Sociable Kitchen + Tavern in Ontario, Canada, is a modern destination celebrated for its unique design and lively ambiance. Catering to “beer nerds” and culinary enthusiasts, the venue required a roofing solution that would maintain a dry, welcoming interior while enhancing its aesthetic appeal and ensuring lasting performance. To meet these requirements, Nedlaw Roofs, a leading commercial roofing contractor in Ontario, was entrusted with the project. Their expertise, paired with the cutting-edge roofing solutions from Polyglass USA, resulted in an ideal partnership.

Known for handling large-scale roofing projects across Ontario and beyond, Nedlaw excels in roof replacement, new construction, and specialty roofing applications, including living roofs and green walls. Their commitment to project safety, efficient problem-solving, and using market-leading techniques has cemented their reputation in the industry.
Project Challenges and Polyglass Solutions
For the Sociable Kitchen + Tavern project, Nedlaw sought a roofing system that combined exceptional durability, superior thermal efficiency, and a rapid installation process, ensuring the project stayed on schedule without compromising the building’s sleek and modern aesthetic. The chosen system needed to not only withstand the challenges of Ontario’s variable climate but also integrate seamlessly with the overall architectural design, enhancing the visual appeal of the establishment.
Polyglass, a leader in the roofing industry, renowned for its state-of-the-art modified bitumen technology and self-adhered membranes, emerged as the ideal partner. Their advanced roofing products, designed for performance and efficiency, provided a comprehensive solution that met the project’s demanding specifications while upholding the high standards of both functionality and design excellence.
The roofing installation was a technically complex endeavor, requiring meticulous planning and execution across multiple stages. The critical steps, utilizing Polyglass products, were as follows:
1. Vapor Barrier Installation:
- Material: PolyVap SA G
- Installation: Install kraft paper vapor barrier and ensure all laps and penetrations are properly sealed to prevent moisture ingress.
2. Insulation Layer:
- Material: 1.5″ ISO-Polytherm 4×8 (Polyisocyanurate Insulation)
- Installation: Mechanically fasten one layer of 1.5″ ISO insulation to provide thermal resistance and structural support.
3. Base Sheet:
- Material: Elastoflex SA Base (Self-Adhered Modified Bitumen Base Sheet)
- Installation: Apply one-ply of the self-adhered modified bitumen base sheet, using primer as needed for optimal adhesion. This layer serves as the foundational waterproofing layer.
4. Cap Sheet:
- Material: Elastoflex SA P Black Cap (Self-Adhered Modified Bitumen Cap Sheet)
- Installation: Apply one-ply of the self-adhered modified bitumen cap sheet over the base sheet for enhanced weather resistance and a clean finish.
5. Tie-In to Existing Membranes:
- Material: PolyPlus50 Modified Flashing Cement
- Installation: Use PolyPlus50 Modified Flashing Cement around the perimeter as part of Elastoflex SA P flashing detail.
6. Flashing at Parapets and Perimeters:
- Material: Two-ply Modified Bitumen Membrane Flashings using Polytack High-Tack Contact Adhesive and PolyPlus 50 Modified Flashing Cement
- Installation: Install a two-ply modified bitumen membrane system at parapets and all perimeter locations using Polytack Hi-Contact Adhesive to adhere Elastoflex SA Base and PolyPlus 50 for the Elastoflex SA P to reinforce the vulnerable areas against water infiltration.
7. Fasteners and Plates:
- Material: Standard Fasteners and Plates
- Installation: Use approved fasteners and plates to mechanically secure insulation and roofing components as needed throughout the assembly process.
Efficiency and Outcome
Drew Walden of Nedlaw emphasized the notable advantages of Polyglass products, particularly their efficiency and ease of installation. The self-adhering design of the Polyglass membranes significantly streamlined the application process, reducing installation time and ensuring the project remained on schedule despite its technical challenges. This innovative feature proved instrumental in delivering a seamless and timely roofing solution.
The completed roof successfully addressed the building’s functional requirements while perfectly complementing the sleek and modern aesthetic of the Sociable Kitchen + Tavern. The result was a durable, watertight roofing system that not only provided long-term protection and reliability but also enhanced the venue’s architectural design. Both the client and contractor expressed their satisfaction with the outcome, recognizing it as an ideal blend of practicality, performance, and visual appeal.

Product Spotlight
Elastoflex SA Base
Elastoflex SA Base is a premium self-adhered elastomeric base membrane manufactured using patented ADESO® dual-compound, self-adhesive technology, where 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. Features a high-performance reinforced polyester mat to enhance puncture resistance and dimensional stability.
Elastoflex SA P
A self-adhered Styrene-Butadiene-Styrene (SBS) granulated cap sheet for use in low-slope roofing. Elastoflex SA P is manufactured using Polyglass’ patented ADESO® dual-compound, self-adhered technology. With this technology, a “true” elastomeric modified asphalt compound is applied to the top of the membrane and a proprietary self-adhesive SBS compound is applied to the bottom. Constructed with a tough non-woven polyester reinforcement that provides flexibility and dimensional stability, as well as excellent tear and puncture resistance.
PolyBrite Reinforcing Polyester
PolyBrite Reinforcing Polyester is a stitchbond, light-weight, high-performance polyester fabric designed to reinforce seam mastics on metal roofing projects. The flexible nature of this fabric allows ease of application over the critical corrugations and laps found in metal roofing.
Polytack
Polytack is a low Volatile Organic Compounds (VOC) quick-drying, solvent-based, high-tack contact adhesive formulated to promote maximum adhesion of self-adhered membranes for applications where adhesion is more challenging.
Polytherm
Polytherm is a highly energy efficient rigid insulation board composed of a closed-cell Polyisocyanurate foam core laminated to a fiber reinforced black non-asphaltic organic facer for superior bonding characteristics. Manufactured with a facer ideally suitable for many types of roofing products, including the direct application of ADESO® dual-compound self-adhered membranes under most project circumstances.
PolyPlus 50
PolyPlus 50, a premium modified wet/dry cement, is a superior quality formulation for use in a wide variety of roofing applications such as Styrene-Butadiene-Styrene (SBS) roofing systems, various other membrane systems, and in wet, damp or underwater conditions. Can also be used for emergency repair of shingles, Built Up Roofing (BUR), concrete and general damp proofing. Its heavy “trowel-grade” consistency makes it ideal for flashing details, attachment of membrane to steep slopes and parapet walls, and a variety of waterproofing repairs.
