Comprehensive Commercial Roofing Solutions

Our skilled commercial roofers specialize in installing a wide range of commercial roofing systems, including:

  • Built-up Roofing (BUR): This traditional hot-tar-and-gravel system provides excellent waterproofing and durability for low-slope roofs.
  • Single-ply Membranes: TPO, PVC, and EPDM single-ply membranes offer flexibility, energy efficiency, and resistance to UV rays and chemical exposure.
  • Modified Bitumen: A modern alternative to BUR, modified bitumen systems feature a resilient, rolled asphalt-based material for reliable performance.
  • Metal Roofing: Lightweight, fire-resistant, and energy-efficient, metal roofs provide long-term value and protection for commercial buildings.

Our team works closely with you to assess your building’s specific requirements and recommend the optimal roofing solution for your budget and performance goals.

Customer Reviews

Chris and his team were fantastic to work with. He was super responsive and immediately got back to me, fitting me in for the next day. Todd came by and explained what he was seeing and presented me with options for my new roof.

Caitlyn P

A huge shout out to C.M.L Roofing & General Contracting. Chris (owner) came out on a Monday to evaluate a leak around the flashing in the roof. Wednesday he and one of his employees returned and happy to report leak fixed.

Linda H.

CML roofing provided a great experience from beginning to end. Prompt and professional. We got a quote, and had our roof done a week later. Very pleased with the turnout and transparency along the way. Highly recommend CML to anyone looking for quality work.

Ashley H.

Good solid roofing, did an epdm roof for us. Responsive communication and accurate pricing. Leo is a great PM and a great hype man helps you feel comfortable about your project.

Dainius B.

I highly recommend CML Roofing if you are looking for any roof work. Colin took the time to meet me onsite and thoroughly explain the process which allowed me to make an informed decision about what was needed.

Anne O.

Great to work with. Professional, careful, and clean. Their crew went above and beyond on our roofing project and there were no surprise add-ons from our initial quote. Highly recommend!

Jake M.

We couldn’t have asked for a better experience. Our home continued to experience wind damage to a roof that wasn’t any more then 10 years old. Chris and his crews came out multiple times to help patch up missing shingles until we finally decided it was time to just replace the roof.

Eric S.

The CML team did an outstanding job!! Chris’s knowledge and experience make it an easy decision of who to have put a roof on. His team is professional, on time and get the job done. Not only did the team fix my roof that had shingles falling.
