Concord Roof Pros provides professional gutters & downspouts in Concord, CA for residential and commercial properties across central and east Contra Costa County. Concord rainfall arrives in an awkward shape for gutters: about twenty-four inches a year, nearly all of it in a few winter months, with a one-day record of almost four inches. A gutter here sits dry for half the year, then moves all of it at once.
That argues for capacity and for cleaning schedules rather than gadgets. On steep slopes and long runs we size up to six-inch K-style with three-by-four downspouts instead of the builder-standard five-inch, because the real failure mode in a hard December cell is water overshooting the front lip and dumping straight at the foundation. Under valley oaks we add screens, with the honest caveat that no guard eliminates cleaning; it turns a shovel job into a rinse.
We hang K-style aluminum in continuous runs formed on site, so the only joints are at corners and outlets rather than every ten feet. Aluminum in .032 rather than .027 for anything over twenty feet, hidden hangers screwed into solid fascia at roughly two feet on center, and slip joints where a run gets long enough for real thermal travel. Metal expands here every afternoon like everything else on the roof.
Where the water goes matters more than most homeowners are ever told. Contra Costa clay soils swell as they take on water and shrink as they dry, and that movement is unkind to foundations, walkways and patio slabs. A downspout discharging at the base of a wall is feeding that cycle every storm. We run solid extensions well clear of the structure or tie into drain lines that carry it away, and we check where those lines go.
Before hanging anything we look at what we are hanging it on. Fascia that has softened from years of overflow will not hold a hanger under a full gutter, and screwing new aluminum onto bad wood is a callback with a date on it, so trim repair comes first and gets priced honestly rather than discovered on install day.
Timing advice, freely given: get the gutters cleared in October. A sizeable share of the emergency calls we take in the first big storm of the season are not roof failures at all. They are full gutters backing water up under the first course of shingles and into the eave.
Our licensed and insured team brings the right materials and equipment to every job — Class A fire-rated shingle assemblies, SBS-modified bitumen cap sheet, ASTM C920 high-movement joint sealant, floating expansion clips on standing seam, 24-gauge Galvalume panel, reglet-cut counterflashing — and backs the work with a written workmanship warranty. We serve Concord and nearby communities including Pleasant Hill, Martinez, Walnut Creek, Clayton.

Materials, equipment and how we do gutters & downspouts
The difference between gutters & downspouts that lasts and gutters & downspouts that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with Class A fire-rated shingle assemblies, SBS-modified bitumen cap sheet, ASTM C920 high-movement joint sealant, floating expansion clips on standing seam, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Concord job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in central and east Contra Costa County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Concord Chooses Concord Roof Pros
- ✓Estimates come from on the roof and in the attic, never from the driveway or from a satellite measurement alone.
- ✓We specify high-movement joint sealant and reglet-cut counterflashing, because asphalt mastic does not survive a daily temperature swing.
- ✓Long metal runs get floating clips and concealed fasteners, so panels can move without wallowing out several hundred screw holes.
- ✓Tile roofs get quoted as a lift-and-relay first, since the underlayment is what expired and the tile itself usually has decades left.
