Bayside flood zones and where your roof water goes
Parts of East Palo Alto near the Bay and along San Francisquito Creek are mapped in FEMA Special Flood Hazard Areas, and the creek spilled into nearby streets in February 1998. A roof does nothing to stop flood water, but on low, saturated ground every gallon off the roof has to go somewhere. We size gutters and downspouts to carry winter storms, keep discharge away from slab edges and crawlspace vents, and point out spots where water is pooling against the house.

Two-layer roofs from the County era sit on small lots here, so a tear-off has to be staged to keep debris off the house next door and the layer count confirmed first.

Post-war houses on small lots, and apartment roofs
Much of the city's single-family housing is post-war, on narrow lots where the next house is a few feet away. That shapes the job: ladders go up in tight side yards, tear-off has to be kept off the neighbor's roof, and debris bins often sit at the curb. Multifamily buildings bring a different roof altogether.
- Small post-war homes: low-pitch shingle roofs, sometimes with two layers, and short eaves that let water run down the siding.
- Duplexes and fourplexes: shared roofs where owners or a manager decide together, plus exterior stair landings that leak into units below.
- Apartment buildings: flat or low-slope roofs with drains and scuppers that clog, and older built-up roofing ready for flat roof repair or replacement.
East Palo Alto only incorporated in 1983, the newest city in San Mateo County, so most of its houses were built and first reroofed while the area was still under County rule. Records of earlier roof work can sit with the County rather than the city, and we treat an unknown layer count as something to confirm on the roof, not assume. The ground is low and open toward the Baylands, with few tall trees east of US-101, so sun and steady bay wind do most of the damage: brittle tabs, lifted ridge caps and loose edge metal. Winter rain from November to March then finds the short eaves and failed flashings at once, which is when drainage problems show up against the walls.

Four Corners, Bay Road and the Baylands edge
The city counted 30,034 residents at the 2020 Census on about two and a half square miles, so most addresses are a short run from the University Avenue or Willow Road exits off US-101. Four Corners, where Bay Road meets University Avenue, is the usual reference point when we describe a street, and Bay Road carries on east toward Cooley Landing, the city's bayfront park. Ravenswood Open Space Preserve and the Bay Trail edge the north side of town, which is where wind off the water reaches roofs first.
- Fire and sewer service: Menlo Park Fire Protection District covers East Palo Alto, and the East Palo Alto Sanitary District handles sewer lines, so downspouts must never be tied into a sewer cleanout.
- West of 101: the neighborhood between the freeway and San Francisquito Creek has the older trees and the creek-side drainage questions.
- Permits: the City of East Palo Alto Building Division issues them; we confirm parcel details before filing.
Proof we can offer without a local gallery
You won't find East Palo Alto project photos or neighbor testimonials here, because we don't have them and won't make them up. What is real: our crews already run this stretch of US-101 for Menlo Park and Palo Alto work, the Willow Road and University Avenue exits put us on any street in town quickly once we arrive, and we take on small repairs as readily as full reroofs. Commercial owners can ask about the leak repairs we have done on office and medical buildings.
