Wood shake roof replacement is one of the most common upgrades on older Orange County homes. Aging cedar shakes split, curl and dry out in our sun, they're a known wildfire risk, and they can make insurance harder to keep. The good news: several Class A fire-rated materials now give you a similar rustic, layered look.

Why Orange County homeowners are replacing wood shake roofs

Fire risk and local rules

Untreated wood shakes are combustible, and wind-driven embers are one of the main ways homes ignite during wildfires. Parts of Orange County, including canyon and foothill neighborhoods near Laguna Beach, Orange, Yorba Linda and the Saddleback Valley, fall within designated fire hazard severity zones, where California requires fire-resistant roof coverings on new roofs and many replacements. Many cities have their own restrictions as well. Your city's building department has the final say for your address.

Insurance pressure

Some homeowners first hear about their shake roof from their insurer, whether that's a non-renewal notice, an inspection request or a requirement to replace. Replacing with a Class A material can make those conversations easier, though every carrier sets its own rules.

Plain old age

Even well-kept shakes wear out. Look for splits running down the grain, cupped and curled pieces, missing shakes, moss or dark rot on shaded slopes, and daylight visible from the attic. Once shakes are brittle, repairs tend to break neighboring pieces.

If your shake roof is showing its age, book your roof diagnosis online and we'll document its condition before you decide anything.

Class A materials that keep the shake look

Our article on Class A fire-rated roofing in California explains the rating system. Here's how the main alternatives compare for a shake-style home.

Architectural composition shingles

Thick, dimensional asphalt shingles come in wood-tone color blends and shadow lines that echo shakes. Many are Class A rated.

When shingles make sense

They're a good fit for homeowners who want a lighter roof, a shorter installation and a familiar material, and whose HOA accepts composition.

Concrete tile in a shake profile

Flat concrete tiles are made with textured, split-wood surfaces and are Class A. They're heavy, so the roof framing needs to be checked. Lightweight concrete tiles exist for homes that can't carry standard tile.

When tile makes sense

Tile suits homeowners planning to stay for many years who want a durable, fire-resistant surface and whose structure can support the weight.

Stone-coated steel and composite shakes

Stone-coated steel panels are pressed into shake shapes and coated with granules. Synthetic composite shakes mimic cedar closely. Fire ratings vary by product and installation system, so confirm the Class A listing for the exact system you choose.

How a wood shake roof replacement works

Tear-off, not overlay

Shakes should be removed completely. Layering new material over them traps an uneven, combustible layer and hides the deck. Our guide to tear-off vs. overlay explains why this matters for any replacement.

Solid decking over skip sheathing

Many shake roofs were installed over spaced boards, called skip sheathing, which let the wood breathe. Most modern materials need a solid deck, so plywood or OSB is typically installed over or in place of the spaced boards. This is also when damaged framing is found and repaired.

Underlayment, flashing and ventilation

New synthetic underlayment goes down; we don't use felt. Valleys, walls, chimneys and skylights get new flashing. It's also the right time to look at attic vents: ember-resistant vents are part of hardening a home against wildfire.

Installation and cleanup

Shake tear-offs create a lot of debris and splinters. Expect tarps over landscaping, magnetic sweeps for nails and a final walkthrough.

Permits and final sign-off

A full replacement normally requires a building permit, and the city inspector may check the deck and the finished roof. Keep the permit card and final sign-off with your home records; insurers and future buyers often ask for proof that the old shakes are gone and a rated roof is in place.

What shapes the scope of your replacement

Every shake roof is different, so we don't publish prices. Instead, the estimate reflects a few things you can see for yourself: the size and pitch of the roof, how many valleys, skylights and chimneys it has, whether solid decking must be added over skip sheathing, how much hidden rot turns up, and the material you choose. Tile may also call for an engineering check. Your Roofing Advisor will explain each of these line by line.

Questions to ask before you choose

  • Does my address fall in a fire hazard severity zone, and what does my city require?
  • Can my roof framing carry tile, or should I look at lighter options?
  • Does my HOA have an approved materials list or colors?
  • What does my insurer need to see after the replacement?
  • How will you handle skip sheathing and any damaged wood?

Frequently asked questions

Can I repair my shake roof instead of replacing it?

Small repairs are possible on a shake roof that's still in fair shape, but brittle shakes break easily when neighbors are replaced, and repairs don't change the fire rating. Once the roof is widely worn, replacement is usually the practical choice.

Can I use treated wood shakes again?

Some fire-retardant treated shakes can achieve a Class A rating as part of a specific assembly, but local rules and insurers vary. Many homeowners choose a non-wood material with a shake look instead.

How long does a wood shake roof replacement take?

It depends on the roof's size, complexity, material choice and how much decking is needed. We'll give you a schedule after the inspection.
