Roofing Shingles Vs. Cedar Shakes Costs, Plus Pros & Cons in 2019

In this guide, we present a side-by-side comparison of cedar shingles and shakes vs. asphalt roofing, with focus on on material composition, installation costs, plus pros and cons and ROI of each option. Let’s get started!

The Difference Between Wood Shingles & Shakes

When used in roof covering, wood can be either shakes or shingles. Wood shakes have been used for centuries. They are split from logs and often left as split to retain the textured, rough-hewn effect.

A wood shake is instantly recognizable by its thick butt end. With the advent of commercial sawmills a wood shake was often sawn after splitting to achieve a uniform back side.

These sawmills also produced a completely uniform product with an even taper and identical thickness by sawing shakes on both sides. This manufactured product is known as a wood shingle.

California redwood, western red cedar, cypress, spruce and pine are all used to manufacture wood shakes and shingles. Cedar is the most popular wood for shakes, southern yellow pine is also popular. Wood shakes and shingles can be pressure treated with fire retardants and chemical preservatives.

Types of Asphalt Shingles

Asphalt or composition shingles are most commonly constructed from organic material or fiberglass. Asphalt shingles are built upon a base or mat that was originally made of absorbent cotton rags.

Later, more readily available wood pulp or paper replaced the natural fibers. Asphalt was poured onto that base, known as “felt”.

In the 1970s, fibrous glass was introduced, which did not rot like the organic materials. Today, 95 percent of asphalt shingles feature fiberglass felt.

Cedar Shingles/Shakes Cost Vs. Asphalt

In the roofing industry, an 18-inch wood shingle is referred to as “Perfection” and 24-inch wide shingles are known as “Royal.” A wood shake is a premium product, costing around $3.50 per square foot versus $2.50 a square foot for wood shingles.

The most expensive option for shingling a roof is wood shakes — between $6.50 to $11.00 per square foot or $650 and $1,100 per square (100 square feet), installed.

Wood shingles are slightly less pricey at $4.50 to $9.00 per square foot or $450 to $900 per square, installed.

For comparison, asphalt roofing can cost as little as $2.75 to $5.50 per square foot or $350 to $550 per square, installed.

So, why do homeowners opt for the much more expensive wood shingling? The answer is…

Aesthetics

It is hard to beat the appearance of a natural wood roof. If you are making over a traditional older house, cedar roofing is probably the historically appropriate choice. Not that asphalt shingles are an unattractive alternative.

Asphalt shingles come in a wide variety of colors and shapes and patterned asphalt roofs can be eye-catching in their own right.

Beyond looking great, wood shingling does not win many comparison battles with its asphalt-covered competition. Let’s explore some of the pros and cons up on your roof…

Longevity

Life expectancy for both asphalt and wood shingles is a tricky matter. Let’s tick off all the factors that can affect the longevity of a roof covering: quality of installation, diligence of maintenance, quality of materials, age of the house, overhanging trees, climate and foot traffic.

Chemically treated wood will outlast untreated shakes and shingles and a shake will survive longer than a shingle. Both asphalt and treated wood shingles can survive up to 30 years on a roof, given ideal conditions.

Durability Cedar shingles are resistant to insects but not large amounts of rain. Cedar shakes in a damp environment are susceptible to mold and mildew and rot.

Sap from overhanging trees will encourage mildew. When rot sets in it has likely affected more than a single shake and the entire roof is a candidate for replacement.

Cleaning Costs

Asphalt has its own weather issues. Algae is more likely to take hold on an asphalt roof than cedar shakes. While this will not hamper your roof’s protection abilities, it does lead to unsightly staining and premature replacement on appearance grounds, especially at resale time.

Cleaning either a asphalt or wood shingle roof with a solution of water and bleach applied professionally and gently with a powerwasher will run from $25 to $30 per square. And this is a job best left to competent professionals as a poorly handled powerwasher can wreak havoc on roof shingles.

Flammability

Some building codes where fire is a danger restrict or ban the use of wood shingling altogether. Asphalt shingles have a high resistance to flames.

Keep in mind that wood shakes and shingles can be pressure treated with fire retardants and chemical preservatives.

Wind and Impact Resistance

Cedar shakes and shingles are the clear winner here. Both have proven to be highly impact-resistant and have tested to withstand wind speeds of up to 245 miles per hour (which your house will never see).

Asphalt shingles will, however, blow off a roof in high winds. Fallen branches are also much more likely to damage an asphalt shingle that a wooden one.

Maintenance

Cedar is a high maintenance material. For starters, the wood needs to breathe and the roof must be kept clear of leaves, branches and debris.

Gutters must be regularly cleaned and ventilation kept open for air to flow around the shakes and shingles.

Topical treatments can be applied as water repellents and ultraviolet inhibitors that can prevent graying of a roof.

If individual shakes or shingles are required they will match the composition and color of the original roof – score one point for cedar.

While algae will not impair the performance of asphalt shingles, mosses that grow on a damp roof can cause the edges to lift or curl leaving them vulnerable to a blow-off in storms.

Moss can be removed with a 50:50 mix of laundry-strength liquid chlorine bleach and water soaked with a low-pressure sprayer.

The moss will eventually loosen and can be swept off the roof. It will return, however, if many of the same measures as keeping a wood roof dry – trimming tree branches, removing debris and clearing gutters — are not followed. Replacing individual shingles is often a DIY job.

ROI, Property Valuations, and Curb Appeal Considerations

In terms of property valuations, replacing a cedar roof with asphalt will instantly diminish the value of your property. — On some historic homes, as well as homes surrounded by other homes roofed with cedar, such as in historic districts/neighborhoods, this may not even be an option to begin with.

However, if you must replace a cedar roof with something else, then opting for a metal roof rather than asphalt will help preserve the valuation and curb appeal of your property.

Conclusion

On the cost and maintenance considerations – the “Big Two” for most homeowners – asphalt shingles are the clear choice over wood shakes.

And in fact, about 70 percent of American roofs are covered with asphalt shingles today. On the other hand, those wood shingled-roofs just look so darn good, don’t they? 😉

    I purchased my home 13 years ago and was told the original cedar shake roof was under the shingle roof. I need to replace the roof (missing shingles blown off) I live in Michigan, do I have to have the original roof torn off or should I just replace the asphalt shingle roof?

      It’s not ideal, but not uncommon to have an asphalt roof installed over cedar shakes. While the removal of original shakes is the best way to go from the roof integrity (ventilation, preventing termite infestation, moisture problems and rotting of the wood) and engineering perspective (maximum weight that your roof trusses can support), it can be very expensive to remove the original roof, have it hauled away, and having to install plywood or OSB before a new roof can be installed. Most cedar shake roofs are installed over strips of woods with large spaces in between. An asphalt roof does require a solid substrate. If money is not an issue, then do a complete tear-off.
