We design and install commercial roofing systems that prevent leaks, protect the building envelope, and deliver dependable performance throughout the roof's life.
A commercial roof is one of the most critical components of a building’s exterior. When it fails, the consequences extend far beyond the roof itself, affecting interiors, operations, and long-term asset value.
At Nastase Commercial Exteriors, we approach commercial roofing as a performance system, not just a surface. Every roof we install is designed to manage water, withstand Midwest conditions, and integrate cleanly with the rest of the exterior so the building stays watertight year after year.
We work with general contractors, developers, property owners, and managers across the full lifecycle of commercial properties.
For new construction, we collaborate during preconstruction to confirm roof assemblies, details, and sequencing so the system performs as designed and installs efficiently.
For existing buildings, we assess roof condition, identify risk areas, and help plan repairs or replacement based on remaining service life and budget priorities.
Our focus is always the same: reduce leaks, extend roof life, and eliminate surprises.
Our commercial roofing services include both low-slope and architectural systems, selected based on building type, performance requirements, and long-term value.
Each system is installed with careful attention to transitions, penetrations, and tie-ins so water stays where it belongs.
A roof’s true cost is measured over decades, not just at installation. We help clients make informed decisions by considering:
When appropriate, we also connect roofing projects with ongoing maintenance and exterior assessments to help extend roof life and catch issues early.
Our No Surprises Guarantee means clear scope, transparent pricing, and the exact roofing system specified. No hidden costs, no substitutions, and no last-minute changes.
We evaluate the building, review goals, and develop a roofing plan focused on watertight performance and longevity.
Certified crews install the system with attention to detail, sequencing, and site protection.
Your roof is documented, watertight, and built to perform, giving you confidence in the years ahead.
