What You Should Know About Residential Roofing Requirements

Getting your roof replaced can be a costly and stressful experience. You’ll want to make sure you’re working with a local roofing contractor who understands residential roofing requirements in California to avoid future troubles. The last thing you want is poor workmanship or failure due to not adhering to code.

Residential Roofing Requirements

The purpose of the California roofing policy is to establish a procedure that complies with the provisions of the California Residential Code (CRC) of 2016. The policy is intended to answer common questions that surround reroof permits in the county of Sacramento. It applies to one-and two-family dwellings and townhouses and not apartments or any commercial applications.

According to the roofing requirements, re-roofing permits must be obtained before starting any phase of the job, and its the responsibility of the roofing contractor and/or homeowner. Failure to obtain the necessary permits before the commencement of work will attract a violation fee equal to thrice the regular permit fee rate. However, repairs to a roof that does not surpass 10 percent of the total roof area, up to a maximum of 400 square-feet or whichever is less, will not require a permit.

Insulation Requirements

The quality of insulation is measured in terms of the material’s R-value (the measure of its resistance to heat flow). Sacramento County requires a roof system to have a minimum level of thermal resistance on residential buildings. For exterior walls, you need between R-13 to R-23, but for ceiling and attic spaces, you require R-30, R-38, and R-49.

Water Barrier/Underlayment

Underlayment is a thin layer between your roof sheathing and the finished roofing material. Typically, underlayment should be made of asphalt-saturated felt or other appropriate sheet material (including self-adhering) installed between a roof covering and roof deck. It is usually used in steep-slope roof constructions to help shed water and provide secondary weather protection for your roof. Both felt and self-adhering sheets must additionally provide fire and water resistance.

Roofing Material Quality Matters

The market is flooded with different new roofing materials, so you’ll need to study the qualities available to pick the right product. Whether it’s the traditional shingles or the emerging modern shingles, quality matters in the level of protection as well as longevity.

Asphalt shingles are the most popular roofing material in Sacramento and for good reason. Asphalt shingles are affordable, offer a wide variety of attractive options, and do a great job protecting homes from the elements of nature. Fiberglass shingles are especially desirable due to their lightweight and high resistance to tear. These shingles start with a fiberglass mesh mat covered in asphalt and topped with a layer of granules to provide color and UV reflection. 

Metal roofing has also enjoyed a recent resurgence triggered by demand for eco-friendly roofing, durability, and the introduction of new styles and colors. The manufacturing processes allow for a broad range of appearance options, including roofing materials made to look like shingles, tiles, or shakes. The most common metals used are lightweight steel, aluminum, and zinc.

OSHA Safety Measures

Roofing companies must provide their roofers with fall protection equipment that meets OSHA requirements every time they work six feet or more above the ground or the lower level. Fortunately, various fall protection systems on the market can provide roofers the flexibility they require during demolition and roof installation.

Certifications and Licenses Requirements

Roofing contractors in Sacramento, CA, must be licensed to work on roofing projects worth more than $500. Roofing contractors are categorized under the Class C Specialty Contractors License issued by the Contractors State License Board under the Department of Consumer Affairs. You must pass an exam to get a roofing license in California, but before you make an application, you’ll need to demonstrate at least four years of experience over the past ten years. The roofer must have worked as a journeyman level, supervisor, foreman, or contractor in the classification for which they’re applying for a license. Additionally, you’ll need a $15,000 surety bond for your roofing license.


The permit for roof replacement in Sacramento is the same permit you would require for any major construction work on your home. If you are doing any major renovation or just making a structural change, you will need a building permit.
