Flat roofs that stay dry and on budget.
Replacement, repair, and restoration coatings for TPO, EPDM, modified bitumen, and metal roofs. We have serviced some of the same Denver commercial buildings since the 1970s.
Fifty years on the same commercial roofs.
Gen 3's roots are commercial. Our founders first roofed commercial properties in the Denver area in 1968, and we still maintain and re-roof some of the buildings we worked on in the early 1970s. That continuity means we know how each membrane system ages on the Front Range, and what it takes to get another decade out of one.
We replace and repair TPO, EPDM, modified bitumen, and metal panel roofs, with full tear-off to the deck so the structure can be inspected. Where the membrane is sound but tired, a silicone, acrylic, or elastomeric coating can add 10 to 15 years at a fraction of replacement cost and improve energy efficiency.
Every commercial project gets a detailed scope of work before anything starts, scheduling around your tenants or operations, and a single point of contact. Property managers can ask about service agreements covering multiple buildings.

Commercial Flat Roofing & Coatings questions
If the membrane is dry, adhered, and under about 20 years old, a coating often makes sense and buys 10 to 15 years. If the insulation is wet or the seams are failing across the roof, replacement is the honest answer. A core sample tells us which.
TPO is the most common choice for reflectivity and cost; EPDM handles freeze-thaw and hail well; modified bitumen suits roofs with heavy foot traffic. We recommend by building, not by habit.
Yes. Hail and wind uplift claims on commercial roofs are a regular part of our work. We document, meet the adjuster, and restore to pre-loss condition.
Yes. We schedule around business hours, tenants, and loading docks, and we stage materials by crane where that keeps the site clear.
