COMMERCIAL ROOFING SYSTEMS
Selecting the best commercial roofing system for your building or project is one of the most critical decisions any property owner or design professional will make.
Remember that your roofing system is protecting a very large investment and is usually your first line of defence. Poor choices in your roofing system could eventually result in expensive roof repairs, premature replacement and/or extensive damage to the building and its contents. Whether you are constructing a new building or considering the replacement of roof that is nearing the end of its useful life – there are primarily six major classes of roofing systems available: 1) EPDM ROOFING EDPM is one of the simpler roofing systems to install and maintain compared to other commercial roofing products. Its versatility and durability give it one of the longest lifespans available. 2) THERMOPLASTIC ROOFING (TPO) TPO is quickly becoming one the commercial roofing systems of choice. With its low temperature flexibility, high temperature tolerance and extreme durability – these roofs are especially resistant to chemical exposure and ultraviolet light. TPO roofs are resistant to high winds, punctures, chemical damage and can be expected to last upwards of 20 years or more. 3) BUILT UP ROOFING (BUR) Built-up roofs are composed of alternating layers of reinforced fabrics and tar or asphalt. A BUR roof is built on site and may use a number of different materials. Layers of roofing felts can be reinforced with glass or organic fibre mats. Asphalt or a cold adhesive product is used between each layer. The last ply layer is usually topped with a coat of asphalt and covered with imbedded aggregate. Sometimes the BUR system will completed with an elastometric coating, aluminum coating or a mineral surfaced cap sheet. 4) MODIFIED BITUMINOUS Modified Bituminous is similar to BUR membranes and is composed of various levels that are adhered with peel and stick adhesive or hot asphalt. The surface layer usually has a coating of rock aggregate, metal foils, mineral granules and liquid coatings. |

5) PHOTOVOLTAIC SOLAR PANELS
As Alberta moves towards sustainable and green energy, many commercial building owners are considering solar roofing systems as way to reduce costs and cut down on greenhouse gas emissions. Photovoltaic solar panels absorb sunlight which is converted to energy to power and heat commercial buildings. Alberta’s introduction of carbon taxes in 2017 may start to place upward pressure on energy prices and begin to make photovoltaic solar power an even more attractive option.
6) GREEN ROOFING
There are two basic classes of green roofs – intensive and extensive. Each type of system has a number of factors that need to be considered before any construction decision. Green Roof technology can only be use on a roofing system that has the structural strength to support the added weight.
Extensive Roofing Systems
Extensive Roof systems are used in a renovation or retrofit project. A blanket of soil and plants is placed on an existing roof with a waterproof barrier. With only 50 - 150mm of soil and material – their lightweight design is are not intended for public access.
Intensive Roofing Systems
An Intensive Roofing System is more complex and used on new construction projects where the building’s design has the structural capacity to accommodate a wider range of trees, shrubs, irrigation and the added weight of public access.
