TPO roofing is one of the most widely used flat roofing systems for both residential and commercial properties. Throughout the Greater Philadelphia Area, TPO is commonly installed on flat and low-slope roofs due to its energy efficiency, durability, and clean appearance. TPO (Thermoplastic Polyolefin) is a single-ply membrane designed to create a watertight, heat-reflective roofing system.
One of the main advantages of TPO roofing is its ability to reflect sunlight. Unlike darker roofing systems, TPO membranes are typically white or light-colored, which reduces heat absorption and can improve energy efficiency — especially during warmer months. TPO is ideal for properties where energy performance, durability, and a clean modern appearance are the priority.

A TPO roofing system is a single-ply membrane system designed for flat or low-slope roofs. Instead of individual components like shingles, TPO uses large sheets of membrane that are installed across the roof to create a continuous waterproof surface.
What makes TPO different from other flat roofing systems is its heat-welded seams, which create a strong, watertight bond between membrane sections.
Every project begins with a complete tear-off of the existing roofing system. All membranes, flashings, adhesives, and components are removed. Nothing is reused.
This ensures a clean and stable foundation for the new system.
Insulation is installed over the roof deck to create a smooth and energy-efficient base. Common insulation thicknesses include ½ inch, 1 inch, 2 inches, 3 inches, 4 inches, and 5 inches. The correct thickness depends on the property type, energy efficiency goals, budget, and existing roof conditions. Thicker insulation can improve thermal performance and reduce energy costs.

The TPO membrane is rolled out and positioned across the roof. This ensures proper alignment before fastening and welding begin. Proper layout prevents wrinkles and ensures consistent seam alignment.
The membrane is secured using mechanical fasteners or a fully adhered system. This step ensures the membrane stays in place and resists wind uplift.
Seams are welded together using heat. This is one of the most important advantages of TPO roofing. Unlike taped seams, heat welding fuses the material together, creates a watertight bond, and reduces the risk of seam failure. Proper welding is critical to long-term performance.
All flashing is installed at walls, curbs, HVAC units, pipes and penetrations, and drains. These areas are the most vulnerable points on a flat roof.
Drainage is evaluated and adjusted. Flat roofs must move water efficiently to prevent ponding.
The completed system is inspected, every seam is checked, the site is cleaned, and a final walkthrough is completed.
TPO roofing systems are designed to last 20–30+ years, and in some cases longer with proper maintenance. Because of this, flashing materials must be able to perform over time.
Using heavy-gauge metal flashing (.032 or greater), or copper flashing in critical areas, helps ensure that these vulnerable areas do not fail before the membrane itself.
We had a very positive experience with Shelby Roofing Services and are extremely happy with our new EPDM flat roof. From the estimate through installation, everything was handled professionally and on time.
Shelby Roofing Services installs both mechanically attached and fully adhered TPO systems. The right choice depends on the size of the roof, your budget, and the finish you want.
The membrane is secured to the roof with mechanical fasteners. This system is best when:
The membrane is bonded to the roof with adhesive. This system is best when:
| Feature | Mechanically Attached | Fully Adhered |
|---|---|---|
| Attachment | Fasteners | Adhesive |
| Cost | Lower | Higher |
| Membrane Movement | Moderate | Minimal |
| Best For | Large roof areas and cost-effective installs | A strong bond and a cleaner appearance |
A properly installed TPO roof lasts 20–30+ years, and in some cases longer with proper maintenance.
No two flat roofs are exactly the same, so the price of a TPO roof varies from property to property.
An inspection is required to give you an accurate price. We provide detailed, itemized proposals before any work begins.
Every TPO roof we install is backed by two warranties.
Covers the TPO roofing materials themselves.
Shelby Roofing Services’ own warranty covers the installation.
Both warranties are transferable, so the protection stays with the property if it is sold.
TPO requires precision. Even the best membrane will not perform if the seams, flashing, and drainage are not installed correctly.
We handle everything, including the permit process.

Shelby Roofing Services is based in Blue Bell, PA and installs TPO flat roofing on residential and commercial properties throughout Pennsylvania, New Jersey, and Delaware.
It depends on your goals: energy efficiency versus flexibility. TPO is a white thermoplastic membrane with heat-welded seams, preferred for energy efficiency and a clean, modern look. EPDM is a rubber membrane, preferred for extreme temperature flexibility and long-term durability. We assess your property and goals to recommend the right system.
Yes. TPO is highly reflective. The membrane is typically white or light-colored, which reflects sunlight, reduces heat absorption, and can improve energy efficiency, especially during warmer months.
A properly installed TPO roof typically lasts 20–30+ years, depending on installation, maintenance, and exposure. Quality of installation is the single biggest factor in TPO longevity.
Every flat roof is different, and the most accurate way to know the cost is a free inspection. Price depends on the size of the roof, the membrane system, insulation and drainage needs, and the condition of the deck underneath. We provide a free inspection and a personalized, itemized written estimate for your property — no pressure and no obligation. Call (215) 847-3522.
Yes. TPO is an excellent choice for flat or low-slope residential roofs, including additions, garages, and multi-level homes. Its clean white appearance and energy performance make it a popular choice for modern properties.
No. Every TPO project begins with a complete tear-off. All membranes, flashings, adhesives, and components are removed, and nothing is reused.
We provide detailed inspections and recommendations tailored to your property. If you are considering a new TPO roof, Shelby Roofing Services will assess your current system, walk you through your options, and provide a clear, detailed proposal at no cost.
