Which roofing software APIs let you build missing integrations?

Some roofing vendors publish developer documentation anyone can read. Others publish a partnership form. The difference decides whether the connection you need is work you can commission or a request you can only file.

Four roofing vendors, EagleView, Hover, AccuLynx and GAF QuickMeasure, each with a padlock and four access stages: docs, credentials, production and purpose-built. EagleView fills the first three, Hover the first two, AccuLynx has docs and purpose-built, and GAF QuickMeasure has none.

EagleView, Hover and AccuLynx all publish developer documentation, so a contractor can commission a missing integration against any of the three. GAF QuickMeasure publishes none, so you can only wait for a partnership. That difference decides who you have to ask, and almost nobody asks it during a sales call: if the connection I need does not exist, can I have it built?

The answer comes down to whether the vendor publishes developer documentation, and the category splits three ways.

Who publishes real developer documentation?

EagleView. Its developer portal documents a REST API for measurement reports. The Measurement Orders documentation describes an automated way to place and retrieve detailed property measurement reports covering roofs, walls, windows and doors without ordering through the web portal, and says results can be retrieved as downloadable files in PDF, XML, JSON, DXF or JPG, or directly from the API response. Order placement, status tracking and webhooks are all documented. The page was last updated in 2025 and rechecked in July 2026.

There is a gate worth planning around. Sandbox credentials are self-generated at no charge. Production credentials, per EagleView's own get-started documentation, are not activated until a request to go live is approved, after a review where an administrator may ask clarifying questions or request a demo of the integration. EagleView's marketing page describes generating credentials without needing additional support and does not mention that step, so work from the documentation.

Hover. Its developer documentation describes an API that programmatically creates and manages jobs, initiates property captures, retrieves 3D models and measurement data in JSON, PDF, XLSX, SKP, ESX and XML, sends real-time status updates by webhook, and manages organisational resources. Access is self-serve for an existing customer's team admin.

One research trap: hover.com is a domain registrar owned by a different company entirely. The roofing measurement vendor is hover.to. Check the ending before you follow a link.

AccuLynx. Publishes API documentation and states you need an active AccuLynx account and an API key you create and name yourself. Its own guidance says the audience is experienced developers or people with strong subject matter knowledge, and points software businesses seeking a listed marketplace integration at a partnership application instead.

Who does not?

GAF QuickMeasure, and the way to say this matters.

GAF publishes no developer or API documentation for QuickMeasure. Its ordering system is a web application offering Place Order, Track Order, Redeem Code, Coverage Map, Sample Report and Support. The GAF QuickMeasure page says reports can also be accessed from other platforms, pointing at partner software rather than at an API.

What that does not mean is that QuickMeasure has no machine interface. AccuLynx and ServiceTitan both document ordering QuickMeasure reports from inside their own products, so something clearly passes between GAF and its partners. The defensible statement is about publication, not capability: GAF does not publish developer documentation, so a contractor cannot build against it the way they can against EagleView or Hover.

There is a related trap in the QuickMeasure comparison material, which lists an XML data file among the report deliverables. That is a file in the report package. It is not an API response, and it should not be read as one.

Why does API access decide more than it looks like?

Because it changes who you have to ask.

When a vendor publishes documentation, a missing connection becomes ordinary engineering. Any competent developer can read the docs, build the thing, and hand it over. You commission it, you own it, and it exists on your timetable.

When nothing is published, the same missing connection becomes a request. You file it, it joins a queue, and it competes with every other customer's request against a roadmap you cannot see. It may arrive. It may not. You will not be told which.

That is the whole difference, and it has nothing to do with how good either product is.

If the connection you need does not exist Published API No published API
Who can build it Any competent developer Only the vendor
Whose schedule it runs on Yours Theirs
What it costs to find out if it is possible Reading the docs A sales conversation
What happens if they deprioritise it Nothing, you built it It does not happen
Who owns it afterwards You Them
What happens if the partnership ends You still hold the code The connection goes

What should you ask a vendor before you buy?

Ask for the developer documentation URL during evaluation, not after.

It is a fast question and the answer is revealing in both directions. A vendor who sends a link in a minute has one, and the fact that it is public means it has to stay stable, because other people depend on it. A vendor who offers to "connect you with the partnerships team" has told you the real answer without saying it.

Neither response should disqualify anyone on its own. Plenty of good software has a closed surface, and an open API is not worth much if the product underneath it is wrong for you. What the answer gives you is an accurate picture of what happens later, when your process changes and the software has to change with it.

That is the practical half of the argument we made in own your software instead of renting it, and it is why the buying questions in what to ask before you sign spend more time on structure than on features. Features are what a product does today. This is what it can be made to do next year.

Frequently asked questions

Does EagleView have an API?

Yes. EagleView publishes a developer portal documenting a REST API for measurement reports, with order placement, status tracking and webhooks. Results come back as downloadable files in PDF, XML, JSON, DXF or JPG, or directly from the API response.

Does Hover have an API?

Yes. Hover publishes developer documentation describing an API that creates and manages jobs, initiates property captures, retrieves 3D models and measurement data in JSON, PDF, XLSX, SKP, ESX and XML, and sends status updates by webhook. Note the domain is hover.to, not hover.com, which is a different company.

Does GAF QuickMeasure have an API?

GAF publishes no developer or API documentation for QuickMeasure. Partner integrations clearly exist, since AccuLynx and ServiceTitan both document ordering reports in-app, so some machine interface exists. What you cannot do is build against it yourself, because nothing is published.

Can I build against AccuLynx?

Yes, if you are a customer. AccuLynx publishes API documentation and states you need an active account and an API key you create and name yourself. It is aimed at experienced developers. Software businesses wanting a listed integration are pointed at a partnership application instead.

Why does an open API matter to a roofing contractor?

Because it decides what you can do when a connection you need does not exist. With published documentation, it is work you can commission from any competent developer. Without it, the only route is asking the vendor and waiting.

Is there a catch with EagleView's API access?

Yes, and it is worth planning for. Sandbox credentials are self-generated at no charge, but production credentials are not activated until a request to go live is approved, and an administrator may ask clarifying questions or request a demo of the integration.
