Slate roofing is considered a high-quality, durable, and
aesthetically pleasing material which receives considerable focus
in both the sale of properties and in the evaluation of building condition. Also see SLATE ROOF COLORS.
This article series assists home inspectors, building buyers or building owners, and roofing contractors in
evaluating the condition of slate roofs by providing photos of various slate materials, patterns, defects,
and conditions. Also see How to Inspect & Repair Slate Roofs for a detailed article about evaluating the condition of slate roofing and repairing worn or damaged slate roofs.
A Photographic Guide to Slate Roof Patterns
As we emphasized at
SLATE ROOF INSPECTION & REPAIR our main article on slate repairs, opinions run heavier than actual data.
The abandonment of good slate roofs which should have been repaired
is a financial shame and the destruction of a valued asset. At the
same time, careless optimism about a bad slate roof which is at the
end of its life risks an angry inspection client.

- 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.
