Multi-Slope Roof Inspection Tactics That Catch Every Dollar

The roof with 4 simple slopes pays the bills. The roof with 14 slopes, 3 dormers, 2 chimneys, and a valley you did not see from the ladder pays the mortgage. Miss one facet on a cut-up roof and you are leaving 15 to 30 percent of the supplement on the table. Worse, the adjuster will cite your incomplete photo set as evidence the damage does not extend to the slope you forgot to climb.

This is a field guide for inspecting complex roofs the right way: gable vs hip geometry, the walk order that does not double back, the photo sequence adjusters accept on the first submission, and the measurement workflow that ties it all together.

Know the geometry before you climb

Before you set a ladder, stand in the driveway and count facets. A gable roof has 2 sloped planes meeting at a ridge with triangular end walls. A hip roof has 4 sloped planes meeting at a ridge or a point, no end walls. Most production homes built after 2005 are modified hip: primary hip with gable dormers, hip-on-gable crossings, or Dutch gables where a small gable caps a hip.

Count from the ground:

• Front elevation facets
• Back elevation facets
• Left gable or hip return
• Right gable or hip return
• Dormer faces (each dormer has 2 to 3 planes)
• Porch or patio cover slopes
• Garage or bump-out slopes

Write the count on your tablet or notebook. A 14-facet house should produce at least 14 slope-overview photos plus close-ups. If you come down with 9 photos, you missed something.

The walk order that covers everything once

Pick a starting corner, usually the front-left at the eave, and walk clockwise around the perimeter of each roof plane. Never cross a ridge mid-slope. Ridges are transition points where you stop, document, and start the next plane.

1. Climb to the lowest eave on the front elevation.
2. Walk the perimeter of that slope clockwise: eave to left rake, rake to ridge, ridge to right rake, rake back to eave.
3. At the ridge, transition to the back slope and repeat.
4. Work outward to hip slopes, then dormers, then accessory structures.

On a 12/12 or steeper pitch, rope up. A harness and a ridge anchor with 30 feet of 1/2-inch rope costs around $180 and is cheaper than the deductible on one workers comp claim. A dedicated roof harness kit with ridge hook pays for itself in the first storm season.

Photo ordering adjusters accept

Every slope gets the same 4-photo sequence, in this order:

1. Slope overview from the ridge looking toward the eave, wide enough to show the full plane
2. Test square with chalk: a 10-foot by 10-foot box drawn on the slope showing hit count within
3. Close-up of the 3 most severe hits inside the test square, dime or quarter for scale
4. Contextual shot showing slope orientation (north, south, east, west) and any penetrations

Name the photos in your inspection app using a consistent scheme: front-left-gable_01_overview, front-left-gable_02_test-square. RoofKnockers auto-tags photos by slope and tags a GPS coordinate to each, which kills the argument that the photos came from a different house.

Measurement tool workflow

A CompanyCam photo is not a measurement. You need a verified square-count report before the supplement goes in. The sequence:

1. Order an EagleView or Hover report before you leave the driveway (24 to 48 hour turnaround, around $22 to $38 depending on complexity)
2. While waiting, sketch the roof on graph paper with approximate measurements using a tape or laser
3. When the report arrives, compare your sketch to the facet count on the report. Mismatches mean you missed a slope.
4. Upload the report into the job file with your photos

For roofs over 40 squares or 15 facets, spring for a complex or premium report tier. The extra $10 buys you diagram accuracy that survives an adjuster review.

Why missing a slope costs 15 to 30 percent

Say a 42-square roof with 12 facets has hail damage on 10 of 12 slopes. You document 9 slopes. The adjuster approves replacement for 9 slopes at roughly 35 squares and writes the 10th slope off as undamaged. You just lost 7 squares at an average RCV of $525 per square: $3,675 on a single job. Multiply by 3 jobs a month you could have caught and the annual cost is over $130,000 in supplement dollars you handed back.

Special cases

Dormers

Dormers have 2 cheek walls and 1 or 2 roof faces, plus saddle flashing where the dormer meets the main roof. Photograph each face separately and the saddle flashing from 3 angles. Cracked saddle flashing is a supplement line item at $18 to $28 per linear foot.

Valleys

A valley is not a slope, but it gets its own photo: the full length from ridge to eave, plus close-ups of any granule loss in the valley metal. Open valleys with metal need the metal condition documented; closed valleys need the shingle condition above the valley line.

Porches and patios

A detached porch slope is still part of the claim if the porch is attached to the main structure. Most rookies skip porch roofs because the pitch is low and they figure the adjuster will lump it in. The adjuster will not. Treat every attached slope as its own documented slope.

Tools that pay off

• Chalk for test squares: keep a 2-color set so test squares are visible in photos
• Quarter or test dime: always the same coin, in the same hand, for scale consistency
• Laser measurer: $40 Amazon unit gets you eave-to-ridge in 2 seconds
• Ridge anchor and harness: non-negotiable on 9/12 or steeper
• RoofKnockers Pro for photo auto-tagging, slope counting, and supplement drafting from inspection data

FAQ

How long should a multi-slope inspection take?

A 12-facet roof runs 45 to 75 minutes on a moderate pitch. If you are under 30 minutes on a cut-up roof, you are rushing and will miss slopes. Budget the time up front and quote accordingly.

What if the adjuster only walked 4 slopes?

Your full 12-slope photo set is the supplement. Submit the missing 8 slopes with the same test-square format the adjuster used on the 4 they walked, and request a re-inspection with a specific line-item dollar demand attached.

Do I need a drone?

For production hail work, a drone is optional but useful on 12/12 and steeper roofs. For commercial or multi-family, a drone is basically required. If you fly for commercial money, get a Part 107 license.
