Our Comprehensive Flat Roof Installation and Repair Services

For over 25 years, we've been a reliable construction company that serves our clients' best interests. Our roofing experts provide these and other services in Greater St. Louis:


  • Installation: We will assess the size of your roof and install your chosen material. At Coldstream Exteriors, we make it a policy to use only premium roofing components from top manufacturers, and our knowledgeable technicians undergo thorough training on the most advanced application techniques. Our team will ensure your new flat roof installation is watertight and designed to fit your property's specific drainage needs.
  • Repair: If your current roof is in good shape with minor wear and tear, we can repair any damaged areas to restore their strength and appearance. First, our team will inspect your roof to determine the areas that need an upgrade, then we'll provide an estimate on the labor and materials needed to repair those sections.
  • Replacement: Has your current roof outlived its service life? Our inspection team can help you determine whether a simple repair or a complete replacement is the most effective option for your property's needs. The report will detail the true condition of your roof and recommend a solution that fits your budget. We have zero percent and low-interest financing available to make your project affordable.


No matter which service you choose, you'll be assigned a single project manager to communicate with throughout the process.

From the start of our engagement, Coldstream was responsive, knowledgeable and thorough. We had our roof replaced a few weeks ago and absolutely love it. Andrew took the time to drive us around and show us other roofs that they installed, which was super helpful for us in making our shingle selection. I highly recommend them!

Our experience with Coldstream was outstanding from beginning to end. They came out to do the roof inspection quickly, and provided us with photos of some problem areas. We received an estimate shortly thereafter, and the time lag between the time we accepted the bid and the initiation of work was shorter than I expected. The work crew was there on time the morning of the work day, and were incredibly efficient in getting the work done, even though some unanticipated damage needed to be corrected. We had no damage to the shrubs and trees near the house, and the clean up at the end was near perfect. Mario came out for the post-work inspection and answered all of our questions. Coldstream is first-rate, professional company that I would not hesitate to recommend to anyone. Five stars without hesitation.

Really enjoyed working with Ben Davis and his team. They were more than willing to listen to my specific roofing needs and recommend proper ways to address them. Their crew showed up at 7:30am each morning and worked until 8pm to get my roof completed in 2 days. And clean up was nothing short of excellent!! Highly recommend. Thank you Ben and team!
