Project Overview: Christian Homes — Duro-Last TPO + 3" ISO (Holdrege, NE)
This project completed a targeted low-slope roofing scope for Christian Homes in Holdrege, Nebraska, covering
a total surface area of 515 sq. ft. The work included installing a Duro-Last TPO membrane
and adding 3" ISO insulation to support improved roof performance and a clean, professional finish.
Scope & Installation Planning
Even on smaller roof areas, long-term performance comes down to details: clean substrate prep, consistent insulation placement,
and watertight transitions at edges, penetrations, and terminations. This scope was planned to keep the work area controlled,
maintain clean site conditions, and deliver a finished roof system that’s built to perform—not just “pass inspection.”
- Verify the work area and roof conditions to confirm tie-ins and transition points.
- Install 3" ISO insulation to support the membrane system and improve overall roof assembly performance.
- Install Duro-Last TPO membrane with clean, consistent seams and detail work.
- Finish terminations and edge conditions for a watertight, long-lasting closeout.
Why ISO + TPO Works Best as a System
Adding ISO isn’t just about R-value—it helps create a flatter, more consistent surface for the membrane and supports better
long-term performance. When insulation and membrane are installed as one coordinated system, you reduce weak points and improve
durability at the details.
- More consistent roof plane for clean installation and better drainage behavior.
- Stronger overall assembly when transitions and terminations are handled with intent.
- Detail-forward finishing around edges and penetrations to reduce future leak risk.
- Cleaner closeout with a professional look and controlled jobsite standards.
Results & Takeaways
The finished work delivers a clean, watertight low-slope roof area with a Duro-Last TPO membrane and 3" ISO insulation,
helping support dependable performance and a professional closeout. The focus remained on correct transitions, clean detail work,
and a controlled jobsite—so the roof area is built for long-term confidence.
