When it comes to commercial roof recovery, metal roof retrofits with single-ply roofing systems, such as TPO (Thermoplastic Polyolefin), are becoming the go-to solution. This modern roofing technology offers a cost-effective, durable, and energy-efficient way to extend the life of your roof while minimizing business disruptions. At Browns Roofing, we specialize in providing high-quality roofing solutions designed to protect your property for years to come. Below, we’ll explore what a TPO retrofit is, its benefits, and why it’s an ideal solution for commercial buildings.
What Is a TPO Retrofit?
A TPO retrofit is a type of single-ply roofing system installed over an existing metal roof. Instead of removing and disposing of the old roof, the TPO retrofit system is layered directly over the existing substrate. This system typically includes:
- Flute Fill Insulation: Used to level the surface and enhance energy efficiency.
- Fiber Boards: Provide a sturdy base for the new membrane.
- TPO Membrane: A durable and flexible material that protects against weather, UV rays, and chemical exposure.
This innovative approach not only extends the lifespan of your metal roof by up to 20 years but also creates a sleek, modern look with minimal waste and disruption.

How Are TPO Retrofits Installed?
There are two primary methods for installing TPO retrofits: Mechanically Attached and Fully Adhered. Both methods offer unique advantages depending on your building’s needs.
Mechanically Attached
- The TPO membrane is fastened to the roof’s purlins using plates and fasteners, eliminating the need for adhesives.
- This method offers moderate wind uplift performance and is ideal for areas with less extreme weather.
Fully Adhered
- Insulation is attached with fasteners and plates, and the TPO membrane is bonded using adhesives.
- This method allows for wider TPO sheets, resulting in fewer seams and superior wind uplift resistance.
Both methods are quick and efficient, making them great options for commercial roof recovery.
Why Choose a TPO Retrofit for Metal Roofs?
Upgrading your commercial building to a single-ply TPO retrofit system comes with numerous benefits:
- Extended Roof Lifespan: TPO retrofits can add up to two decades of life to your existing roof.
- Minimal Disruption: The installation process is quick and doesn’t require tearing off the old roof, reducing downtime for your business.
- Energy Efficiency: TPO membranes reflect sunlight, reducing heat absorption and lowering energy costs.
- Low Maintenance: The durable material resists punctures, tears, and chemical exposure, requiring little upkeep.
- Cost Savings: With no need for roof removal, disposal costs are significantly reduced.

Applications for Single-Ply Roofing Systems
TPO retrofits are highly versatile and can be used on a wide range of commercial buildings, including:
- Storage Facilities: Offering superior protection against leaks and temperature fluctuations.
- Retail Stores: Enhancing curb appeal while improving energy efficiency.
- Educational Institutions: Providing safe, long-lasting roofing for schools and universities.
- Industrial Buildings: Withstanding harsh conditions like chemical exposure and heavy equipment operations.
- Multi-Family Complexes: Protecting large-scale residential buildings from weather damage.
- Religious Buildings: Preserving the integrity of historic or modern worship spaces.
