With the roof information in place, the next step is for Roofed Right America to send an inspector to get up on the roofs and perform a condition assessment. No roof can be managed appropriately without knowing its history and understanding its condition, information that comes from conducting a roof inspection. Workers can conduct two types of inspections: visual and non-destructive.
Visual inspections should occur semi-annually or annually, depending on the roof's condition, the amount of rooftop traffic, and the sensitivity of occupants.A Visual roof inspection often includes:
- An examination of the roof system, flashings, sheet-metal flashings, drains, and gutters
- An evaluation of observed conditions that might affect the long-term performance of the roof system
- Documentation of deficiencies requiring corrective action
- Other information needed for developing long-range preventive maintenance (PM) needs.
Non-destructive inspections can complement - but should never replace - visual inspections. Non-destructive measures include infrared, nuclear, and capacitance tests. These inspections can confirm the presence of moisture, establish a baseline for roof management, locate hard-to-find leaks, and authenticate the need for full or partial re-roofing projects. The inspector performing visual roof surveys is very familiar with the design, installation, repair, and types of failure specific to the roof system being surveyed.
