Use this CSI 3 part SimpleSpecs™ master specification to specify wood shingles and shake roof shingles and underlayment.
The term shingles refers to machine-cut wood shingles that are slightly thinner and more uniform. Shakes refers to hand-cut shingles that are slightly thicker and have a rougher texture.
Shingles are commonly available in Cedar, less so in Pine, Cypress, and other wood species. Cedar shingles have proven to be both weather-resistant and cost-effective.
Shingles are also used on vertical surfaces such as gable ends.
Some manufacturers offer shingles that are prefabricated into sheets for simplified installation. Shingles are also available with a fire-retardant treatment, although the effectiveness of this treatment decreases with time and weather exposure.
Underlayment requirements vary depending on roof slope, from a single layer of roofing felt to rubberized asphalt and synthetic. Similarly, valley construction varies depending on slope.
For information regarding selection and detailing of wood shingles refer to the National Roofing Contractors Association (NRCA) Roofing Manual: Steep-Slope Roof Systems, available from NRCA at www.nrca.net.

The SimpleSpecs™ master specs concept
Design professionals are accustomed to seeing lengthy project specifications, so why is SimpleSpecs™ so short?
Specifications have grown evermore wordy over the years for several reasons:
The mistaken belief that specifications must be lengthy and legal-sounding to be enforceable. In fact, quite the opposite is true. Having shorter, easily understood specifications makes us less likely to have problems in the field.
A belief that having lots of words protects us from a Contactor making mistakes. There is no way to include enough statements to protect yourself from a bad contractor, regardless of the length of your specification.
Our desire to be in control of the project by specifying means and methods instead of including simple, enforceable statements.
Easier to Edit
SimpleSpecs™ is written as a series of Microsoft word files that include statements that affect construction costs or overall quality and are far simpler to edit than other master specification systems.
Each SimpleSpecs™ specification section is non-proprietary and includes three manufacturers that meet the specified reference standards, descriptive, or performance-based requirements. They are written to allow any listed manufacturers to provide the specified products.
Hidden Guide Text
Each SimpleSpecs™ specification section includes hidden text to inform and guide users in editing the specifications to suit project conditions.
SimpleSpecs™ sections are edited using pre-defined options that are contained in [brackets] or by selecting optional text separated by "OR" statements. Paragraph and page numbering are included as automatic codes, eliminating the need to renumber when revisions are made manually. Global changes to headers, footer, terms, font colors and phrases are easily updated using a third-party search and replace software, available through ZeroDocs.com.
