Our TPO Roofing Services
TPO Roof Repairs
Our crews handle TPO repairs using professional hot-air welding equipment to reseal failed seams, patch punctured membrane, and replace deteriorated flashing around HVAC curbs, vents, and drains. We address the issues that commonly affect TPO in Arizona's climate like seam separation, penetration failures, and flashing problems. Most repairs can be completed in a single visit with full photo documentation for your records.
TPO Roof Installation
New TPO installation starts with proper deck preparation—cleaning, priming, and making sure the substrate is ready to receive the membrane. We install polyiso insulation for thermal performance, then mechanically fasten or fully adhere the TPO membrane depending on building requirements and wind uplift calculations. Every seam is heat-welded and tested for integrity. We also install edge metal, termination bars, and flashing around every penetration.
TPO Inspections & Maintenance
Full replacement includes tear-off of the old membrane and insulation, deck inspection, and installation of a completely new TPO system. Projects often include slope corrections to eliminate ponding water and upgraded insulation for better energy performance. We coordinate with property managers to minimize tenant disruption and keep the building protected throughout the process.
TPO Roof Replacements
We walk the entire roof surface, check every seam with a probe test, inspect flashing and edge details, and look for early signs of membrane degradation. Drain clearance is part of every visit. You get a written report with photos, findings, and recommended actions. We also offer annual maintenance contracts for property managers who want to stay ahead of problems.
Our Process & What to Expect
Once you reach out, we schedule a roof inspection at a time that works for your team. Our process is straightforward—no pressure, no vague estimates.
- Full Roof Inspection & Documentation We walk the entire roof, check every seam, inspect flashing and edge details, and test for moisture intrusion. You get a written report with photos within 48 hours.
- Repair vs. Restore vs. Replace We’ll tell you honestly what your TPO roof needs. If a seam repair solves the problem, that’s what we recommend. If the membrane is failing across the board, we’ll explain why replacement makes more sense than patching.
- Project Timeline & Communication For larger jobs, we coordinate scheduling, tenant notifications, and site access. You get a dedicated project contact who keeps you updated throughout the work.
- Warranty Options Most TPO installations include manufacturer material warranties and our workmanship warranty. We’ll walk you through what’s covered and for how long before any work begins.

What Phoenix TPO Roofs Face
TPO membranes are built for heat and UV exposure, but Arizona pushes every material to its limits. The roofs we inspect across the Valley show the same patterns of wear—and most of it comes down to how the climate attacks specific weak points.
- Extreme UV Exposure Arizona’s sun degrades plasticizers in TPO membrane over time. We see brittleness and surface cracking by year ten or twelve, especially on thinner 45-mil or 50-mil installations.
- Thermal Expansion Stress on Seams Daily temperature swings of 40–50°F put constant stress on welded seams. Over thousands of cycles, seams that weren’t welded correctly start pulling apart—the most common TPO failure we see in Phoenix.
- Monsoon Wind and Storm Damage Summer storms lift membrane edges, back out fasteners, and tear flashing loose around equipment curbs. Hail punches through aged membrane that’s lost its flexibility.
- Dust Accumulation and Drainage Issues Dust storms clog drains and scuppers, causing ponding water that accelerates membrane breakdown. A roof with blocked drains holds water for days—and standing water degrades TPO faster than direct sun.
Why TPO Roofs Fail in Arizona
Most TPO failures we see aren’t from the membrane wearing out naturally—they’re from installation shortcuts, wrong specs, or deferred maintenance. Arizona’s climate doesn’t forgive mistakes that might go unnoticed in milder regions.
- Common Installation Mistakes Seam welding is where most problems start. Welds done too fast, too slow, or at the wrong temperature fail within a few years. We also see wrong adhesives, underspecified membrane thickness for the building’s use, and skipped flashing details around penetrations.
- Warning Signs Property Managers Miss Bubbling or blistering in the membrane, visible seam separation, soft spots when walking the roof, and interior water stains that seem minor. By the time water shows up inside, the insulation underneath is often already saturated.
- Deferred Maintenance Issues Skipping annual inspections lets small problems grow. A seam that could’ve been re-welded for a few hundred dollars turns into a full replacement when water sits underneath for two years. Clogged drains that take five minutes to clear cause thousands in damage when ignored.
TPO Roofing Systems We Install
Not all TPO is the same. Membrane thickness, attachment method, and manufacturer quality all affect how long the roof lasts in Arizona’s climate. We install systems from the major commercial roofing manufacturers and help property owners choose the right specs for their building.
- Membrane Thickness Options: 45-mil TPO is the economy option, but it degrades faster under Arizona UV—we generally don’t recommend it for most applications. 60-mil is the standard commercial thickness and offers a good balance of durability and cost. 80-mil is the heavy-duty choice for high-traffic roofs, industrial facilities, and owners who want maximum lifespan.
- Attachment Methods: Mechanically fastened systems use plates and fasteners through insulation into the deck—faster installation with good wind uplift resistance. Fully adhered systems glue the membrane directly to insulation or substrate, giving a cleaner look with fewer penetrations. Fully adhered works better for high-wind zones and buildings with interior humidity concerns.
- Manufacturers We Work With: We install TPO systems from GAF, Carlisle, Firestone, Johns Manville, Versico, and Mule-Hide. Each has different warranty structures and product specs—we help you match the right system to your building and budget.

FAQ’s
Questions? We’re Glad that you asked!
How long does a TPO roof last in Arizona?
A properly installed TPO roof typically lasts 15–25 years in the Phoenix climate. Membrane thickness, seam quality, and regular maintenance all affect lifespan. Thinner 45-mil membranes tend to degrade faster under Arizona’s intense UV exposure than 60-mil or 80-mil options.
What causes TPO seams to fail?
Most seam failures come from improper welding during installation—temperature too high, too low, or inconsistent speed. Arizona’s daily thermal cycling puts extra stress on seams, so weak welds that might last elsewhere fail faster here.
How much does TPO roofing cost in Phoenix?
TPO roofing costs vary based on roof size, membrane thickness, attachment method, and building complexity. Most commercial TPO installations run between $5–$9 per square foot installed. We provide free estimates with detailed breakdowns after inspecting your roof.
Can you install TPO over an existing roof?
In some cases, yes. If the existing roof is in decent condition and local codes allow it, we can install TPO over certain substrates. However, if there’s moisture damage or saturated insulation underneath, tear-off and full replacement is the better long-term investment.
How often should a TPO roof be inspected?
We recommend annual inspections, plus an additional check after monsoon season. Catching small seam separations, clogged drains, or flashing issues early prevents expensive repairs down the road.
