Rubber/TPO
Rubber and TPO Roofing for Flat and Low-Slope Structures
Single-ply membranes solve a problem that traditional shingles cannot handle: sealing a flat or low-slope roof against standing water, pooling, and constant sun exposure. Rubber, known in the industry as EPDM, and TPO, short for thermoplastic polyolefin, are two of the most reliable membrane systems available for these surfaces. At Beatty Construction & Roofing, we install both across commercial buildings, additions, and residential structures with roofs that shingles were never designed to protect.
These two materials share a purpose but differ in composition. EPDM is a synthetic rubber sheet, typically black, prized for its stretch and cold-weather durability. TPO is a white or light-colored thermoplastic sheet that reflects sunlight and reduces cooling loads. Choosing between them depends on your building, your energy goals, and your budget, and we walk you through that decision before any material arrives on site.
How the Two Membranes Differ
Understanding the technical distinctions helps you make an informed choice. Each system carries strengths that suit specific conditions, and matching the material to the structure is where long-term performance begins.
- EPDM rubber: Bonds with adhesive or is mechanically fastened, and seams are joined with tape or liquid adhesive. The rubber flexes without cracking in freezing temperatures and commonly lasts 25 to 30 years with proper care.
- TPO membrane: Seams are heat-welded, creating a bond as strong as the sheet itself. The reflective surface lowers rooftop temperatures, which cuts air conditioning costs during hot Virginia summers.
- Thickness options: Both membranes come in varying thicknesses, generally 45, 60, and 80 mil. Thicker sheets resist punctures and foot traffic better, an important factor for roofs that need regular equipment servicing.
- Insulation pairing: We install rigid insulation board beneath the membrane to meet energy codes and improve the finished roof’s R-value.
We review these specifications with you directly, because the right combination of material, thickness, and insulation depends on how your building is used and the climate loads it faces year-round.
Our Installation Process
Every membrane roof we install follows a disciplined sequence. We begin by tearing off the old roofing down to the deck, or in some cases installing over a sound existing surface when conditions allow. The deck is inspected for rot, soft spots, and moisture damage, and any compromised sheathing is replaced before we proceed.
Next, we lay the insulation and secure it according to the manufacturer’s fastening pattern. The membrane is then rolled out, positioned, and either adhered, fastened, or ballasted depending on the system. For TPO, we heat-weld every seam and test the welds for a complete bond. For EPDM, we tape and roll the seams to guarantee a watertight join. Flashing details around vents, curbs, drains, and edges receive extra attention, since these penetrations are where most leaks begin. When the work is finished, we perform a final inspection to confirm the entire surface drains correctly and every seam holds.
Where Membrane Roofing Fits Best
Rubber and TPO serve a wide range of structures throughout Virginia Beach, VA. Warehouses and distribution centers with expansive flat roofs benefit from the seamless coverage and low maintenance these systems provide. Retail storefronts and strip centers often choose TPO for its reflective surface, which trims energy expenses across large footprints.
On the residential side, we frequently install these membranes on home additions, sunroom roofs, porch covers, and modern flat-roof designs where shingles would trap water. Restaurants, medical offices, churches, and light industrial buildings also rely on single-ply roofing for its predictable performance and long service life. Whatever the application, Beatty Construction & Roofing matches the membrane to the demands of the structure and the expectations of the owner.
Service, Repair, and Emergency Response
A membrane roof still needs attention over its lifespan. Punctures from fallen branches, seam separation from age, and damage around rooftop equipment can all let water in. We repair EPDM and TPO roofs by cleaning the affected area, applying compatible patch material, and re-welding or re-adhering the surface so the repair blends into the original system.
When a storm tears open a seam or a leak appears without warning, waiting is not an option. That is why we offer 24/7 emergency service, so a sudden failure never leaves your building exposed. As a family-owned and operated company, we treat every roof as if it were on our own home, and our reputation is built on trust and backed by quality. When you call Beatty Construction & Roofing for rubber or TPO work, you get a licensed team that stands behind every seam we weld and every sheet we lay.
