Celina High School PVC Roofing Project

PROJECT OVERVIEW

A fast-paced construction schedule and coordination across multiple trades called for a flexible approach to roofing installation at the new Celina High School in Celina, Ohio. Designed to serve students in grades 7 through 12, the new educational facility required a 132,744-square-foot roofing system that could be installed efficiently as construction progressed across multiple phases.

Cotterman & Company, Inc. (Cotterman) was tasked with installing an Elevate MAX™ PVC roofing system while navigating changing schedules, limited installation windows and ongoing construction activity. With multiple trades working simultaneously, careful coordination and timely access to roofing materials were essential to keeping the project moving forward.

THE CHALLENGES

With construction progressing in phases, Cotterman faced the challenge of installing a large-scale roofing system without access to the entire roof at once. Each newly available section presented a narrow installation window, requiring crews to mobilize quickly, complete the roofing work and dry in the area before interior construction could proceed.

The constantly evolving schedule required Cotterman to remain adaptable, adjusting crew sizes, coordinating material deliveries and responding to changing jobsite conditions. Close communication with the general contractor and other trades was critical to ensuring each section was ready for installation and completed without disrupting subsequent construction activities.

With little room for scheduling delays, Cotterman relied on its established relationships with Elevate and its distributor to secure materials as needed and keep installation moving, helping ensure the school would be ready for the upcoming school year.

ROOFING SYSTEM SOLUTION

Finding a roofing solution that would be dependable for quick application while delivering high, reliable performance was essential for Cotterman, leading the contractor to choose a 60 mil Elevate MAX PVC membrane. C&C’s long-standing distributor relationship and history with Elevate enabled the team to obtain roofing materials on short notice as timelines shifted.

The roof assembly included a loosely laid vapor barrier, followed by a mechanically fastened 2.5-inch layer of polyiso insulation. A second 2.5-inch polyiso layer was adhered using Elevate Twin Jet Y, followed by the MAX PVC membrane, which was also fully adhered using Twin Jet Y.

The wide-spatter application of Twin Jet Y provided consistent coverage and enabled a fast application, while its ability to adhere at lower temperatures expanded the timing windows for installation as different parts of the roof became available. The versatility of Twin Jet Y allowed Cotterman to reverse the typical installation sequence in certain areas, enabling smoother coordination with other trades across the project.

Material Choices

• 60 mil Elevate MAX PVC membrane for reliable performance

• Two 2.5 inch layers of polyiso insulation

• Elevate Twin Jet Y to adhere to the top insulation layer and MAX PVC

• Loosely laid vapor barrier

PERFORMANCE HIGHLIGHTS

“MAX PVC and Twin Jet Y gave us the flexibility we needed for a fast-paced project, and the timely support from both Elevate and our distributor helped us readily respond as the schedule changed,” said CJ Brookhart, Project Manager, Cotterman & Co. “Every part of the project worked hand in hand, which allowed us to meet the needs of the general contractor and keep the work moving.”

While construction of the full high school was not fully complete, the successful roofing system that Cotterman installed builds on its portfolio of work across other Celina City School District facilities. For Celina High School, Cotterman's experience, combined with timely service from Elevate, helped keep the project on track and deliver a high-performing, dependable system backed by a 20-year Elevate Red Shield Warranty.
