COMMERCIAL ROOFING & WATERPROOFING CONTRACTOR

What 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 — Evaluate 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 still depends on understanding the existing conditions. An assessment and diagnosis should give an owner a clear picture of where things stand and what options are available. That first conversation and assessment 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

We never guess at a roof’s condition. Using non-destructive moisture scans, core sampling, and high-resolution drone imaging, we map the exact health of your building envelope before recommending a path forward.

Specify & Design

Engineered Specifications & System Design

Every recommendation is backed by an engineered spec, not a sales pitch. We translate diagnostic findings into a complete system design, material selection, attachment method, and detail drawings, reviewed before a single crew mobilizes.

  • Manufacturer-matched system selection and wind uplift calculations
  • Detail drawings for every penetration, curb, and transition
  • Value-engineered alternates when budget or timeline require them
Self-Perform & Build

Self-Performed Installation, Start to Finish

We don’t subcontract the work that matters. Every crew on your roof is a Strong Contractors employee, trained and certified on the system being installed, working from the spec our own team engineered.

  • In-house crews certified on every membrane and coating system we install
  • Daily progress photos and quality checkpoints at every phase
  • Single point of accountability from mobilization to final walkthrough
Preventive Care

Preventive Maintenance & Asset Life Extension

A roof’s biggest expense is usually the one that could’ve been prevented. Scheduled inspections, minor repairs, and drainage clearing catch small issues before they become capital expenses — extending system life well past its original warranty term.

  • Scheduled inspections tied to manufacturer warranty requirements
  • Minor repairs and drainage clearing bundled into routine visits
  • Condition reports that feed directly into your capital planning
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.

Operations

Specialized Services

For Colorado facilities, Strong Contractors provides emergency roof repair and ongoing maintenance plans to address active issues, reduce recurring problems, and help owners stay ahead of larger roofing failures. Strategic repairs and maintenance can extend the useful life of an existing roof, help bridge the time until a larger capital project is planned, and support manufacturer warranty requirements where ongoing maintenance is required.

Strong Contractors also provides specialized building-envelope services, including air and vapor barrier systems and below-grade waterproofing. Our experience includes large-scale industrial and complex new-construction scopes where sequencing, access, detailing, and coordination are critical.
