The third downside is the price: The best grades of wood are very expensive.
Shingles. Shingles are sawn from either western red cedar or eastern white cedar; preference varies regionally, and lengths and grading rules differ between the two. The best shingles of either species are all clear heartwood, which is extremely durable but expensive. Installation costs also are high. Heartwood is naturally resistant to insects and decay, but the sapwood sometimes found in lower grades is not. Some grades also may contain knots above or even below the weather line, which may reduce life expectancy. Two more expensive options, rebutted and…
