Gutter Installation · San Rafael, CASan Rafael rain does not drizzle — it arrives a season at a time. Our gutter installation San Rafael team fits seamless gutters and downspouts sized for atmospheric rivers, so water leaves your roof fast and lands far from your foundation.
Sectional gutters leak at every joint. Ours are formed on site, to your exact roofline, with joints only where physics requires them — corners and downspouts.
Start with the inspection. You get photos, straight findings, and a written quote — no obligation.

Seamless, formed on site
This city averages 32–34 inches of rain a year (NOAA), and most of it falls between November and April — often all at once, in atmospheric rivers that test every inch of drainage a house has.
When gutters overflow, the water does not politely drip off the edge. It runs backward under the roof edge, soaks the fascia, and pools at the foundation line. Half the “roof leaks” and foundation worries we get called about started as drainage.
The system has four decisions in it. Here is how we make each one — and where we will talk you out of spending more.
Formed on site to the exact length of your roofline — no joints along the run, which means no joint leaks. Aluminum is the workhorse here: it does not rust in our bay air and takes paint to match your trim.
Five-inch gutters handle most roofs. Six-inch earns its cost on large roof areas, steep pitches that accelerate water, and tile roofs that shed fast and heavy. We measure your catchment and tell you which you actually need.
The gutter is only half the system. Enough downspouts, in the right places, sized to the gutter — and discharging away from the foundation, not at it. This is where most original systems in 94901 and 94903 fall short.
Under oak and bay canopy, guards genuinely help; they also do not make gutters maintenance-free, whatever the brochure says. We install them where the debris load justifies them and tell you where they do not.
A leaking corner, a pulled hanger, or one damaged run can often be repaired without replacing the system. If the metal is sound, we repair it and say why that is the better spend.
Gutter pricing is driven by measurement, not mystery — which is why we do not publish a made-up “average” for it. A gutter installation San Rafael quote from us is itemized in writing after we measure, and it turns on five things:
The total roofline being guttered, measured at your house — the single biggest factor in any gutter quote.
Two-story and hillside homes take more ladder work and more safety setup than a single-story ranch.
Five-inch vs six-inch, standard aluminum vs heavier gauge or copper — chosen for your roof’s catchment, not upsold.
How many, and where they discharge. Adding a downspout is cheap; foundation damage is not.
Gutters hang on fascia. If overflow has already rotted it, we show you the photos and price the repair as a separate line — never buried in the total.
Optional and priced separately, recommended only where your tree canopy justifies them.
Every gutter installation San Rafael homeowners book with us starts with the same fact: the rain here is measured in feet per season, and it all has to go somewhere.
Ask a Pro →Water that cannot get down the downspout goes sideways — under the roof edge, into fascia and soffits. Rotted fascia is one of the most common repairs we make, and it almost always started as a gutter problem.
In the Canal and other low-lying streets, water dumped at the foundation line is water looking for a way in. Correctly placed downspouts are the cheapest flood defense there is.
Low-slope Eichler roofs shed water slowly and at few points. A clogged or undersized gutter backs water up at exactly the seams foam roofs leak from. Terra Linda drainage has to work every time.
Canopy streets in 94903, low-lying streets in the Canal, tile roofs in the Dominican — drainage is designed per house, not per template.
Eichler country — low-slope foam and tar-and-gravel roofs, downspout seams, and recoats on the 94903 side of the hill.

Call (628) 202-3250 →It is measured, not averaged: linear feet of roofline, stories, gutter size and material, downspout count, and fascia condition set the price. A gutter installation San Rafael quote from us follows a free measurement at your house and is itemized in writing — you will see exactly what each line is for.
In our rain, yes. Sectional gutters join every ten feet or so, and every joint is a future leak and drip line. Seamless runs are formed to your roofline with joints only at corners and downspouts — fewer leaks, cleaner look, longer life.
Only if your roof sheds a lot of water fast: big roof planes, steep pitch, or tile. Many San Rafael homes are fine with 5-inch gutters and enough downspouts. We size from your roof’s catchment area during the free measurement and recommend the smaller system whenever it honestly does the job.
Twice a year is the baseline — after leaf fall and before the heaviest winter rain. Under heavy oak or bay canopy, three times is realistic. A pre-rain cleaning in October prevents most mid-storm overflow calls we get.
Often, yes — a leaking corner, a pulled hanger, or one damaged run can be repaired without replacing the system. If the metal is thinning or the pitch is wrong along the whole run, we will show you why replacement is the better spend before quoting it.
