Single Ply

Long gone are the days of built up roofs and hot tar kettles. Current roofing materials are mostly single ply membranes, which means exactly that; one layer thick. They require specialized equipment to be able to install and weld, but are well worth it. They are lighter weight, easier to repair, and extremely energy efficient.

Commerical Roofing Stories

Hamstra's Revitalization of the Historic Caterpillar Equipment Plant in Joliet, Illinois

Hamstra takes center stage in the architectural preservation scene with its latest project, the roof restoration of the iconic old Caterpillar equipment plant in Joliet, Illinois. On a chilly November morning, our team, led by our commercial project manager Tim Shankle, embarked on a meticulous journey to replace the aged roofing system of this historic structure. The project began with an in-depth assessment of the existing tar and gravel roof, a testament to traditional construction methods.

  • Our approach integrates cutting-edge roofing technology with respect for the building's historical significance. We chose to install a Thermoplastic Polyolefin (TPO) roofing system, recognized for its superior durability, reflectivity, and environmental resistance. This choice underscores Hamstra's commitment to employing sustainable and high-performing materials in our restoration projects. A key step in our process involves laying a protective recovery board over the old roof, ensuring the TPO layer's optimal performance and longevity.

    The logistical planning and execution of this project, aimed to be completed in a 14-day timeframe, demonstrates Hamstra's prowess in managing complex restorations under challenging winter conditions. Our project not only highlights the technical aspects of modern roofing solutions but also our dedication to preserving the architectural heritage of industrial America. This restoration is a prime example of how Hamstra combines innovative construction techniques with a deep reverence for history, ensuring the Caterpillar equipment plant's legacy endures for generations to come.

Two Decades of Durability: Hamstra's Reflections on Roof Longevity and Efficient Replacement Strategies

Twenty years ago, Hamstra set a benchmark in the roofing industry by installing a roof that stood the test of time. Today, as we embark on the replacement of this very roof, we take a moment to reflect on the journey and the advancements in roofing technology that have shaped our approach.

  • The process of tearing off and replacing a roof is not just a technical challenge; it's a race against time to ensure water tightness and minimize risk. Our priority is the safety of our employees, the protection of pedestrians, and the assurance that the new roof will be leak-free from day one.

    By the third day of the project, significant progress had been made, and we were on track to complete the work within our projected timeline, showcasing our commitment to efficiency and excellence. Meeting with the owner on-site, we were reminded of the lasting relationships we build through our work, with the promise of quality that brings clients back, even after two decades. This project stands as a testament to Hamstra's enduring commitment to delivering roofing solutions that are not only durable but also executed with the utmost attention to safety and risk management.
