What Is TPO Roofing?
Thermoplastic Polyolefin (TPO) is one of the most popular single-ply roofing membranes for flat and low-slope roofs. It combines the durability of EPDM rubber with the heat-welded seam strength of PVC, making it an excellent choice for commercial buildings, additions, and modern flat-roof homes.
TPO’s white reflective surface is especially effective in Sacramento’s hot climate — reducing cooling costs by reflecting UV rays rather than absorbing them.
Benefits of TPO Roofing
Energy Efficient
White reflective membrane significantly reduces heat absorption, lowering cooling costs in Sacramento’s hot summers.
Strong Seam Welds
Heat-welded seams are stronger than the membrane itself, virtually eliminating seam failures and leaks.
Chemical & Algae Resistant
TPO resists UV radiation, ozone, and chemicals, maintaining performance and appearance over time.
Cost-Effective
TPO offers excellent performance at a lower cost than PVC, making it a popular choice for budget-conscious commercial projects.
Lightweight
TPO membranes are lightweight and easy to install, reducing labor time and structural load on the building.
Long Lifespan
Properly installed TPO systems typically last 20–30 years with minimal maintenance.
