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.
If your roofing problem is a concern about
Defective roofing product such as manufacturing defects in asphalt shingles:
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 performed.
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 this live link)
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.

Excerpt:
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.

- looking for roof test lab to send samples from time to time- TPO test cut
George
Thank you for contacting us, as I certainly share your interesting in roofing installation, failures, inspection, diagnosis, and repair - but our forensic lab does not work with roofing test cuts, though we do refer our readers to the roof test labs listed on this page.
In my opinion your tape shows a damaged section that would certainly not give a reliable bond.
For other readers:
TPO Roofing or Thermplastic Polyolefin Roofing is an example of a single ply or membrane roof covering currently widely used on low slope commercial buildings.

- example roofing sample TPO Roofing Test Cut
We are looking for lab to send samples from time to time. I teach a roofing course for industial flat roofing membranes.
This [photo above] is a sample of a TPO cut test.
I show the class cut tests every course.
Please see photo attached. Would your lab consider this a pass or fail? George Wilson, Cindott Inc, 416 606 3270, gwilson18@cogeco.ca. www.roofingtrainingcourse.com

Anonymous asked:
would your lab test reveal the age of a 3-tab shingle
Moderator reply:
At TEST LABS - ROOF SHINGLE https://inspectapedia.com/roof/Roof_Shingle_Test_Labs.php you can find roof and shingle test labs that can do what you need
- keep in mind that nobody is going to tell you the absolute chronological age of a shingle unless you have a receipt or manufacturing date; rather one can tell the wear-age.

I guess what I'm asking is, how evenly spread out is abestos in roof shingles? Could I miss it?

How many samples should I take off of a roof to have tested in a lab for asbestos. Is one sufficient?

Possibly, Steve though that sounds odd to me. Usually the minerals in asphalt roofing are copper or possibly zinc, both of which are not particularly attracted to a magnet. There might be metallic fragments in slag or other waste products that might be used in the production of some mineral granules used to coat asphalt shingles. And there might be other metals used in some reflective roof granule coatings.

I passed a magnet through a pile of granules in the gutter and found many flakes of metal. Are metal flakes part of the "mineral" coat?

- shingle product ordered vs installed.
Here are some easy things to check to see if what you paid for is what you got on your roof before looking closely at the shingles themselves
Check what you think you ordered - and what is written in your roof installation contract - against the roofing manufacturer's product catalog. Some shingle types can be immediately distinguished, such as notched 3-tab shingles vs. laminated architectural shingles.
Look at the roof covering material packaging to identify the brand and product model and even the production run number
Ask your contractor for proof of purchase: an invoice from her building supplier, showing what was bought to put on your roof

- product I ordered is not the product that was actually installed.
I feel like the product I ordered is not the product that was actually installed. How do I get a verification. I am certain it is not the same color as I have photos and pieces of my previous roof that was installed less than 1 year ago. The product was the exact same invoice order but the shingles themselves are very thin and as before WRONG color (beyond a variation). Is this a service provided by your company?
