For Solar Installers

Solar-ready roof data. Per plane. Per pitch.

Pitch, azimuth, compass direction and area for every roof plane, from Google Solar API data. Review a home's usable roof faces before you open your design tool.

Built for the way you work

Per-plane pitch & azimuth

Each facet is listed with pitch as a ratio and in degrees, azimuth in degrees, compass direction, height and area in square feet.

Roof area by direction

The report totals roof area by compass direction, so you can see how much south-, east- and west-facing roof a home has at a glance.

Imagery date and quality shown

Every report lists the Google imagery date and quality level. If the imagery is older, check for additions, new trees or a replaced roof before quoting.

$6.99 per address

No subscription. Buy one report at a time or a $29 five-report pack, and add your company logo to the PDFs you share with homeowners.

What you get in every report

  • Pitch per roof plane, as a ratio and in degrees
  • Azimuth (0–360°) and compass direction for each plane
  • Area per plane and roof area totaled by direction
  • Ridge, hip, valley, eave and rake lengths
  • Detached garages and other secondary structures listed separately
  • Data-quality page with imagery date, quality and any manual adjustments

How solar installers use FastRoofReport

  1. 1

    Confirm the building

    Enter the address and check the satellite map shows the right home. Note detached garages or additions that may be better or worse candidates for panels.

  2. 2

    Review the roof planes

    Look over the detected planes. Facets with an unusual pitch are flagged so you can keep, remove or snap them to the main roof pitch before relying on the totals.

  3. 3

    Shortlist planes by direction and pitch

    Use azimuth and the area-by-direction summary to find the south-, east- and west-facing planes worth modeling, and their pitch in degrees.

  4. 4

    Model it in your design software

    Enter plane pitch, azimuth and dimensions into your PV layout and production tool, then apply your local fire-code setbacks and shading analysis there.

  5. 5

    Verify on site before final drawings

    Confirm plane dimensions, obstructions and roof condition during the site survey before permit drawings or equipment orders.

What FastRoofReport does not do for solar

  • No shading, irradiance or energy production estimates — use your solar design software for those.
  • No panel layout, fire-code setbacks or string design.
  • No structural, rafter or electrical service assessment.
  • Vents, skylights and chimneys are visible in the imagery but are not measured as separate items; check them on site.

Frequently asked questions

Does FastRoofReport include pitch and azimuth for solar design?

Yes. The report's Pitch & Direction page lists every roof plane with its pitch as a ratio (for example 6/12) and in degrees, its azimuth from 0–360°, a compass direction, height and area in square feet — the plane inputs most PV layout tools ask for.

What pitch in degrees is a 6/12 roof?

About 26.6°. Other common conversions: 4/12 is about 18.4°, 8/12 is about 33.7° and 12/12 is 45°. FastRoofReport shows both the ratio and the degree value for each plane, so you don't have to convert by hand.

How do I read azimuth in the report?

Azimuth is the compass direction a plane faces, measured clockwise from north: 90° faces east, 180° faces south and 270° faces west. The report also totals roof area by direction, so you can see how much south-, east- and west-facing roof a home has.

How is this different from Google Project Sunroof?

Project Sunroof is a homeowner-facing savings estimate. FastRoofReport uses Google Solar API roof data to produce a downloadable PDF with per-plane pitch, azimuth and area, edge lengths, secondary structures and a data-quality page showing the imagery date and quality.

Can I use these measurements for a permit submittal?

Use the report as a starting point for preliminary layout, then verify on site before final permit drawings. Fire-code setbacks, structural requirements and drawing standards come from your local authority having jurisdiction, not from a satellite report.

Does FastRoofReport calculate shading or solar production?

No. FastRoofReport measures roof geometry. The satellite map lets you see trees, chimneys and neighboring buildings in context, but shading, irradiance and production estimates should come from your solar design software.
