# Roofing Guides

These roofing guides answer the questions Los Angeles homeowners ask before they hire a roofer: what a new roof costs, whether the city needs a permit, which cool-roof rules a re-roof must meet, and when a repair is enough. Each one is written by AA California Roofing Staff, a licensed California roofing contractor (CSLB License #1147688).

## Start with the question you have now

The guides work best in the order a roofing decision happens. First decide whether the roof needs a repair or a replacement. If it is a replacement, look at what drives the price, then at the permit and energy-code rules the new roof has to pass.

## [Should You Repair or Replace Your Roof?](https://aacaliforniaroofing.com/repair-or-replace-roof/)

The signs that a repair will hold, the signs that the whole roof is done, and why the answer depends on the roofing material and on what an inspection finds under the surface. Read this first if you have a leak and do not know how big the problem is.

## [How Much Does a Roof Replacement Cost in Los Angeles?](https://aacaliforniaroofing.com/roof-replacement-cost-los-angeles/)

What sets the price of a new roof in Los Angeles: roof size and pitch, the material you choose, how many old layers come off, repairs to the deck found during tear-off, and the permit. It also shows how to compare two estimates line by line.

## [Do You Need a Roofing Permit in Los Angeles?](https://aacaliforniaroofing.com/roofing-permit-los-angeles/)

Which roof work needs a building permit in the City of Los Angeles, who pulls it, which inspections follow, and where to look if your home is in Pasadena, Santa Monica, Torrance or another city in the county.

## [Cool Roof Requirements in California: What an LA Re-Roof Needs](https://aacaliforniaroofing.com/cool-roof-requirements-los-angeles/)

What a cool roof is, how its reflectance is rated, and when California's Energy Code (Title 24) and the City of Los Angeles rules ask for one on a re-roof, for shingle, tile and flat roofs.

## [Tile vs Shingle Roof: Which Is Right for Your Los Angeles Home?](https://aacaliforniaroofing.com/tile-vs-shingle-roof/)

Which roof suits your house: how clay or concrete tile and asphalt shingle compare on cost, weight, slope, fire rating and cool-roof options, and what changes when you switch from one to the other on a Los Angeles re-roof.

## [Fire-Resistant Roofing in Los Angeles: Class A Roofs and Wildfire Zones](https://aacaliforniaroofing.com/fire-resistant-roofing-los-angeles/)

What makes a roof fire-resistant: what a Class A rating means, which roofing materials can reach it, and what a Los Angeles re-roof in a fire hazard zone has to meet.

## How we write these guides

- **Rules come from the source.** Permit and energy-code statements are checked against the agency that sets them, such as the City of Los Angeles Department of Building and Safety and the California Energy Commission, and each guide names its sources.
- **No made-up prices.** A roof's price depends on the roof itself, so the cost guide explains what moves the number instead of quoting averages. The real figure comes from a free on-site estimate.
- **Dated.** Every guide shows when it was published and when it was last updated, because codes and permit rules change.
