First, I have to admit, initially, I wasn't sure about this company. I wasn't really feeling their initial 6pm knock on the door visit. However, upon request they came back and went over their plan with me. I did some research on the company and saw other jobs they did in my neighborhood, and the cleanliness and professionalism of the workers had me sold. OPINION AFTER THE FACT. There were no surprise expenses. only thing I had to take in account, that they couldn't tell me ahead of time, was whether or not there were damage to plywood under the tile. There was 3 â 4 damaged pieces, but the money that the insurance gave me covered it all. My salesman was Oscar, and I have to give him a big Thumbs Up because I wasn't really that friendly during the initial meeting, was a little shock to come home at 6pm to find them sitting at my dining room table, not their fault. But not a good day. He maintained his professionalism, and patience and won my confidence. Two story home, completed in one day, company personnel kept in contact informing me about drop off, start time, cost, insurance payments. The warranty was received approximately 1 week after completion. I would recommend this company to my friends.

We had a total roof replacement due to a hail storm. Customer service and responsiveness were great from top of company, Scott Edwards, to Jordan Leal who managed the project. To me the real test is when an issue arises and Mammoth shined. We had an issue and it was quickly and professionally resolved. I do recommend Mammoth Contracting.

After a heavy hail storm, I hired Mammoth Contracting to replace my roof. Project manager Darrell Barker went above and beyond to help me with choosing roof material, colors, and explained product details and warranty. Mammoth roofers were punctual and completed the job with no issues. I appreciated the cleanup after as well. I couldn t find a single piece of trash or nail.

We were very impressed with Mammoth Contracting. We were especially appreciative that Zachary Cisneros called/and was also there in the dealings with the Insurance Company and the Adjuster. He was courteous, able to answer questions/or able to get the information quickly. Zachary, Scott & Tim displayed the highest professionalism. The day the roof was put on went relatively smoothly and was accomplished in one day. We were able to get a discount on our insurance because of the quality roofing shingles that were used. Best of all â we have a beautiful new roof that should last for many years and that we feel very good about every time we look at it. Zachary & Mammoth Contracting are tops in our book.

Mammoth roofing is a company that will always have my business. Kaleb, my sales representative, when extremely professional and courteous when going over my initial roof inspection. Along with answering my many questions, the overall feel of having someone you can trust working on something that protects you and your family is exactly what this company offers. I highly recommend this company, as well as their wonderful sales representatives.

We sustained roof damage from hail in 2019 just a few weeks after closing on our first home. As a first time home owner it can be intimidating to embark on an insurance claim for the first time, but Jordan was able to clearly explain each step of the process from initial visit to final payment and warranty information. I would highly recommend Mammoth Contracting if you are in need of home contracting services. Thanks for the help!
