Single-Ply Membrane Roofing
The Modern Standard for Low-Slope Roofs
Single-ply membrane is the most popular category of commercial roofing for a reason: a single, factory-made sheet of TPO, EPDM, or PVC delivers proven waterproofing with less weight and faster installation than older multi-ply systems. At Guardsmen Commercial Roofing, we install and service all three single-ply membranes to manufacturer spec, then help you pick the right one — and the right attachment method — for your building, climate, and budget.
Why Choose Single-Ply
Lightweight on Your Structure
A single membrane adds far less weight than built-up or modified systems, easing the load on your roof deck.
Energy-Efficient Options
Reflective white TPO and PVC bounce back the Georgia sun, lowering rooftop temperatures and cooling costs.
Fast, Clean Installation
Wide factory sheets and welded or adhered seams install quickly with minimal disruption to your operations.
Three Proven Membranes
TPO, EPDM, and PVC each have decades of field history, so you're choosing from time-tested, reliable systems.
Flexible Attachment
Mechanically fastened, fully adhered, or ballasted — we match the attachment method to your building and wind exposure.
Dependable Waterproofing
Welded or sealed seams create a continuous watertight surface engineered for flat and low-slope roofs.
How We Install Single-Ply Membrane
1 · Assess & Recommend
We inspect your roof and recommend the right membrane and attachment method for your structure and goals.
2 · Prep the Substrate
We tear off or prep the existing roof, repair the deck, and install insulation and cover board to spec.
3 · Install the Membrane
We mechanically fasten, adhere, or ballast the membrane, then weld or seal every seam watertight.
4 · Detail & Inspect
We finish all flashings and penetrations, inspect every seam, and register your manufacturer warranty.
The Three Single-Ply Membranes
Single-ply isn’t one product — it’s three. TPO offers reflectivity and value, EPDM brings a 40-year durability track record, and PVC leads on chemical and grease resistance for restaurants and plants. Each is a smart choice on the right building. Compare them in depth on our TPO, EPDM, and PVC pages, or see all options on the roofing systems hub →
| Feature | TPO | EPDM | PVC |
|---|---|---|---|
| Surface | Reflective white | Black | Reflective white |
| Seam method | Heat-welded | Taped / adhered | Heat-welded |
| Energy efficiency | High | Low | High |
| Chemical / grease resistance | Good | Fair | Excellent |
| Relative cost | $$ | $ (lowest) | $$$ |
| Typical lifespan | 20–30 yrs | 30–40 yrs | 20–30 yrs |
Choosing the Right Membrane & Method
The best single-ply system depends on your slope, energy goals, chemical exposure, and budget — and the right attachment method depends on your deck and wind zone. That’s exactly the kind of honest guidance our free inspection provides: we’ll tell you which membrane and method genuinely fit your building, not just whichever we’d rather sell.

FAQ
Single-Ply Roofing — Common Questions
Single-ply is a category of commercial roofing made from a single factory-produced sheet of synthetic material — TPO, EPDM, or PVC — installed over insulation on low-slope and flat roofs. It’s lighter and faster to install than older multi-ply systems and is the most widely used commercial roofing category today.
It depends on your building. TPO offers reflective energy efficiency at a good price, EPDM is extremely durable and economical, and PVC excels where grease or chemicals are present. We assess your roof and recommend the right fit rather than pushing one product.
There are three common methods: mechanically fastened (screwed down through plates), fully adhered (glued to the substrate), and ballasted (held down with stone or pavers). We choose the method based on your deck type, slope, and wind exposure.
Depending on the membrane, thickness, and maintenance, single-ply roofs typically last 20 to 40 years. EPDM is on the longer end, while TPO and PVC commonly run 20 to 30 years. Proper installation and regular maintenance maximize lifespan.
Often yes, depending on the condition of your current roof and local code. We inspect the deck and existing system first to determine whether a recover or a full tear-off is the better long-term choice for your building.
