## Two roof systems

The property has approximately 24,536 square feet of TPO roofing and 40,531 square feet of standing-seam metal roofing. The inspection treated each system separately.

## TPO membrane deterioration

The membrane section showed widespread delamination, raised blisters and multiple roofing layers. The replacement recommendation called for tear-off to the deck and inspection of the exposed substrate before installation of a new fully adhered membrane.

## Metal roof valley details

Most of the reviewed valleys showed recurring installation deficiencies along their length. The proposal addressed replacement of the affected metal roof areas with correctly detailed valleys.
