Understanding Roofing Systems

A roofer’s job is extremely important because the roofing system influences the energy efficiency and practicality of your building. A roofing system is the covering on top of a building which includes structures and materials required to support it on top of poles, offering protection against rain, sunshine, extreme temperatures, and heavy wind. Furthermore, a roof is often a structural part of the entire building envelope. In fact, many buildings have roofs that are essentially a structural part of a whole building. It is therefore important to hire a qualified roofing contractor who can offer the best roofing solutions to your particular needs.

A roofing system basically consists of four components such as a sheath, tar, clap, and pitch. A sheath serves as the roofing membrane that covers the entire roof structure from the base of the pilings (the sheathing membrane) to the edges. Tar and clap are the two sheaths that are applied on the roof structure and serve as protective layers. In addition, pitch is the form of repetitive roofing system that is added to the sheath to allow for the attachment of more durable materials such as slate and glass to the roofing system.


While some roofing materials such as asphalt may be susceptible to weather and climate changes, others like slate, thatch, tiles, and wood shake are not. Therefore, your roof may need to be replaced every ten to twenty years depending on the climate in your area. This may be one of the main reasons why contractors recommend that their clients replace their roofs every few years to ensure the durability and long-term efficiency of your roof. By hiring a roofing contractor who has extensive experience with pitched roofing systems, you will be assured that your roof will remain strong for decades to come and will help reduce your home’s energy consumption. In addition, you will also be able to enjoy your roof for many years to come.
