Red Diamond had positive reviews to begin with and did not disappoint. Quality installation of roof and gutters. The sales rep Ed Duffy was friendly, very responsive, sensitive to our needs and went out of his way to get any remaining issues worked out after the installation. Ed was happy to source the shingle manufacturer we had previously installed. Invoicing was straightforward and without issues. I would highly recommend Red Diamond Roofing.

I decided to go with Red Diamond roofing based on a referral from my Realtor. I couldn't be happier with the results. My roof was in really bad shape after years of neglect (from the previous owner) and hail damage. Matt, the project manager, came out to my house and met with the claims adjuster to address my concerns. He even worked with me to have a few improvements installed, namely drip edge for the trim and a ridge vent to improve air circulation underneath the roof. His crew had the roof stripped and re-installed in a day. They even managed to replace some of the plywood decking that had rotted.

Review by in Longmont, CO
We had the pleasure of working with Red Diamond Roofing and specifically our project manager, Tyler Calomino, after last summer's hail storm which left our roof significantly damaged. Tyler walked us through every step of the process, and in every way, was a true professional. After coming out to do an initial evaluation of our roof, he noticed that the peak above our sunroom was vulnerable to more water damage, so he did a short term repair on the spot! Additionally, he came out during the insurance inspection to be sure that the evaluator was made aware of all of the damage. As a result, damage was noted that we were even unaware of, the gutters for instance, which were replaced along with the roof. Tyler was the perfect intermediary between our insurance company and Red Diamond Roofing. He made sure that funds were accurate and that the correct payments were made. It couldn't have been easier. We were updated frequently throughout the whole process and couldn't be happier with the end result! My only complaint is that they only work on roofs because our experience was so positive that I'd like to turn to Tyler and Red Diamond Roofing for all of our home repair and renovation needs. I couldn't recommend them more highly!

Review by in Denver, CO
When hail wrecked Wheat Ridge in May 2017, I was left needing new roofs for my house and garage plus needing new gutters and gutter guards on both structures. After reading some reviews online and seeing a few of Red Diamonds signs in my neighborhood, I deiced to contact them. BIG MISTAKE. Michelle from Red Diamond was assigned to my claim and she was extremely difficult to work with. She contacts at very odd hours of the day, was unable to provide any billing statements when asked over several separate occasions, and never kept her word as to when work would be started on the roof, gutters or gutter guards. The gutter guard install was especially odd. At first, flimsy black plastic guards were installed by Red Diamond even though I had black power coated aluminum ones originally on my house and garage. I bought that up to Michelle and asked that metal guards be installed and she said that I did not have metal gutter guards on my house or garage! I have my own photos and photos from State Farm proofing I had metal gutter guards installed! She then said it was too expensive to replace with metal guards, and TRIED TO BRIBE WITH ME $100 TO DROP THE ISSUE!!!! I've kept all the texts to show other people! I said NO and put my foot down on the issue. Red Diamond finally gave in and put up UNCOATED aluminum gutter guards. The install of the guards is extremely shabby and I'll have to go up myself and square them up. The only reason I gave Red Diamond 2 stars was because the roof passed inspection. The company was hard to work with, never keeps schedule, does sloppy work. AVOID RED DIAMOND AT ALL COSTS!

Last year's hail storm ruined my roof, but Red Diamond came to the rescue. They were on time to every appointment, very communicative, took care of all the insurance negotiations, and the quality of the roof itself is impeccable. Needing a new roof is a pain, but they made it as painless as possible. Thank you Brian and your team for the great work!

Brian was very helpful and knowledgeable Gave a quote, and his material was delivered 1 week later. The job was finished the next day. Premises cleaned up afterwords. Looks Great. I will be reviewing this company on yelp as well. I Highly recommend this Company. I would like to add a footnote...I Got this company off Home Advisor List, however since They did not refer me to this company I do not get credit for using one of their contractors. Not sure why they have a list, or how they determine which contractor to set you up with, but I will not use Home Advisor in the future. I advised Red Diamond Of this, so they could determine if they want to use Home advisor in the future.

Mark Lewis was a wonderful Project Manager. He turned a stressful situation into a quick and manageable project. The roof crew was efficient and installed the roof correctly the first time. They cleaned up our property thoroughly at the end of the job. Overall, I was very pleased with Red Diamond Roofing and will definitely recommend them to friends.

Project: Install or Replace an Asphalt Shingle Roof
Red Diamond and Mark Lewis our project manager did a great job under a lot of pressure to get the job done in time for our house to close. The roof looked great and they stayed on budget. Great company and they take pride in thier work.

After a recent hail storm, my neighbor recommended Red Diamond Roofing. This was my first time dealing with a major home repair and project manager Mark L. made it painless. Mark first walked me through the timeline, helped me navigate the insurance company and even made a recommendation to a separate HVAC team for the installation of bathroom vents. The installation team was prompt, efficient and the roof looks great. Mark came back and walked our yard to make sure that clean up was done to Red Diamond specifications. Give them a call.

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
