TPO Roof Installation by ARCM Roofing
Heat-welded thermoplastic membranes for commercial buildings — energy-efficient white roofing with seams stronger than the sheet itself.
5 Highlights on TPO Installation
The Commercial Standard, Welded to Spec
The most-installed single-ply in American commercial roofing — where EPDM owns residential-scale rubber, TPO owns the reflective commercial field, part of our full flat roofing practice.
Heat-Welded Seams
Every seam fused with hot-air welders into a monolithic surface — stronger than the membrane itself when welded right, and we probe every one to prove it.
87% Solar Reflectance
Energy Star white TPO bounces solar radiation before it heats your building — facilities switching from black roofs often cut summer cooling 15-30%.
Three Attachment Methods
Fully adhered, mechanically fastened, or induction welded — specified to your building's wind uplift requirements, not a one-size default.
45, 60, and 80 Mil Options
Membrane thickness matched to foot traffic, budget, and expected service life.
Calibrated Welding Discipline
Weld temperature tested throughout the day as conditions change, seams probed after welding, cut tests performed — documented for the manufacturer's warranty inspector.
We probe every seam before the warranty inspector does.
Why Choose Us
Millions of Square Feet, Probed Seam by Seam
We've installed millions of square feet of single-ply, and the experience shows in welding discipline: seam temperatures tested through the day as conditions change, every seam probed after welding, cut tests documented. Our manufacturer certifications qualify your roof for extended warranties to 30 years, installed to National Roofing Contractors Association standards.
In-house sheet metal fabrication produces the custom edge metal, coping, and flashing your parapets need — no waiting on suppliers. Dedicated project managers coordinate scheduling around your business operations, and the building stays watertight at the end of every workday.
Ask for references: we'll provide addresses of TPO roofs we installed ten years ago that still perform today — backed then and now by our written labor warranty on top of manufacturer coverage.
Warning lines and personal fall arrest on every roof, materials staged clear of walkways, daily safety briefings, site secured each evening.
When It Makes Sense
Signs TPO Is the Right Replacement
Your EPDM Is Shrinking Off the Walls
EPDM roofs pull away from parapet walls after 20 years, bridging corners and tearing at terminations. When repairs outpace their value, a new heat-welded TPO membrane makes financial sense.
Summer Cooling Bills Keep Climbing
Dark roof surfaces absorb heat and push it into your building all afternoon. Facilities with black EPDM or asphalt built-up roofs often see summer energy costs drop 15 to 30 percent after switching to reflective white TPO.
Recurring Leaks at Seams and Penetrations
Failed lap seams, cracked pitch pockets, and deteriorated pipe boots let water into the assembly. Once moisture saturates the insulation, surface patches solve nothing — tear-off and replacement removes the wet material.
Ponding Water That Won't Drain
Standing water degrades most membranes and voids many warranties. During TPO installation we correct slope with tapered insulation that directs water to drains and scuppers.
Blistering or Splitting Built-Up Roof
Alligatoring and splitting signal oxidized asphalt that's lost its flexibility, and cold accelerates the cracking. Single-ply TPO flexes with thermal movement and shrugs off the freeze-thaw cycles that destroy aged BUR.

How We Work
Our TPO Installation Process
01
Assessment and Core Sampling
Existing assembly inspected, core samples cut, infrared moisture scan run to map wet insulation.
02
Detailed Proposal
Written scope covering membrane thickness, insulation R-value, attachment method, flashing details, and warranty terms. No vague line items.
03
Tear-Off or Recover Prep
Saturated materials removed to deck, or the existing roof prepared for a recover board — whichever the assessment proved right.
04
Insulation Installation
Polyiso boards fastened to the deck, tapered systems added where drainage needs correction.
05
Membrane and Welding
TPO sheets attached per the specified system, every seam heat-welded with calibrated hot-air welders.
06
Flashing and Details
Curbs, pipes, drains, and walls flashed with TPO accessories; terminations sealed with bar and sealant.
07
Quality Inspection
All seams probed, cut tests performed, and the roof walked with you before the manufacturer's inspector reviews it for warranty issuance.
Most commercial installations finish in one to three weeks — watertight at the end of every workday.

FAQs
FAQs About TPO Installation
›What is TPO roof installation?
TPO roof installation is the process of attaching a thermoplastic polyolefin membrane to a commercial roof deck over insulation, then heat welding the seams to create a watertight surface. It's the most popular single-ply system in the US commercial market.
›How long does TPO roof installation take?
Most projects take one to three weeks. A 20,000 square foot recover installation might finish in five working days, while a full tear-off with tapered insulation takes longer.
›How much does TPO roof installation cost?
Pricing typically runs $5.50 to $12 per square foot depending on membrane thickness, insulation requirements, tear-off scope, and roof access. We provide itemized quotes after inspecting your roof.
›Can you install TPO over an existing roof?
Yes, in many cases. Building codes allow one recover over an existing roof if the insulation stays dry and the deck remains sound. Our moisture scan determines eligibility.
›Why do the seams matter so much?
Seams are where most flat roofs fail. Heat-welded TPO seams fuse into a single piece of material, which makes them stronger than the surrounding membrane when welded correctly.
›Does TPO work in cold climates?
It does. TPO stays flexible in freezing temperatures and handles thermal cycling well. We install it year-round, adjusting welder settings for ambient conditions.
›Does ARCM Roofing warranty TPO installation?
Yes. Our labor warranty covers the installation — 3 years on commercial systems, 10 years on residential low-slope — and certified installation qualifies for No-Dollar-Limit manufacturer warranties up to 20 years.
