Our Ranking Methodology

Our process involves collecting a list of about 24,000 companies nationwide and analyzing their online presence. We extract their highlights and lowlights using machine learning and natural language processing. Using this information, we score each company based on a combination of review criteria, including:

• Experience: The company should have evidence of experience in its industry, and should employ quality contractors.
• Service area: Whether or not the company services your city, as well as how many areas in the city it services. Companies with a larger service area score higher.
• Customer experience: We take a look at each company's customer reviews to determine how satisfied customers are with the company's service and products.
• Accreditation: Companies with proper licensing and knowledgeable professionals rank higher.
• Pros and cons: We sort the above factors into pros and cons for the company, such as roofing materials available, customer satisfaction and reviews, and cost, and weigh the score based on those.

Then, we map companies based on service area and show the most relevant providers in your area based on each company's distance from you and its overall scores.

Roof Replacement

Replacing a home's entire roof is a common service in San Francisco and the surrounding area. A roof replacement costs around $5,000 to $15,000 on average. However, your actual cost will vary depending on several factors such as your roofing material and home square footage. The roofing material will be a big percentage of the overall cost. For example, asphalt shingles cost between $1 and $3 per square foot, so if you have a 2,200-square-foot home, just the materials will cost between $1,200 and $6,600.

Roof Repair

Roof repair is an essential service in many places. The cost of a roof repair varies because it depends on how much damage needs to be repaired, but it can cost you as little as $150 and as much as $15,000.

Roof Cleaning

Roof cleaning is another kind of roof work San Francisco residents need. The main reason for roof cleaning in San Francisco is moss growth. A roof cleaning costs between $300 and $700 for most homeowners.

Which materials are best for San Francisco's climate?

The weather can put enormous strain on your home's air conditioning and heater if you don't have the right roofing style. To help you decide, here are some pros and cons for a few different roofing materials:

• Energy efficiency: Metal is the most reflective and, as such, offers the best energy-efficiency in San Francisco. Clay roofs are dense and can provide outstanding efficiency as well.
• Solar installation: If you plan on installing a solar system on your San Francisco home, you might want to consider the lifespan of the roofing material you're installing. Solar panels last an average of 20 to 30 years, while asphalt lasts 15 to 20, so you may want to opt for a material that lasts longer than solar panels, like slate, clay, or metal.
• Resistance to moss growth: Moisture is something you should consider as well, particularly for moss growth. Moss is most devastating to asphalt roofs, but it can also cause damage to clay and other materials, like slate shingles. Metal is an option that isn't affected by moss growth as much.

Signs I should replace my roof

Figuring out when to replace your roof in San Francisco can help avoid potentially devastating roof issues, including roof leaks. There are some factors that should cause you to call for roof replacement.

First, if you experience a single roof leak, you might be able to get by with a simple repair, which will cost much less than replacing your entire roof. However, if you notice multiple leaks or consistent issues with leaking despite repairs, your roof most likely needs replacement.

If you're installing solar panels on your home soon, you might want to consider roof replacement before the panels are mounted on your roof. A new roof underneath your solar system will help lower the risk of necessary roof maintenance after installation.

Finding the right roofing company

Finding the right roofer in San Francisco means searching for a company that offers the services you need, has good customer service, has pricing that fits into your budget and offers a good warranty.

First, we suggest considering how many years of experience the company has. Choosing a roofer with a long reputation helps you avoid poor customer service, growing pains and other issues that are more common with newer companies.

Also, you should always check that your roofing or construction company holds the proper license to do roofing work in San Francisco. Also, roof installation and replacement need building permits in San Francisco. You should talk about permits with your contractor prior to signing a contract.

Pricing will always be an important factor, and you might be able to narrow your list down to exclude companies that are outside of your budget. Just make sure to compare companies based on the value provided as well as the overall price.
