Fire Retardant Cedar Wood Shake

San Jose Cedar Shake Roofs

When roofing companies use the word shake, what they are referring to is a basic wooden shingle that traditionally is made from split logs, although modern times have broadened the term a little bit. Higher grade shakes are used to create long-lasting weather-resistant roofs with a rustic look to them. Fire-retardant Cedar Shake roofing systems offered in San Jose by Westshore Roofing do require a little more maintenance than some of our other roofing materials, due to wood’s permeability. But they create a unique look that you can be proud of when showing off your San Jose home.

The two most common sizes of wood shake are
1. Medium grade, ½ average thickness
2. Heavy grade, ¾ average thickness

Not all wood shakes are of the same quality. At Westshore we offer several grades of fire-retardant cedar shake roofing materials to San Jose customers, including:

1. Regular grade. Rough appearance, wood has lots of knots, many shakes are only 6-8” wide. (Not recommended).
2.“Select” grade. Most popular choice among our customers. Appearance is not as rough or irregular as the regular grade. Shakes are generally of 85% edge grain. Shake are wider than regular grade making for a better quality roof installation.
3. Premium grade. These are the best quality. More uniform in thickness and appearance. Wood is clear heartwood, 100% edge grain with a wide cut. Wood of this quality is less likely to cup and curl.

Cedar shakes are placed in pressure treatment cylinders where fire retardants are injected into the inner cells of the wood. The material then goes into a polymerization process and the fire retardants are locked into the wood. After 10 years of outdoor weathering and regular testing, the treatment has been deemed permanent.
