Commercial Roofing
& Waterproofing Contractor

How We Deliver

One Contractor. Every Layer.

Commercial roofing and waterproofing projects typically move through several distinct phases. Understanding those phases helps owners know where a project stands, what decisions need to be made, and what type of expertise may be needed along the way.

  • Assess & Diagnose — Inspect existing conditions, identify the problem, determine its source, and understand the building owner’s needs.
  • Plan & Design — Evaluate system options and determine whether engineering, consulting, or formal design is required before the scope is finalized.
  • Build & Restore — Carry out the work through replacement, restoration, repair, retrofit, or phased construction based on the project requirements.
  • Repair & Maintain — Protect the completed system through ongoing maintenance, repairs, warranty-related care, and response to developing or urgent conditions.

Contractors, consultants, engineers, and other project professionals may enter the process at different points depending on what has already been completed and the owner’s existing relationships. A project may already have plans and specifications in place, or it may still require assessment, engineering, consulting, or design support before construction begins.

Wherever a project is in the process, the next decision depends on understanding what has already been established, what still needs to be resolved, and what the owner or project team needs next. An assessment, scope review, pricing discussion, or design conversation can help clarify the available options and the best path forward. That first conversation should be simple, straightforward, and free.

Why Strong Contractors

From Assessment to Maintenance: A Lifecycle Approach

Strong Contractors is focused exclusively on commercial roofing and waterproofing, with no residential roofing division. More than a decade of experience across commercial roof systems and waterproofing applications gives our team the knowledge to look beyond a single product or solution and understand the options available throughout the life of a roof.

Owners, engineers, and consultants can involve Strong from assessment and planning through construction, restoration, repair, and maintenance—keeping our expertise connected to the project from start to finish.

Assess & Diagnose

Diagnostic Assessment and Substrate Analysis

A commercial roof assessment starts with understanding the visible conditions, known problem areas, previous repairs, drainage, penetrations, transitions, and how the roof is currently performing. In many cases, an experienced roof walk and documentation are enough to identify the next step.

When conditions are less clear or the project requires deeper investigation, additional diagnostics may include:

  • Infrared moisture scanning — helps identify areas that may contain trapped moisture within the roof assembly.
  • Core sampling — confirms the existing roof assembly and allows direct inspection of insulation and underlying materials.
  • Moisture verification — checks suspected problem areas to confirm whether moisture is actually present.
  • Water testing or leak tracing — helps isolate the path of water intrusion when the source of a leak is not obvious.
  • Adhesion testing — evaluates whether an existing surface is suitable for coatings, restoration, or other adhered systems.
  • Drone inspection — useful where roof size, access, or overall site conditions make aerial review beneficial.

The goal is to separate localized issues from broader system problems and give the owner a clear basis for deciding whether the next step should be repair, restoration, further investigation, recover, or replacement.

Specify & Design

Engineered Specifications & System Design

Some projects come to us with completed plans and specifications from an engineer, consultant, or architect, while others begin earlier, when the owner is still evaluating roof systems, developing the scope, establishing a budget, or determining whether formal engineering or design is needed. Strong works in both environments, using our experience across multiple commercial roofing, restoration, waterproofing, and fluid-applied systems to help evaluate options or execute directly from an established design. Planning and design may include:

  • System evaluation — comparing appropriate roofing, restoration, or waterproofing options based on the project conditions and owner’s objectives.
  • Scope development — helping define the work required before pricing or construction begins.
  • Budgeting and value engineering — evaluating alternatives when scope, budget, phasing, or existing conditions require another approach.
  • Consultant and engineer coordination — working directly with the owner’s existing design professionals on scoped and specified projects.
  • Design support — coordinating engineering, manufacturer requirements, details, and formal design services when the project requires them.

The goal is to develop a scope that can actually be built, priced, and executed—whether Strong is involved early in the process or brought in after the design is complete.

Self-Perform & Build

Coordinated Construction & Project Delivery

Once a project is awarded, successful construction depends on coordination between the owner, contractor, design team, manufacturers, and other parties involved. Some projects are relatively straightforward, while others require experienced management across multiple phases, trades, site conditions, and project requirements.

Project delivery may include:

  • Material procurement and submittals — coordinating approved systems, products, lead times, and manufacturer requirements.

  • Phasing and sequencing — organizing work around facility operations, weather, schedule constraints, and other project requirements.

  • Mobilization and staging — planning equipment, materials, access, loading, and site logistics before field work begins.

  • Facility protection — protecting occupied areas, equipment, entrances, landscaping, and other sensitive conditions during construction.

  • Trade coordination — sequencing roofing and waterproofing work around mechanical, electrical, structural, and other construction activities.

  • Safety planning — establishing project-specific controls, fall protection, access requirements, and site procedures.

  • Quality control and documentation — verifying installation details, documenting progress, and addressing field conditions as they arise.

  • Closeout and warranty — completing inspections, punch-list items, manufacturer requirements, warranty documentation, and final project records.

The goal is to manage the roofing and waterproofing scope from submittals through closeout, keeping field work, documentation, quality, and project coordination connected throughout construction.

Preventive Care

Preventive Maintenance, Repair & Response

Strong Contractors offers commercial roof repair, preventive maintenance, leak investigation, warranty-related maintenance, and 24/7 emergency response for owners who want to protect existing roof systems and extend their useful life. Our team can support both planned maintenance and active repair needs, from recurring problem areas and minor deficiencies to storm damage and urgent leaks. Roof care may include:

  • Scheduled inspections — reviewing the roof at regular intervals to identify developing conditions, damage, and maintenance needs.

  • Preventive maintenance — correcting minor deficiencies found during inspections before they lead to larger repairs or water intrusion.

  • Leak investigation and repair — identifying the source of active leaks and repairing the affected roofing or waterproofing components.

  • Warranty-related maintenance — completing and documenting maintenance that may be required to preserve manufacturer warranty coverage.

  • 24/7 emergency response — responding to urgent leaks, storm damage, and other conditions that require immediate attention.

  • Repair planning — helping owners determine when continued repairs make sense and when restoration or replacement should begin to be considered.

  • Maintenance documentation — creating a record of roof conditions, repairs, and recurring issues that can support future planning and budgeting.

A maintenance program does not mean every roof needs constant work. The goal is to understand how the roof is aging, address problems while they are manageable, and give the owner enough information to make decisions before an emergency makes the decision for them.

Systems

Commercial & Industrial Roofing

A commercial roof is a major building asset, and the right solution depends on more than the system that is already in place. Condition, moisture, drainage, insulation, facility operations, budget, warranty requirements, and long-term plans for the property all influence whether repair, restoration, retrofit, or replacement provides the best value.

Strong Contractors brings experience across virtually every major commercial roofing system, along with waterproofing, coatings, spray polyurethane foam, restoration, repair, and specialized services. That breadth allows us to execute projects designed to established plans and specifications or work with owners, engineers, and consultants to evaluate options and determine the most practical path forward for the facility.

Restoration

Fluid Applied Roof Systems

Fluid-applied roofing systems can be an effective way to restore and extend the service life of an existing roof without automatically moving to a full tear-off and replacement. When the existing assembly is a suitable candidate, these systems can address difficult transitions, penetrations, drainage conditions, and irregular roof geometry while creating a seamless, fully adhered protective surface.

Strong Contractors is an SPFA Accredited Contractor with extensive training and experience in spray polyurethane foam (SPF) and fluid-applied roofing systems. These systems depend heavily on proper substrate preparation, application thickness, detailing, environmental conditions, and quality control, which makes contractor experience and technical training especially important to long-term performance.

Protection

Industrial Coatings

Industrial coating systems help protect concrete, steel, and other substrates exposed to moisture, corrosion, chemicals, abrasion, and demanding operating conditions. These systems are commonly used on tanks, containment areas, concrete surfaces, structural components, and other specialized areas where durability and long-term protection are critical.

Selecting the right coating depends on the substrate, existing surface condition, service environment, chemical exposure, and expected performance of the finished system. Strong Contractors installs protective coating systems for commercial and industrial facilities, with careful attention to surface preparation, application conditions, product compatibility, and quality control—factors that directly affect adhesion, durability, and long-term performance.

Ballast Removal

Ballast removal is often a critical first step when an existing ballasted roof is being replaced, restored, or modified. On large commercial roofs, the removal method can directly affect safety, productivity, debris control, access to the underlying assembly, and coordination with the work that follows.

Strong Contractors has completed numerous large-scale commercial ballast removal projects using dedicated vacuum equipment and experienced field crews. Our equipment and project experience allow us to remove aggregate efficiently, reduce manual handling, maintain better control of site conditions, and help prepare the roof for the next phase of work.
