Measure roofs free. No report to order.
Contractors pay for EagleView reports and Hover scans one roof at a time. In Crewtavo, measuring is part of the free software: outline the roof on the aerial, read the pitch from free USGS lidar or your phone, and get squares, drip edge and ridge cap, a roof report, and a Good, Better, Best estimate priced from your own list.
- Eaves 104 ft
- Rakes 71.6 ft 64 ft from above
- Ridges 52 ft
- Drip edge 175.6 ft
- Ridge cap 52 ft
From an address to a signed roof proposal.
Measure it yourself in a few minutes, on the same screen you price it from. Nothing to order and nothing to wait for.
Step by step: Get a roof estimate out from the aerial
- 1 Outline the roof Open Roofing, pick the client and the address. Where the map has the building, its outline is already drawn: drag the corners out to the drip edge, or draw the roof yourself.
- 2 Set the pitch Read it free from USGS lidar, lay your phone on the shingles, or measure it from a photo of the gable. A porch or dormer can have its own pitch.
- 3 Mark the edges Pick eaves, rakes, ridges, hips or valleys and draw along them. Rakes, hips and valleys are stretched by the pitch, since they run up the roof.
- 4 Save the roof report Squares with waste, each section at its pitch and the feet of every edge, on the aerial with a scale bar and a north arrow.
- 5 Price it and send it Offer one roof or Good, Better and Best, add tear-off, drip edge and ridge cap from your price list, and send a proposal the homeowner signs online.
Three free ways to get the pitch. Only one of them needs a ladder.
-
From USGS lidar
The US Geological Survey has flown laser scans over most of the US and gives them away. Crewtavo downloads just the part over the roof and reads each plane’s pitch, usually in under 10 seconds.
-
With your phone
Lay the phone flat on the shingles and it reads the slope from its tilt sensor. Wait for Steady, then use the pitch it shows.
-
From a photo
Take a picture straight at a gable end, then drag one line along the roof edge and one along the gutter. Good for a quick check from the ground.
Crewtavo vs. paid roof reports. EagleView and Hover measure the roof for you, for a fee each time. Crewtavo has you measure it on free imagery.
| Topic | Crewtavo | EagleView | Hover |
|---|---|---|---|
| What it costs | Free, part of Crewtavo | Paid per report, less with volume | Paid per project, or a yearly plan that lowers the price per project |
| Who measures the roof | You, on the aerial, in a few minutes | EagleView, from its own aerial photos | Hover, from photos taken at the house with a phone |
| Imagery | Free US imagery, about 1 to 2 ft a pixel, or Esri or Google with your own key | Its own straight-down and angled aerial photos, far sharper | No aerial: a guided phone scan of the house |
| Pitch | Free USGS lidar, your phone, or a photo of the gable | Measured for every roof facet | Measured from the 3D model |
| Waiting | None: measure it while the homeowner is on the phone | Delivered in hours, after you order | Delivered in hours, after someone scans the house |
| Walls, siding and windows | Roofs only (lawns, lots and driveways too) | Separate wall and full-house reports | Yes, with a full exterior project |
| Insurance claims | No Xactimate files | Xactimate files, and reports adjusters order | Xactimate files among its exports |
| Into your estimate | Squares and edges price your own list on the spot | A report you price from, or an integration | A report or export you price from, or an integration |

From the roof to the estimate. The report isn’t a file you retype: every number on it prices the job.
-
A roof report
The roof on the aerial with each kind of edge in its own color, a scale bar, a north arrow, your business, the address and the date. Put it on the proposal.
-
Good, Better and Best
Tick two or three roofs, like architectural shingle or standing-seam metal. The homeowner picks one on the proposal and the total follows.
-
Every section at its pitch
A porch or dormer gets its own pitch, and the squares add up each section at its own. A steep roof charge prices sections at 8/12 and up.
-
Edges into materials
Drip edge from the eaves and rakes, ridge cap from the ridges and hips, valley flashing from the valleys, each priced from your list.
-
Your own price list
Formulas read squares, squares without waste for tear-off, steep squares and each edge. A roofing price book adds the usual services to start from.
-
Then the job
Once it’s signed, the estimate becomes the job: schedule it on a crew’s day, take a deposit, and invoice it when it’s done.
Is Crewtavo right for you? An honest take.
Free measuring is a great fit if
- You measure plenty of roofs that never sell, and report fees add up
- You want a price while the homeowner is still on the phone
- Your roofs are mostly gables, hips and a porch or two
- You want the measurement to price the estimate, not sit in a PDF
A paid report may suit you better if
- You need Xactimate files or reports an insurance adjuster expects
- You want walls, siding and windows measured too
- You’d rather not draw the roof yourself, or it’s cut up into many facets
- You want sharper imagery, or a measurement its maker guarantees
Roof measuring FAQ.
Is the roof measuring really free?
Yes. Measuring is part of Crewtavo, which is free for any size of business, and the imagery and lidar it uses are free too. There’s no fee per roof or per report. Crewtavo runs in your own Railway account, and you pay Railway directly: its Hobby plan is $5 a month and includes $5 of usage.
How accurate is it?
As accurate as the imagery and your outline. The free US imagery is about 1 ft a pixel where a state publishes its own and about 2 ft elsewhere, so drag the outline to the drip edge and check anything that changes the price on site. Lidar reads the pitch to about half an inch per foot, but it may be from before a reroof or an addition: the survey’s year is shown with the result. Paid reports use much sharper imagery, and some guarantee their numbers.
Where does the pitch come from?
Your choice of three. Lidar from the US Geological Survey covers most of the US, and Crewtavo reads each roof plane’s pitch from it. Or lay your phone on the shingles and it reads the slope from its tilt sensor, or measure it from a photo of a gable end. You can always pick a pitch yourself.
Does it work outside the US?
The free imagery and lidar are for the US. Elsewhere, add a free Esri key or a Google key for imagery, and measure the pitch with your phone or a photo.
Can I replace EagleView or Hover with it?
For bidding most retail roofs, yes: you get squares, pitch, edges, waste and a priced proposal without ordering a report. Keep a paid report for insurance claims that need Xactimate files, for walls and siding, and for complicated roofs you’d rather not draw yourself.
Can I use the roof measuring without the rest of Crewtavo?
Measuring is part of Crewtavo, so you set Crewtavo up to use it, in your own Railway account in a few minutes. Use as much of the rest as you like: many roofers start with estimates and proposals, then move scheduling and invoicing over later.
Is Crewtavo affiliated with EagleView or Hover?
No. Crewtavo is an independent open-source project. EagleView and Hover are trademarks of their owners, used here only to describe the comparison.
