Selecting the right roofing system for a commercial property in Denver is not a small decision. The roofing material you choose determines how well your building stands up against hailstorms, heavy snow, strong UV exposure, and wide temperature swings. Colorado’s climate puts enormous stress on flat and low-slope roofs, which are already more prone to damage than pitched residential roofs.
In recent years, TPO (Thermoplastic Polyolefin) membranes have grown in popularity for their affordability and energy efficiency. Within this category, Fleece-Back TPO roofing has emerged as one of the most advanced solutions available for commercial buildings. But is it worth the investment? This article explores everything you need to know—benefits, installation, comparisons, and considerations—so you can make an informed decision for your property.
Understanding Fleece-Back TPO Roofing
What Is Fleece-Back TPO?
Fleece-Back TPO is an upgraded version of traditional TPO roofing. It consists of:
- A TPO membrane: a single-ply layer made from polypropylene and ethylene-propylene rubber.
- A fleece backing: a fabric-like layer bonded to the underside.
This configuration creates a roofing system that is tougher, more flexible, and more resilient than standard membranes.
The fleece backing provides several enhancements:
- Cushion against impacts: Resists punctures from hail or rooftop activity.
- Stronger adhesion: Bonds securely to the roof deck, even on complex surfaces.
- Extra insulation: Reduces heat transfer, stabilizing indoor temperatures.
For Denver businesses, where climate challenges are severe, these benefits make a measurable difference.
How Fleece-Back TPO Is Manufactured
The durability of fleece-back TPO is not by chance—it comes from a precise manufacturing process:
- Base Membrane Creation: Polymers are combined and reinforced into a thermoplastic sheet.
- Bonding the Fleece: A fleece layer is laminated to the underside using advanced hot-melt coating technology.
- Quality Testing: Each sheet is tested for tensile strength, puncture resistance, and seam weldability.
This strict quality control ensures the product meets the demands of commercial roofing in challenging environments like Denver.
Advantages of Fleece-Back TPO
Enhanced Durability
Commercial roofs endure heavy wear from foot traffic, equipment, and severe weather. The fleece cushion reduces the risk of punctures, while the reinforced membrane prevents tearing.
- Protects against hail damage.
- Extends roof lifespan.
- Reduces repair frequency and costs.
Energy Efficiency
Denver businesses face rising energy bills from extreme seasonal shifts. Fleece-Back TPO addresses this with:
- A reflective surface that deflects UV rays.
- Improved insulation from the fleece layer.
- Lower heating and cooling costs year-round.
Weather Resistance
Fleece-Back TPO is engineered to resist:
- Freeze-thaw cycles common in Colorado winters.
- UV degradation at high altitudes.
- Standing water on flat roofs.
Installation Flexibility
Depending on the building, fleece-back TPO can be:
- Fully adhered with adhesives.
- Mechanically attached with fasteners.
- Ballasted with gravel or pavers.
This adaptability makes it suitable for a variety of commercial properties—from warehouses to retail centers.

The Installation Process
Installing fleece-back TPO requires expertise and precision. At Commercial Roofing Denver, we follow a structured process:
1. Preparation
- Remove old materials and debris.
- Inspect for moisture or structural issues.
- Apply primers if needed for better adhesion.
2. Application
- Membranes are laid out and secured via adhesives, fasteners, or ballast.
- The fleece layer improves bonding and minimizes slippage.
3. Seaming
- Hot-air welders create watertight seams stronger than the membrane itself.
4. Inspection
- Every seam and penetration is checked.
- Manufacturer representatives may inspect for warranty approval.
