The BP Canada website features an inspiration section that can help narrow down their choice. A free visualizer tool, also available on the company's website, will also allow them to virtually view different roofing options. "That's a great way for homeowners to try before they buy," Lambert concludes. Soprema's great advantage in the roofing category is that it has been in busi- ness for more than 100 years, and it applies its considerable expertise to develop a variety of high-end products that more than accommodate the challenges and expectations of complex building projects. One example is the expansion of Halifax's Ragged Lake Transit Centre, which aimed to accommodate 200 new electric buses to the city's transit fleet. This required major adaptation of existing infrastructure, and the Transit Centre roof became a key component of this process. Soprema was called upon to offer solutions focusing on rainwater management and energy optimization of the building, and after considering a host of options it decided to move away from the initial plans and propose a complete roofing system, from insulation and waterproofing to rainwater management and vegetated components (an approach that would also elimi- nate the risks associated with the use of products from different manufacturers). Specifically, for roof waterproofing, Soprema presented a conventional roofing system incorporating a mechanically attached Sentinel P150 PVC mem- brane, with two layers of Sopra-ISO insulation, as well as the support panel, mechanically attached for optimum stability. For water retention at the expanded facility, a hybrid-ballasted system was suggested combining a blue roof (Skywater) and a green roof (Sopranature) to maximize rainwater management performance. This solution would reduce the volume and flow rate of rainwater directed to sewer systems, as well as elimi- nate the need for controlled-flow drains. One of the key elements of the project was the integration of Sopraretentio Board, a drainage panel made of 100 percent recycled polyester that retains rainwater temporarily and then gradually releases the excess to help prevent excessive stagnation on the roof. By combining this with the Sopranature veg- etated system, the total volume of water retained was optimized and made available for capillary irrigation of the plants on the green roof. The entire installation was carried out by just one roofing company, and the Soprema team supported the contractor at every stage of the project, ensur- ing optimal application. Carlisle SynTec Systems has been a leader in the commercial single-ply roof- ing industry for more than 50 years and it provides customers with superior roofing systems via a select network of manufacturer's representatives, distribu- tors, and applicators. Carlisle's product offerings include Sure-Seal EPDM, Sure-Weld TPO, Sure-Flex PVC, and Fleeceback membranes. The company additionally provides metal roofing, coatings, sealants, vegetated roof components, skylights, pavers, and edge metal. One recent example of the innovative solutions Carlisle brings to projects involves Quanex, Inc., a global manufacturing company that needed roof replace- ments at their Rice Lake, Wisconsin facility. A severe hailstorm caused extensive damage to two sections of the 325,000-square-foot roof. Following the consult- ing process and studying the damage, 71,800 square feet of aged PVC membrane and 60,000 square feet of old adhered EPDM was replaced by a new product, Sure-Seal Cool Gray. Carlisle's Sure-Seal Cool Gray is a 1.52-millimetre non-reinforced EPDM- based elastomeric homogeneous roof covering, used for new single-ply roof construction and re-roofing applications. It offers superior hail damage resis- tance – EPDM-based solutions are considered superior to PVC membranes partly because it allows for thermal expansion – as well as added slip resistance of rub- ber and less glare than white roofs.
