It is essential that any reputable commercial roofing company have a solid understanding of roofing codes in its state. It is equally important for them to advise clients and prospects accordingly. We have made a list of some of the things you should consider before appointing a business to carry out work on the roof of your business.
Understanding California Commercial Roofing Codes
Types of Commercial Roofing Code
When your roof needs work, it seems straightforward to just call a contractor. There is a little more to it than that. Repairs, re-roofing, or coating, along with any roofing services need to be done according to the California roofing codes. Roofing codes are legal requirements that ensure your roof is fit for purpose and is safe. California laws cover a wide range of topics that all businesses and homeowners should look at before appointing a reputable contractor such as.
Check with any potential roofer that they have the correct 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 roofing project costing more than $500 must have a license with the Contractors State Licence Board. Reputable contractors will have this information on hand and available for anyone that requests it. In many cases, their license number will be listed on things like their website, social media pages, business cards, and letterheads.
A contractor also needs to have a permit before any work is carried out. Work on a commercial property must be covered by the California Building Code for all nonresidential properties. This covers 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. There’s a charge for a roofing permit but most of the contractors will make the necessary arrangements for this permit for customers willing to cover its fee. It is important to note that there are fines for anyone who goes ahead with roofing work without a permit.
This requirement is unique to California regulations. Cool roofs are made of materials that reflect the sun, so they retain less heat. They also reduce the need for air-conditioning, and reduce carbon emissions and lower energy bills. Your contractor should give you more information about cool roofs when asked. 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 Californian buildings, including commercial premises, are at risk of fire depending on their location in the state. California law states that all premises within an area that is at risk of fire must have a roof with a fire-retardant covering that is either Class A or Class B. This applies to 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.
California Commercial Roofing codes state that a new roof must have solar panels installed. This is part of an energy efficiency drive by the California Energy Commission that’s referred to as Title 24. In connection with this, there’s also a recommendation for businesses to use more LED lighting. More efficient air filters are also advised 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 popular because it’s cheaper than other roofing materials. It meets all the regulations needed and is 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 way of installing a waterproof surface on a new roof. Such a roof 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 and reduces energy bills. It also protects the building against the elements.
- Modified Bitumen: These are popular for businesses with flat or low slope roof areas. Modified bitumen is easy to apply, lasts a long time, is useful in fluctuating climates, and is compliant with California’s Commercial Roofing codes.
