May 15, 2023Blog, Costs, Roof Replacement, San Francisco

The roof of your home is key to keeping you, your family, and your possessions safe from the weather conditions and nature. We usually don’t think about the integrity of our roof until there are complications. A variety of circumstances can arise which will force us to review the status of our roofing system. Perhaps storm damage, age, or leaks are present which need some addressing.

The average cost of a new asphalt shingle roof in San Francisco is between $5,000 and $21,000. This cost depends on a variety of factors such as the size of the home, the roofing materials you choose, and the installation costs of the San Francisco roofing contractor. On average, asphalt shingles will cost between $500 and $700 per square.

Roofs are measured in “squares”. A 100-square-foot area is considered 1 square in roofing terms. To simplify, the amount of material needed to cover 100 square feet of roof area is equal to 1 square of roofing material. So, as an example, if a roof surface area is 2000 square feet, the contractor would figure 20 squares. You can approximate how many squares your home is by dividing the square feet of your roof area by 100.

Here is a rough estimate of the breakdown:

  • 10 square roof: $5,000 to $7,000
  • 15 square roof: $7,500 to $10,500
  • 20 square roof: $10,000 to $14,000
  • 25 square roof: $12,500 to $17,500
  • 30 square roof: $15,000 to $21,000

The following factors will help you determine if a full roof replacement is the best option for your home. Of course, it is wise to have a professional inspection done to validate your findings.

Water Leaks

Brown or yellow stains on your interior ceilings are an indication that your roof is no longer holding up as it should. A small, single leak can be easily repaired, however, if the roof has multiple areas of weakness, a complete replacement is recommended.

Missing or damaged shingles

Have you noticed any missing or damaged shingles? It is best to have the areas inspected, especially after a storm, and replace the damaged or bent shingles. Unfortunately, there are times when the damage is larger than expected, and a full roof replacement is the best option.

Age of Your Roof

The duration of roofing materials differs. Asphalt shingles last approximately 20 years, while a metal roofing system can last 40 to 70 years. It is wise to learn how much life is left in your roof and keep a close eye on whether it is best to upgrade your roofing system so you don’t have to worry about replacing it later in life.

What are some considerations when it comes to installing a new roof?
