Slate Specification

The following slate roofing guide specification follows the MasterSpec format and is intended to be included with other sections for related work. This document references pages in Slate Roofs: Design and Installation Manual, 2010 Edition, and Technical Bulletins

The purpose of this 3-part specification is to provide a detailed description of the quality required, materials, workmanship, dimensions, etc. of work to be done so designers, architects, engineers, or roof consultants can specify a slate roof properly. It provides clear instructions on the intent, performance and construction of the project. In this document you will find key information related to:

Slate – Quality, shape, and color

Nails – Length, material, thickness

Underlayments –   Installation & product acceptability

Tools – Rippers, hammers, cutters

Installation – Layout, field slates, eaves, valleys, ridge, hip

Removal – Replacing, repair techniques

References and Standards – NSA, ASTM, FM, and the Florida Building Code

It would be beneficial to future users of this specification sheet if current designers have any feedback in working with it. Please send all thoughts to and they will be reviewed. Your help is greatly appreciated.
