Community Center Sloped Roof Project in Suttons Bay, MI

Project Overview

Springfield Roofing completed a custom sloped roof installation in Michigan for a community civic center that serves as a central hub for health, wellness, and community life. The facility supports physical fitness, community events, and wellness activities, and plays a vital role in encouraging healthy living among community members.

What makes this custom sloped roof installation especially unique is the building’s design itself — a distinctive, multi-faceted, curved architecture rooted in cultural symbolism meaningful to the community it serves. Early in the project, the team discussed the option of a single-color membrane to reduce cost, but a dual-color, patterned finish was ultimately chosen to keep the roof true to the design intent and cultural significance of the building. The curved rooflines and varied elevations required custom solutions, detailed planning, and close collaboration between Springfield’s team, Duro-Last, and the client over the course of more than a year. Springfield was the only contractor willing to be involved in the planning and design process from the outset, in addition to submitting a bid.

The Challenge

Delivering a custom sloped roof installation of this scale in Michigan called for a carefully staged, highly specialized approach:

  • Safe Access and Staging. Two 150′ man lifts were deployed to safely reach and navigate the structure’s varied elevations and curved rooflines.
  • Deck Preparation. All roof debris was cleared and loose metal decking re-secured to ensure a sound foundation for the new system.
  • Custom Insulation System. Custom-cut EPS styrene flute filler insulation was installed to contour the building’s unique ribbed roof deck, followed by one layer of 1½” polyisocyanurate insulation (R-8.6) for improved energy efficiency.
  • Membrane Installation. A 50 mil terra cotta Duro-Last™ membrane was hot-air welded and mechanically fastened across the roof for superior waterproofing, with an optional shell pattern available to complement the building’s design.
  • Enhanced Fasteners. Black double-coated fasteners, built to twice the industry standard, were used to meet Duro-Last specifications for deck penetration and long-term durability.
  • Edge Detailing. A 24-gauge vinyl-coated metal edge flashing was installed and hot-air welded to the membrane, creating full perimeter waterproofing.
  • Snow Fence Reinstallation. The existing snow fence system was temporarily removed and expertly reinstalled in a fully watertight fashion.

Why A Sloped Metal Retrofit Was The Right Choice

The building’s curved, multi-faceted form ruled out a standard, off-the-shelf roofing approach – a custom sloped roof installation was the only way to meet both the technical and design requirements of the project. A custom-fit insulation and membrane system allowed the team to follow the building’s unique contours precisely while still delivering the performance and waterproofing integrity of a standard Duro-Last system. Retaining the dual-color, patterned membrane preserved the architectural and cultural intent of the design, proving that a technically demanding, highly custom roof could be achieved in Michigan’s climate without compromising on aesthetics or long-term performance.

The Results

Following a final inspection by both Springfield’s team and the Duro-Last manufacturer, the completed roof system was issued a full 15-year manufacturer’s warranty. The project stands as one of the more architecturally complex roofs Springfield has completed, and the team was proud to deliver a solution that respects the building’s design significance while enhancing its long-term durability and performance for the community it serves. Additionally, Springfield was awarded the 2025 Duro-Last Specialty Membrane Project of the Year for this re-roof project.
