Most siding brands make one kind of product. CertainTeed makes several, which is why it deserves its own conversation rather than being lumped in with "vinyl." Under one manufacturer you can get standard and premium vinyl, insulated vinyl, polymer shakes and shingles, and even fiber cement — so for a Moraga homeowner who likes the idea of a single brand and warranty program but wants to choose the right product for a particular elevation, CertainTeed is a flexible starting point. Bay Area Siding Company is a Larkspur-based siding and window contractor, and we install CertainTeed's lines across Lamorinda.

The lineup, and how to think about it

CertainTeed's range covers most of the ways you might re-side a Moraga home:

• Vinyl — the Monogram and Mainstreet lines are the workhorse clapboard/dutch-lap panels in a broad palette, and Cedar Impressions delivers a molded shake-and-shingle look for gables, accents, or a full shingle-style elevation without the upkeep of real cedar.
• Insulated vinyl (CedarBoards) — a foam-backed panel that stiffens the board, resists impact, and adds a modest thermal break; this is where the former Craneboard insulated product now lives in CertainTeed's catalog.
• Polymer shakes and shingles — a step up in realism and durability over standard vinyl shake profiles, good for a hillside home that wants texture.
• Fiber cement (WeatherBoards) — CertainTeed's noncombustible, cement-based plank, worth a look where the material category matters more than the vinyl economics.

That last point is the important one in this town. If your home is on Moraga's eastern or northeastern hills or backs onto open space, the material category may matter more than the brand — see the "which product" note below.

Warranties and finish

CertainTeed's siding lines carry strong warranty coverage — the vinyl and polymer products are generally backed by lifetime limited warranties, and the fiber cement line has its own program. We install to the manufacturer's specifications so the coverage holds; the exact terms, transferability, and any fade-coverage details are best confirmed against CertainTeed's current warranty documentation for the specific line you choose rather than a figure quoted here.

Which CertainTeed product for a Moraga parcel

Moraga sits in the Moraga-Orinda Fire District, and its hill and open-space-adjacent parcels fall within the fire hazard severity zones on the updated 2025 Cal Fire maps. On a parcel carrying a fire-hazard designation, California Building Code Chapter 7A can govern regulated exterior assemblies — and there, CertainTeed's fiber cement (WeatherBoards) or another noncombustible fiber cement is the sensible pick, not the vinyl or polymer lines, which are combustible. Whether Chapter 7A applies to your address depends on the parcel and scope, which we confirm with the Town and the fire district. On lower valley-floor lots away from the wildland edge, the vinyl and insulated-vinyl lines are on the table and often the value winner. We help you land on the right product, not just the right brand.

Install done right

We re-side by removing the old cladding to the sheathing and substrate, then inspecting and renewing the water-resistive barrier and flashing before the new material goes on — the wall bases and older window openings on Moraga's shaded, damp canyon walls are where problems hide. Framing behind the sheathing is only involved if the sheathing itself has failed, a larger scope we would flag first. Permits run through the Contra Costa County Department of Conservation and Development, with Town Planning or Engineering sign-off on most exterior work; we handle the coordination.

What drives the cost

The product line you choose (insulated and polymer products cost more than standard vinyl; fiber cement more again), the number of stories and the trim detail, how much substrate repair the tear-off reveals, and access on a hillside versus a flat lot. We price the specific home rather than posting a rate.

FAQ

Is CertainTeed a vinyl brand or a fiber cement brand? Both, plus insulated vinyl and polymer shakes. That range is the point — under one warranty program you can pick the vinyl, insulated, polymer, or fiber cement product that fits your elevation and your parcel.

Which CertainTeed product should I use near the Moraga hills? On a parcel with a fire-hazard designation, the noncombustible fiber cement (WeatherBoards) line, not the combustible vinyl or polymer products. Whether Chapter 7A applies depends on your parcel and scope, which we confirm with the Town and the Moraga-Orinda Fire District before speccing.

What happened to Craneboard? CertainTeed's insulated vinyl line, CedarBoards, is where that insulated product now sits. It is a foam-backed panel that adds rigidity, impact resistance, and a modest thermal break over hollow-back vinyl.

Can CertainTeed match a cedar-shingle look without the maintenance? Yes — Cedar Impressions (molded vinyl shake/shingle) and the polymer shake lines give you the texture of cedar on gables or a full elevation without the paint, rot, and pest upkeep of real wood.
