Roofing is a type of covering for a building’s top. It protects the building from the elements and helps it stay warm during winter and cool during summer. There are several types of roofs, including flat, pitched, vaulted, and domed. These types of roofs are determined by aesthetics, economy, and technical considerations. Read on to learn more about these roof forms. This article will discuss the various types of roofing materials, including their advantages and disadvantages.
Some materials and methods are more durable than others. For example, aluminum-pigmented asphalt is durable and UV-resistant. However, if exposed asphalt is used for roofing, it is susceptible to fading and degradation. Some roofing materials also require more frequent and more intense observation than others. To avoid mistakes, contractors should carefully examine each roof to determine its proper type. This increased observation will help them to identify inadvertent mistakes. Here are a few tips on selecting the right roofing system for your building.
First, check the building code. The International Building Code (IBC) has numerous provisions that address roofing systems. These codes provide guidance for the reroofing process. While some codes may require designers to submit construction documents to the building department, most inspectors don’t have the expertise needed to assess roof system performance. Hence, it’s best to work with a roofing professional who has experience in these projects. There’s no need to wait until an emergency arises for a roof failure to get inspected.
While choosing a roofing system, don’t let cost be the deciding factor. Cost is often an important factor. However, cheaper systems may not have all of the features you’ll need to protect your building. Additionally, they may not be as energy-efficient, making them less cost-effective over the long-term. If you need a new roof for a commercial building, make sure that you select a high-quality, well-known roofing company.
Before you select a roofing contractor, schedule a pre-roofing conference. This meeting should take place several weeks before roofing begins. Attend the conference with representatives from the general contractor, project manager, superintendent, and foreman. Other people who should be present should include representatives of the manufacturer of your roof covering material, mechanical contractors, electrical and lightning protection system contractors, and a third-party inspection firm. A pre-roofing conference is a great opportunity to address any issues you may have, so make sure to schedule a meeting.
In addition to installing new roof membranes, you should consider the type of roof vent you’ll use. A mechanically attached roof system may not be a good choice for a building that is in a high-wind zone. A reinforced membrane can prevent tear propagation in extreme weather conditions. However, the downside of a mechanically-attached roof membrane is that it places most of its mechanical stresses on the edges, which may lead to air pumping and condensation problems.
In addition to the benefits and disadvantages of different roofing systems, the service life of a roof system must be considered. For example, if a roof has a design life of 20 years, it will cost more than its replacement cost. However, a new roof that lasts for only 15 years will have a higher overall cost. Thus, it is important to select a proven roof system. A good roof is one that lasts for a long time.
