About Pillar Roofing
Every Detail. Every Step. Every Time
Every Detail Matters.
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
Heavy Rain Drain
Each custom overflow scupper begins with a sheet metal insert. We form and heat-weld the TPO flashing around the opening, then seal the interior and exterior details to direct overflow water through the parapet.
The roof side details are molded and heat-welded together to form the shape of the scupper drains. Once the interior side is welded and sealed, the outside exposed scupper is waterproofed and heat-welded flush with the parapet wall detail.
These custom scupper drains will handle the overflow rainwater during heavy downpours.
About Pillar Roofing
What's Under The TPO
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.

Rainwater Management
The illustration shows that 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.

New Drain - New Flow
TPO drain inserts are replaceable, improving water flow and giving the drainage system new life.
A properly fitted drain grill helps prevent leaves, dirt, and debris from clogging the drain and obstructing rainwater flow.
