Project Overview
An internationally recognized manufacturer of flooring solutions expanded its distribution center in Garland, Texas. The company added an additional 60,000 square-foot space to its existing 180,000 square-foot warehouse facility, increasing capacity for finished goods. Centimark Corporation, a nationwide roofing contractor in business since 1968, was selected to install the new roof system.
Challenges
The Northern Texas region experiences severe weather throughout the year. In the spring, the region is prone to supercell thunderstorms that can produce large hailstones. Temperatures can reach over 100 degrees Fahrenheit in the summer. Centimark’s customer required an energy efficient and durable roof system to provide premium coverage for its second largest distribution center.
The Roof System Selected
Centimark selected a multi-ply modified bitumen (mod bit) roof system. The two-ply mod bit system consists of Polyglass’ Elastoflex SA V self-adhered SBS base sheet and Polyfresko® G SA, a highly-reflective white granulated self-adhered APP cap sheet. For insulation, 4″ Polyisocyanurate was mechanically attached to the roof’s steel deck.
Polyfresko G SA provides the reflectivity required to consistently reduce the interior temperature of the building. In addition, Polyfresko G SA is listed with the Cool Roof Rating Council (CRRC®) and has an initial SRI of 96. Polyfresko G SA also features patented CURE Technology®, a thin film technology that ensures the membrane will maintain its bright white surface.
The Polyglass self-adhered system was appealing for this project because of the quick installation time and the ability to address the details around the many roof penetrations. Another contributing factor to the decision is the long-term performance of a Polyglass multi-ply system. Read more about this project in Western Roofing Magazine (Nov./Dec. 2016 issue)
About the Project
The La Gorce Palace Condos, with its distinct dark blue glass tower, is a high-end residential property located in Miami Beach, Fla. Designed by Schapiro Associates, the 34 story luxury condominiums were built in 1996 on prestigious Collins Avenue overlooking the Atlantic Ocean.
La Gorce Palace Condominium Association selected roofing contractor Building Unlimited, Inc. (since acquired by Miami, FL-based Isaacs Roofing) to tear off and reroof the 12,000 square foot roof.
Challenges
Collins Avenue is an international tourist destination with its beautiful ocean front hotels, popular white sand beaches and world-renowned dining and shopping options. A busy location, the project was not conducive to utilizing construction equipment that could potentially interfere with traffic. As a result, materials were transported to and from the roof in freight elevators.
The Roofing System Selected
The previous roofing system was removed down to the structural concrete deck. The new Polyglass self-adhered modified bitumen roofing system consisted of two layers of Elastoflex SA V SBS membrane and Polyflex® SA P granulated cap sheet. The three-ply roofing system featuring Polyglass’ patented ADESO® Self-Adhered Technology was installed over tapered polyisocyanurate insulation.
The Polyglass roofing system was selected based on project conditions and the building owner requirements. Critical project specifications included the following:
• Wind design pressure requirements for a high-rise building in a hurricane zone
• Minimal equipment for installation
• Speed of installation
• Reduced waste
• Durable multi-ply system backed by Polyglass’ 20-year roofing system warranty
Major renovations were done to this high end shopping center – home to some of the world’s finest retailers.The Waterside Shops at Pelican Bay is home to retailers including Cartier, Gucci, Louis Vuitton and Burberry, to name a few.
With over $22 million of renovations at stake, the developer knew the importance of utilizing quality materials. While there are several underlayment options in the market, Waterside’s challenge was to find a membrane that could be exposed to the elements for a long period of time without immediately installing the roof after the application. After examining a variety of underlayment products, Nu-Tec opted to use Polyglass’ Polystick TU Plus underlayment for the project.

The warehouse building was flat with an awning in the back displaying a 2:12 pitch. The office section was in the front of the building and the main section of the warehouse had 20-foot open ceilings. It was a large installation that needed to finish on tight deadlines. Novakovich Enterprises, Inc. was up for the challenge.
The contractor installed Polyglass’ Polyflex®, an APP torch down modified bitumen base sheet and Polyflex® G APP granulated cap sheet over the existing membrane. Though not required, the crew covered the cap sheet with an aluminum coating. The coating enhanced the roofing system with extra protection.

The 9,800-square-foot addition project called for a self-adhered, modified bitumen roofing material that the city of Seattle had often used in the past. However, the specified material was quite costly, leading everyone to search for an alternative.
After considering a number of options, the project’s roofing contractor, SQI Inc., decided on PolyKool®, a highly reflective, modified bitumen roofing membrane that is part of Polyglass’ KOOL ROOF SOLUTIONS. PolyKool is an APP-based, modified bitumen membrane that utilizes Polyglass’ patented ADESO® Dual-Compound Self-Adhered Technology.

This high profile job was one of two jobs completed at the time for the University of Hawaii Law School. The 1,500 square foot roof was in need of replacement. Having minimal disruption to the law students utilizing the library to study was critical to the job. After the tear off all the way to the concrete roof deck, a layer of Polyglass APP Base was applied, followed by Instastik applied EPS insulation Securock cover board, two plies of Elastoflex SA V base sheet and Polyflex® G FR in white.
The project was completed in record time and the result is a roof that will protect the library and its occupants for years to come.
