Why Gutter Installation Matters for Your San Francisco Home
San Francisco averages 24 inches of rain annually, with heavy storms dumping 1.5 inches in a single day. Without properly sized gutters, water pools against your foundation, seeps into your basement, and rots your fascia boards. We've replaced hundreds of undersized 4-inch gutters with 5-inch or 6-inch systems that move water twice as fast.
Our Gutter Installation Process: Step by Step
- Inspection and Measurement – We climb onto your roof and measure every roofline, noting valleys, dormers, and downspout locations. We calculate the drainage area in square feet, then apply the San Francisco Building Code formula: one square inch of downspout cross-section per 100 square feet of roof.
- Material Selection – You choose from three options: 26-gauge galvanized steel ($8–$12 per linear foot), 0.032-inch aluminum ($6–$9 per linear foot), or 16-ounce copper ($18–$25 per linear foot). Copper develops a green patina over 5–7 years and lasts 50+ years. Aluminum comes in 20 colors, including San Francisco Fog Gray and Bay Bridge Bronze.
- Seamless Fabrication – We bring a mobile gutter machine to your property and extrude continuous lengths up to 50 feet, eliminating joints that leak. Each section is cut to within 1/16 inch of your roofline.
- Installation – We fasten gutters with hidden hangers every 24 inches—closer than the standard 36 inches—to prevent sagging under wet leaves. Downspouts are placed at every 40-foot run, with splash blocks directing water 4 feet from your foundation.
- Testing – We run a garden hose at full pressure through each gutter section and inspect every joint. No leaks? We clean up all debris and show you how to maintain your system.
Cost Ranges for Gutter Installation in San Francisco
A typical single-family home (1,500–2,000 square feet of roof) costs $1,200–$2,800 for aluminum gutters, $1,800–$3,800 for steel, and $4,500–$8,000 for copper. These prices include downspouts, hangers, splash blocks, and removal of your old gutters. We charge $50–$75 per hour for gutter guard installation, adding $400–$1,200 total.
How Long Does Installation Take?
Most residential jobs take 1–2 days. A straightforward ranch-style home with 150 linear feet of gutter is finished in one day. A complex Victorian with multiple rooflines and 300 linear feet takes two days. We schedule within 2 weeks of your signed estimate.
Gutter Guards: Should You Add Them?
San Francisco's eucalyptus and pine trees drop needles that clog gutters within weeks. We install three guard types: micro-mesh stainless steel ($12–$18 per linear foot), foam inserts ($4–$7 per linear foot), and surface-tension helmets ($10–$15 per linear foot). Micro-mesh blocks 99% of debris while allowing 40 gallons per minute of water flow. We recommend micro-mesh for homes with overhanging trees.
Warranty and Longevity
All our gutter installations carry a 10-year workmanship warranty—no leaks, no separation, no sags. Aluminum gutters last 20–30 years, steel lasts 15–25 years, and copper lasts 50+ years. We register your warranty with the manufacturer and provide a digital copy.
