Flat Roof Inspection Logger
Low-slope roof walkdown — membrane, seams, flashings, drains, ponding and rooftop traffic damage; zone-tagged offline log with exports.
New roof zone inspection
Twice yearly (spring/fall) plus after major storms and any rooftop trade work — the NRCA rhythm.
Field guide: Flat Roof Inspection Logger
Roofs rarely fail in the field of the membrane — they fail at the details: base flashings, pitch pans, the penetration the HVAC contractor added in March and sealed with optimism. The classic study finding holds that the vast majority of leaks trace to flashings and penetrations, which is why this logger gives details their own panel and treats 'new unsealed penetration' as a top-class finding. The other chronic villain is water that can't leave: ponding past 48 hours voids many warranties and accelerates every membrane chemistry.
The traffic panel encodes the awkward truth that other trades cause a huge share of roof damage — dropped screws through membrane near fresh unit work tell a dated story your warranty claim needs. Soft, spongy areas underfoot mean wet insulation: the leak happened a while ago and the roof is now storing it. Zone-tagged entries (GPS works fine on a roof) map interior stain reports to the details above them.
Field tips
- Walk the roof within a day after rain — ponding outlines and active details show themselves; bone-dry inspections flatter every roof.
- Check drains FIRST in fall: one clogged drain plus one blocked overflow scupper is a structural loading event, not a leak.
- Photograph trade debris (screws, knife cuts, gasket bits) where it lies near recent work — date-stamped evidence settles backcharges.

Frequently asked questions
How fast does ponding water damage a roof?+
The 48-hour benchmark is industry-wide: water remaining beyond that accelerates membrane aging (UV+water), concentrates dirt that holds moisture, finds every micro-defect, and adds dead load. Most manufacturer warranties exclude damage in chronic ponding areas — making your dated ponding photos either a slope-correction case or a warranty fight you'll lose.
Why do pitch pans fail so reliably?+
They're filled with sealant that shrinks and dries while the penetration moves with thermal cycles — a maintenance item by design. Dried, cracked pitch-pan filler is among the most common leak sources found in surveys. Logging them by zone feeds the semi-annual top-up that keeps a $5 fix from becoming wet insulation.
What does soft or spongy decking underfoot mean?+
Wet insulation — the membrane leaked at some point and the assembly is holding water. It kills R-value, corrodes steel decks and adds weight. Mark the boundary (moisture scans refine it), because repairs that ignore saturated insulation entomb the problem. 'Soft underfoot' findings should always trigger investigation, not patching alone.
How should rooftop trade work be controlled?+
A roof-access protocol: log who goes up and why, require walk pads/protection during work, and inspect the work area after every trade visit — the same week. Most punctures are found months later when ceilings stain; same-week inspection plus this log's dated entries converts them into the contractor's repair, not your reroof.
