San Mateo Roof Pros provides professional gutters & downspouts in San Mateo, CA for residential and commercial properties across the Peninsula. Gutters on these lots are less a roofing question than a water-disposal question. Setbacks are tight, houses sit close to the line, and a downspout aimed at the fence is a conversation with a neighbor that starts politely and does not stay that way.
Volume is the other half of it. An atmospheric river delivers rain at an intensity that overruns a five-inch K-style trough fed by two outlets, and the surplus then goes over the back edge and straight down behind the fascia where nobody sees it for a decade. We size by plane area and rainfall intensity, which usually means six-inch trough fed by three-by-four downspouts on the larger slopes and at every inside corner.
On houses of this age the trough is only ever as good as what it hangs on. Fascia here rots from the back, fed by exactly the overflow described above, so gutter work and fascia repair get quoted together as one scope. Skip that and the new gutter is screwed to soft wood, and it sags visibly within two winters of the day it was hung.
Discharge is the part most installers skip entirely. A splash block at the base of a downspout simply puts the water back against a foundation on a lot that has no room to spare. Solid pipe carried out to the street, or into a properly sized drywell where the soil will actually accept it, is the fix, and it has to terminate somewhere that is not the property line or your neighbor's yard.
Materials are unremarkable and we keep them that way on purpose. Point-oh-three-two aluminum on exposed runs where ladders and branches reach them, hidden hangers driven into the rafter tails at two-foot centers rather than spikes through end grain, mitered corners riveted and sealed instead of caulked, and half-round in copper where a period house already has it and deserves to keep it.
On guards we will disappoint you. Foam inserts and fine mesh both clog under these trees, just more slowly and far more expensively than an open gutter does. A reverse-curve system works on some profiles and sheds water straight past the trough on shallow pitch. Under most of these roofs the honest answer is two cleanings a year and no product at all bolted to the front.
Our licensed and insured team brings the right materials and equipment to every job — Class B roof assemblies tested to ASTM E108, concealed-clip twenty-four-gauge Galvalume standing seam, dry-fix hip and ridge systems for clay barrel profiles, granule-surfaced SBS cap sheet over a self-adhered base ply, sixty-mil mechanically attached TPO over tapered polyisocyanurate, half-inch plywood re-sheathing over one-by-six board decking — and backs the work with a written workmanship warranty. We serve San Mateo and nearby communities including Burlingame, Millbrae, Hillsborough, Foster City.

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 B roof assemblies tested to ASTM E108, concealed-clip twenty-four-gauge Galvalume standing seam, dry-fix hip and ridge systems for clay barrel profiles, granule-surfaced SBS cap sheet over a self-adhered base ply, 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 San Mateo 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 Peninsula means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
