Project Profile: Retail Facility
Location:Steubenville OH
Facility Type: Large Retail Building
Project Type: Cold Weather Tear-Off & Full Roof Replacement
Size:39,000sqft
System: Staggered ISO Insulation + 6-mil Vapor Barrier + Tan Duro-Last Membrane
Completion: Winter Install
Warranty: 20-Year NDL Material & Labor Warranty
Project Overview
This cold-weather roofing project involved a complete tear-off and replacement for a large commercial retail building in Southern Ohio. Code requirements called for a full system upgrade, meaning our team needed to remove the existing roofing down to the bare B-decking and rebuild the system from the deck up—all while navigating the logistical and material challenges of a winter install.
We engineered a layered insulation and vapor barrier solution designed to meet R-25 energy code requirements while preventing condensation issues that can plague cold-weather roofing projects. A high-performance tan Duro-Last single-ply membrane capped off the system, delivering lasting protection and energy savings.
Scope of Work
Complete Roof Tear-Off
- Stripped all existing roofing materials down to the B-decking
- Inspected and prepped deck for new insulation system
Insulation & Vapor Barrier Assembly
- Installed first layer of 2.2” ISO insulation, staggered joints for maximum thermal performance
- Rolled out 6-mil vapor barrier to block warm air from penetrating insulation layers
- Applied second layer of 2.2” ISO, staggering joints for R-25 compliance
- All penetrations and curbs sealed with spray foam to ensure airtightness
Membrane Installation
- Installed tan Duro-Last single-ply membrane, ideal for visibility and solar reflectivity
- Heat-welded seams and precision detailing around all penetrations
- Delivered a finished system warrantied for 20 years NDL (no dollar limit)
Challenges & Solutions
Challenge
- Cold weather install with condensation risk
- Retail building with operating hours and public access
- Code-compliant energy performance in a winter install
Solution
- Engineered a double-layer insulation system with integrated vapor barrier to mitigate warm air intrusion and condensation risk
- Sequenced work to avoid business disruption; maintained site cleanliness and public safety throughout
- Designed R-25 system using staggered ISO and airtight detailing; verified proper fastening and seal integrity in cold conditions
Results & Value
Despite the cold temperatures and tight timelines, this project was completed on time, to spec, and with zero disruption to the client’s retail operations. The custom-designed insulation and vapor barrier assembly ensures lasting thermal performance, while the tan Duro-Last membrane offers aesthetic appeal and energy efficiency for the long term.
This retail property now has a durable, energy-efficient roofing system backed by a 20-year NDL warranty, with no compromise on performance—even in challenging conditions. It’s another example of how our team delivers precision and reliability year-round, no matter the weather.
