Our Commercial Roof Replacement Services
Complete Tear-Off & Roof System Replacement
We perform full tear-offs to remove all existing roofing materials down to the structural deck, eliminating hidden damage and excess weight from multiple roofing layers. This process ensures compliance with modern building codes and creates a clean foundation for a new system. A complete replacement allows for improved insulation, updated drainage design, and installation of longer-lasting materials backed by 20–30 year manufacturer warranties.
Roof Insulation Replacement & Energy Upgrades
We replace outdated insulation with high-efficiency materials like Polyisocyanurate (Polyiso), which offers R-values of 5.6–6.5 per inch. Proper insulation can reduce energy loss by up to 30%, significantly lowering heating and cooling costs. Our systems are designed to meet or exceed standards set by ASHRAE, ensuring optimal thermal performance and code compliance.
Hail-Damage Roof Replacement
Our hail-damage roof replacement services focus on upgrading your system with impact-resistant materials that meet UL 2218 Class 4, the highest standard for hail resistance. Given that Colorado experiences some of the highest hail frequency in the U.S., these systems are critical for protecting commercial properties. Impact-rated roofs can reduce repair frequency and may even help lower insurance premiums over time.
Flat & Low-Slope Roof Replacement
We specialize in replacing flat and low-slope roofing systems commonly found on commercial buildings throughout Denver. These systems require precise installation to prevent ponding water, which is one of the leading causes of roof failure. By combining high-performance membranes with proper slope design and drainage systems, we ensure long-term waterproofing and structural protection.
Metal Roof Replacement
Our commercial metal roof replacement services utilize durable materials such as Galvalume Steel and aluminum for long-term performance. Metal roofs can last 40–70 years and offer superior resistance to fire, wind, and hail—key concerns in Colorado. Reflective coatings improve energy efficiency, while standing seam designs provide excellent water shedding, reducing the risk of leaks from snowmelt and heavy rain.
PVC Roof Replacement
We install high-performance insulation systems using materials like Polyisocyanurate (Polyiso) to improve energy efficiency and meet Denver building codes. Proper insulation can reduce energy loss by up to 30%, which is critical in Colorado’s hot summers and cold winters. Our systems are designed to meet or exceed standards from ASHRAE, helping Denver businesses lower utility costs while staying compliant with local regulations.
EPDM Roof Replacement
Our Ethylene Propylene Diene Monomer (EPDM) roof replacement services deliver exceptional flexibility and weather resistance. EPDM can withstand temperatures as low as -40°F without cracking, making it highly effective in Denver’s freeze-thaw climate. With a lifespan of 25–30+ years and strong resistance to hail and ozone exposure, EPDM remains one of the most cost-effective commercial roofing solutions.
TPO Roof Replacement
We replace aging systems with advanced Thermoplastic Polyolefin (TPO) membranes designed for energy efficiency and long-term durability. TPO reflects up to 80% of UV radiation, which can significantly reduce cooling costs for large commercial buildings. With heat-welded seams that are up to 3x stronger than adhesive seams, TPO systems provide superior leak protection and are ideal for the intense sun exposure in Denver.
Additional Roof Replacement Services
Cool Roof Replacement
We install full-system cool roofs that reflect sunlight, reduce heat absorption, and lower energy costs for commercial properties in Denver. High-performance membranes such as TPO or PVC are engineered to meet ENERGY STAR® reflectivity standards, lowering roof surface temperatures by up to 50°F. Cool roofs not only reduce HVAC loads by 15–25% but also extend roof lifespan and protect building interiors from thermal stress caused by Denver’s intense sun and fluctuating temperatures. Optional reflective coatings can enhance UV protection and further improve energy performance.
Skylight & Roof Penetration Replacement
We replace skylights, vents, HVAC curbs, and other roof penetrations with durable, weather-resistant materials to prevent leaks and enhance energy efficiency. Over 90% of commercial roof leaks occur at penetrations and seams, so precise installation is critical. Our crews use high-quality flashing, sealants, and membranes to ensure long-term waterproofing and structural integrity, minimizing maintenance costs and protecting interior assets from water damage and weather-related deterioration.
Emergency Roof Replacement
When storms, hail, fire, or structural failures strike, we provide rapid-response emergency roof replacement to protect your property. Available 24/7, our crews quickly assess damage, stabilize the roof, and install a fully compliant replacement system. Using impact-resistant membranes, durable flashing, and proper insulation, we restore building safety and functionality while minimizing downtime. These emergency replacements are built to withstand Denver’s severe hailstorms and snow loads while meeting local building codes.
Roof Drainage & Parapet Replacement
Proper drainage and parapet systems are essential for flat and low-slope commercial roofs, especially in Denver’s freeze-thaw climate. We replace or upgrade roof drains, scuppers, downspouts, parapets, and coping to prevent ponding water, structural damage, and leaks. Our solutions improve water flow, extend roof life, and reduce maintenance costs. Combined with high-quality membranes and insulation, these upgrades protect the building envelope and ensure compliance with local building standards.
Our Commercial Roof Replacement Process
Step 1: Roof Inspection and Assessment
We start with a thorough inspection to evaluate the existing roof’s condition, structure, and drainage. Our team identifies issues like hail damage, ponding water, membrane deterioration, or insulation failures. In Denver, freeze-thaw cycles and hailstorms make this step crucial to prevent future leaks and structural problems. We document findings with photos and reports to guide the replacement plan.
Step 2: Customized Proposal & Material Selection
Next, we provide a detailed proposal outlining recommended roofing systems, timelines, and costs. Customers can choose from TPO, PVC, EPDM, metal, or energy-efficient cool roof membranes, with optional reflective coatings. We factor in Denver-specific concerns like snow loads, UV exposure, and energy efficiency standards.
Step 3: Roof Tear-Off & Deck Preparation
We remove the old roofing layers down to the structural deck, inspecting for hidden damage. Damaged decking, insulation, or fasteners are repaired or replaced. Proper deck preparation ensures a smooth, code-compliant surface for the new roof, especially critical in Denver’s variable weather conditions.
Step 4: Installation of New Membrane & Insulation
We install high-performance membranes and insulation tailored to your building’s needs. Options include TPO, PVC, or EPDM, with Polyiso insulation for energy efficiency. Seams are heat-welded or mechanically fastened for maximum durability against hail, wind, and snow.
Step 5: Flashing, Penetrations & Drainage
We install or replace flashings, skylights, HVAC curbs, drains, parapets, and coping to prevent leaks. In Denver, where ponding water from heavy snowmelt can cause early roof failure, proper drainage installation is essential for longevity and structural protection.
Step 6: Final Inspection, Warranty Handover
After completion, our team conducts a comprehensive inspection to verify watertightness, membrane integrity, and proper installation. Customers receive manufacturer and workmanship warranties, along with maintenance tips and post-installation support to maximize the lifespan of their new roof.

Commercial Roof Replacement FAQs
The timeline depends on the roof size, system type, and weather conditions. Most commercial roof replacements take 1–3 weeks for standard buildings, while larger warehouses or low-slope roofs may take longer. Denver’s seasonal weather, including snow and hail, can also affect scheduling.
Systems like TPO, PVC, EPDM, and metal roofing are ideal for Denver due to hail resistance, UV reflectivity, and freeze-thaw durability. Cool roofs with reflective membranes can also reduce energy costs during hot summers while protecting the roof from thermal stress.
Signs include leaks, ponding water, membrane cracks, blistering, or hail damage. If your roof is more than 15–20 years old, shows visible wear, or has had multiple repairs, a full replacement may be more cost-effective than continual patching.
Costs vary based on roof type, size, materials, and labor. On average, commercial roof replacements in Denver range from $6–$12 per square foot for single-ply membranes, with metal systems generally higher. A detailed, itemized proposal ensures transparency and no hidden fees.
