Heat-Welded Watertight Seams
TPO sheets are joined with hot-air welding, forming strong, continuous seams that resist leaks and provide dependable protection against wind-driven rain on low-slope roofs.

TPO Roofing Lake Oswego
TPO (thermoplastic polyolefin) has become one of the most widely installed membrane systems for flat and low-slope roofs, and for good reason. Its heat-welded seams fuse into a single continuous surface rather than relying on adhesives alone, its reflective finish helps manage rooftop heat, and it holds up well against UV exposure and the foot traffic that comes with servicing rooftop equipment.
We install and repair TPO roofing for commercial buildings and low-slope residential sections throughout Lake Oswego. For the broader category of low-slope systems, see our flat roof installation page, or talk with our team about whether TPO is the right membrane for your roof.

TPO Roofing in Lake Oswego
Reflective Energy-Saving Surface
The light-colored membrane reflects sunlight and reduces heat absorption, which can lower cooling demand and help moderate building temperatures during warm months.
Cost-Effective Single-Ply Solution
TPO often delivers strong performance at a moderate price, making it a popular choice for commercial buildings and modern residential flat roofs where budgets matter.
Resistance to Common Roof Stressors
The membrane resists UV exposure, mildew, punctures, and many chemicals, helping it stand up to Oregon's weather and the wear that comes with regular rooftop access.
Lightweight Installation Options
TPO can be mechanically attached, fully adhered, or ballasted depending on the structure. Its lighter weight often avoids the need for added structural reinforcement.
Repair-Friendly Membrane
Punctures and seam issues can be patched cleanly with compatible materials, allowing quick, targeted repairs that keep maintenance costs reasonable throughout the roof's service life.
Why Choose Our TPO Roofing in Lake Oswego
TPO is a popular choice for commercial and low-slope roofs because it’s reflective, energy-efficient, and resistant to ponding water when installed correctly. Installation quality is everything. Our crews heat-weld every seam, detail every penetration carefully, and design drainage so water moves off the roof. We coordinate around your business operations and finish with a thorough inspection. Lake Oswego building owners choose us for dependable TPO systems backed by manufacturer and workmanship warranties, so the roof stays quiet and leak-free.
Is It Right for You?
When TPO Roofing Makes Sense
You Operate a Commercial or Retail Building with a Flat Roof
TPO is one of the most widely used membrane systems on commercial low-slope roofs, prized for its balance of cost, durability, and installation speed.
You Want a Reflective Roof to Help Offset Summer Heat Gain
TPO's light-colored surface reflects sunlight rather than absorbing it, which can help moderate rooftop and interior temperatures during warmer months.
Your Existing EPDM or Built-Up Roof Is Failing
Aging seams, ponding, or repeated leaks on an older membrane system are common reasons building owners switch to a newer TPO installation.
You Need a Roof Rated for Regular Rooftop Foot Traffic
TPO handles the foot traffic that comes with servicing rooftop HVAC units and other equipment better than many older membrane types.
A Reflective, Reliable Membrane
Benefits of TPO Roofing For Lake Oswego Buildings
TPO is a popular membrane for commercial and low-slope roofs because it is reflective, energy efficient, and built to resist ponding water when installed correctly. Here is what Lake Oswego building owners gain from choosing a TPO roof system.
- Reflective white or light-colored membrane that helps manage rooftop heat
- Heat-welded seams create a strong, continuous waterproof surface
- Lighter weight than some other low-slope roofing systems
- Resistant to UV exposure, punctures, and most chemical exposure
- Well suited to large, open commercial roof areas
- Can sometimes be installed over an existing low-slope roof system
Our TPO Roofing Installation Process
Roof Assessment & System Selection
We evaluate the existing roof and building needs to confirm TPO is the right membrane choice, including thickness and attachment method.
Insulation Board Installation
Insulation board is installed and fastened or adhered to the deck, providing both thermal performance and a stable base for the membrane.
Membrane Roll-Out & Heat-Welded Seaming
TPO sheets are rolled out across the roof and seamed together using hot-air welding equipment, fusing adjoining sheets into a single continuous membrane.
Flashing & Penetration Detailing
Every roof penetration, drain, and edge is flashed and welded according to manufacturer specifications, since these details matter as much as the field membrane itself.
Final Inspection & Seam Testing
We check seam integrity across the finished roof and walk the completed installation with you before considering the project complete.

TPO Roofing FAQs
TPO seams are heat-welded into one continuous sheet, while EPDM seams are typically glued or taped, which some building owners consider a weaker long-term seal. TPO is also reflective and light-colored, where EPDM is usually black and absorbs more heat.
Its reflective surface reduces how much heat the roof absorbs compared with a dark membrane, which can help moderate rooftop and top-floor temperatures, particularly on buildings with significant roof area.
Sometimes, depending on the condition of the current roof and local code requirements. We assess the existing system during your estimate and recommend a tear-off if it's the better long-term option.
TPO panels are heat-welded using hot-air equipment that fuses the material together into one continuous membrane, rather than relying on adhesives or tape the way some older systems do.
TPO is most common on commercial low-slope roofs, but it's also a solid option for residential additions, garages, or other low-slope sections of a home. Our flat roof installation page covers how it fits alongside other low-slope options.
