Roofing Redwood City

Hiring a roofer in Redwood City, where every tear-off has a recycling plan

Redwood City lists all roofing among the projects its construction and demolition debris ordinance covers, so a re-roof starts with a Waste Management Plan in the city's Green Halo system before the permit is issued. At least 65 percent of the old shingle, shake or tile has to be kept out of the landfill, with receipts filed after the final. Every Redwood City ZIP code sits in Energy Code Climate Zone 3, outside the state's re-roof cool-roof rules.

The houses here

A pre-war core, hillside tracts and a bayfront built in the 1960s-80s

The city's General Plan describes Redwood City growing outward from downtown in rings. Mount Carmel, northeast of Wellesley Park and southwest of El Camino Real, has more than 40 percent of its housing from before World War II, and the Bohemian Club re-subdivided Wellesley Park itself after the 1906 earthquake. Population jumped from 12,500 at the start of the war to more than 46,000 by 1960, pushing tracts such as Woodside Plaza and Farm Hill up into the hills. Then, after annexing 25 square miles of tidelands and salt ponds east of U.S. 101 in the mid-1960s, the city grew Redwood Shores, with homes and condominiums built from the 1960s through the 1980s. Much of the Shores sits inside owners associations, which brings a second approval into most roof jobs there.

The work

What a Redwood City re-roof involves beyond the shingles

  1. The tear-off and its Green Halo plan

    The city's debris program packet, revised January 2026, says roofing projects that replace wood shake, tile, concrete, asphalt or composite must divert at least 65 percent of the debris they generate. The plan is opened in Redwood City Waste Tracking before the permit issues, and staff size a deposit from the roof's square footage using a waste generation factor set for re-roofs. Every weight tag from a recycling or disposal facility has to be coded to show whether the load was recycled or dumped.

  2. Re-roofing ahead of a solar array

    Redwood City's photovoltaic checklist, revised January 2026, says arrays should be mounted on one layer of asphalt shingles and that the roofing should equal or exceed the life of the panels. Where the existing covering weighs more than five pounds per square foot, heavy wood shake or slate for example, it asks for structural calculations from an engineer or architect, and the modules and racking must carry a Class A listing to UL 1703. A roof near the end of its life is therefore best replaced before the panels go up.

  3. Low-slope roofs in Climate Zone 3

    Membrane and other low-slope roofs are where cool-roof rules bite in warmer zones. In Climate Zone 3 they do not: the Energy Code's reflectance rule for replaced low-slope roofs lists Zones 4 and 6 through 15, and its table of added roof insulation marks Zone 3 as not required. A flat-roof replacement here is chosen on durability, drainage and what the association allows, not on a state reflectance number.

  4. Finding a place for the debris box

    The Building Division's FAQ is blunt: dumpsters, PODs and similar containers may not be placed on the street at any time, and anything that is not on wheels must stay on site, in the driveway or yard. On a lot with a short driveway or a shared one, that can decide how the old roofing leaves. Where there is no room, the city suggests a dump truck or another mobile way of hauling it off.

Permits and local rules

Ordinances and city policies a Redwood City roofer works under

  1. Construction and demolition debris recycling

    The Building Division lists the projects with recycling requirements as all new construction, all demolition, all roofing, and other projects valued at a set threshold or more. A covered project submits its Waste Management Plan through Redwood City Waste Tracking before the building permit is issued, then files a Debris Disposal and Diversion Report and recycling receipts. The packet sets 60 calendar days after final inspection for that report; miss it, and some or all of the deposit can be kept, with penalties under Municipal Code Section 9.200.

  2. Permits for homes inside an owners association

    A Building Division policy revised in September 2026 points out that an association may have legal rights over what is built through its CC&Rs, and recommends that plans already approved by the association go in alongside the plans sent to the city. The approval letter should be stamped Approved, with the date and the printed name and signature of the person authorized to approve, and should state the approved scope of work. Revisions go back to the association before they reach the city.

  3. The residential solar checklist

    For a roof-mounted system the city wants an electrical roof plan, elevations showing the array's height from the ground, wind load calculations for the whole mounting system, and a roof framing plan giving rafter size, length and spacing, purlins, sheathing, pitch and the type of roof covering. The same checklist is where the one-layer shingle expectation, the five-pound weight trigger for structural calculations and the Class A listing appear. The Building Division's FAQ names its plan review appointment, where staff can approve a project while the applicant waits, as the fastest way to a solar permit.

Part by part

Two parts of Redwood City with a second set of rules

  • Redwood Shores

    Any exterior change to a property in ZIP code 94065 needs approval from the design review board that governs it before construction starts. For homes built since 1981 that is the Modifications Committee of the Redwood Shores Owners Association; for older homes, mostly west of Shell Parkway, it is the Architectural Design Board of the Redwood Shores Community Association. A new roof color or material counts.

  • Emerald Lake Hills

    The hills carry Redwood City addresses but are unincorporated, so the re-roof permit comes from San Mateo County Planning and Building. The county's process has its own paperwork: the contractor signs a form naming the roofing's manufacturer and product and certifying a Class A or Class B assembly, and skipping the tear-off inspection takes a waiver, signed by owner and contractor, that goes on the public record.

Timing

Weekdays only, unless the paperwork starts a month ahead

Contractors may work from 7 a.m. to 8 p.m., Monday through Friday. Saturday, Sunday and city holidays are off limits to them unless the Building Division gives written approval, and the request form asks for more than a signature: neighbors within 500 feet must be notified 30 days before the work, with a copy of that letter attached, and noise-producing work on an approved day runs from 9 a.m. to 4 p.m. Inspections happen between 8 a.m. and 4 p.m., and the inspector calls with a two-hour window.

Before you hire

Questions for a Redwood City roofer before you sign

  • Who opens the Waste Management Plan in Redwood City Waste Tracking, and who files the receipts within 60 days of the final inspection?
  • Where will the debris box or trailer sit, given that Redwood City allows none on the street?
  • For a Redwood Shores home, which design board approves the roofing, and will its stamped letter go in with the permit application?
  • If solar is coming, will the new roof be a single layer of asphalt shingles rated to outlast the panels?
  • Look up the C-39 Roofing license at cslb.ca.gov, and ask whether the firm has done the city's debris paperwork before.

Questions

What Redwood City owners ask about re-roofing

Do Redwood City re-roofs have to use cool-roof products?

Not under the state's rules for replacement roofs. Every Redwood City ZIP code is in Climate Zone 3, while the Energy Code's reflectance requirement for steep roofs names Zones 4 and 8 through 15 and the one for low-slope roofs names Zones 4 and 6 through 15. An association can still set its own color or material rules.

What happens if the recycling report is late after our Redwood City re-roof?

The debris program packet says that if the requirements are not met, including a final report within 60 calendar days of final inspection, the deposit or part of it will not be returned, and the applicant is subject to the penalties in Municipal Code Section 9.200. Weight tags have to show whether each load was recycled or disposed, so keep them from the first day.

Our Emerald Lake Hills house has a Redwood City address. Who inspects the roof?

San Mateo County does. The county's re-roof permit can be applied for online or by mail, and a tear-off inspection is part of it unless the owner and contractor both sign a waiver. That waiver records that the sheathing and framing were never inspected, is open to future buyers and lenders, and does not excuse a nailing inspection if new sheathing goes on.

Where does the debris bin go during a Redwood City tear-off?

On your property. Redwood City does not allow dumpsters, PODs or similar containers on the street at any time, and anything that cannot be wheeled away has to be stored on site, on the driveway or in the yard. If there is no room, the Building Division suggests hauling the old roofing off in a dump truck or by some other mobile means.

Does an old shake roof have to come off before we add solar?

Often it does. Redwood City's solar checklist says arrays should be mounted on one layer of asphalt shingles and asks for structural calculations from an engineer or architect when the existing roof covering weighs more than five pounds per square foot, naming heavy wood shake and slate as examples. Re-roofing first avoids lifting the panels later.

Where these facts come from

Checked against these public sources in October 2026. Rules and programs change: confirm permit requirements with the city before work starts, and a contractor's license on the CSLB website.
