Mammoth replaced our roof In October 2020. We had seen their work on a neighbor's house so we checked them out. Their online and BBB reviews were positive. From start to finish, they were very professional and responsive. Eddie Crowe assisted us in getting our insurance claim approved, including some supplemental items the original adjuster had not included.. He answered all our questions and then found a source for the Energy-star shingles we requested. The crew was amazing. They arrived early, wrapped our shrubs, and worked efficiently, which allowed for a one-day installation. They not only did a great job installing the new roof, but also in removing all the debris from our yard as well as our neighbors' yards. Finally, they quickly provided the supporting documentation for the insurance company which allowed us to receive the final claim payment within 3 days. We highly recommend Mammoth and Eddie. UPDATE April 2024: After a storm with high winds and heavy rain. we had a small leak around a vent flashing. Eddie and Tim responded the next day and quickly fixed the leak. Tim was very thorough in fixing the problem and did not rush the job. He also checked for anything that might become a problem later and resealed those areas. And Mammoth honored their lifetime warranty! Highly recommend Mammoth for any roofing jobs.

This company took the time of day to come out and help/work with me on my inconvenient schedule. They did a repair on a minor leak from a poor install from another roofing company and they identified/located the issue very swiftly and professionally.

Met with Scott to inspect my home after the big hail storm from last night which had about golf ball size hail. They inspected the roof and provided me pictures showing warning spots that may potentially lead to leaks in the future such as rusted nails that may expand but no immediate work was needed. Greatly appreciated the honesty provided by Scott and did not feel pressured at all to make any repairs. I will definitely work with mammoth in the future when repairs are needed and recommend to anyone needing roof repairs.

Timothy has been with Mammoth Roofing from its beginning, which is evidence of the excellent work environment provided by the company. Timothy is both professional and friendly and has a wonderful sense of humor. He did a fantastic job of repairing some rodent damage that led to leaking through the front wall during heavy rains. He sealed up all the cracks and spaces and covered them with metal to prevent any further damage. A very professional job. On a more personal note, Tim has led an interesting life. It turns out that he and my wife were both raised in Cleveland, Ohio, so they reminisced about places, people and food. And he did not charge me for the extra time. In fact, I think he undercharged me for the work. James R. Clark, MS, MPH

The G.R.O.O.V.E. Playbook: How Mammoth Builds High-Performing Reps

By Scott Edwards

This is not just a training manual—it’s a playbook for purpose-driven selling.

In Get in the GROOVE, Mammoth Roofing & Solar opens its doors to share the field-tested framework behind one of the most consistent appointment-setting systems in the industry. Built for new reps, seasoned closers, and even outside organizations looking to elevate their sales culture, this book breaks down the exact steps—from first knock to confident close—that turn conversations into trust, and trust into results.

Packed with real-world scripts, field breakdowns, and behind-the-scenes mindset philosophy, this book isn’t about hype—it’s about repeatable excellence.

Whether you’re joining our herd or leading your own, you’ll walk away with the structure, belief, and tools to build something that lasts.

About The Author

Founder. Builder. No Plan B.

For ten years, Scott worked jobs that looked stable on the surface—finance, insurance, corporate roles—but always felt like they belonged to someone else’s vision. He wasn’t building anything of his own, and the day-to-day offered little more than repetition.

After a personal and financial low point—including a Chapter 7 bankruptcy—he found himself starting over with almost nothing. A friend gave him a shot in roofing sales. Two small jobs in, someone wrote his commission on a napkin at a diner table. The number was more than he’d made in weeks. That’s when he saw what this industry could offer—not just income, but real ownership over your success.

From there, everything changed.

Scott built this company to give others the same shot he got. He doesn’t look for perfect résumés—he looks for people with drive, character, and something to prove. His goal is simple: train in weeks what took him a decade to learn, and create a path to success that’s real, not theoretical.

Today, he leads one of the fastest-growing roofing and solar teams in Texas—but he’s still walking jobs, coaching reps, and checking in with homeowners. Because no matter how big the company gets, the mission stays the same: do the job right, take care of your people, and never forget where you started.
