TPO Roofing Installation
ENERGY-EFFICIENT | LICENSED CA #987654

TPO roofing installation addresses commercial flat roof waterproofing requirements where energy efficiency and long-term performance justify single-ply membrane systems. We install thermoplastic polyolefin membranes with heat-welded seams on commercial buildings, and repair punctures, seam failures, and shrinkage issues on existing TPO roofs. This single-ply system provides 20-30 year service life with reflective white surface reducing cooling costs.

When TPO Roofing Applies

TPO roofing installation is appropriate when:

• Commercial flat or low-slope roofs require energy-efficient white reflective surface
• Building codes mandate cool roof compliance for California Title 24 energy standards
• Heat-welded seam strength exceeds adhesive or mechanically-attached systems
• Chemical resistance needed for restaurant grease, oils, or industrial exposure
• Budget supports premium single-ply membrane with 20-30 year manufacturer warranties
• ENERGY STAR certification contributes to LEED points or utility rebates

When TPO Roofing Does NOT Apply

TPO roofing may not be suitable for:

• Steep-slope applications where shingle or tile systems perform better
• Roofs with extensive ponding water requiring improved drainage before membrane installation
• Substrate conditions with wet insulation or structural deficiencies requiring correction
• Budget constraints limited to economy built-up or modified bitumen systems
• Installations requiring petroleum-based product compatibility (TPO degrades with certain oils)
• Extremely cold climates where TPO becomes brittle below manufacturer specifications

Our TPO Roofing Evaluation

Our inspection and evaluation process assesses:

• Substrate condition: Infrared moisture scans to detect wet insulation requiring replacement
• Drainage analysis: Slope verification and ponding water assessment for positive drainage
• Deck integrity: Structural capacity for new membrane and insulation system weight
• Attachment method: Mechanical fastening, fully-adhered, or ballasted system determination
• Penetration count: HVAC units, vents, drains, and equipment requiring flashing details
• Code compliance: Fire rating, wind uplift, and energy efficiency requirements verification

Materials and System Options

TPO membrane specifications depend on building requirements and performance criteria:

• Membrane thickness: 45 mil, 60 mil, or 80 mil based on traffic exposure and warranty requirements
• Mechanically-attached: Fastener plates with overlapping seams for cost-effective installation
• Fully-adhered: Complete bonding to substrate for maximum wind uplift resistance
• Ballasted systems: River rock or pavers over loose-laid membrane where structure permits
• Insulation options: Polyiso, EPS, or XPS to achieve required R-value for energy codes

Outcomes and Expectations

TPO roof service life and performance characteristics:

• Service life ranges 20-30 years with proper installation and annual maintenance inspections
• Heat-welded seams create watertight bonds stronger than membrane tensile strength
• White reflective surface reduces cooling costs 20-40% versus dark-colored roofing
• Membrane shrinkage normal during first year; excessive shrinkage indicates installation defects
• Puncture resistance varies by thickness; foot traffic and equipment placement require walk pads
• UV degradation occurs over time; chalking and discoloration don't affect waterproofing performance
• Manufacturer warranties require approved contractors and annual maintenance documentation
