While the requirements for roofing systems have undergone some changes over the years, one of the main concerns remains the need for a reliable and durable roof. While code requirements for roofs were originally designed to address life-safety concerns, the International Building Code now has several provisions for roofing systems, including general serviceability. In addition to the requirements for a safe roof, the International Building Code also includes provisions for reroofing projects. To avoid mistakes and improve the quality of the roof, the contractors involved in roofing projects should observe the requirements for a specific roofing system, including its installation and composition.
Gable and mansard roofs are easy to measure, while complex gambrel and shingle roofs require more intricate work. When measuring an intricate roof, waste becomes an important issue because shingles need to be cut to fit in narrow spaces or nailed in even rows along the roof deck. Not every square foot is equal, so the phrase “roof square” is helpful for both simple and complex roofing projects.

Before beginning your roofing project, it is a good idea to hold a pre-roofing conference. This meeting should take place several weeks prior to the start of the roofing project. Attendees should include the general contractor, the project manager, superintendent, foreman, and any representative of the manufacturer of the roofing materials. Other stakeholders should be invited to the meeting, including mechanical, electrical, and lightning protection system contractors. The third party inspection firm should also attend the pre-roofing conference.
A mechanically attached system may not be suitable for buildings in high wind zones. Reinforced membranes may also prevent tear propagation. Nevertheless, the material is brittle, and PVC membranes made in early versions often suffered catastrophic failures. To ensure a long-term performance of your roofing project, choose a high-quality membrane that has a good track record. This roofing method will last for several decades. The advantages are many.
A roof designer must consider several factors before selecting a roofing system. First, cost is often a determining factor. Lower-cost roofing systems may not provide all the features required by code. They may also be less energy-efficient and require more maintenance. As a result, they may end up costing you more money over time. So it is important to take all these factors into account before making a final decision. But if your budget is limited, the Guide will help you make an informed choice.
XPS: Unlike polyisocyanurate insulation, XPS does not absorb water, making it an excellent roofing solution. However, it needs a cover board to enhance its durability. XPS boards can be installed on plaza decks for their high compressive resistance. These boards can withstand high pedestrian loads. Additionally, XPS boards with high compressive strength are available for plaza decks and other areas with heavy vehicular traffic.
