Energy-Efficient, Durable Roofing Built for Commercial Properties


About Pillar Roofing
A successful TPO roofing installation depends on far more than simply rolling out membrane. The Pillar Roofing Coordinator oversees every phase of the project—from material deliveries and crew logistics to safety compliance, installation sequencing, seam quality, drainage details, and manufacturer specifications.
Throughout the installation, every critical component is monitored, documented, and verified before the project moves forward. As the work nears completion, the coordinator develops and manages the punch list, ensuring every detail is addressed before final acceptance.
This disciplined oversight helps deliver a roofing system built to perform reliably for decades—not just pass inspection on the day it's installed.

About Pillar Roofing
The custom overflow scupper drains starts with a sheet metal square insert that been coated with TPO is installed .
The roof side details are molded and heat welded together to form the shape of the scupper drains. Once the interior side are welded and sealed up, the outside exposed scupper is waterproofed and heat welded flush with the parapet wall detail.
These custom scupper drain will handle the overflow rainwater during heavy downpours.

About Pillar Roofing
A quality TPO roof is built as a complete system, not simply a sheet of membrane laid over insulation. Installing the insulation in two staggered layers prevents the board joints from lining up and creating continuous gaps through the assembly.
This helps reduce heat loss, limits air movement, distributes loads more evenly, and creates a stable surface beneath the membrane. Properly fitted and staggered insulation also reduces movement that could eventually become visible through the finished roof.
The protective cover board provides an additional layer of strength between the insulation and the TPO membrane. It creates a smooth, durable surface while helping protect the softer insulation from foot traffic, tools, service work, hail and other impacts. By improving puncture resistance and distributing pressure across the roof system, the cover board can extend the service life of the membrane—especially around rooftop equipment and other regularly accessed areas.

Crickets and Saddles are shaped slopes installed beneath the TPO membrane, often using tapered insulation, to direct rainwater around rooftop equipment, curbs and other obstructions.
These raised areas divide the water and guide it into drainage paths leading toward the roof drains, helping minimize low spots where water could collect and pond.
Primary drains handle normal rainfall, while properly placed scuppers carry water through the roof edge.
When designed as secondary overflow drainage, scuppers provide an important backup if the primary drains become blocked or cannot handle a heavy storm.

Get durable, low-maintenance roof protection that reduces cooling costs and stands up to Texas weather.

About Pillar Roofing
TPO drain inserts are replaceable, improving water flow and giving the drainage system new life.
A properly fitted drain grill helps prevent system clogs from leaves, dirt, and other debris that can obstruct rainwater flow.
Ask your Pillar Roofing Coordinator about our scheduled maintenance program.
Avoid this drain insert replacement by checking and clearing your drainage areas twice a year.
Many commercial buildings have aging modified bitumen or built-up roofing systems that remain structurally sound but have reached the end of their service life. In many cases, a complete tear-off is unnecessary.

Thermoplastic Polyolefin (TPO) roofing systems are among the most popular commercial roofing solutions available today. TPO membranes provide excellent resistance to UV exposure, ponding water, weathering, and temperature fluctuations while delivering outstanding energy efficiency through their highly reflective surface.
The TPO membrane is mechanically fastened or fully adhered according to manufacturer specifications. All seams are heat welded to create a monolithic waterproof surface that provides exceptional long-term protection against leaks and weather intrusion.

A fully adhered TPO roofing system provides one of the most attractive and durable solutions for commercial flat roofing applications. Unlike mechanically attached systems, the membrane is bonded directly to the insulation substrate using manufacturer-approved adhesives, creating a smooth, uniform appearance with exceptional wind uplift performance.
A mechanically attached TPO recover system allows building owners to install a new roofing assembly directly over the existing roof after repairs and preparation have been completed. This approach reduces disruption, minimizes landfill waste, and often provides a more economical solution than a full replacement.
Automated hot-air welding technology to create strong, consistent membrane seams. Robotic seam welders maintain precise temperature, pressure, and travel speed throughout the welding process, producing uniform welds across long roof runs.

Many commercial buildings still have older built-up roofing (BUR) systems consisting of multiple layers of asphalt, felts, and embedded gravel. While these roofs can often be restored rather than completely torn off, proper surface preparation is absolutely critical to the success of the new roofing system.
Our restoration process begins with the removal of loose gravel and surface contaminants using specialized vacuum equipment. The existing roof is then mechanically prepared using rotary wire-brush machinery to create a clean, stable substrate for the new roofing assembly.
A Smart Alternative to Tear-Off
The RhinoBond TPO Roofing System combines the strength of a mechanically attached roofing system with the performance benefits of a fully adhered membrane. Using advanced induction-weld technology, the TPO membrane is securely bonded to specially engineered attachment plates beneath the roof surface, creating a stronger and more uniform attachment across the entire roof.

Key Benefits
Superior wind uplift performance for Texas weather conditions
Reduced membrane movement and roof flutter
Enhanced long-term durability and system longevity
Excellent performance on large commercial, industrial, and aviation facilities
Energy-efficient reflective TPO membrane helps reduce cooling costs
No field-applied bonding adhesives required
Proven technology trusted on warehouses, manufacturing plants, distribution centers, and airport facilities
Crickets and saddles are engineered insulation structures designed to redirect water around rooftop equipment, curbs, and other obstructions, allowing water to flow efficiently toward roof drains, gutters, and designated drainage points.

By eliminating areas where water can become trapped, these drainage enhancements help extend the service life of the roofing system, reduce maintenance concerns, and improve overall roof performance.

Benefits
Promotes positive water drainage across the roof surface
Reduces ponding water and moisture-related deterioration
Directs water around HVAC units and rooftop obstructions
Improves long-term performance of the TPO roofing system
Designed specifically for the roof's drainage layout and water flow patterns
Supports a cleaner, drier, and more efficient roofing system

As part of the roofing system upgrade, all rooftop HVAC equipment will be secured using reinforced TPO attachment straps specifically designed for use with the new roofing membrane.
The straps are mechanically attached to the HVAC support structure and heat-welded directly to the new TPO roofing membrane, creating a secure and watertight attachment system. This method helps resist movement, uplift, and displacement of rooftop equipment during high-wind events while maintaining the integrity of the roofing system.
Benefits
Improved resistance to high-wind uplift forces
Additional protection for rooftop HVAC equipment
Heat-welded watertight attachment system
No exposed fasteners through the roofing membrane
Designed to complement the Carlisle TPO roofing system
Ideal for airport, industrial, and commercial facilities exposed to elevated wind conditions

About Pillar Roofing
The transformation from an aging, torn-up Modified Bitumen Roof System to a new, brilliant white, energy-efficient TPO Membrane was amazing to see.
