Summary:

In 1913, the Agricultural Engineering Section of the Agricultural Experiment Station, in cooperation with the Engineering Experiment Station, organized a project in an attempt to find additional information with respect to durability of prepared roll roofings. Reasons assigned for the undertaking of the project were, 910 the use of the material was expected to increase, and (2) the users had no assurance other than the reputation of the manufacturer as to the qualities of the material. The purpose of the investigation was to determine quality factors of three-ply prepared roofings as they were sold on the market at that time. One roll, or square of each of 35 brands of prepared roll roofing, which were made by 19 manufacturers, was purchased on the open market and included in the experiment. This was sufficient maternal for one strip to be placed on the shed for weathering and enough in addition upon which to make laboratory tests. Table 1 gives general information and data of the roofing specimens.
