the healthcare environment through HVAC systems, openings, doors, windows, or building pressure changes, they may affect patients, staff, equipment, or clinical areas.
The CDC notes that an ICRA should consider not only the immediate construction area but also adjacent patient-care areas and spaces on levels above and below the project.
How ICRA Applies to Roofing
An ICRA helps the healthcare facility and project team determine what infection-control measures are appropriate for the specific roofing activity.
The assessment may consider:
-
The type and extent of roofing work
-
The location of patient-care areas below the roof
-
The amount of dust or debris expected
-
Potential moisture intrusion
-
HVAC airflow and pressure relationships
-
Construction access routes
-
Required containment and barriers
-
Patient and staff vulnerability
-
The duration and phasing of the project
The resulting controls should be incorporated into the roofing project’s work plan rather than treated as a separate administrative exercise.
Containment and Barriers
Depending on the risk assessment, roofing work may require physical separation between construction activities and occupied healthcare areas.
The appropriate controls can include temporary barriers, sealed openings, controlled access, dust containment, negative-air or filtration strategies where appropriate, and dedicated construction routes.
The facility’s infection-prevention and facilities teams should determine the controls required for the specific project. ASHE’s ICRA 2.0 process emphasizes an all-team approach to implementing mitigation measures throughout the project.
HVAC and Airflow Considerations
Roofing work can occur close to HVAC equipment, outside-air intakes, exhaust systems, and other components that influence indoor air quality.
Before work begins, the project team should identify air intakes and understand how construction dust or fumes could enter occupied areas. The CDC specifically emphasizes understanding airflow patterns and pressure differentials when managing construction-related infection risks.
Roofing activities near sensitive air-handling equipment may therefore require additional protection or temporary operational adjustments.
Moisture Protection Is Also Important
ICRA is not limited to dust. Water intrusion can create another healthcare construction risk.
During reroofing, portions of the existing roof may be temporarily exposed. If rain enters the building, moisture can damage ceilings, insulation, electrical equipment, or interior finishes and potentially contribute to microbial growth.
Roofing contractors should therefore use controlled phasing, temporary weather protection, and emergency response procedures to keep the healthcare interior protected.
Work Sequencing and Daily Controls
Roofing near healthcare spaces should be carefully phased. Contractors should avoid exposing large areas of the roof unnecessarily and should complete weatherproofing before moving to subsequent sections whenever practical.
Daily coordination among the roofing contractor, facility manager, infection-prevention team, and other project personnel can help confirm that barriers, access routes, ventilation controls, and housekeeping measures remain effective.
Who Should Participate?
ICRA should not be treated as something the roofing contractor completes alone. Healthcare facilities typically involve representatives from infection prevention, facility operations, clinical areas, construction management, and the contractor.
ASHE describes ICRA 2.0 as an all-team process and specifically identifies healthcare administrators, facilities personnel, infection-prevention professionals, and contractor managers among those who may participate.
Conclusion
ICRA is a risk-assessment and infection-control planning process for healthcare construction and maintenance. For roofing projects near occupied healthcare spaces, it helps identify potential exposure to dust, moisture, airborne contaminants, and construction-related disruption and determines appropriate mitigation measures.
For Florida healthcare facilities, roofing contractors should coordinate with the facility’s infection-prevention and construction teams before beginning work. Proper ICRA planning, containment, HVAC coordination, temporary weather protection, controlled access, and phased construction can help protect patients and staff while allowing necessary roof repairs, restoration, or replacement to proceed safely.
