Including all vents, plumbing stacks, gooseneck, and heating vents

Drains are older as well as any flashing on the roof

Lots of standing water around edges of roof lots of organic debris in the standing water areas can see plates and screws under TPO membrane starting to pop

All corners in penetrations have looked like they’ve been replaced before and are now already outdated

Reference pictures for different sizes of flashing

Roof also includes scuppers

And metal flow flashing along the perimeter

Under area of concern from client roof is very soft to walk on has been taken in water for sometime reference pictures. One vent is burnt through the deck and all around the vent open hole from Burn exposed to elements. Need to replace entire area properly would be to replace insulation Wood vent and large TPO patch

Exterior Roof Inspection

Exterior roof inspections assess the visible condition, including damaged shingles/tiles, leaks, flashing, and gutters. Flat roofs require close membrane scrutiny: blisters, cracks, seams, and ponding areas. Check for rot, mold, structural issues, ventilation, and chimney condition. Document findings with photos, noting membrane type and condition. Prioritize safety and thoroughness.

Professional opinion, replacing tire roof with new system and replace Wood where needed clean roof, update all flashing plumbing stacks and drains

Short order quick repair includes immediate area of exposure, at least 3 x 3‘ patch of TPO after cleaning and cutting out burnt TPO and burnt insulation at minimum

Inside building plates and screws can be seen at every penetration as there is no more insulation or drywall present side of building multiple very soft areas. Wood is blackened from burnt and should be replaced.

Some sort of black mastic was used around certain patches, and there is also daylight in some areas

Exterior Roof Materials

Meticulous documentation of the existing roofing system is essential. For color, capture well-lit photos from various angles, noting manufacturer and color names. If unknown, compare physical samples to color charts under natural light. A cut test requires careful removal of a small section, noting material layers, thickness, and degradation. Photograph the cut and surrounding area, recording markings. Additionally, document insulation type (fiberglass, foam, etc.) and thickness. Record fiberboard composition and condition (water damage, delamination). Specify the vapor barrier type (polyethylene, kraft paper) and condition (tears, punctures). During the cut test, examine underlayment and roof deck type (plywood, OSB, etc.). Ensure thorough documentation of all materials for accurate matching and assessment.
