Most Bay Area homes are well served by a standard architectural shingle: Owens Corning Duration or CertainTeed Landmark. The step-up lines are mostly about looks, so choose them if you love how they look. A warranty describes coverage, and that's a different number from how long a roof actually lasts. And color is where most people get stuck, so it gets its own section below.

Shingle shopping gets overwhelming fast. Every manufacturer has four or five lines, each line has twenty colors, and every brochure says "lifetime." We've been putting roofs on Bay Area houses since 1989, so here's how we'd walk a friend through it.
Start with the standard architectural shingle
Our bids start with Owens Corning Duration or CertainTeed Landmark. Both are architectural shingles, the thicker, dimensional style that's become the standard on Bay Area homes. They're what we install on most of the roofs we do, and they're what we'd put on our own house.
Duration and Landmark are close enough in cost that we price them the same. Pick whichever brand's colors or nailing strip you like better.
What the upgrades actually buy
From the standard line you can step up. Here's what each step gets you:
- Thicker architectural: Owens Corning Duration Max or CertainTeed Landmark PRO. Extra layers for more depth and a bolder shadow line.
- Wood shake look: Owens Corning Woodcrest or CertainTeed Presidential Shake. Looks like hand-split cedar, without the fire risk or the upkeep of real wood.
- Heaviest shake style: Owens Corning Woodmoor or CertainTeed Presidential TL. The thickest, most dramatic option in either line.
In our experience, the step-ups don't make a roof last longer, and they carry the same manufacturer warranty as the standard line. Your homeowners insurance won't give a thicker shingle extra years either. Many insurance companies look closely at roofs older than 15 to 25 years, upgrade or not. The heavier shake styles also take more labor. They're heavier to carry up, harder to cut, and need a different starter course along the edges, and that's part of why they cost more.
So the honest reason to choose one is the look. That's a perfectly good reason. A house is something you look at every day, and if the Woodcrest profile is what makes your place look right to you, it's worth paying for. If you're on the fence, the standard line gives you the same protection for less.
Cool Roof: what it does for your house
Every line we install comes in a Cool Roof version from both manufacturers. A Cool Roof shingle is made to reflect more of the sun's heat.
What that gets you:
- A cooler attic. Less heat soaks through the roof deck. During peak summer heat that can bring the rooms below down by a degree or two.
- Possibly less wear. Shingles that don't heat up as much may go through less of the daily expand-and-contract cycle that ages a roof.
- A cooler block. When enough homes on a street have reflective roofs, the whole neighborhood runs a little cooler. Planners call this the urban heat island effect.
- One route to Title 24. A Cool Roof is one way to meet California's energy code. Good attic insulation and ventilation are another way.
Cool Roof versions cost a bit more. If your main goal is a noticeably cooler house, attic insulation and ventilation usually make the bigger difference, and we're happy to talk through both. If you like the idea of a cooler attic and a cooler street, Cool Roof is a solid choice.
How long a roof lasts, and what the warranty covers
These are two different questions, and roofing marketing tends to blur them.
How long it lasts. A well-installed architectural shingle roof in the Bay Area usually lasts about 20 to 30 years. Sun exposure and attic ventilation make the biggest difference. A south-facing slope over a hot, stuffy attic wears out faster than a shaded slope over a well-vented one.
What the warranty covers. Every line we install carries the manufacturer's lifetime limited warranty. "Limited" matters: full coverage runs for the first 10 years, and after that it's prorated, so the coverage shrinks as the roof ages.
The 50-year option. Because we're an Owens Corning Preferred Contractor, we can register your roof for an Owens Corning extended warranty that covers your materials for 50 years, non-prorated, for a small added cost. To qualify, the roof has to be built as a complete Owens Corning system, with matching starter strips, underlayment and ridge caps, plus balanced attic ventilation. We specify all of that when you choose it.
Fifty years is how long the coverage runs. It doesn't mean the shingles will last 50 years on your roof. You'll hear "50-year roof" from some salespeople, and it's worth asking what exactly the 50 years refers to.
Our workmanship warranty. On top of whatever the manufacturer covers, our own workmanship warranty covers the installation for 10 years.
Choosing a color you'll still like in ten years
Color is where good decisions stall. It makes sense. You'll look at this roof every day for twenty-plus years, and the samples make it harder than it should be.
Why the sample doesn't match the finished roof:
- Samples are small. A 6-inch chip can't show you how a blend reads across 2,000 square feet. Blends with a few dark and light granules look busier up close and flatter from the street.
- Screens shift color. The same "Driftwood" looks different on your phone, your laptop and the manufacturer's website.
- Sun changes everything. A gray that looks cool and even in the shade can pick up warm tones in afternoon light. If "no brown in my gray" is a must, say so, and we'll show you blends that hold up to it.
What works better:
- Look at finished roofs. Ask us for a house nearby with the exact product and color name you're considering, then drive by at the time of day you'll usually see your own.
- Think about the rest of the house. Gutters, trim and future paint colors all sit next to the roof. New pipe boots and vents get painted to match the shingles.
- Narrow to two, then decide. Most people get stuck with five finalists. Two is manageable.
Color never changes the price. Every color in the line you choose costs the same.
What to check on any bid
Whoever you hire, the shingle part of the bid should spell out:
- The manufacturer and the full product name, like "Owens Corning Duration" or "CertainTeed Landmark PRO." "Architectural shingle" on its own isn't enough.
- The color, by the manufacturer's name.
- Whether the matching layers are specified: starter, underlayment and ridge caps from the same manufacturer, if you want the extended warranty.
- Both warranties: the manufacturer's, including which tier is being registered, and the roofer's own workmanship warranty, with its length.
