Boulder’s 1st Response Roofing

We offer a full line of roofing services, including repairs and new installations. However, we specialize in insurance claims. We go the extra mile to be certain that your insurance company pays every dime it owes you for the project. We ensure that they pay for all of the mandated upgrades and extras that they don’t often list in the first settlement they send to you. You have been paying your premiums for long enough, and we ensure that you receive what you are due for those payments. We deal directly with your insurance providers to minimize your time and efforts, and maximize results. Check our reviews. We are second to none when it comes to negotiating with insurance companies.

We also specialize in repairing areas that were built with design flaws. On several occasions, we have been able to completely stop leaks that have already been “repaired” by the other guys multiple times. When we complete a project, you can rest assured that the project will be completed correctly the first time.

Quality 5 stars out of 5

Marc is perhaps one of the top tradesmen I have ever seen work. He shows up when promises and puts quality above profit. He will not settle for second best. In this day, and especially with the reputation of fly-by-night roofing companies, it was a PLEASURE to watch him work. His attention to detail is unsurpassed. I STRONGLY recommend him to all!

Excellent job

5 stars out of 5

Marc and Mark did an excellent job. Very happy with the process, quality of work, attention to details, and patience with my many questions. It was very helpful to have Mark explain details to the insurance company to maximize the insurance payment. Fantastic clean up every day and after the job was complete. If quality is important to you, hire 1st Response Roofing. There’s no better.

As a home builder, I have used a number of different local roofing companies. 1st Response Roofing stands out above the others out there by providing excellent workmanship, and a true attention to detail. 1st Response always provides fair pricing, and trustworthy service. I will continue to use 1st Response as my roofer of choice.

Owner Marc Mosello did excellent, detailed work at my residence in Table Mesa last Spring. From the bid to tear off to final installation, Marc was meticulous and professional throughout the process. I highly recommend 1st Response Roofing and I know Mr. Mosello will do outstanding work for you.

Marc Mosello recently completed our roof, and did so in a timely manner. He was willing to help us out before, during, and after with many associated issues that came up as we rehabilitated our new home (a foreclosure). He is knowledgable, thorough, and showed incredible attention to detail. Furthermore, his cleanup went above and beyond what I expected. I would highly recommend Marc to do any roofing project.

The contractors who work on my projects need to be highly skilled craftsmen who take pride in their work and consistently do what they say they will. Marc has now done several roofs for me and I have been impressed with the quality of his work every time. The roofing industry is absolutely riddled with contractors cutting corners, because homeowners don’t know the difference. Marc not only didn’t cut corners he devoted attention to creating exceptional flashing details and being meticulous about every aspect of the installation. This combined with his selection of superior products makes his work stand clearly above the other roofing contractors I’ve used.
