How do I choose a roofing company in Palo Alto, especially for an Eichler?

Short answerChoose a C-39 licensed company with proven low-slope experience if you own one of Palo Alto's many Eichlers, because those roofs need foam or single-ply systems that meet the strict low-slope cool-roof target in climate zone 4. Older homes in Professorville and Old Palo Alto need a different crew. Request a free written estimate below.

Why does Palo Alto need two kinds of roofer?

Palo Alto's median home was built in 1963 (ACS 2024 5-year), and its two biggest roof families couldn't be more different. Eichler neighborhoods such as Greenmeadow, Fairmeadow and Charleston Meadows have flat and low-slope roofs with exposed beams and skylights. Older neighborhoods, Professorville, Old Palo Alto and Crescent Park among them, have steep pitched roofs, sometimes historic. A company that excels at one may rarely do the other, so ask.

What should I verify before hiring in Palo Alto?

Three things, all on the state's license lookup: the license is active, it carries the C-39 roofing class (C-39 details), and workers' comp is listed if the crew are employees. Then read the written contract: California caps the down payment on home improvement work (Business and Professions Code 7159.5).

What should an Eichler roofer explain?

  • Which system: spray foam with a coating, or a single-ply membrane over rigid insulation (South Bay Eichler guide)
  • How they keep the thin roof edge and exposed beams looking right
  • How skylights, gravel stops and drains are handled
  • The low-slope cool-roof product: in climate zone 4 (CEC) the low-slope target is much stricter than for shingles (CEC guide)
  • Recoat or maintenance intervals and what voids the warranty

Permits and historic homes

The city's Building division issues reroof permits. If your house is a listed historic resource or in a historic district, ask the city whether a change of roofing material needs review first; like-for-like is usually simpler. Homes west of Foothill Expressway border open space, so check CAL FIRE's map.

What about cost?

We keep prices on a separate page: what drives a new roof's price in Palo Alto. The short version is that roof size, pitch, material, tear-off layers, decking and access decide it, so the free written estimate is where your actual number comes from.

Which local conditions should a Palo Alto reroof plan for?

At the Palo Alto station, the 1991-2020 normals show 15.1 inches a year, with 60% in the three winter months and roughly 12 days at 90 degrees or more (NOAA). Parts of Palo Alto are rated Very High on CAL FIRE's 2025 recommended map; inside those areas, Class A is mandatory once more than half the roof is replaced (HSC 13132.7). Look up your own parcel on CAL FIRE's map.

Frequently asked questions

Is a cool roof required on a Palo Alto Eichler reroof?

Usually. Palo Alto is in climate zone 4, where replacing more than half of a low-slope roof generally requires a product meeting the low-slope cool-roof standard.

Foam or membrane for my Eichler?

Both work when done well. Foam adds insulation and seamless coverage; single-ply over rigid insulation is a common alternative. Ask for each bidder's system and warranty.

Do historic Palo Alto homes need approval for a new roof?

It depends on the home's status and the change. Ask the city before switching materials on a listed or district property.
