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)

The asphalt roof shingle desaturation test may look at

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. is an independent publisher of building, environmental, and forensic inspection, diagnosis, and repair information for the public - we have no business nor financial connection with any manufacturer or service provider discussed at our website.
