Commercial Roof Due-Diligence Surveys in Gresham, OR

The survey should identify the visit date, areas reached, roof system where known, visible defects, leak evidence supplied by the owner, drainage, penetrations, and prior repairs available for review. Photos need roof-zone labels and enough context for the transaction team to find each item. We list maintenance needs separately from repairs and larger capital concerns. An inaccessible roof, occupied interior, or concealed assembly is called out as a limitation.

We do not convert a short site visit into a structural evaluation or a warranty determination. If the roof has soft areas, visible deflection, or suspected wet insulation, we describe what we observed and whether additional testing or professional review could change the scope. The buyer and seller can decide how to handle those questions within their transaction. A photo-based roof condition report gives the deal team a dated reference with findings and recommended next steps.

Scope also depends on transaction timing. A lender may require a concise condition statement; an acquisition team may need repair pricing or a list of further tests. We confirm the intended use, due date, property access, and deliverable before the inspection. The survey should not imply that every roof zone was inspected if access was limited. If the transaction team needs a repair number by a deadline, we agree which findings require same-day pricing and which depend on testing. This prevents a provisional observation from being mistaken for a construction quantity or an accepted bid.

How is the roof evaluated?

We walk accessible areas and inspect membrane fields, seams, edge metal, drains, scuppers, curbs, penetrations, patches, and equipment supports. On metal roofs, the review follows panel seams, closures, fasteners where visible, and transitions. We compare current findings with available plans, maintenance logs, leak records, and prior reports. Differences between drawings and field conditions are documented for the owner’s review.

Portland International Airport’s NOAA 1991-2020 normals record 36.92 inches of annual precipitation, with most rainfall from fall through spring. That station provides regional climate context for Gresham, not a performance verdict for the building. During the survey, we look at actual drainage, ponding, exposed seams, and water paths. Weather context helps frame questions; the inspection evidence drives the finding.

Drone images may document high elevations or areas obstructed from a safe roof route. Infrared scanning may identify patterns that merit further investigation when weather and assembly conditions permit. Neither method confirms the condition of every concealed layer. If a buyer needs a core or test opening, we state what the test would answer, the proposed location, and how the assembly will be closed after owner approval.
