Roofing Contractor Ainger Group upgrade the roof of 20 homes on the Canadian Air force Base in Trenton, Ontario. Polyglass’ Elastoflex SA P Gray Slate, a self-adhered cap sheet was selected for the 400 sq.ft. flat part of the roofs. The cap sheet was a perfect match for the shingles and are available in 10 colors.
Project Type: Commercial
Lynnwood Senior Living
Project Overview:
Roofing Contractor 3-D Roof System installs Polyglass’ Vegetative Roof atop the SHAG (Senior Housing Assistance Group) Lynnwood, Wash. property. Backed by a 30-year warranty, the three-ply modified bitumen system chosen provides the critical waterproofing needed for a vegetative roof assembly. At 500-mils thick, the system adds layers of defense for the roof and enables long-term performance. In comparison, singly ply membranes typically have a 60 mils total thickness.
Products include two layers of Polyglass’ Polyflex® Smooth APP (Atactic Polypropylene) modified bitumen membrane for the base and interply sheets. For the final layer, Polyflex® G White APP cap sheet was installed to provide resistance to punctures, tears, abrasion, foot traffic and the elements. Elastoflex SA V—a high performing self-adhered membrane featuring Polyglass’ ADESO® Technology was used for the flashing details.
Challenges:
3-D Roof Systems began the roof installation in October 2016, which according to the Seattle Times had record breaking rainfall. But 3-D Roof Systems was prepared for the inclement weather. The team used a system of inflatable tenting adapted for use on the roof to work around the weather. As they completed sections of the roof, the tent was moved to new areas that needed to be worked on.
Fort Belvoir Military Base
Fort Belvoir Military Base, located in Northern Virginia, is now home to a Polyglass multi-ply modified bitumen roof system. NV Roofing proposed the Polyglass system to replace a 60,000 square foot aged TPO roof. The new roof system features mechanically attached Polyglass G2 Base sheet, heat-welded Polyflex® smooth interply sheet and heat-welded Polyflex® G granulated cap sheet in white. The redundancy of a multi-ply roof system results in a longer roof service life and return on investment for the building owner.
Joseph Caleb Daycare Center
Overview
Joseph Caleb Daycare, an early childhood education center in Miami, Fla., gets a new self-adhered, modified bitumen roof system. Roofing contractor Florida Building & Supply removed the existing failing roof and installed Polyglass’ roof system featuring CURE Technology® and ADESO® Technology. The daycare center, which caters to over 160 children, remained open during the roofing project.
Challenges
The project required an energy efficient roofing solution that also complied with the South Florida wind resistance requirements for high velocity hurricane zones. Furthermore, the building owner preferred a roofing solution that did not release fumes and odors during installation, narrowing the options available. Polyglass’ self-adhered modified bitumen roof system was a perfect fit for this project because of its high reflectivity, durability and ease of installation. In addition, waterproofing the existing skylights presented a challenge because they were irregular shaped. Polyglass’ PolyFlash 2C, an odor free, liquid flashing system was applied to the skylights to form full closure.
Roof System Components
The 20,000 sq. ft. roof features Polyglass’ three-ply, self-adhered modified bitumen roof system with a 20 year roof systems warranty. System components include:
- Elastoflex SA V, a self-adhered SBS modified bitumen membrane. This membrane was used for the base and interply sheets.
- Polyfreskco G SA, a white, self-adhered APP modified bitumen membrane was used for the surface layer of the roof system. Polyfresko G SA cap sheet is manufactured with CURE Technology, a thin-film technology that improves the membrane’s durability, UV and stain resistance, and granule adhesion.
- Polyflash 2C, an odor free, UV-stable fluid-applied flashing system was used to waterproof the skylights.
Sarasota High School, Fla.
Project Overview:
Founded in 1913, Sarasota High School in Sarasota, Florida has undergone several renovations to accommodate its expanding student body. As part of a $42 million campus redevelopment project, the Sarasota County School Board renovated several buildings on the campus. Springer-Peterson Roofing and Sheet Metal based in Lakeland, Florida was selected for the work. The roofing contractor recovered the buildings using Polyglass’ Polyfresko® G cap sheet. Polyfresko G is a highly reflective white APP granulated cap sheet membrane. It is manufactured with Polyglass’ patented CURE Technology®, a thin film technology that improves the membranes longevity. Membranes with CURE Technology are highly reflective, energy efficient, UV and stain resistant and retain granules longer.
Challenges:
The Springer-Peterson crew worked with a tight timeline to complete the 52,000 sq. ft. job. The roof was made up of 11 different roof areas with parapet walls a minimum of 4’ high separating them. Access was minimal on one side of the facility. The expansion joints were located at the walls making them challenging to install. The crew also had to protect the grass and sidewalks as they worked on the roof. The project was completed before school reopened in fall 2016.
The Roofing System Selected:
Springer-Peterson installed the Polyfresko G cap sheet to an existing substrate. The system was installed after perimeter fastening enhancements were in place to meet uplift requirements. Polyglass’ PolyFlash 2C liquid flashing system was used for the details. PolyFlash 2C is a fluid-applied urethane material using a fleece reinforcement which forms watertight flashings at joints, parapets, walls, and other penetrations.
Fort Worth Warehouse Facility
Project Overview:
In Spring 2016, commercial roofing contractor Empire Roofing installed Polyglass’ modified bitumen roof system on a warehouse building in Fort Worth, TX. The new 64,000 sq. ft. roof system was installed over an existing built-up roof (BUR). Empire Roofing, known for roofing expertise since opening its doors in 1942, selected Polyglass’ multi-ply modified bitumen roof system for the storage facility.
Challenges:
During the Polyglass roof system installation, a severe hailstorm hit Northern Texas slowing the roof work. More than 25 percent of the new roof was completed when the hail storm arrived. The golf ball-sized hail stones caused minor blemishes to the surface of the Polyglass Polyfresko® G cap sheet; however, the BUR portion of the roof had extensive damage. The damage to the BUR caused a delay in the project, but also provided a side-by-side comparison on roof performance during a severe hailstorm.
The Roofing System Selected:
Empire Roofing chose Polyglass’ high performing Polyfresko G cap sheet and Elastoflex SA V base ply. Polyfresko G is a highly reflective, white granulated modified bitumen membrane. It is manufactured with Polyglass’ patented CURE Technology®, a thin film technology that greatly improves granular retention. Membranes with CURE Technology are also highly reflective, and UV and stain resistant. The Elastoflex SA V membrane is a premium, self-adhered base ply roofing product, manufactured using patented ADESO® Dual-Compound Self-Adhered Technology, whereby a “true” Styrene-Butadiene-Styrene (SBS) modified asphalt compound is applied on the top layer and an aggressive self-adhesive compound is applied on the bottom layer.
