EPDM (Ethylene Propylene Diene Monomer) is a form of rubber specially designed to be formed in to large membrane sheets which makes this the choice roofing system for large open areas.
EPDM roofing system options include:
Loose Laid and Ballasted
The roofing system components such as the vapour barrier, insulation and EPDM membrane are simply laid on the roof and kept there by gravity in applying a top layer of gravel ballast. The gravel ballast also serves as a protective layer for the roofing membrane. The loose laid ballasted EPDM application is the most cost-effective system in the market and can be applied in almost any temperature or climate. This is the perfect roofing system for large warehouses and commercial retail units. This is also the most cost-effective life cycle roofing system available, as roof replacement costs are typically lower than other roofing systems.
The roofing insulation is fastened to the substrate (roof deck) using specialty fasteners and plates.The membrane can then be fastened through the system components down to the substrate at the seams. This type of application requires a variation of the EPDM membrane that is reinforced with polyester. The mechanically fastened option is more suited for smaller roof areas with multiple elevation changes.
The roofing system components are glued to the substrate with specialty adhesives.This option is less cost-effective than the other two, and has cold temperature restrictions but offers benefits in being a light weight roof system with superior uplift properties.
TPO / PVC Single Plys:
TPO (thermoplastic polyoleﬁn) and PVC (polyvinyl chloride) are both Thermoplastic roofing membranes. What that means is that the membrane can be heat welded to itself to create 1 large sheet membrane out of multiple sheets.TPO and PVC membrane are typically white in colour. This is an important attribute when considering the environmental impact of a building. As white is the most reflective colour, your roof will reflect heat and UV rays.This can help reduce what is called the “Heat Island Effect”, which is common is most cities. Because of the construction materials used in cities, the average temperature in a city will be higher than in the country. It can also help reduce air conditioning costs.
TPO roofing system options include:
The roofing insulation is fastened to the substrate (roof deck) using specialty fasteners and plates. The membrane can then be fastened through the system components down to the substrate. The mechanically fastened option is the most cost-effective application method for TPO and PVC systems. It also has very few temperature / climate restrictions.

SBS Modified Bitumen:
SBS (Styrene Butadiene Styrene) is an elastomeric additive to asphalt that when cooled exhibits rubber like properties. Asphalt roofing is the oldest form of low-slope “Flat” roofing still in use today. Traditionally, asphalt roofing systems were creating by embedding felt paper in multiple layers of hot asphalt essentially creating a membrane on the roof. SBS roofing systems are the next evolution in the asphalt system. SBS membranes take the waterproofing properties of asphalt roofing and add countless benefits by factory forming a roofing membrane with superior waterproofing, UV resistance and long-term durability properties. SBS roofing membrane systems are classified as 2-ply or multi-ply as they require a minimum of 2 layers of membrane bonded to each other to create the most effective waterproofing solution. The top layer has small rock granules embedded in the membrane to provide UV protection. These granules are available in a variety of colour including white for the environmental solutions.
SBS modified bitumen roofing systems have evolved to include a wide variety of products and application methods depending on the client’s needs and wants.
Some of the more common application methods are:
The roofing system components are adhered to the substrate with specialty adhesives or hot asphalt. The top ply “Cap” membrane is typically heat welded to the bottom ply “Base” membrane by propane torch.

It also has very few temperature / climate restrictions. The top ply “Cap” membrane is typically heat welded to the bottom ply “Base” membrane by propane torch.
-SBS membrane are also very durably and are the most recommended solutions for high traffic roof area’s or for underneath paving stones on roof top patios.
-SBS membranes can also be used for foundation waterproofing.
Built-up-roofing is a commonly used term for flat roofing in general because of the way it’s put together in layers from the roof deck up.
Built-up-roofing, lately, is the industry term used for multi-ply felt and asphalt roofing. Felt and asphalt roofing is the oldest method of flat roofing still used in the market today.
Built-up roofing is simply embedding roofing components such as insulation and felt sheets in layers of hot asphalt.
The top surface is then covered in pea gravel to protect the membrane from UV exposure.
It has been proven effective over time however with the advances in roofing technologies is slowly being phased out.
CCS Contracting Ltd. works with General Contractors, roofing agencies, and building owners to provide the highest quality roofing solutions for new buildings in the Alberta marketplace.
We have a highly qualified, highly experienced team that will give the highest level of service from start to finish of every project.

We will continue that same high degree of service through the construction phase of all projects to ensure that every project receives a high-grade roof system constructed to the highest standards in the industry, within our clients schedule and budget.
We are ARCA (Alberta Roofing Contractors Association) members and are approved installers for all roofing systems available.
CCS Contracting Ltd. offers full roof replacement services. As nothing lasts forever, sometimes the best option to extend the life of a building is to replace the roof system.
We work closely with our building owners, property managers, inspection agencies and contractors to provide the best solution to bring maximum benefit to our customers.
The team at CCS Contracting can offer services right from the inspection phase of your roof. We have highly trained and highly qualified personnel that can inspect all roof systems, and provide reports and options for solutions to problematic older roofs.
From the inspection and reporting services we will offer pricing packages and options based on our customer’s needs, and offer professional recommendations, on which options will have the most benefit to the customer.
Metal roofing is another option that CCS Contracting can provide to our customers.
We roll our own Job-Site Manufactured (JSM) metal roof panel available in a wide variety of colour choices.
Metal roofing is a viable option for pitched roofs. They can be straight forward and simple for large industrial style buildings, or spruced up for highly architectural buildings.
Metal roofing is very durable and is made from factory painted sheet metal that has paint finishes that will hold up for years.
CCS Contracting will custom form trims and flashings to match and suit any of our metal roofing projects.
