About
Mammoth Contracting trades publicly as Mammoth Roofing & Solar and runs its headquarters from 26669 IH 10 West, Suite 1, with a Boerne postal address on the Interstate 10 corridor near Fair Oaks Ranch. The Better Business Bureau lists the business as starting in January 2017 and Scott P. Edwards as managing member, and the company's own site names Scott Edwards as founder. It has grown into a multi office operation with additional locations in Round Rock, Belton, Horseshoe Bay and Frisco, and it publishes separate numbers for San Antonio, Austin, Kerrville, Marble Falls and Temple. The service range spans residential roof repair, replacement and inspection, commercial roofing, rubber and urethane roof coatings, gutter installation, repair and cleaning, siding, solar panel installation, and storm and hail damage restoration. Materials include asphalt shingles, metal in aluminium, copper, corrugated, standing seam and steel, tile, and commercial systems in PVC, TPO, spray foam and modified bitumen. The company advertises a complimentary 37 point roof inspection and 50 year material with lifetime labour warranty language on its roofing systems. On verification, the Better Business Bureau shows Mammoth Contracting as accredited since March 2018 with an A+ rating. The company also states a CertainTeed SELECT ShingleMaster credential and Tile Roofing Industry Alliance certification, but neither could be confirmed on the manufacturer's or the alliance's own directory during this research, so both are recorded here as stated by the company. Texas does not issue a state roofing licence, a point the company itself makes on its site, so the trust basis is RCAT status, BBB accreditation and current insurance confirmed directly with the insurer.

Insurance & credential verification
Texas does not issue a state roofing license, so we verify companies the way homeowners actually can: confirming insurance coverage, checking RCAT (Roofing Contractors Association of Texas) status, and checking city or county registration where the local jurisdiction requires one. Every credential below links to the actual issuing organization's own public lookup — don't just take our checkmark for it. Always ask for a current certificate of insurance before signing any contract.
Confirm this licence yourself at web.rcat.net/rcat/search — search #03-0528 or the company name.
Confirm this yourself: ask the company for their certificate of insurance (COI). Note that RCAT's Licensed Roofing Contractor credential (CRRL, RRL or CRL) is earned and held by a named individual at a company, not by the business itself, which is why we name that person above where we know it; Texas issues no company roofing license at all. RCAT and NTRCA status can be checked in their own public directories (RCAT, NTRCA) — use the "Licensed"/"Accredited" filter to see more than plain membership. GAF's contractor verification tool and Owens Corning's Texas locator confirm those tiers directly; CertainTeed doesn't offer a comparable self-serve lookup, so ask to see that certificate in person. BBB accreditation and rating are on bbb.org. Houston's own published registered-roofer list is years out of date, so it isn't cited here at all — confirm registration by contacting the city directly. Corpus Christi's STAR program has its own online contractor registry — for any other city or county registration claim, confirm directly with that jurisdiction's permit office.

After filing our insurance claim we found Mammoth Roofing through Terrell. We met with Scott and he was straight to the point and he explained the difference between the quality of materials that they use. They did a great job working with the insurance company, they were quick and on top of it. Tim came out before the project started and answered all my questions and concerns and put some shingles on the roof so I could compare colors. We were really impressed that they were able to get started within a week and they finished in 1 day because they have a big crew. My roof no longer sounds like it’s about to blow off when it’s windy. I can’t barely even hear the wind now, where as before it was so loud. I also notice it’s not as hot as it was this time last year in our room. The shingles they use are way better than what we previously had and they look much better too. They gave us the best value for this project and we love the roof.
I had my roof recently replaced by mammoth, they did a great job. However I did have a concern about my siding after the roof replacement and Tim came out to check everything out and fixed my concerns. He went above and beyond. Every experience I’ve had with mammoth roofing has been positive. I’m happy we used them for our roof replacement.
Very pleased with our service! We bought a house with solar panels that apparently were not working properly. We called the company that installed the panels, multiple times, they never returned our calls. We called several other companies, same result. FINALLY we found Johnny Macias at Mammoth Roofing. He has been so helpful and knowledgeable, we are so grateful for his time effort. Highly recommend.
My husband and I had solar panels installed on our roof in 2020 by Nerd Power. They did a horrible job, and they left several holes in our roof. They told us that they were going to fix it and make it right, but they never did, and we're still dealing with the holes and leaks. We have had to work with several different roofers since then, and have paid so much money, even though we still have problems. With the rain last week, the roof started leaking again. I called Mammoth Roofing for an estimate. Tim Brady and Johnny Macias came out, and I can't say enough good things about them. They explained to us the extent of the damage, and they offered us two options. They said that they could do a quicker fix for $200 that would patch up the holes for 2 years, or they could do a much more intensive fix that would solve the problem for $10,000. My husband and I are retired senior citizens, and we don't have a lot of money. We can't afford the $10,000 plan right now, so we opted for the smaller option. Of all the roofers we've worked with and talked to in the last 6 years, they were the most honest, friendly, and professional. It rained again today, and no leaks! Thank you, Mammoth Roofing! We plan to call you in the future when we figure out how to pay for the bigger fix.
Tim stopped by and performed a thorough roof inspection at no charge. He confirmed our roof is in great condition, which gives us peace of mind after living in this house for 6 plus years.
