Who We Are

Great Lakes Roofing was founded in 1989 with a clear focus on commercial roofing. Every project, process, and system is built around the needs of commercial and institutional facilities.

Long-term client relationships are central to how we operate. Many clients return year after year for inspections, repairs, maintenance programs, and capital planning support.

Great Lakes Roofing has extensive experience working on complex and occupied buildings. Projects are planned to reduce disruption, protect interior operations, and maintain safe conditions for staff, tenants, and visitors.

More About Us

Commercial Roofing Services

Commercial Roof Replacement

Commercial roof replacement is appropriate when a roofing system has reached the end of its service life or when ongoing repairs no longer provide value. Great Lakes Roofing evaluates existing conditions, budget requirements, and operational needs before recommending replacement options.

This service applies to warehouses, manufacturing facilities, schools, healthcare buildings, retail centers, and other commercial properties.

Commercial Roof Restoration and Coatings

Roof restoration uses fluid-applied coatings or reinforcement systems to extend the service life of an existing roof. This option can reduce costs and limit tear-off when the underlying roof structure remains sound.

Restoration is commonly used on large commercial facilities, distribution centers, and industrial buildings where minimizing downtime is critical.

Commercial Roof Repairs and Emergency Service

Roof repairs address leaks, storm damage, flashing failures, and membrane issues. Emergency service is available when active leaks or weather events threaten interior operations.

This service is relevant for all commercial building types, including occupied office buildings, healthcare facilities, and retail properties.

Preventative Maintenance Programs

Preventative maintenance programs include scheduled inspections, minor repairs, and documentation designed to reduce unexpected failures. These programs help extend roof life and support budget planning.

Maintenance programs are ideal for multi-site owners, property managers, and institutional clients with long-term ownership goals.

Leak Investigation and Diagnostics

Not all leaks originate where water enters the building. Leak investigation uses moisture detection tools, visual inspections, and system analysis to identify root causes.

This service is valuable for facilities with recurring leaks, sensitive interior spaces, or complex roof assemblies.

Roof Inspections and Condition Assessments

Roof inspections provide a clear understanding of current roof condition. Assessments often include photos, system evaluation, and remaining service life estimates.

Inspections support insurance requirements, property transactions, and capital planning decisions.

Roof Asset Management and Long-Term Planning

Roof asset management helps owners plan repairs, restoration, or replacement across multiple years. This approach supports predictable budgeting and reduces emergency spending.

It is commonly used by portfolio owners, school districts, healthcare systems, and municipalities.

Rooftop Safety and Fall Protection Coordination

Great Lakes Roofing coordinates rooftop safety planning and fall protection measures as part of project execution. This includes safe access planning and compliance coordination.

This service supports facilities with frequent rooftop access or strict safety requirements.
