Traditionally, code requirements for roofing systems have focused on life safety concerns. However, today’s building codes include provisions for reroofing projects and general serviceability. To avoid issues with your roof warranty, you should check your contract with the manufacturer before relying on it. Listed below are some of the main concerns to consider when choosing a roofing warranty. Weigh the benefits and drawbacks of a roofing warranty before deciding on one.
The basic roofing system consists of rafters, which are cut from framing lumber. A more sophisticated roofing system can include pre-fabricated trusses, which are built in factories and then transported to the site and craneed into place. The rafters, which are usually made of plywood or OSB, are covered with shingles and secured with flashing. In addition, flashing is laid in strips below each shingle, with a sloped edge along the chimney.
The most common low-slope asphalt roofing material requires professional installation. Asphalt roll-roofing systems consist of layers of asphalt-soaked cloths. Newer versions of this type of roofing system are peel-and-stick and replace the more dangerous torch-down installed versions. Liquid-applied fiberglass or acrylic membranes can either contain imbedded fabric or not. Generally, these types of roofs are designed for maximum sun reflection.
Another common roofing problem is ice damming, which is a common cause of leaks along the eaves. This problem occurs when heat from the attic melts snow on the roof. The meltwater can then refreeze when it reaches the colder overhangs. Because ice dams prevent water from melting your roof, they may require a temporary fix or a long-term roofing repair. It’s important to note that reroofing is not the best option in every situation.
Some homeowners may opt to reroof their homes when their existing roof has seen better days. Although reroofing can be a costly process, it doesn’t involve tearing off the entire roof, which means that it’s less costly and takes less time. However, if your home doesn’t require a complete roof replacement, reroofing can be the best option. By reroofing, you can save money and reduce your stress level.
The disadvantage of mechanically attached roofing systems is that they are susceptible to wind blow off and future roof penetrations. Consequently, they can be risky for buildings in windy climates. This is because mechanical stress is concentrated on the edges. The roof may shift when wind gusts blow over it, resulting in a leak that hasn’t been repaired. This can lead to condensation problems as well. Using a roofing vent system isn’t the best idea because it can cause leaks and shift the insulation board.
The building department may require documentation that demonstrates compliance with building codes. Moreover, most building departments lack the expertise to assess the roof system’s compliance with the building code. Therefore, it is better to rely on a roofing professional who has more knowledge than a building inspector does. A good roofer is someone who has knowledge about the roof system and knows how to work within it. A well-qualified roofer will be able to ensure that all the necessary documentation is completed.
