Storms involving rain, wind, snow, ice, hail and a combination of environmental factors result in millions of dollars in property damage and the interruption of services and operations.
Your roof should be designed, constructed and maintained to defend against the environmental conditions of the local region. Roof and equipment damage along with moisture leaking into the building can pose a significant risk to the building and occupants.
These risks can be managed through ongoing roof assessments.
Your facility’s roof is an important area where you can control risk simply by conducting inspections. It is considered a best practice to have every roof routinely inspected to ensure that the:
- roofing material is properly in place
- flashing is adequate
- roof drains are clear of debris
Roof inspections should be completed at least annually and after major storms. Each inspection should be documented with a checklist and photos if possible, and documentation should be keep on hand for future reference and review.
The safety of individuals who are working on a roof is of the utmost importance. Roofing contractors who have the proper equipment, experience and training can be used to complete the roof inspections and documentation. The roofing contractor should be qualified and licensed, meeting local, state and Federal requirements. To limit your organization’s exposure, the contractor should provide certificates of insurance for general liability and workers' compensation.
A Roof Assessment Checklist is provided here for use in documenting the roof condition. The Checklist can also be used to initiate actions needed to maintain the roof so that storms do not result in unexpected damage to the property and associated injury to the occupants or the general public.
Roof Assessment Checklist
- Are there any cracks, splits or loose seams in the roof covering?
- Is there any blistering (may resemble bubbles) of the roof covering?
- Is there any ponding or other evidence of water accumulation?
- Are drains plugged or potentially blocked by debris or other material?
- Are there any bare spots in the gravel or stone covering?
- Is there any evidence of damage by hail?
- Are gutters and downspouts intact and clear of leaves or other obstructive materials?
- Is there any loose or missing flashing around the edges (top and sides), especially near the corners?
- Are there any signs, antennas, microwave dishes, or other roof-mounted equipment with loose or disconnected supports or guy wires?
- Is there any evidence of leaking on the top floor of the building?
Note: Avoid torch-applied roof coverings. If it is necessary to use a torch to repair an existing roof or install a new covering, a fire watch should be conducted at least 30 minutes past completion of the work. Multiple fire extinguishers should be
