We match membrane chemistry to your building’s operational needs:

EverGuard® TPO: The ultimate heat-welded “Cool Roof”; solution for energy efficiency.

Precision Engineering: Tapered Insulation Systems

Standing water is the #1 cause of roof failure. We solve "ponding" issues by using 3D modeling to design custom Tapered Polyiso slopes, ensuring positive drainage and 100% compliance with modern building codes.

Technical Insights for Property Owners

What is the advantage of a GAF Authorized Contractor?

Only 7% of roofers in North America are factory-authorized. Nabi can offer the Golden Pledge® Warranty, which is backed by GAF and covers both materials and labor, providing security that generalist contractors cannot match.

We address the root cause: heat loss. Our strategy includes attic air sealing, increasing insulation to R-49/R-60, and installing Ice & Water Shield barriers that extend 3 to 6 feet beyond the interior wall.

Under IECC 2024, commercial roofs in our region must reach a minimum of R-30ci. Nabi specializes in auditing existing structures and designing upgrades that meet these legal mandates.
