- which side of a wood shake or shingle goes "up"
Does it matter which side of a cedar shake is up? I have a client that likes the rough sawn side of the shingle. Does it affect the warranty? Thanks

Just to be clear on terminology, wood shingles are saw-cut on both sides and have smooth flat surfaces, while wood shakes are split (by hand or by machine) to produce a thicker and more irregular product. Wood shingles are saw-cut and have smooth flat surfaces, while wood shakes are split (by hand or by machine) to produce a thicker and more irregular product.
Wood shakes, the product named in your question about "which side up" are produced first by splitting a section of cedar or other suitable wood into a double-thickness piece, then a band saw is used to saw the split wood in half.
That's produces a sawn-smooth shake side that goes "down" away from the weather and a rougher split-surface exosure side of the shake that is placed "up" facing the weather.
The Cedar Shake and Shingle Bureau is one of the best authorities on wood shingle and shake installation specifications. This example installation summary http://www.cedarbureau.org/manuals/imperial/2015/RFI/RoofManual-0407-i-p4.pdf does not mention which side of a cedar shake is placed facing "up".
I think that's because there is an assumption when intalling split wood shakes that the sawn, flat sawn side of a cedar roofing shake always faces down.
The rough, uneven side of the split cedar shake faces "up" to the weather.
Why? OPINION: take a look at a roofing shake. Which side is more flat? The sawn side.
Now consider how horribly wavy and uneven will be the roof installation if the rough side is placed facing down, and how much more likely shake splits and roof leaks may be in that installation. Simply stepping on such a rough-side-down roofing shake will probably split it immediately.
Really, if your client wants a smooth-faced wood roof she should specify cedar shingles, not cedar shakes.
Now what about installation of a smoother wood shingle roof. Sawn shingles may have a rougher back surface.
I'd put that surface down, away from the weather. The smoother side of the wood shingle will shed water better, absorb less water, and have a longer life.
Here is the Bureau's summary instructions for wood shingles. Again you'll see no mention of rough side up or down. http://www.cedarbureau.org/manuals/imperial/2015/RFI/RoofManual-0407-i-p5.pdf

Roof Tiling & Slating, a Practical Guide, Kevin Taylor, Crowood Press (2008), ISBN 978-1847970237, If you have never fixed a roof tile or slate before but have wondered how to go about repairing or replacing them, then this is the book for you. Many of the technical books about roof tiling and slating are rather vague and conveniently ignore some of the trickier problems and how they can be resolved. In Roof Tiling and Slating, the author rejects this cautious approach. Kevin Taylor uses both his extensive knowledge of the trade and his ability to explain the subject in easily understandable terms, to demonstrate how to carry out the work safely to a high standard, using tried and tested methods.
This clay roof tile guide considers the various types of tiles, slates, and roofing materials on the market as well as their uses, how to estimate the required quantities, and where to buy them. It also discusses how to check and assess a roof and how to identify and rectify problems; describes how to efficiently "set out" roofs from small, simple jobs to larger and more complicated projects, thus making the work quicker, simpler, and neater; examines the correct and the incorrect ways of installing background materials such as underlay, battens, and valley liners; explains how to install interlocking tiles, plain tiles, and artificial and natural slates; covers both modern and traditional methods and skills, including cutting materials by hand without the assistance of power tools; and provides invaluable guidance on repairs and maintenance issues, and highlights common mistakes and how they can be avoided.
The author, Kevin Taylor, works for the National Federation of Roofing Contractors as a technical manager presenting technical advice and providing education and training for young roofers.
