Scope of work

What TPO is and where it fits

TPO is a single-ply membrane: one flexible white sheet, heat-welded at the seams into a continuous watertight skin. It is the most common choice on low-slope commercial roofs today, and the white surface reflects Texas sun instead of soaking it in, which shows up on summer cooling bills.

Weld quality decides how a TPO roof ages, since seams are where membranes fail. The roofer installs to the manufacturer's spec, seams machine-welded and tested as the work goes, which is also what keeps the material warranty valid. Expect roughly 20 to 30 years from a well-installed, maintained system.

When to replace

When TPO is the right system

Not every building wants the same membrane. TPO earns its place when these fit.

A standard low-slope deck

Offices, retail, warehouse: TPO's home territory.

Cooling costs matter

The reflective surface works hard against North Texas summers.

A 20-to-30-year horizon

Owners planning a normal capital cycle, not a century hold.

Grease or chemical exhaust

Kitchen exhaust degrades some membranes. The survey flags when a different sheet fits better.

How it works

3

Weld and test

Membrane laid, seams machine-welded and probe-tested.

4

Detail and document

TPO questions

What owners ask before committing to a membrane.

Twenty to thirty years is the honest range for a properly installed and maintained system. Thickness matters, 60 or 80 mil outlasts 45, and so does drain maintenance: standing water ages any membrane faster than sun does.
Better for most buildings here, not all. EPDM's black rubber has a long track record; PVC resists kitchen grease, which makes it the pick over restaurant exhaust. TPO wins the general case on weldability, reflectivity, and price. The survey names which fits your building.
Code allows one recover if the existing assembly is dry and the building is not already carrying two roofs. A moisture survey settles it: recovering over wet insulation just seals the problem in, and no honest roofer will do it.
Modest but real: drains kept clear, seams and flashings looked at yearly, and foot traffic kept to walk pads. A maintenance-minded inspection once a year is the cheapest insurance a flat roof can buy.
