Where the water goes
A gutter is a short channel with a long job. Rain runs off the roof into the gutter, the gutter carries it to a downspout, and the downspout should release it away from the wall. When any step is undersized, clogged or sagging, water goes over the edge instead.
Common residential gutters are 5 inch K-style, with 6 inch for larger roofs, and downspouts are often 2 by 3 inches, roughly one for every 25 to 35 feet of gutter (Angi). Your installer sizes the system to your roof.
Rain season in East County
Brentwood's rainy period runs roughly from early October to mid-May, with February the wettest month at about 3 inches of rain on average (Weather Spark). Fall is when clogged or leaking gutters show up, so it is a good time to have them checked.
Rainy period: about Oct 5 to May 12 (Weather Spark).

Common questions
How much do new gutters cost?
Prices vary widely. National guides (Angi, HomeGuide) report anywhere from about $6 to $20 or more per linear foot for installed gutters, and roughly $1,200 to $9,000 or more for a whole house, depending on size, material and roof. No California-specific figure was published in them, so treat these as a rough range; a measured written quote sets your price.
Are seamless gutters worth it?
Seamless gutters are formed on site from one continuous piece, so a straight run has fewer seams that can leak. They usually cost more per foot than sectional gutters, and corners and downspout connections are still joined. Our seamless vs sectional guide lays out the trade-offs.
Do gutter guards stop all clogs?
No. Guards reduce how much debris gets in, but gutter guides we cite say they are not hands-off: leaves, pine needles and roof grit can collect on top and gutters still need periodic cleaning. Some types can also affect roof warranties if installed wrongly. See the gutter guard pros and cons guide.
Do I need a licensed contractor for gutters in California?
California's licensing board describes sheet metal work, including gutters, under the C-43 classification, and a written contract is required for home improvement jobs over $500. Check any installer's license at cslb.ca.gov before you sign.
