Big name. Neighborly by nature.
Mammoth was built in Boerne in 2017 to guide and protect our neighbors. That means an honest inspection, a written recommendation and care for the home behind the roof.
The Mammoth team at work
A Texas company. A neighbor’s promise.
The owner came to roofing after a decade of jobs that belonged to someone else's plan, and started Mammoth in 2017 with a simple rule: do what you say you're going to do. The first crews worked the Hill Country and north San Antonio; the office on IH-10 came next, then local teams north along I-35 and in Dallas–Fort Worth.
The process is written down and run on every roof: the free inspection, the Hunter-Gatherer Report, the written quote, the installation system and the 26-point QualCheck.

Roofing since 2017
Established in Boerne, serving Texas communities.
We do a lot of roofs. When one needs attention, we come back.
We are not going to tell you every Mammoth roof is perfect. We install hundreds of them a year across Texas, and a roof is thousands of parts installed by people on a hot day. What we can tell you is what happens when one of them needs attention: you call the office, a real person answers, someone comes out, and we handle it under the warranty we signed.
Hundreds of reviews across San Antonio, Austin, Temple, the Hill Country and Dallas–Fort Worth say the same thing in different words, and they are the reason we can make that promise: customers can find us, and they can hold us to it. That is what a local company with a real office is for.

Local teams serving five Texas markets.
One company, one written process, and a local number for every market. Not a franchise and not a storm-chasing outfit: every Mammoth office is company-owned, and the team in your market is accountable to the same standards as every other.
Market locations on a simplified outline of Texas, not service-area boundaries. Gold lines: the I-10 and I-35 corridors.
One company. One written process. Local teams where we serve.
About the company.
Ask your local teamAre you a local company?
Yes. Mammoth started in Boerne in 2017 and has local teams in San Antonio and the Hill Country, Austin and Round Rock, Temple and Central Texas, Kerrville and Marble Falls, and Dallas–Fort Worth. Every office is company-owned and accountable to the same standards: not a franchise, and not a storm-chasing outfit renting an address to look local.
Do you use your own crews?
Our crews wear the purple and run the same checklist on every roof. Every person on your roof is covered by workers' compensation.
Who inspects the finished roof?
A production manager runs the 26-point QualCheck with photos before the crew leaves, and you get the photo set.
Is the inspection really free?
Yes — it's the same Roof Grade visit for every service. Attic first, 75–150 photos, the 32-point Hunter-Gatherer Report, a letter grade and a plain-English verdict. You get the written report whether you hire us or not.
Will you tell me if I don't need the work?
Yes. An A grade is a handshake and a date to look again. A B means a few small repairs, priced in the open, on a roof with years left in it. We'd rather be the roofer you call in ten years than the one who sold you a roof you didn't need.
What is the Mammoth Boutique Experience?
The Mammoth Boutique Experience is high-touch, personalized roofing service designed to make homeowners feel taken care of at every step. It combines contractor expertise with the kind of attention, communication, and hospitality you would expect from a five-star experience. It matters on a home, and even more on a commercial roof, where the report is what the facilities manager and the owner see.
