Guide Structure for Remote Roof Measurements

1. How Remote Roof Measurements Work – Step by Step

Most accurate remote measurement workflows include these steps:

1. Address + Brief
   You enter the roof address and basic requirements (repair, replacement, materials).
2. Imagery Selection
   Latest high-resolution aerial/satellite images are chosen for the target location.
3. Roof Plane Tracing
   Roof edges — eaves, ridges, hips, valleys — are traced on overhead imagery.
4. Pitch Estimation
   Roof slope is estimated with oblique imagery and height references.
5. Area & Linear Measurements
   Square area of roof planes and lineal metres of flashings, edges and features are calculated.
6. Waste & Allowances
   Standard allowances (for cuts, overlaps etc.) are applied.
7. Confidence Level Assigned
   Confidence levels such as “High,” “Moderate,” or “Needs Site Check” indicate reliability.
8. On-site Readiness Check
   Before final pricing, a quick physical check confirms details and access, with provisions if discrepancies exceed a small percentage.

2. What Data You Get from a Remote Measurement

A thorough remote measurement report will generally include:

✅ Roof area (in square metres or feet)
✅ Roof pitch (incline/slopes)
✅ Length of edges (hips, valleys, ridges)
✅ Feature positions (chimneys, skylights, solar panels)
✅ Overall roof geometry and segments
✅ Confidence or uncertainty flags
✅ Wastage and allowance recommendations

This data is crucial for accurate materials and cost estimation.

3. Why Remote Roof Measurements Are Important

Remote measurements save time, money, and safety risk by avoiding the need for initial site visits:

✔ Faster pricing and estimates
✔ Fewer physical site visits required
✔ Good accuracy for pre-inspection quotes
✔ Enables fair competitive quoting by multiple roofers

4. Accuracy & Limitations

Accuracy depends on:

• Quality and date of aerial/satellite imagery
• Roof complexity (many planes or hidden elements)
• Shadows, tree cover, and nearby structures

In complex cases, adding drone photos or a site visit increases confidence.

5. Turning Measurements into Cost

Once the roof is measured, tradespeople use the data to produce a scope of works and final quotes. That often includes:

📍 Material quantity
📍 Labor requirements
📍 Safety/access requirements
📍 Add-on items (flashings, valleys, roof penetrations)

Multiple pre-inspection quotes can be obtained from trusted local contractors on platforms like RoofHero once the measurements are completed.
