Modern TPO Roofing Meets Historic Charm in SW Portland, Oregon

Expert TPO Roof Installation by Project Manager Ki Jayne on Historic SW Portland Home

Our team, led by Project Manager & Estimator Ki Jayne, recently completed a high-performance 60-mil TPO roofing system on a stunning historic 1910 home in SW Portland, Oregon. The original deck had aged significantly, requiring a long-lasting, energy-efficient roofing solution to safeguard the home’s structural integrity.

Project Highlights & Precision Installation

System Installed: Slate Grey GAF 60-mil TPO Membrane (a premium single-ply roofing system)

Installation: Ki Jayne installed this project himself ensuring meticulous attention to detail from estimation to final execution

Enhanced Roof Assembly:

1” ISO board insulation mechanically fastened for superior thermal performance and stability

Hand-welded TPO seams and custom flashings for a watertight, durable seal

Weatherproofing Reinforcements:

Termination bar secured with rubber washer screws along siding edges

Epoxy-based liquid rubber applied at termination bar seams as an extra defense against wind-driven rain

Why This Roofing Solution Matters

Energy Efficiency: TPO’s high solar reflectance reduces heat absorption, helping the home stay cooler in summer and retain warmth in winter—lowering energy costs.

Long-Term Protection: The UV-resistant TPO membrane and ISO insulation extend the roof’s lifespan while defending against Portland’s rain and temperature swings.

Preventative Measures: Ki Jayne’s strategic use of liquid rubber epoxy and welded seams ensures maximum moisture resistance, preventing future leaks.

With Ki Jayne’s expert installation, this project not only restored the home’s roof but optimized its performance and durability, blending modern technology with the home’s historic charm.
