Visual Flat Roof Inspections

A visual survey 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.

Survey documentation consists of a written report or checklist, photographs and notes on a roof plan indicating the conditions observed. The roof plan will supply enough data to enable the performance of the required repairs.

By noting the perimeters of all roof sections, as well as the location of all major rooftop equipment, an accurate and detailed roof plan becomes an important piece of the management puzzle. In the event repairs require the presence of a roofing professional, this plan can serve as the basis of a punch-list for the contractor.

The frequency of tasks associated with roof PM depends on the roof's age and condition, environmental conditions, rooftop traffic, occupancy sensitivity, size, and roof accessibility.
