Why Choose Core
Why Choose Core Roofing for Low-Slope Installation
Versico Authorized Contractor
We’re an official Versico Roofing Systems Authorized Contractor, qualifying us to install TPO, PVC, and EPDM systems with full manufacturer backing and access to premium materials that non-authorized contractors cannot source.
25+ Years of Commercial Roofing Experience
Our team has completed low-slope installations on office parks, retail centers, industrial facilities, and multifamily complexes. That depth of real-world experience means we spot potential issues during pre-installation assessment and design systems that perform in Denver’s weather.
Denver Business Journal Recognition & CIVIC50 Distinction
We’ve been honored as a Small Business of the Year and recognized for community involvement. That reputation reflects our commitment to quality on every project, including low-slope installations where durability directly affects your building’s bottom line.
Comprehensive Drainage Design & Slope Verification
Low-slope systems require careful attention to water flow. We conduct detailed site assessments, confirm existing slope (or design new slope with tapered insulation), and position drains strategically so water never pools. Our inspection process includes thermal imaging to identify potential wet insulation before it becomes a problem.
Full Warranty Documentation & Long-Term Support
Every installation comes with a 5-year Core Roofing workmanship guarantee, plus the full manufacturer warranty on materials. We maintain detailed documentation and are here to support your facility long after installation.
Transparent Process from Assessment to Completion
We start with a thorough site assessment to understand your building’s needs, provide a clear written estimate, and keep you informed throughout the installation. No surprises, no hidden costs — just honest, professional service.

Our Process
Our Low-Slope Installation Process
Pre-Installation Site Assessment & Design Consultation
We begin with a detailed walkthrough of your building. Our team measures existing roof dimensions, evaluates current conditions (whether you’re stripping an old system or building on a new structure), confirms slope or designs tapered insulation to achieve proper drainage, and identifies drain locations and guttering requirements. We photograph everything and create a scope document that outlines material choices, cost, timeline, and any structural or drainage concerns we’ve identified.
Material Selection & Logistics Planning
Once you’ve approved the scope, we finalize material specifications—whether TPO, PVC, or EPDM—and coordinate delivery. Low-slope systems ship in large rolls, and we schedule delivery to align with your construction window. Our crew preps the staging area, establishes safety protocols (including fall protection, equipment placement, and traffic management), and confirms utility locations.
Surface Preparation & Insulation Installation
All existing roof material, debris, and failed insulation is removed and disposed of responsibly. We inspect the underlying roof deck (concrete, steel, wood) for damage and repair as needed. If the roof requires new slope, we install tapered rigid insulation boards to direct water toward drains. All fasteners, tape, and adhesives are applied per manufacturer specs—this layer is where water management begins.
Membrane Installation & Seam Sealing
Our certified installers unroll the membrane (TPO, PVC, or EPDM) across the prepared surface, securing it at edges and around all penetrations. Seams are sealed using the membrane manufacturer’s approved method—heat-welding for TPO/PVC, adhesive or tape for EPDM—and tested for watertightness. This is where the system’s longevity is determined; poor seam quality is the #1 cause of low-slope failures.
Final Inspection, Testing & Walkthrough
Before we hand off the project, we conduct a final walkthrough with you. We test the drainage system (simulating heavy rain), verify all seams and flashings, and provide you with a complete photographic record, warranty documentation, maintenance guidelines, and our contact information for future questions or maintenance needs.

Doing It Right Matters
Ready to Protect Your Building With Expert Low-Slope Installation?
A low-slope roof is a 15–20 year investment in your building’s structural integrity and operational efficiency. The right material, proper installation, and thorough documentation make all the difference. We’ve completed hundreds of commercial installations across Denver and the region. Our Versico authorization, Owens Corning partnership, and 25+ years in commercial roofing mean your project gets the expertise and attention it deserves.
Every low-slope installation is unique. Your building’s size, existing conditions, local climate exposure, and budget priorities all influence material selection and process design. That’s why we spend time on the front end—our pre-installation assessment isn’t a quick walk-through, it’s a detailed engineering review that catches potential issues before they become expensive problems. Financing is available to help spread the cost of replacement projects, and maintenance planning is included with every installation.
