WRC Perfection RD Mill Shingles comes with below uses:

The Western Red Cedar No.1 Blue Label Perfection is the most common "cedar shingle" used for roofing worldwide. The Perfection shingle roof offers a clean, smooth, uniform visual. It has been used throughout the USA Northeast for decades. An easy product to install with great aesthetic value for many roof designs, it is also well known in most off-shore markets. We always recommend using a No.1 Grade Blue Label shingle for roofs and walls to ensure the best performance and appearance for primary buildings. This Perfection shingle is also used to produce the No.1 Re-Butted & Re-Jointed sidewall shingle - the most common siding shingle. The R&R shingle is manicured to speed application and give straight and parallel lines. The raw Perfection shingle can also be used on walls very effectively, albeit with a slightly less tailored end result.
