Quick AnswerMost commercial roof replacements in Colorado run between a low and high range per square foot depending on the system you choose, the size and slope of the building, and how much tear-off and deck repair is needed. Single-ply membranes like EPDM sit at the affordable end, while TPO sits at the premium end. The honest answer is that price follows the building, not a flat rate, so the only accurate number comes from a real inspection. |
Commercial roofing is priced per square (100 square feet) or per square foot of installed roof, and the range is wide because the systems are so different. A simple single-ply membrane on a flat warehouse is a different animal than a standing seam metal roof on a retail center. The building, the existing conditions, and the system you pick set the number.
Use the ranges below as planning brackets, then get a measured proposal. These are typical installed ranges for our market and should be confirmed against your specific building.

After 30-plus years on Colorado roofs, we can tell you the system is only half the cost. The rest is the building. The factors that move your number the most are tear-off, deck condition, insulation, and access.
Sometimes, yes. If a building is changing hands soon or has a short remaining use, a basic single-ply can be the smart financial call. But in our climate, the cheapest bid is often the one that fails first. Intense UV at altitude, and big temperature swings punish thin materials and shortcut installs. I would rather price you a roof that lasts than win a job with a number that costs you twice.
That is why we say you do not pay a cent until you are content. We would rather earn the work by being straight with you about what your building actually needs.
It depends on the system and the building, but single-ply membranes sit at the lower end of the per square foot range and standing seam metal at the higher end. Tear-off, deck repair, and insulation upgrades move the final number more than most owners expect, so a measured proposal is the only accurate figure.
Quotes vary because contractors scope the work differently. One bid may skip needed deck repair or use a thinner membrane to come in low. They may skip building a taper system, appropriate components, necessary to the NDL from the manufacturer. Some systems will come with a NDL warranty, this is very important, others may not. Always compare the system, the membrane thickness, the warranty, and exactly what is included before you compare price.
Yes. In Colorado's hail belt, paying for an impact-resistant system and proper installation usually saves money over the life of the roof by reducing storm repairs and premature failure. Most flat roofing membranes are very resistant to hail, because they are malleable.
If the roof was damaged by a covered event like hail or wind, often yes. The payout depends on your policy, whether you carry replacement cost value or actual cash value, and a proper damage assessment. We can document storm damage for your claim.
