Pomona Roof Pros provides professional gutters & downspouts in Pomona, CA for residential and commercial properties across the Pomona Valley. A lot of Pomona houses were built without gutters and are still without them, and that was not always a mistake. Before you spend, it is worth deciding whether this house actually needs them, because in a low-rainfall valley the answer is sometimes no. We say so when it is.
Where they clearly earn their money: any eave that drips onto a walkway, a porch slab or a foundation on the uphill side of the lot. Any wall with stucco or wood siding taking splash-back. Any plane above a lower roof, where concentrated runoff scours granules off the shingles below within a few winters. Any house on a slope where water has nowhere to go but back toward the building.
Where they do not: a short eave with a generous overhang over planting beds on the downhill side, on a house whose real drainage problem is grade rather than roof water. Adding a hundred feet of gutter nobody cleans is a way to hold wet leaves against your fascia for eleven months of the year. Wet leaves against wood fascia is how the rot we spend most of our time repairing begins.
When we do install, we run continuous K-style aluminum gutters formed on site. Five inch on most residential eaves, six inch with three-by-four downspouts on long runs, steep planes, and anything collecting from an upper roof. Hidden hangers screwed into the fascia at two feet on center, not spikes and ferrules, and a genuine slope to the outlet rather than a nominal one. Color-matched, and mitred at the corners rather than butted.
The downspout is the part people get wrong. Water has to leave the building, so we take it to a splash block clear of the foundation or into solid pipe run out to daylight or the street. A downspout discharging beside a slab is a gutter that moved the problem four feet. On the uphill lots that is the difference between a dry crawlspace and a wet one.
Gutters also depend on the fascia they hang from, which on the older houses here is often the thing actually failing. We will not screw new gutter into soft fascia. That work gets quoted first and honestly, because hanging metal on rot is how a gutter job becomes a framing job. Better to know that on day one.
Our licensed and insured team brings the right materials and equipment to every job — architectural laminated shingles with six-nail fastening, SBS polymer-modified asphalt shingles, 1x6 spaced sheathing overlaid with half-inch plywood, two-ply modified bitumen with a granulated cap sheet, salvaged mission and S-profile clay barrel tile, 24-gauge standing seam with concealed sliding clips — and backs the work with a written workmanship warranty. We serve Pomona and nearby communities including Claremont, La Verne, San Dimas, Diamond Bar.

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 architectural laminated shingles with six-nail fastening, SBS polymer-modified asphalt shingles, 1x6 spaced sheathing overlaid with half-inch plywood, two-ply modified bitumen with a granulated cap sheet, 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 Pomona 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 the Pomona Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
