Flat roofs, also known as low slope roofing systems, are not entirely flat. They may look horizontal or nearly horizontal, but they usually have a slight slope of about 10 degrees to allow water to drain off.
Flat roofs have been around for centuries and the old technology of using asphalt compounds to deflect water was being used until thirty years ago. New technologies minimize the use of asphalt where possible and also provide insulation properties, as well as waterproofing.
Benefits of flat roofs are that they are more accessible making it easier to inspect, maintain and clean. With a properly maintained flat roof, you can extend the longevity of your entire roofing system.
Flat roofs can potentially increase the insulation value of your home. Foam roofing systems, for example, have an inherent insulating value that can reduce your cooling costs and help the environment by reducing the heat reflected off your roof.
Proper drainage, usually in the form of scuppers, are essential for proper maintenance of your flat roof. Without proper drainage, your flat roof can pond water and debris, which accelerate the breakdown of your roofing materials. This can void your manufacturer’s warranty and significantly reduce the life of your roofing system.

Components of Pitches Roofing Systems
Additional Roof Protection
In addition to your roof covering, a protective waterproof coating will protect your roof investment and provide a longer life to your flat roofing system. Coatings come in many varieties, colors, and applications ranging from 5-10 years of protection. Coatings are a standard component of your flat foam roof systems, but can also be used in a number of roofing systems, such as modified. Coatings must be reapplied, and maintained properly to protect the roofing materials on your home. Check with your Lyons Roofing Representative for information on your specific roofing system.
Your roof deck provides the foundation for your roofing materials. The decking is sheets of wood (generally OSB or plywood) that are secured to the rafters of your home.
In some cases the decking may need to be replaced if its integrity has been compromised, usually due to age and normal wear and tear. There are many reasons this can occur including; inadequate attachment of existing panels, sagging or ridging between supports, soft and wet panels, mold/mildew growth at panels, or delamination. You may be able to identify bad decking by simply walking on it or by looking at the underneath of your decking (if you can see it from your attic). Very often however, you cannot determine the condition of your decking until your existing roof covering is removed. Your Lyons Roofing superintendent will advise you during the re-roofing process the condition of your decking and what options are available.
