A flat roof differs from a traditional sloped roof in that it is basically horizontal, although not exactly. Flat roofing utilizes a minimal inclined angle that is designed to allow water and other debris to freely move off of the roof. Originally, flat roofs were predominantly found in warm weather locations with little precipitation and they used a tar and gravel approach to cover the flat roof area. This method was not ideal in colder climates, as it would often lead to snow and ice dams blocking the flow of water. Additionally, these materials are heavier in weight, which commonly caused the roof to sag and threatened the structural soundness of the building.
Flat roofing technology has come a long way in the last 20 years. Currently, specially designed roofing materials and membranes are used in flat roofing systems. The main purpose of the membrane is to waterproof the designated area. These membranes are applied on top of the roof as a continuous sheet, as much as possible, with the help of sealants and adhesives. These roofing products are great in that they allow the bonding of multiple sheets and reinforcing parts where it's penetrating the roof surface.
Thermoplastic Polyolefin, or TPO’s as they’re more commonly referred to, changed the landscape for flat roofing. TPO membranes were first used as a roofing material in the early 1990’s and they allowed for flat roofs to be a more viable option in harsher climates. TPO flat roofing systems are made up of ethylene propylene rubber; and combine the durability of rubber with the proven performance of hot-air weld-able seams. The result creates a very high performance type of product. TPO roofs are beneficial by providing the following:
• Exceptional resistance to ultra-violet rays
• Ozone and chemical exposure
• Extremely heat reflective
• Energy efficient
• Environmentally friendly (as it's a recyclable product)
• Durable from tears and punctures
• Fire resistant
