TPO Roofing & Deck Waterproofing Systems
Our TPO roofing category covers professional Thermoplastic Polyolefin (TPO) membrane installations for residential and light commercial applications where long-term waterproofing is critical. TPO is an ideal solution for flat and low-slope roofs, balconies, and decks built over conditioned living space, providing a fully heat-welded, watertight membrane with proven durability.
We specialize in deck-over-TPO assemblies, including the proper installation of non-penetrating sleeper systems above the membrane. This allows homeowners to install walkable deck surfaces—such as composite decking, pavers, or porcelain tile—without compromising the waterproofing below. All systems are designed with proper slope, drainage, and membrane protection to ensure long-term performance.
This category includes real project examples, technical guidance, and best practices for:
