What You Should Know About California Commercial Roofing Codes
Types of Commercial Roofing Code
There is a wide range of topics within California laws that all businesses and homeowners should look at before appointing a reputable contractor to perform work.
- Roofer License: Check with any potential roofer for a correct and current license. You should ask to see the roofer’s license and ask for their license number. California state requires that any contractor working on a project that costs more than $500, must have a license with the
- Contractors State Licence Board: The reputable contractors out there will provide this information happily and often already have it on display for their customers. Many have their license number listed on things like their website, social media pages, business cards, and letterheads.
- Roofing Permit: All roofing contractors must have a permit before any work can be done. Work on a commercial property must be covered by the California Building Code for all nonresidential properties. Topics such as materials used, how they’re installed, moisture content of fire retardant treated materials, roof framing and impact resistance, seismic anchorage, and radiant barriers are all covered. Roofing permits do have a fee but contractors will make the necessary arrangements for this permit for customers who are willing to cover the cost. It is important to note that there are fines for anyone who goes ahead with roofing work without a permit. Many contractors will take care of the permit arrangements for you.
- Cool Roofing Systems: This requirement is unique to California regulations. Cool roofing systems are made of materials that reflect the sun, which means less heat is retained. They also reduce carbon emissions, reduce the need for air conditioning, and lower energy bills. Ask your roofer about cool roofing and they should provide you with all the information you need. Commercial properties need to have a cool roof if they are replacing half of their roof or at least 2,000 square feet of it, whichever is the smaller amount. A cool roof also has to be rated by the Cool Roof Rating Council, which evaluates the solar reflectance and thermal emittance of roofing products.
- Fire Safety and Commercial Roofing: Some commercial Californian buildings are at risk of fire depending on their location. Premises within a risk area are required by California law to have a roof with a fire-retardant covering that is either Class A or Class B. This applies to both new and repaired roofing. Class A is for areas with a high risk of fire, and Class B is for areas that are lower risk.
- Solar Roofing: All new roofing is required to have solar panels per California Commercial Roofing codes. This is part of Title 24, an energy efficiency drive by the California Energy Commission. There are also recommendations for businesses to use more LED lighting to conserve energy and more efficient air filters to prevent hazardous substances from getting into buildings.
There are several options for commercial properties to choose from when it comes to roofing:
- Asphalt Shingle: This is the cheaper option and it meets all the regulations needed. It is also quick and easy to install. You can choose from several types of asphalt shingles including fiberglass which lasts the longest. Shingle roofing typically lasts about 20 years whereas a metal roof will go for close to 50.
- Cap Sheet: This is a great waterproof surface for a new roof. The cap sheet is fixed by using tar-coat or asphalt over layers of fiberglass. Installation is done over several layers and then coated with mineral granules. Cap sheet roofing creates a sturdy and robust roof that reflects heat, reduces energy bills, and protects the roofing against the elements.
- Modified Bitumen: These are popular for buildings with flat or low slope roof areas. Modified bitumen is easy to apply, long-lasting is useful in fluctuating climates, and is compliant with California’s Commercial Roofing codes.
