IBC 2006

In January, the International Code Council (ICC) published the International Building Code, 2006 Edition (IBC 2006). IBC 2006 contains a number of roofing-related revisions from the previous edition; you must be aware of these.

Asphalt shingles

The code has been revised to require asphalt shingles used on buildings located in areas where the basic wind speed is 110 mph (49 m/sec) to be tested in accordance with ASTM D3161, "Standard Test Method for Wind-resistance of Asphalt Shingles (Fan-Induced Method)," Class F (110 mph). As an alternative, the loads on and wind resistance of asphalt shingles now are permitted to be determined according to UL 2390, "Test Method for Measuring the Wind Uplift Coefficients for Asphalt Shingles," and ASTM D6381, "Standard Test Method for Measurement of Asphalt Shingle Mechanical Uplift Resistance."

Also, asphalt shingle packaging needs to bear a label indicating compliance with ASTM D3161 or listing from an approved testing agency, such as Underwriters Laboratories Inc., referencing UL 2390/ASTM D6381.
