What Is Cedar Shake Treatment?

Cedar shake treatment is the process of applying fire-retardant and preservative chemicals to cedar wood roofing.

This helps protect your roof against:

  • Fire (especially important in areas prone to wildfires)

  • Decay and rot

  • Mold and mildew

  • Insect damage (like termites and carpenter ants)

There are two common types of treatment:

  • Pressure-treated at the mill: Done before the shingles are shipped.

  • Topical treatment on-site: Sprayed or brushed on after installation.

Why It Matters in Georgia

Georgia’s hot, humid weather creates the perfect environment for wood decay, algae, and insect infestations. Untreated cedar shakes can break down faster and pose a fire risk.

Properly treated cedar shakes last longer and are safer.

Ask Your Roofer These Questions:

  • Is the cedar shake fire-rated?

  • Is the treatment pressure-applied or done on-site?

  • Is it code-compliant for my area?

Some counties in Georgia may require a specific fire rating or type of treatment. Code compliance matters for safety and resale value.

FAQ: Cedar Shake Treatment

What does fire treatment mean for cedar shakes?

Fire treatment uses a chemical solution to slow down how quickly cedar shakes can catch fire. Look for products with a Class B or Class C fire rating, depending on local codes.

Is pressure-treated cedar better?

Yes. Pressure-treated cedar has preservatives forced deep into the wood, offering longer-lasting protection than surface-level treatments.

Can cedar shake be treated after installation?

Yes, but it’s less effective. On-site treatments are better than nothing, but pressure treatment at the mill gives more durable results.

How long does cedar shake treatment last?

  • Pressure-treated: Up to 30 years depending on quality and conditions.

  • On-site treatment: Typically needs reapplication every 5–10 years.
