Building Code Changes� The material in this presentation is a summary of
minimum building code requirements � per the 2006 Alberta Building Code which is an
extension of the National Building Code of Canada
� Developed by National Research Council of Canada
� 2006 Building Code changes will be incorporated into all new building permits� The only way a contractor should build anything less
than code requirements would be
� The Authority have jurisdiction authorizing the deviation from code
� A design professional (architect, engineer) stamp of approval is obtained on the blueprints
Be sure to get detailed flashing requirementsfrom your builder’s blueprints

In Summary
� The 2006 flashing requirements
� have created additional complexity
� Number of locations requiring flashings has increased
� Configuration of the flashing
� Up dams
� “Leg” length may vary depending on application
� Will result in additional cost due to
� increased install time required
� increased amount of flashing materials
� Be sure to share you ideas and experiences with the Association members
� Improves the quality of our workmanship
� Minimizes issues for all members
