Mammoth Contracting was born in Boerne, Texas, providing exterior home improvement services throughout the San Antonio Metro area. Mammoth’s mission is to change the roofing, siding, gutters, and exterior industry by setting the bar for what homeowners and real estate investors expect from a roofing contractor. 

We’ve had amazing success and have seen people really respond to our mission, and from there we started moving into other cities across the US. 

We are one of the fastest-growing national roofing companies because of our steadfast commitment to our customers and top-tier roofing services each and every time. Mammoth’s simple mission statement was designed to promote and reaffirm our commitment to our customers by reminding them what we do, and what our labor guarantee means. 

It’s a simple promise that encompasses everything we do and our “best in the industry” warranty. The Mammoth “Two Tusk” Lifetime Warranty is a limited lifetime warranty for materials and labor. We have a firm commitment to ethical business practices to lead by example in our industry. We are the leader in ethical roofing. Mammoth has you covered.
