Manufacturer Certifications That Enable Quality Control

Our Owens Corning Platinum Preferred and Versico Authorized contractor status means we have direct access to premium materials, manufacturer-level technical support, and certification-backed installation standards that exceed industry minimums. When you hire a certified contractor, the manufacturer backs the installation — giving you manufacturer warranty coverage that non-certified installers simply cannot provide.

Expertise Across Every Commercial System Type

We install TPO, PVC, EPDM, low-slope membranes, and modified bitumen roofing on commercial properties across Denver and the surrounding metro area. Each system has unique installation requirements, material specifications, moisture management demands, and performance characteristics that differ significantly. Our broad experience across all systems means we can recommend the right choice for your building’s specific exposure, climate zone, and use case.

Certified Installation Process That Ensures Long-Term Longevity

Commercial roof installation isn’t just laying material down; it’s a precision engineering process. Proper substrate preparation, correct fastening patterns and fastener spacing, appropriate flashing details, waterproof sealing of all penetrations, and proper edge details all critically affect long-term performance and warranty validity. Our team follows certified manufacturer installation protocols to the letter.

Dual Protection: 5-Year Workmanship Guarantee + Manufacturer Warranties

We back our labor with a comprehensive 5-year workmanship guarantee that covers any defects in installation quality or workmanship. The manufacturer backs the materials with typically 10–20 year material warranties depending on the specific system chosen. Together, these protections mean your installation is fully covered for both labor quality and material performance.

That hands-on experience means fewer surprises, faster project completion, and installations that consistently meet deadline and budget expectations.

Our Process

Our Commercial Roof Installation Process

Core Roofing Systems crew working on a commercial roof installation in Denver
  1. 01

    Consultation & Existing Roof Assessment

    Your project begins with a detailed consultation where we discuss your building’s condition, use case, budget expectations, and timeline. If you have an existing roof, we conduct a comprehensive assessment including membrane testing, flashing evaluation, and structural substrate review. We document findings and answer questions about what we’re observing — no mystery, no surprises.

  2. 02

    System Selection & Design

    Based on our detailed assessment, we present roofing system options matched to your building’s specific needs, exposure, climate, and budget. We thoroughly discuss the pros and cons of each option — material cost, energy efficiency performance, expected longevity, maintenance requirements, and local Denver climate performance. Our goal is to recommend the system that delivers the best value for your building’s specific situation.

  3. 03

    Material Procurement & Scheduling Coordination

    Once you approve the system and budget, we procure all materials and coordinate scheduling with your building management. We plan installation timing to minimize disruption to occupants and operations. For larger projects, we may structure phased installation to keep portions of the roof operational while we work.

  4. 04

    Professional Installation

    Our certified installation team executes the installation following manufacturer specifications and our certified installation protocols. This includes substrate preparation, proper fastening, flashing installation, penetration sealing, and quality checkpoints throughout the process.

  5. 05

    Final Inspection & Warranty Handoff

    Once installation is complete, we conduct a comprehensive final inspection, document the work, and provide all warranty documentation. You’ll receive a detailed summary of the work completed, warranty terms, maintenance recommendations, and contact information for future support.

Commercial Roof Installation Questions

Timeline depends on roof size, system type, weather, and whether you have an existing roof to remove. A single-story office building might take 2–4 weeks; larger facilities or buildings with existing roofs to remove may take 6–12 weeks. We provide a detailed project schedule during planning and keep you updated throughout.

Absolutely. We’re experienced in working around active tenant schedules and operational requirements. We restrict access to work areas, manage dust and noise throughout the workday, and coordinate closely with your property management to maintain building operations. For larger projects or buildings with noise-sensitive tenants, we often schedule critical work phases during evening, weekend, or after-hours periods to minimize operational impact.

TPO offers excellent energy efficiency and cost-to-value economics on single-ply membrane systems, making it popular for new construction. PVC excels in chemical resistance and UV stability, making it ideal for industrial, chemical, or food processing facilities where standard membranes may degrade. EPDM is a proven, time-tested system that’s durable, budget-friendly, and performs reliably across most climates. Low-slope refers to roof pitch (typically less than 2:12) and the water management system design required. The right choice depends on your building’s specific exposure, geographic climate zone, maintenance budget, and longevity goals.

Properly installed commercial roofs typically last 15–25 years depending on the system type, local climate, maintenance frequency, and environmental exposure. We install all systems to strict manufacturer specifications to maximize design lifespan and maintain warranty validity. Our 5-year workmanship guarantee and manufacturer material warranties protect your investment during the critical early years. With proactive annual maintenance and inspections, your roof investment will deliver decades of reliable protection against the elements.

Overlaying (installing over an existing roof) may be possible in some cases depending on existing roof condition and local Denver building codes. However, a full removal and replacement is usually the superior long-term approach because it allows us to thoroughly inspect the underlying substrate, repair any moisture damage or structural issues, and ensure proper installation of the new system from the substrate up. A full replacement guarantees optimal performance and warranty validity. We’ll assess your existing roof during consultation and recommend the best approach based on condition and building requirements.

Substrate issues — soft wood, moisture damage, structural decay — discovered during installation are addressed before the new roof goes on. We document all findings and repair costs clearly, with repairs charged separately from the base installation if they weren’t anticipated in the initial scope. Addressing substrate problems comprehensively up front prevents roof failures later and extends your new system’s lifespan. A properly prepared substrate is essential to warranty validity and long-term roof performance.

Yes, comprehensively. Our 5-year workmanship guarantee covers all labor and installation quality — if an installation defect occurs within five years, we repair it at no charge. The manufacturer warranty covers the roofing materials themselves, typically ranging from 10–20 years depending on the specific system and product selected. Both warranties work together to provide complete protection: manufacturer covers material defects, and we cover workmanship. Detailed warranty documentation is provided at project completion, including coverage terms and claim procedures.

Yes, absolutely. Rooftop HVAC units, condensers, antennas, solar arrays, and other equipment require extremely careful planning and precise flashing design during installation. We design custom flashing solutions that work around existing equipment without compromising the roof’s performance, properly seal all penetrations to prevent water intrusion, and coordinate closely with your facilities team to minimize equipment downtime during our work. Our attention to equipment protection is a key part of quality installation.

Yes. We offer flexible financing options to help fit commercial roofing into your capital budget. Discuss timing and terms with our team during the planning phase.

Maintenance depends on the system, but typically includes: annual inspections, keeping drains and gutters clear, addressing any debris accumulation, and having us inspect after major weather events. We provide detailed maintenance recommendations specific to your system at project completion.
