The International Building Code (IBC) has numerous provisions related to roof systems, including reroofing projects. These codes were originally developed for life-safety considerations, but have since been expanded to address a variety of other issues. The International Roofing Code also covers many other aspects of building envelopes, including drainage and airtightness. However, before deciding on a warranty, it is important to understand the coverage limitations and exclusions.
The eave or soffit is the lower edge of the roof. It prevents rainwater from rolling around the shingles, which can lead to leakage. This edge is made of asphalt-paper materials and is typically located at the junction of two roofs. For a more complete picture of the types of roofs available, refer to the following diagram. Typically, the eaves are located three feet from the top of the roof.
Asphalt-based materials, such as built-up hot-tar, are the most common low-slope roofing materials. They are typically installed by a professional, and they require specialized installation. Other types of roof materials are available, such as APP-MB sheets that are mechanically attached to the interply. However, it is important to note that asphalt-based roofing systems are susceptible to UV degradation and must be recoated periodically. They are also susceptible to wind blow-off, and it is advisable to consult a roofing specialist before settling on a particular type of roof material.
If your roof is in good condition, consider reroofing. This method is far less expensive than a full roof replacement. The old roof is not removed, so there is less time and labor involved. Moreover, you won’t have to remove all of the shingles. This saves a great deal of money and time. It is also more environmentally friendly. A new roof does not have to be completely torn off.
Reroofing, also known as overlaying, is another option. In this method, the new roof is applied over the existing one. However, this is only suitable for low-sloped roofs because it is not necessary to remove the old roof. This method requires only one installation, and it can only be done once. The new roof can only have two layers of shingles. This can be either a temporary or long-term solution depending on the severity of the problem.
Tiles and other materials are common roofing options. However, the material used for roofing may vary depending on the area. In areas with abundant rainfall, tile roofs are more appropriate for high-risk environments. Clay roofs, on the other hand, are often used in climates where rainfall is less than one inch per year. And while there are numerous benefits to these roofing methods, they are expensive to install. So, it’s important to consider the type of material you want for your home before deciding on the type of roof that will suit your needs.
Another option is to use rolled roofing material. This type of roofing is most common on utilitarian buildings and low-slope residential roofs. It is made of long rolls of asphalt or mineral-impregnated material. Each roll has a thickness of approximately three feet and covers about 100 square feet of roof space. Roll roofing is fast and convenient and can be applied using a torch-down technique or roofing nails. The benefits of rolled roofing are many.
