Andrew Mussio knew there was “a lot left on the table” when he joined WeatherPro Exteriors as the VP of Marketing and Innovation. The Milwaukee-based company had been a staple in the market since 2008 — but its operations were frozen in that era.
File cabinets were stuffed with printed job records. There were mazes of Excel spreadsheets. Their roofing CRM was not fully integrated, which led to a culture of uncertainty.
“If you're tracking something outside of your core platform, you really lose that confidence from the team of whether this is accurate,” Mussio said on the Roofers Coffee Shop podcast.
When numbers didn't match across different tools, accountability vanished. Mussio said it was common to hear, “Those aren’t my numbers,” or “That’s not correct.” Having previously experienced the power of ServiceTitan in the garage door industry at A1 Garage Door Service, Mussio knew exactly what was missing.
He didn't just want a new tool or to go paperless; he wanted a company shift that would shed light on every corner of the business.
Transparency Through Data
Mussio said the transition to ServiceTitan was about turning every employee into a data collector.
By equipping field reps and installers with tablets, WeatherPro was able to require forms and photos at the end of every job. This ensured that critical job details were captured in real-time, leaving no room for guesswork.
That data, paired with ServiceTitan’s dispatch board, is what gave the WeatherPro team visibility like never before.
“Having that visual on the dispatch board... you can pull out the map and see where all of our people are in (real) time. It is extremely, extremely powerful,” Mussio said. This live tracking meant CSRs could give customers exact updates, transforming the customer experience from “I think he's close” to “He's five minutes away.”
But the real game-changer was the integrated call metrics. ServiceTitan enabled WeatherPro to record and classify every call.
This data revealed hidden growth opportunities:
Market Intelligence: Identifying services customers were asking for that the company didn't yet offer.
Marketing Accuracy: Correcting misleading ads that were driving the wrong types of calls.
Coaching: Listening to recordings to improve CSR and sales performance.
“(ServiceTitan) has shed so much daylight in the business,” Mussio said. “It’s remarkable.”

The Maturity of Processes
Change management is never easy, and Mussio’s strategy involved identifying the biggest advocates to lead the charge while spending extra time with those who were hesitant.
The results of that effort are clear. Since implementing ServiceTitan, WeatherPro Exteriors has grown by 35%. That growth gave them the stability to open an entirely new market.
However, Mussio argues that the most significant result isn't just the revenue — it’s the “maturity of our processes.” Instead of making decisions based on feel, they make them on KPIs.
“The whole culture has shifted,” Mussio said. “And it’s amazing to see.”
For other roofing contractors on the fence, Mussio suggests looking at the community.
“The top home service companies have been using ServiceTitan and have developed all these great tools that we can take advantage of — from day one.”
