Building codes, the rules of roofing.
There are rules established by the federal, state, county and city governments on how to install a roof properly so it is built to code. The installation instructions provided by the roofing manufacturer should meet most requirements and many practices are the same across the country. Keep in mind you should still check as certain areas have different rules or building codes. For example, Florida has special requirements for wind uplift, while California has Title-24 Cool Roof laws.
It’s important to double check when you do or do not need a permit. Some areas require permits for an entire roof or addition but not for minor repairs, however, it depends on where you live and the work being done. While some people may choose not to pull a permit, there can be major consequences if you’re caught, such as paying a fine or having to remove the roof so the city can inspect what’s underneath.
