Roof shingle testing laboratory testing services:
This article lists roof materials testing services and laboratories useful for testing roof shingles and other roof coverings for durability, wind uplift, granule loss, roof covering chemistry, and similar parameters.
Roof shingle testing laboratories support roofing manufacturers by testing shingle samples from the production line to maintain shingle quality control and to avoid manufacturing defects. These same laboratories may provide independent test services to roof failure investigators and insurance companies who are examining roofs for hail damage, storm damage, or other failures that may include defective roofing products.

Simple roof shingle tests performed by many labs may include moisture and density - in my opinion tests of questionable utility in assessing the cause of a roof failure. Tests of weight and tear resistance and impact resistance and low temperature flexibility are also peformed. A more complex asphalt shingle test performed by some roof shingle testing laboratories is the desaturation test. This procedure analyzes the extent of loss of asphalt from the shingle substrate. As roof shingles age the volatiles are lost from the original asphalt impregnation of the shingle substrate (organic or fiberglass). As the asphalt ages it becomes more dry and brittle and loses some of its adhesive properties.
Roofing tests are guided by a near deluge of ASTM standards - please see STANDARDS for ROOFING. For example (from the complete list given at my link at left)
ASTM D 3462 / ASTM D3462M - 09a - Standard Specification for Asphalt Shingles made from Glass Felt and Surfaced with Mineral Granules. [DF: refers to fiberglass-based asphalt shingles].
ASTM D4977 - 03(2009) Standard Test Method for Granule Adhesion to Mineral Surfaced Roofing by Abrasion
ASTM D6381 - 08 Standard Test Method for Measurement of Asphalt Shingle Mechanical Uplift Resistance [Wind resistance of shingles - DF]
The asphalt roof shingle desaturation test may look at
Loss of asphalt from the roof shingle
Loss of mineral granule coating that protects the roof shingle surface
Loss of other sealants or other treatments from the shingle surfaces or shingle body
Watch out: a desaturation test evaluates the condition of the shingle and may help assess its remaining life but the test alone, without an expert on-site inspection of the building and all roof surfaces, is in my opinion not a complete diagnostic of the cause of roof wear nor an assessment of the condition of the whole roof. Other critical information is observed on-site such as the condition of different roof slopes exposed to different conditions, variation in roofing over the same roof surfaces, building moisture, roof ventilation, even basement water entry or a history of ice dams that affect roof life. Other critical factors such as original shingle materials and shingle type, thickness, storage conditions, and plies or shingle design are crucial considerations that must be included in any roof assessment of life, condition, cause of damage, etc.

To begin with, there are many commercial testing labs available
today. There are fewer labs with roof material testing experience
and only a handful that can perform serious research. If
product testing on a new roof material is needed, most commercial
labs can provide that service. Weathered, non-performing
roof materials are much more difficult to analyze since the
ASTM product standards assume that new materials are being
tested. One can test the weathered or aged material according to
the new material standard but cannot declare failure if the results
fall below. Roof materials change as they weather and heat age;
the ASTM product standards cannot quantify this rooftop
change. Judgment, experience, and comparative reasoning are
used to opine the condition of aged roof materials.
Beware if the testing lab cannot provide an interpretation of
the results. That may be a tip off that they know how to conduct
the test but really do not understand what they are testing for
and how the roofing material may respond. A roof consultant
may want to interpret the results, since the test lab may not have
experienced staff or get to see the roof in question. A knowledgeable
roof consultant will use lab test results to help explain
what happened to the roof system.

Abstract: This paper describes the composition and function of each of the layers of a shingle.
The various types of shingles and their application are discussed. The more common problems
associated with asphalt shingles and the probable causes for these problems are
reviewed. The various standards pertaining to asphalt shingles are also discussed.

Abstract: Asphalt shingles surfaced with mineral granules have become an important roofing material, and the published specifications now in use do not appear to be sufficient to secure adequate quality. The results of the examination of sixteen brands of asphalt shingles that are sold for roofing are presented, together with comments on the different compositions which are encountered. Certain recommendations as to the direction in which specifications should be changed are suggested.

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.
