Limited data — grade D
88 Example Grove Court, Allen, TX 75013
We could not measure this roof well enough to print quantities. This report states what is known, what is missing and why.

Why the data is limited
- About 42% of the roof is hidden by tree canopy, over the 30% limit for a graded measurement (05 §6).
- 2 roof lines could not be classified from the geometry; a graded report allows none.
- The imagery source rates its own quality MEDIUM.
What would fix it
- Newer or leaf-off imagery for this address, re-measured and re-graded as a new version at no charge.
- An on-site measurement of the slopes under the canopy.
- A contractor edit that classifies the flagged lines; the edited version is graded on its own merits.
- Acknowledging this notice cannot unlock quantities or prices (VIEW-08).

Why this grade
Grade D: the roof is too hidden to measure from above and some lines could not be typed. Grade D withholds sizes, lengths, prices and orderable quantities.
Automated quality checks
| Automated check | Result | Detail |
|---|---|---|
| Canopy obstruction at most 30% | Failed | About 42% of the roof is under tree canopy in the imagery. |
| Every facet closes | Passed | All 4 facets are closed planar polygons. |
| Every line is classified | Flagged | 11.3% of line length is unclassified. |
| Shared lines counted once | Passed | Ridges, hips and valleys shared by two facets are single lines in every total. |
| Pitch within 0/12 to 24/12 | Passed | Every facet pitch is within the modelled range. |
| Totals recompute exactly | Passed | Withheld: it states a roof quantity (grade D). |
| Structures in scope | Note | Every structure on the property is included. |
| Source | Note | Synthetic sample geometry. A real report states its imagery source, date and quality here. |
Limited data · What is missing
What this report leaves out, and why
88 Example Grove Court, Allen, TX 75013
Not in this report
| Not included | Why |
|---|---|
| Roof area and squares | Withheld at grade D: an untrusted size would be ordered from. |
| Line lengths | Withheld: lines under the canopy are inferred, not seen. |
| Waste allowance | Not computed: it scales an area this report does not state. |
| Material estimate | Not produced: grade D never yields an orderable quantity. |
| Price or cost range | Not shown at grade D, and no acknowledgement unlocks one. |
What would fix it
- Newer or leaf-off imagery for this address, re-measured and re-graded as a new version at no charge.
- An on-site measurement of the slopes under the canopy.
- A contractor edit that classifies the flagged lines; the edited version is graded on its own merits.
- Acknowledging this notice cannot unlock quantities or prices (VIEW-08).
Check at the property
- Measure the slopes under the canopy on site; they are inferred here.
- Confirm how the roof sections meet where lines are flagged as unclassified.
- Confirm the pitch of each slope and the number of roofing layers.
- Note overhanging limbs that affect access, debris and future wear.
Limitations
- Every figure in this sample comes from an invented house built to exercise the report; it is not a surveyed property.
- Measurements come from above: wall heights, decking condition and the number of layers are not visible from the air.
- No accuracy or certification is claimed; a roofer confirms quantities on site before ordering.
