Cedar vs. redwood material properties

Cedar and redwood are the two most popular wood species for roofing, each offering unique characteristics:

Class C fire rating and treatment options

One of the primary concerns with wood roofing is its fire resistance. Untreated wood shakes and shingles typically carry a Class C fire rating, the lowest classification for roofing materials. However, advanced treatment processes can significantly improve fire resistance:

• Pressure-impregnated fire retardants can upgrade wood roofing to a Class A fire rating
• These treatments often include preservatives to enhance resistance to decay and insect infestation
• Some treatments can extend the lifespan of wood roofing by 5-10 years or more

It's crucial to check local building codes, as some areas may require specific fire ratings for wood roofing materials, especially in wildfire-prone regions.

Taper sawn vs. Hand-Split textures

The texture of wood shakes and shingles can significantly impact the overall appearance of your roof. The two primary textures are:

1. Taper Sawn : Machine-cut on both sides for a smoother, more uniform appearance. These are often preferred for a more refined look and can be easier to install.
2. Hand-Split : Split by hand on one side for a more rustic, textured appearance. These provide greater depth and shadow lines, enhancing the natural character of the wood.

The choice between taper sawn and hand-split textures often depends on the architectural style of the home and personal preference. Hand-split shakes typically offer better weather resistance due to their thicker profile, but they can be more challenging to install uniformly.

Preservation techniques: CCA vs. ACQ treatments

To enhance the longevity and performance of wood roofing, various preservation treatments are available. The two most common are:

• CCA (Chromated Copper Arsenate) : A highly effective preservative that has been used for decades. However, concerns about arsenic content have led to restrictions on its use in residential applications in many areas.
• ACQ (Alkaline Copper Quaternary) : A more environmentally friendly alternative that provides excellent protection against decay and insects without the use of arsenic.

When selecting wood roofing materials, it's important to inquire about the specific preservation treatments used and their environmental impact. Many manufacturers now offer eco-friendly alternatives now offer excellent protection without the environmental concerns associated with CCA.
