The Basics of Commercial Roofing Codes
Building codes are structural and performance requirements for any new construction, including roofing systems. State and federal agencies establish and enforce them to ensure public safety for anyone using them.
Roofing codes fall within this category and vary by location. It can be difficult to know–and keep up with–these ever-changing regulations.
The good news is that there are only a few key things to know about codes governing roofs for businesses that can ensure you are in compliance. Keep reading to find out more.
Roofing Code Basics
Most building codes come from some version of the International Code Council’s (ICC) model regulations. These can change over time; the organization updates them every three years.
ICC’s Chapter 15 lays out standards for the design and construction of rooftop structures. It specifies everything from height to the ability to withstand certain wind and precipitation. Note that residential structures have different roofing codes than commercial buildings.
Codes by Location
Most often, you will find that a governing body has adopted the original language of the model ICC code. Other times, they will amend it.
Some older buildings may have been built under a different code or no code at all. But state or local roofing codes for new construction may be more stringent than those laid out in Chapter 15.
For example, the ICC currently requires four nails to secure every asphalt shingle. Many states or cities that experience frequent high winds may mandate six nails.
Areas affected by hurricanes or tornadoes might have stricter standards for attaching sheathing. Or, places that get a lot of snow may have stronger load-bearing requirements relative to the pitch and roof material.
Relationship Between Energy and Roofing Codes
There is a separate set of energy codes that govern commercial buildings. These can have an impact on roofing construction though. For instance, the type of material used can impact the amount of insulation needed.
Since increasing the thickness of an insulating layer produces more thermal resistance, materials with higher R-values–or resistance to heat flow–require less insulation. Again, these codes will vary amount different climates.
Identify Prominent Businesses
It is important to ensure that you are operating under the most current set of roofing requirements. Most states and municipalities post them online, so they are easy to find.
If you are looking for commercial roofing here in the United States, one of the best (and easiest) things you can do is to find a prominent roofing company. You can be sure they will be knowledgeable of all roofing codes and requirements.
