The 10 Best Gutter Installations in San Francisco (2026)

This ranking is based on Google review data and uses a Bayesian weighting that balances each business’s average rating with its number of reviews. That approach favors consistently high ratings while accounting for review volume; the list was updated in 2026 to reflect current scores and counts.

Verify that the contractor has proper insurance and any required local licenses, ask for a written estimate, and request references or recent photos of similar work. Also confirm who handles permits or building-code compliance if your project affects rooflines or involves structural changes.

Schedule gutter work before the rainy season or after a string of storms and heavy leaf fall to prevent clogs and water damage. If you notice overflowing gutters, visible sagging, or water pooling near foundations, arrange an inspection sooner rather than later.

Compare multiple written bids that break down labor, materials, gutter profile, and warranty terms. Consider the lifespan and maintenance needs of different materials, access and roof complexity, and whether the estimate includes downspouts, fasteners, and debris guards.
