Why Crestview Roofing Is Redwood City’s Preferred Roof Installation Company

We’ve built our Redwood City reputation on a process that matches how you actually live: you get a live trackable arrival time, a written price before any work begins, and before-and-after photos of the job site. That’s The Relay Standard, and it’s the backbone of every Roof Installation we complete. Dylan Pace leads our install teams personally, walking homeowners through the scope, the materials, and the permit path before a single shingle is set.

Redwood City homeowners consistently tell us the difference comes down to visibility. You’ll know exactly who’s arriving, when they’ll pull up, and what documentation you’ll get after. We use GAF, CertainTeed, and Owens Corning shingles, and we never quote one number and bill another. Every job, including all trim, flashing, and underlayment work, gets a written quote up front. Every repair is covered by the 365-Day Done Right Promise, in writing, included at no extra cost. Scheduling and dispatch for our Redwood City crews are coordinated from our San Francisco Bay Area office.

Roof Flashing Installation in Redwood City

Roof Flashing Installation in Redwood City is the difference between a roof that leaks in the first winter storm and one that holds for decades – flashing is the metal strips that seal the joints around chimneys, skylights, vents, and the edges where your roof meets a wall. On many Redwood City homes, especially 1940s and 1950s ranchers in Woodside Plaza and Redwood Village, original flashing has been reused through two or three re-roofs and quietly corroded through. We replace it rather than patch it.

You need new flashing when: you see rust blooms or lifted edges around penetrations, you’re getting water stains on the ceiling below a chimney, or you’re already doing a full tear-off and the old metal is wavy and pitted. On a typical Redwood City re-roof, new flashing runs roughly $900 to $2,200 depending on how many penetrations and valleys your roof has, and it’s part of every Crestview installation scope. We don’t treat it as an upcharge line item surprise.

Valley and chimney flashing

Valleys collect runoff from two roof planes and push it hard. In Redwood City’s wet winters, a poorly flashed valley leaks within months, not years. We use 26-gauge galvanized or painted aluminum, cut to fit your roof’s actual pitch, not bent on-site leftovers. Chimney flashing gets stepped into the mortar joints and sealed with a polyurethane caulk that flexes with the Peninsula’s seasonal movement. Expect a chimney to add $450 to $900 to the flashing portion of your install.

Drip edge and eave protection

Drip edge is the thin metal at your roof’s lower edge that directs water into the gutter instead of back onto the fascia. Older Redwood City homes often have none, or it’s rusted through. We include new drip edge on every full installation, and we inspect the fascia behind it because rotted fascia on 1930s bungalows is common. That replacement runs $8 to $16 per linear foot when needed, and you’ll see it called out on our written estimate before we start.

TPO Roofing Installation in Redwood City

TPO Roofing Installation in Redwood City is what we recommend for the low-slope and flat sections you find on mid-century additions, sunrooms, and a lot of Eichler-style and ranch homes east of El Camino Real. TPO stands for thermoplastic polyolefin, a heat-welded single-ply membrane that holds up against ponding water and reflects heat. If your roof has a section with less than a 2:12 pitch, standard shingles won’t shed water properly there, and TPO is the right call.

On Redwood City homes, TPO sections typically run $8 to $12 per square foot installed, including new insulation board if the old one is waterlogged – and on flat sections with poor drainage, it often is. We heat-weld the seams rather than glue them, which is the single biggest factor in preventing peel-back failures on low-slope areas. A typical 400-square-foot flat section, fully stripped and re-membraned, runs $3,200 to $5,000.

TPO on additions and sunrooms

Sunroom and addition roofs in Redwood City are notorious for being afterthoughts. Builders often roof them with rolled asphalt, which cracks within a decade under Peninsula sun. We convert those sections to TPO with tapered insulation to direct water to the drains, which fixes both the leak and the ponding problem. Most conversions are two to three days for a crew.

Heat-welded seams vs. glued seams

Glued TPO seams fail. It’s the number one reason homeowners in Redwood City call us after a “bargain” flat roof install. Heat-welding fuses the membrane chemically, creating a bond stronger than the sheet itself. We only use heat-welded TPO, and we photo-document the seams as part of our before-and-after record you receive.

Trusted Brands We Service in Redwood City

We install and service GAF, CertainTeed, and Owens Corning roofing systems in Redwood City, and we have strong opinions about which product fits which house. A 1960s ranch in Redwood Village does well with a CertainTeed Landmark shingle. A two-story craftsman in Mount Carmel often looks better with a GAF Timberline HDZ in a warm cedar tone. We don’t push one brand. We spec what fits your roof’s pitch, your home’s style, and your budget. Because our Redwood City crews pull materials from our Bay Area supply chain, most specialty order inventory – including TPO membrane and custom flashing – arrives within two to three business days. You get a written warranty summary with your final paperwork.

Common Roof Installation Problems We See in Redwood City Homes

These four issues show up on Redwood City installs more than anywhere else we work on the Peninsula. Here’s what they are and what we do about them.

• Skip sheathing left uncorrected. Homes built before 1980 often have spaced 1×6 decking rather than solid plywood. Stripping the old roof and nailing shingles onto that gappy deck creates a wavy surface that voids GAF, CertainTeed, and Owens Corning warranties. We re-deck over skip sheathing with solid CDX plywood before laying underlayment, and we show you photos of that step specifically.
• Missing fire-rated underlayment on wood-shake conversions. Redwood City code requires a fire-rated layer and often a Class A assembly when you convert a wood-shake roof to composite shingles. Out-of-town crews skip this, the city fails the inspection, and the homeowner is left holding a half-finished roof. We pull the permit, know what the inspector checks, and install the required layers the first time.
• Reused drip edge and old flashing. Some installers cut costs by leaving existing drip edge in place. On Redwood City’s flat-to-pitched transitions, that old metal is the first thing to leak. We replace drip edge on every full tear-off and every penetration gets new flashing, with line items in your written quote.
• Ventilation blocked after re-roofing. Older Peninsula homes often had minimal intake venting to begin with. If we don’t correct that during the install, your attic cooks in Redwood City summers and your shingles age early. We calculate net free vent area by roof section and add intake and exhaust ventilation where your roof math says it’s needed.
